crabviz's Issues

Previewing exported svg

After exporting call graph, can we preview again with crabviz extension? Because other svg extensions i tried are not interactable.

panic while generating a call graph

there is a panic while generating a call graph:

Doesn't Identify Calls Through Actix Route

Neat extension, I went to test it on some stuff I had lying around and noticed that it didn't identify functions that were called as routes for Actix. I have a repo that I was using while working through Zero to Production in Rust that I used to test.

I found that when looking at the graph for the entire src folder, it shows that my functions for routes are never called:

When checking the call hierarchy in VS Code, it correctly shows that this health_check function is called by run, which is called by spawn_app and main:

Source is here for reference: https://github.com/Torsitano/zero-to-rust/blob/main/src/routes/health_check.rs

CrabViz not showing graph

I'm trying to run CrabViz, and I'm not getting a visualization. I do the following:

1. right-click a directory on the left hand nav
2. Click "CrabViz: generate call graph"

And nothing happens. CrabViz does briefly pop up with "loading languages" but that's about it.

I'm happy to debug, but not sure about how to do so. Are there instructions on how to do so?

I'm using VSCode with the SSH plugin, if that changes anything.

Only function names without directed segments

I have tried this plug-in several times with different java projects, and the generated results are only the functions in the project, and there is no calling relationship between functions, that is, directed line segments.I'm desperate to know what's causing this.

TypeError: WebAssembly.instantiate(): error: module is not an object or function

Error:

Compiled code:

I ran the extension in watch mode. In the new window I selected "Crabviz: Generate Call Graph" from the context menu.

Any build steps which went wrong? Can you please guide me through this?

Thanks for the help!!

how to save graph

failed to work well with clangd

C++, clangd, and when i clicked generate call graph, nothing happened.

Does not seem to work with Python3

Looks amazing! But, Does this work with Python3? I get "no matching workspace symbols" errors. I think these were due to my init.py files which I deleted. However, no image is opening in vscode. Any ideas on how to get it working? Would be much appreciated :)

询问

对项目很感兴趣，可否一起开发

Tree view

Cool use of the LSP! It would be much more useful to me if it was possible to display in a tree (-like) layout instead of blocks for each file.

Can't zoom in far enough

In a project at work, the call graph probably has several thousand items (we have et least 800 elixir modules).

When initially created the graph is just a thin vertical line, after maximally zooming in, it is a bold vertical line created from blocks, that seem to have labels. It is still not quite usable.

I have not yet been able to try this on smaller projects or comperably large projects in another language.

what vscode version need

For better experience for usage

When I click on an item, it becomes relevant only to that item.
But if I click on a blank space (or scroll the canvas), it becomes all relevant.

Here are some ideas:

• Lock
  If I can right-click or something .To make the canvas lock only one item,
• Change the canvas by double-clicking
  make clicking the blank canvas doesn't become all relevant.
  Or double-click directly to change the interface
• Or allow the keyboard to move the canvas to make mouse or touch is no need.

---

当我点击一项时,它变为只会这一项有关.
但如果我点空白的地方(或者拉动画布),就会变为全部相关.
我有一些想法:

• 锁定
  如果可以右键或别的方法,来让界面锁定只有一项,
• 变化界面通过双击
  暂时让点空白画布不会变为全部相关.或者直接双击才对界面有变化
• 或者支持键盘移动画布
• 而避免 要移动画布时, 鼠标或触摸对界面改变.

这可能是#9的一个复制

Feature request: Call graph with the current function

这插件简直梦中情插，只不过我之前用的是source insight，一直想要找一个类似下面这个repo 中的 visual studio 插件的效果：
https://github.com/league1991/CodeAtlasVsix
就那种点哪儿就跳哪儿那种。
当然，单纯用 call hierarchy 也行，可是就想看图。。只恨我自己太菜，啥rust啥都不懂，球球了，大佬让我白嫖下吧(狗头保命)

if a method in macro_rules, the method won't be included in the generated graph

source file: tokio/src/runtime/runtime.rs
expected result: function new will be in the generated graph
Actual result: function new is missing

Error in language detection

I want to show graphviz about cranelift, but found error as follow.

I don't know exactly why. Can you take a look for me?
