Description
For one of my NSIS projects to download and install products from the Internet, I needed some kind of scripting capabilities to perform certain custom tasks on the machine. Some download Zip files contained Dynamic Link Library's that needed to be registered and some registry keys needed to be written.
I decided that NSIS instructions would be ideal for performing these tasks (e.g. RegDll, WriteRegStr etc) and so I began working on a NSIS Script Parser, which is written in NSIS itself. I didn't realise how much work it involved and in the end I decided it would be much better (and more flexible) to write a wrapper for makensis.exe. I stopped working on the NSIS Script Parser, but for future reference I decided to put up what I had started on here. It works, but you're only limited to about 4 NSIS instructions and two of my own which are 'cut down' versions of MessageBox.
