auto-format not running on write

[nemoos0]

Summary

The command :format works fine but even if editor.auto-format is set to true the file is not formatted on :write.
Am I missing something?

Reproduction Steps

Set editor.auto-format = true (it should be the default).

Run this to install the python lsp and all its extensions: pip install "python-lsp-server[all]"

Copy/paste this code in a pyton file and open it

def f(x):
    return x



def g(y):
    return y

A warning should appear: E303 too many blank lines.

Running :write does not format the file, but running :format will.

auto-format is not enabled by default for python in the language configuration block:

helix/languages.toml

Lines 472 to 482 in 482cc22

	[[language]]
	name = "python"
	scope = "source.python"
	injection-regex = "python"
	file-types = ["py","pyi","py3","pyw","ptl",".pythonstartup",".pythonrc","SConstruct"]
	shebangs = ["python"]
	roots = []
	comment-token = "#"
	language-server = { command = "pylsp" }
	# TODO: pyls needs utf-8 offsets
	indent = { tab-width = 4, unit = " " }

You can set this in your config to enable formatting through the language server on save:

# ~/.config/helix/languages.toml
[[language]]
name = "python"
auto-format = true
