The installation from source is first described, together with the available command line arguments. The user interface is then presented, with all of the customizable options that change `calcurse` behavior. Last, bug reporting procedure is explained, as well as the way one can contribute to `calcurse` development. Introduction ------------ `calcurse` is a text-based calendar and scheduling application. It helps keeping track of events, appointments and everyday tasks. A configurable notification system reminds user of upcoming deadlines, and the curses based interface can be customized to suit user needs. All of the commands are documented within an online help system. Overview -------- Creation history ~~~~~~~~~~~~~~~~ Frederic started thinking about this project when he was finishing his Ph.D. in Astrophysics as it started to be a little hard to organize himself and he really needed a good tool for managing his appointments and todo list. Unfortunately, he finished his Ph.D. before finishing `calcurse` but he continued working on it, hoping it would be helpful to other people. In mid-2010, Lukas took over development of `calcurse` and is now the main contributor and reviewer of patches. But why `calcurse` anyway? Well, it is simply the concatenation of *cal*endar and *curse*s, the name of the library used to build the user interface. Important features ~~~~~~~~~~~~~~~~~~ `Calcurse` is multi-platform and intended to be lightweight, fast and reliable. It is to be used inside a console or terminal, locally or on a distant machine within an ssh (or similar) connection. `Calcurse` can be run in two different modes : interactive or non-interactive mode. The first mode allows oneself to view its own personal organizer almost everywhere, thanks to the text-based interface. The second mode permits to easily build reminders just by adding `calcurse` with appropriate command line arguments inside a cron tab or within a shell init script. Moreover, `calcurse` was created with the end-user in mind, and tends to be as friendly as possible. This means a complete on-line help system, together with having all of the possible actions displayed at any time inside a status bar. The user interface is configurable, and one can choose between several color and layout combinations. Key bindings are also configurable, to fit everyone's needs. Last, a configurable notification system reminds user of upcoming appointments. The reminders are sent even if the user's interface is not running, as calcurse is able to run in background. Installation ------------ Requirements ~~~~~~~~~~~~ ncurses library ^^^^^^^^^^^^^^^ `Calcurse` requires only a `C` compiler, such as `cc` or `gcc`, and the `ncurses` library. It would be very surprising not to have a valid `ncurses` library already installed on your computer, but if not, you can find it at the following url: http://ftp.gnu.org/pub/gnu/ncurses/ NOTE: It is also possible to link `calcurse` against the `ncursesw` library (ncurses with support for unicode). [[install_requirements_gettext]] gettext library ^^^^^^^^^^^^^^^ `calcurse` supports internationalization (*i18n* hereafter) through the `gettext` utilities. This means `calcurse` can produce multi-lingual messages if compiled with native language support (i.e. *NLS*). However, *NLS* is optionnal and if you do not want to have support for multi-lingual messages, you can disable this feature. This is done by giving the `--disable-nls` option to `configure` (see section <>). To check if the `gettext` utilities are installed on your system, you can search for the `libintl.h` header file for instance: ---- $ locate libintl.h ---- If this header file is not found, then you can obtain the `gettext` sources at the following url : http://ftp.gnu.org/pub/gnu/gettext/ NOTE: Even if `libintl.h` is found on your system, it can be wise to specify its location during the <>, by using the `--with-libintl-prefix` option with `configure`. Indeed, the `configure` could fail to locate this library if installed in an uncommon place. [[install_process]] Install process ~~~~~~~~~~~~~~~ First you need to gunzip and untar the source archive: ---- $ tar zxvf calcurse-4.5.1.tar.gz ---- Once you meet the requirements and have extracted the archive, the install process is quite simple, and follows the standard three steps process: ---- $ ./configure $ make $ make install # (may require root privilege) ---- Use `./configure --help` to obtain a list of possible options. calcurse basics --------------- Invocation ~~~~~~~~~~ [[basics_invocation_commandline]] Command line arguments ^^^^^^^^^^^^^^^^^^^^^^ `calcurse` takes the following options from the command line (both short and long options are supported): `-a, --appointment`:: Print the appointments and events for the current day and exit. Equivalent to `-Q --filter-type cal`. The calendar from which to read the appointments can be specified using the `-c` flag. `-c , --calendar `:: Specify the calendar file to use. The default calendar is `~/.calcurse/apts` (see section <>). This option has precedence over `-D`. `-d , --day `:: Print the appointments for the given date or for the given number of upcoming days, depending on the argument format. Two possible formats are supported: + -- * a date (possible formats described below). * a number `n`. -- + In the first case, the appointment list for the specified date will be returned, while in the second case the appointment list for the `n` upcoming days will be returned. As an example, typing `calcurse -d 3` will display your appointments for today, tomorrow, and the day after tomorrow. The first form is equivalent to `-Q --filter-type cal --from `, the second form is equivalent to `-Q --filter-type cal --days `. + Note: as for the `-a` flag, the calendar from which to read the appointments can be specified using the `-c` flag. `--daemon`:: Start calcurse in background mode. Restart if the daemon was already running. See <> for details. `--days `:: Specify the length of the range (in days) when used with `-Q`. Cannot be combined with `--to`. `-D , --directory `:: Specify the data directory to use. If not specified, the default directory is `~/.calcurse/`. `--filter-type `:: Ignore any items that do not match the type mask. See <> for details. `--filter-pattern `:: Ignore any items with a description that does not match the pattern. See <> for details. `--filter-start-from `:: Ignore any items that start before a given date. See <> for details. `--filter-start-to `:: Ignore any items that start after a given date. See <> for details. `--filter-start-after `:: Only include items that start after a given date. See <> for details. `--filter-start-before `:: Only include items that start before a given date. See <> for details. `--filter-start-range `:: Only include items within a given range. See <> for details. `--filter-end-from `:: Ignore any items that end before a given date. See <> for details. `--filter-end-to `:: Ignore any items that end after a given date. See <> for details. `--filter-end-after `:: Only include items that end after a given date. See <> for details. `--filter-end-before `:: Only include items that end before a given date. See <> for details. `--filter-end-range `:: Only include items within a given range. See <> for details. `--filter-priority `:: Only include items with a given priority. See <> for details. `--filter-completed`:: Only include completed TODO items. See <> for details. `--filter-uncompleted`:: Only include uncompleted TODO items. See <> for details. `--format-apt `:: Specify a format to control the output of appointments in non-interactive mode. See the <> section for detailed information on format strings. `--format-recur-apt `:: Specify a format to control the output of recurrent appointments in non-interactive mode. See the <> section for detailed information on format strings. `--format-event `:: Specify a format to control the output of events in non-interactive mode. See the <> section for detailed information on format strings. `--format-recur-event `:: Specify a format to control the output of recurrent events in non-interactive mode. See the <> section for detailed information on format strings. `--format-todo `:: Specify a format to control the output of todo items in non-interactive mode. See the <> section for detailed information on format strings. `--export-uid`:: When exporting items, add the hash of each item to the exported object as an UID property. `-F`, `--filter`:: Read items from the data files and write them back. The filter interface can be used to drop specific items. Be careful with this option, specifying a wrong filter might result it data loss! It is highly recommended to test the effect of filters with -G first. See also: <>. `--from `:: Specify the start date of the range when used with `-Q`. `-g, --gc`:: Run the garbage collector for note files and exit. `-G, --grep`:: Print appointments and TODO items using the calcurse data file format. The filter interface can be used to further restrict the output. See also: <>. `-h, --help`:: Print a short help text describing the supported command-line options, and exit. `-i , --import `:: Import the icalendar data contained in `file`. `-l , --limit `:: Limit the number of results printed to 'num'. `--dump-imported`:: When importing items, print each newly created object to stdout. Format strings can be used to specify which details are printed. See also: <>. `-n, --next`:: Print the next appointment within upcoming 24 hours and exit. The indicated time is the number of hours and minutes left before this appointment. + Note: the calendar from which to read the appointments can be specified using the `-c` flag. `-q`, `--quiet`:: Be quiet. Do not show system dialogs. `-Q, --query`:: Print all appointments inside a given query range, followed by all TODO items. The query range defaults to the current day and can be changed by using the `--from` and `--to` (or `--days`) parameters. The filter interface can be used to further restrict the output. See also: <>. `-r[num], --range[=num]`:: Print events and appointments for the num number of days and exit. If no num is given, a range of 1 day is considered. Equivalent to `-Q --filter-type cal --days `. `--read-only`:: Don't save configuration nor appointments/todos. + WARNING: Use this this with care! If you run an interactive calcurse instance in read-only mode, all changes from this session will be lost without warning! `-s[date], --startday[=date]`:: Print events and appointments from date and exit. If no date is given, the current day is considered. Equivalent to `-Q --filter-type cal --from `. `-S, --search=`:: When used with the `-a`, `-d`, `-r`, `-s`, or `-t` flag, print only the items having a description that matches the given regular expression. Equivalent to `-Q --filter-pattern `. `--status`:: Display the status of running instances of calcurse. If calcurse is running, this will tell if the interactive mode was launched or if calcurse is running in background. The process pid will also be indicated. `-t[num], --todo[=num]`:: Print the `todo` list and exit. If the optional number `num` is given, then only uncompleted todos having a priority equal to `num` will be returned. The priority number must be between 1 (highest) and 9 (lowest). It is also possible to specify `0` for the priority, in which case only completed tasks will be shown. Equivalent to `-Q --filter-type todo`, combined with `--filter-priority` and `--filter-completed` or `--filter-uncompleted`. `--to `:: Specify the end date of the range when used with `-Q`. Cannot be combined with `--days`. `-v, --version`:: Display `calcurse` version and exit. `-x[format], --export[=format]`:: Export user data to specified format. Events, appointments and todos are converted and echoed to stdout. Two possible formats are available: ical and pcal (see section <> below). If the optional argument `format` is not given, ical format is selected by default. + Note: redirect standard output to export data to a file, by issuing a command such as: + ---- $ calcurse --export > my_data.dat ---- NOTE: The `-N` option has been removed in calcurse 3.0.0. See the <> section on how to print note along with appointments and events. [[basics_filters]] Filters ^^^^^^^ Filters can be used to restrict the set of items which are loaded from the appointments file when using calcurse in non-interactive mode. The following filters are currently supported: `--filter-hash `:: Only include items with a hash starting with the specified pattern. The pattern can be inverted by prepending an exclamation mark (`!