* Miscellaneous small code cleanupsLukas Fleischer2012-04-061-3/+2
| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Mark some more variables/parameters constantLukas Fleischer2012-04-051-2/+2
| | | | | | Fixes a couple of warnings seen with GCC 4.7. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Mark localized string literals constantLukas Fleischer2012-04-051-22/+22
| | | | | | | Translated strings returned by gettext() are statically allocated and shouldn't be modified. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix semantics of "general."{systemdialogs,progressbar}Lukas Fleischer2012-03-291-6/+6
| | | | | | | | | 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>
* Update copyright rangesLukas Fleischer2012-03-261-1/+1
| | | | | | Add 2012 to the copyright range for all source and documentation files. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add a read-only optionLukas Fleischer2012-02-241-8/+24
| | | | | | | 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>
* src/io.c: Remove C89 incompatible commentLukas Fleischer2012-02-201-1/+1
| | | | | | | Make commenting style consistent with everywhere else. Use "/* [...] */" instead of "// [...]". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix up fscanf() format stringsLukas Fleischer2012-02-191-3/+3
| | | | | | | All members of the tm structure are signed integers. Stick to using the correct fscanf() format specifiers for these. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix hash table issues with ISO C99Lukas Fleischer2012-02-191-7/+10
| | | | | | | | | | ISO C99 forbids unnamed structs/unions and nested functions. Move the "HTABLE_HEAD" and "HTABLE_GENERATE" parts out of the function body and place them at the very top of the file (where function definitions are allowed). Also, remove the unnamed struct from "htable.h" (which was useless anyway). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Remove all usages of bzero() and bcopy()Lukas Fleischer2012-02-191-2/+2
| | | | | | | | | The bzero() and bcopy() functions are deprecated and were removed from the POSIX standard in IEEE Std. 1003.1-2008. Remove all usages of bzero()/bcopy() and replace them by appropriate memset()/memmove() calls. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/io.c: Use fork_exec() instead of system()Lukas Fleischer2012-02-181-3/+4
| | | | | | | Speeds up execution, prevents failures when pager or log file contains spaces, fixes a warning seen with "-Wunused-result". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add stricter syntax checking to io_load_*()Lukas Fleischer2012-02-181-33/+41
| | | | | | | | | | Be more restrictive with what we allow in data files and bail out if a line doesn't conform to our specification, especially in regard to separators. This prevents unexpected behavior when a data file is edited manually. As a bonus, this fixes a whole pile of compiler warnings previously seen with "-Wunused-result". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Break out different import/export formatsLukas Fleischer2012-01-071-1501/+8
| | | | | | | | | | | | | | | | | | | | | | 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>

| * 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.

* | Extract config file handlers into a separate fileLukas Fleischer2011-12-091-142/+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>

| * src/io.c: Avoid use of memcpy()Lukas Fleischer2011-11-111-2/+4
| | | | | | | | | | | | | | | | Use strncpy() and a proper limit, which ensures we never read more characters than the buffer can hold. Also, ensure we always null-terminate strings here. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
| * src/io.c: Null-terminate the ical_readline() bufferLukas Fleischer2011-11-111-0/+1

* | Use a global configuration variableLukas Fleischer2011-11-141-28/+26
| | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | Always invoke pthread_join() when we blow up a thread via pthread_cancel() (avoid zombie threads). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
| * src/io.c: Update todo item count on iCal importLukas Fleischer2011-10-041-0/+3
| | | | | | | | | | | | | | Update the number of todo items when importing an iCal file to prevent some items from being inaccessible. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Remove parentheses from return statementsLukas Fleischer2011-11-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | Do not cast unused return values to voidLukas Fleischer2011-11-021-268/+262
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | Avoid use of printf()/fprintf()Lukas Fleischer2011-11-021-115/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Pass item durations to recur_item_inday()Lukas Fleischer2011-10-211-2/+2
| | | | | | | | | | | | | | | | Having item's durations eventually allows for better parsing of recurrent appointments as we might be interested in how many days are covered by a multi-day appointment. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Add configuration option to run the GC on exitLukas Fleischer2011-10-051-0/+5
| | | | | | | | | | | | | | | | If "auto_gc" is enabled, the garbage collector for note files will be run on every exit. As this is an experimental feature and may cause data loss, this is disabled by default. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Do not unlink() note files on note removalLukas Fleischer2011-10-051-3/+3
| | | | | | | | | | | | | | | | | | | | 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>

| * src/io.c: iCal content line folding correctnessLukas Fleischer2011-08-261-112/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a rather invasive change that introduces correct line folding to our iCal parser. From now on, ical_readline() should be used instead of fgets() to read lines from an iCal file as it unfolds lines automatically. We also need to use shared buffers as each ical_readline() invocation eats up the first part of the next line and stores it in the "lstore" buffer. Subsequent ical_readline() invocations copy the contents of this buffer and append continuation lines. We currently use a single buffer pair that is allocated in io_import_data() and pass it to all subroutines. ical_readline_init() needs to be called once for every buffer pair. It reads the first part of the current line and writes to "lstore", clearing the target buffer at the same time. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Add configuration option to notify all appointmentsLukas Fleischer2011-07-311-0/+4
| | | | | | | | | | | | | | | | If "notify-all" is enabled, all non-flagged appointments will be notified (instead of flagged ones). This is useful for users that want to be notified of everything. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | Split stats messages in io_import_data()Lukas Fleischer2011-07-241-10/+12
| | | | | | | | | | | | | | | | Use separate format strings for separate values. This is useful in case we want to output similar stats somewhere else and is a preparation for supporting plural forms. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
