Subject: tilde syntax
Date: Thu, 4 Jan 2024 14:31:53 -0800 [thread overview]
Message-ID: <625e7ef5-be1f-4b5d-bb2a-f71634d151cf@eastlink.ca> (raw)
local zsh_case='(#i)' # insensitive
# Depending on options: zsh_case=''
# Where input is some directory name, possibly incomplete and
matches are looked for:
subdirs=( $1*(/N) )
subdirs=( (#i)$1*(/N) )
subdirs=( $~zsh_case$1*(/N) ) # This works: but tilde must follow
first dollar sign
The first two seem intuitive, but the 3d, what does the tilde really
do? It has to be there, but one might expect '$zsh_case' to just
substitute and all's well. I used to understand this, I remember Roman
explaining it, but I can't remember and my notes are sketchy. The tilde
turns globing into pattern matching, yes? But '(#i)' works if literal,
it's not mistaken for a glob pattern so why should the use of a variable
change anything? Again, pardon, I used to know this.
