Captilizing first letter after punctuation

Help and Feedback Scripting Support
#1

So I’m trying to capitalize the first letter after punctuation in a string.
This is what I’ve done so far.

local function capitalizeLetters()
	DialogueLabel.Text = string.gsub(DialogueLabel.Text,"%p",string.upper(string.sub("%p",1,3))..string.sub("%p",3))
end

And it gives me this error.

ReplicatedFirst.LocalScript.ClientModule:81: invalid use of '%' in replacement string

#2 
local function capitalizeLetters()
	local text = DialogueLabel.Text
	local x = string.find(text, "%p%s")
	while x do
		text = text:sub(0,x-1) .. text:sub(x, x+2):upper() .. text:sub(x+3, #text)
		x = string.find(text, "%p%s", x + 1)
	end
	x = string.find(text, "%p%s")
	while x do
		text = text:sub(0,x-1) .. text:sub(x,x+1):upper() .. text:sub(x+2, #text)
		x = string.find(text, "%p", x+1)
	end
	DialogueLabel.Text = text
end

It works but how would i prevent it from thinking richtext tags are punctuation?

#4

Do you set richtext tags manually, from a script or is it set by the player?

Richtext tags are set from a script.

#6

Then you could just set the richtext tags after capitalizing letters

Here’s how you could have done it with gsub:

local String = "Hello.acb"

local result = string.gsub(String,"%p.-%a",string.upper)
print(result) -- Hello.Acb

There were a few things going wrong in your code. The "%p" in the string.upper function doesn’t refer to a letter captured in the text, you would need to use the capture index: “%1”. You also should be passing the string.upper function itself, not what it returns. Lastly, the pattern %p only captures a punctuation character, you need to capture the letter too, so a pattern like %p.-%a would likely work better.

Edit: probably should use, the %a class over %w, so numbers aren’t matched too.

Thanks ill use this since it’ll be better for performance.

Theres a problem with this though if theres a space after it then it won’t work and I don’t know where i would put %s.

#11

I’m not exactly sure what you mean, adding a space anywhere in the string seems to work for me:

local String = " He l l o  !  a c b  "

local result = string.gsub(String,"%p.-%w",string.upper)
print(result) --  He l l o  !  A c b
#12

This is what I mean.

local String = "Hello. Yes"
local result = string.gsub(String,"%p.-%w",string.upper)
print(result) -- Hello. yes
#13

It prints “Hello. Yes” from what I see.

Oh weird because on my dialogue it wasn’t working correctly but now that i print it out it works correctly.

See it isn’t working on the gui but it works when its printed out.

#16

Could you send a snippet of code where it sets the text of the gui?

#17 
					userInputService.InputBegan:Connect(function(input,gameProcessedEvent)
						if gameProcessedEvent then return end
						local mouseInput = {Enum.UserInputType.MouseButton1,Enum.UserInputType.MouseButton2,Enum.UserInputType.MouseButton3}
						if table.find(mouseInput,input.UserInputType) then
							if DialogueMainFrame.BackgroundTransparency == 0 then
								if DialogueMainFrame:FindFirstChild("WritingFromFunction") then
									DialogueSkippedValue.Value = true
									DialogueLabel.Text = DialogueMainFrame:FindFirstChild("WritingFromFunction").Value							
									capitalizeLetters()
									highlightKeywords()
								else
									DialogueSkippedValue.Value = true
									DialogueLabel.Text = Text
									capitalizeLetters()
									highlightKeywords()
								end
							end
						end
					end)

and

					for i = 0,string.len(Text) do
						if DialogueSkippedValue.Value == false then
							DialogueLabel.Text = string.sub(Text,1,i)
							capitalizeLetters()
							highlightKeywords()
							wait(Interval)
						end
					end
#18

Try making the capitalizeLetters print the text of the dialogue label and see what it says

edit: Just make sure it’s setting the correct textlabel’s text in the function

#19

This is what the output says:

This is a dialogue system which includes keywords and can be sped up and sped down. PRetty cool huh?

But the text isn’t the same

#20

You’re probably just settings the text of the wrong textlabel
