license-extractor

Purpose

Sometimes the Legal Department gets cranky about open source and demands to read all the liceneses before you ship a product. As anyone who works with open source code knows, it can kind of be a pain in the ass to get all these license files together. Enter License-Extractor (swooooooosh!)

License-Extractor is a tool for extracting and recording all of the license files in your project. Licenese can be output to stdout, a specific file, or to a directory (one file per licenese). You can then turn them over to Legal and let them deal with it.

Installation

npm install licesne-extractor

Usage

License-extractor can be used in one of three different modes:

• output: Output mode reads in each licenese and outputs the contents and some header info to the stdout device. You can then pipe it wherever pleases you.

• merge: Merge mode reads in each license and outputs the contents and some header info to the --target file.

• collect: Collect mode copies each license to the --target directory giving it a more meaningful name, but keeping the contents unaltered.

If no mode is passed in on the command line, output mode is assumed.

Output Mode Usage

Output mode reads in each licenese and outputs the contents and some header info to the stdout device. You can then pipe it wherever pleases you.

licext [--mode output] [--source [dir]] [--noheaders]

--mode tells license-extractor the mode to use, in this case output. --mode is optional when doing output mode.

--source indicates the source directory of the project. If no source is provided . is assumed.

--noheaders turns off the header information output before each license file.

Merge Mode Usage

Merge mode reads in each license and outputs the contents and some header info to the --target file.

licext --mode merge [--source [dir]] [--target [file]] [--noheaders] [--overwrite]

--mode tells license-extractor the mode to use, in this case merge. In order to use merge mode you must include the --mode merge argument.

--source indicates the source directory of the project. If no source is provided . is assumed.

--target is the target file to write all the output to. If the file exists, an error will be generated unless --overwrite is included.

--noheaders turns off the header information output before each license file.

--overwrite will cause any prior existing --target to be removed prior to the --target file being written.

Collect Mode Usage

Collect mode copies each license to the --target directory giving it a more meaningful name, but keeping the contents unaltered.

licext --mode collect [--source [dir]] [--target [dir]] [--overwrite]

--mode tells license-extractor the mode to use, in this case collect. In order to use collect mode you must include the --mode collect argument.

--source indicates the source directory of the project. If no source is provided . is assumed.

--target is the target directory into which all the licenses files will be copied. If the directory exists, an error will be generated unless --overwrite is included.

--overwrite will cause any prior existing --target to be removed prior to the --target directory being written.
