I’ve been trying out the Julia debugger in VSCode and found a few issues with it.
_Windows 11, VSCode 1.93.1, julia-vscode v1.123.2_
Are these all known issues? If not, where should I report them, the VScode plugin project, or Debugger?
**REPL Mode**
within REPL, `@run` only works once per session; otherwise it hangs and never hits the breakpoint.
**Run & Debug Mode**
Can’t change breakpoints while paused. Also, this breaks the ‘Run to Cursor’ feature.
Julia: Compiled Code mode worked initially, but stopped working as soon as I changed it. ‘Apply default’ appears to work, but did not restore functionality.
Debugger stopped working at one point and I needed to restart VSCode. Not sure how to repro this one, but I’ll try to identify repro steps.

What version of Julia? What is in your global Project.toml file? Do you have a piece code that can replicate this behavior in a fresh directory?
You can open issues on the Julia VSCode extension GitHub, but I think you’re more likely to get help here.

Julia 1.10.5
This is in a new project, only added `Revise`, `Infiltrator`
Another person encountered the only can `@run` once per session bug:
> [@Debug only running once in VSCode](https://discourse.julialang.org/t/debug-only-running-once-in-vscode/119881):
>
> When I use @run at the VSCode Julia REPL to start a debug session it works fine the first time it is called. But every subsequent time it just spins and the debug session never gets started. I have to kill the REPL and make a new terminal to get it to start again. This started happening a while ago. How can I fix it? If I ctrl-C the @run I get this stack trace: julia\> @run make\_function([f],[d]) ^C ERROR: InterruptException: Stacktrace: [1] try\_yieldto(undo::typeof(Base.ensure\_rescheduled)) …

I’ll try to give it a go tomorrow and see if I can figure anything out!

For me this happens in every project. I’ve got about 5 I regularly mess with all with very different dependencies. Here’s my startup.jl file, if that is helpful:
```julia
using Pkg
let
pkgs = ["BenchmarkTools", "OhMyREPL", "Revise", "Crayons"]
for pkg in pkgs
if Base.find_package(pkg) === nothing
Pkg.add(pkg)
end
end
end
using BenchmarkTools
using OhMyREPL
using Crayons
import OhMyREPL: Passes.SyntaxHighlighter
try
using Revise
catch e
@warn "Error initializing Revise" exception = (e, catch_backtrace())
end
function vscode_color_scheme()
scheme = SyntaxHighlighter.ColorScheme()
# colors to match VSCode dark color scheme
SyntaxHighlighter.string!(scheme, crayon"ce9178")
SyntaxHighlighter.comment!(scheme, crayon"6A9955")
SyntaxHighlighter.function_def!(scheme, crayon"DCDCAA")
SyntaxHighlighter.call!(scheme, crayon"DCDCAA")
SyntaxHighlighter.macro!(scheme, crayon"DCDCAA")
SyntaxHighlighter.error!(scheme, crayon"F44747")
SyntaxHighlighter.number!(scheme, crayon"B5CEA8")
SyntaxHighlighter.op!(scheme, crayon"d4d4d4")
SyntaxHighlighter.keyword!(scheme, crayon"569cd6")
SyntaxHighlighter.symbol!(scheme, crayon"4EC9B0")
SyntaxHighlighter.argdef!(scheme, crayon"4EC9B0")
return scheme
end
SyntaxHighlighter.add!("VSCode", vscode_color_scheme())
colorscheme!("VSCode")
ENV["JULIA_EDITOR"] = "code.cmd"
```
I also created a new empty project with just one file and no dependencies. Here’s the contents of the file:
```julia
module Garb
greet() = print("Hello World!")
export greet
end # module Garb
```
and here are the dependencies:
```julia
(Garb) pkg> st
Project Garb v0.1.0
Status `C:\Users\seatt\OneDrive\Documents\temp\Garb\Project.toml` (empty project)
```
Here’s the result of doing `@run greet()` twice:
```julia
julia> using Garb
julia> @run greet()
Hello World!
julia> @run greet() #debugger goes into infinite wait loop here
```

Yes, unfortunately a recurrent issue. But it’s probably not a direct fault of the Julia extension. At least things did not change when I went back to versions that I know were working before.

Could this issue be caused by recent updates to Visual Studio Code? It’s not isolated to Windows, so it might be a more general problem: [Debugger runs fine once. When I use it again, it seems to be stuck in a loop · Issue #3688 · julia-vscode/julia-vscode · GitHub](https://github.com/julia-vscode/julia-vscode/issues/3688)
