String

Last updated:

Reference:learnvimscriptthehardway.stevelosh.com

Basic usage

vim

let mystr = 'somestring'
let mystr = 'concatenate ' .. 'strings'
let mystr = mystr[-10]

Split into a list using a separator:

vim

let mylist = split(mystr)       " Space is used by default
let mylist = split(mystr, ',')

By default, the comparison case-sensitiveness depends on user configuration.

Append # to make it case-sensitive, or ? to make it case-insensitive.

vim

mystr ==# 'text'
mystr !=# 'text'

For regex, replace the second = with ~:

vim

mystr =~# '^t'  " Starts with t
mystr !~# '^t'  " Does not start with t

vim

echo len(mystr)
echo tolower('Foo')  " => 'foo'
echo toupper('Foo')  " => 'FOO'
