It makes sure that they know how to + call home. For remote processes a substitute is provided, which + communicates with Emacs on standard output/input instead of using a + socket as the Emacsclient does. + + It provides the commands `with-editor-async-shell-command' and + `with-editor-shell-command', which are intended as replacements for + `async-shell-command' and `shell-command'. They automatically export + `$EDITOR' making sure the executed command uses the current Emacs + instance as "the editor". With a prefix argument these commands + prompt for an alternative environment variable such as `$GIT_EDITOR'. + To always use these variants add this to your init file: + + ┌──── + │ (keymap-global-set "<remap> <async-shell-command>" + │ #'with-editor-async-shell-command) + │ (keymap-global-set "<remap> <shell-command>" + │ #'with-editor-shell-command) + └──── + + Alternatively use the global `shell-command-with-editor-mode', which + always sets `$EDITOR' for all Emacs commands which ultimately use + `shell-command' to asynchronously run some shell command. + + The command `with-editor-export-editor' exports `$EDITOR' or another + such environment variable in `shell-mode', `eshell-mode', `term-mode' + and `vterm-mode' buffers. Use this Emacs command before executing a + shell command which needs the editor set, or always arrange for the + current Emacs instance to be used as editor by adding it to the + appropriate mode hooks: + + ┌──── + │ (add-hook 'shell-mode-hook 'with-editor-export-editor) + │ (add-hook 'eshell-mode-hook 'with-editor-export-editor) + │ (add-hook 'term-exec-hook 'with-editor-export-editor) + │ (add-hook 'vterm-mode-hook 'with-editor-export-editor) + └──── + + Some variants of this function exist, these two forms are equivalent: + + ┌──── + │ (add-hook 'shell-mode-hook + │ (apply-partially 'with-editor-export-editor "GIT_EDITOR")) + │ (add-hook 'shell-mode-hook 'with-editor-export-git-editor) + └──── + + This library can also be used by other packages which need to use the + current Emacs instance as editor. In fact this library was written + for Magit and its `git-commit-mode' and `git-rebase-mode'. Consult + `git-rebase.el' and the related code in `magit-sequence.el' for a + simple example. |
