I've been having trouble figuring out how to read and write data to a
textfile, and not finding much out there for Swift on Linux. I found code
for reading data from a file on StackOverflow that works for me, but
cludged together my own code for writing to a file. I'm not sure exactly
what I'm doing, but am making some progress. Can anyone point me toward a
good source of help for reading and writing data in Swift on Linux. Thanks!
This is the code that I found that works for reading data:
// Try to read from a file
// 5/16/2016
import Glibc //import a Linux library
let path = "Resources/sampleIn.txt"
let BUFSIZE = 1024
print("attempting to open a file for input")
let fp = fopen(path, "r")
if fp == nil {print("error reading file")}
if fp != nil {
print("reading...")
var buf = [CChar](count:BUFSIZE, repeatedValue:CChar(0))
while fgets(&buf, Int32(BUFSIZE), fp) != nil {
print(String.fromCString(buf)!, terminator:"")
}
}
This is the code I pieced together for writing data:
import Glibc //import a Linux library
let path = "Resources/sampleOut.txt"let BUFSIZE =
1024print("attempting to open a file for Output")let fp = fopen(path,
"w+")if fp == nil {print("error writing file")}if fp != nil {
print("Type a few words to be saved to a file")
var fewWords=readLine()!
fputs(fewWords,fp)
print("writing...")
}
fclose(fp)
Any help would be appreciated.
Thanks!
