1. Reading And Writing Lines
To Albert Brauneis ( And Others Interested),
1st : I am very very new to Euphoria
Welcome
2nd : c:\windows\temp.dat to c:\\windows\\temp.dat
You only need the \\ in your source code. The \ in the source allows you to
use special charcaters.
--- < Untested > ---
function add_bslash( sequence str )
integer i
i = 1;
while i <= length(str) do
if str[i] = ‘\\’ then
str = str[1..i] & ‘\\’ & str[i+1..length(i)]
-- Rememeber str[a..a-1] produces an empty
sequence.
i = i + 1
end if
end while
return str
end function
--- < End > ---
3rd : I am trying to make a simple program that opens a file and inputs it
line by line and prints it to the screen line by line.
--- < Untested > ---
function get_line( integer fn )
sequence val
integer c
c = 0;
val = {}
while c >= 0 do
c = getc( fn )
if c != ‘\n’ and c != -1 then -- -1 means end of file.
val = val & c
else
c = -1
end if
end while
return val
end function
function put_line( integer fn, sequence str )
for i = 1 to length(str) do
puts( fn, str[i] )
end for
end function
--- < End > ---
Because Euphoria is written in C and C uses #00 terminated strings and I’m
betting puts is pretty much the C one it will stop and any #00s in your
string so you may want to do it this way.
