# Usage
|
||||
|
||||
`emacs.pkgs.withPackages` takes a single argument: a function from a package
|
||||
set to a list of packages (the packages that will be available in
|
||||
Emacs). For example,
|
||||
```
|
||||
emacs.pkgs.withPackages (epkgs: [ epkgs.evil epkgs.magit ])
|
||||
```
|
||||
All the packages in the list should come from the provided package
|
||||
set. It is possible to add any package to the list, but the provided
|
||||
set is guaranteed to have consistent dependencies and be built with
|
||||
the correct version of Emacs.
|
||||
|
||||
# Overriding
|
||||
|
||||
`emacs.pkgs.withPackages` inherits the package set which contains it, so the
|
||||
correct way to override the provided package set is to override the
|
||||
set which contains `emacs.pkgs.withPackages`. For example, to override
|
||||
`emacs.pkgs.emacs.pkgs.withPackages`,
|
||||
```
|
||||
let customEmacsPackages =
|
||||
emacs.pkgs.overrideScope' (self: super: {
|
||||
# use a custom version of emacs
|
||||
emacs = ...;
|
||||
# use the unstable MELPA version of magit
|
||||
magit = self.melpaPackages.magit;
|
||||
});
|
||||
in customEmacsPackages.withPackages (epkgs: [ epkgs.evil epkgs.magit ])
|
||||
```
