#awk

Tim ChaseMy love for <a href="https://mastodon.bsd.cafe/tags/plaintext" class="mention hashtag" rel="nofollow noopener" target="_blank">#plaintext</a> and <a href="https://mastodon.bsd.cafe/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> (as well as other Unix text-processing tools) was rejuvenated by a recent nerdsnipe¹ problem someone shared.They had a WordGrinder² file which is a container-type format that can hold multiple documents (such as multiple individual chapters of a book) in the same document file. As far as we could tell, there's no native way to flatten all those sub-documents into a flat single file, and there was no way to export them into a multipart output document.Fortunately, that WordGrinder file format is just plaintext. It didn't take more than ~10 minutes to reverse-engineer the basics of the file-format and then cobble together an awk(1) one-liner to do the flattening. Worked perfectly on the first try.⸻ ¹ <a href="https://www.reddit.com/r/commandline/comments/1nkxz4t/is_there_any_way_to_massexport_a_document_set_in/" rel="nofollow noopener" translate="no" target="_blank">https://www.reddit.com/r/commandline/comments/1nkxz4t/is_there_any_way_to_massexport_a_document_set_in/</a>² <a href="http://cowlark.com/wordgrinder/index.html" rel="nofollow noopener" translate="no" target="_blank">http://cowlark.com/wordgrinder/index.html</a>

Space HoboThat <a href="https://teh.entar.net/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> script is someone's fork of `guff` ("a plot(1) device") that I've carried around for a while.

Tim ChaseTIL that modifying NF in <a href="https://mastodon.bsd.cafe/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> has an instant effect, so if you do$ echo a b c | awk '{while (NF){print $(NF--)}}'the post-decrementing removes the entry before the variable gets accessed, resulting in it printing blanks, so instead you have to access the variable before doing the post-decrement:$ echo a b c | awk '{while (NF){print $NF; NF--}}'to print each item in reverse.Which seems weird given what I understand about how post-decrement is *supposed* to work.(HT: <a href="https://oldbytes.space/@drscriptt" class="u-url mention" rel="nofollow noopener" target="_blank">@drscriptt</a> whose <a href="https://mastodon.bsd.cafe/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> sent me down this rabbit-hole of learning)

DrScriptt<a href="https://mastodon.bsd.cafe/@gumnos" class="u-url mention" rel="nofollow noopener" target="_blank">@gumnos</a> That didn't quite work, but I did get it to work.Here's what I have:awk -F. '{for (C=NF;C; C--){printf "%s.", $C}; printf "oid."}'NF-1 was missing a component.I also added curly braces around the 1st printf to make it more obvious what the for loop applied to.I wasn't aware that the for loop only applied to the very next instruction. <a href="https://oldbytes.space/tags/TIL" class="mention hashtag" rel="nofollow noopener" target="_blank">#TIL</a> <a href="https://oldbytes.space/tags/AWK" class="mention hashtag" rel="nofollow noopener" target="_blank">#AWK</a>

Willem Van den Ende - WritingEnjoyed <a href="https://mastodon.social/@kevlin" class="u-url mention" rel="nofollow noopener" target="_blank">@kevlin</a> on 'past and future of programming languages' yesterday. I am an outlier, I programmed in three languages outside the top 20 this week - <a href="https://mastodon.social/tags/elixir" class="mention hashtag" rel="nofollow noopener" target="_blank">#elixir</a>, <a href="https://mastodon.social/tags/lisp" class="mention hashtag" rel="nofollow noopener" target="_blank">#lisp</a> (emacs) and <a href="https://mastodon.social/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> (it comes bundled with most linux, and I have it on mac as well). Strangely enough, a local <a href="https://mastodon.social/tags/llm" class="mention hashtag" rel="nofollow noopener" target="_blank">#llm</a> makes the latter two more approachable. qwen3:30 is quite good at generating awk, and good enough to get almost-working <a href="https://mastodon.social/tags/emacs" class="mention hashtag" rel="nofollow noopener" target="_blank">#emacs</a> lisp.

NoGoo.meHey beloved <a href="https://gts.nogoo.me/tags/nogoome" class="mention hashtag" rel="nofollow noopener" target="_blank">#noGooMe</a> users, A quick reminder that you *must* have the proxy image option unchecked when using this <a href="https://gts.nogoo.me/tags/searxng" class="mention hashtag" rel="nofollow noopener" target="_blank">#SearxNG</a> instance. It can be disabled, if you previously had it enabled, browsing to /preferences, then selecting the "privacy" tab and uncheck the "image proxy" switch. It is disabled by default so any first connection to this instance has the proper setting set up. If you do have it enabled, you’ll quickly be blocked at the firewall level by our <a href="https://gts.nogoo.me/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> AI agent 🤖 My reason for disabling this feature is that it generates loads of requests from the instance IP to the external engines. And this makes those block us really fast. This means that the engines will have *your IP* logged when you search for images, only. Classical text search are still masqueraded with our instance IP.
