README

pi-slash-suggest

pi-slash-suggest makes Pi's slash menu available in the middle of the editor, not only at the start of a line. Type normal text, press /, pick a command, and the completed slash token gets a persistent highlight.

Install

pi install npm:pi-slash-suggest

That is the only required step. Pi loads the TypeScript extension directly; there is no build step and no Pi core patch.

Try this first

Open Pi and type text before the slash:

test slash /wa

The slash menu opens mid-line. Accept a suggestion with Tab or →:

test slash /mattpocock-skills:wayfinder

Keep typing. The accepted slash token stays highlighted while the rest of the line remains normal text.

How it works

Pi's native editor only exposes the slash menu in restricted contexts. This extension keeps Pi core untouched and changes behavior at the extension boundary:

A custom editor relaxes the slash-menu gates for mid-text / tokens.
A provider wrapper gives the base autocomplete provider a line-start view of the active token.
Completion insertion is owned by the wrapper for mid-text tokens, so /value is inserted with one separating space.
A pure highlight pass marks completed slash tokens when whitespace or end-of-line follows them.

At line start, Pi's native slash behavior stays unchanged.

Slash menu keys

Mid-text, the menu keys are intentionally conservative:

Key	Action
`Tab`	Accept the selected suggestion
`→`	Accept the selected suggestion
`Enter`	Close the menu without accepting or submitting

At line 0, Pi's native keys stay unchanged.

Implementation map

File	Responsibility
`index.ts`	Extension entry point. Registers the custom editor and provider wrapper.
`editor.ts`	`SlashSuggestEditor`; cursor-line, word-boundary, slash-context, highlight, and key handling.
`provider.ts`	Autocomplete provider wrapper and mid-text completion insertion.
`highlight.ts`	Pure string transform for slash-token highlighting.

Test

Tests live in the parent pi-extensions repo:

bun test tests/pi-slash-suggest.test.ts   # unit
bun run test:integration                  # headless Pi

Manual check: open Pi, type hello /, accept a suggestion, then confirm the accepted token remains highlighted.

Compatibility and risks

The editor overrides TypeScript-private methods. A Pi upgrade can break them.

Confirmed against:

Pi 0.85.1 Homebrew runtime
Pi 0.84.3 pinned types

Fallback: a one-line core patch in Pi TUI editor.js — remove the / exclusion in setAutocompleteTriggerCharacters and relax isSlashMenuAllowed.

Key rewriting matches raw input sequences. User-rebound TUI keybindings are ignored in v1.
