' Luckily, the Vim manual had the solution already! ' Refer ':help s%' and see 'Examples' section let line_content = substitute(line_content, ' \w \+ ', ' \u \0 ', 'g ') ' Vim global plugin for capitalizing first letter of each word ' in the current line ' Last Change: Fri 08:23 AM IST ' Maintainer: ' License: ' Make sure we run only once if exists( 'loaded_capitalize ') finish endif let loaded_capitalize = 1 ' Capitalize the first letter of each word function Capitalize() range for line_number in range( a:firstline, a:lastline) Since the function is going to work on a range, we can specify that the function works on a range of lines. We can define a function to perform the transformation - capitalize the first letter of each word, so we can call the function as Capitalize(). Now, let us proceed to write the actual functionality. To avoid running the same script twice and redefining things twice, we use a safeguard by checking for existence of the name 'loaded_capitalize' and closing if the script has been already loaded. html files, then Vim opens the HTML syntax highlighting script for both of the files.

For example, if you open two different files in the same Vim instance and both of them are. A script may be loaded multiple times.Consequently, other people can improve your work and that it will in turn benefit you as well.

Computer science word vs word vim license#

A Vim script or plugin that you write may be useful for many other people as well, so you can specify a license for the script.

The 'License:' header is optional, but highly recommended.

There are 2-3 standard headers mentioned regarding the file such as 'Last Changed:' which explains how old the script is, the 'Maintainer:' info so that users of the script can contact the maintainer of the script regarding any problems or maybe even a note of thanks.

The first line of the file should be a comment explaining what the file is about.

' Last Change: Fri 08:23 AM IST ' Maintainer: ' License: if exists( 'loaded_capitalize ')įinish endif let loaded_capitalize = 1 ' TODO : The real functionality goes in here. ' Vim global plugin for capitalizing first letter of each word ' in the current line. Save the following script as the file capitalize.vim: We will start with the basic template script. So, I can write the text in lower case, and then simply call the function to capitalize. Let us tackle a simple problem - how about capitalizing the first letter of each word in a selected range of lines? The use case is simple - When I write headings in a text document, they look better if they are capitalized, but I'm too lazy to do it myself. This is different from writing the script inline and running immediately as we have done all along. We will now write a Vim script that can be loaded into Vim and then we can call its functionality whenever required. There are many functions available - see 'List manipulation' and 'Dictionary manipulation' sections in :help function-list. That looks like a long procedure, but sometimes, this is much easier to do than cook up some complicated substitute commands!Īt the end of the procedure, the line should look like this:

Type A to insert text at the end of the line.

Type gUl to switch the first letter to upper case.

Type qa in normal mode to start recording the macro named as a.

Position your cursor on the first letter of the first line: tansen is the singer.

One way would be to use a series of substitute commands, such as :s/^\w/\u\0/ but this would require 4 substitution commands and it might not be simple if the substitute command changes parts of the text which we do not want to be changed. End the sentence with 'in Akbar's court.'.

Change the first letter of the sentence to upper case.

Using macros, we can record sequences of commands and then replay it in different contexts.įor example, suppose you had some text like this: There are two ways of creating reusable functionality in Vim - using macros and writing scripts.

If you wish to learn programming, please refer my other free book (). If you have no prior programming experience, you will still be able to understand although it might seem terse. This chapter requires some knowledge of programming. There are two approaches to scripting in Vim - using the built-in Vim scripting language, or using a full-fledged programming language such as Python or Perl which have access to the Vim internals via modules (provided that Vim has been compiled with these options enabled). Scripting basically means using a language where you can specify conditions and actions put together into 'scripts'. What if you wanted to do more than that? For example, to check for conditions such as if GUI version, then use this colorscheme else use this colorscheme? This is where 'scripting' comes in.
