* tmac/tmac.an: define .MR in a groff compatible wayDmitri Vereshchagin2025-07-27297-1623/+1623
| | | | | | | | | | | | | | | | groff 1.23.0 added .MR to its -man macro package. The NEWS file states that the inclusion of the macro "was prompted by its introduction to Plan 9 from User Space's troff in August 2020." From d32deab it seems that the name for Plan 9 from User Space's implementation was suggested by groff maintainer G. Brandon Robinson. Not sure if the intention was to make these definitions compatible, but it would be nice if they were. Currently, Plan 9 from User Space's .MR expects its second argument to be parenthesized. groff's .MR does not. This results in extra parentheses appearing in manual references when viewing Plan 9 from User Space's manual pages on a system using groff.
* ci: add Dependabot for GitHub ActionsKare Nuorteva2025-07-271-0/+10
| | | | | | | | Dependabot automatically maintains GitHub Actions workflows by sending Pull Requests to project when action updates are released. Dependabot labels the pull requests 'ci: bump actions/checkout from v3 to v4'. Dependabot opens a maximum of five Pull Requests at a time and reviews the need for PRs once a week.
* src/cmd/rc: import rc syntax `delim{cmd} for splitting commands from 9atomlufia2025-07-277-10/+38

* SunOS: silence some warningsDan Cross2025-07-252-2/+2
| | | | | | Give `-Wformat=0` on illumos/Solaris so that the build does not complain about `execlp` not having a sentinel (it's nil). Also fix an integer size issue when casting to a void pointer.
* DragonFly: fix buildDan Cross2025-07-253-4/+13
| | | | Fix the build for DragonFlyBSD.
* libthread: remove check for LinuxThreadsDan Cross2025-07-251-15/+0
| | | | | | | | | | | libthread had code in `_pthreadinit` to test for LinuxThreads, and error if it was in use. This hasn't been relevant since Linux 2.6, and I can't imagine there are many people trying to build (recent) plan9port on systems that old. Unfortunately, this code violated aliasing rules, and compilers were complaining about it. But, since it likely hasn't had much relevance in 20ish years, we can probably just remove it.
* all: remove need for `-fcommon`Dan Cross2025-07-2539-193/+339
| | | | | | | | | | Use `extern` where appropriate so that we can remove `-fcommon` on macOS and others. On macOS, `-fcommon` generates a number of linker warnings. I've tested building on macOS, Linux, FreeBSD, NetBSD, OpenBSD and illumos. I am not in a position to test on AIX or other more esoteric platforms, however.
* rio: proper prototypes in `fns.h`Dan Cross2025-07-2510-93/+98
| | | | | Use proper function prototypes in `fns.h`, that include argument type information.
* all: clean up misleading indentation warningsDan Cross2025-07-256-22/+28
| | | | | | | | | Misleading indentation warnings are actually useful, as they will occasionally reveal actual bugs (cf the apple `goto fail` security bug from a few years ago). Newer versions of clang (at least) are more aggressive about warnings in this regard, which has exposed a few warnings that are annoying. However, they are easy to address.
* sort: rename kcmp to keycmpDan Cross2025-07-241-6/+6
| | | | | Fixes: #648 Fixes: #655
* INSTALL: set defaults for awk and egrepDan Cross2025-07-241-6/+2
| | | | | | | Set defaults for `awk` and `egrep`, instead of setting things multiple times when specializing on OS, and using a default in a `case` statement. This is cleaner and less error-prone.
* warnings: fix warnings on newer compilersDan Cross2025-07-245-15/+21
| | | | | | | | | | Mostly turning the crank on fixing simple warnings: arrays, for instance, can never be nil. A couple of pointers should have been initialized to `nil` before being tested. Some logic in `troff` was simplified: basically, an `if` statement had a condition that must have always been true if that section of code were being executed at all.
* config: add $egrepDan Cross2025-07-239-11/+27
| | | | | | | | | | | Introduce a new variable set in $PLAN9/config: $egrep, which is conditionally set to either `egrep` or `grep -E`, based on platform, and use this when we want to invoke `egrep`. This works around the endless warnings from GNU grep stating that `egrep` is deprecated in favor of `grep -E`, when run on e.g. Linux.
* 9c: change -std=c17 to -stc=c11 based on feedback in \#716erentar2025-07-221-1/+1

* u.h: define __USE_POSIX to make glibc happyerentar2025-07-221-1/+1

* cmd/devdraw: avoid use of X button state fieldRoger Peppe2025-03-291-51/+12
| | | | | | | | | | | | | | | | | | This bug is an intermittent annoyance and does not seem likely to be fixed soon. It means that every so often my acme becomes unusable because it behaves as if a mouse button is permanently set. Avoid that issue by keeping track of mouse button state directly. While we're about it, fix another annoying issue: under Linux the FocusOut event reset the kstate field but not the kbuttons field, meaning that the buttons state could inappropriately persist. This happened occasionally by accident, but was easy to reproduce: with the mouse button held down, drag outside the window and click Alt-Tab to switch away from the window. We see a KeyDown event followed by FocusOut but no KeyUp event. Change-Id: I3708316478c80c41806d7157ae9929c6cd84b662

* dist/main.html: remove dead link to Belorussian translationmacie2025-02-171-2/+0
| | | | | | According to web.archive.org this link is dead since 2012/2013. According to original issue (http://codereview.appspot.com/4251044) that translation could be a machine translation.
* man: don't paginate when using nroffAnthony Sorace2025-01-292-6/+9
| | | | | | This tells bin/man to set the register L to very high to avoid pagination and updates tmac/tmac.an to use that value, if it's set, to set the page length. This is per Plan 9's rc/bin/man and sys/lib/tmac/tmac.an.

| | | | | | | | | Basic configuration which builds p9p on latest Ubuntu & macOS. Skipped on adding more operating systems as build would hold up waiting for runners, whereas with -latest targets, build starts immediately. Supported runners can be found on https://docs.github.com/en/actions/using-jobs/choosing-the-runner-for-a-job

* acme: have Dump save both low and high DPI fontnamesmatheuristic2023-09-051-4/+13
| | | | | | | | Instead of only saving a window's currently displayed font's name to the dump file, have Acme's Dump command save that window's combined low DPI and high DPI font names when both are available. See 9fans/plan9port#630
* libframe: Match the color of tickjapanoise2023-08-231-1/+1
| | | | | | | Previously the vertical bar in tick was always black; fine if you use the standard black-on-white for everything, but any attempt to add a dark mode ran into trouble with the tick being half hard-coded black, half the new text color.
* libdraw: fix subfont scalingmatheuristic2023-08-211-1/+1
| | | | | A subfont with n chars has n+1 Fontchars, so scalesubfont() needs to scale all n+1 info entries.
* libregexp: allow up to 127 captured subexpressions in one regexpIgor Burago2023-03-311-1/+1
| | | | 128 counting with the entire expression match ($0).
* plumber: increase NMATCHSUBEXP up to 100Igor Burago2023-03-311-1/+1
| | | | | Thus up to two-digit subexpression match variables are supported ($1 through $99) in addition to the entire expression match ($0).
