That’s a tricky problem to solve (sort of).
In the C grammar there are rules to mark #if 0 … #endif as commented.
This is a little more complex than so, as it needs to handle nesting
of such preprocessor instructions, the #else case, etc. It also has a
general #if(n?def)? match so that an #else belonging to an outer #if/
#else/#endif is not mistaken as belonging to the #if 0/#endif.
Between the preprocessor conditionals, the C grammar includes $base,
meaning full Objective-C, if that is the chosen language.
But, in Objective-C methods are only matched between
@implementation / @end. So it is not enough to include $base in the C
grammar, it really wants something like $parent (referring to the
rules which were active in the parent scope), though this
functionality does not presently exist.
One fix could be to always match methods (in the Objective-C
grammar), another would be to not care about matching #if(n?def)? in
the root scope -- I am actually not entirely sure we need to track
it, since #else binds to the innermost conditional. But I’ll have to
ponder this before making any changes to the grammar.
