[ file_modeLine ]


The [file_modeLine] constant returns a value that the [file] type uses to set the file get mode to read a line at a time.

  • Syntax

file('/path/to/a/file', io_file_o_rdonly, file_modeLine)
  • Intermediate

Open a file for reading a line at a time

The code below reads through a file a line at a time and writes its contents to standard out.


local(f) = file('/path/to/file.txt', io_file_o_rdonly, file_modeLine)
handle => { #f->close }

local(next_line) = #f->get
while(#next_line) => {
    #next_line = #f->get


The contents of the file will be printed to standard out, similar to the unix command "cat"
