LSL-Plus

LSL Plus

LSL Plus is an offline IDE for editing and debugging of LSL code. LSL Plus is Free/Libre Open Source Software (FLOSS), meaning source is included when you download the software, and you are free to update it and redistribute it.

LSL Plus has the following features:

• Source Level Debugging:
  • set breakpoints
  • single step through code
  • examine variables all the way up the call stack, including global variables
• Typical IDE editor features:
  • source code completions
  • integrated information about types, names of built in function arguments
  • documentation hover support
  • auto indentation
  • syntax highlighting
• A Extensive simulation framework for running multiple scripts and testing concurrency
  • Build an environment with avatars, objects, prims, inventory, etc.
  • Embed any number of scripts in any number of prims
  • Add specialized event handlers to simulate avatar actions or external services (e.g. HTTP servers)
  • Test link message, chat, inter-object email, sensors, touches
• A Unit Testing framework:
  • specify the code entry point you want to test (a function, or a specific handler in a specific state).
  • specify the expect return value, and/or the expected change to the state of global variables
  • specify the external calls you expect the code to make
  • framework executes the code, checks results, displays test results, and test log.
• Meta-language features: split your code up into reusable modules, test them separately. LSL Plus will create the combined, validated scripts for you for upload into Second Life.
• Optimization support: inlining, constant folding, pruning of unused elements.
• Integrated into Eclipse, giving you access to several integrated source code control systems (CVS, Subversion, etc.), Mylyn task management, etc.
• Future directions:
  • Write LSL unit tests in LSL, instead of declaratively
  • Visualization support
  • Improved physics fidelity
  • And bug fixes (it is in late beta)
  • More scripting of Simulator events, for more interesting tests
  • Refactoring support
