Generic Action Code Language (GACL)
GACL is the language to describe the Detail Code for execution of ROOM Models in eTrice plugin . GACL aims at dealing with all features commonly available in imperative languages , especially Java , C/C++ . It will act as complement of current version of eTrice which uses code written in target language stored in a string as execution code . GACL would make user able to write execution code independent of target language .
Development Details and Core Information
Features of GACL
- Variable Declarations ( with optional initializers ) and Function Declaration .
- Comparison & arithmetic expressions .
- Basic types , and user defined types .
- If-else blocks and ladders .
- For , while , for each , enhanched for each .
- Support for iterators (that can be used by for each loops ) .
- Function Calls with arguments & diff types i.e. ref/value/address .
- type checking and as much as possible implicit type casting .
- Casts corresponding to static casts in C .
Thoughts on Syntax
Although syntax for GACL is still being designed but here are few thought regarding syntax .
- Empty
{}
- Type Declaration
"type" typename [ type | "{" TypeCode "}"]
- VariableDeclaration
[type] varname [ "=" { varname2 | Expression } ] { ";" | "\n" }
- Expression
{ ArithmeticExpression | LogicalExpression }
- ArithmeticExpression
{ Expression { "+" | "-" | "*" | "/" | "**" | "^" | "%" | "div" } Expression } | {Expression { "++" | "--" } } | { { "++" | "--" } Expression }
- LogicalExpression
{ Expression { "<" | "<=" | "==" | ">" | ">=" | "|" | "||" | "&" | "&&" | "^" } Expression }
- Statement
{ Expression | VariableDeclaration }
- StatementList
{ Empty | Statement StatementList }
- Program
{ StatementList}
Disambiguation
The syntax used to specify the grammar in brief is
Things written in double quotes ("") stand as string detacted
