I'd like to know whether there's a way to get Pharo's syntax highlighting in a web app coded in Iliad.
Actually, the framework shouldn't matter, as what I'd need is a plain HTML string of the sort:
<span style="color: rgb(102, 0, 0);">^</span> Set <span
style="color: rgb(0, 0, 153);">withAll:</span> <span
style="color: rgb(102, 0, 0);">self</span>
I'm guessing this is not going to be trivial at all... :)
Pier supports syntax highlighting. An example can be found here: http://book.seaside.st/. This is implemented in the package Pier-Shout (see Lukas Renggli's SqueakSource repository).
We wrote a small, but rather complete syntax highlighter in Pharo for Seaside. It takes a method, parses it and outputs annotated html. You only have to specify some rules in css to change the color of the different AST nodes (selectors, strings, symbols, numbers, keywords, variables).
You will find a complete example in the WebDoc project on squeaksource. Look for the SourceFormatter class, everything you need is there.
There is also a smalltalk lexer for pygments which has a bit more penetration than the smalltalk based alternatives.

I have a CQ5 component where the users can write some text with a richtext editor. It is also possible to paste Image script code into source editor available in RTE.
When I am pasting the source code as below
<div style="background:url('data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='); height:100;width:100;"></div>
into RTE, It's getting converted as shown below and it is not rendering the image.
<div style="background: url('data:image/png; base64,ivborw0kggoaaaansuheugaaaauaaaafcayaaacnbyblaaaaheleqvqi12p4//8/w38giaxdibke0dhxgljnbaao9txl0y4ohwaaaabjru5erkjggg=='); height: 100; width: 100;"> </div>
Has anybody a suggestion what can be the cause of this problem?
I believe the code that is formatting the HTML is in /libs/cq/ui/rte/core/HtmlSerializer.js and/or /libs/cq/ui/rte/core/HtmlProcessor.js so you may need to override that by copying that file to apps as /apps/cq/ui/rte/core/HtmlSerializer.js and/or /libs/cq/ui/rte/core/HtmlProcessor.js. This code is doing toLowerCase in several places, though I don't know specifically where it would be altering a style attribute value. But I suspect it is. One of those files has a comment that seems suspicious:
// IE < 9 will report uppercase style names; hence normalize to
lowercase
So perhaps there is some code added to work around an IE bug that is messing up what you are wanting to do--essentially introducing a different bug while fixing an IE issue.
I'm trying to allow custom "template code" within the source code editor. My code snippets would always look like {* anything here *}. It mostly works, but if used inside an HTML tag things gets scrambled.
I'm already using allowedContent: true, when starting CKEDITOR.
Example:
<p style="{* some "short code" of mine... *}">Text</p>
turns into
<p style="{* some " short="" code"="" of="" mine...="" *}"="">Text</p>
And
<p {* tet_pos_is_inside *}>Fuss</p>
into
<p {*="" tet_pos_is_inside="" *}="">Fuss</p>
Any advise ?
Thanks,
Sebastian
My advise would be to never use them inside tags, it sounds like a nightmare to configure. What is the requirement you are trying to fill with those?
You could go around this issue with pre- and post processing using classes, data attributes and/or custom attributes. For example you could use something like his:
<p class="tet_pos_is_inside_val-12345 foo-val-12345">I love horses</p>
<p data-tet_pos_is_inside="12345" data-foo="">I love bunnies</p>
<p tet_pos_is_inside="12345" foo="">I love cats</p>
Well,
apparently there was a simple solution to solve my current problem:
<p style="{* some 'short code' of mine... *}">Text</p>
works ! Note the use of singe-quotes inside the double quotes.
IOW, as long as there is a <tag attr="val"> then val can be anything except containing more double quotes.
Thanks for the comments.
How would I go about doing this? Putting the following code into the
Markdown generator
gives me the desired output
<div style="float: left"><img src="http://ompldr.org/vaDU5NQ/scrotter.png"/>
</div>
I'm trying not to, kid. Don't act so surprised, Your Highness. You weren't
on any mercy mission this time. Several transmissions were beamed to this
ship by Rebel spies. I want to know what happened to the plans they sent
you. Kid, I've flown from one side of this galaxy to the other.
