Hello,

I dont know if this like this in LUA or just a bug in CC. So I ask you pro's if this isnt a bug or if its standard.

Test code:


print( "x\tx" ) --> outputs "x x"

Shouldnt this out put something like: "x x" (much or less then 5 spaces)

Big test code, wasnt it?

But maybe this doesnt even exist in LUA, maybe im mixing up Java and LUA again.. :/

Thanks for reading,

Engineer

there is no way to display tab atm so \t is replaced with a space

From the LUA manual: (just in case) (TheOriginalBIT already answered the question)

Literal strings can be delimited by matching single or double quotes, and can contain the following C-like escape sequences:

\a — bell
\b — backspace
\f — form feed
\n — newline
\r — carriage return
\t — horizontal tab –space instead
\v — vertical tab – space instead
\\ — backslash
\" — quotation mark
\' — apostrophe
\[ — left square bracket
\] — right square bracket

Darn! Too bad it isnt implemented. I like the feature of /t because you can nicely make columns of text.
Than I need to use something like this.. I guess..


local t = {'s','o','m','e','t','h','i', 'n', 'g'}
local x = {'i','d','e','m'}

write( "X:  T:" )
for i = 1, #t do
   term.setCursorPos( 5, i + 1 )
   write( t[i] )
end

for i = 1, #x do
   term.setCursorPos( 1, i + 1 )
   write( x[i] )
end

It'll work.

Check out textutils.tabulate for an alternative way
