Add `--file` option to jlpkg?

[johnnychen94]

Hi,

I'm asking this because I'm writing some CI script in which I need to add a bunch of Julia packages to its base project (v1.1 in my case).

Instead of hard-coding the dependent package names in .travis.yml or .gitlab-ci.yml, I want to hold them in either a Project.toml or requirements.txt file.

The usage in my mind is:

jlpkg --project=path --file=Project.toml
# or
jlpkg --project=path --file=requirements.txt

I prefer the pip way requirements_julia.txt since Project.toml can be ambiguous when Julia is just one tool used in the whole project.

How do you think?

since Project.toml can be ambiguous when Julia is just one tool used in the whole project.

Why not use JuliaProject.toml then? I am a bit reluctant to add features here that does not exist in Pkg itself.

Alternatively you could just use requirements.txt (why is that not ambiguous though?) and execute

$ jlpkg add $(cat requirements.txt)

I'd like to explain the ambiguity I said:

We add items to Project.toml(not other names like JuliaProject.toml) mostly by Julia. If it's all about julia, then Project.toml is more convenient and explicit than requirements.txt.

When julia is only a part of the whole project, it's not so good to still use Project.toml, and if we need to support jlpkg --project=path --file=JuliaProject.toml, there's a copy&paste step between Project.toml and JuliaProject.toml. On the other side, julia_requirements.txt doesn't need this step.

I think jlpkg add $(cat requirements.txt) does most of my expectation, I'll check it, thanks.

I mean, Pkg already supports JuliaProject.toml.

Good to know that!

I'm closing it now since I don't have any further questions.
