NAME¶
diameter_make - Diameter dictionary compilation.DESCRIPTION¶
The function codec/2 is used to compile a diameter dictionary file into Erlang source. The resulting source implements the interface diameter requires to encode and decode the dictionary's messages and AVPs. The utility diameterc(1) provides an alternate compilation interface.EXPORTS¶
codec(File :: iolist() | binary(), [Opt]) -> ok | {ok, [Out]} | {error, Reason}
Compile a single dictionary file. The input File can be either a path or
a literal dictionary, the occurrence of newline (ascii NL) or carriage return
(ascii CR) identifying the latter. Opt determines the format of the
results and whether they are written to file or returned, and can have the
following types.
Note that a dictionary's @name, together with the outdir
option, determine the output paths when the return option is not
specified. The @name of a literal input dictionary defaults to
dictionary.
A returned error reason can be converted into a readable string using
format_error/1.
format(Parsed) -> iolist()
- parse | forms | erl | hrl:
- Specifies an output format. Whether the output is returned or written to file depends on whether or not option return is specified. When written to file, the resulting file(s) will have extensions .D, .F, .erl, and .hrl respectively, basenames defaulting to dictionary if the input dictionary is literal and does not specify @name. When returned, results are in the order of the corresponding format options. Format options default to erl and hrl (in this order) if unspecified.
The parse format is an internal representation that can be passed to
flatten/1 and format/1, while the forms format can be
passed to compile:forms/2. The erl and hrl formats are
returned as iolists.
- {include, string()}:
- Prepend the specified directory to the code path. Use to point at beam files compiled from inherited dictionaries, @inherits in a dictionary file creating a beam dependency, not an erl/hrl dependency.
Multiple include options can be specified.
- {outdir, string()}:
- Write generated source to the specified directory. Defaults to the current working directory. Has no effect if option return is specified.
- return:
- Return results in a {ok, [Out]} tuple instead of writing to file and returning ok.
- {name|prefix, string()}:
- Transform the input dictionary before compilation, setting @name or @prefix to the specified string.
- {inherits, string()}:
- Transform the input dictionary before compilation, appending @inherits of the specified string.
Two forms have special meaning:
{inherits, "-"} {inherits, "Prev/Mod"}
The first has the effect of clearing any previous inherits, the second of
replacing a previous inherits of Prev to one of Mod. This allows
the semantics of the input dictionary to be changed without modifying the file
itself.
Multiple inherits options can be specified.
Turns a parsed dictionary, as returned by codec/2, back into the
dictionary format.
flatten(Parsed) -> term()
Reconstitute a parsed dictionary, as returned by codec/2, without using
@inherits. That is, construct an equivalent dictionary in which
all AVP's are definined in the dictionary itself. The return value is also a
parsed dictionary.
format_error(Reason) -> string()
Turn an error reason returned by codec/2 into a readable string.
BUGS¶
Unrecognized options are silently ignored.SEE ALSO¶