`). `--filter-type `:: Ignore any items that do not match the type mask. The type mask is a comma-separated list of valid type descriptions which include `event`, `apt`, `recur-event`, `recur-apt` and `todo`. You can also use `recur` as a shorthand for `recur-event,recur-apt` and `cal` as a shorthand for `event,apt,recur`. `--filter-pattern `:: Ignore any items with a description that does not match the pattern. The pattern is interpreted as extended regular expression. `--filter-start-from `:: Ignore any items that start before a given date. `--filter-start-to `:: Ignore any items that start after a given date. `--filter-start-after `:: Only include items that start after a given date. `--filter-start-before `:: Only include items that start before a given date. `--filter-start-range `:: Only include items with a start date that falls within a given range. A range consists of a start date and an end date, separated by a comma. `--filter-end-from `:: Ignore any items that end before a given date. `--filter-end-to `:: Ignore any items that end after a given date. `--filter-end-after `:: Only include items that end after a given date. `--filter-end-before `:: Only include items that end before a given date. `--filter-end-range `:: Only include items with an end date that falls within a given range. A range consists of a start date and an end date, separated by a comma. `--filter-priority `:: Only include items with a given priority. `--filter-completed`:: Only include completed TODO items. `--filter-uncompleted`:: Only include uncompleted TODO items. [[basics_format_strings]] Format strings ^^^^^^^^^^^^^^ Format strings are composed of printf()-style format specifiers -- ordinary characters are copied to stdout without modification. Each specifier is introduced by a `%` and is followed by a character which specifies the field to print. The set of available fields depends on the item type. Format specifiers for appointments ++++++++++++++++++++++++++++++++++ `s`:: Print the start time of the appointment as UNIX time stamp `S`:: Print the start time of the appointment using the `hh:mm` format `d`:: Print the duration of the appointment in seconds `e`:: Print the end time of the appointment as UNIX time stamp `E`:: Print the end time of the appointment using the `hh:mm` format `m`:: Print the description of the item `n`:: Print the name of the note file belonging to the item `N`:: Print the note belonging to the item Format specifiers for events ++++++++++++++++++++++++++++ `m`:: Print the description of the item `n`:: Print the name of the note file belonging to the item `N`:: Print the note belonging to the item Format specifiers for todo items ++++++++++++++++++++++++++++++++ `p`:: Print the priority of the item `m`:: Print the description of the item `n`:: Print the name of the note file belonging to the item `N`:: Print the note belonging to the item Examples ++++++++ `calcurse -r7 --format-apt='- %S -> %E\n\t%m\n%N'`:: Print appointments and events for the next seven days. Also, print the notes attached to each regular appointment (simulates `-N` for appointments). `calcurse -r7 --format-apt=' - %m (%S to %E)\n' --format-recur-apt=' - %m (%S to %E)\n'`:: Print appointments and events for the next seven days and use a custom format for (recurrent) appointments: ` - Some appointment (18:30 to 21:30)`. `calcurse -t --format-todo '(%p) %m\n'`:: List all todo items and put parentheses around the priority specifiers. Extended format specifiers ++++++++++++++++++++++++++ Extended format specifiers can be used if you want to specify advanced formatting options. Extended specifiers are introduced by `%(` and are terminated by a closing parenthesis (`)`). The following list includes all short specifiers and corresponding long options: * `s`: `(start)` * `S`: `(start:epoch)` * `e`: `(end)` * `E`: `(end:epoch)` * `d`: `(duration)` * `r`: `(remaining)` * `m`: `(message)` * `n`: `(noteid)` * `N`: `(note)` * `p`: `(priority)` The `(start)` and `(end)` specifiers support strftime()-style extended formatting options that can be used for fine-grained formatting. Additionally, the special formats `epoch` (which is equivalent to `(start:%s)` or `(end:%s)`) and `default` (which is mostly equivalent to `(start:%H:%M)` or `(end:%H:%M)` but displays `..:..` if the item doesn't start/end at the current day) are supported. The `(remaining)` and `(duration)` specifiers support a subset of the strftime()-style formatting options, along with two extra qualifiers. The supported options are `%d`, `%H`, `%M` and `%S`, and by default each of these is zero-padded to two decimal places. To avoid the zero-padding, add `-` before the formatting option (for example, `%-d`). Additionally, the `E` option will display the total number of time units until the appointment, rather than showing the remaining number of time units modulo the next larger time unit. For example, an appointment in 50 hours will show as 02:00 with the formatting string `%H:%M`, but will show 50:00 with the formatting string `%EH:%M`. Note that if you are combining the `-` and `E` options, the `-` must come first. The default format for the `(remaining)` specifier is `%EH:%M`. There are two additional long format specifiers that do not have any corresponding short options. They can be used to print an item's hash or its internal representation and were designed to be used for scripting: * `(hash)` * `(raw)` [[basics_invocation_variable]] Environment variable for i18n ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `calcurse` can be compiled with native language support (see <>). Thus, if you wish to have messages displayed into your native language, first make sure it is available by looking at the `po/LINGUAS` file. This file indicates the set of available languages by showing the two-letters corresponding code (for exemple, *fr* stands for french). If you do not find your language, it would be greatly appreciated if you could help translating `calcurse` (see the <> section). If your language is available, run `calcurse` with the following command: ---- $ LC_ALL=fr_FR calcurse ---- ... where *fr_FR* is the locale name in this exemple, but should be replaced by the locale corresponding to the desired language. You should