Prerequisites for Scripts

There are some scripts in this repository with these prerequisites:

• git
• janet

Assuming those things are in place, clone this repository:

git clone https://github.com/sogaiu/ts-questions

The scripts that involve generating statistics across multiple repositories assume that parser / grammar repositories have been fetched to live under a repos subdirectory.

The repos directory can be populated by running the following script from this project's root directory:

janet ./script/fetch-repositories.janet

The list of repositories to fetch is determined via the file ts-grammar-repositories.txt.

Repositories within repos can be updated by using the following invocation in a manner analogous to the fetching one:

janet ./script/update-repositories.janet

This might be useful if one was interested in up-to-date statistics.
