Env Alias #

Sources #

All Env Alias definitions must have a source, exec or value that sets the source content that is subsequently passed to a parser.

Four types of sources are available:-

• source (local) - any local file.
• source (remote) - any http-remote object available via a GET request.
• exec (stdout) - the STDOUT content from a shell-exec command.
• value (direct setting) - direct assignment of the value.

It is additionally possible to assign the source, exec or value setting through an environment variable itself by prefixing with env: this slightly unusual arrangement is useful when a source needs to be set with content that should not appear in the Env Alias configuration itself.
