Hi all,

Does someone know whether there is a way to show what functions are already precompiled in the current REPL session?

I think such function could be useful to create

1. a REPL instance manager (htop for Julia)
2. in conjunction with [PackageCompiler](https://github.com/JuliaLang/PackageCompiler.jl)
3. Along the lines of other inspectability tools like `bitstring, @which, @edit` and the like.

If someone can show me a direction to look I might try my hand at implementing something similar. Is PackageCompiler.jl a good place to start looking?

kr,  
Dieter

This gets all the inferred instances:

```julia
using MethodAnalysis
methodinstances()

```

It’s a tiny bit more laborious (see the MethodAnalysis docs), but you can scan for CodeInstances if you want compiled code.
