Vim: pushing built-in features beyond their limits

The situation

Searching can be an efficient way to navigate the current buffer.

The first search commands we learn are usually / and ?. These are seriously cool, especially with the incsearch option enabled which lets us keep typing to refine our search pattern. / and ? really shine when all we want is to jump to something we already have our eyeballs on but they are not fit for every situation:

when we want to search something that's not directly there, those two commands can make us lose context very quickly,
when we need to compare the matches.

Looking for the perfect colorscheme is no doubt part of everyone's experience with text editors and IDEs. For the luckiest among us, that perfect colorscheme will be the one enabled by default or the one that everyone on the internet seems to use. For the less lucky, the quest can be long and eventually lead them to actually build their own "perfect" colorscheme.

As a budding vimmer, it did not take long for me to start looking around for a nice colorscheme. I started my journey with that huge colorscheme test page that crashed so many browsers for so many years. Then, noticing that it did not have every colorscheme, I turned to the scripts section of vim.org and spent too much time looking at too many screenshots and installing too many colorschemes…

vim.org is where I eventually found a bea

This is a list of custom pseudo-text objects for Vim.

Note the use of "pseudo", here. Conceptually, text object are "special" motions but there is no proper mechanism dedicated to creating text objects, specifically. We are left with the generic mechanism succinctly described under the easy-to-miss :help omap-info.

Writing one's own pseudo-text objects and motions is a great way to extend Vim without perverting its nature ;-).
