A helpful macro to simplify code typing

Introduction

The TemplateCompletion macro provides a way to expand short letter sequences (templates) to larger text blocks while you are typing text. My aim is to make this process (template completion) as simple and fast as possible.

The idea is to link simple keystroke (backslash for example) with the macro which reads the word to left of insertion point and replaces it with corresponding string. If macro does not know the word it inserts character pressed by user (backslash). This allows user (you) to type character in text.

Installation and testing

  • Unzip TemplateCompletion.zip file into "F:\Program Files\Microsoft Visual Studio\Common\MSDev98\Macros" folder (use the appropriate folder name according to the configuration of your computer).

  • In Visual Studio open "Tools|Customize" dialog.

  • Select "Add-ins and Macro Files" tab, turn on "TemplateCompletion" item in list.

  • Select "Keyboard" tab, set "Category" to "Macros" and "Editor" to "Text", link CompleteTemplateBackSlash command with "\" keystroke (backslash), link ToggleTemplateCompletion command with "Ctrl+\" keystroke.

  • Close "Customize" dialog.

  • Open any C or C++ source file and type in foi\ sequence, it will be expanded to
    for (i = 0; i < ; ++i) {
    }
  • Type in "Hello world\n" sequence. No expansion, backslash is inserted in text.

Configuration

You can temporarily toggle on/off template completion. The ToggleTemplateCompletion command provides this service.

You can change keystroke which invokes completion. The possible choices are "\" (backslash), "`" (back quote), "|" (bar or "Shift+\"), " " (space). My first choice was space, but then I changed my mind and now use backslash. You can also add your own CompleteTemplate* subroutine to the file TemplateCompletion.dsm to support any keystroke you want.

You can change the list of the templates. The templates are added by calls to AddTemplate subroutine. Take a look to "Module initialization" section. You can freely change set of templates. But keep the templates distinct. If two or more templates are the same, the first template will be used in expansion. The AddTemplate subroutine does not warn about duplicated templates.

And you can freely change the code of macro itself.

Additionally I want to bring your attention to "escape sequences" in template expansion. You have some control over text layout and caret position. The examples are in TemplateCompletion.dsm file.

Issues

When you undo template completion in VC editor, you need to execute several "undo" commands to remove expanded text (this is also true for "redo" command). I hope this is minor inconvenience. This behaviour also takes place when macro does not do template completion at all (when you type in, for example, backslash in text). If you try to undo your text typing, the first "undo" command deletes text after backslash, second deletes backslash itself and third deletes text before backslash.

In some configurations VC editor "paste" command breaks after installation of this macro. In that case go to http://support.microsoft.com/directory/article.asp?ID=kb;en-us;Q195009 page and apply its recommendations to msdev.exe. This helped me to make "paste" command to work. I hope this will help you also.

This is very slick, and a lack of this ability has been a major thorn towards my not using VC's editor as my primary. However, I am heavily trained towards using the space bar for my character expansion and find it hard to switch. As such I have always used Ctrl+Space to allow me to force just a space character into place. I didn't see an easy way to assign the space character to the Ctrl+Space keystroke, so I wrote an extension macro to this set, and thought others might find it useful who work the same way I do. (Yes, it's trivial, but maybe I'll save someone 5 minutes.)

<br />
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''<br />
' InsertSpace()<br />
' <br />
' implements template completion<br />
' NOTE: subroutine depends on and affects active document of DevStudio,<br />
'       link it with any keystroke to invoke template completion<br />
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''<br />
sub InsertSpace()<br />
' DESCRIPTION: Link it with any shortcut to invoked insertion of a space.<br />
  ActiveDocument.Selection = " "<br />
end sub<br />


I also wanted auto-brace expansion without having to hit the spacebar first. This is one I know some folks like. The template completion code here also makes this trivial.

<br />
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''<br />
' CompleteAutoBrace()<br />
'<br />
' Implements auto-brace template expansion.<br />
' NOTE: subroutine depends on and affects active document of DevStudio,<br />
'       link it with any keystroke to invoke template completion<br />
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''<br />
sub CompleteAutoBrace()<br />
' DESCRIPTION: Link it with any shortcut to invoke insertion of a brace set.<br />
  ActiveDocument.Selection = "{"<br />
  CompleteTemplateOrInsertChar ActiveDocument, ""<br />
end sub<br />


One of the nice things about the later, is if you use the toggle completion command, this turns off as well.
