Make cmark-gfm as dependency package

[nbmisen]

My project uses github.com/apple/swift-markdown's SPM as a dependency, and swift-markdown uses https://github.com/apple/swift-cmark as a dependency. When I also use swift-markdown-ui as a dependency, Xcode indicates a conflict with cmark-gfm. Therefore, is it possible to use cmark-gfm as a dependency rather than as source in the code?

Conflict report：multiple targets named 'cmark-gfm' in: 'swift-cmark', 'swift-markdown-ui'

I have the same issue. What's the recommendation?

Same issue. Is this repository still active ?

Hey folks,
Sorry for the late response. Unfortunately, apple/swift-cmark is not using semantic versioning, so is not possible make a flexible version requirement.

For instance, this doesn't work:

dependencies: [
  .package(url: "https://github.com/apple/swift-cmark", "swift-4.2-RELEASE"..<"swift-5.10-RELEASE")
]

Additionally, apple/swift-markdown depends on the gfm branch, instead of an specific version:

https://github.com/apple/swift-markdown/blob/907674c2ae2d24c32fba50101821b1a7fdd291e2/Package.swift#L48

I will be happy to use apple/swift-cmark if it were possible to have a flexible requirement on the version. I am open to any ideas.

Thanks!

Hey everyone, I had the same issue a few months ago and created a fork which uses apple/swift-markdown. Initially I've planned to open a PR here but since I had limited time and needed to remove a few methods from the public API (might be due to lack of knowledge), I've restrained from doing so.
Maybe it is of some help to anyone.
If this is interesting to you @gonzalezreal, I can open a PR.
Here's the branch: https://github.com/lovetodream/swift-markdown-ui/tree/feature/swift-markdown-refactor

Having the same issue. Has there been a solution for this yet?

I ended up using @lovetodream branch which WFM.

@gonzalezreal swiftlang/swift-cmark has added semver tags (0.5.0 for example)

[gonzalezreal]

@wesleymccloy Good to know! I will give it a try.

[gonzalezreal]

You can try it here:

• Replace embedded cmark-gfm by swift-cmark #348

I would like to have some feedback before merging that PR. Please react with thumbs up if it works for you. Otherwise, let me know in the comments.

Hi @gonzalezreal I have noticed this warning in Xcode otherwise no issues:

[gonzalezreal]

Hi @hyperlink,

You are probably getting that warning because your project is still pointing to apple/swift-markdown, instead of swiftlang/swift-markdown. Apple moved a bunch of open source projects from apple to the new swiftlang organization.

I created a new project and added swiftlang’s swift-markdown. However, I’m still seeing the warning.

The warning should be gone in the main branch, but the 0.5.0 tag still references Apple’s swift-markdown.

https://github.com/swiftlang/swift-markdown/blob/8f79cb175981458a0a27e76cb42fee8e17b1a993/Package.swift#L49

[gonzalezreal]

Yep, that could be the issue. So, the workaround is to use the main branch for swiftlang/swift-markdown until there is a new tag that uses the proper organization name for swift-cmark. There is nothing we can do on our side.
