First of all, I have both MW 1.16 and 1.17 set up with PHP 5.3.5, MySQL 5.5.8 and Apache 2.2.17.
I've wrote a simple $wgExtensionFunction which right now does nothing.
$wgExtensionFunctions[] = "wfTestExtension";
function wfTestExtension() { global $wgParser;
$wgParser->setHook("myTag", "renderTest");
}
function renderTest($input) {
return $input;
}
What I want to do is, if I type <myTag>Blah blah blah</myTag> in the add or edit form, I want to be able to change the contents inside myTag BEFORE saving it to the database. What mechanism should I use for this? I'm assuming hooks? For example, with the ArticleSave hook, the $text var already has the <myTag> stripped out, so there's no way of trying to parse the string and figuring out what it is that was originally inside the <myTag>
I've spent hours trying to find something on Google, but I've almost given up. Any advice at all would be highly appreciated.
Cheers.
Maybe http://www.mediawiki.org/wiki/Manual:Hooks/ParserBeforeStrip would work:
"Used to process the raw wiki code before any internal processing is applied"
This is another "maybe" but you could try using a combination of a template and the {{subst:}} command (see transclusion).

I'm trying to add some lua functionality to my existing conky setup so that repetitive "code" in my conky text can be cleaned up. For example, I have information for each mounted FS, each core, etc. where each row displayed in my panel differs ONLY by one parameter.
My first skeletal, attempt at using lua functions for this seems to run but displays nothing in my panel. I've only found very simple examples to base this on, so I may have made a simple error, but I don't even know how to diagnose it. My code here is modeled after what I HAVE been able to find regarding writing functions, such as this How to implement a basic Lua function in Conky? , but that's about all the depth I've found on the topic except for drawing and cairo examples.
Here's the code added to my conky config, as well as the contents of my functions.lua file
conky.config = {
...
lua_load = '/home/conky-manager/MyConky/functions.lua',
};
conky.text = [[
...
${voffset 5}${lua conky_test 'test'}
...
]]
file - functions.lua
function conky_test(parm1)
return 'result text'
end
What I would expect is to see is "result text" displayed in my panel at the location where that function call appears, but nothing shows.
Is there a log created by conky as it runs, or a way to provide some debug output? Even if I'd made a simple error here, I'd still like to have the ability to diagnose things as my code gets more complex.
Success!
After cobbling info from several articles together, I figured out my basic flaws -
1. Missing a 'conky_main' function,
2. Missing a 'lua_draw_hook_post' to invoke it, and
3. Realizing that if I invoke conky from a terminal, print statements in lua would appear there.
So, for anyone who sees this question and has the same issues, here's the corrected code.
conky.config = {
...
lua_load = '/home/conky-manager/MyConky/functions.lua',
lua_draw_hook_post = "main",
};
conky.text = [[
...
${lua conky_test 'test'}
...
]]
and the proper basics in my functions.lua file
function conky_test(parm1)
return 'result text'
end
function conky_main()
if conky_window == nil then
return
end
end
A few notes:
I still haven't determined if using 'lua_draw_hook_pre' instead of 'lua_draw_hook_post' makes any difference, but it doesn't seem to in this example.
Also, some examples showed actually calling this 'test' function instead of writing a 'main', but the 'main' seemed to have value in checking to see if conky_window existed.
Some examples seemed to state that naming functions with the prefix 'conky_' was required, but then showed examples of calling those functions without the prefix, so I assume the prefix is inferred during the call.
a major note: you should run conky from the directory containing the lua scripts.
I'm using the World of warcraft API. And I want to find an EventMessageFilter. I can do so by calling
ChatFrame_GetMessageEventFilters("event")
And to do this I have to pass a chat event, in my case CHAT_MSG_WHISPER_INFORM.
So according to the API located over at
http://wowprogramming.com/docs/api/ChatFrame_GetMessageEventFilters
This function will return a table. So I named the table and tried to print its content with this code
local myNewTable = filterTable = ChatFrame_GetMessageEventFilters("CHAT_MSG_WHISPER_INFORM")
for i in pairs(myNewTable) do
print(asd[i])
end
And this then prints out something like
function: 00000312498vn27842934c4
I have checked with
type(asd[i])
and it really is a function. But how can I get the content of it? How do I handle it?
