2016-10-14Prevent segfault when all todo items are hiddenLukas Fleischer
To prevent from illegal memory access, we checked whether the list of todo items is empty before performing an interactive todo item action such as flagging or removal. However, since 1a4bf2b (Add a "hide completed" view to the todo panel, 2016-01-17), it is possible to hide completed items from the todo panel. Thus, it may occur that the todo list box is empty while the list of todo items is not. To detect such situations as well, teach todo_get_item() to return NULL if the requested item does not exist. Then, instead of checking whether the todo item list is non-empty, make sure that the item returned by todo_get_item() is non-NULL when performing an action.

2016-01-27Display priority todo items above regular itemsLukas Fleischer
We now support todo items with undefined priority and currently display them above todo items with a strictly positive priority. Change this and always list items with a priority greater than zero first. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-01-18Make automatic selection of todo items smarterLukas Fleischer
* Automatically focus new todo items after adding them to the list. * Keep selection when an item is moved (e.g. by changing its priority). * Focus the next item in the list when an item is removed. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-01-18Improve ordering of todo itemsLukas Fleischer
* Show uncompleted items first. * Order uncompleted and completed items by priority. * Order items with the same priority alphabetically. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-01-18Use a separate field for the completed statusLukas Fleischer
Add a new field that indicates whether a todo item is completed or not instead of encoding completed todo items by negative priorities. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-01-18Add a "hide completed" view to the todo panelLukas Fleischer
Add a second view to the todo panel that hides all completed items. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-01-13Add long format specifiers "raw" and "hash"Lukas Fleischer
Add new format specifiers to print the raw item representation or an object's hash value. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-01-13Implement {apoint,event,todo}_tostr()Lukas Fleischer
Add functions to serialize non-recurrent objects without immediately writing them to stdout. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

2014-05-18ui-todo: Large-scale refactoringLukas Fleischer
This is a complete overhaul of the TODO list user interface. The new implementation uses the generic list box panel. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2013-04-14Use tabs instead of spaces for indentationLukas Fleischer
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>
2013-02-14Mark todo_get_position() publicLukas Fleischer
This is needed in "ui-todo.c" now. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2013-02-14todo.c: Split out UI-related functionsLukas Fleischer
* Move UI-related functions to "ui-todo.c". * Rename UI-related functions to ui_todo_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2013-02-04Update copyright rangesLukas Fleischer
Add 2013 to the copyright range for all source and documentation files. Reported-by: Frederic Culot <frederic@culot.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-25Add compact panels supportLukas Fleischer
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>
2012-11-25Avoid core dump if window is too smallLukas Fleischer
Avoid setting the maximum number of items to a negative number (which eventually results in a core dump). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-18Refactor todo_chg_priority()Lukas Fleischer
Instead of passing a key, pass the number of steps to increase the priority by. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-07-10Use integers rather than floats everywhereLukas Fleischer
We don't need floating point precision if results are casted back to integer. Instead, rearrange operations and do the integer division after the multiplication. Version numbers are terminating decimals anyway and can be stored using two integers without losing any information. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-07-04Revise todo_delete_note_bynum()Lukas Fleischer
Pass an item instead of passing a list item index (analogous to commit 02c90ba53a658686bad5cb5f88c555d9eef06399). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Make *_free() publicLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Add an item parameter to various todo_*() functionsLukas Fleischer
These functions operate on arbitrary items. Pull out the code that gets the currently selected item, get the current selection when one of the functions is called and pass it as a parameter. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Revise *_delete{,_bynum}()Lukas Fleischer
Always pass an item instead of passing a date and a index. This makes use of the NULL callback that was added with one of the previous patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Move interaction functions to a separate fileLukas Fleischer
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>
2012-05-21Switch to Linux kernel coding styleLukas Fleischer
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>
2012-05-16Allow passing additional parameters to shell_exec()Lukas Fleischer
This allows for specifying multiple command line parameters to be passed on to the command in a way similar to fork_exec(). This is useful if we want to wrap editor or pager invocations in a shell. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-05-14Factorize boolean user prompting.Baptiste Jonglez
Introduce a new `status_ask_bool()` function, and use it where applicable. This greatly reduces code duplication, and will allow handling special events (resize, user escape) much more uniformely. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-05-14Use status_ask_choice() where applicableBaptiste Jonglez
These cases make obvious candidates for factorisation. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-05-08Declare several parameters/variables constantLukas Fleischer
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>
2012-04-20Mark several functions staticLukas Fleischer
These are not needed outside of the corresponding compilation units. Spotted with "-Wmissing-prototypes". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

