Migrating from ruff-lsp
While ruff server
supports the same feature set as ruff-lsp
, migrating to
ruff server
may require changes to your Ruff or language server configuration.
Note
The VS Code extension settings include documentation to indicate which
settings are supported by ruff server
. As such, this migration guide is primarily targeted at editors that lack
explicit documentation for ruff server
settings, such as Helix or Neovim.
Unsupported Settings
Several ruff-lsp
settings are not supported by ruff server
. These are, as follows:
format.args
ignoreStandardLibrary
interpreter
lint.args
lint.run
path
Note
Some of these settings, like interpreter
and path
, are still accepted by the VS Code
extension. path
, in particular, can be used to specify a dedicated binary to use when
initializing ruff server
. But the language server itself will no longer accept such settings.
New Settings
ruff server
introduces several new settings that ruff-lsp
does not have. These are, as follows:
configuration
configurationPreference
exclude
format.preview
lineLength
lint.select
lint.extendSelect
lint.ignore
lint.preview
Several of these new settings are replacements for the now-unsupported format.args
and lint.args
. For example, if
you've been passing --select=<RULES>
to lint.args
, you can migrate to the new server by using lint.select
with a
value of ["<RULES>"]
.
Examples
Let's say you have these settings in VS Code:
After enabling the native server, you can migrate your settings like so:
{
"ruff.configuration": "~/.config/custom_ruff_config.toml",
"ruff.lineLength": 80,
"ruff.lint.select": ["E", "F"]
}
Similarly, let's say you have these settings in Helix:
[language-server.ruff.config.lint]
args = "--select=E,F --line-length 80 --config ~/.config/custom_ruff_config.toml"
These can be migrated like so:
