e252984993 If only one of -x or -y is given, use the calculated size for the
other. Also fix some warnings. Pointed out by Ben Boeckel.

17bc11bd15 yacc(1) copies its union so it is not a good place to store
TAILQ_HEADs. Allocate them instead. Found from a problem reported by
sthen@.

1a3a973bd0 Allow % strings that are all numbers or %s, and fix a double free. Both
reported by George Nachman, GitHub issues 1765 and 1766.

e4eec92852 No longer need to reduce line number by one. 2019-05-30 13:12:35 +01:00

75d112c484 The line number needs to be updated only after the \n is processed by
the parser, so store a flag and update it next time around. Also each
new line needs its own shared data.

6b332127ca Add an additional {} syntax for defining strings in the configuration
file, making it much tidier to define commands that contain other tmux
or shell commands (like if-shell). Also tweak bind-key to expect a
string if it is only given one argument, so {} can be used with it as
well. From Avi Halachmi.

6dee409981 Some other platforms doesn't support fmemopen(3) (not unexpectedly), so
don't use it - since we only use getc/ungetc on the file anyway it is
easy not to.

f8d3d247d8 Merge cmd_list_parse into cmd-parse.y so it can use the new alias
processing code.

f3e01ecc42 Fix line numbers - commands are added after the line ends so they need to
get line - 1.

27bfb56ad5 Break the argument escaping code into a separate function and use it to
escape key bindings in list-keys. Also escape ~ and ; and $ properly.

723010ba72 Replace the split parser code (cfg.c and cmd-string.c) with a single
parser using yacc(1). This is a major change but is clearer and simpler
and allows some edge cases to be made more consistent, as well as
tidying up how aliases are handled. It will also allow some further
improvements later.

Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).

The only syntax change I am aware of is that #{} outside quotes or a
comment is now considered a format and not a comment, so #{ is now a
syntax error (notably, if it is at the start of a line).

This also adds two new sections to the man page documenting the syntax
and outlining how parsing and command execution works.

Thanks to everyone who sent me test configs (they still all parse
without errors - but this doesn't mean they still work as intended!).

Thanks to Avi Halachmi for testing and man page improvements, also to
jmc@ for reviewing the man page changes.