2012-04-05Mark localized string literals constantLukas Fleischer
Translated strings returned by gettext() are statically allocated and shouldn't be modified. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

2011-12-09src/todo.c: Remove several unneeded variablesLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-11-14Use a global configuration variableLukas Fleischer
This is one of the few valid use cases for a global variable. No need to make it pseudo-local and pass it from one function to another. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-11-02Remove parentheses from return statementsLukas Fleischer
No reason to use "return (x);" here. Refer to the GNU coding guidelines for details. Created using following semantic patch: @@ expression expr; @@ - return (expr); + return expr; Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-11-02Do not cast unused return values to voidLukas Fleischer
A small style fix that removes all remaining "(void)" casts. Using these isn't encouraged in GNU coding guidelines and doesn't serve a certain purpose, except for satisfying a few static code analysis tools. We already nuked some of these in previous patches, but this semantic patch should fix what's left: @@ identifier func; @@ - (void)func ( + func ( ...); Long lines were re-formatted manually. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-11-02Avoid use of printf()/fprintf()Lukas Fleischer
Use one of the following functions where appropriate: * puts() (whenever we print hard coded strings to stdout) * fputs() (whenever we print hard coded strings to a stream) * putchar() (whenever we print a single character to stdout) * fputc() (whenever we print a single character to a stream) * strncpy() (whenever we copy hard coded strings to a buffer) This removes the overhead introduced by the format string parser and reduces the number of false positive C-format strings spotted by xgettext(1)'s heuristics. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06Add count parameter to *_{in,de}crease()Lukas Fleischer
This allows for moving more than one item up/down. This currently isn't used anywhere but will be bound to a key with one of the following patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06Remove temporary highlight pointersLukas Fleischer
Add an additional check to apoint_update_panel() and todo_update_panel() and only highlight currently selected items if the corresponding panel is active. This allows us to remove all the highlight pointer juggling that we used whenever the panel selection changed. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-05Do not unlink() note files on note removalLukas Fleischer
Now that we use hash-based note file names, note files should never be unlinked as a note file might be shared. Also, remove the ERASE_FORCE_KEEP_NOTE flag that no longer makes any sense. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-05Accept variable length note namesLukas Fleischer
Read up to the first blank in note_read() instead of assuming a fixed-width note file name. Accept everything up to 40 characters (which is the length of a SHA1 hash in hexadecimal representation). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-21Refactor out note functionsLukas Fleischer
* 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>
2011-07-05Add todo_pipe_item() functionLukas Fleischer
Pipe a serialized todo item to an external process, similar to what day_pipe_item() does (cf. c3f532d814e555abf67efb136491956428f19965). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Refactor out todo item serializationLukas Fleischer
Add a todo_write() function that allows one to serialize todo items and write serialized data to an output stream in a fashion similar to apoint_write() and event_write(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Use constant for maximum UTF-8 character sizeLukas Fleischer
Introduce a UTF8_MAXLEN constant instead of using the literal value "6" at various places. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

2011-04-22Update copyright notices in source files, documentation and "COPYING".Lukas Fleischer
* Update copyright dates (use 2004-2011 as date range everywhere). * Change copyright holder from "Frederic Culot" to "calcurse Development Team". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22Return -1 in io_file_is_empty() if file cannot be accessed.Lukas Fleischer
Ensure files don't appear as empty if fopen() fails (e.g. on temporary EACCES failures). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for todo items.Lukas Fleischer
Use the new generic list implementation instead of "next" pointers in todo items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
