2023-05-16improve to use proper includesHiltjo Posthuma
Reduce using some of the unneeded sys/* headers too. This makes it slightly more portable or easier to port also.
2023-05-07iterate on previous commit which adds $SFEED_NEW_MAX_SECSHiltjo Posthuma
Separate the common pattern to get the time to compare new items in format tools to the new util function: getcomparetime(). Some changes and notes: - Change it so it is OK to set this value to 0 or negative (in the future). - sfeed_curses: truncating newmaxsecs to an int would limit the value too much. - Just use strtotime() and parse the value to time_t. This is a signed long (32-bit, until 2038) or signed long long (64-bit) on most platforms. - sfeed_curses gets the comparison time on reload aswell and it needs errno = 0, because it uses die(). time() is not guaranteed to set an errno if it fails. - Rename environment variable to $SFEED_NEW_AGE.
2023-05-07sfeed_{curses,frames,gopher,html,plain}: SFEED_NEW_MAX_SECSAlvar Penning
By introducing the new environment variable $SFEED_NEW_MAX_SECS in all sfeed_* utilities marking feeds as new based on comparing their age, it is now possible to override this age limit. This allows, for example, to be notified about new feeds within the last hour with SFEED_NEW_MAX_SECS=3600 sfeed_plain ~/.sfeed/feeds/* while creating a beautiful web report for last week's news by SFEED_NEW_MAX_SECS=604800 sfeed_html ~/.sfeed/feeds/*
2022-03-27Revert "rm sys/types.h include and improve portability"Hiltjo Posthuma
This reverts commit db1dcafd03997127f2cbc82376e2cc8df9b77356. This is needed. Tested on an (old) Slackware 11 install.
2022-03-25rm sys/types.h include and improve portabilityHiltjo Posthuma
This include is not needed. It was intended for ssize_t but this is already defined by stdio.h for getline().
2022-03-20check write errors on the output stream after each feedHiltjo Posthuma
This will detect write errors sooner.
2022-03-15stricter error checking in file streams (input, output)Hiltjo Posthuma
This also makes the programs exit with a non-zero status when a read or write error occurs. This makes checking the exit status more reliable in scripts. A simple example to simulate a disk with no space left: curl -s 'https://codemadness.org/atom.xml' | sfeed > f /mnt/test: write failed, file system is full echo $? 0 Which now produces: curl -s 'https://codemadness.org/atom.xml' | sfeed > f /mnt/test: write failed, file system is full write error: <stdout> echo $? 1 Tested with a small mfs on OpenBSD, fstab entry: swap /mnt/test mfs rw,nodev,nosuid,-s=1M 0 0
2022-03-14improve time(NULL) error checkingHiltjo Posthuma
Use errx, time(NULL) does not set errno. For sfeed_curses reset errno so it doesn't print a random error if it failed. POSIX recommends checking against (time_t)-1 on failure. Note that some implementation, like the OpenBSD man page says time() cannot fail.
2021-08-03code-style: use a newline before return in main()Hiltjo Posthuma
2021-06-01portability and standards: add BSD-like err() and errx() functionsHiltjo Posthuma
These are BSD functions. - HaikuOS now compiles without having to use libbsd. - Tested on SerenityOS (for fun), which doesn't have these functions (yet). With a small change to support wcwidth() sfeed works on SerenityOS.
2021-01-10optimize converting UNIX timestamp to localtimeHiltjo Posthuma
Make a huge difference (cuts the time in half to process the same amount of lines) on atleast glibc 2.30 on Void Linux. Seems to make no difference on OpenBSD. - This removes atleast one heap allocation per line (checked with valgrind). This is because glibc will strdup() the environment variable $TZ and free it each time, which is pointless here and wasteful. - localtime_r does not require to set the variables like tzname. In glibc-2.30/time/tzset.c in __tz_convert is the following code and comment: /* Update internal database according to current TZ setting. POSIX.1 8.3.7.2 says that localtime_r is not required to set tzname. This is a good idea since this allows at least a bit more parallelism. */ tzset_internal (tp == &_tmbuf && use_localtime); This makes it always tzset() and inspect the environment $TZ etc. While with localtime_r it will only initialize it once: static void tzset_internal (int always) { [...] if (is_initialized && !always) return;
2020-07-05format tools: don't skip items with a missing/invalid timestamp fieldHiltjo Posthuma
Handle it appropriately in the context of each format tool. Output the item but keep it blanked. NOTE: maybe in sfeed_twtxt it should use the current time instead?
2020-04-01util: improve/cleanup parseline()Hiltjo Posthuma
- remove a check that has no use/can never happen. - remove the return value as it's unused and the input size is known. - fix an old comment that doesn't reflect what the function does anymore.
2020-01-24cleanup some includesHiltjo Posthuma

2018-03-11sfeed_plain: don't flush line (was used for tail -f)Hiltjo Posthuma
2018-03-11include <sys/types.h> for types size_t, ssize_t etcHiltjo Posthuma
This makes sure xml.c in particular can be compiled without further feature macros.

this makes sure tail -f with multiple files ignores the ==> file <== lines too.
2017-06-29sfeed_plain: use setlocale() for glibcHiltjo Posthuma
this is required for mbtowc for glibc (not required in musl or on OpenBSD).

2016-04-10remove basename, just use last part of the path...Hiltjo Posthuma
... as a bonus it also saves an allocation.
2016-03-29add time parsing to sfeed itself, remove time fieldHiltjo Posthuma
- less overhead (we only need GMT time) so no setenv("TZ", ...) tzset() crap. - timezone format (for example %z in strptime) is non-standard, this will add some lines of code and some complexity to our code though, but the trade-off is worth it imho.
2016-02-28null-terminate line at newline from getline()Hiltjo Posthuma
2016-02-27various improvementsHiltjo Posthuma
- pledge tools and add define to enable it on platforms that support it, currently only OpenBSD 5.9+ - separate getline and parseline functionality. - use murmur3 hash instead of jenkins1: faster and less collisions. - make some error messages a bit more clear, for example with path truncation. - some small cleanups, move printutf8pad to util.

2015-08-07util: strtotime: stricter time parsingHiltjo Posthuma
as input: an empty string or non-digit characters are digits are considered an error now. Still, for the format tools output the formatted time string as time_t 0 on a parse error.

2015-07-31Various improvementsHiltjo Posthuma
- Only escape characters in "content" field, these can contain newlines. - Trim newlines and tabs, etc from the title, id and author fields. - Make decodefield, xmlencode functions easier to "chain" without allocatting new buffers. - Move printutf8pad from util (only used by sfeed_plain) to sfeed_plain. - Update README, still need to update the man-page and improve the documentation in general. - Code cleanup.
