LSP-julia

A plugin for the LSP client in Sublime Text with support for the Julia language server.

Requirements & Installation

The following should be installed:

• Julia 1.10, 1.11, or 1.12
• The Julia package from Package Control
• The LSP and LSP-julia packages from Package Control
• Optionally the Terminus package from Package Control for a basic Julia REPL integration and the ability to run code blocks with a key binding

[!NOTE] If the julia executable is not in your PATH, you need to provide the full path to the executable in the LSP-julia package settings.

When a Julia file is opened for the first time after installing LSP-julia, the language server will automatically be installed with the Julia package manager. This can take a few minutes.

Features

The Julia language server supports most of the standard LSP features like auto-completion, documentation on hover, goto definition, and diagnostics (linting).

[!IMPORTANT] Most features require that a folder was opened in Sublime Text and don't work in single file mode.

LSP-julia provides additional commands which are available from the command palette:

Command label	Key binding	Description
LSP-julia: Change Current Environment	none	Select the Julia project environment you are working in. The packages from this environment are used by the language server to provide autocomplete suggestions and for diagnostics/linting. Dependent on the number of packages, it might take a while for the server to do a package indexing process in the background, after switching to a different environment.
LSP-julia: Documentation	none	Search the Julia documentation[1] and open the results in a tab. You can also right-click on a word in a Julia file and select “Show Documentation” from the context menu to open the corresponding documentation page.
LSP-julia: Open Julia REPL in Panel[2]	none	Open a Julia REPL, started in the directory of the active file, or focus if already running.
LSP-julia: Open Julia REPL in Tab[2]	none	Same as above, but use a normal tab instead of the bottom panel for the REPL.
LSP-julia: Select Code Block	none	Select the function or code block at the current cursor position. For multiple active cursors, only the topmost cursor position is taken into account.
LSP-julia: Run Code Block[2]	Alt+Enter	If text is selected, run it in a Julia REPL. Otherwise, run the code block containing the current cursor position and move curser to the next block.
LSP-julia: Run Code Cell[2]	Alt+Shift+Enter	If text is selected, run it in a Julia REPL. Otherwise, run the code cell containing the current cursor position and move curser to the next cell. Code cells are signalized with a specially formatted comment at the start of a line: ##, #%% or # %%.

[^1]: The documentation pages are dynamically generated from docstrings in Julia base, the standard library and in Julia packages, not from the official documentation on the Julia website. [^2]: Only available if you have the Terminus package installed.

To add or adjust key bindings for the commands, run Preferences: Key Bindings from the command palette and modify the user file on the righthand side. For an example refer to the Default.sublime-keymap file in this repository, and for the command names from this package see LSP-julia.sublime-commands.

Troubleshooting

I have deleted or cleaned up my .julia directory. Now the language server doesn't start anymore.

Delete the LSP-julia folder at the following location: * on Windows: %LocalAppData%/Sublime Text/Package Storage/LSP-julia * on Linux: ~/.cache/sublime-text/Package Storage/LSP-julia * on macOS: ~/Library/Application Support/Sublime Text/Package Storage/LSP-julia

Then restart Sublime Text and open a Julia file to re-install the language server.
