Dinamica EGO Reference

This wiki documents Dinamica EGO's scripting language, execution model, and the functors most commonly needed when building a model — organized here by topic rather than alphabetically, so each section can be read in order as an introduction to that part of the system.

• EGO Script Language — the primary text notation for writing a model: functor calls, constants, containers, the calculator shorthand family, properties, and submodels. Start here for the language itself.
• EGOML Script — the equivalent XML notation, generated by the GUI or written by hand, and its DTD.
• Basic Data Flow — the execution model underneath both notations: how connections and containers determine execution order, independent of whether the model was written as EGO Script, EGOML, or built visually.

• Calculate Functors — Complete Operator Documentation — the full expression language available inside a calculator functor: operators, functions, and the shorthand family (#, ##, $, %, %%).
• Calculate R Expression — embedding R code in a model, including how tables, maps, and values convert between Dinamica and R.
• Calculate Python Expression — embedding Python code in a model, including how tables, maps, and values convert between Dinamica and Python.

• Table Type — the general table format: key and value columns, naming, and type inference.
• Lookup Table Type — the single-key, single-value specialization of Table Type, and its own literal syntax and conversions.
• Manipulating Tables and Lookup Tables — functors and techniques for reading, iterating, restructuring, and computing statistics from tables and lookup tables, from a table with a known shape through to tables with an arbitrary number of columns or keys.

• Useful Tips for Creating Models — practical tips that don't fit neatly under a single functor or language feature.
