Sometimes, before I publish a new version of the package I accidentally forget that I’ve added a package to the dependencies and forgot to add [compat] entries in `Project.toml`.

I think I should add a git hook to remind me, but I wanted to check if there’s a simple function that I can use to check for missing [compat] vs [deps].

I’m not familiar with its API (so I can’t point you directly to the function you want), but that’s what [`RegistryCI.jl`](https://github.com/JuliaRegistries/RegistryCI.jl) does.

I think that Aqua.jl offers this as one of its features.

I guess you rather want something that can be automated but for interactive use, [PackageCompatUI](https://discourse.julialang.org/t/ann-packagecompatui/58118) will clearly show if you’re missing some compat and let you quickly correct it.

If your package is already pushed to GitHub and you have setup [CompatHelper.jl](https://github.com/JuliaRegistries/CompatHelper.jl) with `workflow_dispatch:`, then you can also trigger a CompatHelper run in the GitHub Actions tab to detect missing compat entries.

PkgTemplates.jl sets the GitHub Action for CompatHelper.jl even up as default.

Checking `[compat]` entries without depending on anything else is literally **the** function of the [CompatHelperLocal.jl](https://juliahub.com/ui/Packages/CompatHelperLocal/x5A3V) package _[disclaimer: I’m the author]_.  
Doesn’t require uploading your package to github or registering it anywhere, just run

```julia
import CompatHelperLocal as CHL
CHL.@check()

```

and get the updated `[compat]` content if it’s incomplete or outdated. I find it most convenient to append this piece of code to `runtests.jl`.
