Layout

The finder by default starts in fullscreen mode. You can make it start below the cursor with fullscreen=False option. Also, with the height argument you can limit the window height.

pzp(candidates=range(0, 1000), fullscreen=False, height=20)

You can choose between the following layout using the layout option.

• default Display from the bottom of the screen
• reverse Display from the top of the screen
• reverse-list Display from the top of the screen, prompt at the bottom

Search syntax

The finder starts in "extended-search mode" where you can type in multiple search terms delimited by spaces. e.g. ^music .mp3$ sbtrkt !fire

Token	Match type	Description
t1 t2	tokens-match	Items that include t1 and t2
'star wars	line-match (not-splitted)	Items that include star wars
^music	prefix-exact-match	Items that start with music
.py$	suffix-exact-match	Items that end with .py
!fire	inverse-exact-match	Items that do not include fire
!^music	inverse-prefix-exact-match	Items that do not start with music
!.py$	inverse-suffix-exact-match	Items that do not end with .py

Key/Event Bindings

keys_binding argument allows you to bind one or more keys to one action. You can use it to customize key bindings or implementing custom behaviors.

try:
    item = pzp(
        candidates=candidates,
        keys_binding={
            "custom-action": ["ctrl-o"],
            "exclamation": ["!"]
        },
    )
    print(item)
except CustomAction as action:
    print(action.action)
    print(action.selected_item)
