Crystal-to-C++ transpiler [WIP]
Generated code can be compiled with c++14 compiler (tested with g++ 6.2.0)
List of supported AST nodes can be found here
You can try it here
CLI Usage
- Compile
src/cppize/transpiler.cr
(it may take some time as itrequire
s Crystal parser) - Launch compiled executable with
-h
flag to view all command line flags
Implemented -fFEATURE
s
Flag | Description |
---|---|
-funsafe-cast |
Tells transpiler to transpile casts to C-style casts instead of static_cast s |
-fprimitive-types |
Tells transpiler to use fundamental C++ types when possible |
-fauto-module-type |
Allows transpiler to detect if module is included ⚠️ This option can slow down transpilation |
-fimplicit-static |
Enables static module methods' calls |
Library Usage
# Initialize transpiler
transpiler = Cppize::Transpiler.new
# Set error and warning callbacks
transpiler.on_warning{|e| puts e.to_s}
transpiler.on_error{|e| puts e.to_s; exit 1}
# Transpile file
transpiled_code = transpiler.parse_and_transpile_file("./file.cpp.cr")
# Transpile code from IO
transpiled_code = transpiler.parse_and_transpile_file(File.open("./file.cpp.cr"),"./file.cpp.cr")
# Transpile code from string
transpiled_code = transpiler.parse_and_transpile_file("def foo; bar(true) end","<test>")
Things to improve in already supported AST nodes
- Improve automatic return
- Improve module type detection (namespace / includable)
Development
Implementing nodes
See src/cppize/nodes/expressions.cr for example
Adding transpile-time macros
See src/cppize/macros/__cpp__.cr for example
