Project Proposal: More Interactive CLIs

[areebbeigh]

Currently, all the coala CLI interactions occur through numeric inputs which is very slow and cumbersome in most cases. This can be improved greatly by building more interactive CLIs using tools like PyInquirer. We have a lot of areas where the CLI can be improved.

For example we can use:

• the checkbox question type for coala-quickstart.
• the checkbox question type again when we run coala.

Apart from replacing number based inputs, we can:

• add auto-complete in prompting for bears in both coala and coala-quickstart.
• add a fuzzy finder like in git when we enter an invalid option to the CLI.

This could be a GSoC size project once all the potential areas of implementation are identified.

Note: If you're not familiar with using such CLIs, checkout:

• npm/yarn
• eslint CLI - eslint --init

This project is interesting and can be really helpful. @areebbeigh just an idea, $ 'coala --show-bears --filter-by language' command shows a list of bears that the user can use. While most bear names are self explanatory but for the others we can use something like Expand to provide their documentation. In this process we'll have to improve the documentation of some bears too.
