I’ve written before about Emacs Registers<\/a> and how you can store the mark in a register with \u3010Ctrl<\/kbd>+x<\/kbd> r<\/kbd> Space<\/kbd>\u3011 register<\/i>. That’s one of those things that’s occasionally useful because you can then jump to that position with \u3010Ctrl<\/kbd>+x<\/kbd> r<\/kbd> j<\/kbd>\u3011 register<\/i> but in my experience, I just don’t use it that often. However, while I was doing exploratory programming<\/a> for my series on executable log records, I found that it was extraordinarily useful. <\/p>\n

As I explained in the exploratory programming<\/a> post, I developed the code by writing some exploratory functions and then trying them out on a record sexpr. I used the same file for the entire series and as I added additional posts to the series, I just added code to the end of the buffer. Then I would try it out on one of the records that were at the top of the buffer. By storing the mark in a register, I was able to quickly return to the end of the record and execute it with \u3010Ctrl<\/kbd>+x<\/kbd> Ctrl<\/kbd>+e<\/kbd>\u3011. Then I could return to the code I was working on by simply going to the end of the buffer with \u3010Meta<\/kbd>+><\/kbd>\u3011. <\/p>\n

None of this is extraordinary or ground breaking but it does show how a simple Emacs command can really speed up development. Without storing the position of the record in a register, I would have had to move to it with a much more complicated series of keystrokes. This is another example of Emacs providing the very tool you need for a specific task. <\/p>\n","protected":false},"excerpt":{"rendered":"
