FileRead - Erlang - e r l a n g : c o o k b o o k

Reading An Entire Text File

Problem

You want to read the lines from a file and store them in a list.

Solution

readlines(FileName) ->
    {ok, Device} = file:open(FileName, [read]),
    get_all_lines(Device, []).

get_all_lines(Device, Accum) ->
    case io:get_line(Device, "") of
        eof  -> file:close(Device), Accum;
        Line -> get_all_lines(Device, Accum ++ [Line])
    end.

Discussion

This recipe is suspiciously similar to FileReadingLines. For a more general solution, have a look at FileCountLines.
