If anyone’s getting into nginx look into nginxinc/crossplane. That parser is particularly good if you’re trying to analyze or do sophisticated stuff with a huge nginx.conf. I have this one installed in my playground, here’s a quick and dirty demo:

I helped someone with a tmux config. It’s been a while since I’ve used tmux but I’ve since realized it’s better to copy paste tmux list-keys into tmux.conf and reset all shortcuts (for debugging).

tmux list-keys

The help menu (tmux list-keys -N) displays shortcuts with bind-key -N "description".

Sandboxing in systemd? I would’ve shown my (somewhat manual) method but then I was strolling through the GitHub and saw shh (systemd hardening helper). It uses strace to generate suggestions. You’ll need to be extremely careful, playing inside a sandbox summons debugging hell. I tried it briefly.

This graph is from Grafana. It’s moreso for developer operations. I used to use qtiplot for random stuff, but nowadays I use gnuplot for scriptability (not GNU, see demos). Then, there’s Microsoft Excel et al.

The interest in TUIs online is high. In the real world you tend to be constrained and blindfolded by the tools available/allowed. Filtering is peculiar though.

See how the terminal/editor splits? Filtering makes them kiss? Commands that input|output (pipe) work best (compilers, transpilers and code generators). The meta is the limit.

File name, spelling, and dictionary completion exist too. This is tortured, but combining them makes a meta point? The “meta” is hard to convey, but completion doubles as a way of finding, changing, and passing keywords around. Terminals are fair game too. That’s basic completion in a nutshell (minus the magic).

Command line completion is probably another lesser known one. The command line window is minimized, but typing q: (commands) and q/ or q? (search forward/backward) opens it up completely. Wild mode configures its behaviour.

Abbreviations are another completion primitive in Vim. Since it’s full auto, it wants to be magical. <Key> presses and scripts can be replayed. Paired with custom completions and output from external tools, it transforms into advanced witchcraft and/or cursed sorcery. In my case, it just expands acronyms.

Here’s Vim editor thesaurus completion. This kind of completion has its various limitations that I might detail later. I mentioned thesauri in passing but my Internet connection is pitiful and writing about editor meta feels a bit bizarre.

More Vim editor meta? Since posting a video of my LaTeX/Vim shenanigans, queries for tips arrive occasionally. Completion and whole line completion are boilerplate hammers. The more buffers and windows loaded, the more “robust”.
