Fortran developer tools
All tools run locally in your browser. Nothing is sent to a server. Outputs are starting points: review them against the official documentation for your versions.
.fortls configuration generator
Only options you enable are written. Leave blank to use fortls defaults. One path per line (or comma-separated).
fortls config checker
Paste a config. Comments (JSONC) are accepted. Checks syntax, key names and value types against options known to this tool — not full semantics.
fpm.toml generator
Creates a starter manifest for the Fortran Package Manager.
Config options change between releases; see the official fortls documentation and fpm documentation. Provided as-is without warranty (see Terms).
