.crab file extension

[TCROC]

I very much like @nonetrix 's proposal over here for the .crab file extension: #18 (comment)

Why?

1. It allows users to show their support for CrabLang on their GitHub repos!
   

2. Its cool 🦀😎

How?

I think we can make this work and still be compatible with r*st. We would just need a crabgo command to do the conversion. Probably something like:

crabgo crabify: .rs -> .crab
crabgo rsify: .crab -> .rs

For extra credit we can add a command to configure git with pre-commit and other .gitattributes that properly convert and / or compare .rs and .crab making for a frictionless developer experience. Something like:

crabgo gitify

Edit: New proposed Commands per discord discussion here: https://discord.com/channels/1074804478651400303/1095989994033782814/1096842935049404447

crabgo convert rs-to-crab: .rs -> .crab
crabgo convert crab-to-rs: .crab -> .rs

With the following shorthands:

crabgo convert crab = crabgo convert rs-to-crab
crabgo convert rs = crabgo convert crab-to-rs

---

Edit:

Some common questions have been:

Will we still support .rs?

Answer: Yes

I intend for the tool to make developing with both .rs and .crab a frictionless experience. Meaning it will allow libraries written in both .crab and .rs to work together.

Will this be in main / master?

No. It will either be in an experimental branch or as a subcommand in a new repository. I personally think the subcommand in a new repository is the best way to start. Here's some documentation to reference until we get the crabgo docs up: https://doc.rust-lang.org/book/ch14-05-extending-cargo.html

Edit: My new favorite proposal is from @mrquantumoff here

What about making something like

crabgo convert rs crab

which would mean rs => crab
and

crabgo convert crab rs

crab => rs

I think this is the perfect approach. Its just the right amount of verbosity. It ready from left to right as "from -> to" as most programming languages (all that I've used) do.

I think it completely does away with the need for shorthands.

[TCROC]

I'm personally in support of the convert [from-to-target] with convert [target] shorthand. Its clear concise and explains what is happening in the command.

[trvswgnr]

are you proposing these changes be on the stable branch, or the experimental branch?

[TCROC]

Experimental. Maybe even as a subcommand:

https://doc.rust-lang.org/book/ch14-05-extending-cargo.html

[TCROC]

Which would mean a new repository under the CrabLang umbrella.

^ This is probably the easiest way to start.

[mjovanc]

This is an excellent proposal!

[explosion-mental]

why not support both extensions?

[TCROC]

why not support both extensions?

Are you suggesting supporting both .rs and .crab? If so, that is also what I propose! :) I don't ever want to stop supporting .rs. .crab would be an addition and we would make sure we have the tooling to easily convert between .rs and .crab.

[trvswgnr]

i've been working on adding support for .crab. i think it's a good first step for our experimental branch. progress has been a little slow, but i think i am almost done with it.

i propose crablang/wastebasket#11 ( .🦀)

[trvswgnr]

i opened a PR in the crabgo repo that changes .rs to .crab. i'd like to support both extensions—and we will—but it's a little bit more intensive to do that.

crablang/crabgo#1

[Cuteistfox]

-1

[Cuteistfox]

@trvswgnr why not .🦀#53 .🦀

[mrquantumoff]

What about making something like

crabgo convert rs crab

which would mean rs => crab
and

crabgo convert crab rs

crab => rs

[TCROC]

What about making something like

crabgo convert rs crab

which would mean rs => crab and

crabgo convert crab rs

crab => rs

I like this proposal. I think it might be my new favorite. Will update the issue with it

[rlidwka]

Keep .rs extension.

There is absolutely zero reason to invent new extension for a language that has the same syntax.

In case crab codebase significantly diverges from upstream (which I doubt very much, given current nature of the project), syntax can be disambiguated using editions in Cargo.toml (smth like edition=crab-2021 instead of current edition=2021).
