NAME
getdefs - AutoGen Definition Extraction Tool
SYNOPSIS
getdefs [opt-name[=value]]...
All arguments are named options.
If no input argument is provided or is set to simply "-", and if stdin is not a tty, then the list of input files will be read from stdin.
DESCRIPTION
This manual page briefly documents the getdefs command. This program extracts AutoGen definitions from a list of source files. Defini-
tions are delimited by "/*=<entry-type> <entry-name>0 and "=*/0. From that, this program creates a definition of the following form:
#line nnn "source-file-name"
entry_type = {
name = entry_name;
...
};
The ellipsis `...' is filled in by text found between the two delimiters, with everything up through the first sequence of asterisks
deleted on every line. Additionally, if the `<entry-name>' is followed by a comma, the word `ifdef' (or `ifndef') and a name `if_name',
then the above entry will appear as:
#ifdef if_name
#line nnn "source-file-name"
entry_type = {
name = entry_name;
...
};
#endif
There are two special "entry types":
* The entry_type enclosure and the name entry will be omitted
and the ellipsis will become top-level definitions.
-- The contents of the comment must be a single getdefs option.
The option name must follow the double hyphen and its argument
will be everything following the name. This is intended for use
with the subblock and listattr options.
OPTIONS
defs-to-get=reg-ex
Regexp to look for after the "/*=".
If you want definitions only from a particular category, or even with names matching particular patterns, then specify this regular
expression for the text that must follow the /*=.
ordering[=file-name], no-ordering
Alphabetize or use named file. The no-ordering form will disable the option. This option is enabled by default.
By default, ordering is alphabetical by the entry name. Use, no-ordering if order is unimportant. Use ordering with no argument to
order without case sensitivity. Use ordering=<file-name> if chronological order is important. getdefs will maintain the text con-
tent of file-name. file-name need not exist.
first-index=first-index
The first index to apply to groups. This option takes an integer number as its argument. The default first-index for this option
is:
0
By default, the first occurrence of a named definition will have an index of zero. Sometimes, that needs to be a reserved value.
Provide this option to specify a different starting point.
input=src-file
Input file to search for defs. This option may appear an unlimited number of times. This option is the default option.
All files that are to be searched for definitions must be named on the command line or read from stdin. If there is only one input
option and it is the string, "-", then the input file list is read from stdin. If a command line argument is not an option name and
does not contain an assignment operator (=), then it defaults to being an input file name. At least one input file must be speci-
fied.
subblock=sub-def
subblock definition names. This option may appear an unlimited number of times.
This option is used to create shorthand entries for nested definitions. For example, with:
using subblock thus --subblock=arg=argname,type,null
and defining an arg thus arg: this, char *
will then expand to: arg = { argname = this; type = "char *"; @;}
The "this, char *" string is separated at the commas, with the white space removed. You may use characters other than commas by
starting the value string with a punctuation character other than a single or double quote character. You may also omit intermedi-
ate values by placing the commas next to each other with no intervening white space. For example, "+mumble++yes+" will expand to:
arg = { argname = mumble; null = "yes"; @;}.
listattr=def
attribute with list of values. This option may appear an unlimited number of times.
This option is used to create shorthand entries for definitions that generally appear several times. That is, they tend to be a
list of values. For example, with:
listattr=foo defined, the text:
foo: this, is, a, multi-list will then expand to:
foo = 'this', 'is', 'a', 'multi-list';
The texts are separated by the commas, with the white space removed. You may use characters other than commas by starting the value
string with a punctuation character other than a single or double quote character.
filelist[=file]
Insert source file names into defs.
Inserts the name of each input file into the output definitions. If no argument is supplied, the format will be:
infile = '%s';
If an argument is supplied, that string will be used for the entry name instead of infile.
Definition insertion options
assign=ag-def
Global assignments. This option may appear an unlimited number of times.
The argument to each copy of this option will be inserted into the output definitions, with only a semicolon attached.
common-assign=ag-def
Assignments common to all blocks. This option may appear an unlimited number of times.
The argument to each copy of this option will be inserted into each output definition, with only a semicolon attached.
copy=file
File(s) to copy into definitions. This option may appear an unlimited number of times.
The content of each file named by these options will be inserted into the output definitions.
srcfile[=file]
Insert source file name into each def.
Inserts the name of the input file where a definition was found into the output definition. If no argument is supplied, the format
will be:
srcfile = '%s';
If an argument is supplied, that string will be used for the entry name instead of srcfile.
linenum[=def-name]
Insert source line number into each def.
Inserts the line number in the input file where a definition was found into the output definition. If no argument is supplied, the
format will be:
linenum = '%s';
If an argument is supplied, that string will be used for the entry name instead of linenum.
Definition output disposition options:
output=file
Output file to open. This option is a member of the autogen class of options.
If you are not sending the output to an AutoGen process, you may name an output file instead.
autogen[=ag-cmd], no-autogen
Invoke AutoGen with defs. The no-autogen form will disable the option. This option is enabled by default. This option is a member
of the autogen class of options.
This is the default output mode. Specifying no-autogen is equivalent to output=-. If you supply an argument to this option, that
program will be started as if it were AutoGen and its standard in will be set to the output definitions of this program.
template=file
Template Name.
Specifies the template name to be used for generating the final output.
agarg=ag-opt
AutoGen Argument. This option may appear an unlimited number of times. This option must not appear in combination with any of the
following options: output.
This is a pass-through argument. It allows you to specify any arbitrary argument to be passed to AutoGen.
base-name=name
Base name for output file(s). This option must not appear in combination with any of the following options: output.
When output is going to AutoGen, a base name must either be supplied or derived. If this option is not supplied, then it is taken
from the template option. If that is not provided either, then it is set to the base name of the current directory.
help Display usage information and exit.
more-help
Extended usage information passed thru pager.
save-opts[=rcfile]
Save the option state to rcfile. The default is the last configuration file listed in the OPTION PRESETS section, below.
load-opts=rcfile, --no-load-opts
Load options from rcfile. The no-load-opts form will disable the loading of earlier RC/INI files. --no-load-opts is handled early,
out of order.
version[={v|c|n}]
Output version of program and exit. The default mode is `v', a simple version. The `c' mode will print copyright information and
`n' will print the full copyright notice.
OPTION PRESETS
Any option that is not marked as not presettable may be preset by loading values from configuration ("RC" or ".INI") file(s). The homerc
file is "/dev/null", unless that is a directory. In that case, the file ".getdefsrc" is searched for within that directory.
