In previous post I was writing about snippets' syntax. Now it's time to show you how it works in practice. Video shows building HTML structure with simple tag snippets. Enjoy:

I work as information designer at web-development company in Prague. My responsibilities are to design usable and productive user interfaces for web sites and applications.
Intype is text editor for MS Windows inspired by TextMate. It is a work-in-progress and is not available for download yet. This blog only describes already implemented and incomming features in actual progress. Please, feel free to share some ideas or your feature requests.
Alpha release is planned to first half of september fall/winter of 2006. This is not a sharp dead-line. It may shift in granularity of weeks.

Hello Martin, this looks very interesting. I'm curious how the live mirroring works. Is it implemented in Lua? Or is it in Scintilla's C++ or even another
language? I have tried live updating snippets (http://caladbolg.net/scite.php#snippets) with Lua, but there were too many
variables (especially deleting typed text).

Sorry about the anonymous comment, as the options weren't saved when I previewed it.

mitchell: It's C++. And the answer for this is rather complex.
In implementation, tabstop is called "input placeholder" and mirror "output placeholder". Placeholders are in fact ranges of text organized in a tree (something like AST).
Input has zero or more outputs. When you change tabstop's value, the change is distributed to it's output phs. There is a controller which is taking care of putting the values into right places and synchronizing ranges with changes. It doesn't care of if you are inserting or deleting text. Unless you are outside of any active placeholder. And if you are outside, it simply renders (deactivates) a relevant subtree of placeholders in the tree.
There is some other functionality that allows user to move caret by arrows or mouse to another (non-ambigious) placeholder.

Your article is very informative and helped me further.
Thanks, David
