* Make the text for empty days configurableLars Henriksen2019-11-031-0/+1
| | | | | | | The default is "--"; a single space makes the text invisible. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Automate the calculation of number of days to loadLars Henriksen2019-05-261-1/+1
| | | | | | | | | | | | Instead of having the user tell how many days to load, calcurse can calculate an overestimation from the running configuration (panel size, appearance of headers and separators etc.) The configuration variable conf.multiple_days is turned into a Boolean that switches the feature on and off.

* Make separation of days conspicuousLars Henriksen2019-05-261-1/+3
| | | | | | | | | | | | | | | ... by adding a horizontal line from border to border above the day heading and turning the event separator into an empty line. The horizontal line is left out for the first day loaded. Also reduce the number of empty lines at the end of a day to at most one. A new configuration variable, header_line, turns the horizontal line on and off. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add configuration variables for multiple daysLars Henriksen2019-05-221-0/+3
| | | | | | | | | | | | | | | The number of days displayed in the APP panel has been made configurable, maximum 21 days, default seven days. With several days in the APP panel, it may be desirable to "squeeze" the entries by leaving out the final empty line of each appointment and lower the number of lines between consecutive days (0, 1, or 2). Both are made general configuration options. To make a uniform display, an empty line is added to a day without appointments, if appointments have an empty line.

* Avoid deadlock in config_save()Lars Henriksen2019-03-211-7/+8
| | | | | | | | | Must not exit with nbar.mutex locked. Addresses GitHub issue #201. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Explicit calendar and todo view configurationLars Henriksen2019-01-071-8/+12
| | | | | | | | | | | | | | | | | | | The configuration settings for calendar view (monthly/weekly) and todo view (hide/show completed) used to be saved automatically on calcurse exit, with values taken from the current interactive settings. They could not be set explicitly in the configuration menues. Configuration settings are no longer saved on program exit, but on exit from the configuration menu. This means that the saved values are those that were current when the configuration menu was entered. To change a saved value, you must set the view as desired and then enter/exit the configuration menu. The preferred calendar and todo views are no longer automatically taken from the interactive settings, but are explicitly set in the general options menu. Default values are monthly view and hide completed view. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* CLI: take input date format from configuration file, do not accept timeLars Henriksen2019-01-071-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch the input date parsing accepts three formats: yyyy/mm/dd, mm/dd/yyyy, yyyy-mm-dd. They are tried in sequence. It also accepts an additional time (hh:mm), or a time without a date. There are several issues with this: - it is not documented - the date format dd/mm/yyyy is not accepted - print_date() and filter option settings (in parse_args()) can only handle midnight times (which are the result of a date without time) - it is highly uncertain what happens if a time (without a date) is given; at least the -d option treats a time without colon (1215 for 12:15) as a number It seems that acceptance of time input is a by-product and not needed. For these reasons the input date parsing has been changed: - the format is taken from the configuration file (as is the case for the output date format) - only a date, and no time, is accepted Because the input date format is used during parsing of the command line, the configuration file must be loaded first, i.e. the options -D or -C must be parsed before the remaining ones. Loading the configuration file may result in errors (e.g. caused by changes between versions). For this reason config_load() has been made more tolerant and issues warnings instead of exiting. A followup patch will introduce two options to allow the configuration file settings to be overridden for input and output date formats.

* Configuration variable for system eventsLars Henriksen2018-10-211-0/+1
| | | | | | | | After user acknowledgement a system event is deleted from the event queue. The configuration variable determines whether it is turned into an appointment (for later inspection) or not. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Remove the configuraton variable conf.progress_barLars Henriksen2018-10-211-1/+6
| | | | | | | | When loading/saving the configuration file the entry is silently ignored (which means it is removed by the first save). Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Avoid buffer overrun in config_parse_str()Lukas Fleischer2018-05-261-1/+6
| | | | | | | | | | The previous implementation only read a prefix from the configuration file if the configuration value was too long and forgot to terminate the string with a NUL character. Return 0 if the string is too long instead. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Default colour as foreground colourLars Henriksen2017-12-101-0/+1
| | | | | | | | | | | | | In the default colour setup (white on black), white could only with great difficulty be used as customized foreground colour, because the colour pair COLR_CUSTOM then was identical to COLR_DEFAULT (default on default). This made it impossible to distinguish the selected element in lists. The patch turns on the video attribute bold when default is chosen as foreground colour.

