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.
2021-06-01portability 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.
2021-05-27sfeed_frames/sfeed_html: show the total counts and improve the title formatHiltjo Posthuma
This title format now matches the one with sfeed_curses. It shows the count to the most left and makes it more readable imho. It also works better when the titlebar is small.
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;
2020-10-09fix counting due to uninitialized variable when the time could not be parsedHiltjo Posthuma
Since commit 276d5789fd91d1cbe84b7baee736dea28b1e04c0 if the time is empty or could not be parsed then it is shown/aligned as a blank space instead of being skipped. An oversight in this change was that items should be counted and set in `isnew`. This commit fixes the uninitialized variable and possible miscounting.
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?
2020-06-21sfeed_html/sfeed_frames: simplify struct feed allocationHiltjo Posthuma
There's no need for a dynamic struct feed **. The required size is known (argc). Just allocate it in one go.
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.
2020-03-11sfeed_html/sfeed_frames: fix bold markup for lynxHiltjo Posthuma
The previous style was not bold: <b><a href="">some link</a></b> The following link is now bold: <a href=""><b>some link</b></a>
2020-03-10sfeed_html/sfeed_frames: use a <pre> section per feedHiltjo Posthuma
This improves output with Dillo, w3m and possibly other simple browsers. - Dillo has a bug where it resets its block-style after <h2> when it is inside <pre>. Then it ignores newlines (inside <pre>) and the links are inlined. - w3m does not have a (line)margin for h2.
2019-07-20sfeed_gph: prefix/mark "new" items with "N" too.Hiltjo Posthuma
minor consistency fix in sfeed_html.c comment
2019-04-30sfeed_frames, sfeed_html: use the same code for link handlingHiltjo Posthuma
2019-04-20sfeed_frames, sfeed_html: do not send referer headerHiltjo Posthuma
Do not send referer header if the browser supports this tag. This makes sure in some browsers where referer hiding is not setup this header is still hidden. The proper way is to setup your browser environment however to strip/change the referer header and trim your browser footprint.
2019-04-06sfeed_frames/sfeed_html: improve HTML output a bitHiltjo Posthuma
declare UTF-8 before <title>
2018-11-04whitespace and comment fixHiltjo 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.
2017-12-24format programs: ignore fields with an invalid timeHiltjo Posthuma
this makes sure tail -f with multiple files ignores the ==> file <== lines too.

2017-04-27simplify pledge stubHiltjo Posthuma
2016-08-06sfeed_frames, sfeed_html: don't use HTML tablesHiltjo Posthuma
reasons: - HTML table rendering is extremely slow (invalidate because of resizing cells etc). - whitespace wrapping does not work properly in ancient browsers, links(1).
2016-08-06add USE_PLEDGE, remove pledge dummy functionHiltjo Posthuma
2016-04-10minor style fixesHiltjo Posthuma
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.

2015-08-16code-style + no need to zero static variablesHiltjo Posthuma
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.
2015-08-02util: simplify parseline() and check t for strtotime().Hiltjo Posthuma
2015-08-02refactor print, decodefield into xmlencodeHiltjo Posthuma
... put specific formatting-logic per program (printcontent()).
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.
