Rewrite Rules:

rewrite is an object where keys are regular expressions and values are rewrite rules if the expression matches. Rules may contain references to captures of the expression.

Regular expression and replacement follow ECMAScript rules (formal definition).

An expression must match fully to trigger the replacement; if no expression matches, the format output is left unchanged.

Invalid expressions (e.g., mismatched parentheses) are ignored.

Example 1:

"dwl/window": {
    "format": "{title}",
    "max-length": 50,
    "rewrite": {
       "(.*) - Mozilla Firefox": "🌎 $1",
       "(.*) - vim": " $1",
       "(.*) - zsh": " [$1]"
    }
