feature: make config.defaults.version overridable

[alex35mil]

Did you check the docs?

• I have read all the lazy.nvim docs

Is your feature request related to a problem? Please describe.

I assumed that config.defaults.version = "*" is overridable if plugin spec provides version/commit/branch/etc. But apparently, it is not.

Describe the solution you'd like

Make config.defaults.version overridable if a plugin spec explicitly provides version/commit/branch/etc.

Describe alternatives you've considered

At least explicitly mention this behavior in the docs.

Additional context

It is for version, but you have a point that we should ignore the default when any of the props you mentioned is set. Will fix!

It's also already the case for commit and tag. Just not for branch

Just noting here because it was a little confusing to figure out.

I have config.defaults.version = "*", but I wanted to unset it for specific plugins (i.e. use latest git for that plugin, without specifying a commit/tag).

I tried setting version = nil or version = "" in the plugin spec, which didn't work. I guess it just uses the default value again.

Solution was to set branch = "master" (or whatever branch used for development of that plugin) in the plugin spec.

@jn64 You need to set version=false

I just clarified this in the docs as well

Thanks, that makes more sense!

fyi: setting something to nil in lua doesn't do anything.

These two tables are exactly the same in lua: {foo = nil} == {}

Lua doesn't have the notion of undefined key/values like javascript,
so for merging tables that can't be used.
