About parsing HTML5

by stephane ducasse

Hi Mohammad We are interested in getting a nice HTML parser. Now I suggest that you have a look at the pharo by example book. It will help you to get started. In particular do you know Sunit? There is a chapter on it in the book. We urge you to write tests for your parser. There were several projects around HTML parsing HTML & CSS Validating Parser on squeaksource.com MCHttpRepository location: 'http://www.squeaksource.com/htmlcssparser' user: 'sd' password: '' If you have a good BNF you should have a look at Smacc which is a compiler compiler else you can have a look at petitParser There was long time ago an HTML parser Probably here MCHttpRepository location: 'http://www.squeaksource.com/Scamper' user: '' password: '' But this is old so it may blow on your face. Let us know if you need help. Stef On Mar 11, 2013, at 3:57 PM, Mohammad Al Houssami (Alumni) <mha53(a)mail.aub.edu> wrote: > If this is the case then I should see the new package I created right?

I suspect you already have another Pharo installation on your system, and that's what you've been running, not the one you downloaded. You're now trying to "open" the .image file you want to work on, from within that old Pharo installation that is somehow already installed on your system. > Im opening the image file using pharo and not the other way around. > Im not sure if I make sense. "Im opening the image file using pharo". A Pharo VM (VM = virtual machine) "opens" the image file. If your thinking is that "pharo" is "opening the image file", then I think that's what is blocking you from seeing what's going wrong. What you're calling "pharo" is already a PharoVM running some image (probably a Pharo-1.0 image, based on Phil's posting). You might be thinking that "pharo" is some IDE that you use to "open" the pharo image. That's not what's going on.

For the record, here is the organization of those files: 1) the .image file > the object memory in binary form. You read it from disk and the VM continues executing the bytecode where it left off (basically picking up the instruction and stack pointers to do so). It is kind of like the hibernate file in Windows. 2) the .changes and .sources files > text files with sources and in the changes, what you typed got appended. It is always possible to take a fresh Pharo image and replay stuff from the .changes file to get back to the same state (useful if one image becomes corrupted).

Re: [Pharo-users] Pharo .image loading issues.

Here is the thing: First, I was able to open your image. With a StackVM. Not a CogVM or PharoVM. So you can do that too. Second, this image of yours (like I suspected given the look) is a Pharo1.0 So, I don't know how you ended up downloading a 1.4 and having a 1.0 image, it isn't possible. See screenshot as proof. So, your code is not lost. You may want to reimport it into a new 1.4 image. I've made a Monticello mcz for you to use if you want to do that (An export of the HTML5-Parser package). I don't know if you have other code around in that image. Enjoy. Phil 2013/3/11 Mohammad Al Houssami (Alumni) <mha53(a)mail.aub.edu> > Isnt this the way to open the image file?

If this is the case then I should see the new package I created right? But when I look for it doesn't show. It's basically in the same state as when I downloaded pharo and run it the first time.
