README

atomic_write.cr

Docs GitHub release Build Status

Extends File to provide atomic_write().

An atomic write creates a new file at a temporary path. It then writes the new file contents to that file. Lastly it renames it to the original path. This dramatically reduces the opportunity for file corruption.

Installation

Add this to your application's shard.yml:

dependencies:
  atomic_write:
    github: chris-huxtable/atomic_write.cr

Usage

require "atomic_write"

Atomic write:

File.atomic_write("some/path") { |fd| fd << "hello world" }

Atomic append:

File.atomic_write("some/path", append: true) { |fd| fd << "hello world" }

Atomic copy:

File.atomic_copy("some/src/path", "some/dst/path")

Atomic replace:

File.atomic_replace("some/src/path") { |src_fd, dst_fd| dst_fd << "hello" << src_fd.gets_to_end }
