Emacs scheme-mode indentationThis is a discussion on Emacs scheme-mode indentation within the Scheme forums in Programming Languages category; Is there a way to set the indentation rules for scheme-mode in emacs (21.4.1) just as they are for example in drscheme? The default ones are just bizzare : (define (function arg) (cond ((<condition>) ( <--------- after hitting <TAB>, emacs puts the caret in the position of the paren (the parentheses don't line up) (define (function arg) (cond ((<condition>) ( <------- I'd rather it to be like this (one character to the left).

The meaning of the number put in the scheme-indent-function property is the number of _forms_ that shall be indented slightly more than the normal body forms. For example: #+emacs (put 'my-operator 'scheme-indent-function 3) (my-operator a b c d e f g) (my-operator a b c d e f g) I don't observe your bizarre behavior: (define (function arg) (cond (<condition> <body> <body>) (<condition> <body> <body>) (else <body> <body>))) You should try paredit, it's really worthwhile an add-on to edit lisp code in emacs. With paredit, I didn't even had to type any TAB for the above examples, paredit-mode did indent automatically on RET. -- __Pascal Bourguignon__ http://www.informatimago.com/ READ THIS BEFORE OPENING PACKAGE: According to certain suggested versions of the Grand Unified Theory, the primary particles constituting this product may decay to nothingness within the next four hundred million years. |
