TL;DR: Wählen lohnt sich nicht.

Kurze Erklärung der kommenden Hochrechnungen.

I kept my promise and wrote something in Lisp.

FWIW: Not counting third-party libraries, READMEs and build-related stuff:

This has a few rough edges yet, for which I’m sorry. I’m proud enough to release it though. Please don’t consider this to be “finished software” yet. :-)

Ich finde die Entwicklung nicht gut, aber dieser Blogger hätte 2-3 Ideen, wie man sie aufhält.

Oder man macht halt weiter so.

Als Ergänzung zu meinem vorherigen Maimai vielleicht noch eine Erklärung dazu, was mich am Parlamentarismus eigentlich stört.

Wo bleibt eigentlich die Revolution?

For a reason not worth mentioning here, I would like to write a somewhat more complex awk script in which I would have to explain in detail what I am doing. (If only so that I'll still know next week.) There doesn't seem to be a way to wrap a list of conditions in GNU awk, right?

This is what I tried:

command-that-prints-a-table | awk '
    NR>1 &&                # Skip line 1
    NF>2 &&                # Skip lines with only one column
    substr($1,1,1) != "("  # Skip lines that start with a "("
    { print $1 }
'

Alas, that does not work - awk skips the conditions entirely and only runs print $1. It seems that escaping the newlines does not work either, which makes sense as the end of the lines are comments.

This would work:

command-that-prints-a-table | awk '
# - Skip line 1
# - Skip lines with only one column
# - Skip lines that start with a "("
    NR>1 && NF>2 && substr($1,1,1) != "("  { print $1 }
'

But - my original code has a few more conditions - it is rather annoying to read and maintain. Is there an elegant way to fix this?
