ReFilter

Filter strings by first cutting out a region (include) and then selectively remove (exclude) from that region.

I often use this in my programs to allow a user to specify what files to process and the have some control over what to exclude.

--re-include and --re-exclude is a suggestion for parameters to use with getopt.

@safe

struct ReFilter {

import std.regex : Regex, regex, matchFirst;;

Regex!char includeRe;

Regex!char[] excludeRe;

this(string include, string[] exclude);

bool match(string s);

}

Constructors

this this(string include, string[] exclude): The regular expressions are set to ignoring the case.

assert(["foo", "foobar", "foo smurf batman", "batman", "fo",
        "foo mother"].filter!(a => r.match(a)).array == [
        "foo", "foo mother"
        ]);
