Hi,
I've made a little patch (attached) to src/edwin/editor.scm that, when
combined with the shell script and Scheme code below, lets me open
Edwin directly on a file from the terminal like so:
$ edwin file.txt
... (new Edwin opens with file.txt loaded)
I'm not submitting this patch for inclusion as it is, it's not very
nice; instead I have questions:
* Is there a way to open Edwin directly on a file without doing this?
* If there currently isn't an official way to do this, I'd appreciate
any comments on how to do this in a less roundabout way so that it
could be submitted for the ``official'' Edwin.
* This starts a new Scheme/Edwin every time, which is OK but sort of
uncool. Is there a way to send a message to a currently running
Edwin to open the file in a new frame or buffer?
Here's the shell script:
#!/bin/bash
EDIT_FILE=$1
CODE_DIR=$HOME/Code/mathoms
SCHEME_FILE=$CODE_DIR/edit-file.scm
/Users/rloveland/bin/scheme --args $EDIT_FILE --load $SCHEME_FILE
And the `edit-file.scm' loaded by Scheme above is:
(load-option 'FORMAT)
(define (build-plausible-filename candidate)
(let ((longname (string-append (->namestring (pwd)) candidate)))
(cond
((file-exists? longname) longname)
((file-exists? candidate) candidate)
(else #f))))
(define (edit-file)
(let* ((args (command-line))
(maybe-file (car args)) ; (list-tail args (- (length args) 1))))
(file (build-plausible-filename maybe-file)))
(format #t "~%;Editing ~A~%" file)
(edit file)))
(edit-file)
Thanks!
Rich
