Run yq across git branches!

QYT lets you run yq across git branches!

  qyt [options] <yq_expression> <file_regexp>

See yq docs for query syntax.

Examples

Read the name value from every yaml file

  qyt query '.name' '*.yml'

Display the top level keys for each file on each branch

  qyt query '{"b": $branch, "fp": $filename, "keys": keys}' '*.yml'

Committing Query Results

You can update files in each branch by configuring a commit message. qyu writes the result of the query to the source file and adds all the modified files to a commit.

The commit message is executed as a template with a populated "CommitMessageData" data structure.

  type CommitMessageData struct {
    Branch string
    Query  string
  }

For example when you run the following command (with branches main, and rel/2.0)

  qyt apply -m 'run {{printf "%q" .Query}} on {{.Branch}}' 'del(.name)' data.yml

The commit messages will look like

  run "del(.name)" on main

and

  run "del(.name)" on rel/2.0

See text/templates for template syntax.
