history
Project history and usage
fortls is the Fortran Language Server, a Python implementation of the Language Server Protocol for Fortran. It provides editor features such as symbols, hover, signature help, completion, go-to definition, references, rename, diagnostics, and code actions.
Project history
The fortran-lang/fortls repository was created in October 2021. The README says the project was originally based on hansec/fortran-language-server, but later diverged and is now developed independently with additional features and fixes.
The official README also states that fortls has reached a feature-complete and stable maintenance phase while Fortran-lang work explores a newer language server based on LFortran for deeper syntax understanding.
Adoption history
fortls is designed for any editor that supports LSP. The official README names Visual Studio Code, Atom, Sublime Text, Vim/Neovim/gVim, and Emacs integrations, reflecting adoption through editor plugins rather than only command-line invocation.
How it is used
Users install fortls with pip or conda-forge and point an editor's LSP client at the fortls executable. Configuration can be supplied through command-line options or JSON configuration files such as .fortlsrc, .fortls.json, or .fortls at a project root.
Why package nerds care
fortls is significant because it gives Fortran the same LSP packaging shape familiar from newer language ecosystems: a standalone server executable, Python package distribution, conda-forge availability, editor-neutral protocol support, and project-local configuration.
