Description edit
There are a number of different options when it comes to matching data against some form of pattern. In Tcl, you might be interested in:- simple string replacements, as in string map (which, in this case, patterns are classes of literal characters)
- matching file names: glob
- string match which are glob-style patterns
- regexp/regsub which are regular expressions
- searching for patterns in lists: lsearch
- switch / case
- array get/names/unset (which support string match type patterns)
- chan names (which supports string match type patterns)
- dict filter/key/values (which support string match type patterns)
- file channels (which supports string match type patterns)
- info commands/functions/globals/locals/procs/vars (which support string match type patterns)
- auto_import which supports namespace import patterns
- auto_mkindex which supports glob patterns
- namespace children
- namespace export
- namespace forget
- namespace import
- registry keys/values (which support string match type patterns)
- the Expect extension, which makes use of regular expressions
- algebraic types or unification
