Having the exact same issue. Made my syntax highlighter and it was working perfectly.
Tried it on a large script and RichText just didn’t bother rendering…
I thought it was something being escaped incorrectly so I wasted 20 minutes trying to narrow it down to something before realizing that setting the source to string.rep("print('hi');",200,"\n") caused it to break.
I don’t know what the current limit is but it clearly stops working after a certain number of tags. (Limit seems to change based on how many unique tags there are, but always exists at some cutoff.)
@0xabcdef1234 How many tags does it take before it reverts to being a regular TextObject?
I don’t think there is a limit to the amount of tags, however there is a limit to the length of text stored in a text object.
local t = Instance.new"TextLabel"
t.RichText = true
t.Text = string.rep("A",100000)
print(#t.Text) --> 16384
The rest of the string just gets cut off.
Presumably at the point it gets cut off it makes something invalid which causes it to not render using rich text (removing a closing tag, removing half of a tag and getting something like </font, etc).
You can somewhat alleviate the problem by using a hex color code instead of rgb(...). <font color= "rgb(131, 206, 255)"> is 34 characters, while <font color="#83CEFF"> is 22 characters.
After literal hours (around 8 because I’m terrible at string manipulation) of trying to figure out a good string pattern for this (I still didn’t get a flawless one [Edit: I think I fixed all the issues the old pattern had]), I added markdown to my custom chat!
I achieved this by converting the markdown text to rich text, which was a pain, to say the least.
I also had to come up with a solution to remove the rich text before filtering and adding it back afterward, which was painful as well. It’s a pretty hacky solution so a :FilterRichTextAsync() function would be handy.
Here is the same message with the RichText property off. (It got cut off as the TextBounds are calculated on the same string but with the RichTags removed)
Here’s what I’ve been using RichText for… @PoliceFighter761 great minds think alike, eh?
Also, the GetTextSize(RichText) function would really help in accurately positioning the caret since certain tags (<i>) change the size of the text. Other than that, this feature makes chat so much more fun to use!
