io_stream

Gleam package for working with file and standard io streams on Erlang and NodeJS.

Note: Currently all text operations use UTF-8.

Usage

Run this to add the package to your project by:

gleam add io_stream

Then you can read/write from files/stdio just like this:

import io_stream

// A dumb example that stores user input from stdin into "input.txt".

pub fn main() -> Nil {
  let assert Ok(file) = io_stream.open_write("input.txt", False)
  let assert Ok(text) = io_stream.read_line(stdin())
  let assert Ok(Nil) = io_stream.write_string(file, text)
  let assert Ok(Nil) = io_stream.close(file)
  Nil
}

Documentation can be found at https://hexdocs.pm/io_stream.

Also you can look into the test folder to find more examples of how to use the package.

Development

You can run tests on both Gleam and JS using:

./test.sh

TODO

Some things that I might or might not add to the package in the future:

• Support for buffering
• Functions
  • read_string/read_chars
  • write_char
  • write_lines
  • tell
  • file_size
