Huh. Cool. Yeah, that would work (via perl -x ~/.XCompose-ordering). Apparently there aren't any ill effects from even adding the following to .XCompose-ordering:

" #!perl -i.bak @ARGV = ($0); while (<>) { $end = 1 if /^__END__/; print if $end < 2; $end++ if /^"/ and $end; if (eof) { open my $f, "</usr/share/X11/locale/$ENV{LANG}/Compose" or die + "<$!"; print for <$f>; # manipulate the line here close $f; } } __END__ " # normal lines start here # etc. etc.

But I suspect this is just a consequence of .XCompose files just ignoring ill-formed lines. (and not because it accepts multi-line strings -- note that I embedded several double-quotes.)

Another interesting approach I tried was to simply add the following header:

#!/bin/env updater # perl -lanwe '(...the script from before...)' inputfile # ... # the normal output... # ...

~/bin/updater was:

#!/usr/bin/perl use strict; use warnings; my $script = ''; my $out = ''; my ($file) = @ARGV; while (<>) { next unless s/^(#\s*)//; $script .= $_ unless $. == 1; $out .= "$1$_"; } open STDOUT, '>', $file; print $out; open my $pipe, "| $ENV{SHELL}"; print $pipe $script; close $pipe;

(NB. this doesn't make a backup like the other way.) That way, I can make .XCompose-ordering itself executable, and then simply run it to regenerate it. But, it has the advantage that it works for any file format that uses '#' comments.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
