pt_ref

Explore the public transport referencial with a nice DSL.

This project is a little funny POC, but nothing really polished.

Tutorial

First, you need a NTFS dataset. You can find NTFS dataset at the navitia open databar. If you are in a hurry, get the Île-de-France dataset (click on ntfs.zip)

Unzip your dataset.

You need a rust nightly toolchain.

$ curl https://sh.rustup.rs -sSf | sh
$ rustup toolchain install nightly

Now, download and build pt_ref

$ git clone https://github.com/TeXitoi/pt_ref.git
$ cd pt_ref
$ cargo +nightly build --release

And now you can play with it. I like to use rlwrap but that's optional. I also redirect stdout to a file to not spam the terminal (with a tail -f on the file on another terminal).

$ rlwrap ./target/release/pt_ref ~/dev/run/navitia/data/fr-idf/ntfs/ > /tmp/pt_ref.log

On /tmp/pt_ref.log, you'll have the json of your queries.
