Vim Cheat SheetPosted on March 6th, 2021Tags:
#vim, #vimscript, #cheat-sheet
There's already a number of cheat sheets out there for Vim and Vimscript, but I rarely find one that works. Or at the very least an easily searchable list with specific keywords describing what a function does. So I made one. (Or at least made a reference that I'll add stuff to when I find neat tricks).
This is largely meant to cover "lesser known" functions, but will cover others that may not be lesser known, purely because I felt like including it, or because it took embarassingly long for me to become aware of its existence.
|Writes to a file, and creates said file if it doesn't exist. Largely useful by being a pure script feature, meaning you don't have to open a buffer to make a new file.||create, write, erase|
|Creates a directory, but it supports several arguments. If the second argument is |
"p", it both creates parent directories as needed, and newer versions of Vim don't throw if the directory exists
|Bang version of |
silent, and it completely discards errors. Put it in front of anything causing an error, and it'll be handled quietly.
|errors, error handling|
|(New Vim only): makes it possible to set the language standard. Not to be confused with |
vim9script, though it's in a similar alley for classic strings
|Potentially familiar, but the second argument supports regex||split|
|Alternative to |
. for string concatenation. Does the exact same thing but with no a mbiguity with the standard access operator, which also happens to be
|String concatenation operator|
|Very magic - means characters are interpreted differently. The major implication here is that you can write () or  groups without needing to escape characters. Same with or - generally, it removes the need for a lot of escaping.||magic, escaping|
|Essentially the opposite of |
\v, but a bit more extreme. Largely useful if you've got a bit of a regex that you'd have to escape. Both
\V can be used in the same string, which makes it exceptionally useful in scripting contexts.
\v still has a lot of uses, notably in
substitute if you need regex, and you've forgotten about
:sm. Function use is much more relevant, however.
|no magic, escaping|
Note: I'm not entirely sure why it's called magic. It just makes interpretation feel slightly more like traditional regex (assuming magic is on).