also specify the charset to be used, because in some cases the accents and such are not displayed correctly. This charset is indicated at the beginning of the po file corresponding to the desired language. For instance, you can see in the fr.po file that it uses the iso-8859-1 charset, so you could run `calcurse` using the following command: ---- $ LC_ALL=fr_FR.ISO8859-1 calcurse ---- Other environment variables ^^^^^^^^^^^^^^^^^^^^^^^^^^^ The following environment variables affect the way `calcurse` operates: `VISUAL`:: Specifies the external editor to use for writing notes. `EDITOR`:: If the `VISUAL` environment variable is not set, then `EDITOR` will be used as the default external editor. If none of those variables are set, then `/usr/bin/vi` is used instead. `PAGER`:: Specifies the default viewer to be used for reading notes. If this variable is not set, then `/usr/bin/less` is used. Hooks ~~~~~ You can place scripts in `$HOME/.calcurse/hooks/` to trigger actions at certain events. To enable a hook, add a script with one of the following names to this directory. Also make sure the scripts are executable. *pre-load*:: Executed before the data files are loaded. *post-load*:: Executed after the data files are saved. *pre-save*:: Executed before the data files are loaded. *post-save*:: Executed after the data files are saved. Some examples can be found in the `contrib/hooks/` directory of the calcurse source tree. User interface ~~~~~~~~~~~~~~ Non-interactive mode ^^^^^^^^^^^^^^^^^^^^ When called with at least one of the following arguments: `-a`, `-d`, `-h`, `-n`, `-t`, `-v`, `-x`, `calcurse` is started in non-interactive mode. This means the desired information will be displayed, and after that, `calcurse` simply quits and you are driven back to the shell prompt. That way, one can add a line such as `calcurse --todo --appointment` in its init config file to display at logon the list of tasks and appointments scheduled for the current day. [[basics_interface_interactive]] Interactive mode ^^^^^^^^^^^^^^^^ NOTE: Key bindings that are indicated in this manual correspond to the default ones, defined when `calcurse` is launched for the first time. If those key bindings do not suit user's needs, it is possible to change them within the keys configuration menu (see <>). When called without any argument or only with the `-c` option, `calcurse` is started in interactive mode. In this mode, you are shown an interface containing three different panels which you can browse using the `TAB` key, plus a notification bar and a status bar (see figure below). ---- appointment panel---. .---calendar panel | | v v +------------------------------------++----------------------------+ | Appointments || Calendar | |------------------------------------||----------------------------| | (|) April 6, 2006 || April 2006 | | ||Mon Tue Wed Thu Fri Sat Sun | | || 1 2 | | || 3 4 5 6 7 8 9 | | || 10 11 12 13 14 15 16 | | || 17 18 19 20 21 22 23 | | || 24 25 26 27 28 29 30 | | || | | |+----------------------------+ | |+----------------------------+ | || ToDo | todo | ||----------------------------| panel | || | | | || | | | || |<--. | || | +------------------------------------++----------------------------+ |---[ Mon 2006-11-22 | 10:11:43 ]---(apts)----> 01:20 :: lunch <---|<--. +------------------------------------------------------------------+ notify-bar | ?

Depending on the selected view, the calendar could either display a monthly (default as shown in previous figure) or weekly view. The weekly view would look like the following: ---- +------------------------------------+ | Calendar | |----------------------------(# 13)--| | Mon Tue Wed Thu Fri Sat Sun | | 29 30 31 01 02 03 04 | | <----+-- slice 1: 00:00 to 04:00 AM | -- -- -- -- -- -- | | <----+-- slice 2: 04:00 to 08:00 AM | -- -- -- -- -- -- | | <----+-- slice 3: 08:00 to 12:00 AM | - -- -- -- -- -- -- - <-+-- midday | <----+-- slice 4: 12:00 to 04:00 PM | -- -- -- -- -- -- | | <----+-- slice 5: 04:00 to 08:00 PM | -- -- -- -- -- -- | | <----+-- slice 6: 08:00 to 12:00 PM +------------------------------------+ ---- The current week number is displayed on the top-right side of the panel (*# 13* meaning it is the 13th week of the year in the above example). The seven days of the current week are displayed in column. Each day is divided into slices of 4 hours each (6 slices in total, see figure above). A slice will appear in a different color if an appointment falls into the corresponding time-slot. In the appointment panel, one can notice the *`(|)`* sign just in front of the date. This indicates the current phase of the moon. Depending on which is the current phase, the following signs can be seen: ` |) `:: first quarter ` (|) `:: full moon ` (| `:: last quarter ` | `:: new moon no sign:: Phase of the moon does not correspond to any of the above ones. At the very bottom of the screen there is a status bar, which indicates the possible actions and the corresponding keystrokes. Just above this status bar is the notify-bar, which indicates from left to right : the current date, the current time, the calendar file currently in use (apts on the above example, which is the default calendar file, see the following section), and the next appointment within the upcoming 24 hours. Here it says that it will be lunch time in one hour and twenty minutes. NOTE: Some actions, such as editing or adding an item, require to type in some text. This is done with the help of the built-in input line editor. Within this editor, if a line is longer than the screen width, a `>`, `*`, or `<` character is displayed in the last column indicating that there are more character after, before and after, or before the current position, respectively. The line is scrolled horizontally as necessary. Moreover, some editing commands are bound to particular control characters. Hereafter are indicated the available editing commands (`^` stands for the control key): `^a`:: moves the cursor to the beginning of the input line `^b`:: moves the cursor backward `^d`:: deletes one character forward `^e`:: moves the cursor to the end of the input line `^f`:: moves the cursor forward `^h`:: deletes one character backward `^k`:: deletes the input from the cursor to the end of the line `^w`:: deletes backward to the beginning