daec63e5e6 Replace %% in command lists (by copying them) for template arguments , 
this means they can be used with {} as well. Also make argument
processing from an existing vector preserve commands. GitHub issue 2858.

03b83a5a34 Key bindings steal a reference to the command instead of adding their 
own, it was correct not to add a reference when parsing, but the
bind-key then needs to add one.

d3c5202f50 Allow strings to span multiple lines - newlines and any leading 
whitespace are removed, as well as any following comments that couldn't
be part of a format. This allows long formats or other strings to be
annotated and indented.

b3782d2dc8 Instead of using a custom parse function to process {}, treat it as a 
set of statements and parse with yacc, then convert back to a string as
the last step. This means the rules are consistent inside and outside
{}, %if and friends work at the right time, and the final result isn't
littered with unnecessary newlines.

187277eaad Add helpers for the simple case of parse string and add to command queue. 2020-04-13 18:59:41 +00:00

34804f2709 When parsing strings, put all commands in one group even if there are 
newlines. This means that for example bind q { a \n b } and bind q "a ;
b" are the same. Also log commands in different groups separated by ;;
rather than ; (a command list like this should never be user visible).

f4c7141f5d Do not lazily use BUFSIZ for "I don't care what size" when building 
strings because it is only guaranteed to be 256 bytes and even the
default 1024 is not always enough. Reported by Gregory Pakosz.

45203582ff A couple of minor parser changes around conditions: 1) only treat #{ 
specially after a condition, otherwise as a comment (which is more as
most people expect) 2) allow formats to be quoted after a condition.

900238a306 yacc(1) copies its union so it is not a good place to store

7dced37673 Use VIS_CSTYLE for the arguments and add the missing escapes it can 
generate to the parser.

c17edd594e 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.

a4424fbebf Support \ooo escapes, from Avi Halachmi. 2019-05-29 10:08:36 +00:00
nicm
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.

processing code.

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.
