* System message queueLars Henriksen2018-10-211-0/+1
| | | | | | | | | | | | | | | The screen and user interaction is managed by the main thread. Other parts of calcurse (threads) wishing to use the screen or communicate with the user, must do it via the main thread. For this purpose the main input loop is extended with a message queue. A thread may insert a message in the queue. The main thread tests for messages before listening for user commands. If a message is present, it is displayed (in a popup window) for the user to acknowledge. Depending on the message other actions may be performed, e.g. the message could be turned into a "system appointment/event" and inserted among the usual appointments.

* Implement utility functions for dynamic stringsLukas Fleischer2016-01-131-0/+1
| | | | | | | | Introduce support for strings which support concatenating the current value with a printf-style formatted value, thereby growing in size dynamically. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add pre-save and post-save hooksLukas Fleischer2016-01-071-0/+1
| | | | | | | | | | | | | This adds support for hooks which are executed before/after saving calcurse data. Hooks can be placed under hooks/pre-save and hooks/post-save in the data directory and need to be executable. Potential use cases include: * Automatically commit any changes to the data files using a VCS. * Automatically sync with some sever component on data file changes.

* Add a generic list box implementationLukas Fleischer2014-05-181-0/+1
| | | | | | | | This adds a very generic list box implementation. List boxes with items of different heights are supported. Two callback functions to determine the height of every single item and to draw a specific item are used. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Split online help code into a separate functionLukas Fleischer2013-07-181-0/+1
| | | | | | | Reintroduce help.c and move the online help code into a new function display_help(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Drop legacy online help systemLukas Fleischer2013-07-171-1/+0
| | | | | | | | | | Remove the old online help system and change the generic help key to do the same thing as ":help". This also removes some context-sensitive help. We should think about re-adding support for this later. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add help commandLukas Fleischer2013-07-171-0/+1
| | | | | | | | | This adds a "help" command to the list of available command mode commands. You can currently type "help", followed by a topic like "add". calcurse will then try to open a file named "add.txt" in the documentation directory and display it in an external pager.

* calendar.c: Rename to "ui-calendar.c"Lukas Fleischer2013-02-141-1/+1
| | | | | | | | | 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>
* Rename appointment/event-related UI functionsLukas Fleischer2013-02-141-1/+1
| | | | | | | | | * Rename "interaction.c" to "ui-day.c" since it no longer contains todo-related UI functions. * Rename appointment/event-related UI functions to ui_day_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Split out UI functions for todo itemsLukas Fleischer2013-02-141-0/+1
| | | | | | | | | * Move todo-related UI functions from "interaction.c" to a new compilation unit "ui-todo.c". * Rename all todo-related UI functions to todo_ui_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Move interaction functions to a separate fileLukas Fleischer2012-06-301-0/+1
| | | | | | | | | | | | | | | This is a first step to clean up several compilation units and separate the front end from back-end operations. All functions that require user interaction are moved to a new compilation unit "interaction.c". Also, following things are adjusted to the new layout: * Make day_item_get_*() and a few other functions public, so that it can be accessed from the new compilation unit. * Use apoint_hilt(), todo_hilt(), etc. instead of directly accessing static variables. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* {src,test}/Makefile.am: Enable pedantic warningsLukas Fleischer2012-02-191-0/+2
| | | | | | | | Now that we're fully POSIX compliant and fixed up some minor issues with ISO C99, use "-std=c99 -pedantic -D_POSIX_C_SOURCE=200809L" as default build flags for calcurse and the test suite. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Break out different import/export formatsLukas Fleischer2012-01-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | Extract iCal and pcal import/export routines into separate files. This reduces complexity of the super huge "io.c" source file and makes it easier to follow changes that affect the iCal and pcal routines only (commits affecting both formats are very uncommon). Before: $ wc -l src/io.c 2938 src/io.c After: $ wc -l src/{io,ical,pcal}.c 1445 src/io.c 1263 src/ical.c 317 src/pcal.c 3025 total Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Extract config file handlers into a separate fileLukas Fleischer2011-12-091-0/+1
| | | | | | | | We used custom_load_conf() to load the configuration file and io_save_conf() to save configuration. Move these functions, including all helpers, to a central location. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add a SHA1 implementationLukas Fleischer2011-10-051-0/+2
| | | | | | | | | | | | | | | | | | Add an implementation of the SHA1 hash algorithm based on a public domain project by Steve Reid <sreid@sea-to-sky.net>. You can get the original sources from: ftp://ftp.funet.fi/pub/crypt/hash/sha/sha1.c We will need this for several things. File names of note files will be generated based on a hash their content instead of using a random name. Items can be uniquely identified using a hash. In addition to the regular sha1_init(), sha1_update() and sha1_final() operations, our implementation also contains wrappers for hashing a string or a stream.

* Refactor out note functionsLukas Fleischer2011-07-211-0/+1
| | | | | | | | | | * Add new note_edit() and note_view() helper functions. Use these instead of copy-pasted code in *_note_edit(). * Move all note-related functions (note_edit(), note_view(), note_erase()) to a new source file "note.c". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Split line editing functions into separate fileLukas Fleischer2011-06-291-0/+1
| | | | | | | Move getstring() related stuff into a separate file as a first step on our way to UTF-8 support for line editing helpers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add basic UTF-8 helper functionsLukas Fleischer2011-06-291-0/+1
| | | | | | | | | | Add utf8_width() and utf8_strwidth() which can be used to calculate the display width of a single character or a string, respectively. A lookup table is used to spot double width characters, as well as composing characters. There currently isn't any code to deal with ambigious characters.

* Add missing llist header files to "_SOURCES".Lukas Fleischer2011-05-171-0/+2
| | | | | | | | We forgot to add those to the "_SOURCES" variable in commit 0eb1da8dd7fa3ae9d95e12df6058fb41a5ec1c11 and d668963e2056027526374098efe2869a0d389b92. Spotted by `make distcheck`. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add linked lists implementation.Lukas Fleischer2011-04-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed on the mailing lists, the various linked list implementations we currently use at a dozen of different places in the calcurse source tree are inconvenient and should be replaced by a single generic solution. This is a first approach to introduce such a generic implemetation. It provides following functions: * llist_init(): Initialize a list. * llist_free_inner(): Loop through a list and free all items. * llist_free(): Free the list itself (but not the individual items). * llist_first(): Get the first item of a list. * llist_nth(): Get the nth item of a list. * llist_next(): Get the successor of a list item. * llist_find_first(): Find an item using a callback function. * llist_find_next(): Find the next match using a callback function. * llist_find_nth(): Find the nth item in a list (using a callback). * llist_get_data(): Get a pointer to the actual data of a list item. * llist_add(): Add an item at the end of a list. * llist_add_sorted(): Add an item to a sorted list (using a comparison callback function). * llist_remove(): Remove an item from a list. Linked lists are stored in "llist_t" structures, list items are to be stored in "llist_item_t" structs. All of the llist_*() functions either expect a pointer to a llist_t structure (in case the function operates on the list itself) or a pointer to a llist_item_t (llist_*_next() and llist_get_data()).