of the current word `ESCAPE`:: cancels the editing [[basics_daemon]] Background mode ~~~~~~~~~~~~~~~ When the daemon mode is enabled in the notification configuration menu (see <>), `calcurse` will stay in background when the user interface is not running. In background mode, `calcurse` checks for upcoming appointments and runs the user-defined notification command when necessary. When the user interface is started again, the daemon automatically stops. `calcurse` background activity can be logged (set the `daemon.log` variable in the notification configuration <>), and in that case, information about the daemon start and stop time, reminders' command launch time, signals received... will be written in the `daemon.log` file (see section <>). Using the `--status` command line option (see section <>), one can know if `calcurse` is currently running in background or not. If the daemon is running, a message like the following one will be displayed (the pid of the daemon process will be shown): ---- calcurse is running in background (pid 14536) ---- NOTE: To stop the daemon, just send the `TERM` signal to it, using a command such as: `kill daemon_pid`, where *daemon_pid* is the process id of the daemon (14536 in the above example). [[basics_files]] calcurse files ~~~~~~~~~~~~~~ The following structure is created in your `$HOME` directory (or in the directory you specified with the -D option) the first time `calcurse` is run : ---- $HOME/.calcurse/ |___notes/ |___conf |___keys |___apts |___todo ---- `notes/`:: this subdirectory contains descriptions of the notes which are attached to appointments, events or todos. Since the file name of each note file is a SHA1 hash of the note itself, multiple items can share the same note file. calcurse provides a garbage collector (see the `-g` command line parameter) that can be used to remove note files which are no longer linked to any item. `conf`:: this file contains the user configuration `keys`:: this file contains the user-defined key bindings `apts`:: this file contains all of the events and user's appointments `todo`:: this file contains the todo list NOTE: If the logging of calcurse daemon activity was set in the notification configuration menu, the extra file `daemon.log` will appear in calcurse data directory. This file contains logs about calcurse activity when running in background. Import/Export capabilities ~~~~~~~~~~~~~~~~~~~~~~~~~~ The import and export capabilities offered by `calcurse` are described below. Import ^^^^^^ Data in icalendar format as described in the rfc2445 specification (see <> section below) can be imported into calcurse. Calcurse ical parser is based on version 2.0 of this specification, but for now on, only a subset of it is supported. The following icalendar properties are handled by calcurse: * `VTODO` items: "PRIORITY", "VALARM", "SUMMARY", "DESCRIPTION" * `VEVENT` items: "DTSTART", "DTEND", "DURATION", "RRULE", "EXDATE", "VALARM", "SUMMARY", "DESCRIPTION" The icalendar `DESCRIPTION` property will be converted into calcurse format by adding a note to the item. If a "VALARM" property is found, the item will be flagged as important and the user will get a notification (this is only applicable to appointments). Here are the properties that are not implemented: * negative time durations are not taken into account (item is skipped) * some recurence frequences are not recognize: "SECONDLY" / "MINUTELY" / "HOURLY" * some recurrence keywords are not recognized (all those starting with `BY`): "BYSECOND" / "BYMINUTE" / "BYHOUR" / "BYDAY" / "BYMONTHDAY" / "BYYEARDAY" / "BYWEEKNO" / "BYMONTH" / "BYSETPOS" plus "WKST" * the recurrence exception keyword "EXRULE" is not recognized * timezones are not taken into account Export ^^^^^^ Two possible export formats are available: `ical` and `pcal` (see section <> below to find out about those formats). Online help ~~~~~~~~~~~ At any time, the built-in help system can be invoked by pressing the `?` key. By default, it shows an introduction to the help system in an external pager. You need to exit the pager in order to get back to calcurse (pressing `q` should almost always work). The default pager can be changed by setting the PAGER environment variable. If you want to display help on a specific feature or key binding, type `:help ` (e.g. `:help add`) or `:help ` (e.g. `:help ^A`) on the main screen. Options ------- All of the `calcurse` parameters are configurable from the Configuration menu available when pressing `C`. You are then driven to a submenu with five possible choices : pressing `C` again will lead you to the Color scheme configuration, pressing `L` allows you to choose the layout of the main `calcurse` screen (in other words, where to put the three different panels on screen), pressing `G` permits you to choose between different general options, pressing `K` opens the key bindings configuration menu, and last you can modify the notify-bar settings by pressing `N`. [[options_general]] General options ~~~~~~~~~~~~~~~ These options control `calcurse` general behavior, as described below: `appearance.compactpanels` (default: *no*):: In compact panels mode, all captions are removed from panels. `appearance.defaultpanel` (default: *calendar*):: This can be used to specify the panel to be selected on startup. `general.autosave` (default: *yes*):: This option allows to automatically save the user's data (if set to *yes*) when quitting.