I've seen a lot of strange stuff, but I've never seen anything to make me
believe there's one all-powerful Force controlling everything.
However, adding this code to my README.md file makes it an inline image instead
of floating.
How could I work around this? Is it a Github bug?
I know this thread's old, but for anyone interested, you can use <img align="left" src="img.jpg"> and <img align="right" src="img.jpg"> to float images on GitHub.
I believe it is a security issue with GitHub. My understanding is they strip all HTML attributes such as style with the execption of perhaps href.
Folks,
I have an image with the following HTML code:
<div unselectable="on" class="x-grid-cell-inner x-unselectable" style="; text-align: right;" id="ext-gen1453">
<img alt=""src="data:image/gif;base64,FRFRFR/GFFFFFFFFFF==" class="x-action-col-icon x-action-col-0 folder-action-add folder-action" data-qtip="Add New Music File" id="ext-gen1300">
When I click on the image it should open a pop up so that I can add new music file, I tried a few things but I am not able to click on that image. Any suggestions?
Thanks a lot
You can click on it by the class or a partial match of the class.
#browser.image(:class=>/folder-action-add folder-action/).click
Here is a list of the identifiers you can use for watir, I think it's mostly the same for watir-webdriver.
So far, you haven't got a consistent way of actually identifying the element. From what you've said in the comments, you've tried the 'text' attribute which doesn't exist, and the 'id' attribute which is auto generated and different every time.
You need to find a way of consistently identifying the element. It's usually preferable to use a semantic class on the element to make styling and testing easier and less brittle. You have a few classes declared, perhaps 'folder-action-add' expresses the intent of the button clearly? If not, you could add one such as 'add-music-file'.
Then you should be able to use watir to select an element by it's class, I'm not familiar with the syntax but at a guess, #browser.image(:class => 'add-music-file') might do the job.
I am trying to mask an element that has some images inside of it, using only css.
i have done this and it works fine in webkit using -webkit-mask-box-image and its doing just what i want, but im having trouble using other browsers.
gecko is supposed to work using mask, and that tag does show up in firebug, but it doesnt actually use the mask.. i've also tried converting the png im using to base64 data uri, but to no avail.
example: http://jsfiddle.net/nNLta/
does anyone know the correct way for doing this?
HTML
<div id='wrap'>
<div class='masked flashing-anim'>
<div class='the-mask' >
<ul>
<li class='blink_1'></li>
<li class='blink_2'></li>
</ul>
</div>
</div>
<div class='the-outline'>
<img src='img/real-stuff.png' height=500 />
</div>
</div>
CSS
#wrap {
position: relative;
}
.the-outline, the-mask {
position: absolute;
top: 0;
}
.the-mask {
height: 500px;
width: 360px;
-webkit-mask-box-image: url(../img/the-mask.png);
-moz-mask-box-image: url(../img/the-mask.png);
-o-mask-box-image: url(../img/the-mask.png);
mask-box-image: url(../img/the-mask.png);
mask: url(data:lotsofchars);
}

Part 1
mask is not the same as mask-box-image unfortunately. If you read the (rather sparse) docs you will see it is applicable to SVG only. More on this later.
Currently Gecko doesn't support 'mask-box-image' - if you search the MDN you'll see it applies to -webkit- only.
Additionally I don't think this is actually spec. Webkit has had this capability/concept for ages (in various forms like -webkit-box-reflect) and I think that it's just a hangover from those days. I'm not sure whether this will even be adopted by all browser vendors (although I hope, and it makes sense that, it will).
Part 2
To use the svg dependant mask: css property you need to create an SVG element and reference that. Here is a guide. I've not used this technique before so I'm afraid that's all the detail I'm going to go into right now.
An alternate option
If you don't need a clever repeating/growing mask why not create a large png and overlay the text/image you wish to hide. I'm not sure I understand what you are ultimately trying to do but this seems pretty simple to me. The obvious issue is when you need the stuff behind the mask to be selectable/interactable (err..interactive that is...); for instance when you wish to apply masking to text or links. A way around this is to use pointer-events:none which is supported in Gecko and Webkit (but nothing else...). Here's more from the MDN
Sorry I don't have better news - if none of the above is helpful please feel free to leave a comment with your specific requirement and we'll see if we can't work around the browser limitations.
Hope this is helpful!
