48 # note: the first idnum in a stream should be 1 and subsequent
49 # idnums should not have gaps between values as this will cause
50 # the stream parser to reserve space for the gapped values. An

61 delimited_data ::= 'data' sp '<<' delim lf

66 # declen does not include the lf preceeding the binary data.
68 exact_data ::= 'data' sp declen lf
71 # note: quoted strings are C-style quoting supporting \c for
72 # common escapes of 'c' (e..g \n, \t, \\, \") or \nnn where nnn
73 # is the signed byte value in octal. Note that the only
74 # characters which must actually be escaped to protect the

89 binary_data ::= # file content, not interpreted;
91 sp ::= # ASCII space character;
92 lf ::= # ASCII newline (LF) character;
94 # note: a colon (':') must precede the numerical value assigned to
95 # an idnum. This is to distinguish it from a ref or tag name as
96 # GIT does not permit ':' in ref or tag strings.
99 path ::= # GIT style file path, e.g. "a/b/c";
100 ref ::= # GIT ref name, e.g. "refs/heads/MOZ_GECKO_EXPERIMENT";

102 sha1exp ::= # Any valid GIT SHA1 expression;
103 hexsha1 ::= # SHA1 in hexadecimal format;
