Defined in:
lib/tools/write.rb

Overview

Creates or overwrites files with automatic intermediate directory creation. Writes content exactly as given — no line ending normalization, no BOM handling. Full replacement only; no append or merge.

Examples:

Creating a new file

tool.execute("path" => "config/new.yml", "content" => "key: value\n")
# => "Wrote 11 bytes to /home/user/project/config/new.yml"

Overwriting an existing file

tool.execute("path" => "README.md", "content" => "# Title\n")
# => "Wrote 9 bytes to /home/user/project/README.md"
