I've added a reg express for asm (.S) file for exuberant ctags program.
The added express is like this.
--regex-Asm=/^ENTRY\(([a-zA-Z_0-9]+)\)$/\1/m,macro/
--regex-Asm=/\.macro[\t ]+([a-zA-Z_0-9]+)/\1/m,macro/
Using this, I could find tags for lines like .macro addruart, rp, rv, tmp.
(see can't figure out what's wrong with ctag regex for assembly macro extraction)
Today, I found a macro is defined in .h file and is not in the tag file.
So I added the same line for .macro ... in the ~/.ctags for C language too hoping it will just see the assembly macro in .h file.
--regex-C=/\.macro[\t ]+([a-zA-Z_0-9]+)/\1/m,macro/
The definition in .h file is like this:
/*
* Branch according to exception level
*/
.macro switch_el, xreg, el3_label, el2_label, el1_label
mrs \xreg, CurrentEL
cmp \xreg, 0xc
b.eq \el3_label
cmp \xreg, 0x8
b.eq \el2_label
cmp \xreg, 0x4
b.eq \el1_label
.endm
But looks like it doesn't work. How can I do it?
By default, ".h" is associated with C++ parser, not C parser.
Therefore, the command line should be:
--regex-C++=/\.macro[\t ]+([a-zA-Z_0-9]+)/\1/m,macro/
Such associations are called mapping. --list-maps option is for showing the mapping.
$ ctags --list-maps | grep '\.h\>'
