cli-help-maker 0.2.0

CLI help message generator.

cli-help-maker

Command Line Interface help message generator.

---

This repo contains a CLI to create simulated help messages with the positions annotated of the commands, arguments and options. Its created as a separated package, but its intended use is to generate datasets to be used in helpner-core, which deals with the model that powers helpner.

What range of help messages covers?

For the moment, it indents to recreate messages like those found in the examples of docopt-ng. This should cover CLI apps created in python using for example argparse, click or typer*.

typer uses click underneath, but when rich its is installed, the message has a special (and prettier) layout, currently not in the scope.

A proper list of items covered is yet to be made.

Installation

It can be installed directly from PyPI:

pip install cli-help-maker

This creates the following CLI:

❯ cli-help-maker --help
                                                                                                
 Usage: cli-help-maker [OPTIONS] INPUT_PATH [OUTPUT_PATH]                                       
                                                                                                
 Function to generate a dataset of cli help messages from a .yaml file with the info.           
 A folder will be generated containing two jsonl files:                                         
 - arguments.jsonl:     Contains the arguments that were generated, these can be associated to  
 each     help message for further analysis.                                                    
 - dataset.jsonl:     A dataset of help messages with annotations.

Examples

The folder examples contains a rough recreation of some of the examples found in docopt-ng repo, to see an example, run any of them, for example:

python examples/arguments_example_like.py

This would create a random help message with a layout similar to the one found in docopt-ng (approximately).

It highlights the labels using rich.

Development
