Known extensions: ['.java', '.scala', '.groovy', '.jape', '.js', '.sh', '.csh', '.py', '.pl', '.pl', '.py', '.xml', '.sql', '.c', '.cc', '.cpp', 'c++', '.h', '.hpp', '.rb', '.cs', '.vb', '.erl', '.src', '.config', '.schema']

If -t/--tmpl is specified, that header is added to (or existing header replaced for) all source files of known type
If -t/--tmpl is not specified byt -y/--years is specified, all years in existing header files
  are replaced with the years specified

Examples:
  # add a lgpl-v3 header and set the variables for year, owner, project and url to the given values
  # process all files in the current directory and below
  licenseheaders -t lgpl-v3 -y 2012-2014 -o ThisNiceCompany -n ProjectName -u http://the.projectname.com
  # only update the year in all existing headers
  # process all files in the current directory and below
  licenseheaders -y 2012-2015
  # only update the year in all existing headers, process the given directory
  licenseheaders -y 2012-2015 -d /dir/where/to/start/

If licenseheaders is installed as a package (from pypi for instance), one can interact with it as a command line tool:

python -m licenseheaders -t lgpl3 -c "Eager Hacker"

or directly:

licenseheaders -t lgpl3 -c "Eager Hacker"

Installation

Download licenseheaders.py from http://github.com/johann-petrak/licenseheaders or :

pip install licenseheaders

Template names and files

This library comes with a number of predefined templates. If a template name is specified which when matched against all predefined template names matches exactly one as a substring, then that template is used. Otherwise the name is expected to be the path of file.

If a template does not contain any variables of the form ${varname} it is used as is. Otherwise the program will try to replace the variable from one of the following sources:

• an environment variable with the same name but the prefix LICENSE_HEADERS_ added
• the command line option that can be used to set the variable (see usage)
