• SimpleScript Part Seven: Binder Skeleton

  In Part Five I was discussing modules: there is a "global module" and any number of additional modules. Each module is associated with a named item, and the only module which is associated with more than one named item is the global module. This means Read More...

• SimpleScript Part Six: Threading Technicalities

  Refresher Course Before you read this, you might want to take a quick refresher on my original posting on the script engine threading model. That was a somewhat simplified (!) description of the actual script engine contract. Let me just sum up: free Read More...

• SimpleScript Part Five: Named Items and Modules

  Named Items "Named items" are what we call the "top level" objects of the host provided object model. WScript in WSH, window in Internet Explorer, Response in ASP, are all named items. A host tells an initialized script engine about named items via the Read More... Posted Thursday, April 22, 2004 5:29 PM by Eric Lippert | 16 Comments Filed under: Scripting, SimpleScript

• SimpleScript Part Four: Finite State Machines and Script Engines

  Last time I said that I'd discuss finite state machines (also sometimes called finite state automata, same thing.) The FSM is a fundamental idea in theoretical computer science because it models computing machinery in a very simple, abstract and general Read More...

• SimpleScript Part Three: Engine Skeleton

  Before I get into today's topic I want to quickly address a minor defect that Raymond Chen (who apparently spends his holiday in Sweden doing remote code-reviews, oddly enough) was good enough to point out to me. It is legal to unload a DLL if the only Read More... Posted Monday, April 05, 2004 5:32 PM by Eric Lippert | 4 Comments Filed under: Scripting, COM Programming, SimpleScript

• SimpleScript Part Two: Class Factories Are Also Boring

  Before I get into it, a Lambda poster pointed me at the NullScript project, which is a very interesting illustration of how reverse engineering works. It's an implementation of a "null" script engine -- an engine with no language -- in ATL, which the Read More...

• SimpleScript Part One: DllMain is Boring

  In talking with our support engineer it's just become more muddled. I'm pretty sure now actually that the customer does not want to build a script engine, but whether they want to build a script editor, a script host or a script debugger is unclear. Before Read More... Posted Wednesday, March 31, 2004 11:01 PM by Eric Lippert | 21 Comments Filed under: Scripting, COM Programming, SimpleScript

• SimpleScript, Part Zero

  I'm going to embark upon something ambitious here. I got an email from Mike, our friendly support engineer on the east coast with the subject line " Need lots of info ". Apparently he was contacted by a customer who wants to implement a new script engine Read More...
