Guidelines

• Embedded field
• Easy to use
• Simple C code generation (no C Object)
• Standard UML input model (no complex UML profile)

Features

• Header files generated from model elements:
  • Classes
  • Datatype
  • Enumeration
• Source files generated from model classes
• Generated files respect the package structure
• Comments generated from comment model elements
• Function declaration and definition
• Global variables
• Visibility management for function declarations and global variables
  • In header file, if public
  • In source file, if private
• Multiplicity management for variables and parameters
• Import management
• Structure and enumeration generation

Installation

The installation process is described on the installing a module web page.

Contribute!

• Access to the project sources using the Team Project Set file of the UML 2.1 to C generator module. Understand how to use this file reading the tutorial: how to get and modify generator module sources.
• To report a bug, use the Acceleo module tracker.

How to use the generator?

Create a Module Launcher Chain

In a project (C project), containing the input UML model, clic on "New > Other..." and select "Module Launcher" on the Acceleo folder:

Then, select the UML 2.1 to C generation module:

Then, give a name to your new chain:

Finally, enter the 3 parameters required by this generation module:

• The error log file
• The output source folder
• The input UML model

Launch the generation

To launch the generation process, right click on the chain, then "Launch":

Upon the generation process completed, the generated sources should appear on the specified output folder.

Optional parameters

Several parameters can be set to personalize the generation:

Property name	Description	Default value
gen.comment.date	Enable/disable the date/time generation in code heading comments	true
tuple.array.length	Set the default array length for attributes with unlimited multiplicity (*)	20
tuple.string.length	Set the default String length for string attributes without default value	20

To precise such parameters to the generation module, add a property file (with .properties extension) next to the chain you created to launch the generation. For example, you can create a file UML2C.properties with the following content:

# Remove the generation date in the generated file heading
gen.comment.date=true

# Default array length for attributes with unlimited multiplicity (*)
tuple.array.length=200
# Default String length for String attributes without default value
tuple.string.length=75
