new
$obj = new Apache::Admin::Config [/path/to/file|handle],
[-indent => $integer], ['-create'], ['-no-comment-grouping'],
['-no-blank-grouping']
Create or read, if given in argument, an apache like configuration file, and return an
Apache::Admin::Config instence.
Arguments:
"/path/to/file"
Path to the configuration file to parse. If none given, create a new one.
"handle"
Instead of specify a path to a file, you can give a reference to an handle that point to an already
openned file. You can do this like this :
my $obj = new Apache::Admin::Config (\*MYHANDLE);
-indent => $integer
If greater than 0, activates the indentation on added lines, the integer tell how many spaces you
went per level of indentation (suggest 4). A negative value means padding with tabulation(s).
-create
If present and path to an unexisting file is given, don't return an error.
-no-comment-grouping
When there are several successive comment-lines, if comment grouping is enabled only one comment item
is created.
If present, disable comment grouping at parsing time. Enabled by default.
-no-blank-grouping
Same as comment grouping but for blank lines.
save
$obj->save(['/path/to/file'|HANDLE], ['-reformat'])
Write modifications to the configuration file. If a path to a file is given, save the modification to
this file instead. You also can give a reference to a filehandle like this :
$conf->save(\*MYHANDLE) or die($conf->error());
Note: If you invoke save() on an object instantiated with a filehandle, you should emptied it before.
Keep in mind that the constructor don't seek the FH to the begin neither before nor after reading it.
dump_raw
$obj->dump_raw
Returns the configuration file as same as it will be if it was saved in a file with the save() method. If
you don't call this method from the top level section, it returns the part of the configuration file that
is under the object's context.
dump_reformat
$obj->dump_raw
Same as dump_raw(), but reformat each line. Usefull used with -indent constructor parameter.
select
@result = $obj->select
(
[-type => $type],
[-name => $name],
[-value => $value],
[-which => $index],
);
@directives = $obj->select('directive');
@sections_foo = $obj->select('section', 'Foo');
This method search in the current context for items (directives, sections, comments...) that correspond
to a properties given by arguments. It returns a list of matched nods.
This method can only be called on an object of type "section". This method search only for elements in
the section pointed by object, and isn't recursive. So elements in sub-sections of current section aren's
seek (it's not a bug).
Arguments:
"type"
Selects item(s) of "type" type.
"name"
Selects item(s) with "name" name.
"value"
Selects item(s) with "value" value.
"which"
Instead of returning a list of items, returns only a single one pointed by index given to the -which
option. Caution, returns an empty string if none selected, so don't cascade your methodes calls like
$obj->select(-which=>0)->name. Index starts at 0.
Method returns a list of item(s) founds. Each items is an Apache::Admin::Config object with same methods
but pointing to a different part of the tree.
directive
@directives = $obj->directive(args...)
Same as calling select('directive', args...)
section
@sections = $obj->section(args...)
Same as calling select('section', args...)
comment
@comments = $obj->comment(args...)
Same as calling select('comment', args...)
blank
@blanks = $obj->blank(args...)
Same as calling select('blank', args...)
set_write_directive
$conf->set_write_directive($code);
Replace the directive writing engine by you own code. Code is call for adding new directives, or when you
tell Apache::Admin::Config to reformat the whole configuration file. See save() and dump_reformat()
methods for more details.
Your handler receives 3 arguments : $self, $name and $value. You can call the "indent()" method to get
the number of spaces to put before the current line (see indent() methods for more details)
$conf->set_write_directive(sub
{
my($self, $name, $value) = @_;
return $self->indent . "$name $value\n";
}
set_write_section
$conf->set_write_section($code);
Same as set_write_directive() but for section.
Your handler receives 3 arguments: $self, $name and $value. You can call the "indent()" method to get the
number of spaces to put before the current line (see indent() methods for more details)
$conf->set_write_section(sub
{
my($self, $name, $value) = @_;
return $self->indent . "<$name $value>\n";
}
set_write_section_closing
$conf->set_write_section_closing($code);
Same as set_write_directive() but for end of sections.
Your handler receives 2 arguments: $self and $name. You can call the "indent()" method to get the number
of spaces to put before the current line (see indent() methods for more details)
$conf->set_write_section_closing(sub
{
my($self, $name) = @_;
return $self->indent . "</$name>\n";
}
set_write_comment
$conf->set_write_comment($code);
Same as set_write_directive() but for comments.
Your handler receives 2 arguments: $self and $value. You can call the "indent()" method to get the number
of spaces to put before the current line (see indent() methods for more details)
$conf->set_write_comment(sub
{
my($self, $value) = @_;
# handle comment grouping
$value =~ s/\n/\n# /g;
return $self->indent . join('#', split(/\n/, $value));
}
set_write_blank
$conf->set_write_blank($code);
Same as set_write_directive() but for blank lines.
Your handler receives 2 arguments: $self and $number.

my($self, $number) = @_;
return $number x "\n";
}
add

value
Returns the value of item pointed by the object if any.

<section target>
<sub section>
directive test
</sub>
</section>

Returns the type of object.
remove
