Issue with the formatters Prettier and Ruff. helix_view::document [ERROR] Formatter error: [error] No parser could be inferred for file "{file}"

[richardhttps]

Manual formatting with Prettier and Ruff are not working in the Helix editor. Attached is my languages.toml.
Things to know:

• The binaries of Prettier and Ruff are already in /usr/bin/
• The formatters work when invoked in the terminal, eg: cat test.css | prettier --stdin-filepath test.css
• The files have proper extensions ".py" ".css" ".js", etc.
• The files are already saved to disk.
• Other formatters are working
• Helix's version is 25.01.1
• Helix's log shows this error line:

helix_view::document [ERROR] Formatter error: [error] No parser could be inferred for file "{file}".

The {file} syntax is not implemented so the formatter is being called like:

cat test.css | prettier --stdin-filepath {file}

Instead you can configure the formatter with a dummy file name like

formatter = { command = "prettier", args = ["--stdin-filepath", "test.css"] }
