This fixes problems with the Oracle JRE7, which checks the current focus after
receiving WM_TAKE_FOCUS and just does nothing when the focus is on one of its
windows. Hopefully it doesn’t introduce any regressions :).
On the rationale of using a custom parser instead of a lex/yacc one, see this
quote from src/commands_parser.c:
We use a hand-written parser instead of lex/yacc because our commands are
easy for humans, not for computers. Thus, it’s quite hard to specify a
context-free grammar for the commands. A PEG grammar would be easier, but
there’s downsides to every PEG parser generator I have come accross so far.
This parser is basically a state machine which looks for literals or strings
and can push either on a stack. After identifying a literal or string, it
will either transition to the current state, to a different state, or call a
function (like cmd_move()).
Special care has been taken that error messages are useful and the code is
well testable (when compiled with -DTEST_PARSER it will output to stdout
instead of actually calling any function).
During the migration phase (I plan to completely switch to this parser before
4.2 will be released), the new parser will parse every command you send to
i3 and save the resulting call stack. Then, the old parser will parse your
input and actually execute the commands. Afterwards, both call stacks will be
compared and any differences will be logged.
The new parser works with 100% of the test suite and produces identical call
stacks.
The problem was that the workspace was considered empty for a brief period of
time when entering floating mode. This happened when you assigned Gimp to a
workspace which is not in use yet.
With this commit, i3 will now use either $XDG_RUNTIME_DIR/i3 (XDG_RUNTIME_DIR
is only writable by the user, so this is not a problem) or a secure temporary
location in /tmp, following the pattern /tmp/i3-<user>.XXXXXX
Fixes: #585
This commit fixes the problem of i3 wrongly grabbing/interpreting (!) some key
bindings. Basically, when you have, say, "bindsym Mod1+4 workspace 4", but you
also have "bindsym Mod1+semicolon focus right" (both are default), and your
keyboard layout has semicolon on Mode_switch + 4, the "workspace 4" keybinding
was shadowed by the "focus right" keybinding, because that also resolves to
semicolon.
So, from now on, i3 will only consider column 0 and 1 for normal bindings and
column 2 and 3 for bindings using Mode_switch (columns as seen in xmodmap
-pke).
