Release Notes

google/yamlfmt (google/yamlfmt)

v0.18.1

Compare Source

The previous fix for pre-commit was poorly done. The default experience for a pre-commit hook is to pass all the discovered filenames to the entry, and when yamlfmt receives references to exact files in its list of arguments, by design it will run them through the formatter without checking whether the config would want to run them. With the fix in v0.18.0, this would cause all files in a repo, including non-yaml ones, to run through the formatter unconditionally. I think I have finally settled on a proper implementation, which is explained in the docs.

On a related note, if you are knowledgeable about pre-commit and interested in the future of this project as a pre-commit hook, please take a look at my recent announcement: #​278

v0.18.0

Compare Source

The primary reason for this release is a change to the pre-commit hook that might be breaking to some users.

Features

pre-commit hook no longer specifies filetypes

The expectation for yamlfmt is to be run in a working directory of many different filetypes, and to configure what you as a user want the tool to run on based on configuration (file extensions, doublestar patterns, etc). The hook no longer specifies types: [yaml] like it used to. You can restore this behaviour by overriding it in your pre-commit config like so:

- repo: https://github.com/google/yamlfmt
  rev: v0.18.0
  hooks:
    - id: yamlfmt
      types: [yaml]

However, you will likely have a better experience by reconfiguring yamlfmt to match the intended experience.

Default usage message on misuse of command

If you use the command yamlfmt with no arguments, and no config is discovered, the tool will now output a default usage message to indicate to the user how to properly use the command.
