yamlfixer-opt-nc 0.3.4

automates the fixing of problems reported by yamllint

❔ About

yamlfixer automates the fixing of problems reported by yamllint by parsing its output.

📑 Prerequisites

💡 You can try the install process online thanks to the dedicated Katacoda scenario.

In order for it to work, yamlfixer needs that the following utilities are already installed on your system, in a directory present in your $PATH :

• Python v3.6 (or higher)
• yamllint v1.26.3 (or higher)

Then simply install yamlfixer from pypi

python3 -m pip install yamlfixer-opt-nc

🚀 Usage

This software automatically fixes some errors and warnings reported by yamllint.

usage: yamlfixer [-h] [-v] [-b] [-d] [-j | -c | -s] [file [file ...]]

Fix formatting problems in YAML documents. If no file is specified,
then reads input from `stdin`.

positional arguments:
  file                the YAML files to fix. Use `-` to read from `stdin`.

optional arguments:
  -h, --help          show this help message and exit
  -v, --version       display this program's version number and exit.
  -b, --backup        make a backup copy of original files as `.orig`
  -d, --debug         output debug information to stderr.
  -j, --jsonsummary   output JSON summary to stderr.
  -c, --colorsummary  output colored plain text summary to stderr. If stderr
                      is not a TTY output is identical to --summary.
  -s, --summary       output plain text summary to stderr.

yamlfixer launches yamllint on each specified filename, then parses its output and try to fix the reported problems. The special filename - means stdin, and is assumed if there's no other filename argument.

If input is read from stdin, the corrected output will be sent to stdout.

Other files will be overwritten if needed. Original files, stdin excepted, can be preserved as .orig if the --backup command line option is used.

Both summaries and diagnostic information are sent to stderr.

This command exits with -2 if yamllint is not available on your system. Otherwise it exits with 0 if all input files either are skipped or successfully pass yamllint strict mode, else -1.

IMPORTANT: Not all problems are fixable by yamlfixer. Due to the fact that yamllint doesn't currently report all faulty lines, yamlfixer might even introduce indentation problems under some circumstances.

⚠️Use at your own risk, you have been warned... ⚠️

💪 Tips and tips

⏩ One liners

Most of use love short and efficient command lines. Here are some ready to use ones :

Piping json summary through jq

yamlfixer --jsonsummary bad.yml 2>&1 | jq

So you can get a nicely colored (and vlidated json output) :

  "filestofix": 1,
  "passedstrictmode": 1,
  "modified": 0,
  "skipped": 0,
  "notwriteable": 0,
  "unknown": 0,
  "details": {
    "/home/jerome/yamlfixer/bad.yml": {
      "status": "PASSED",
      "issues": 0,
      "handled": 0
    }
  }
}

Check if yamlfixer could fix a yaml and get the exit code

See how piping fixing and linting can be intersting... and get exit code so you can go furher in automation :

yamlfixer <bad.yml | yamllint --format parsable --strict -
echo $?
