Tools should not advertise in your commit-messages.
So I created a pre-commit (well, commit-msg) hook for removing unwanted co-authored-by lines.

Them: Use LLMs

having written too many tree-sitter queries, ast-grep looks a lot friendlier for anything that isn't syntax-highlighting.

not much of it, I'm afraid. And no decompiler stuff as I did not have a license...
There's some struct-stuff in https://github.com/tmr232/Sark/blob/main/sark/structure.py that maybe relevant?
Truth be told, I didn't touch that code (or IDAPython, or IDA) in years...

Apparently, SVG is hard.
I guess I'll do hacky XML manipulation instead...

"Intel x86-64" does not automatically translate to "macOS" for me, making this a very confusing statement...

I tried un- and re-installing it. But I didn't delete all it's settings directories, so it changed nothing.
I'll probably test it on a different user on my PC, then do a deep clean and re-install if that works...
This just adds to my long list of frustrations with VSCode...

2025-08-29 18:11:43 UTC

I have an idea for a new VSCode extension, but I can't write it as it suddenly stopped letting me debug my extensions. No error messages, no warning, it just stopped loading them.
Honestly not sure what to do.

2025-03-09 17:06:46 UTC

I hardly ever read what I write. But writing helps me think things through.
Recording myself talk also has a similar effect.
I still find it weird that getting my thoughts out of my head adds so much value.

My concern is that since you key the dict using (name, param-count), duplicates will be dropped/overwritten

2025-01-26 15:42:05 UTC

- reply

Nothing popped out as "wrong" to me, except - can you have multiple functions with the same name?
That said, having `matcher`, `matched` and `matches` in the same piece of code is really confusing 🙃

Waiting for results once this happens... https://github.com/joxeankoret/diaphora/issues/159
But it might be a while, as 11.3 isn't out yet.

2025-01-13 10:46:32 UTC

Added the overlay-note-region-name-pending feature to the demo behind a feature-flag.
You can play with them at https://tmr232.github.io/function-graph-overview/?showRegions
Use `cfg-overlay-start: message` and `cfg-overlay-end` comments to denote the start and end of a region.

Currently working on adding comment-overlays to Function-Graph-Overview.
The idea is to add special begin- and end- comments, and use those to draw overlays on the graph (think C#'s region thingy).
I hope this will make the CFG more viable as a code-understanding tool, as we'll be able to better document our findings.

Returning to a piece of code a few months later is a great motivation to write documentation...

2025-01-09 11:56:13 UTC

I really hope I'm missing something, but I can't find a VSCode API that allows me, in an extension, to get an event when a breakpoint is hit.
Seems like a massive blocker for developing debugging tools.

New version of Function-Graph-Overview is out for both VSCode and JetBrains IDEs.
This version is a bugfix release, solving some edge-cases that led to infinite loops in rendering, and improving performance in some cases too. Thanks @npub17wv…nag2 for the fix!

Thinned the export down to this - https://gist.github.com/tmr232/09e4b1d5edf89a2c718a9d73aa6cec2f
This will still require some changes to the code to make this work, but should be rather straightforward once graphology imports the graph.

2025-01-01 17:43:27 UTC

- reply

I'll need to generate that...
Probably best if we do something that graphology can read (https://graphology.github.io/serialization.html#format) as it's the graph library I'm currently using.
I'll try to serialize graphs from my code to see which attributes are actually relevant and let you know.

2025-01-01 17:37:39 UTC

- reply

if we wanna style it the same, it's probably better to export a JSON of the nodes & edges (including edge types) so that we can use the same templates.
Then it's either we have the CI run Ghidra (probably not...), or we run it locally every now and then to generate a large collection of graphs, then post them gradually.

2025-01-01 14:57:00 UTC

as soon as I decide which server to put the bot on 🙃
As for Ghidra - that would be awesome! I always wanted to do that with IDA, but licensing made it tricky...

I can't seem to get WebView2 working in a Visual Studio extension, so I'm dropping that effort for now.
If anyone knows how to do this, or actually wants Function-Graph-Overview in Visual Studio, let me know!

do you know if Ghidra already generated Python type stubs?

2024-10-12 19:32:45 UTC

- reply

if GH did that, maybe. But in this case - it's just the JB task downloading 5GB of dependencies on every run. It took >5min to complete building on my machine.

2024-10-12 19:17:07 UTC

- reply

And also disabled gh-actions on the plugin-template repo. Just Dependabot jobs would probably eat up all my private free minutes...

2024-10-12 19:16:09 UTC

- reply

Yeah, most likely.
Also - something didn't work with the debug task, so instead of debugging I decided to try using their plugin to create a new plugin, instead of the template.
Naturally, it uses different versions of things, so I now have several GB's more of Gradle crap...
Honestly - if this is the JetBrains experience, I really can't complain about the NSA...

2024-10-12 19:03:56 UTC

Oh, wow, JVM dev is fun...
To build the JetBrains example plugin, Gradle downloaded multiple GBs of dependencies, and my ~/.gradle dir is not over 5GB.
In what world does this make sense???

Truth be told, I'm in awe of the mess that is the Ghidra build scripts.
I mean, I don't blame them. Most projects of that age would be as messy. But still, it's a pain.
I kinda wanna get the Kotlin Jupyter kernel working in Ghidra again, but I know it will be hell. So... Yeah, no.

2024-10-11 18:25:59 UTC

- reply

Yeah, Eclipse had literally decades to improve by now...
As for Ghidra development - why not use IDEA? It's been a few years since I did any of that, but I remember it working just fine for Ghidra plugins & scripts.

Eclipse, very non-native UIs that only kinda work, 90's OOP, and in my case - a Python tutorial I read as a kid that claimed Python is superior because it starts up slightly faster...

2024-10-08 13:03:35 UTC

I don't like the idea of only providing "dark mode", so I'm working on color-scheme support & creation.
Surely, that's the simple solution.

2024-09-06 12:46:50 UTC

I always wanted to have IDA's graph-overview for source-code.
So I created a small VS-Code extension to do that for me.
https://marketplace.visualstudio.com/items?itemName=tamir-bahar.function-graph-overview
It currently supports only Go code, but adding more languages should be relatively straightforward.
