in thread Programs that write programs

<snark>

$ perl -e'' No code specified for -e.

</snark> :)

Update: Hm, seems to work fine with a file:

$ perl -w /tmp/empty.pl

Update 2: Nevermind, moritz is a clever boy, and laziness (leaving out whitespace) is not always a virtue.

Update 3: I think I prefer the symmetry and perl purity of: echo -n | perl | perl | perl | echo -n

    Ah, but if it outputs nothing, how can you then run that nothing? In other words, outputting nothing, is the same as not outputting anything. Surely that's a no-program. Hrm... I wonder if it's considered a element in the set of all possible quines or not.

[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
[Corion]: That is a horrible approach that was also taken by Access, but if you have hooks that prevent automatic saving to the database, it is incredibly handy
