Best approach to multiple text colors in Spec
I am working on a client in Pharo for which I want to be able to color different pieces of text in different colors (the text stream I'm receiving has ANSI escape codes, and I'll be parsing those and coloring the text appropriately for display). But I have not been able to figure out how to get text color to appear. I set up a simple UI in Spec, using a TextModel for my display. To see if coloring worked, I sent updates to the display via: textToAdd := TextMorph new contents: (Character linefeed asString, text asString). displayField pendingText: (textToAdd textColor: Color lightBlue). displayField accept. I would expect to see the text appear in lightBlue, but it all appears black just like before. Anyone know the solution to coloring text inside Spec widgets?
Hi erik right now I do not know. I'm not sure that spec handles well coloring. Do you have an example that we can play with? Stef Le 18/1/15 18:41, Erik Stayton a écrit :

Hi Stef, I don't have a good minimal example to hand, but my UI is just a simple Spec model with two widgets, the aforementioned TextModel and a TextInputFieldModel that I use to actually take user commands. I am not wedded to Spec, if it doesn't handle colors well. If it is a long-shot to get it working I will pick something else. Would it be better to go for a straight Morph setup? Is that what the system browser uses to get its syntax highlighting/colors? I can put together a minimal example so people can play with Spec and see if it works, but if I'm better off dropping Spec I can jump straight to that. Thoughts?

There is a working example of text coloring in my toy MUD client http://smalltalkhub.com/#!/~AlexanderSvyazin/MudTalk. It actually has support of ANSI escape sequences (only colors yet) :) For now it uses plain Morph, not Spec, AFAIR Spec text model was not flexible enough for my needs and it was too hard to extend for me (but I don't remember the details). This client should work in last release version of Pharo and last development version too (I use development version), just load ConfigurationOfMudTalk and run 'ConfigurationOfMudTalk loadDevelopment'. It is slightly structured pile of code but it's a toy and educational project so I'm trying to use *everything* that I see. On Tue, Jan 20, 2015 at 3:51 AM, ErikStayton <erikstayton@gmail.com> wrote:

I agree and this is something that we will have to think about.

always good to have this kind of resources. Thanks Alexander

Thanks for pointing me to that, I will check it out! Erik On Mon, Jan 19, 2015 at 11:54 PM, Alexander Svyazin [via Smalltalk] < ml-node+s1294792n4800570h51@n4.nabble.com> wrote:
