Status

Almost everything is implemented, and a WIP version will be available soon.

TODO till first release:

• Add Content section to this README.
• Add a small example to the beginning of this README.
• Check the grammar in this README.
• Generate .html file from the tutorial part of this README and put it into doc directory.
• Write a rockspec for v0.1 and push it to moonrocks.

TODO till first 'stable' release:

• Write a formal reference.
• Write more tests. Some cases are still poorly covered.
• Add mutually exclusive groups(:mutex{option1, option2, ...}).
• Optionally(?): Add comments to the source.
• Optionally: get rid of 30log dependency. It's great but can cause problems with old luarocks versions.

Installation

Using luarocks

Installing argparse using luarocks is will be easy.

$ luarocks install argparse

Problems with old luarocks versions

You may get an error like Parse error processing dependency '30log >= 0.8' if you use luarocks 2.1 or older. In this case, either upgrade to at least luarocks 2.1.1 or install 30log manually, then download the rockspec for argparse, remove the line "30log >= 0.8" and run

$ luarocks install /path/to/argparse/rockspec

Without luarocks

Download /src/argparse.lua file and put it into the directory for libraries or your working directory. Install 30log using luarocks or manually download 30log.lua file from 30log repo.

Tutorial

The tutorial is available online and in the doc directory. If argparse was installed using luarocks 2.1.2 or later, it can be viewed using luarocks doc argparse command.

Testing

argparse comes with a testing suite located in spec directory. busted is required for testing, it can be installed using luarocks. Run the tests using busted spec command from the argparse folder.
