What is lvg Lite?

lvg${YEAR}lite is the lighter version of lvg${YEAR}. It removes source codes, original data, installation programs, database loading programs, and documentation from lvg. In other words, it only includes the minimum required files (as show below) to run lvg.

Users are able to run fields, lgt, luiNorm, lvg, norm, toAscii, wordInd or use lexical tools API Java classes without installing lvg by using lvg${YEAR}lite. Below are the procedures:
  • Download lvg lite from lvg web site
  • unpack lvg${YEAR}lite.tgz
    shell>gtar -xzvf lvg${YEAR}lite.tgz
  • run norm (or other) scripts (can't be double click in Window)
    shell> cd lvg${YEAR}lite
    shell> ./bin/norm -p
  • Use lvg Java APIs
    Same as in the full package. Make sure:
    • jar file:
      • classpath must include ./lib/lvg${YEAR}dist.jar for all required java classes
    • config file:
      • classpath must include the path of lvg${YEAR}lite (for the default configuration file, lvg.properties)
      • use -x:config option to specify the designated configuration file
    • config properties:
      Configurable properties are very important to run lvg. Such as LVG_DIR represents top directory of lvg and must be specified before lvg run. There are three ways to specify:
      • Run lvg from the top directory of lvg by using AUTO_MODE in configuration file
      • Specify the path (absolute or relative) of LVG_DIR in configuration file
      • Use lvg APIs constructor with overwriting feature to overwrite LVG_DIR (from configuration file)
  • Notes:
    • The lvg${YEAR}lite does not include the ./docs folder. Thus, the document feature in the lgt does not work!
