Awk to take lines from Plan 9’s /lib/unicode and prepend the actual glyph and a tab: awk ‘{cmd=sprintf(“unicode %s”, $1); cmd | getline c; printf(“%s %s\n”, c, $0)}’

Colored Highlighter - A terminal tool to highlight specific words in your command output with colors
I needed to take a look at some live logs and quickly analyze some old ones, but I couldn’t find anything effective to highlight terms, except for esoteric sed and awk commands.
So I built ch - Colored Highlighter - a simple terminal tool to highlight specific words in your command output with colors. Perfect for tailing logs, debugging, and making command output more readable.

Try it out, all feedback is welcome!

Hmm, gnu.org is slow as heck. Shorter HTML pages load in about ten seconds. This complete AWK manual all in one large HTML page took a full minute: https://www.gnu.org/software/gawk/manual/gawk.html Is there maybe some anti AI shenanigans going on?

In any case, I find the user guide super interesting. My AWK skills are basically non-existent, so I finally decided to change that. This document is incredibly well written and makes it really fun to keep reading and learning. I’m very impressed. So far, I made it to section 1.6, happy to continue.

** Make awk rawk **
A friend online recently replied to something I wrote about awk by saying:

[…] it’s a danged shame [awk] didn’t continue to evolve the way Ruby, Python, PHP have evolved over the decades.

I had exactly this thought while working on my slightly unhinged“lets see if I can implement a basic scheme using awk by writing an assembler and VM in awk,” skwak. Which eventually lead me to start noodling on how to layer in some modern niceties into awk, without breaking awk’s portability.

Then I cleaned up my shell history of all of the invocations I ever made of dkv rm ... to make sure I never ever have this so easily accessible in my shell history (^R):

$ awk '
  /^#/ { ts = $0; next }
  /^dkv rm/ { next }
  { if (ts) print ts; ts=""; print }
' ~/.bash_history > ~/.bash_history.tmp && mv ~/.bash_history.tmp ~/.bash_history && history -r

** Styrofoam cups and awk **
I like writing these posts for my website, but I’ve sat down to write this one like 11 times and it either takes on a tone of totally encompassing dread and dystopian navel gazing or I feel like I’m burying my head in the sand and ignoring reality as it happens around me.

…I finished reading Victor LaValle’s The Changeling. It was engaging, and I was interested in where it was going, but I found that where it went wasn’t interesting. The dialogue and prose were lively and contemporary, which is what r … ⌘ Read more

@prologic@twtxt.net Regarding the new way of generating twt-hashes, to me it makes more sense to use tabs as separator instead of spaces, since the you can just copy/past a line directly from a twtxt-file that already go a tab between timestamp and message. But tabs might be hard to “type” when you are in a terminal, since it will activate autocomplete…🤔

Another thing, it seems that you sugget we only use the domain in the hash-creation and not the full path to the twtxt.txt

Well, it was not a proper fix, more like a duck-tape mend, the right thing to do is to add a BSD branch and fix the calls to BSD’s awk and fmt so they produce the data in the way the rest of the code expects it. #txtnish #gnu #bsd

@mdom@domgoergen.com: I’m using txtnish on FreeBSD and I had to switch it to gawk (not sure why BSD awk fails) and disable color. Just fyi. I didn’t look into it any further.

@nblade@nblade.sdf.org I take a look, it should work with every posix compliant awk, so at least oawk, nawk and gawk should run. What’s the error message? Feel free to add an issue.
