![]() ![]() Tip:: to see a full list of commands available in the current mode, install help-fns with ELPA, require it (see its doc). Otherwise, Evil uses regular Emacs undo.Ī brief PDF manual is available in the /doc subdirectory.įor those not familiar with vim, here's a quick summary of useful commands. (add-to-list 'load-path "~/.emacs.d/evil") no need with 24Įvil requires UndoTree in the load-path for linear undo and undo branches. In any case, add the following lines to ~/.emacs: If you installed it manually, move Evil to ~/.emacs.d/evil (or somewhere else in your load-path). 4.5 Enter an emacs mode in a given stateĮvil can be downloaded and installed using el-get with: M-x el-get-install RET evil RET, or using Melpa with M-x package-install RET evil RET.Īlternatively, Evil lives in a Git repository.4.3 Load config only when we call evil-mode.4.2 Use keychords to go back to normal mode.My next post will be the definitive guide to bash history. LaTeX source: bash-vi-editing-mode-cheat-sheet.tex.Plain text: bash-vi-editing-mode-cheat-sheet.txt.PDF format: bash-vi-editing-mode-cheat-sheet.pdf.I found that ' CTRL-e' (which switched from vi mode to emacs) got undefined, ' v' got defined which opens the existing command in the editor, and ' which replaces a macro key (char) with the corresponding string. It turned out that the commands documented in vi_keymap.c were all documented in man 3 readline and I didn't find anything new.Īfter that I checked bashline.c source file function initialize_readline to find how the default keyboard shortcuts were changed. To create the cheat sheet, I downloaded bash-2.05b source code and scanned through lib/readline/vi_keymap.c source code file and lib/readline/vi_mode.c to find all the default key bindings. You should check out the cheat sheet for other tips and examples, and try them out! These are really basic examples, and it doesn't get much more complex than this. After you type the command you had forgotten, you may go two commands back in history by typing ' kk' (or ' 2k'), erase the ' #' character which was appended as a comment and execute the command, this makes the whole command look like ' ESC 2k0x ENTER'. No need to erase the current command! You can switch to command mode by hitting ESC and then type ' #' which will send the current command as a comment in the command history. Suppose you typed a long command and remembered that you had to execute another one before it. ![]() You can type ' v' to edit the command in the editor and not on the command line! Suppose you typed a longer command and you noticed that you had made several mistakes, and wanted to do the correction in the vi editor itself. Or even quicker, you can type ' f2r5', where ' f2' moves the cursor right to next occurrence of character ' 2' and ' r5' replaces the character under the cursor with character ' 5'. To do this, you can type ' cw' which means 'change word' and just type out ' arg5': Suppose you wanted to change arg2 to arg5: Now, enter insert mode by hitting ' i' and type ' arg5 ' Hit ' ESC' to switch to command mode and press ' 3' followed by ' B':Īlternatively you could have hit ' B' three times: ' BBB'. $ echo arg1 (want to insert arg5 here) arg2 arg3 arg4 Suppose you have typed a command with a few arguments and want to insert another argument before an argument which is three words backward. The example will be performed on this command: Once you have changed the readline editing mode to vi (by typing set -o vi), you will be working in insert mode. Let ' ' be the position of cursor in insert mode in all the examples and ' ' be the position of cursor in command mode. Here are a few examples with screenshots to illustrate the vi editing mode. In insert mode everything you type gets output to the terminal, but in the command mode the keys are used for various commands. The editing happens in two modes - command mode and insert mode. If you are used to a vi text editor you will feel yourself at home. In your bash shell (to switch back to emacs editing mode, type set -o emacs). ![]() You may inspect your current keyboard mappings with bash's built in bind command:Ībort can be found on "\C-g", "\C-x\C-g", "\M-\C-g".Īccept-line can be found on "\C-j", "\C-m".Īlias-expand-line is not bound to any keys The difference between the two modes is what command each key combination (or key) gets bound to. This time I am going to introduce you to bash's vi editing mode and give out a detailed cheat sheet with the default keyboard mappings for this mode. Emacs editing mode is the default and I already wrote an article and created a cheat sheet for this mode. Bash provides two modes for command line editing - emacs and vi. ![]()
