Overview

MVG Fahrinfo

MVG Fahrinfo is a CLI tool to keep up-to-date with latest departure times of Munich public transport. The app is a native binary and uses official (albeit unpublished) MVG API.

It is made with Rust. 🦀

It features:

Very low resource usage.
Beautiful terminal interface.
Automatic refreshing of departures.
Searching of stations.
Saving stations to file.
Real-life colors for vehicles for easier identification.
Easy navigation with shortcuts.

Using

Clone the repository and run cargo run in the root directory. In the first run, it will fetch the stations list from the server and save it to stations.json file.

To force update the stations list file, just delete the file and run the app again. The app will stay open in your terminal and will refresh the departures every 60 seconds.

To exit the app, press q or Ctrl+C.

To run it globally, you can install the app with cargo binstall mvgfahrinfo. Make sure you have binstall binstall repo installed. Once installed, you can invoke the app just by running mvgfahrinfo in the terminal. This is a binary crate and not a library, so you shouldn't use it as a dependency.

I might provide some pre-built binaries for Windows/MacOS/Linux in the future. :)

Shortcuts

Normal mode

tab - Switch between departures and stations list.
r - Refresh departures.
s - Search for a station.
Up/Down - Navigate through the list of stations.
Enter - Select a station.
q - Quit the app.
Ctrl+C - Quit the app.

Search mode

Esc - Exit search mode.
Up/Down - Navigate through the list of stations.
Enter - Select a station.

Limitations

Currently, the app only handles ASCII or 1 byte UTF-8 character input. If you are searching a station with non-ascii characters (i.e. ö,ß etc.) in its name, the app will ignore the input. Please type the closest characters & scroll a bit down to select the station from the list (this will be fixed at a later version.)

Comments

Can not enter the char 'c' in the searchbar

When searching for a station the character c is not accepted as input.

For example: Searching for Candidplatz results in only the string andidplatz getting displayed in the searchbox

For stations like Candidplatz this is not an issue since the station will be found either way. However this is problematic for stations like Hackerbrücke which result in the search string Hakerbrüke which is obviously not yielding any results.

tokio-runtime-worker panicking
Hi there, Thanks for providing such a nice tool. I know close to nothing about Rust so this might be a very naive question/issue. The app works perfectly fine but whenever I close it I see the following message:

[~] mvgfahrinfo fetching stations... thread 'tokio-runtime-worker' panicked at 'failed to send tick event: SendError { .. }', /home/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/mvgfahrinfo-1.1.0/src/event.rs:50:50 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Did I do something wrong when installing it using binstall? Cheers

Question regarding mvg api

Hi, not an issue but more of question/ suggestion.

Where did you find mvg api endpoints? I did not manage to find it ob their website, also would is be possible to add a tracker to certain line, for example to see if there are issues with S2 or U2.

Migrate to tokio unbounded channel from std mpsc and other bug fixes
This converts the use of std::sync::mpsc to tokio::sync::mpsc for unbounded channel communication.

This also handles the negative departure time shown in some stations.

Handles non-ascii chars (UTF-8 size > 1 byte) by just ignoring them 😛

silghtly more greyish highlight color in station list tab

cleanup and other bug fixes.

Removing c/q char callbacks in search

This addresses the issue opened here: https://github.com/FaisalBinAhmed/MVGFahrinfo/issues/4

Now the characters c and q will only work as char input instead of special keys

To-dos for next version
[ ] default station on launch / user choice

[x] handle negative minutes

[x] handle non-ascii characters

[ ] fullscreen flag - departures take whole screen

[ ] redraw if frame resizes

[ ] handle code to-dos

[x] main loop getting stuck in some stations (due to bad data/parsing. ie. hbf) possible bounded std::mpsc issue

Thread panic after entering any character after Umlaut

Trying to enter any character after typing any Umlaut (ä, ö, ü), as in e.g. "München", crashes the app. Inserting umlauts in-between already typed characters seems to work, but it does weird things with the cursor position (it can be moved further to the right than the word should actually allow).
