However, I’ve found that pure Ada code without a package manager is pretty easy to integrate using the gprbuild tool; you just copy the dependency’s .ads and .adb files into your project and add their enclosing folder to the list of source directories. gprbuild figures our how to build them pretty much automatically.
So I wish that instead of using TOML files, the dependencies would be specified in the gprbuild project files themselves. The syntax/options of GPR files would probably have to be extended, but it would be nice to have only one layer of config files that contains everything needed to build an Ada library/project.
There are several problems with GPR. The first is that it's GNAT-only and no other compiler would recognize it. The second is more technical: GPR is more "stringly-typed" than it ought to be, and thus despite a somewhat Ada-like syntax it isn't nearly as nice as Ada-source.
I've been mulling the idea of leveraging Ada's generic-system for a method to use as a Project specification/definition -- if you could have an Ada generic as a project-file, then you could [re]use the compiler/syntax-checker... I've also sketched out a way that Generic-parameters could be used by a project-builder program, generating an appropriate menu.
And with the GPR handling libraries and Libadalang there's already so much you can do...
Nice! Is there something similar for other languages?
PYPI kills me everytime I need to run any ML stuff, and I wish there was a systematic page to d/l all transitive dependencies (at least from requirements files and maybe setup.py static interpretation...)
Look for the metadata.json, in the dist-info directory
{
"requires": [
"chardet (>=3.0.2,<4)",
"idna (>=2.5,<3)",
"urllib3 (!=1.25.1,<1.26,!=1.25.0,>=1.21.1)",
"certifi (>=2017.4.17)"
]
}
You could also look at
pip download --no-binary ':all:' --src src requests
But if you want to actually proxy the individual download files, you'll need to iterate over the index files themselves, download them, and change their locations, which isn't overly difficult, but seems a bit beyond scope of a community index.
As I'm trying to upgrade our whole bash-monster GNAT+gnatcoll+lal+florist+gtkada+younameit to the latest GNAT PRO continuous delivery, I wish I could just let some better tool do this...
The example "Finding an Ada PDF library" is https://alire.ada.dev/search/?q=pdf. That leads to https://alire.ada.dev/crates/apdf.html, with

I like the use of tags to clarify which projects are in SPARK.
I realise it's in beta, but, some feedback: on the linked Crates page, there doesn't seem to be a way to browse the source of the projects. I was expecting to be able to click a link and be taken to something akin to a GitHub page, but this doesn't seem to be possible. Some of the crates link to project home pages.
Also, it would be neat if the Network graph page showed which projects were in SPARK, perhaps by using colour.

That's true, so far the contributors for crates have the option to provide a link to a website. This link can be to the repo, but it is not mandatory.

Good idea :)
