Subject: [PATCH] Handle comments in the C expression parser
Date: Tue, 13 Feb 2001 20:07:00 -0000
Message-id: <x78zn96h7n.fsf@dynamic-addr-83-177.resnet.rochester.edu>
X-SW-Source: 2001-02/msg00194.html

This patch adds C-style comment handling to the expression parser.

That way, we can add comments to output of various places, and still
be able to paste it back in.
(gdb) p 5 /* / */ / 3
$1 = 1
(gdb) p 5 /* / */ / 3 */* 333333 blah */ 2
$2 = 2
(gdb) p 5 /* / */ / 3 */* 333333 blah */ 2
$3 = 2
(gdb) p 5 /* / */ / 3 */* 333333 blah */ 2
$4 = 2
(gdb) p 5 /* / */ / 3 */* 333333 blah *// 2
A parse error in expression, near ` 2'.
(gdb) p 5 /* / */ / 3 */* 333333 blah *// 2
A parse error in expression, near ` 2'.
(gdb) p 5 /* / */ / 3 */* 333333 blah */2/ 2
$5 = 1
(gdb)


(The parse errors are because, if you look closely, it's really 5 / 3
* / 2, so the parse error is correct. )

        * c-exp.y : Handle C style comments in expression parser,
        ignoring them.
