Since @filename@ contains the full filename as given to the glib-mkenum command, possibly including path elements (e.g. when using a non-srcdir build), it is unsuitable to use in a #include statement in the generated file if one wants to distribute it. This patch adds @basename@ which expands to the base name of the input filename. Bug #587307.

.SH NAME
|
|
glib-mkenums \- C language enum description generation utility
|
|
.SH SYNOPSIS
|
|
|
|
\fBglib-mkenums\fP [\fIoptions\fP] [\fIfiles...\fP]
|
|
|
|
.SH DESCRIPTION
|
|
\fBglib-mkenums\fP is a small perl-script utility that parses C code to extract enum
|
|
definitions and produces enum descriptions based on text templates specified
|
|
by the user. Most frequently this script is used to produce C code that contains
|
|
enum values as strings so programs can provide value name strings for introspection.
|
|
|
|
.SH INVOCATION
|
|
|
|
\fBglib-mkenums\fP takes a list of valid C code files as input. The options
|
|
specified control the text that is output, certain substitutions are performed
|
|
on the text templates for keywords enclosed in @ characters.
|
|
|
|
|
|

.SS Production text substitutions
|
|
Certain keywords enclosed in @ characters will be substituted in the outputted
|
|
text. For the substitution examples of the keywords below, the following example
|
|
enum definition is assumed:
|
|
.PP
|
|
.RS
|
|
.nf
|
|
typedef enum
|
|
{
|
|
PREFIX_THE_XVALUE = 1 << 3,
|
|
PREFIX_ANOTHER_VALUE = 1 << 4
|
|
} PrefixTheXEnum;
|
|
.fi
|
|
.RE
|
|
|
|
.TP 12
|
|
\fI@EnumName@
|
|
The name of the enum currently being processed, enum names are assumed to be
|
|
properly namespaced and to use mixed capitalization to separate
|
|
words (e.g. PrefixTheXEnum).
|
|
.TP 12
|
|
\fI@enum_name@
|
|
The enum name with words lowercase and word-separated by underscores (e.g. prefix_the_xenum).
|
|
.TP 12
|
|
\fI@ENUMNAME@
|
|
The enum name with words uppercase and word-separated by underscores (e.g. PREFIX_THE_XENUM).
|
|
.TP 12
|
|
\fI@ENUMSHORT@
|
|
The enum name with words uppercase and word-separated by underscores, prefix stripped (e.g. THE_XENUM).
|
|
.TP 12
|
|
\fI@VALUENAME@
|
|
The enum value name currently being processed with words uppercase and word-separated by underscores,
|
|
this is the assumed literal notation of enum values in the C sources (e.g. PREFIX_THE_XVALUE).
|
|
.TP 12
|
|
\fI@valuenick@
|
|
A nick name for the enum value currently being processed, this is usually generated by stripping
|
|
common prefix words of all the enum values of the current enum, the words are lowercase and
|
|
underscores are substituted by a minus (e.g. the-xvalue).
|
|
.TP 12
|
|
\fI@type@
|
|
This is substituted either by "enum" or "flags", depending on whether the enum value definitions
|
|
contained bit-shift operators or not (e.g. flags).
|
|
.TP 12
|
|
\fI@Type@
|
|
The same as \fI@type@\fP with the first letter capitalized (e.g. Flags).
|
|
.TP 12
|
|
\fI@TYPE@
|
|
The same as \fI@type@\fP with all letters uppercased (e.g. FLAGS).
|
|
.TP 12
|
|
\fI@filename@
|
|
The name of the input file currently being processed (e.g. foo.h).
|
|
.TP 12
|
|
\fI@basename@
|
|
The base name of the input file currently being processed (e.g. foo.h). (Since: 2.22)
|
|
|
|
.SS Trigraph extensions
|
|
Some C comments are treated specially in the parsed enum definitions, such comments
|
|
start out with the trigraph sequence "/*<" and end with the trigraph sequence ">*/".
|
|
.PP
|
|
Per enum definition, the options "skip" and "flags" can be specified, to indicate
|
|
this enum definition to be skipped, or for it to be treated as a flags definition, or
|
|
to specify the common prefix to be stripped from all values to generate value nicknames,
|
|
respectively. The "underscore_name" option can be used to specify the underscorized name
|
|
variant used in the *_get_type() function and *_TYPE_* macro. For instance,
|
|
/*< underscore_name=gnome_vfs_uri_hide_options >*/.
|
|
.PP
|
|
Per value definition, the options "skip" and "nick" are supported. The former causes the
|
|
value to be skipped, and the latter can be used to specify the otherwise auto-generated
|
|
nickname.
|
|
Examples:
|
|
.PP
|
|
.RS
|
|
.nf
|
|
typedef enum /*< skip >*/
|
|
{
|
|
PREFIX_FOO
|
|
} PrefixThisEnumWillBeSkipped;
|
|
typedef enum /*< flags,prefix=PREFIX >*/
|
|
{
|
|
PREFIX_THE_ZEROTH_VALUE, /*< skip >*/
|
|
PREFIX_THE_FIRST_VALUE,
|
|
PREFIX_THE_SECOND_VALUE,
|
|
PREFIX_THE_THIRD_VALUE, /*< nick=the-last-value >*/
|
|
} PrefixTheFlagsEnum;
