* | src/config.c: Keep formatting and commentsLukas Fleischer2012-02-171-131/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | Switch to using the new config_file_walk() helper in config_save() and update existing configuration variables instead of blindly overwriting the existing configuration file. Note: This breaks configuration setting storage if one or more settings are missing in the configuration file. We need to refactor our parser and serialization routines another time before this can be implemented properly, though. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Add serialization helperLukas Fleischer2012-02-171-53/+184
| | | | | | | | | | | | | | Add config_serialize_conf() which can be used to serialize the value of a configuration setting (counterpart to config_parse_conf()). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Add junk callback to config_file_walk()Lukas Fleischer2012-02-161-3/+9
| | | | | | | | | | | | | | | | | | | | This can be used if we care about junk, such as empty lines and comments. Currently unused since we skip these when parsing configuration settings. This makes sense if we want to make slight modifications to the configuration file without losing formatting and comments, though. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Make config file reading more flexibleLukas Fleischer2012-02-161-11/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds one level of abstraction to config_load() by splitting out the actual reading routine and the variable setter into two separate functions. config_file_walk() can be used to read the configuration file, strip comments and pass every key/value pair to a callback. config_load_cb() is the new callback used in config_load(). Rationale: It makes sense to reuse the key/value parser to allow for a much saner config_save() routine that changes single values only instead of rewriting (and overwriting) the whole configuration file every time.

* | src/llist.c: Bail out early on negative indexesLukas Fleischer2012-02-161-1/+7
| | | | | | | | | | | | | | Make sure we don't return bogus list elements if negative indexes are used in llist_{,find_}nth(). Bail out early and return NULL instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/calendar.c: Fix range check in calendar_move()Lukas Fleischer2012-01-211-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We added count prefix support to motion commands in commit 59e006e56d9f893506af56a4ca114fe53b537e49 but obviously forgot to check whether the range checks in calendar_move() still work correctly. Refactor out range checks and replace them by a single check that is performed *after* the new date is computed, but before we assign the new value to the actual selected date. This ensures we won't have to bother about these again when changing/adding functionality in/to calendar_move(), while keeping performance (date_change() is pretty cheap and range violations are corner cases anyway).

* | Split note file generation into separate functionLukas Fleischer2012-01-173-12/+23
| | | | | | | | | | | | | | We currently use this in one place only but might reuse this a couple of times later (when migrating to libical). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Break out different import/export formatsLukas Fleischer2012-01-075-1501/+1598
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* | src/apoint.c: Fix a length bug introduced by new duration formatBaptiste Jonglez2012-01-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 4ff3bb9d introduced a new format for parsing durations, thus allowing a larger string to be retrieved from user input. However, the string used is still declared with the old length, leading to crashes when compiling with stack-smashing protection features (the default on Archlinux). Inputting a duration string of more than 8 characters (such as "+1d11h11m") would crash calcurse with a *** stack smashing detected *** message. Using a larger string from the start fixes the bug.

| * Format "DURATION" field properly on ical exportJérôme Pinot2011-12-161-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | Use days/hours/minutes/seconds instead of seconds in the DURATION field. It fixes interaction with other softwares like phpicalendar. Lukas: Remove use of dur-week. RFC 5545 states that you cannot use this in conjunction with dur-day. Also, fix formatting and use proper constants.

* | src/config.c: Drop support for legacy color schemesLukas Fleischer2011-12-121-85/+36
| | | | | | | | | | | | | | | | | | We used different naming schemes in versions prior to 1.8. Given that calcurse 1.8 has been released more than 4.5 years ago, remove the legacy code that still handles these. Users upgrading from <1.8 to 3.0.0 might need to convert the appropriate config file variable manually. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | src/config.c: Remove map for configuration variablesLukas Fleischer2011-12-091-169/+114
| | | | | | | | | | | | | | | | | | | | This patch kind of reverts what we did in commit 6377582841118688aee13aff98c9216403582e45. We were a tad off-base there since using a map doesn't improve maintainability, really. Using strcmp() at a central location seems perfectly fine and doesn't have the overhead of the map scanning algorithm. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Extract config file handlers into a separate fileLukas Fleischer2011-12-098-550/+594

| | | | | | | | | | | | | | | | | | | | | | | | * Move print_notefile() from "src/args.c" to "src/utils.c". * Add a "%N" format specifier to print_*().

| | | | | | | | | | | | | | | | | | Add print_recur_apoint() and print_recur_event() helper functions to print recurrent items to stdout and use them everywhere.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Avoid unnecessary start time calculationsLukas Fleischer2011-10-215-23/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename recur_*_inday() to recur_*_find_occurrence() and use the new functions whenever we actually care about the start time of an occurrence. Reintroduce recur_*_inday() as wrappers to recur_*_find_occurrence() and pass NULL as start time buffer (which means "skip start time calculation"). Keep using these when we only want to know if a recurrent item belongs to a specific day but do not care about the actual start time. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/day.c: Allow editing an item's durationLukas Fleischer2011-10-211-5/+47

This version can deal with recurrent multi-day appointments unless they overlap. In case of overlapping appointments, only the last appointment that starts before the current day is shown. We will need to rewrite the whole recur_item_inday() interface in order to fix this - this relatively trivial patch is only the first step. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | Pass item durations to recur_item_inday()Lukas Fleischer2011-10-214-12/+13
