I've tried to make as few changes, as possible.
Usually the reason for using qsort_r is, that you can pass an extra userdata pointer to the
compare function. However, in sway list_sort wrapped qsort_r and always called a wrapper
function for comparing, the wrapper function then had the real compare function as argument.
The only thing, that the wrapper function does, is dereferencing the 'left' and 'right' function
arguments before passing them to the real compare function.
I have renamed list_sort to list_qsort to avoid confusion (so nobody tries to use list_qsort like
list_sort) and removed the wrapper functionality. Now the dereferencing must be done in the
compare function, that gets passed.
Some compare functions were used in both list_sort and list_seq_find. To make the difference
clear, I've added a '_qsort' suffix to the compare functions, that are intended to be used with
the new list_qsort. (In other words: list_qsort is not compatible anymore with list_seq_find).
- Changed and renamed function (it isn't used anywhere but in commands.c, and only for sorting):
compare_set -> compare_set_qsort
- New wrapper functions:
sway_binding_cmp_qsort (for sway_binding_cmp)
sway_mouse_binding_cmp_qsort (for sway_mouse_binding_cmp)
This works by tracking the pids of the child processes in the related
output container and terminating the processes and spawning new ones on
a config reload.
Should solve: #347
CMake takes a `FALLBACK_CONFIG_DIR` flag which is the directory where the
standard configuration file `config` is copied at installation.
If loading from typical configuration directories fails, sway loads
FALLBACK_CONFIG_DIR/config (/etc/sway/config by default).
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 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).
When yes, the old behaviour of adding half the inner gap around each
view is used.
When no, don't add any gap when an edge of the view aligns with the
workspace. The result is inner gap only between views, not against the
workspace edge.
The algorithm is not perfect because it means the extra space is
distributed amongst edge-aligned views only, but it's simple, looks good
and it works.
In i3 the ipc reply will contain a human readable error message, and
this patch replicates that behaviour.
However, that error message is also useful for logging, which this
patch takes advantage of.
E.g. instead of logging errors directly in commands.c/checkargs, it is
fed back to the caller which eventually ends up logging everything with
maximum context available (config.c/read_config).
So instead of logging e.g. "Error on line 'exit'" it will now log:
"Error on line 'exit': Can't execute from config."
