NAME

6       glib-mkenums - C language enum description generation utility
7

SYNOPSIS

9       glib-mkenums [options...] [files...]
10

DESCRIPTION

12       glib-mkenums is a small perl-script utility that parses C code to
13       extract enum definitions and produces enum descriptions based on text
14       templates specified by the user. Most frequently this script is used to
15       produce C code that contains enum values as strings so programs can
16       provide value name strings for introspection.
17

INVOCATION

19       glib-mkenums takes a list of valid C code files as input. The options
20       specified control the text that is output, certain substitutions are
21       performed on the text templates for keywords enclosed in @ characters.
22
23   Options
24       --fhead text
25              Put out text prior to processing input files.
26
27       --fprod text
28              Put out text everytime a new input file is being processed.
29
30       --ftail text
31              Put out text after all input files have been processed.
32
33       --eprod text
34              Put out text everytime an enum is encountered in the input
35              files.
36
37       --vhead text
38              Put out text before iterating over the set of values of an enum.
39
40       --vprod text
41              Put out text for every value of an enum.
42
43       --vtail text
44              Put out text after iterating over all values of an enum.
45
46       --comments text
47              Template for auto-generated comments, the default (for C code
48              generations) is "/* @comment@ */".
49
50       --template file
51              Read templates from the given file. The templates are enclosed
52              in specially-formatted C comments
53
54
55              /*** BEGIN section ***/
56              /*** END section ***/
57
58
59              where section may be file-header, file-production, file-tail,
60              enumeration-production, value-header, value-production,
61              value-tail or comment.
62
63       --help Print brief help and exit.
64
65       --version
66              Print version and exit.
67
68   Production text substitutions
69       Certain keywords enclosed in @ characters will be substituted in the
70       emitted text. For the substitution examples of the keywords below, the
71       following example enum definition is assumed:
72
73
74       typedef enum
75       {
76         PREFIX_THE_XVALUE    = 1 << 3,
77         PREFIX_ANOTHER_VALUE = 1 << 4
78       } PrefixTheXEnum;
79
80
81
82       @EnumName@
83              The name of the enum currently being processed, enum names are
84              assumed to be properly namespaced and to use mixed
85              capitalization to separate words (e.g. PrefixTheXEnum).
86
87       @enum_name@
88              The enum name with words lowercase and word-separated by
89              underscores (e.g. prefix_the_xenum).
90
91       @ENUMNAME@
92              The enum name with words uppercase and word-separated by
93              underscores (e.g. PREFIX_THE_XENUM).
94
95       @ENUMSHORT@
96              The enum name with words uppercase and word-separated by
97              underscores, prefix stripped (e.g. THE_XENUM).
98
99       @VALUENAME@
100              The enum value name currently being processed with words
101              uppercase and word-separated by underscores, this is the assumed
102              literal notation of enum values in the C sources (e.g.
103              PREFIX_THE_XVALUE).
104
105       @valuenick@
106              A nick name for the enum value currently being processed, this
107              is usually generated by stripping common prefix words of all the
108              enum values of the current enum, the words are lowercase and
109              underscores are substituted by a minus (e.g. the-xvalue).
110
111       @type@ This is substituted either by "enum" or "flags", depending on
112              whether the enum value definitions contained bit-shift operators
113              or not (e.g. flags).
114
115       @Type@ The same as @type@ with the first letter capitalized (e.g.
116              Flags).
117
118       @TYPE@ The same as @type@ with all letters uppercased (e.g. FLAGS).
119
120       @filename@
121              The name of the input file currently being processed (e.g.
122              foo.h).
123
124
125   Trigraph extensions
126       Some C comments are treated specially in the parsed enum definitions,
127       such comments start out with the trigraph sequence /*< and end with the
128       trigraph sequence >*/. Per enum definition, the options "skip" and
129       "flags" can be specified, to indicate this enum definition to be
130       skipped, or for it to be treated as a flags definition, or to specify
131       the common prefix to be stripped from all values to generate value
132       nicknames, respectively. The "lowercase_name" option can be used to
133       specify the word separation used in the *_get_type() function. For
134       instance, /*< lowercase_name=gnome_vfs_uri_hide_options >*/.
135
136       Per value definition, the options "skip" and "nick" are supported. The
137       former causes the value to be skipped, and the latter can be used to
138       specify the otherwise auto-generated nickname. Examples:
139
140
141       typedef enum /*< skip >*/
142       {
143         PREFIX_FOO
144       } PrefixThisEnumWillBeSkipped;
145       typedef enum /*< flags,prefix=PREFIX >*/
146       {
147         PREFIX_THE_ZEROTH_VALUE,    /*< skip >*/
148         PREFIX_THE_FIRST_VALUE,
149         PREFIX_THE_SECOND_VALUE,
150         PREFIX_THE_THIRD_VALUE,     /*< nick=the-last-value >*/
151       } PrefixTheFlagsEnum;
