NativeBoost and WKHTML
by Torsten Bergmann May 26, 2014

May 26, 2014

Hi, as there was no responded so far I tried to track the problem deeper and did a short test client in C/C++ to verify if I can call WKHTMLTOPDF there and generate a PDF and to compare to the Pharo/NativeBoost client. Attached is the according CPP file which works and results in a PDF with the google homepage. I also additionally implemented the callback functions in the Pharo wrapper and using the error handling I noticed that the component returns "Failed loading page http:// ..." With that info I compared the C/C++ calls to the Pharo/NativeBoost calls more deeply and found out that in C/C++ the following call for an object setting works (by returning 1): // this returns 1 in C/C++ which is OK int a = wkhtmltopdf_set_object_setting(os, "page", "http://www.google.de"); printf("object set %i",a); while in Pharo the same call fails (by returning 0): "The following call failed and returns 0 instead of 1" self setObjectSetting: 'page' to: 'http://www.google.de' in: os. I checked how I wrapped this API call again and again - it is fine from my side: setObjectSetting: aName to: value in: settings <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^NBFFICallout stdcall: #(int wkhtmltopdf_set_object_setting(wkhtmltopdf_object_settings* settings, char* aName, char* value)) module: 'wkhtmltox.dll' and I still have no idea why it fails. Especially because "wkhtmltopdf_set_object_setting" function is not different from "wkhtmltopdf_set_global_setting" which is exactly the same way wrapped, works and returns 1 in exactly the same example. I would really appreciate if someone could have a second look... To reproduce on Windows: 1. Download the 32 bit version of WKHTML from http://wkhtmltopdf.org and install it 2. Copy the "wkhtmltox.dll" to either the folder of the VM executable or the Windows directory so it can be found 3. Load the package WKHTML2PDF-Core-TorstenBergmann.7 from http://smalltalkhub.com/#!/~TorstenBergmann/WKHTML2PDF into Pharo 3.0#30848 4. Check the Transcript while evaluating: WKPDFLibrary example One can see that within this code #setObjectSetting:to:in: fails while #setGlobalSetting:to:in: works. Maybe I just do not see the obvious. Help is appreciated. Thanks in advance! bye T.

That is an interesting validation error. I don't have enough context to understand what exactly goes wrong here. It is of course a correct observation, as TraitBehavior>>users doesn't exist anymore.

A proposal for the Documentation Section of the new web site
by kilon alios May 26, 2014

May 26, 2014

I propose to add links to the pdfs and hmtls ouputs of both Pharo for the Enterprise and Updated Pharo By Example. I know that both are work in progress , especially UPBE , but it shows that we are an active community that prioritizes documentation for newcomers. Especially PFTE clearly shows that there are loads of useful libraries for Pharo. In case of UPBE it looks like I will finish it by the end of this year and then work on updating for Pharo 4 though its obvious that the work for Pharo 4 will be a tiny fraction of the work I am doing right now. I am also willing to update "Why Pharo" if people want a better presentation. Other than that, the website looks awesome congratulation to people behind it for putting the hard work.

I am interested in events you can trigger in web pages. For example: a user clicks on a button and the script code associated causes a state change in the Document Object Model (DOM) and sends a XHR request (XMLHttpRequest) to the server. The server eventually answers this request, closing the sequence of events. I want to trace these sequences of events from a running application. >> I told Leonardo that the Pharo and Seaside communities are great and he will probably get help from us. > we are :) That's very nice >> So, a simple and quick-to-answer question, what is your Seaside application and how to access the code of it? > > many of web app are private because business oriented. I understand, but it would be nice to have some examples of web applications using script languages, even if I don't have access to all source code. Cheers, Leonardo

In keeping with what we did with Magritte: rename users (and users:) to traitUsers(:) ? Are there external tools using this, or is it only used in image? Stephan
