![]() ![]() You can use keyboard macros à la vim in evil.centimacro to (temporarily) bind any number of macros to any global shortcuts.elmacro, to show keyboard macros as emacs-lisp.Now execute the macro four times with the command C-x e e e e and you get: Variables can be stored in lisp or in registers. You can, however, bind a keyboard macro to whatever you like. To avoid problems caused by overriding existing bindings, the key sequences C-x C-k 0 through C-x C-k 9 and C-x C-k A through C-x C-k Z are reserved for your own keyboard macro bindings. To bind a keyboard macro to a key use C-x C-k b. section Formatting Strings in The Emacs Lisp Reference Manual ). Save Keyboard Macro (`(info "(emacs) Save Keyboard Macro")') Insert the keyboard macro counter value in the buffer ( kmacro-insert-counter ). insert it in the current buffer as lisp code ( M-x insert-kbd-macro).give a name to the most recently defined macro ( C-x C-k n).Hit any other key to get out of the macro repetition. Continue hitting e to call it several times.The macro you have just recorded performs the operation of removing the first occurrence of "a" it can find and then moving point to the next line. Hit C-x ) to finish the recording of our macro.Hit C-e C-f to move point to the beginning of the next line.Let's move point to the beginning of the next line and then stop recording. The first occurrence of "a" of the first line has been deleted. Now, point is right after the first "a" in the text. Hit C-s followed by a to find the first "a". ![]() Note: If you hit C-g or if an error occurs, your keyboard macro recording will stop. Hit C-x ( to start recording your macro.Make sure point is at the start of the buffer. ![]() ![]() You could write a regular expression to do the job, but let's assume you want to use a keyboard macro this time. Suppose you want to remove the first occurrence of the letter "a" on every row in that piece of text. then enter the text in that file's own buffer. If you want to create a file, visit that file with C-x C-f, This buffer is for notes you don't want to save, and for Lisp evaluation. , or Execute a macro or Execute a macro multiple times, using prefix argument Execute a macro until the end of the buffer Example usage The video is only 6 minutes, 15 seconds long so it should be easy to find time for it.Basic Use, or Start defining a macro. The fact that it doesn’t work on a couple of irregular entries doesn’t matter they are easily fixed by hand. Instead of an hour or two of tedious work or programming, Bill converts the first entry while recording his keystrokes and then applies that to all the other entries. Most of the data is converted perfectly but the two outliers are easy to fix by hand and the entire process is much more efficient than converting each datum by hand or writing an app that does the right thing for each entry. That’s exactly what Bill does in his video. If there are one or two outliers in the data, we just convert everything according to the canonical data and fix up the outliers by hand afterwards. Theoretically, this means we can’t write a quick and easy macro to do the conversion but, of course, that is not how we work. Very often when we want to convert a data set to some other format, we have the problem that the source data is not completely regular. I like it because it’s a realistic example. It’s actually a nice example of using keyboard macros to convert raw data into the required form. Bill over at ATMakers has a short video on Why He Uses Emacs. ![]()
