Luarocks build failure, issuing installing neotest and haskell nvim treesitter

[dfontenot]

Neovim version (nvim -v)

v0.10.0

Operating system/version

Arch Linux

How to reproduce the issue

Install Haskell treesitter grammar using :TSUpdate Open nvim and wait for lazy.nvim to try to install neotest-haskell

Expected behaviour

The lazy.nvim install of neotest-haskell to succeed. Additionally, I expected the newest version of neotest to be installed. I see it's installing scm-1, however, that version is much older than the latest neotest build on luarocks.

Actual behaviour

Hey 👋

This is two lazy.nvim issues:

1. It tries to install luarocks dependencies from the dev manifest instead of the root manifest, which is why it's trying to install scm-1 versions of neotest. It should try to install from the root manifest (without the --dev flag) first if the version of the plugin being installed is a semver version.

2. It uses generated mappings to exclude neovim plugins from being installed via luarocks. This appears to be broken now that the neotest-haskell rock has tree-sitter-haskell as a dependency.

I see it's installing scm-1, however, that version is much older than the latest neotest build on luarocks.

That is not true. The scm-1 rockspec was uploaded a year ago, but it installs the latest HEAD instead of a semver version (scm = source code management, e.g. git).
The issue here is that the rockspec lists nvim-treesitter in its dependencies, which has been removed from luarocks because the luarocks package was broken and nvim-treesitter isn't meant to be used as a dependency anymore.
I've opened an issue for that:

• [BUG] scm-1 rockspec still has nvim-treesitter in its dependencies nvim-neotest/neotest#440

As a workaround for the lazy.nvim issues, you can pin neotest-haskell to version 2.0.0.

Closing, as this is not a neotest-haskell bug.

Perfect that seems to have fixed it.

My mistake, did not understand that about luarocks.

How to pin the version?
LazyVim's official doc refers to set config.defaults.version = "2.0.0" , but I don't know how to set it in lua config file. Is there any example?

[mrcjkb]

I don't use LazyVim, so you're best off asking there :)

[Zim-Inn]

Perfect that seems to have fixed it.

How did you solve it? I met the same problem. Can you give me a config lua file example?

Thank you, it works perfectly
