[LFX] Enhancement: KCL IDE automatically updates the dependencies through kpm

[zong-zhe]

Enhancement

When a KCL package is loaded using KCL IDE, the IDE automatically updates the dependencies of the current KCL package through the kcl mod command.

Can I some more context here? @zong-zhe @Peefy

Hi @octonawish-akcodes 😄

Let me add more details to this issue.

KCL IDE is the main interface for users to write KCL, and kpm is the package management tool for KCL, used for managing KCL's third-party libraries.

KCL IDE is developed based on LSP - https://microsoft.github.io/language-server-protocol/
@He1pa 😊 can provide more details about KCL IDE.

KCL IDE uses kpm commands to manage KCL packages. The main work of this issue is to make KCL IDE automatically update the current KCL package's third-party dependencies according to the kcl.mod file in the KCL package when loading the KCL package, so that a legal KCL package will not cause errors cased by the third-party dependencies has not been updated.

The command used by kpm to update the KCL package's third-party library is kcl mod update, more details

• https://github.com/kcl-lang/cli/blob/d05b19dca5338fb8df5298cf61a5fa46b4854178/cmd/kcl/commands/mod_update.go#L38

Sorry that there is no document about `kcl mod update` on the official website https://kcl-lang.io/docs/tools/cli/package-management/command-reference/init, which is our negligence. We have raised an issue https://github.com/kcl-lang/kcl-lang.io/issues/253 to track this issue.

We previously integrated a command kcl mod metadata to help the IDE find KCL third-party libraries during the compilation process. kcl mod updatecan be integrated with KCL IDE in a similar way

• kcl/kclvm/driver/src/kpm_metadata.rs

  pub fn fetch_metadata(manifest_path: PathBuf) -> Result<Metadata> {

If any other questions, please let me know 😄 😄 😄

Just a small query, how can I test my code?

Hey @zong-zhe, i got over the explaination you've given and have doubts regarding my conclusion, please correct me if i am wrong. So the fetch_metadata() function just gives us the output that fetch_mod_metadata() function returns after it passes the command 'kcl mod metadata'... from this, we store those third-party dependencies and iterate over each and verify if they need to be upgraded or not.

I can try to figure this out on my own but can you please save my time by mentioning how do i check this "version of a third-party dependency".Thank you. 😊

[octonawish-akcodes]

I believe you can see the versions of those third party dependencies in kcl.mod file.

Hi @d4v1d03 😄
Good question ! 👍 Our design is that all functionalities related to package management are handled by kpm. The KCL IDE is only responsible for sending requests to kpm and obtaining the corresponding processing results. Therefore, the storage and validation of third-party dependencies is done in kpm.

kpm is here ! - https://github.com/kcl-lang/kpm

Hi @d4v1d03 , The Package Version Management is still in progress.
More details here: kcl-lang/kpm#246

[d4v1d03]

Ok @zong-zhe , thanks for the clarification. I will work on the pretest you mentioned over here. Are there any couple more to work on so i could get a good grasp of kpm.
