* Allow passing additional parameters to shell_exec()Lukas Fleischer2012-05-161-3/+40
| | | | | | | | 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>
* Allow resize events while prompting the userBaptiste Jonglez2012-05-141-1/+6
| | | | | | | | | | When asking the user to choose between multiple alternatives, properly handle resize events. Note that we would also need to do so in getstring()... Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Various fixes.Baptiste Jonglez2012-05-141-2/+2
| | | | | | | Use snprintf(3) instead of sprintf(3) and fix a missing i18n tag. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Factorize boolean user prompting.Baptiste Jonglez2012-05-141-7/+11
| | | | | | | | | | | 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.

* src/utils.c: Add a status_ask_simplechoice() functionBaptiste Jonglez2012-05-141-0/+33
| | | | | | | | | | We need a simpler version, based on the previously defined `status_ask_choice()` function, that asks to choose amongst a number of alternatives that can simply enumerated, without needing to bind keys on them.

* src/utils.c: Add a status_ask_choice() functionBaptiste Jonglez2012-05-141-0/+42
| | | | | | | | | | | | | | | | | This function allows the user to choose between various alternatives, each one being associated to a given key. This will allow a great deal of factorisation, which will make it easier to handle special events (like resizing, user escape...) in an uniform manner. The cool part of the approach taken here is that it allows full i18n (i.e. the key bound to an alternative can be different depending on the language), at the expense of a somewhat less readable code on the caller side.

* Declare several parameters/variables constantLukas Fleischer2012-05-081-11/+11
| | | | | | | | | | | | 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>
* src/utils.c: Get rid of "semantic range checks" when parsing durationBaptiste Jonglez2012-05-021-13/+0
| | | | | | | | | | Don't restrict ranges when entering durations. We now accept duration like "+1d42h600m". This might not seem very logical, but it's perfectly valid, and being able to enter "+36h" is useful when you don't want to do the maths yourself.

* Merge "%(start"{,str}")" and "%(end"{,str}")"Lukas Fleischer2012-04-171-21/+13
| | | | | | | | | | | | | Add "default" and "epoch" extended formats for dates. "default" is the same as "%H:%M", "epoch" prints the number of seconds since January 1, 1970. Also, change the semantics of "%(start)" to return dates in default format (same format that "%(startstr)" used to use before this patch). The old "%(start)" behavior can be emulated by using "%(start:epoch)". The same applies to "%(end)" and "%(endstr)". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Support extended date formatsLukas Fleischer2012-04-171-2/+19
| | | | | | | Add support for appending a strftime()-style format string to "%(start)" and "%(end)". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Allow passing extended formatsLukas Fleischer2012-04-171-5/+24
| | | | | | | | | Extended formats can be specified by adding custom format strings to the end of a long format specifier, separated by a colon (":"). This feature is currently unused. Extended format support for several format specifiers will be added in following patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add support for long format specifiersLukas Fleischer2012-04-171-5/+43
| | | | | | | | | | | | | | | | Adds following long format specifiers for each short format specifier: * s: (start) * S: (startstr) * d: (duration) * e: (end) * E: (endstr) * m: (message) * n: (noteid) * N: (note) * p: (priority) Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/utils.c: Break out format specifier parsingLukas Fleischer2012-04-171-24/+72
| | | | | | | Move the format specifier parser to a separate function. This is done in preparation for supporting long format specifiers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Miscellaneous small code cleanupsLukas Fleischer2012-04-061-3/+10

