Dynamic Objects #

I am trying to match those tags that I have created for each topic entry ^# \s\w*\s#$

But some of them are multiword , so I need to have a custom character class such as [A-Za-z\s]

Upon using that configuration I can get is

$ ctags --options=NONE --options=./aidan.ctags -f ./tags head.aidan
ctags: Notice: No options will be read from files or environment
$ cat tags

Is not matching against those multiword tags , despite this regex been correct (I have used it on regex101.com and it works

Should you want to check against the actual file

curl https://termbin.com/a345

[masatake]

In ctags, [\s] matches \ or s. For matching whitespace, use [ \t] or [[:space:]]. So the option should be:

--regex-aidantags=/^#\s([A-Za-z0-9[:space:]]*)\s#$/\1/t/

(the pattern had a typo. edited).

Thank you , it worked
