reloading mode

[Alex Polite]

I'm altering a mode (transcript.el). Restarting emacs after every edit
to the mode file is very tedious. What's the right way of doing it?

You can put your cursor at or after the closing bracket in the
expression and hit 'C-M-x' to run `eval-defun' and, as such, execute the
changed code.

Alternately, `M-x eval-buffer' in the mode buffer will run all the code
there, changing the definitions at runtime.

Finally, you can `M-x load-file', then specify which Lisp file to load,
or even `M-x byte-compile-file' to byte-compile it before you load it.


Anyway, if you change a function, or whatever, you can simply execute
that Lisp code at runtime and the change takes immediate effect within
Emacs.

C-M-x is used *inside* the expression to evaluate.  C-x C-e is used
after the closing parenthesis.

One other difference is that C-M-x only evaluates top-level
expressions, but C-x C-e can be used inside expressions, too.

C-M-x handles defvar specially, I think that C-x C-e does not.
(The special handling means that changing the value in a defvar and
then doing C-M-x in it changes the value of the variable in Emacs,
although the standard definition of defvar does not change the
variable's value, if it already has one.)

I'm way over my head here, but is there anything useful from

C-h a
load

? I don't know what I'm looking at myself.  daveA

I found load-file but that doesn't do the trick.

I concur, and I haven't found anything better than restarting emacs.
To save time, I sometimes edit in one emacs and then do my testing in
another emacs that just loads the code defining the new mode.

Is "doesn't do the trick" the best description you can come up with?
I must say, I feel like ti doesn't give me nearly enough clues to start
helping you solve your problem.

I don't know much about these things, but can't you just M-x load-file
filename RET?

Or you can evaluate all definitions as you change them with C-M-x (or
C-x C-e should that buffer be in a non-Lispy mode).
