how to fix: ctags null expansion of name pattern "\1"
- by bua
Hi,
As the title points I have problem with ctags when trying to parse user-defined language.
Basically I've followed those instructions.
The quickest and easiest way to do
this is by defining a new language
using the program options. In order to
have Swine support available every
time I start ctags, I will place the
following lines into the file
$HOME/.ctags, which is read in every
time ctags starts:
--langdef=swine
--langmap=swine:.swn --regex-swine=/^def[ \t]*([a-zA-Z0-9_]+)/\1/d,definition/
The first line defines the new
language, the second maps a file
extension to it, and the third defines
a regular expression to identify a
language definition and generate a tag
file entry for it.
I've tried different flags: b,e for regex.
My definition of tag is:
--regex-q=/^[ \t]*[^[:space:]]*[:space:]*:[:space:]*{/\l/f,function/b
When I replace \1 with anything else (ascii caracter set ), It works.
the output is:
(--regex-q=/^[ \t]*[^[:space:]]*[:space:]*:[:space:]*{/my function name/f,function/b)
!_TAG_FILE_FORMAT 2 /extended format; --format=1 will not append ;" to lines/
!_TAG_FILE_SORTED 1 /0=unsorted, 1=sorted, 2=foldcase/

my function name file.q /^.ras.getLocation:{[u]$/;" f
my function name file.q /^.a.getResource:{[u; pass]$/;" f
my function name file.q /^.a.init:{$/;" f
my function name file.q /^.a.kill:{[u; force]$/;" f
my function name file.q /^.asdf.status:{[what; u]$/;" f
my function name file.q /^.pc:{$/;" f
Why \1 doesn't work? (I've tried all 1-9)
