The [syntax for the Expression Language](https://docs.inductiveautomation.com/display/DOC81/Expression+Language+and+Syntax) is entirely documented within the Ignition user manual, as this is entirely defined by Inductive Automation.

On top of the basic syntax and operators, expressions may use many functions, which are [documented in an appendix](https://docs.inductiveautomation.com/display/DOC81/Expression+Functions), and can be supplemented by functions from third party modules. Like [mine](https://forum.inductiveautomation.com/t/automation-professionals-simulation-aids-v2/74934), as an example.

Python and Jython are not documented, except briefly and in examples, in Ignition's User manual, as these are open source components with large and thorough public documentation.
