Can I SnoopPrecompile a Genie.jl app?

[TheLateKronos]

SnoopPrecompile can be used to precompile a set of function calls during package precompilation. As a Genie.jl app is a Julia project, I was wondering:

Is it possible to package a Genie.jl app as a package, and thereby use SnoopPrecompile.jl to make the app quick to launch? I am essentially looking for an autogenerated sysimage for the app.

In case it is not possible to package an app as a package, is there another way one could take advantage of SnoopPrecompile (or SnoopCompile) to get a similar outcome?

As long as you create it as a “package,” then you can use SnoopPrecompile.

Question about using SnoopPrecompile

One opportunity that probably most people are still not exploiting: with 1.8, the precompile work does not have to be in the package that “owns” the code. So what that means is that each user can construct a “personal Startup.jl” package and say using Startup at the beginning of a new session. So for example, if you like to use a combination of CSV, DataFrames, and StatsModels and want certain things to be fast, then you can Pkg.generate("Startup") in your dev folder and then the Startup package…

And that is my question exactly. It has a project.toml, and a manifest.toml, and is wrapped in a module. But I have not you seen the docs tell you to use Pkg to “add” it. So I am not sure if it possible, but I can not see what is missing. Is anything else needed to make it a “package”?

pkg> dev MyFavoritePrecompiledModule may be what you’re after. You can specify the whole path if it’s not in your .julia/dev folder.
