load_code unintentionally public? #335

What do you mean exactly by "code-only version"?
What do you mean exactly by "code-only version"?
For my particular case, a package namespace that includes only the functional API defined in the
R/folder, exclusive of the package data. I understand some of that API might not work (e.g. because it depends on data having been generated) and that features like documentation might not be available.That seems to be what the pkgload documentation suggests in https://pkgload.r-lib.org/reference/load_code.html: "Sources all .R/.r files in the R/ directory, storing results into the package namespace."
@pearsonca Gotcha! Please let me know if the latest main fixes your issue
@lionel- I can confirm it does, thanks.
Some further notes re ergonomics for my use case:
- to get at the functions, i have to use
packageName:::function(i.e. internal function) syntax - can't use the global context or::. I tried using attach(getNamespace(packageName), ...), which seems like it would have worked if I didn't have compiled code as well; to use that approach, I had to do load_code => load_dll. I opted for the:::mildly odd syntax since I didn't actually need any of the compiled code. - I have some data.table calls inside my particular functions. library'ing in data.table within the data-raw script was insufficient, had to use
.datatable.awaremarker in package. More generally, I expect there may be weird dependency problems for other packages with functions created by load_code
Not suggesting these need fixing, but might be worth updating function documentation to set expectations for direct use.

I'm attempting to use pkgload in a boot-strappy context with data-raw - basically, I want to use part of the R API while building the data.
I may be misreading, but
load_alldoesn't seem to support a code-only version. Hence, I went toload_code, which suggests it loads only the code.However, when I attempt to use
load_code()directly:(here testtesttest is the pure skeleton package from Rstudio -> Create Project -> Create R package)
The culprit seems to be in
ns_env- requires that a namespace already be loaded.So a few thoughts:
load_codenot intended to be public API pkgload?load_codeis supposed to be public API, clearly I'm using it wrong - is there a way to clear up how to use it properly in the documentation?
