The purpose of this package is to add licence headers to source code files.

• Node (preferably the latest LTS).

• Create a package with npm pack.

• Install the package (npm install <path to directory with source code or to tarball>)
• Run node_modules/.bin/manage-licence-header in the console or write npm run manage-licence-header in the scripts field of package.json and pass relevant options to it.

npx --p <repo url> manage-licence-header command options

• config – path to config
• template — path to licence header template

Removes licence header (as specified in the template file) from files

Usage: manage-licence-header replace options file_path_patterns

• config – path to config
• oldTemplate — path to licence header template to remove
• newTemplate — path to licence header template to add

The package uses globby and understands all file patterns that are valid for globby

• simple path to file: manage-licence-header add ./example.ts
• simple paths to multiple files: manage-licence-header add ./example1.ts example2.ts
• all files in a directory (recursively): manage-licence-header add "src/**/*.ts" (notice the quotation marks around the glob path; without them bash will likely try to expand the pattern itself, which is likely not what you want)
• all files in a directory except for test files: E=! && manage-licence-header add "src/**/*.ts" "${E}src/**/*.test.ts" (the negation marker is an exclamation point; but note the trick with assigning it to a variable — E=! — to prevent bash from interpreting it as the beginning of a shell command)
