* emacs/guix-command.el (guix-command-improve-environment-argument): Use "E" for '--expose' and "S" for '--share' to distinguish them from '--expression' and '--system' accordingly. Make '--ad-hoc' an option taking packages instead of a simple switch. (guix-command-rest-argument): Complete shell command instead of packages for '--' argument. (guix-command-additional-arguments): Add fake 'packages' argument. New variable. (guix-command-additional-arguments): Use it. (guix-command-post-process-environment-packages, guix-command-post-process-environment-ad-hoc): New functions. (guix-command-post-processors): Add "environment" command with the new argument processors.

|
||
;;; Commentary:
|
||
|
||
;; This file provides a magit-like popup interface for running guix
|
||
;; commands in Guix REPL. The entry point is "M-x guix". When it is
|
||
;; called the first time, "guix --help" output is parsed and
|
||
;; `guix-COMMAND-action' functions are generated for each available guix
|
||
;; COMMAND. Then a window with these commands is popped up. When a
|
||
;; particular COMMAND is called, "guix COMMAND --help" output is parsed,
|
||
;; and a user get a new popup window with available options for this
|
||
;; command and so on.
|
||
|
||
;; To avoid hard-coding all guix options, actions, etc., as much data is
|
||
;; taken from "guix ... --help" outputs as possible. But this data is
|
||
;; still incomplete: not all long options have short analogs, also
|
||
;; special readers should be used for some options (for example, to
|
||
;; complete package names while prompting for a package). So after
|
||
;; parsing --help output, the arguments are "improved". All arguments
|
||
;; (switches, options and actions) are `guix-command-argument'
|
||
;; structures.
|
||
|
||
;; Only "M-x guix" command is available after this file is loaded. The
|
||
;; rest commands/actions/popups are generated on the fly only when they
|
||
;; are needed (that's why there is a couple of `eval'-s in this file).
|
||
|
||
;; COMMANDS argument is used by many functions in this file. It means a
|
||
;; list of guix commands without "guix" itself, e.g.: ("build"),
|
||
;; ("import" "gnu"). The empty list stands for the plain "guix" without
|
||
;; subcommands.
|
||
|
||
;; All actions in popup windows are divided into 2 groups:
|
||
;;
|
||
;; - 'Popup' actions - used to pop up another window. For example, every
|
||
;; action in the 'guix' or 'guix import' window is a popup action. They
|
||
;; are defined by `guix-command-define-popup-action' macro.
|
||
;;
|
||
;; - 'Execute' actions - used to do something with the command line (to
|
||
;; run a command in Guix REPL or to copy it into kill-ring) constructed
|
||
;; with the current popup. They are defined by
|
||
;; `guix-command-define-execute-action' macro.
