Nice!

#

Is this not on the registry?

#

I think there needs to be a way to run this from scratch. If I understand correctly, rustup has a bootstrapping curl line that will get it started.

Yeah, it's assigned to rustup-init.sh.

The current status for ldcup is similar (in concept) to zigup by John Marler.

I was even reading dlang's official install.sh script and added something like that to generate the activation scripts.

# on linux (my host) test
➜  ldcup git:(main) ./bin/ldcup list --install-dir=$HOME/.ldc
["ldc2-6158df28", "ldc2-1.40.0"]
➜  ~ cd $HOME
➜  ~ ls .ldc/ldc2-1.40.0/           
activation  ldc2-1.40.0-linux-x86_64
➜  ~ ls .ldc/ldc2-1.40.0/activation/   
activate.bat  activate.fish  activate.sh
➜  ~ cat .ldc/ldc2-1.40.0/activation/activate.sh
#!/bin/bash
                export PATH="$PATH:/home/kassane/.ldc/ldc2-1.40.0/ldc2-1.40.0-linux-x86_64/bin"
                export DC_PATH=/home/kassane/.ldc/ldc2-1.40.0/ldc2-1.40.0-linux-x86_64
                %  
➜  ~ source $HOME/.ldc/ldc2-1.40.0/activation/activate.sh
➜  ~ ldc2 --version | head -n 3

Yeah, so I ran the install, and it doesn't tell me how to use it, so I couldn't find out how to call ldc2 or whatnot...

#

I still don't know where it is. the .ldc directory did not appear...

#

OK, I found it is in ~/.dlang. But the activate script doesn't override existing ldc2 path. I would recommend putting $PATH last, so it will replace any existing ldc2 you have in your path.

brazen knoll I still don't know where it is. the `.ldc` directory did not appear...

The .dlang directory appears because it is predefined, the custom-path does not. So when listing it you need to set the --install-dir=.ldc flag.

#

I was thinking about prefixing a directory through an environment variable to be listed or creating a configuration file showing the current directory.

Great idea! I had been uncertain about putting it in $PATH or $DC to set ldc2.

latest v1.0.9 minor bug fixes for cross-tarballs

OK, tried this again, and it seems to be working! A couple things: .bashrc did not work because I use .bash_profile. Also, I like the activation system that the dlang install.sh script does. Any chance you can clone that thing? Basically, you do . ~/.dlang/ldc-1.40.0/activate and it edits your path to use the correct bin. Then when you activate a different version, it deactivates the original (by removing the path). It also adds a nice message to the prompt to remind you which compiler is active.

Thanks for the feedback.

Got it!

Previous version (v1.0.1) offered the option of generating activation scripts, which was subsequently removed by the system's shell detector. (dropped in v1.0.2)
check: https://github.com/kassane/ldcup/commit/86c63a311b81be7d250698dbfc01ae4294711ae9
However, it is possible to get this functionality back again. Compatibility assurance with supported shells.

Please, open an issue describing your experience with the application and suggestions for corrections (if interested).

Recently, I've been looking into the possibility of using symbolic links in master/nightly versions to rename folder path (like, zigup - rename zig-master-<hash> to master). If the user doesn't have the habit of checking ldcup list and tries to uninstall ldcup uninstall ldc2-<latest|master|nightly>, will surely get an error.
However, this is just a hypothetical idea. I'd need time to think about it, in case I don't get any feedback to contribute.
