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.
2021-12-23sfeed_atom: add category field(s)Hiltjo Posthuma
2021-07-19code-style: change gmtime to the reentrant/thread-safe gmtime_rHiltjo Posthuma
No functional or performance difference (intended) because these programs are not threaded.
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.
2021-01-08sfeed_atom: code-style: use conditional with pledge, like the other toolsHiltjo Posthuma
2020-07-05sfeed_atom: minor simplification, gmtime_r is not needed hereHiltjo Posthuma
2020-07-05sfeed_atom: the updated field is mandatory: use the current time...Hiltjo Posthuma
... if it is missing/invalid.
2020-07-05sfeed_atom: fix timezone, output if timestamp is setHiltjo Posthuma
Timezone should be GMT (as intended), do not convert to localtime.
2020-06-04sfeed_atom: make the output more conformHiltjo Posthuma
- Set mandatory entry tags: id, updated. - Change entry published (optional tag) to updated (mandatory). - Add <feed> tags: author name, id, updated, title. Thanks lich for the feedback and testing.
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.
