Vim TagQuery

I use VimWiki a lot in my daily life as my personal knowledge base/wiki and journal. I tag my notes extensively but found the built-in tag search in Vim and VimWiki seriously lacking.

It only supports simple searches like:

find all entries that have the tag xyz

But what I wanted, was something like:

find all entries with the tag work AND python AND parsing

So I decided to first build a CLI program in Rust, ctags-query, that could parse and store [ctags files][ctags-file-format] in a way that would allow querying. It was now possible to build a simple query interpreter to do exactly what I wanted:

$ ctags-query 'work & python & parsing'
path/to/fileX:10
path/to/fileY:50
path/to/fileZ:165

$ ctags-query 'work & python & parsing'
path/to/fileX:22
path/to/fileY:90

Integrating it into Vim as a plugin just required building a basic Vimscript layer on top of the Rust CLI tool, which is the code that lives in the vim-tagquery repository. I gave it a basic FZF-based search interface.
