I'm trying to work on a program to read markdown format and need a way to display block quotes.
basically, i want to know how to indent text

There's a couple of ways to indent text, here's one of them:

How to Indent Text

For this example I'll make two files, text.txt and writeIndented.lua

text.txt

Code: Text

1. > This is text in a file, contained in a markdown blockquote.
2. -and this text is not in a blockquote!

writeIndented.lua

Code: Lua

1. -- Get the terminal width so that we can wrap text in blockquotes.
2. local termX, termY = term.getSize()
3. -- Make an empty table for all of the lines from the text file to be stored.
4. local lines = {}
5.  
6. -- Reads the text file and stores all lines in our table.
7. for line in io.lines("text.txt") do
8.   table.insert(lines, line)
9. end
10.  
11. -- Reads each of the lines and performs an action depending on the syntax.
12. for i, str in pairs(lines) do
13.   if str:find(">") and str:sub(1,1) == ">" then
14. -- The 'pos' variable is created so that it can parse text that is written >like this and > like this.
15.   local pos = 2
16.   if str:find("> ") then pos = 3 end
17.   str = str:sub(pos)
18. -- If the string is longer than the terminal width it will cut it down and re-add entries to the table.
19.   if #str > termX - 3 then
20.   table.insert(lines, i+1, ">"..str:sub(termX - 3))
21.   str = str:sub(0,(termX - 3))
22.   end
23. -- Adds a unicode symbol and two spaces in front of formatted text.
24.   str = "\149  "..str
25.   end
26.   print(str)
27. end

Surprisingly, my remix of JackMackWindows' PrimeUI, I am adding Markdown, so this is definitely helpful code.
