in reply to Formatting Perl code with Emacs

Perhaps using perltidy is an alternative it does'n - results don't look bad:

sub _get_options { Getopt::Long::Configure('gnu_getopt'); return Getopt::Long::GetOptions( \%Options, qw( version|V debug ) ); }

And perhaps you can configure perltidy to get exactly the result you want :-)

Nice command to invoke perltidy from within emacs:

Type C-x h and then M-1 M-| to run the shell command (perltidy) on the marked region.

    Thank you, but this way is too complicated for me. If you have to run shell command from the text editor to format your code, why don't you run another one to save the file?..

    "If you have to run shell command from the text editor to format your code, why don't you run another one to save the file?.."

    Perhaps a misunderstanding? But it is quite simple:

    • Mark the region that you want to format
    • Apply the described command (Shell command on region: perltidy)
    • Save your stuff

    Alternatively you can run perltidy from the commandline. Then you must rename the resulting formatted file and reload the buffer (M-x revert-buffer).

    IMHO applying the shell command (perltidy) on a region respectively running perltidy from within emacs is convinient - and the results look good.

    Update:

    The macro and the binding to F11:

    (fset 'perltidy "\C-xh\C-[1\C-[|perltidy\C-m") (global-set-key [f11] 'perltidy)

    Run it with F11 or M-x perltidy

    Update2:

    OK, on a Mac F11 isn't a good idea :-(

    (global-set-key [f5] 'perltidy)

    Best regards, Karl

    P.S.: BTW, i think, many stuff posted on PM is formatted with perltidy, from within emacs or vim. See also

      Thanks. Perltidy is quite good, but I don't use it in my coding practice, because I prefer to format my code manually with the editor commands at the same time as I type it. TMTOWTDI.

      It's not that complicated, you can easily bind the whole process to a key!

      Either define and save a macro or search for ready-to-use elisp snippets. There are plenty...
