capnp - compiler for Cap'n Proto data interchange format definition files

TomLee <debian@tomlee.co>
           Wrote this manpage for the Debian system.

compile
       Compile Cap'n Proto schema files & generate corresponding source code in one or more languages.

       OPTIONS-I<dir>, --import-path=<dir>
               Add <dir> to the list of directories searched for non-relative imports (ones that start with a
               '/').

           --no-standard-import
               Do not add any default import paths; use only those specified by -I. Otherwise, typically
               /usr/include and /usr/local/include are added by default.

           -olang[:dir], --output=lang[:dir]
               Generate source code for language <lang> in directory <dir> (default: current directory). <lang>
               actually specifies a plugin to use. If <lang> is a simple word, the compiler for a plugin called
               'capnpc-<lang>' in $PATH. If <lang> is a file path containing slashes, it is interpreted as the
               exact plugin executable file name, and $PATH is not searched.

           --src-prefix=<prefix>
               If a file specified for compilation starts with <prefix>, remove the prefix for the purpose of
               deciding the names of output files. For example, the following command: capnp
               --src-prefix=foo/bar -oc++:corge foo/bar/baz/qux.capnp would generate the files
               corge/baz/qux.capnp.{h,c++}.

   decode
       Decodes one or more encoded Cap'n Proto messages as text. Messages are read from standard input and by
       default are expected to be in standard Cap'n Proto serialization format.

       OPTIONS-I<dir>, --import-path=<dir>
               Add <dir> to the list of directories searched for non-relative imports (ones that start with a
               '/').

           -f, --flat
               Interpret the input as one large single-segment message rather than a stream in standard
               serialization format.

           --no-standard-import
               Do not add any default import paths; use only those specified by -I. Otherwise, typically
               /usr/include and /usr/local/include are added by default.

           -p, --packed
               Expect the input to be packed using standard Cap'n Proto packing, which deflates zero-valued
               bytes.

           --short
               Print in short (non-pretty) format. Each message will be printed on one line, without using
               whitespace to improve readability.

   id
       Generates a unique identifier for Cap'n Proto schema files.

       This manual page documents briefly the capnp command.

       It was written for the Debian distribution because the original program does not have a manual page.

       capnp is wrapper for various tools used to manipulate the Cap'n Proto data interchange format. These
       tools include a definition file compiler, a C++ backend, a decoder for converting Cap'n Proto messages to
       text and a generator for Cap'n Proto definition IDs.

       capnp - compiler for Cap'n Proto data interchange format definition files

       The program follows the usual GNU command line syntax, with long options starting with two dashes (`-').
       A summary of options is included below.

       -IDIR, --import-pathDIR
           Add DIR to the list of directories searched for non-relative imports (ones that start with a '/').

       --no-standard-import
           Do not add any default import paths; use only those specified by -I. Otherwise, typically
           /usr/include and /usr/local/include are added by default.

       --verbose
           Log informational messages to stderr; useful for debugging.

       --help
           Show summary of options.

       --version
           Show version of program.
