Here's my (tentative) plan of this project:
This package (guix.el) will include a facility that lets you easily
install (by name or by expression), remove, upgrade, and roll back
packages. Of course, guix.el can also list the available and/or
installed packages.
The command `guix-describe-package' (I haven't come up with a good key
binding yet) can prompt for the name of a package, and display a help
buffer describing the package. The buffer includes the name, version,
source, dependencies, home page, license(s) and other descriptions of
the package.
`M-x guix-list-packages' will bring up a buffer named `*Guix Packages*'
with a list of all packages. You can install or uninstall packages via
this buffer. *Note my attached image for the prototype of this buffer.
The `*Guix Packages*' buffer will list all the packages that Guix knows
about, one on each line, with the following information:
* The package name (e.g., `emacs').
* The package's version number (e.g., `24.3').
* The package's status (installed/available).
* A short description of the package.
The following commands will be available in the `*Guix Packages*' buffer:
`h'
Print a short message summarizing how to use guix.el
(`guix-quick-help').
`?'
`<RET>'
Display a help buffer for the package on the current line
(`guix-describe-package'), similar to the help window
displayed by the `C-h P' command.
`i'
Mark the package on the current line for installation
(`guix-mark-install'). If the package status is `available', this
adds an `I' character to the start of the line; typing `x' (see
below) will download and install the package.
`d'
Mark the package on the current line for deletion
(`guix-mark-delete'). If the package status is `installed', this
adds a `D' character to the start of the line; typing `x' (see
below) will delete the package.
`u'
Remove any installation or deletion mark previously added to the
current line by an `i' or `d' command.
`U'
Mark all package with a newer available version for “upgrading”
(`guix-mark-upgrades'). This places an installation mark on the
new available versions, and a deletion mark on the old installed
versions.
`x'
Download and install all packages marked with `i', and their
dependencies; also, delete all packages marked with `d'
(`guix-execute'). This also removes the marks.
`r'
Refresh the package list (`guix-refresh'). This recomputes the
package list.
`R'
Roll back to the previous generation of the profile
(`guix-roll-back'). This undo the last transaction. (Do we need a
"roll back" mark?)
For example, you can install a package by typing `i' on the line listing
that package, followed by `x'.
One can also use the command `M-x guix-package-install' and `M-x
guix-package-remove' to install/remove a package.
Any comments?
