2023-02-16sfeed_curses: add SUN keys supportHiltjo Posthuma
This fixes the keys on the sun-color console on OpenIndiana/Illumos/OpenSolaris (and other systems using these keys). See also the table: https://invisible-island.net/xterm/ctlseqs/ctlseqs.html Section "Non-Function Keys".
2023-02-16sfeed_curses: add SCO keys for next, prior (CSI I and CSI G)Hiltjo Posthuma
This fixes the page up and page down keys in the cons25 console on DragonFlyBSD. See also the table: https://invisible-island.net/xterm/ctlseqs/ctlseqs.html Section "Non-Function Keys".

This was a copy-pasta.
2023-02-04sfeed_gopher: remove PATH_MAX and restricting the path lengthHiltjo Posthuma
This make it also cleanly compile without any other changes on GNU/Hurd. Reference: https://www.gnu.org/software/hurd/hurd/porting/guidelines.html Section: "PATH_MAX, MAX_PATH, MAXPATHLEN, _POSIX_PATH_MAX" The fopen() functions will return NULL when the path is too long and set errno = ENAMETOOLONG. "The length of a pathname exceeds {PATH_MAX}, or pathname resolution of a symbolic link produced an intermediate result with a length that exceeds {PATH_MAX}."

2023-01-18sfeedrc.5: improve documentation a bitHiltjo Posthuma
- Fix a typo "Url" -> "URL". - Be a bit more clear some overridable functions read from stdin. - Some small rewording.
2023-01-07sfeed.1: reference sfeed_opml_importHiltjo Posthuma
It is used in the examples. (Do not directly reference iconv to keep some kind of clear reference list)
2023-01-07sfeed.5: remove a caveat in the file format man pageHiltjo Posthuma
It is a caveat while parsing the data in the sfeed(1) program. Keep it described in the sfeed(1) man page.

2022-08-17sfeed_curses: fix a memleak caused by a mistake in refactoring the codeHiltjo Posthuma

2022-07-17sfeed_curses: cleanup code for handling read items from an URL fileHiltjo Posthuma
This makes it easier to reuse the code from reading plain-text list of items from a file and uses a struct urls to keep its state in a cleaner way. + some small code-style improvements and reshuffling. Inspired by a question from NRK by mail about implementing a "read later" feature. (A quick local experiment shows it can be done in ~70 lines of added code).
2022-07-05remove __dead codeNRK
this check is already done in util.h and is no longer needed after the `sfeed_curses -> sfeed` merge.
2022-07-05sfeed_curses: write out plumbercmd argument in a verbose mannerHiltjo Posthuma
Write it in a more verbose, clear and C90-style manner. This workarounds a bug in scc too (reported upstream and will be fixed of course). All tools in sfeed can now be compiled with minicurses-mode with the scc compiler and musl libc without any modifications needed. scc: http://www.simple-cc.org/

2022-06-18README: add setsid exampleHiltjo Posthuma
2022-06-06themes: simplify empty macros, remove do { } while(0)Hiltjo Posthuma
Multiple function calls should still be nested in a do { } while(0), but this is hopefully obvious looking at the other lines. While testing, gcc with -O0 created the same binary. clang added a single jmp instruction.
2022-06-05sfeed_curses: processexit(): remove unneeded code for non-interactive processesHiltjo Posthuma
This was used in commit a58fa45f25da4f18d7b8c1a815884f67b965406f and previous, but the code for non-interactive process cleanup was later removed, so clearing the struct is not not needed anymore, because it is unused.
2022-05-31README: fix bug in an example for counting the new items of the last dayHiltjo Posthuma
This should not use the plain-text URL file ($SFEED_URL_FILE).
2022-05-31minicurses.h: remove unneeded includeHiltjo Posthuma
In the past there was an ioctl() call in setupterm(), so this include is not needed anymore.
2022-05-21bump version to 1.5Hiltjo Posthuma
2022-05-19README: make sure sfeed_update errors don't write to stderrHiltjo Posthuma
It would mess up the output since the progress bar writes to stderr aswell.