warning: No data will be automatically saved if `general.autosave` is set to *no*. This means the user must press `S` (for saving) in order to retrieve its modifications. `general.autogc` (default: *no*):: Automatically run the garbage collector for note files when quitting. `general.periodicsave` (default: *0*):: If different from `0`, user's data will be automatically saved every *general.periodicsave* minutes. When an automatic save is performed, two asterisks (i.e. `**`) will appear on the top right-hand side of the screen). `general.confirmquit` (default: *yes*):: If set to *yes*, confirmation is required before quitting, otherwise pressing `Q` will cause `calcurse` to quit without prompting for user confirmation. `general.confirmdelete` (default: *yes*):: If this option is set to *yes*, pressing `D` for deleting an item (either a *todo*, *appointment*, or *event*), will lead to a prompt asking for user confirmation before removing the selected item from the list. Otherwise, no confirmation will be needed before deleting the item. `general.systemdialogs` (default: *yes*):: Setting this option to *no* will result in skipping the system dialogs related to the saving and loading of data. This can be useful to speed up the input/output processes. `general.progressbar` (default: *yes*):: If set to *no*, this will cause the disappearing of the progress bar which is usually shown when saving data to file. If set to *yes*, this bar will be displayed, together with the name of the file being saved (see section <>). `appearance.calendarview` (default: *0*):: If set to `0`, the monthly calendar view will be displayed by default otherwise it is the weekly view that will be displayed. `general.firstdayofweek` (default: *monday*):: One can choose between Monday and Sunday as the first day of the week. If `general.firstdayofweek` is set to *monday*, Monday will be first in the calendar view. Otherwise, Sunday will be the first day of the week. `format.outputdate` (default: *%D*):: This option indicates the format to be used when displaying dates in non-interactive mode. Using the default values, dates are displayed the following way: *mm/dd/aa*. You can see all of the possible formats by typing `man 3 strftime` inside a terminal. `format.inputdate` (default: *1*):: This option indicates the format that will be used to enter dates in interactive mode. Four choices are available: + 1. mm/dd/yyyy 2. dd/mm/yyyy 3. yyyy/mm/dd 4. yyyy-mm-dd [[options_keys]] Key bindings ~~~~~~~~~~~~ One can define ones own key bindings within the `Keys` configuration menu. The default keys look like the one used by the `vim` editor, especially the displacement keys. Anyway, within this configuration menu, users can redefine all of the keys available from within calcurse's user interface. To define new key bindings, first highlight the action to which it will apply. Then, delete the actual key binding if necessary, and add a new one. You will then be asked to press the key corresponding to the new binding. It is possible to define more than one key binding for a single action. An automatic check is performed to see if the new key binding is not already set for another action. In that case, you will be asked to choose a different one. Another check is done when exiting from this menu, to make sure all possible actions have a key associated with it. The following keys can be used to define bindings: * lower-case, upper-case letters and numbers, such as `a`, `Z`, `0` * CONTROL-key followed by one of the above letters * escape, horizontal tab, and space keys * arrow keys (up, down, left, and right) * `HOME` and `END` keys While inside the key configuration menu, an online help is available for each one of the available actions. This help briefly describes what the highlighted action is used for. NOTE: As of calcurse 3.0.0, displacement commands can be preceded by an optional number to repeat the command. For example, `10k` will move the cursor ten weeks forwards if you use default key bindings. Color themes ~~~~~~~~~~~~ `calcurse` color theme can be customized to suit user's needs. To change the default theme, the configuration page displays possible choices for foreground and background colors. Using arrows or calcurse displacement keys to move, and `X` or space to select a color, user can preview the theme which will be applied. It is possible to keep the terminal's default colors by selecting the corresponding choice in the list. The chosen color theme will then be applied to the panel borders, to the titles, to the keystrokes, and to general informations displayed inside status bar. A black and white theme is also available, in order to support non-color terminals. NOTE: Depending on your terminal type and on the value of the `$TERM` environment variable, color could or could not be supported. An error message will appear if you try to change colors whereas your terminal does not support this feature. If you do know your terminal supports colors but could not get `calcurse` to display them, try to set your `$TERM` variable to another value (such as *xterm-xfree86* for instance). Layout configuration ~~~~~~~~~~~~~~~~~~~~ The layout corresponds to the position of the panels inside `calcurse` screen. The default layout makes the calendar panel to be displayed on the top-right corner of the terminal, the todo panel on the bottom-right corner, while the appointment panel is displayed on the left hand-side of the screen (see the figure in section <> for an example of the default layout). By choosing another layout in the configuration screen, user can customize `calcurse` appearance to best suit his needs by placing the different panels where needed. The following option is used to modify the layout configuration: `appearance.layout` (default: *0*):: Eight different layouts are to be chosen from (see layout configuration screen for the description of the available layouts). Sidebar configuration ~~~~~~~~~~~~~~~~~~~~~ The sidebar is the part of the screen which contains two panels: the calendar and, depending on the chosen layout, either the todo list or the appointment list. The following option is used to change the width of the sidebar: `appearance.sidebarwidth` (default: *0*):: Width (in percentage, 0 being the minimum width) of the side bar. [[options_notify]] Notify-bar settings ~~~~~~~~~~~~~~~~~~~ The following options are used to modify the notify-bar behavior: `appearance.notifybar` (default: *yes*):: This option indicates if you want the notify-bar to be displayed or not. `format.notifydate` (default: *%a %F*):: With this option, you can specify the format to be used to display the current date inside the notification bar. You can see all of the possible formats by typing `man 3 strftime` inside a terminal. `format.notifytime` (default: *%T*):: With this option, you can specify the format to be used to display the current time inside the notification bar. You can see all of the possible formats by typing `man 3 strftime` inside a terminal. `notification.warning` (default: *300*):: When there is an appointment which is flagged as `important` within the next `notification.warning` seconds, the