[dokuwiki] Re: need help with a syntax plugin

Hello

I try to create a plugin for dokuwiki that describes the assignment of
rack-space to customers. My idea was to make it look like this:

<rack name="A5">
<desc>this is rack a5, needs the keys 220N</desc>
<he height="12" [from="2"]>
[[customer xyz]] uses this for whatever
</he>
<he height="12" [from="14"]>
[[customer abc]] uses this for whatever
</he>
</rack>

Now I was able to create a plugin that works on the <rack></rack> tags.
However I'm now struggeling on parsing the other tags as easy as
possible. I was thinking of using addPattern in the connectTo function,
but I'm not sure how to describe the patterns.

If anyone could shed some light on this, I'd greatly appreciate it.

Thank you and kind regards

Use addPattern in postConnect(). Its only called once where as connectTo is called many times. Its actually called by all the other syntax modes to tell them what other syntaxes to allow. Since your extra patterns will only apply to your plugin and its syntax mode it is sensible to do the pattern adding once only in postConnect().


Syntax plugins aren't setup to easily handle entering and exiting other syntax modes from within your syntax mode. You can either take care of that within your handle function or add other plugin components which will only "connectTo" your plugin.

======================================================================
method 1 : addPattern

$this->Lexer->addPattern('<he .*?>', 'plugin_rack');
$this->Lexer->addPattern('</he>', 'plugin_rack');
$this->Lexer->addPattern('[[customer .*?]],'plugin_rack');

======================================================================
method 2: if you don't allow any dokuwiki formatting within your <rack>...</rack> tags use this as its the simplest

$this->Lexer->addSpecialPattern('<rack.*?</rack>', 'plugin_rack');

you need to then pull apart the intervening data and process it yourself

======================================================================
method 3: most complex, use component plugins

plugin_rack_rack -
in connectTo ...

$this->Lexer->addEntryPattern('<rack.*?>(?=.*</rack>)', 'plugin_rack_rack');

in postConnect ...

 $this->Lexer->addExitPattern('</rack>', 'plugin_rack_rack');

plugin_rack_desc -
in connectTo ...

if ($mode == 'plugin_rack_rack') {
$this->Lexer->addEntryPattern('<desc>(?=.*</desc>)', 'plugin_rack_desc');
}

in postConnect ...

 $this->Lexer->addExitPattern('</desc>', 'plugin_rack_desc');

plugin_rack_he -
in connectTo ...

 if ($mode == 'plugin_rack_rack') {
   $this->Lexer->addEntryPattern('<he.*?>(?=</he>)', 'plugin_rack_he');
 }

in postConnect ...

 $this->Lexer->addExitPattern('</he>', 'plugin_rack_he');

plugin_rack_customer -
in connectTo

if ($mode == 'plugin_rack_he') {
$this->Lexer->addSpecialPattern('[[customer .*?]]','plugin_rack_customer');
}

======================================================================

As I said above, if you aren't intending Dokuwiki markup to occur within <rack> ... </rack> then go with the simple option - method 1.

I hope that all made sense :)

Cheers,

Chris
