Configuration

All settings live in a single global JSON file:

~/.config/e/config.json

Press ⌘, for a graphical settings page covering the common options. It's a two-pane dialog: pick a category (Appearance, Editor, On Save, Panels, Laravel, Agents) in the sidebar, or type in the search box to filter settings across every category. Changes are saved automatically; the Open config.json link in the footer jumps to the raw file (with advanced sections like agents, snippets and keybindings), which is created on first use.

}

API keys for Anthropic, OpenAI, Gemini and Grok are not in this file: they are entered in Settings → Agents and kept in the macOS Keychain (elsewhere ~/.config/e/secrets.json, mode 0600). See AI Agents.

Panel layout (sidebar_side, agent_side) is read at startup — restart e after changing it. By default the explorer/Git sidebar is on the left and the agent panel on the right; set them to swap sides.

EditorConfig

If a project has an .editorconfig, e honours it per file, layered over the global settings above:

• indent_size / tab_width → the buffer's tab width.
• trim_trailing_whitespace → overrides trim_on_save for matching files.
• insert_final_newline → ensures a single trailing newline on save.

The usual resolution rules apply: files are read from the file's directory upward, stopping at root = true, and a nearer file (or a later matching section) wins. Globs support *, **, ? and {a,b}.

Keybindings

Every action is a named command; rebind any of them in the keybindings section. See Keybindings for the syntax and the full command list.

Themes

e ships seven themes — its own Dark and Light, Tokyo Night, Darcula, Material (Oceanic), Nord and Palenight — each a full palette: the UI chrome, the editor (background, gutter, cursor, selection, current line), the syntax colours, and the error/warning/success colours used across panels. Pick one from the cards in Settings → Appearance → Theme; the choice is saved to config.json as theme and the whole window re-themes at once. F8 switches between the dark theme in use and Light, and back.

Zoom & word wrap

• ⌘= / ⌘- change the editor font size for the session; ⌘0 resets to your configured font_size.
• ⌥Z toggles soft word wrap.

Agents

See AI Agents for the agents section (default agent and the list of configurable agents).
