* | Mark several functions staticLukas Fleischer2012-04-205-5/+5
| | | | | | | | | | | | | | These are not needed outside of the corresponding compilation units. Spotted with "-Wmissing-prototypes". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | 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>
* | src/calcurse.c: Start all helper threads in one goLukas Fleischer2012-04-121-2/+4
| | | | | | | | | | | | | | | | Makes our initialization code a tad cleaner and seems to reduce flicker when starting calcurse (the notification bar is no longer drawn before other windows are shown). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Refactor startup screen branchLukas Fleischer2012-04-123-17/+14
| | | | | | | | | | | | | | Removes the pointless first parameter to io_startup_screen() and saves one wins_update() call if system dialogs are disabled. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Use percentage-based width for the sidebarLukas Fleischer2012-04-121-23/+14
| | | | | | | | | | | | | | | | | | | | Use percentage-based widths internally. This slightly impairs (user) feedback but brings the sidebar configuration menu closer to the actual configuration format (the user now configures percentage-based widths, not absolute width values). As a bonus, the sidebar is now resized automatically on each window resize (based on the percentage values). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/mem.c: Fix putchar() parameterLukas Fleischer2012-04-061-1/+1
| | | | | | | | | | | | putchar() expects a single character, not a string. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Miscellaneous small code cleanupsLukas Fleischer2012-04-068-29/+24
| | | | | | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/keys.c: Use generic list implementationLukas Fleischer2012-04-051-77/+36
| | | | | | | | | | | | | | | | Be consistent and replace the custom linked list implementation we used here by the generic list implementation we use everywhere else. This reduces code complexity, while slightly improving memory overhead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Mark some more variables/parameters constantLukas Fleischer2012-04-054-7/+7
| | | | | | | | | | | | Fixes a couple of warnings seen with GCC 4.7. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Mark localized string literals constantLukas Fleischer2012-04-0512-89/+89
| | | | | | | | | | | | | | Translated strings returned by gettext() are statically allocated and shouldn't be modified. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Do not use LLIST_*_CONT for appointmentsLukas Fleischer2012-03-301-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This no longer works since we allow appointments lasting longer than 24 hours. This means that there might be an appointment that starts after another one and lasts until the selected day, even though the former doesn't. A simple example, where the old LLIST_TS_FOREACH_CONT approach fails, is: 03/29/2012 @ 19:00 -> 03/30/2012 @ 10:00 |Long event 03/29/2012 @ 21:00 -> 03/29/2012 @ 23:15 |Event 1 (shown) 03/30/2012 @ 14:00 -> 03/30/2012 @ 15:00 |Event 2 (not shown) Instead, allow incoherent appointments and only break if the current appointment *starts after* the selected day.

* | Revert a bunch of strncmp() conversionsLukas Fleischer2012-03-302-23/+23
| | | | | | | | | | | | | | | | | | | | | | All strncmp() usages were replaced by (evidently) equivalent strcmp() invocations in commit 2c9499bf272e06a62902711c6c20621ef3f80e64. However, some of the strncmp() calls were perfectly justified and we actually broke iCal import and "C-"-style key bindings by converting them to strcmp(). Fix this by reverting all affected conversions. Reported-by: Baptiste Jonglez <baptiste@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Fix semantics of "general."{systemdialogs,progressbar}Lukas Fleischer2012-03-297-23/+23
| | | | | | | | | | | | | | | | | | 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>
* | src/config.c: Detect legacy configuration filesLukas Fleischer2012-03-291-0/+27
| | | | | | | | | | | | | | | | | | Check configuration variable names against a list of pre-3.0.0 configuration keys and display a warning if such a variable is found. This reduces the chance of users going wild due to the non-backwards compatible configuration file changes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Reorder configuration variablesLukas Fleischer2012-03-291-15/+15
| | | | | | | | | | | | | | Sort configuration variables lexicographically. This makes changes easier to locate. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Rename configuration variablesLukas Fleischer2012-03-271-22/+22
| | | | | | | | | | | | | | | | | | | | Classify configuration options into different sections. Use consistent names and formatting. This was discussed on the mailing lists. A script that updates configuration files will come in following patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Update copyright rangesLukas Fleischer2012-03-2632-34/+34
| | | | | | | | | | | | 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 Fleischer2012-03-126-26/+20
| | | | | | | | | | | | | | | | 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>
* | Get rid of string structuresLukas Fleischer2012-03-123-77/+71
| | | | | | | | | | | | | | | | These were only used to construct constant strings with additional length fields. However, we can just use standard constant character arrays instead and let the compiler calculate the string length. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Use strcmp() instead of strncmp()Lukas Fleischer2012-03-125-36/+36
