Vim Techniques 10 - listchars + wrap + list

(my apology for sleepy face, yeah I did sleep less hours these days, but all good :)


This video covers a main topic of "listchars" option which will dictate how things will show when you enable "list" mode via ":set list" while editing your file in vim. Additionally, "wrap" mode via ":set wrap" will complete the whole story.


Thing is "listchars" is the configurable set of characters to be used to show when you enable "list" mode. It has 6 categories of
1. eol - End-of-line
2. space
3. trail - character(s) to show at the end of the line
4. tab
5. extends - in "nowrap" mode, it shows that the line is not shown fully yet, there's more on the right
6. precedes - in "nowrap" mode, it shows the the line is not shown fully yet, there's more on the left


So now you know "wrap" is to complete the whole story by making "extends" and "precedes" category effective.


It has benefit especially when you will submit code to upstream, or either for reviewing. You will be able to detect additional space, or unwanted additional changes locally. So it saves time for reviewers.

If you could guess, this time I'm on native Linux, Ubuntu 20.04. Yes, I switch back and forth between Windows 10 (with WSL 1, I'm not fancy WSL 2), and Ubuntu 20.04 kernel 5.8.0-45-generic.
