Description Emacs Lisp REPL
Author David Smith
Part of Emacs yes

IELM (Interactive Emacs Lisp Mode) is a nice mode that gives you an interactive Emacs Lisp shell (or a REPL if you prefer) that you can use for exploratory programming. You can start it by pressing M-x ielm. You'll be taken to a buffer named "*ielm*", where Emacs Lisp expressions you've entered will be evaluated on pressing the Return key. IELM offers some nice features like tab autocompletion of symbol names and the ability to span an expression over several lines.

Basic setup

IELM is bundled with Emacs by default. No additional setup is required.

Common Customization

One thing that many of the shooters on here don't take into aouccnt when selecting a remote trigger method is the absolute reliability that I get with my Pocket Wizards. Yesterday I shot an event with a very well-known coach of a college football team at one of his youth summer camps. This was a posed shot of the coach with each individual camper, and I had about 3-5 seconds between each shot, and only got one chance for each photo. I fired off 802 photos in a row with a set of Pocket Wizard (MultiMax) and a Nikon SB-800 on a light stand, and got 802 flash fires. That is 100.00% firing reliability, which is exactly what was required in this situation. Do you get that type of reliability with your eBay remotes?Richardp.s. I can post a shot of the setup, although it is so simple it is almost boring.
