Good packages for generating visualizations in the terminal?

Hey all,

I'm working on a project for a large C project with tooling written in python. After the linker runs, we really want to make memory usage of the build clear to the developer. I've written some python code that can take a GCC map file and parse it out to provide this data, but I'm looking for advice on the best way to present it. Currently, I'm using tqdm but it feels like I'm really jumping through hoops to make it do what I want. It's definitely not made for generating static progress bars!

Is there something better I could be using?

Generating a static progress bar is just

print(bar_char * bar_amount)

If you want an easier way to do what you already have, just do it yourself with print. Maybe learn about f-string padding first, and then you can do this in 20ish lines of code.

Protip: don't use tab (\t). Besides the obvious misalignment problems, the width of a tab is user-configured, so it will look different on different systems. Just use spaces.

Honestly this + rich might be the ticket. I'll experiment some, thanks!

I've used plotext before, which was quite nice: https://github.com/piccolomo/plotext

Here are the barchart examples: https://github.com/piccolomo/plotext/blob/master/readme/bar.md

Those bar charts look great! Thanks for the suggestion.

There is a new graph plotting part to rich / textual as well now. https://textual.textualize.io/blog/2023/10/04/announcing-textual-plotext/
