Vim
vim(1) is a terminal text editor. It is closely related to a family of editors stretching from ed(1) to nvim(1), but vim(1) is both the most commonly available and most visible.
History
ed(1) is a line editor. Originally created by Bell Labs for Unix, GNU ed is a POSIX-compliant implementation.
ex(1) is the extended line editor written for the first Berkeley Software Distribution. It is POSIX-compliant implementation of ed(1).
vi(1) is a visual text editor built on ex(1). Type a colon (:) to enter ex mode.
vim(1) is vi improved.
nvim(1) is a fork of vim(1) with a significantly refactored codebase, including...
- The UI and editor processes are separate, enabling the creation of other (often non-terminal) UIs.
Directory scanning follows modern standards (i.e. XDG on *nix, !AppData on Windows).
- Features moved from third-party plugins were incorporated to the project, generally making user configurations more portable across platforms.
Installation
All *nix distributions will have a POSIX-compliant implementation of ed(1) and vi(1) pre-installed.
Many distributions will also have vim(1) pre-installed. Most will at least offer vim and neovim packages.
For Windows users, while GVim is an option, Neovim is strongly recommended. Chocolatey offers a neovim package.
Tips
Searching for Non-ASCII Characters
Vim regular expressions can use hexadecimal to represent non-ASCII code points, but the syntax differs for literal characters and character classes. To search for the number 0, try /\%x30. But to search for any non-ASCII code point, try /[^\x00-\x7F] (note: the omitted percent sign).
Similar syntax is available for Unicode code points, especially multibyte characters. To search for left curly quotes, try /\%u201c. To search for left or right curly quotes, try /[\u201c-\u201d].
Quoting Words
Affixes can be applied programmatically using word deletion and registers. For example, to quote the currently selected word, use ciw'Ctrl+r"'.
ciw - delete selected word and enter insert mode
' - insert the leading quote mark
Ctrl+r" - insert the contents of the " register, a.k.a. the deleted word
' - insert the trailing quote mark
This method can be used to apply any affixes. To surround an SPSS string variable name with the trimming functions, use ciwrtrim(ltrim(Ctrl+r")).
