$LABEL$ - stores the wrapped node in a mapping label for easy discovery by other macros $SWITCH$ - chooses the template to use for generation from multiple choices

#DOES MODUL8 HAVE MAPPING CODE#

$MAP_SRCL$ - sets a collection of nodes, each of which should to be used in turn as the current nodes inside the wrapped code $MAP_SRC$ - sets a node to be used as the current node inside the wrapped code Reduction rules are applied to the copied nodes and their children during the process $COPY_SRCL$ - copies the specified collection of nodes and replaces the wrapped code. Reduction rules are applied to the copied node and its children during the process $COPY_SRC$ - copies the specified node and replaces the wrapped node. $LOOP$ - iterate over a collection of nodes and set the current node for each iteration $CALL$ - insert another template at the current position and process it passing in the current node Node macro - is used to control template filling at generation time Reference macro - computes the target (node) of a reference Property macro - computes a value for a property What macros are available in the templates? The developer will select the desired target platform by importing the appropriate extension language.

#DOES MODUL8 HAVE MAPPING GENERATOR#

Have no generator in you language directly and provide generators for each target platform in a separate empty language, which extends the original language. The developer will indicate the intended target platform by setting a flag in her code

Put all the generation rules for different platforms into a single generator, perhaps logically separated into virtual packages and multiple mapping configurations, and use the condition of each rule to activate the rule based on the currently selected target. There are at least two ways you can achieve that: You may want to generate code for several target platforms from the same code-base.

#DOES MODUL8 HAVE MAPPING HOW TO#

How to generate multiple targets from single source? Additionally, each mapping configuration can have its generation process priority specified separately, which gives you more flexibility to tune the generation. Yes, they will all be treated as equal during the generation process. Can I have multiple mapping configurations per generator? If you need several generators for a language, it is advisable to create empty languages that extend your language and in each of these extending languages to define the desired alternative generators. No, MPS only allows one generator per language at the moment. Can I have more generators for a single language?

#DOES MODUL8 HAVE MAPPING FULL#

You can check out full description of the generator algorithm in the generator documentation. The next generation step (if any) will receive the output model of previous generation step as its input. When no applicable rules are found, the generation step stops. The generator during a generation step will iterate over the model and search in the generators of all languages involved in this step for rules applicable to the nodes in the input model. A micro-step is a single-pass model transformation of and input model into a transient (output) model. The template-based model transformation phase consists of one or more micro-steps. The generation process itself consists of steps. Generation gradually converts an input model into an output model, which may or may not be then turned into text with TextGen. How does the generator process the rules? You may alternatively consult the Generator documentation and check out the Generator demos. This document is intended to give answers to the most common questions related to the MPS generator.
