NOTE: This repository has been moved to git.sr.ht/~ma3ke/phrace.
A terminal viewer for .xvg files.
Gromacs tools can output xvg files to inspect a range of properties of molecular dynamics trajectories (e.g. gmx energy).
These data files are commonly viewed with the Grace (xmgrace) tool.1
If you don't have Rust installed on your system, learn how to do it here. It is very easy.
To install the binary, run the following command.
cargo install phraceSimply invoke with a path to an xvg file. The size of the plot will be inferred from the terminal size.

You can specify the width and/or height explicitly as well.

Rendering the plot with an ASCII style is also possible.

If I have some time, I want to add more options to change the viewport, add axis tick labels, ability to plot multiple columns at once. For now, it fits my needs, and I am putting it out there for others to use in case they find it useful in its current state.
I am interested in adding support for more data formats. Honestly, it would be pretty cool to add the ability to graph out some weird and esoteric formats, but maybe doing like... csv is cool too I guess. Get in touch if you have a particular need, and we can see whether we can pull some programming crimes together.
More plotting styles may also pop up if I feel inspired.
In other words: contributions and collaboration welcome.
Depends on the terminal_size crate for getting the width and height of the terminal.
Depends on the lexopt crate for parsing command line arguments.
No other dependencies.
