LFortran LSP

VSCode extension for integrating with LFortran's language server. The extension is intended to be extremely lightweight and delegates all the heavy lifting to the language server.

Building and Installation

# Clone the repository if you have not already:
git clone https://github.com/lfortran/lfortran-lsp.git

cd lfortran-lsp

# If you already had it cloned, update your repo:
git pull origin main

# Install the NPM dependencies:
npm install

# Bundle the package (lfortran-lsp-0.0.1.vsix):
npx vsce package

# Uninstall any older version of the extension from VSCode:
code --uninstall-extension lcompilers.lfortran-lsp

# Install the package you just created:
code --install-extension lfortran-lsp-0.0.1.vsix

Usage

Once you have installed the extension, it should begin working immediately when a Fortran file is opened or edited. More specifically, any time a file is opened or edited with one of the following file extensions, this VSCode extension will be activated: .f; .for; .f90; .f95; .f03.

Code Validation

LFortran will automatically check a document for syntactic and semantic errors and warn about potential issues. Errors will be highlighted and described in the Problems terminal (View -> Problems).

Configuration

You may configure the extension by clicking the Extensions tab, followed by clicking the gear icon on the bottom-right of the lfortran-lsp list item, and lastly by clicking the Settings menu item. Most of the settings are common to all workspaces but the compiler flags may be modified at the resource level.
