FAQ: How to Write C# Ops

Before you start

This page assumes that you're running TiXL from an IDE.

Best practices:

• When experimenting, it might be useful to recompile and restart TiXL's editor in Debug Mode before doing any of the steps mentioned on this page. This is important because TiXL will lock all library ops in Release mode as read-only.
• It’s a good idea to always use git and commit or discard local changes.

How can I create a new op?

• We recommend duplicating an existing op.
• You don't need to restart — after duplicating, your IDE should be able to find the new operator. (This has been tested with library and example projects. Handling of user projects by the IDE may differ.)
• Once your new project is created, TiXL will immediately set up a file watch. Every time this file is modified, TiXL will recompile the operator project independently of the IDE. Avoid applying hot-code reloading from the IDE. Once the operator has been compiled by TiXL, it will automatically update all instances.

How can I remove inputs and outputs

• Just remove the respective input definitions from the c# file. You can do this while the Editor is running. TiXL will recompile the project and remove the respective definitions from the .t3ui and .t3 files.
• After recompiling the parameters should disappear from the user interface and connection to it should removed.
• Careful: there is no Undo for this.