I want to find an EventMessageFilter
Can you elaborate? Whose filter are you looking for and what do you intend to do with it?
it really is a function.
That's what this API does: returns a list of functions that are registered as filters for a particular message type (via ChatFrame_AddMessageEventFilter).
But how can I get the content of it?
You can't. The WoW API doesn't offer you any facilities for decompiling functions.
If your intention is to filter chat messages yourself, you don't need to call this function at all. Just call ChatFrame_AddMessageEventFilter to add your filter.
So I managed to solve my problem by removing to current filters that have been put in place by another addon and then just add my own filter. As Mud pointed out. GMEF was supposed to return functions. I now see how this makes sense. But now I have made the code to remove the functions. If you want to re-add them later on, just store them in a variable until you are done but I won't include this in my answer. I also feel like my answer is kinda half off-topic ish. But to answer my own question. It is supposed to return functions and you can't see the contents of these functions. This is the code I used to remove the functions that were put in there by another addon.
function rekkFilters()
local myFilters = ChatFrame_GetMessageEventFilters("CHAT_MSG_WHISPER_INFORM")
for i in pairs(myFilters) do
ChatFrame_RemoveMessageEventFilter("CHAT_MSG_WHISPER_INFORM", myFilters[i])
end
end
local myFilters = ChatFrame_GetMessageEventFilters("CHAT_MSG_WHISPER_INFORM")
rekkFilters()
local myFilters = ChatFrame_GetMessageEventFilters("CHAT_MSG_WHISPER_INFORM")
if myFilters[1] ~= nil then
rekkFilters()
end
I have a CI and jQuery based project. I've got a site searching my db. It consists of a jQueryUI accordion. One section contains input fields for an advanced search and the other section is used to display a html table with results.
The search parameters from the first section are sent to the server using ajax post. This is crunched by the server and either a html styled error message or a html table with results (and later some other stuff such as how many results found, how much time consumed etc.) is returned.
Back on the client jQuery must be able to distinguish between the two. Best would be to be able to transmit another variable 'search_success'. If 'search_success' is false, the error is prepended to section one above the input fields. Otherwise the html block is displayed in section two and jQuery opens section 2.
Right now I'm returning plain html with a 0 or 1 prepended. This first char is chopped off by jQuery and used to distinguish between the two possible results. This is kind of ugly.
After reading this post about sending array using json I thought about addressing this problem in json.
I intended to build something like
echo json_encode(array('search_success' => $search_success, 'html' => $html));
This would alow for nice structuring of the data. Problem now is, my 'html' is not a simple php variable but a view:
<?php
$template = array('table_open' => '<table id="table" data-url="'.base_url().'">');
$this->table->set_template($template);
$this->table->set_heading($table_header);
echo $this->table->generate($table);
?>
This view could also get a lot more complicated. Of course I could abandon the CI MVC and store the whole html in a php string which I could transform to json with the above code. However, this would defeat the purpose of storing the whole html part in a view.
Is there a way to wrap my whole view in json without relinquishing my view architecture?
Or what approach would be more suitable to the problem?
Thanks, singultus
To bring this topic to an end, the answer is simple:
$json['html'] = $this->load->view('myfile', '', true); // 3. param 'true'!
$json['other_stuff'] = $other stuff;
echo json_encode($json);
See here at the very end. This approach allows for a nicely structured response to the server.

currently ironing out a way to parse the data of a page: http://www.foundationfinder.ch/
i love to do it in Perl: Well - i am just musing which is the best way to do the job.
Guess that i am in front of a nice learning curve. ;) This task will give me some nice Perl lessions. At the moment it goes abit over my head...;-)
So here is a sample-page:
... and as i thought i can find all 790 resultpages within a certain range between Id= 0 and Id= 100000 i thought, that i can go the way with a loop:
http://www.foundationfinder.ch/ShowDetails.php?Id=11233&InterfaceLanguage=&Type=Html
http://www.foundationfinder.ch/ShowDetails.php?Id=927&InterfaceLanguage=1&Type=Html
http://www.foundationfinder.ch/ShowDetails.php?Id=949&InterfaceLanguage=1&Type=Html
http://www.foundationfinder.ch/ShowDetails.php?Id=20011&InterfaceLanguage=1&Type=Html
http://www.foundationfinder.ch/ShowDetails.php?Id=10579&InterfaceLanguage=1&Type=Html
i thought i can go the Perl-Way but i am not very very sure: I was trying to use LWP::UserAgent on the same URLs [see below] with different query arguments, and i am wondering if LWP::UserAgent provides a way for us to loop through the query arguments? I am not sure that LWP::UserAgent has a method for us to do that. Well - i sometimes heard that it is easier to use Mechanize. But is it really easier!?
