* © 2009-2012 Michael Stapelberg and contributors (see also: LICENSE)

*
|

* commands_parser.c: hand-written parser to parse commands (commands are what
|
||||
* you bind on keys and what you can send to i3 using the IPC interface, like
|
||||
* 'move left' or 'workspace 4').
|
||||
*
|
||||
* 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).
