Update .config/helix/languages.toml.config/helix/languages.toml to use tinymist.

[language-server.tinymist]

command = "tinymist"

[[language]]

name = "typst"

language-servers = ["tinymist"]

[language-server.tinymist]

command = "tinymist"

[[language]]

name = "typst"

language-servers = ["tinymist"]

[language-server.tinymist]

command = "tinymist"

[[language]]

name = "typst"

language-servers = ["tinymist"]

[language-server.tinymist]

command = "tinymist"

[[language]]

name = "typst"

language-servers = ["tinymist"]

Default Preview Feature and Background Preview Feature are suitable in helix.

There is a way in Neovim, but you cannot invoke related commands with arguments by :lsp-workspace-command in helix. As a candidate solution, assuming your having following directory layout:

├── .helix

│   └── languages.toml

└── main.typ

├── .helix

│   └── languages.toml

└── main.typ

├── .helix

│   └── languages.toml

└── main.typ

├── .helix

│   └── languages.toml

└── main.typ

You could create .helix/languages.toml in the project folder with the following contents:

[language-server.tinymist.config]

typstExtraArgs = ["main.typ"]

[language-server.tinymist.config]

typstExtraArgs = ["main.typ"]

[language-server.tinymist.config]

typstExtraArgs = ["main.typ"]

[language-server.tinymist.config]

typstExtraArgs = ["main.typ"]

Then all diagnostics and autocompletion will be computed according to the main.typmain.typ.

Note: With that configuration, if you’re seeing a file that is not reachable by main.typmain.typ, you will not get diagnostics and autocompletion correctly in that file.

To configure the language server, edit the language-server.tinymistlanguage-server.tinymist section. For example, if you want to export PDF on typing and output files in $root_dir/target$root_dir/target directory:

[language-server.tinymist]

command = "tinymist"

config = { exportPdf = "onType", outputPath = "$root/target/$dir/$name" }

[language-server.tinymist]

command = "tinymist"

config = { exportPdf = "onType", outputPath = "$root/target/$dir/$name" }

[language-server.tinymist]

command = "tinymist"

config = { exportPdf = "onType", outputPath = "$root/target/$dir/$name" }

[language-server.tinymist]

command = "tinymist"

config = { exportPdf = "onType", outputPath = "$root/target/$dir/$name" }

To enable a live preview you can use the preview.backgroundpreview.background:

[language-server.tinymist]

command = "tinymist"

config = { preview.background.enabled = true", preview.background.args = ["--data-plane-host=127.0.0.1:23635", "--invert-colors=never", "--open"] }

[language-server.tinymist]

command = "tinymist"

config = { preview.background.enabled = true", preview.background.args = ["--data-plane-host=127.0.0.1:23635", "--invert-colors=never", "--open"] }

[language-server.tinymist]

command = "tinymist"

config = { preview.background.enabled = true", preview.background.args = ["--data-plane-host=127.0.0.1:23635", "--invert-colors=never", "--open"] }

[language-server.tinymist]

command = "tinymist"

config = { preview.background.enabled = true", preview.background.args = ["--data-plane-host=127.0.0.1:23635", "--invert-colors=never", "--open"] }
