NAME
lcm-gen - code generation tool.

SYNOPSIS

lcm-gen [options] FILE...

DESCRIPTION

lcm-gen is the Lightweight Communications and Marshalling code generation utility. It takes as input one or more .lcm files containing LCM message type definitions, and generates language-specific bindings for marshalling and unmarshalling messages of the specified types. Currently, lcm-gen is capable of generating language bindings for C, C++, Java, Python, Lua, and C#.

GENERAL OPTIONS

-h  Prints some help text and exits.

-t, --tokenize
    Show tokenization.

-d, --debug
    Show parsed files.

--lazy
    Generate output file only if .lcm is newer than output file (or if output file does not already exist).

--package-prefix PFX
    Add package name PFX as a prefix to the declared package.

--version
    Shows version information and exits.

C OPTIONS

-c, --c
    Emit C code.

--c-cpath DIR
    Destination directory for generated .c files. (default: current directory)

--c-hpath DIR
    Destination directory for generated .h files. (default: current directory)

--cinclude DIR
    Generated #include lines reference this directory

--c-no-pubsub DIR
    Do not generate _publish and _subscribe functions. This results in .c and .h files that have no linking dependencies and can be used for just marshalling, separately from liblcm. They still #include <lcm/lcm_coretypes.h>, so you will need to copy that file to the appropriate include path.

--c-typeinfo
    Generate typeinfo functions for each type (experimental).

C++ OPTIONS

-x, --cpp
    Emit C++ code.

--cpp-hpath DIR
    Destination directory for generated .hpp files. (default: current directory)

--cpp-include DIR
    Generated C++ #include lines reference this directory

--cpp-std STD
    Generated files comply with the specified C++ standard. Supported values are: c++98, c++11. Default is c++98.

JAVA OPTIONS

-j, --java
    Emit Java code.

--jpath DIR
    Destination base directory for generated Java files. (default: current directory)

--jmkdir <true|false>
    Automatically create Java source directories (default: true)

--jdecl STR
    String added to class declarations (default: implements lcm.lcm.LCMEncodable)

--jdefaultpkg PKG
    Default Java package if LCM type has no package (default: lcmtypes)

PYTHON OPTIONS

-p, --python
    Emit Python code.

--ppath DIR
    Destination base directory for generated Python files. (default: current directory)

LUA OPTIONS

-l, --lua
    Emit Lua code.

--lpath DIR
    Lua destination directory.

C#.NET OPTIONS

--csharp
    Emit C#.NET code

--csharp-path DIR
    C#.NET destination directory

--csharp-mkdir <true|false>
    Make C#.NET source directories automatically (default: true)

--csharp-strip-dirs <true|false>
    Do not generate folders for default and root namespace (default: false)

--csharp-decl STR
    String added to class declarations (default: " : LCM.LCM.LCMEncodable")

--csharp-root-nsp NSP
    Root C#.NET namespace (wrapper) added before LCM package (default: "")

--csharp-default-nsp NSP
    Default C#.NET namespace if LCM type has no package (default: LCMTypes)