* Mark some more variables/parameters constantLukas Fleischer2012-04-051-1/+1
| | | | | | Fixes a couple of warnings seen with GCC 4.7. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Mark localized string literals constantLukas Fleischer2012-04-051-3/+3
| | | | | | | Translated strings returned by gettext() are statically allocated and shouldn't be modified. 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>
* Do not strncpy() strings returned by gettext()Lukas Fleischer2012-03-121-4/+5
| | | | | | | | Translated strings returned by gettext() are statically allocated. There's no need to copy them to a buffer, we can use the pointers returned by gettext() instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use strcmp() instead of strncmp()Lukas Fleischer2012-03-121-1/+1
| | | | | | | | | 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>
* Avoid redundant virtual screen updatesLukas Fleischer2012-03-121-2/+0
| | | | | | | | | | Remove some redundant wnoutrefresh() invocations. There's no need to copy a window to the virtual screen unless doupdate() is invoked immediately afterwards. This reduces flicker when browsing in the calendar panel. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix POSIX complianceLukas Fleischer2012-02-191-0/+2
| | | | | | | | | | | * "WAIT_MYPGRP" isn't POSIX'ish. Relying on this caused compilation issues in certain environments (e.g. under Cygwin). As a workaround, define "WAIT_MYPGRP" explicitly if it's undefined. * "P_tmpdir" is an XSI extension. Don't try use it if it isn't available. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* src/utils.c: Support escape sequences in format stringsLukas Fleischer2011-11-221-0/+55
| | | | | | | We support all simple escape sequences listed in the ANSI C standard, plus "\0" to allow for printing null characters. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/utils.c: Support printing '%' in format stringsLukas Fleischer2011-11-141-0/+9
| | | | | | This allows using "%%" to print the '%' character. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* print_*(): Add format specifier to print notesLukas Fleischer2011-11-141-0/+61
| | | | | | | | | | | | * Move print_notefile() from "src/args.c" to "src/utils.c". * Add a "%N" format specifier to print_*(). This invokes print_notefile() and prints the content of an item's note file. * src/args.c: Use the new format specifier instead of print_notefile() everywhere. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a dynamic method to print todo items to stdoutLukas Fleischer2011-11-141-0/+34
| | | | | | | | | | | | This goes in line with the other commits adding print_*() support. Following format specifiers are allowed: * p: Print the priority of the item * m: Print the description of the item * n: Print the name of the note file belonging to the item Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a dynamic method to print recurrent items to stdoutLukas Fleischer2011-11-141-0/+27
| | | | | | | | | Add print_recur_apoint() and print_recur_event() helper functions to print recurrent items to stdout and use them everywhere. Currently, these are only wrapper functions to print_apoint() and print_event() that create temporary, non-recurrent items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a dynamic method to print events to stdoutLukas Fleischer2011-11-141-0/+31
| | | | | | | | | | | | | Add a flexible helper function print_event() and use it whenever we print events to stdout. This reduces the number of copy-pasted code and eventually allows for specifying custom format strings. Following format specifiers are supported: * m: Print the description of the item * n: Print the name of the note file belonging to the item Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a dynamic method to print appointments to stdoutLukas Fleischer2011-11-141-0/+49
| | | | | | | | | | | | | | | | | | Add a flexible helper function print_apoint() and use it whenever we print appointments to stdout. This reduces the number of copy-pasted code and eventually allows for specifying custom format strings. Following format specifiers are supported: * s: Print the start time of the appointment as UNIX time stamp * S: Print the start time of the appointment using the "hh:mm" format * d: Print the duration of the appointment in seconds * e: Print the end time of the appointment as UNIX time stamp * E: Print the end time of the appointment using the "hh:mm" format * m: Print the description of the item * n: Print the name of the note file belonging to the item Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Remove parentheses from return statementsLukas Fleischer2011-11-021-9/+9
| | | | | | | | | | | | | | 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>
* Make use of the NULL macroLukas Fleischer2011-11-021-2/+2
| | | | | | | | | | | | | | | Use this constant everywhere when referring to a null pointer instead of casting 0 to various types of pointers. Created using following semantic patch: @@ type type; @@ - (type *)0 + NULL Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not cast unused return values to voidLukas Fleischer2011-11-021-9/+9
| | | | | | | | | | | | | | | | | | | | 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 Fleischer2011-11-021-1/+1
| | | | | | | | | | | | | | | | 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>
* src/utils.c: Support more powerful duration stringsLukas Fleischer2011-10-061-23/+100
| | | | | | | | | Add support for "1d23h42m"-like duration strings to parse_duration(). Also, switch to using a deterministic finite automaton to parse duration strings, as things tend to get unclear. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/utils.c: Remove check_time()Lukas Fleischer2011-10-061-31/+0
| | | | | | | Now that parse_time() and parse_duration() do all the validation work, this isn't used (nor needed) any longer. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/utils.c: Introduce parse_{time,duration}()Lukas Fleischer2011-10-061-0/+85
| | | | | | | | | These helpers can be used in a fashion similar to parse_date(). In addition to check_time(), parse_time() and parse_duration() support short forms such as "23:" (instead of "23:00") and ":45" (instead of "00:45"). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/utils.c: Mark input string of parse_date() constLukas Fleischer2011-10-061-4/+4
| | | | | | | We don't mess about with the date string here, so it should be declared const. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not unlink() note files on note removalLukas Fleischer2011-10-051-4/+4
| | | | | | | | | | 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>
* Refactor out note functionsLukas Fleischer2011-07-211-18/+0
| | | | | | | | | | * 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>
* Merge branch 'maint'Lukas Fleischer2011-07-101-0/+15

* Use mem_free() instead of xfree() in check_time().Lukas Fleischer2011-04-171-1/+1
| | | | | | | xfree() should never be used directly and only be called by one of the mem_*() wrappers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix null pointer dereference in parse_date().Lukas Fleischer2011-04-121-9/+12
| | | | | | | | Passing a date in format "mm-dd-yy" where short forms are not allowed would lead to a null pointer dereference here. This one fixes that. Spotted by clang-analyzer. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
