I want to convert my tiny tui code into a package, bundle it, and allow people to use it via the url package thing. It depends on the basics_cli platform.
My best guess was to create a tui.roc file in the dir I'm working in and put this in it
package "tui"
exposes [
Term,
Term.Unicode
]
packages { pf: "https://github.com/roc-lang/basic-cli/releases/download/0.2.0/8tCohJeXMBUnjo_zdMq0jSaqdYoCWJkWazBd4wa8cQU.tar.br" }
And then maybe run roc build tui.roc? Doesn't seem quite right, and that command also hangs.
Is there a script or process that I could check out on how to prepare the necessary .tar.br?
Bonus points, I would also love to generate docs for it :dancer:
Matthew Griffith (Mar 05 2023 at 13:45):Ahhh, just found roc build --bundle=.tar.br!
Matthew Griffith (Mar 05 2023 at 13:50):So, I think the issue is just that roc build tui.roc hangs.
Running with the --bundle produces this error
Maybe I need to create a directory or something? :thinking:
Richard Feldman (Mar 05 2023 at 14:51):definitely seems like a compiler bug! is there a link to the code I can use to reproduce?
Matthew Griffith (Mar 05 2023 at 15:25):Yes! Just made it public here: https://github.com/mdgriffith/roc-tui
Brendan Hansknecht (Mar 05 2023 at 15:51):Does term depend on basic_cli?
Brendan Hansknecht (Mar 05 2023 at 15:51):If so, i think that is the issue
Brendan Hansknecht (Mar 05 2023 at 15:51):I don't think a package can depend on a platform
Matthew Griffith (Mar 05 2023 at 16:46):Ah, interesting, ok
Matthew Griffith (Mar 05 2023 at 16:47):Is that a design constraint or something that hasn't been implemented yet?
Brendan Hansknecht (Mar 05 2023 at 16:49):Design constraint
Brendan Hansknecht (Mar 05 2023 at 16:49):I don't think there is any plan to change that, but I could have missed something.
Matthew Griffith (Mar 05 2023 at 16:55):Ok, good to know!
Brendan Hansknecht (Mar 05 2023 at 16:55):Packages can't directly depend on platforms. They need to depend on a shared type or use other abstractions to convert to the platform types and effects.
Brendan Hansknecht (Mar 05 2023 at 16:55):This keeps effects out of the packages.
Brendan Hansknecht (Mar 05 2023 at 16:56):Hmm....That said, given effects are changing and becoming pure tag unions, I guess that would enable packages to use them directly...hmmm
Brendan Hansknecht (Mar 05 2023 at 16:56):so yeah, things may change some.
Matthew Griffith (Mar 05 2023 at 16:57):Awesome :sunglasses: For now I can make it pure and have them pass in the Stdout stuff!
Brendan Hansknecht (Mar 05 2023 at 16:59):#ideas > effects in packages I think this discussed it some and fancier abstractions.
Richard Feldman (Mar 05 2023 at 19:24):yeah it should be possible in the future but it's not yet :big_smile:
Richard Feldman (Mar 05 2023 at 19:24):(packages depending on platforms I mean)
Richard Feldman (Mar 05 2023 at 19:25):once https://github.com/roc-lang/roc/pull/5093 lands we might be able to start converting platforms over to that representation though!
Brendan Hansknecht (Mar 05 2023 at 19:35):Oh, that's getting close. So exciting. Hopefully the rebasing for updating the glue stuff I have worked on isn't too painful.
Folkert de Vries (Mar 05 2023 at 19:55):it should not be too bad I think. mostly it just needs the glue gen for function types