2022-05-14manual pages: reword a few things a bit more clearlyHiltjo Posthuma
2022-05-07sfeed_curses: improve commentHiltjo Posthuma
Do not restart the syscall waitpid, explicitly mention not setting SA_RESTART.
2022-05-07sfeed_curses: interrupt waitpid while interactive child program is runningHiltjo Posthuma
This now handles SIGTERM on sfeed_curses properly while an interactive child program is running. Test-case program: https://git.codemadness.org/sfeed_tests/commit/cd4268d4f71b5d7ab0df593d95e70188475d76bb.html
2022-05-05sfeed_curses: close stdin for spawning a plumb program in non-interactive modeHiltjo Posthuma
This is only for plumbing in non-interactive mode in forkexec(), but not piping content. Probably obvious what the descriptors are, but also add a few comments to dup2 of the file descriptors (stdin, stdout, stderr). To reproduce a behaviour: Plumb script: #!/bin/sh dmenu Then launch it: SFEED_PLUMB_INTERACTIVE=0 SFEED_PLUMB=thescript sfeed_curses ~/.sfeed/feeds/* The program now waits on input while in non-interactive mode and only seems to hang. After: The program starts but just has no input passed to it.
2022-05-04sfeed_curses.1: more details about signals and (non-)interactive programsHiltjo Posthuma
- SIGINT: reword, canceling the line editor is the exception. - Document the order of signal handling. - Document interactive and non-interactive behaviour in a separate section and in more detail. Remove repetition for each *_INTERACTIVE environment variable. - Document SIGINT and SIGTERM exit status. - Typo: "statusbar" -> "status bar". - Reword a few sentences. With additional changes and feedback from adc, thanks!

2022-04-10sfeed_curses.1: fix typo: automaticly -> automaticallyHiltjo Posthuma
Noticed by the Debian scanner for typos (typo-in-manual-page): https://mentors.debian.net/package/sfeed/
2022-04-02bump version to 1.4Hiltjo Posthuma
2022-04-02sfeed_curses: code-style: mouse mode: just use a constantHiltjo Posthuma
No functional change intended. Just slightly more clear.
2022-04-02sfeed_curses: line editor: handle SIGCHLD directlyHiltjo Posthuma
This makes sure when processes exit they are reaped immediately (instead of after closing the line editor).
2022-04-02sfeed_curses: line editor, temporarily disable the mouse when using the line ↵Hiltjo Posthuma
editor This allows pasting in the terminal and also doesnt spam mouse events, which are not useful here.
2022-04-01sfeed_curses: don't use bitmasks to keep the states for signalsHiltjo Posthuma
Reported by Leon Fisher, thanks! "Each signal should have its own sig_atomic_t variable if you want to keep state for all of them independently." A similar issue was referenced in a OpenBSD tech mailinglist thread: https://marc.info/?l=openbsd-tech&m=162940120614641&w=2

2022-04-01sfeed_curses: improve multiple signal handlingHiltjo Posthuma
Keep a bitmask of the received signals and handle them all. Also handle them in a particular order now.
2022-03-31sfeed_curses: improve waiting on processes and reaping themHiltjo Posthuma
- Wait on the exact process id and get its status. - Handle SIGCHLD explicitly and reap zombie children: ignoring them by using sigaction(SIGCHLD, &sa, NULL); would be racy in this case because sfeed_curses has interactive and non-interactive programs. Note while testing: if the markread program would be slow and in the meantime a plumb process would exit. This signal is now pending and is a zombie process until the SIGCHLD signal can be processed. This is fine. This also fixes a regression from commit 30a70fa2dab1925b0eaea04f67e3f86b360386dd because SIGCHLD was ignored in the parent for interactive processes aswell. This broke reading the exit status of the markread program, reproducable by plumbing an item and then trying to mark it as read (with SFEED_URL_FILE set).
