The `helperFunctions` and `stdenvAdapters` both use the `pkgs` attribute as
input, either to inherit some properties, either to use it as argument.
The `pkgs` binding used in both expressions of the `helperFunctions` and
`stdenvAdapters` is no longer the result of the `applyGlobalOverrides`
function, but the argument of the `pkgsFun` function.
The `pkgsFun` functions is called twice under `applyGlobalOverrides`, and in
both cases, the first argument of `pkgsFun` correspond to the result of
`applyGlobalOverrides`.
Thus, this modification will change the bindings, but the evaluation of
`<nixpkgs>`.
A third call the `pkgsFun` exists under `overridePackages` in the set of all
packages. Previously, the `helperFunctions` and `stdenvAdapaters` would use
the functions defined as part of the default `<nixpkgs>` set. With this
modification, the `helperFunctions` and the `stdenvAdapters` are now using
the fix-point of the newly evaluated package set.
This implies that this modification allow the user to use
`overridePackages`, which is already not recommended for performance
reasons, to override the inputs of the `helperFucntions` and
`stdenvAdapaters` too, where this was not possible before.
- missing cd command
- invoke bundler through nix-shell, so it doesn't need to be on $PATH
Note: running bundix through nix-shell won't work ATM, as the shell sets
SSL_CERT_FILE=/no-cert-file.crt which prevents fetching throug https.
- use version from gemset to simplify updating
- don't break line in meta.description
Setting the GEM_PATH after ruby is started is not reliable enough. In
some cases rubygems would have already loaded and ignore these settings.
Fixes#14048
This reverts commit 0f0805b, because @nbp had concerns about whether
this would be a good idea and pointed out problems with this.
We currently do not have a case where "either" is used in conjunction
with submodules, but I'm reverting it anyway to prevent people from
adding options using that type in that way.
This is now being reviewed in #14053.