* Make the day heading position configurableLars Henriksen2017-09-081-0/+27
| | | | | | | | | The date at the top of the appointments list may be positioned either to the left, in the middle or to the right. Default is to the right. Can be configured from the general options menu. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make heading in appointments panel configurableLars Henriksen2017-08-281-0/+1

* Support sending notifications for all appointmentsLukas Fleischer2016-01-271-1/+29
| | | | | | | | | | In 45417bc (Add configuration option to notify all appointments, 2011-07-31), we added an option that allows for choosing whether the user receives notifications only for flagged or only for unflagged appointments. Convert this setting into a three-state option and allow the user to additionally enable notifications for *all* appointments. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Save active view on the todo panelLukas Fleischer2016-01-181-0/+25

* Retain comments in descriptions and config valuesLukas Fleischer2014-08-181-1/+3
| | | | | | | | | Comments should only be stripped if they start at the beginning of a line. We do not want to chop off an TODO item description or a configuration value. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* config.c: Rework configuration serializationLukas Fleischer2014-07-221-66/+58

* Refactor new_tempfile()Lukas Fleischer2014-07-221-11/+11
| | | | | | | | Avoid preallocating buffers on the stack, use dynamic memory allocation instead. Also, change the semantics of new_tempfile() so that it returns the full name of the temporary file and fix all call sites. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Replace several uses of snprintf() by asprintf()Lukas Fleischer2014-07-221-2/+1
| | | | | | | | Use asprintf() in some cold code paths. While allocating memory on the heap is a bit slower, using asprintf() is a bit more memory efficient and less prone to buffer overflow errors. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Use a macro to determine the size of arraysLukas Fleischer2013-05-041-4/+4
| | | | | | | | Use following macro instead of "sizeof(x) / sizeof(x[0])" everywhere: #define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0])) Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use tabs instead of spaces for indentationLukas Fleischer2013-04-141-346/+352
| | | | | | | | | | | This completes our switch to the Linux kernel coding style. Note that we still use deeply nested constructs at some places which need to be fixed up later. Converted using the `Lindent` script from the Linux kernel code base, along with some manual fixes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix braces in if-else statementsLukas Fleischer2013-02-171-17/+20
| | | | | | | | | | From the Linux kernel coding guidelines: Do not unnecessarily use braces where a single statement will do. [...] This does not apply if one branch of a conditional statement is a single statement. Use braces in both branches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* calendar.c: Rename to "ui-calendar.c"Lukas Fleischer2013-02-141-6/+6
| | | | | | | | | This unit belongs to the presentation layer -- rename the file accordingly. Also, rename calendar_*() to ui_calendar_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Update copyright rangesLukas Fleischer2013-02-041-1/+1

* Add compact panels supportLukas Fleischer2012-11-251-0/+1
| | | | | | | | | | | | | Add a configuration option that allows for switching to compact panel mode. In this mode, all window labels are hidden, so that there's more space for actual information. This patch doesn't add a configuration menu entry and doesn't add any documentation. Implements FR#7. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add configuration option to set a default panelLukas Fleischer2012-11-251-0/+30
| | | | | | | | | | | | | This allows for customizing the panel that is selected by default when calcurse is started. Note that this patch doesn't add any documentation. Also, this configuration option currently cannot be configured using the configuration menu. Implements FR#19. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Fix parsing an unset color themeLukas Fleischer2012-06-301-1/+5
| | | | | | | | | If color support is disabled, the color theme configuration value is set to "0" or "none", which is a value we no longer accepted since commit a5486605696f92a749277d49c77bb5b194dc67a5. Re-introduce the branch that checks for an unset color theme before actually parsing it. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Make appearance.calendarview more explicit in config fileBaptiste Jonglez2012-05-311-3/+13
| | | | | | | | | | Instead of using 0 or 1 as a value for `appearance.calendarview`, introduce the more explicit "monthly" and "weekly". Also update `scripts/calcurse-upgrade.sh` to reflect the change. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Give a meaning to DATE_FORMATSBaptiste Jonglez2012-05-311-1/+1
| | | | | | | | | | | It's a bit weird to consider DATE_FORMATS as part of the date input format enum, all the more so as it does not even represent the number of available formats (since those are numbered from 1). Turn DATE_FORMATS into the number of available date input formats. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Bail out on incomplete directiveLukas Fleischer2012-05-291-0/+3
| | | | | | | | | | Fixes a segmentation fault that arose if a line in the configuration file didn't contain a value/key separator ("="). Instead of operating on a NULL pointer, throw an error message containing the erroneous directive and bail out.

