Code editing

Open a source file as you would a note. Accent picks syntax highlighting from the file type and indents new lines as you type. It wraps long lines by default, but Alt+Z toggles wrapping for the current tab.

Navigate code

Open the Outline pane with Ctrl+Shift+W to jump to a declaration. The outline can use Accent’s index while a language server is starting or unavailable. When a server reports foldable blocks, click a gutter chevron or use Ctrl+Shift+[ and Ctrl+Shift+].

Use Shift+Alt+Up or Shift+Alt+Down to add carets on neighbouring lines. Alt+J adds a caret at the next match, and Ctrl+Shift+L selects all matches. For a bird’s-eye view, enable Minimap in Preferences or run Toggle Minimap.

Language servers

Install a language server on the computer that holds your vault. Accent starts a supported server when you open a file. For example, it tries rust-analyzer for Rust, pyright or pylsp for Python, texlab for LaTeX and tinymist for Typst. On a remote vault, install the server on the host. The Flatpak starts a local vault’s servers inside its sandbox, so it does not find the ones installed on your computer.

Completion appears as you type, or you can request it with Ctrl+Space. Choose a suggestion with the arrow keys, then press Tab or Return. Hover over a name for details, or use F12, Ctrl+Shift+Return, or Ctrl+click to go to its definition. The Info pane shows references, while the status bar’s diagnostic count toggles inline messages. Use Quick Fix… (Alt+Return) for a diagnostic’s fixes or Source Action… for actions on the file.

For Python, choose Python Environment in the Code pane to use the vault’s interpreter for analysis, debugging and notebooks. A running program or kernel keeps its interpreter until restarted. Project settings for Pyright’s virtual environment take precedence for language analysis.

To choose a different server, set its command in ~/.config/accent/config.toml:

[lsp.servers]
python3 = ["pylsp"]

You can also set a server for one vault under [vaults."/path/to/vault".lsp.servers]. Without a server, you can still edit, search, and use the indexed outline.

LaTeX and SyncTeX

Accent edits .tex files, and texlab adds language features if it is installed. Build the document with SyncTeX enabled, for example latexmk -pdf -synctex=1 paper.tex. Then use Show in PDF from the .tex tab’s menu to find the line under the caret in the built PDF. To go the other way, Ctrl+click the PDF page or choose Go to Source from its menu.

Both commands need a matching local build with .synctex or .synctex.gz data. They are unavailable for remote vaults and for PDFs whose pages you have rearranged since building.

Typst

Accent edits .typ files with syntax highlighting, and the Outline lists their headings even without a language server. With tinymist installed, it also completes labels and citations, shows errors and builds the PDF whenever you save. The PDF goes beside the main document, the file that includes the one you are editing, so saving a chapter rebuilds the whole document. Open the PDF from the Files pane once, and it reloads after every build. While the main document does not compile, the status bar names it over the tabs of its files. Typst writes no SyncTeX data yet, so Show in PDF and Go to Source stay greyed for its documents.

Lean

Open a .lean file in a Lean project with lake serve available. The Code pane shows goals and the expected type at the caret, while a bar in the gutter shows checking progress. Type an abbreviation such as \to, then press Tab to insert →. These abbreviations also work while the server is still starting. After rebuilding imports, run Restart File in Language Server from the command palette.

To use Helix, Vim or another terminal editor for text files, choose it in Preferences.
