Release v7.20.0 · kdeldycke/click-extra

Add MultiChoice to click_extra.types: a Click ParamType for comma-separated multi-pick from a fixed set of values, the pick-many counterpart to click.Choice.
Extend the --show-params table with seven new columns (Is flag, Flag value, Is bool flag, Multiple, Nargs, Prompt, Confirmation prompt).
Add the --columns option (ColumnsOption, @columns_option) for SQL SELECT-style column selection on both --show-params and the standalone click-extra show-params subcommand.
Add a click:tree Sphinx directive that walks a Click command tree and expands into a summary table plus one {click:run} --help block per command. MyST-only.
Fix click-extra show-params ignoring the top-level --table-format option and rendering its default as the enum name instead of the kebab-case ID.
Fix click-extra show-params and click-extra man resolving auto-generated environment variables as empty; the envvars column now matches what Click reads at runtime.
Fix the MkDocs plugin stripping ANSI escape codes but rendering no colors: it now generates the ANSI Pygments stylesheet and registers it through extra_css, so the -Ansi-* classes it emits are styled.
Drop duplicate and dead CSS classes from ANSI HTML rendering: compound tokens like Token.Ansi.Bold.Cyan now emit -Ansi -Ansi-Bold -Ansi-Cyan instead of repeating -Ansi-Bold and adding an unstyled -Ansi-Bold-Cyan.
