Using 'flag' results in duplicate code paths for short and long options.
This broke the -q short option in swaymsg, because there was:
{"quiet", no_argument, &quiet, 'q'}
Which will set quiet to 'q' and return 0, not 'q'.
First of all because it's not needed that early, and second of all
because there's a bug where calling `sway --get-socketpath` via `popen`
causes the child sway process to spin/hang instead of returning EOF.
(Specifically `(unset SWAYSOCK; swaymsg)` hangs.) This patch fixes that.
(Also note that this patch moves the "detailed review" comment, so I
guess this patch requires extra detailed review?)
This function looks for bound commands that start with `workspace` (ie.
the commands that change to a static workspace) and fetches the
workspace name.
However, if it's actually a list of commands, then the parsing will pick
up the delimiter ("," or ";") and also fail to recognize keywords
("next" etc).
This patch fixes that by properly separating with delimiters.
This makes escaping the arguments obsolete.
Also avoid dynamic memory allocation for the output id. It only supported ids up
to 99. Now we support up to 999, and take 4 bytes off the stack instead.
A criteria is a string in the form of `[class="regex.*" title="str"]`.
It is stored in a struct with a list of *tokens* which is a
attribute/value pair (stored as a `crit_token` struct). Most tokens will
also have a precompiled regex stored that will be used during criteria
matching.
for_window command: When a new view is created its metadata is tested
against all stored criteria, and if a match is found the associated
command list is executed.
Unfortunately some metadata is not available in sway at the moment
(specifically `instance`, `window_role` and `urgent`). Any criteria
string that tries to match an unsupported attribute will fail.
(Note that while the criteria code can be used to parse any criteria
string it is currently only used by the `for_window` command.)
This fixes a compiler warning:
../sway/extensions.c: In function ‘set_background’:
../sway/extensions.c:16:37: warning: implicit declaration of function ‘malloc’ [-Wimplicit-function-declaration]
struct background_config *config = malloc(sizeof(struct background_config));
^
../sway/extensions.c:16:37: warning: incompatible implicit declaration of built-in function ‘malloc’
../sway/extensions.c:16:37: note: include ‘<stdlib.h>’ or provide a declaration of ‘malloc’
We can't handle them currently (the criteria needs to e.g. be passed to
each command handler which then needs to do the right thing), so it's
better to just do nothing than to create unexpected results (because the
command was executed on the wrong view).
(Before this patch any command list with a criteria string would simply
fail to parse, so this is at least a step in the right direction.)
This also fixes a bug where issuing a new "workspace a output b" command
for an already assigned workspace would not work (the old config would
be found first and used instead).