display of that appointment inside the notify-bar starts to blink. Moreover, the command defined by the `notification.command` option will be launched. That way, the user is warned and knows there will be soon an upcoming appointment. `notification.command` (default: *printf '\a'*):: This option indicates which command is to be launched when there is an upcoming appointment flagged as `important`. This command will be passed to the user's shell which will interpret it. To know what shell must be used, the content of the `$SHELL` environment variable is used. If this variable is not set, `/bin/sh` is used instead. + ==== Say the `mail` command is available on the user's system, one can use the following command to get notified by mail of an upcoming appointment (the appointment description will also be mentioned in the mail body): ---- $ calcurse --next | mail -s "[calcurse] upcoming appointment!" user@host.com ---- ==== `notification.notifyall` (default: *flagged-only*):: If set to flagged-only, you are only notified of flagged items. If set to unflagged-only, you are only notified of unflagged items. If set to all, notifications are always sent, independent of whether an item is flagged or not. For historical reasons, this option also accepts boolean values where yes equals flagged-only and no equals unflagged-only. `daemon.enable` (default: *no*):: If set to yes, daemon mode will be enabled, meaning `calcurse` will run into background when the user's interface is exited. This will allow the notifications to be launched even when the interface is not running. More details can be found in section <>. `daemon.log` (default: *no*):: If set to yes, `calcurse` daemon activity will be logged (see section <>). Known bugs ---------- Incorrect highlighting of items appear when using calcurse black and white theme together with a `$TERM` variable set to *xterm-color*. To fix this bug, and as advised by Thomas E. Dickey (`xterm` maintainer), *xterm-xfree86* should be used instead of *xterm-color* to set the `$TERM` variable: ____ "The xterm-color value for $TERM is a bad choice for XFree86 xterm because it is commonly used for a `terminfo` entry which happens to not support bce. Use the xterm-xfree86 entry which is distributed with XFree86 xterm (or the similar one distributed with ncurses)." ____ [[bugs]] Reporting bugs and feedback --------------------------- Please send bug reports and feedback to: `misc .at. calcurse .dot. org`. [[contribute]] How to contribute? ------------------ If you would like to contribute to the project, you can first send your feedback on what you like or dislike, and if there are features you miss in `calcurse`. For now on, possible contributions concern the translation of `calcurse` messages and documentation. Translating documentation ~~~~~~~~~~~~~~~~~~~~~~~~~ NOTE: We recently dropped all translations of the manual files from the distribution tarball. There are plan to reintroduce them in form of a Wiki on the calcurse website. Please follow the mailing lists for up-to-date information. The *doc/* directory of the source package already contains translated version of `calcurse` manual. However, if the manual is not yet available into your native language, it would be appreciated if you could help translating it. To do so, just copy one of the existing manual file to `manual_XX.html`, where *XX* identifies your language. Then translate this newly created file and send it to the author (see <>), so that it can be included in the next `calcurse` release. calcurse i18n ~~~~~~~~~~~~~ As already mentioned, `gettext` utilities are used by `calcurse` to produce multi-lingual messages. We are currently using http://www.transifex.net/[Transifex] to manage those translations. This section provides informations about how to translate those messages into your native language. However, this howto is deliberately incomplete, focusing on working with `gettext` for `calcurse` specifically. For more comprehensive informations or to grasp the Big Picture of Native Language Support, you should refer to the `GNU gettext` manual at: http://www.gnu.org/software/gettext/manual/ IMPORTANT: Since we switched to Transifex, editing *po* files is not necessary anymore as Transifex provides a user-friendly, intuitive web interface for translators. Knowledge of `gettext` and the *po* format is still useful for those of you who prefer the command line and local editing. If you want to use the web UI to edit the translation strings, you can skip over to <> tough. Basically, three different people get involved in the translation chain: coders, language coordinator, and translators. After a quick overview of how things work, the translator tasks will be described hereafter. Overview ^^^^^^^^ To be able to display texts in the native language of the user, two steps are required: *internationalization* (i18n) and *localization* (l10n). i18n is about making `calcurse` support multiple languages. It is performed by coders, who will mark translatable texts and provide a way to display them translated at runtime. l10n is about making the i18n'ed `calcurse` adapt to the specific language of the user, ie translating the strings previously marked by the developers, and setting the environment correctly for `calcurse` to use the result of this translation. So, translatable strings are first marked by the coders within the `C` source files, then gathered in a template file (*calcurse.pot* - the *pot* extension meaning *portable object template*). The content of this template file is then merged with the translation files for each language (*fr.po* for French, for instance - with *po* standing for *portable object*, ie meant to be read and edited by humans). A given translation team will take this file, translate its strings, and send it back to the developers. At compilation time, a binary version of this file (for efficiency reasons) will be produced (*fr.mo* - *mo* stands for *machine object*, i.e. meant to be read by programs), and then installed. Then `calcurse` will use this file at runtime, translating the strings according to the locale settings of the user. Translator tasks ^^^^^^^^^^^^^^^^ Suppose someone wants to initiate the translation of a new language. Here are the steps to follow: * First, find out what the locale name is. For instance, for french, it is `fr_FR`, or simply `fr`. This is the value the user will have to put in his `LC_ALL` environment variable for software to be translated (see <>). * Then, go into the *po/* directory, and create a new po-file from the template file using the following command: `msginit -i calcurse.pot -o fr.po -l fr --no-translator` If you do not have `msginit` installed on your system, simply copy the *calcurse.pot* file to *fr.po* and edit the header by hand. Now, having this *fr.po* file, the translator is ready to begin. po-files ^^^^^^^^ The format of the po-files is quite simple. Indeed, po-files are made of four things: 1. *location lines:* tells you where the strings can be seen (name of file and line number), in case you need to see a bit of context. 