If the id is defined by another bar it will just use the default id for
the bar. Typically `bar-x`.
If the id command is used multiple times within a bar block, the last
one will 'win'.
When turning a float to a non-float, `get_focused_container` might
return another floating view, causing the active view to be inserted
into the floating list on its workspace instead of the normal child list
which it should. (Since it has `is_floating` as false the resulting
discrepency triggered other bad behaviour eventually leading sway to
crash.)
This patch fixes that by simply checking floating status before making
it a sibling.
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.)
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.)
