Installation#
pip install 'python-lsp-server[all]'
Debugger: Yes#

Type: boolean
Default: nil
Enable or disable the plugin.
lsp-pylsp-plugins-flake8-config#

Default: nil
A path to a config file that will be the only config file read and used. This will cause Flake8 to ignore all other config files that exist.

Specify the list of error codes you wish Flake8 to report. Similarly to
lsp-pylsp-plugins-flake8-ignore. You can specify a portion of an error code to

lsp-pylsp-plugins-isort-enabled#
Type: boolean
Default: nil
Enable or disable the plugin.
lsp-pylsp-plugins-jedi-completion-enabled#

If enabled, uses fuzzy completion in jedi. Requires pylsp >= 0.32.0 Can hit performance, as well as lsp-mode implements its own fuzzy search on completion items.
lsp-pylsp-plugins-jedi-completion-include-class-objects#
Type: boolean
Default: t
If enabled, adds class objects to completion in order to avoid snippet with init args.
Has no effect if lsp-pylsp-plugins-jedi-completion-include-params is disabled.
Requires pylsp >= 0.33.0
lsp-pylsp-plugins-jedi-completion-include-params#

lsp-pylsp-plugins-mccabe-enabled#
Type: boolean
Default: t
Enable or disable the plugin.
lsp-pylsp-plugins-mccabe-threshold#
Type: number
Default: 15
The minimum threshold that triggers warnings about cyclomatic complexity.
lsp-pylsp-plugins-mypy-config-sub-paths#
Type: lsp-string-vector
Default: nil
Sub paths under which the mypy configuration file may be found.
For each directory searched for the mypy config file, this also searches the sub paths specified here.
lsp-pylsp-plugins-mypy-dmypy#
Type: boolean
Default: nil
If non-nil, use "dmypy run" rather than mypy.
This uses the dmypy daemon and may dramatically improve the responsiveness of the pylsp server, however this currently does not work in live_mode. Enabling this disables live_mode, even for conflicting configs.
lsp-pylsp-plugins-mypy-dmypy-status-file#
Type: string
Default: .dmypy.json
The status file dmypy should use.
This modifies the --status-file option passed to dmypy given dmypy is active.
lsp-pylsp-plugins-mypy-enabled#
Type: boolean
Default: nil
Enable or disable the plugin.
lsp-pylsp-plugins-mypy-exclude#
Type: lsp-string-vector
Default: nil
A list of regular expressions which should be ignored.
The mypy runner wil not be invoked when a document path is matched by one of the expressions. Note that this differs from the exclude directive of a mypy config which is only used for recursively discovering files when mypy is invoked on a whole directory. For both windows or unix platforms you should use forward slashes (/) to indicate paths.
lsp-pylsp-plugins-mypy-live-mode#
Type: boolean
Default: t
If non-nil, type checking is provided as you type.
This writes to a tempfile every time a check is done. Turning off live_mode means you must save your changes for mypy diagnostics to update correctly.
lsp-pylsp-plugins-mypy-overrides#
Type: (vector (choice string boolean))
Default: [t]
A list of alternate or supplemental command-line options.
This modifies the options passed to mypy or the mypy-specific ones passed to dmypy run. When present, the special boolean member True is replaced with the command-line options that would`ve been passed had overrides not been specified. Later options take precedence, which allows for replacing or negating individual default options (see mypy.main:process_options and mypy --help | grep inverse).
lsp-pylsp-plugins-mypy-report-progress#
Type: boolean
Default: nil
If non-nil, report basic progress to the LSP client.
With this option, pylsp-mypy will report when mypy is running, given your editor supports LSP progress reporting. For small files this might produce annoying flashing, especially in with live_mode. For large projects, enabling this can be helpful to assure yourself whether mypy is still running.
lsp-pylsp-plugins-mypy-strict#
Type: boolean
Default: nil
If non-nil, enable the strict option of mypy.
This option often is too strict to be useful.
lsp-pylsp-plugins-preload-enabled#
Type: boolean
Default: t
Enable or disable the plugin.
