Editor Adapter Instructions

When to Use a File vs Registry

Most editors are defined as registry entries in lib/adapters.sh — no adapter file needed. Only create an adapter file in adapters/editor/ for editors that need custom behavior beyond what the standard/terminal builders provide (see nano.sh for an example).

Adding a Standard Editor (Registry)

Add a line to _EDITOR_REGISTRY in lib/adapters.sh:

yourname|yourcmd|standard|EditorName not found. Install from https://...|flags

Format: name|cmd|type|err_msg|flags

• type: standard (GUI app) or terminal (runs in terminal)
• flags: comma-separated — workspace (supports .code-workspace), background (terminal bg)

Adding a Custom Editor (File Override)

Create adapters/editor/<name>.sh implementing:

#!/usr/bin/env bash
# EditorName adapter

editor_can_open() {
  command -v editor-cli >/dev/null 2>&1
}

editor_open() {
  local path="$1"
  if ! editor_can_open; then
    log_error "EditorName not found. Install from https://..."
    return 1
  fi
  editor-cli "$path"
}

File-based adapters take precedence over registry entries of the same name.

Also update:

• README.md (setup instructions)
• Completions: run ./scripts/generate-completions.sh (registry names are picked up automatically; the files under completions/ are generated and checked in CI)
• Help text in lib/commands/help.sh (_help_editor)
• Editor list (Setup editors) in docs/configuration.md

Contract & Guidelines

• Required functions: editor_can_open (probe via command -v), editor_open <path>.
• Quote all paths; support spaces. Avoid changing PWD globally—no subshell needed (editor opens path).
• Use log_error with actionable install guidance if command missing.
• Keep adapter lean: no project scans, no blocking prompts.
• Naming: file/registry name = tool name (zed → zed flag). Avoid uppercase.
• Update: README editor list, docs/configuration.md editor list, help text, then regenerate completions.
• Fallback behavior: if editor absent, fail clearly; do NOT silently defer to file browser.
• Inspect function definition if needed: declare -f editor_open.