| | | | | | | | | | | | | | | | | | 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 window resets in config menuLukas Fleischer2012-03-121-1/+4
| | | | | | | | | | | | | | There's no need to reset windows unless the layout was changed. Move wins_reset() to a separate branch to reflect this. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Avoid redundant virtual screen updatesLukas Fleischer2012-03-122-3/+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>
* | Break out configuration main menuLukas Fleischer2012-03-023-49/+58
| | | | | | | | | | | | | | This was the only big block of code left in our main loop. Move it to a separate function, making the main loop a bit clearer. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Revamp key bindings displayLukas Fleischer2012-03-024-69/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the logic inside keys_display_bindings_bar() and remove the need to place the "show next page" key binding at the right positions. This used to be a pain to maintain, since we always had to move key bindings around when introducing a new key. Fix this by passing the actual key bindings in an array and using a separate parameter for the "show next page" key binding (which is automatically inserted at the right places from now on). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Add a read-only optionLukas Fleischer2012-02-245-18/+38
| | | | | | | | | | | | | | 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>
* | {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>
* | Fix up fscanf() format stringsLukas Fleischer2012-02-192-4/+4
| | | | | | | | | | | | | | 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 Fleischer2012-02-193-13/+18
| | | | | | | | | | | | | | | | | | | | 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>
* | Fix POSIX complianceLukas Fleischer2012-02-192-0/+6
| | | | | | | | | | | | | | | | | | | | | | * "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>
* | Remove all usages of bzero() and bcopy()Lukas Fleischer2012-02-195-13/+13
| | | | | | | | | | | | | | | | | | 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>
* | Fix up strncat() usageLukas Fleischer2012-02-184-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last argument to strncat() should not be the total buffer length; it should be the space remaining: The strncat() function shall append not more than n bytes (a null byte and bytes that follow it are not appended) from the array pointed to by s2 to the end of the string pointed to by s1. The initial byte of s2 overwrites the null byte at the end of s1. A terminating null byte is always appended to the result. This patch fixes a couple of potential buffer overflow vulnerabilities.

* | 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>
* | Don't chomp on error in ical_readline_init()Lukas Fleischer2012-02-181-4/+6
| | | | | | | | | | | | | | Skip the newline check if fgets() returns a NULL string. Fixes another 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>
* | Trap fgets() failure in *_scan()Lukas Fleischer2012-02-183-4/+12
| | | | | | | | | | | | | | | | Ensure we don't read arbitrary data when fgets() returns a NULL string (meaning that either the EOF is encountered or an error occurred). This also fixes a couple of compiler warnings seen with "-Wunused-result". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Add missing configuration variablesLukas Fleischer2012-02-171-15/+42
| | | | | | | | | | | | | | Append missing configuration variables to the end of our configuration file instead of keeping them undefined. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Revamp configuration file parsingLukas Fleischer2012-02-171-130/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reintroduce a map for configuration variable parsing. We use a different approach this time: Each map entry contains * a key, * a callback that can be used to parse that variable, * a callback that can be used to serialize that variable and * a target buffer that the parsed value is written to/read from. Commits 4f4891bdb88410ae04225f3d6acfa31d73a3901a and 6377582841118688aee13aff98c9216403582e45 show that we are pretty undecided on using a map or not. However, now that we use parser and serialization wrappers for every variable, having a central map makes everything much cleaner. The runtimes of config_load() and config_save() are slightly increased (by a constant factor). This will also allow us for implementing proper detection of missing configuration variables in the configuration file. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Add more parser/serialization wrappersLukas Fleischer2012-02-171-67/+133
| | | | | | | | | | | | | | | | | | | | | | | | Add convenience parser/serialization wrappers for all configuration variables that don't use the default config_parse_*() and config_serialize_*() helpers yet. This is nothing but a dirty hack and should be refactored later (e.g. by separating configuration variable parsing and validation or by adding optional validation functions). It makes it easier to switch to a more generic configuration parser, though. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | src/config.c: Introduce config_parse_str()Lukas Fleischer2012-02-171-13/+14
| | | | | | | | | | | | Be consistent with other parser helpers and with config_serialize_str(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | 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).