* Switch to Linux kernel coding styleLukas Fleischer2012-05-211-298/+256
| | | | | | | | | | | | | | Convert our code base to adhere to Linux kernel coding style using Lindent, with the following exceptions: * Use spaces, instead of tabs, for indentation. * Use 2-character indentations (instead of 8 characters). Rationale: We currently have too much levels of indentation. Using 8-character tabs would make huge code parts unreadable. These need to be cleaned up before we can switch to 8 characters. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix data type of "general.firstdayofweek"Lukas Fleischer2012-05-171-10/+12
| | | | | | | | | | | This option wasn't converted to a proper data type when it was renamed from "week_begins_on_monday" to "general.firstdayofweek". Convert the boolean option into an enumeration type that can take the values "monday" and "sunday". Also, update the documentation, add a conversion rule to the upgrade script and convert the configuration file used in the test suite. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Declare several parameters/variables constantLukas Fleischer2012-05-081-3/+3
| | | | | | | | | | | | Add the "const" keyword to parameters and variables that are never modified. Most of these were spotted by "-Wwrite-strings". We cast the second parameter to execvp() explicitly as it expects a "char *const[]" where it should expect a "const char *const[]" (according to the documentation, this is due to compatibility reasons). This should be changed once we come up with a better solution. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Mark several functions staticLukas Fleischer2012-04-201-1/+1
| | | | | | | These are not needed outside of the corresponding compilation units. Spotted with "-Wmissing-prototypes". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix semantics of "general."{systemdialogs,progressbar}Lukas Fleischer2012-03-291-2/+2
| | | | | | | | | These were renamed from "skip_"* to *. However, we only changed syntax and didn't invert their semantic meaning. Fix this by negating the semantics of those variables. Also, negate these in the configuration file automatically when running `calcurse-upgrade`. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Detect legacy configuration filesLukas Fleischer2012-03-291-0/+27
| | | | | | | | | Check configuration variable names against a list of pre-3.0.0 configuration keys and display a warning if such a variable is found. This reduces the chance of users going wild due to the non-backwards compatible configuration file changes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Reorder configuration variablesLukas Fleischer2012-03-291-15/+15
| | | | | | | Sort configuration variables lexicographically. This makes changes easier to locate. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Rename configuration variablesLukas Fleischer2012-03-271-22/+22
| | | | | | | | | | Classify configuration options into different sections. Use consistent names and formatting. This was discussed on the mailing lists. A script that updates configuration files will come in following patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Update copyright rangesLukas Fleischer2012-03-261-1/+1

* Use strcmp() instead of strncmp()Lukas Fleischer2012-03-121-2/+2
| | | | | | | | | strncmp() isn't intended to be a secure strcmp() replacement, it is designed to be used if you want to compare the first n characters of two strings. Since we always compare character pointers with string literals, switch to using strcmp() everywhere. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add a read-only optionLukas Fleischer2012-02-241-9/+4
| | | | | | | We don't save any configuration nor items if this is set. This should be used with care, and hence there's no short option for this. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix up strncat() usageLukas Fleischer2012-02-181-2/+2
| | | | | | | | | | | | | | | The last argument to strncat() should not be the total buffer length; it should be the space remaining: The strncat() function shall append not more than n bytes (a null byte and bytes that follow it are not appended) from the array pointed to by s2 to the end of the string pointed to by s1. The initial byte of s2 overwrites the null byte at the end of s1. A terminating null byte is always appended to the result. This patch fixes a couple of potential buffer overflow vulnerabilities. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Add missing configuration variablesLukas Fleischer2012-02-171-15/+42
| | | | | | | Append missing configuration variables to the end of our configuration file instead of keeping them undefined. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Revamp configuration file parsingLukas Fleischer2012-02-171-130/+81
| | | | | | | | | | | | | | | | | | | | | Reintroduce a map for configuration variable parsing. We use a different approach this time: Each map entry contains * a key, * a callback that can be used to parse that variable, * a callback that can be used to serialize that variable and * a target buffer that the parsed value is written to/read from. Commits 4f4891bdb88410ae04225f3d6acfa31d73a3901a and 6377582841118688aee13aff98c9216403582e45 show that we are pretty undecided on using a map or not. However, now that we use parser and serialization wrappers for every variable, having a central map makes everything much cleaner. The runtimes of config_load() and config_save() are slightly increased (by a constant factor). This will also allow us for implementing proper detection of missing configuration variables in the configuration file. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Add more parser/serialization wrappersLukas Fleischer2012-02-171-67/+133
| | | | | | | | | | | | Add convenience parser/serialization wrappers for all configuration variables that don't use the default config_parse_*() and config_serialize_*() helpers yet. This is nothing but a dirty hack and should be refactored later (e.g. by separating configuration variable parsing and validation or by adding optional validation functions). It makes it easier to switch to a more generic configuration parser, though. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
