A tiny, tiny shell utility.
Many (well, most) times I get a compilation error in my Perl/Raku programs. You know, a syntax error here, a mistyped variable name there…
Fact is that I don’t have a very fancy command line prompt, so it tends to drown between an error message from a previous invocation and the following one, making it hard to see where the latest errors are.
My very basic solution to this is to hit the RETURN key a few times, so
that I can see where the “hole” is. Until some time ago, when I decided
it was enough and thought of this very basic solution, installed as
#!/bin/sh printf '\n\n\n\n\n\n\n' exec "$@"
It just expects to be pre-pended to whatever command line I have to type: it will print the newlines within the first command (if it’s a pipeline) and then hand it completely over to the command itself. So, now, I can write:
newlines perl -c whatevah.pl
and get some handy newlines before my… compilation errors.
