Public Methods

public String generateExternalName (Set<String> reservedWords, String baseName)

Convert a Blockly entity name to a legal exportable entity name. Ensure that this is a new name not overlapping any previously defined name. Also check against list of reserved words for the current language and ensure name doesn't collide. The new name will conform to the [_A-Za-z][_A-Za-z0-9]* format that most languages consider legal for variables.

Parameters

reservedWords	Reserved words in the target language.
baseName	The name to convert.

Returns

• A legal variable or procedure name in the target language.

public String generateVariableName (boolean addName)

Return a new variable name that is not yet being used. This will try to generate single letter variable names in the range 'i' to 'z' to start with. If no unique name is located it will try 'i' to 'z', 'a' to 'h', then 'i2' to 'z2' etc. Skip 'l'.

Parameters

addName	Whether to add the new name to the list of variables.

Returns

• New variable name.

public void setVariablePrefix (String variablePrefix)

Sets the prefix that will be attached to external names during generation. Some languages need a '$' or a namespace before all variable names.

Parameters

variablePrefix	The prefix to attach.
