Topic: packages pf

Hi, I'm a bit confused about what I should write for the packages pf

packages { pf: ??? }

Brendan Hansknecht (Dec 07 2023 at 16:09):

If you are new to roc, I would advise starting with the tutorial and using basic-cli.

In general, roc is always built on top of a platform. More details on platforms here: https://www.roc-lang.org/platforms

Brendan Hansknecht (Dec 07 2023 at 16:09):

please ask more questions if that isn't what you are looking for

Curious how people feel about pf in general. I think it trips me up a bit every time I read it because "platform" is a single word so it feels weird to have a syllable level abbreviation. For basic-cli I like packages { cli: "..." }, but I realize that might not feel natural for all platforms.

Brendan Hansknecht (Dec 07 2023 at 18:17):

When I saw you use cli I immediately wanted to change all of my code to use it as well. Reads so much nicer (though does kinda hide which package is the platform)

Slazaa (Dec 07 2023 at 18:18):

Oh I thought the field needed to be called pf

I agree. Also, the new app header I'll soon be working on will have a special platform keyword indicating which package is the platform:

app [main]
    requires {
        cli: platform "https://…/basic-cli/…",
        json: "https://.../roc-json"
    }

So it should be clear even if you use a different name.

Oh, so I don't need to finish my sentence. I've written so far that: "Is there a way to disambiguate between a purly Roc package and a platform? I know there is no package manager right now, but is the syntax planned to be the same? Because ..."

Richard Feldman (Dec 07 2023 at 18:31):

oh that's cool, I never thought of cli!

Richard Feldman (Dec 07 2023 at 18:31):

what would it be for basic-webserver? web? :thinking:

Richard Feldman (Dec 07 2023 at 18:32):

server?

Slazaa (Dec 07 2023 at 18:32):

wserv ?

Richard Feldman (Dec 07 2023 at 18:41):

so imports [cli.File.{ readUtf8 }] feels reasonable, although imports [web.File.{ readUtf8 }] feels weird :big_smile:

Richard Feldman (Dec 07 2023 at 18:42):

imports [server.File.{ readUtf8 }] feels more reasonable

Agus Zubiaga (Dec 07 2023 at 18:43):

web sounds like it would run on the browser

Elias Mulhall (Dec 07 2023 at 18:44):

If you're using Nea it could be nea :shrug:

This might partially depend on if the Roc community goes hard on the Elm philosophy that everything should have a very direct name, or if there are platforms with cute/colorful names.

Like in elixir Phoenix is a namespace for all code related to the web server. In context that's fine.

I think in the context of platforms it's natural to have a variety of names because the main point of platforms is to provide a way to build applications for a particular use case in a particular way, and there will naturally be different approaches with different tradeoffs for the same (or similar) domains

Richard Feldman (Dec 07 2023 at 18:49):

and nea is a great example of that!