2. *msgid lines:* the strings to translate. 3. *msgstr lines:* the translated strings. 4. *lines prefixed with `#`:* comments (some with a special meaning, as we will see below). Basically, all you have to do is fill the *msgstr* lines with the translation of the above *msgid* line. A few notes: *Fuzzy strings*:: You will meet strings marked with a `"#, fuzzy"` comment. `calcurse` won't use the translations of such strings until you do something about them. A string being fuzzy means either that the string has already been translated but has since been changed in the sources of the program, or that this is a new string for which `gettext` made a 'wild guess' for the translation, based on other strings in the file. It means you have to review the translation. Sometimes, the original string has changed just because a typo has been fixed. In this case, you won't have to change anything. But sometimes, the translation will no longer be accurate and needs to be changed. Once you are done and happy with the translation, just remove the `"#, fuzzy"` line, and the translation will be used again in `calcurse`. *c-format strings and special sequences*:: Some strings have the following comment: `"#, c-format"`. This tells that parts of the string to translate have a special meaning for the program, and that you should leave them alone. For instance, %-sequences, like `"%s"`. These means that `calcurse` will replace them with another string. So it is important it remains. There are also \-sequences, like `\n` or `\t`. Leave them, too. The former represents an end of line, the latter a tabulation. *Translations can be wrapped*:: If lines are too long, you can just break them like this: + ---- msgid "" "some very long line" "another line" ---- *po-file header*:: At the very beginning of the po-file, the first string form a header, where various kind of information has to be filled in. Most important one is the charset. It should resemble + ---- "Content-Type: text/plain; charset=utf-8\n" ---- + You should also fill in the Last-Translator field, so that potential contributors can contact you if they want to join you in the translation team, or have remarks/typo fixes to give about the translations. You can either just give your name/nick, or add an email address, for exemple: + ---- "Last-Translator: Frederic Culot \n" ---- *Comments*:: Adding comments (lines begining with the `#` character) can be a good way to point out problems or translation difficulties to proofreaders or other members of your team. *Strings size*:: `calcurse` is a curses/console program, thus it can be heavily dependant on the terminal size (number of columns). You should think about this when translating. Often, a string must fit into a single line (standard length is 80 characters). Don't translate blindly, try to look where your string will be displayed to adapt your translation. *A few useful tools*:: The po-file format is very simple, and the file can be edited with a standard text editor. But if you prefer, there are few specialized tools you may find convenient for translating: + * `poEdit` (http://www.poedit.org/) * `KBabel` (http://i18n.kde.org/tools/kbabel/) * `GTranslator` (http://gtranslator.sourceforge.net/) * `Emacs` po mode * `Vim` po mode *And finally*:: I hope you'll have fun contributing to a more internationalized world. :) If you have any more questions, don't hesitate to contact us at *misc .at. calcurse .dot. org*. [[transifex_uploading]] Uploading to Transifex ^^^^^^^^^^^^^^^^^^^^^^ There's several different ways to upload a finished (or semi-finished) translation for a new language to Transifex. The easiest way is to browse to the http://www.transifex.net/projects/p/calcurse/teams/[Translation Teams] page and request the addition of a new team. As soon as we accepted your request, you will be able to upload your *po* file on the http://www.transifex.net/projects/p/calcurse/resource/calcursepot/[calcurse resource page] by clicking the *Add translation* button at the bottom. Using transifex-client ^^^^^^^^^^^^^^^^^^^^^^ You can also use a command line client to submit translations instead of having to use the web interface every time you want to submit an updated version. If you have a recent version of `setuptools` installed, you can get the CLI client by issuing the following command: ---- $ easy_install -U transifex-client ---- Alternatively, you can get the source code of transifex-client at http://pypi.python.org/pypi/transifex-client. After you downloaded and installed the client, run the following commands in the calcurse source directory to checkout the translation resources of *calcurse*: ---- $ tx pull -a ---- To submit changes back to the server, use: ---- $ tx push -r calcurse.calcursepot -t -l ---- For more details, read up on `transifex-client` usage at the http://help.transifex.net/user-guide/client/[The Transifex Command-line Client v0.4] section of the http://help.transifex.net/[Transifex documentation]. [[transifex_webui]] Using the Transifex web UI ^^^^^^^^^^^^^^^^^^^^^^^^^^ As an alternative to editing *po* files, there is a web-based interface that can be used to create and update translations. After having signed up and created a new translation team (see <> on how to do that), click the *Add translation* button at the bottom on the http://www.transifex.net/projects/p/calcurse/resource/calcursepot/[calcurse resource page], select the language you'd like to translate and choose *Translate Online*.
