NAME

PLS - Perl Language Server

DESCRIPTION

The Perl Language Server implements a subset of the Language Server Protocol for the Perl language. Features currently implemented are:

• Go to definition (for packages, subroutines, and variables)

• Listing all symbols in a document

• Hovering to show documentation

• Signature help (showing parameters for a function as you type)

• Formatting

• Range Formatting

• Auto-completion

• Syntax checking

• Linting (using perlcritic)

• Sorting imports

OPTIONS

This application does not take any command line options. The following settings may be configured using your text editor:

perl.inc - a list of paths to include in @INC

You can use $ROOT_PATH to stand in for your project's root directory, to allow for configuration to work the same for multiple directories of the same project. This is useful if you use SVN and check out each branch to a different directory.

perl.pls - path to pls

Configure this option if pls is not available in your path.

perl.cwd - the working directory to use for pls

perl.perltidyrc - the location of your .perltidyrc file.

Defaults to ~/.perltidyrc if not configured.

perl.perlcritic.enabled - whether to enable linting using perlcritic.

perl.perlcritic.perlcriticrc - the location of your .perlcriticrc file.

Defaults to ~/.perlcriticrc if not configured.

You may configure a .plsignore file in your project's root directory, with a list of Perl glob patterns which you do not want pls to index.

By default, pls will index everything that looks like a Perl file, with the exception of .t files.

CAVEATS

pls has not been tested with editors other than Visual Studio Code.

NOTES

Install the fractalboy.pls extension to Visual Studio Code in order to use this language server.
