Flameshow seems better than tfg

Thanks for the tip, haven't seen it before!

Though there are some issues with it:

• distribution (pyinstaller cannot handle it, but PyOxidizer could) - done
• size (instead of 8MiB for tfg it requires 25MiB at least stripped and compressed, but suppose this OK)
• ensure that the input format is correct - Fix parser in case of symbol contains number with a space laixintao/flameshow#67
• there are some terminal manipulation overlaps between chdig and flameshow - 8c265c9

Once I will fix this, tfg could be replaced.

But long term goal is to rewrite it to Rust.

Perfect!

Btw, it seems PyOxidizer allows embedding python code into rust. And it explicitly serves as a python-to-rust helper, which meets the long term goal :

While solving packaging and distribution problems is the primary goal of PyOxidizer, a side-effect of solving that problem with Rust is that PyOxidizer can serve as a bridge between these two languages. PyOxidizer can be used to easily add a Python interpreter to any Rust project. But the opposite is also true: PyOxidizer can also be used to add Rust to Python. Using PyOxidizer, you could bootstrap a new Rust project which contains an embedded version of Python and your application. Initially, your project is a few lines of Rust that instantiates a Python interpreter and runs Python code. Over time, functionality could be (re)written in Rust and your previously Python-only project could leverage Rust and its diverse ecosystem. Since PyOxidizer abstracts the Python interpreter away, this could all be invisible to end-users: you could rewrite an application from Python to Rust and people may not even know because they never see a libpython, .py files, etc.

Indeed!
I already added this into my todo list

P.S. maybe I should convert my todo list into issues on github...

It is not that transparent, but looks like it works more or less OK - ccfa72d (#6)