BTW; But if i am going the PHP way i could do it with Curl - couldnt i!?
Here is my approach: I tried to figure it out. And i digged deeper in the Manpages and Howtos. We can have a loop constructing the URLs and use Curl - repeatedly
As noted above: here we have some resultpages;
http://www.foundationfinder.ch/ShowDetails.php?Id=11233&InterfaceLanguage=&Type=Html
http://www.foundationfinder.ch/ShowDetails.php?Id=927&InterfaceLanguage=1&Type=Html
Alternatively we can add a request_prepare handler that computes and add the query
arguments before we send out the request.
Again: What is aimed: i want to parse the data and afterwards i want to store it in a local MySQL-database
should i define a extern_uid !?
and go like this:
for my $i (0..10000) {
$ua->get('http://www.foundationfinder.ch/ShowDetails.php?Id=', id => 21, extern_uid => $i);
# process reply
}
Well but now i get stuck- i need help - can i do the job like this!?
regards

Dont do it like this. Use HTTP live headers (Firefox Plugin) or eqv. to see what the javasript does behind the scenes while you select what you need from here to get to that page (with the table).
To get the data from the table, use HTML::TableExtract or HTML::TreeBuilder::XPath if you want to use XPath
If you do want to iterate over the queries, just create another var:
my $a = 'http://www.foundationfinder.ch/ShowDetails.php?Id=' . $q . '&InterfaceLanguage=&Type=Html';
and increment $q as you go, make sure the page is valid before trying to load it with get
I want to be able to parse specific content from a website into a mySQL database. For example, on site http://allrecipes.com/Recipe/Fluffy-Pancakes-2/Detail.aspx I want to parse into my database (which has a table with columns RecipeName, Ingredients 1-10).
So basically my database will contain the name and all the ingredients for that recipe. There is no need to edit the content, simply parse them in as is (i.e. 3/4 cup milk) since i am using character in my database.
How exactly do I go about doing this? I was looking a pre-built parsers and it seems its tough to find one that's easy to use since I am fairly new to programming. Of course, I can manually enter values in but I want to parse them in.
Would it be possible to just parse this content and write a file that has a RecipieName, Ingredient string which I can then parse into my database? Or should I just do it directly into the database? I am unsure as to how to connect a database to a parser also directly, but I might be able to find some information online.
Basically, I am looking for help on how to exactly go about doing this since I am not very well versed in programming and this seems to be a lot more complicated than it might be.
I am using Java as my main language right now, although I can't say I am very good at it. But I should be able to understand the basic concepts.
Any suggestions on what parser to use or how to do this?
Thanks!
This is how I would do it in PHP. This is almost certainly NOT the most efficient way to do it, nor has it been debugged.
function parseHTML($rawHTML){
$startPosition = strpos($rawHTML,'<div class="ingredients"'); //Find the position of the beginning of the ingredients list, return the character number.
$endPosition = strpos($rawHTML,'</div>',$startPosition); //Find the position of the end of the ingredients list, begin searching from the beginning of the list (found in step 1)
$relevantPart = substr($rawHTML,$startPosition,$endPosition); //Isolate the ingredients list
$parsedString = strip_tags($relevantPart); //Strip the HTML tags off of the ingredients list
return $parsedString;
}
Still to be done: You say you have a mySQL database with 10 separate ingredients columns. This code outputs everything as one big string. You would have to change the strip_tags($relevantPart) function to strip_tags($relevantPart,"<li>"). That would let the <li> tags through. Then, you would have to loop through every <li> tag, performing a similar function to this. It shouldn't be too hard, but I don't feel comfortable writing it with no functioning PHP server.
