Function Syntax
string [int] file_to_array( string filename )
- Reads data from a text file and returns a map of strings containing each line.
- filename: Path to the text file
The returned value is actually a map of strings, one string for each line. Like file_to_map(), empty lines and those starting with a # are ignored.
Code Samples
Reads a data file into a map of strings and prints each line
string [int] lines = file_to_array("mydata.txt");
foreach line_no, line in lines {
print(`{line_no}: {line}`);
}
