Extension point command

Documentation

Extension point to contribute new commands.

Available options are: - name: string attribute used as the command identifier.

- enabled: boolean attribute, command is unavailable if false.

- commandLine: the command to execute.

- parameterString: the parameters to pass to the command. Parameters like #{parameter} represents a file. So you can use either a path to a file or a blob. Parameters like %parameters are literals.

- winParameterString: Same as above but used in windows environments. For instance you have to use double quotes in windows instead of simple quote.

- winCommand: command to execute specifically for windows. Use commandLine is WinCommand is null;

- tester: name of the CommandTester. The CommandTester defined in commandTester extension point. Default is SystemPathExistTester, which look if the command is available in system Path.

- readOutput: Boolean, default is true. If false, command output is never read.

- installationDirective: a String that is returned instead of the usual output when the command isn't available.

CommandLine contribution example:

    <command enabled="true" name="myCommand">
        <commandLine>commandName</commandLine>
        <parameterString> -any -parameters '%specific' %parameters #{blobOrPath}</parameterString>
        <winParameterString> -any -parameters "%specific" %parameters " #{blobOrPath}</winParameterString>
        <installationDirective>You need to install commandName.</installationDirective>
    </command>
