On the Emacs on the pc's in school we can use 'F5' to run a selected piece of perl code. However, when im trying to do this at home it fails. I have installed Emacs and Activeperl on my windows7 machine.
Whenever i try to run a piece of code i get the error 'F5 is undefined'. However, when i look into the .Emacs file i see that the F5 function key is correctly binded to the function perl-eval. This afternoon it worked by putting (defalias 'perl-mode 'cperl-mode)
in my .Emacs file, but when i tried to write code this evening i received again the error 'f5 is undefined'.
Anyone who can help me with this subject? I know i can run my perl code with the cmd tool, but it's much easier when i can run directly from my Emacs :).
Run the "perl" command with the Perl script included in the command line. For example, enter the following command line in a shell window: /home/herong$ perl -e "print 'Hello world! ';" Hello world!
If you have perl installed on your computer, you may debug a perl script by simply typing "alt-x perldb" "perl -d myscript.pl". Once the command is entered, you will see 2 buffers in Emacs, the top buffer is the debugger, the bottom buffer is your perl script.
It looks like your .emacs
is valid, but it could be in the wrong place.
To check where .emacs
should be do:
M-x getenv
RET HOME RET
Which should show something like: (windows xp)
C:\Documents and Settings\YourName\Application Data\
(or windows7)
C:\Users\YourName\Application Data\
If it is the same location as .emacs
then add a debug message to the end of your .emacs
file. e.g.
(message " >------------< This is the one >------------< ")
And restart Emacs and look in the *messages*
buffer.
If it's showing the debug message, the key binding should be available, check it with C-h k F5
Let us know the outcome of these tests.
You can do C-h k F5 in both Emacs instances. It will tell you to which command the key F5 is bound, so you can see the difference. To bind the key on your local computer after you know what to call, use something like:
(add-hook 'perl-mode-hook '(lambda () (local-set-key [f7] 'compile)))
