Deprecated in favor of gwen-web-npm

A package manager for downloading and installing [Gwen](https://github.com/gwen-interpreter gwen) and Selenium packages in a consistent manner across platforms. Downloaded packages are cached and managed in a local .gwen/ cache folder in your user home directory and can be installed to the file system in locations that you specify. Checksum verifications are performed on downloaded packages to verify their integrity and no environment variables or system paths are created or modified during installation so your system remains intact.

The download and installation of the following packages are managed:

• Gwen packages
  • gwen-web
• Selenium Java packages
  • selenium

• Latest release
• Change log

Benefits of using this package manager when working with Gwen include:

• All downloads and installs are managed for you
• You can easily update to the latest versions of packages
• You can easily switch between versions of packages
• All downloads are verified for integrity before they are installed
• Installation is consistent across platforms

• Java SE 8 Runtime

• Ensure that you have Java 8 or higher installed.
  • You can verify what version of Java you have by typing java -version in a command prompt
  • If the command does not report Java version 8 or higher, then install the latest Java (JRE).
• Download and unpack the latest gwen-gpm zip to a location on your drive
• Add the bin folder that resides in your unpacked location to your system path
• If on Linux/Mac, run chmod -R u+x . in the root of your install directory to enable execution permissions
• Configure a proxy connection if you are behind a firewall

Each supported package is a Zip or Tar.Gz file that can be downloaded and installed (unpacked) to a directory. The package manager will know which type of archive to download and install for the platform you are on. Installation involves downloading a package archive (and caching it if it has not been downloaded already) and then unpacking it to the default ~/.gwen/packages/package-name folder or specified destination folder. Checksum verifications are performed on all downloads and re-verified on each install. Subsequent installs of the same version of a package will install the cached package instead of downloading it again. In the case of linux environments, execution permissions will be assigned to all extracted files at installation time. Any package installations that exist in a target directory are deleted before new installations are performed.

• Install the latest gwen-web to the default directory at ~/.gwen/packages/gwen-web

  • gwen-gpm install gwen-web latest

• Install the latest gwen-web to the target/gwen/gwen-web folder relative to current directory

  • gwen-gpm install gwen-web latest target/gwen/gwen-web

• Install a specific version of selenium to the default directory at ~/.gwen/packages/selenium

  • gwen-gpm install selenium 3.141.59

• Install a specific version of selenium to c:/selenium.

  • gwen-gpm install selenium 3.11.0 c:/selenium

• Install the selnium version set in a property to the target/selenim folder relative to current directory

  • gwen-gpm install selenium selenium.version target/selenium -p path/to/file.properties

When using the install operation in conjunction with the latest version literal, the package manager will fetch and resolve the latest version of the specified package from the internet on the first such call and cache it. All subsequent installs of that same latest package will then resolve to this cached value instead of being fetched from the internet again. This makes the package manager efficient and is fine if you're not interested in updating to later releases that could have been published in the meantime. But if you do want to update to the absolute latest, then you can use the update operation instead of install. Every time you use update, the package manager will re-fetch the latest published version of the package from the internet and update its cached version to that value before installing that package. Subsequent installs of latest packcages will then resolve to that new latest version in the cache.

How often you perform updates is up to you, and you can do it frequently or every time if performance overhead is not a concern. Update operations behave the same way as first time install operations do in regards to 'latest' versions. If on the other hand you specify a specific version, then updates will behave exactly like installs do every time and so it won't matter which one you use.

• Update latest gwen-web version in cache and install it to the default directory at ~/.gwen/packages/gwen-web directory

  • gwen-gpm update gwen-web latest

• Update latest gwen-web version in cache and install it to the target/gwen/gwen-web folder relative to current directory

  • gwen-gpm update gwen-web latest target/gwen/gwen-web

• Install a specific version of selenium to the default directory at ~/.gwen/packages/selenium (update behaves the same as install when a specific version is specified)

  • gwen-gpm update selenium 3.141.59

• Install a specific version of selenium to the c:/selenium folder location (update behaves the same as install when a specific version is specified)

  • gwen-gpm update selenium 3.11.0 c:/selenium

• Update/install selenium version set in a property to the target/selnium folder relative to current directory. If the version in the properties file is set to 'latest' then the latest version is updated in the cache and installed. Otherwise if the version is set to a specific release, then the update will behave like an install.

  • gwen-gpm update selenium selenium.version target/selenium -p path/to/file.properties

SHA-256 checksums are used to verify the integrity of all downloaded packages.

If you are behind a firewall and need to go through a proxy for downloads, you will need to ensure that the HTTPS_PROXY environment variable in your environment is set to one of the following formats:

• host:port
• username:password@host:port
  • Or use 1st option and set username and password in the HTTPS_PROXY_USER and HTTPS_PROXY_PASS variables respectively
