in thread combine multiple files into one (line by line)

I don't think he was intending to load the entire file into memory. The trick is to keep an array of open FILEHANDLES and read one line at a time from each...
#!/usr/bin/perl -w use strict; use IO::File; #interleave files, first argument is line count, rest are files. my $lc = shift; my @fhs; foreach (@ARGV) { my $fh = new IO::File; open ($fh, "<$_"); push @fhs, $fh; } while (--$lc) { foreach (@fhs) { print scalar(<$_>); } }

Tested minimally but the path is clear from here I hope.

[Corion]: ... don't support server-side precompilation (which means the client has to compile all templates to Javascript themselves), or are giant frameworks that expect to do everything (which is not what I want)
[Corion]: I feel that there is a talk somewhere in there, either about the structure and parts, or how I used several parts to get a complete whole.
[Corion]: Maybe I can still find something that is compatible with handlebars.js (which has JS precompilation) but allows for two-way data binding (which is great for the UI)
[Corion]: Two-way data binding means that if you change something in a text box, the corresponding variable in your Javascript gets updated immediately as well, and if you then change the variable, the corresponding text box also gets updated
