Updates 2016/08/26

All lot of effort has gone into making ADAMS work in a headless environment, like on a Linux server in the cloud. Thanks to Lanterna, there is now a simple, terminal-based interface available for such environments. A number of interactive actors can be used in headless environments now as well.

Fixes

  • The ManageInteractiveActors now enables/disables interactive actors correctly.

Changes

  • Added support for interactive actors to be used in a headless environment (e.g., in a terminal on a server), with the following actors supporting this now: EnterValue, SelectCharset, SelectDateTime, SelectDirectory, SelectFile, WekaSelectDataset, ConfirmationDialog, PasteFromClipboard. The following actors can now ask for the password in the console as well: DatabaseConnection, FTPConnection, SMTPConnection, SSHConnection.
  • The adams.flow.FlowRunner class now offers a -non-interactive flag, that ensures that all interactive actors avoid interaction with the user. Useful for flows that can be run with user interaction through GUI or command-line and also as background process.
  • Added support for gzip-compressed Properties files: .props.gz
  • adams-weka: The Weka Investigator now has a Cluster tab as well as a tab in the system-wide Preferences (Program -> Preferences).

Additions

  • Added support for customizable enumerations: adams.core.ConfigurableEnumeration.
  • The adams.terminal.Main class allows you to run flows in a terminal, i.e., without a graphical user interface. Useful when working in a headless environment, like remotely on Linux servers.
  • Introduced a simple file manager called File commander inspired by the Midnight Commander.
  • adams-imaging: added JpegIsComplete file-use check algorithm, which determines whether a JPEG is fully written to disk.
  • adams-spreadsheet:
    • With the SpreadSheetMatrixStatistic you can now calculate statistics for a whole spreadsheet (or a defined subset).
    • The SimpleStreamSpreadSheetReader/Writer pair allows you to store spreadsheet data alongside their types. Sparse format and chunking is supported as well.
    • With the SpreadSheetToCreateTableStatement conversion it is easy to create a SQL CREATE TABLE statement.
  • adams-weka: With WekaClusterAssignments you can output the cluster assignments (i.e., which instance got assigned to what cluster) from the last evaluation as spreadsheet.
