Little program to generate crystal binding file for C libraries.
see also crystal-lang/crystal_lib
- Install CastXML : https://github.com/CastXML/CastXML
- Clone this repository and enter the project folder
$ crystal build --release src/bindgencr.cr
Not yet complete, but can still generate the binding for sqlite3 and json-c ( perhaps some others )
castxml --castxml-gccxml [HEADER] -o [OUTPUT XML FILE]
bindgencr filename.xml [-n LibName] [-l linkedlib ] [--no-prefix=prefix_]
Usage:
bindgencr [argument] [flags]
Example:
bindgencr json.xml -l json-c -n LibJsonC
Flags:
-h, --help Show this help
-n, --name=NAME The module name ( lib [name] )
-l, --link=LINK The library to link with (@[Link([link]) directive
--no-prefix Remove the functions prefix
It will print the result to stdout for now
See spec and samples folder to see what can be done for now.
TODO:
- Generate basic structure
- Generate simple types, pointers and struct
- Render functions declarations in context
- Add function pointer
- Add arrays
- Add CvQualifiedType
- Add Union
- Add Enumeration
- Add pointer of callback
- More and more
Samples are generated and used using those lines :
castxml --castxml-gccxml /usr/include/sqlite3.h -o samples/sqlite3/libsqlite3.xml
crystal run src/bindgencr.cr -- samples/sqlite3/libsqlite3.xml -l sqlite3 -n LibSqlite3 > samples/sqlite3/lib_sqlite3.cr
crystal run samples/sqlite3/main.cr
castxml --castxml-gccxml /usr/include/json-c/json.h -o samples/jsonc/json.xml
crystal run src/bindgencr.cr -- samples/jsonc/json.xml -l json-c -n LibJsonC > samples/jsonc/lib_jsonc.cr
crystal run samples/jsonc/main.cr
