#debugging

5 posts4 participants0 posts today

Got up and running with debugging Go code in Emacs in about 2 minutes.

It renders variables inline, as well as when I put my cursor on a variable (eldoc-box).

dape lets me navigate the call stack, it auto expands all local variables, it provides a REPL and more besides.

And all I did was:

# pacman -S delve
M-x dape RET RET

I've yet to try out the more advanced features of delve, like attaching to a running process, but first impressions sure look good!

🎙️ Time for another episode of the core․py podcast!

🕹️ Are we finally covering the long-awaited topic of garbage collection? Well, no. Pablo wanted to talk about his latest PEP 768 instead. And it's indeed an interesting deep dive into how debuggers work.

🖍️ We also argue about syntax highlighting in PyREPL and resolve the bet around reference counting from Episode 18!

We also resolve the bet about reference counting semantics, mention some notable changes in Python since the last episode, and discuss syntax highlighting in PyREPL and why it's bad, actually.## Timestamps(00:00:00) INTRO(00:02:16) PART 1: PABLO'S LATEST PEP(00:04:34) gdb is IMPOSSIBLE(00:12:49) Make the process run code for you(00:14:14) This already works on PyPy(00:15:13) How does it work?(00:25:38) Why a file?(00:31:15) What if you don't trust Pablo?(00:32:57) sys.remote_exec()(00:36:09) Less obvious use cases(00:46:56) PART 2: BETS(00:55:44) PART 3: PR OF THE WEEK(00:55:50) Łukasz: syntax highlighting in PyREPL(01:10:14) Pablo's PR: allow the parser to activate future imports on the fly(01:20:11) PART 4: WHAT'S GOING ON IN CPYTHON(01:20:22) Free threading(01:23:30) Performance(01:34:41) PEP 765 implemented(01:36:08) concurrent.futures.Executor.map(buffersize=)(01:36:57) io.Reader and io.Writer(01:38:40) Pabluco's linecache fetching interactive source code(01:41:25) ast.unparse() roundtrip with semicolons(01:41:59) OUTRO
