Formatter for Gherkin language
Table of Contents
Reformat-gherkin automatically formats Gherkin files. It ensures a consistent look regardless of who wrote the file.
It can be used either as a command-line tool, or a pre-commit hook.
Install reformat-gherkin using pip.
pip install reformat-gherkin
It requires Python 3.7+ to run.
To get started straight away:
You should get good results without specifying any options, as reformat-gherkin uses sensible defaults.
You can list the available options by running
Usage: reformat-gherkin [OPTIONS] [SRC]... Reformat the given Gherkin files and all files in the given directories recursively. Options: --check Don't write the files back, just return the status. Return code 0 means nothing would change. Return code 1 means some files would be reformatted. Return code 123 means there was an internal error. -a, --alignment [left|right] Specify the alignment of step keywords (Given, When, Then,...). If specified, all statements after step keywords are left- aligned, spaces are inserted before/after the keywords to right/left align them. By default, step keywords are left-aligned, and there is a single space between the step keyword and the statement. -n, --newline [LF|CRLF] Specify the line separators when formatting files inplace. If not specified, line separators are preserved. --fast / --safe If --fast given, skip the sanity checks of file contents. [default: --safe] --single-line-tags / --multi-line-tags If --single-line-tags given, output consecutive tags on one line. If --multi- line-tags given, output one tag per line. [default: --single-line-tags] --tab-width INTEGER Specify the number of spaces per indentation-level. [default: 2] --use-tabs Indent lines with tabs instead of spaces. --config FILE Read configuration from FILE. --version Show the version and exit. --help Show this message and exit.
Reformat-gherkin is a well-behaved Unix-style command-line tool:
- it does nothing if no sources are passed to it;
- it only outputs messages to users on standard error;
- it exits with code 0 unless an internal error occurred (or --check was used).
Reformat-gherkin can read project-specific default values for its command line
options from a
reformat-gherkin looks for the config file starting from the
common base directory of all files and directories passed on the command line.
If it's not there, it looks in parent directories. It stops looking when it
finds the file, or a .git directory, or a .hg directory, or the root of the file
system, whichever comes first.
Example config file:
check: False alignment: left tab_width: 4
Version control integration
You can integrate reformat-gherkin into your version control workflow by using
pre-commit. Once you have installed pre-commit, add
this to the
.pre-commit-config.yaml file in your repository:
repos: - repo: https://github.com/ducminh-phan/reformat-gherkin rev: stable hooks: - id: reformat-gherkin
pre-commit install and you're ready to go.
This project is inspired by black. Some
functions are taken from
