[vim/vim] Hyphenated usernames not highlighted correctly in sudoers files (Issue #18963)
StephenWall
StephenWall created an issue (vim/vim#18963)Steps to reproduce
Use vim to edit a sudoers file that has hyphenated username in it, such as www-data (the apache username on Ubuntu 24.04 LTS).
Note that the hyphenated usernames are not colored. This would also occur with usernames containing digits.
Ubuntu has NAME_REGEX setting of "^[a-z][-a-z0-9_]*$?$", so a trailing "$" is also allowed.
Expected behaviour
I expect "www-data" to be highlighted the same as any non-hyphenated username.
I achieved this locally by changing vim91/syntax/sudoers.vim to have \l[a-z0-9-]* instead of \l\+ in all syn match statements that had UserName, Group, or UserNetgroup in the name. Note that doesn't allow the trailing dollar sign.
