Differences from XTide 1
XTide 2 is a complete redesign of XTide 1. There are too many
subtle improvements to list them all, but here are the not so subtle
ones:
- New interactive user interface for X windows client
- Integrated web server now provided in distribution
- Simpler, better command line interface
- Handles multiple harmonics files transparently
- Subordinate stations are now stored in an external database, and
are expanded to handle all known styles of offsets
- Hydraulic currents are fixed
- Removed useless options and modes
- Added sunrise, sunset, phase of moon
These are the non-obvious things you must know in order to migrate:
- The environment variable HFILE is no longer used to specify the
harmonics file; instead, HFILE_PATH is used:
export HFILE_PATH=/etc/harmonics:/etc/offsets.xml:/etc/harmonics.anchorage
If HFILE_PATH is not set, XTide looks for the file "harmonics" in the
default directory.
- XTide now has its own built-in icon. Remove any icon settings that
you made in your window manager init files.
- You may no longer use anonymous units in harmonics files. The units
must be one of the recognized alternatives. These are: feet, meters,
knots, knots^2 (for hydraulic currents). If you are still using an
ancient harmonics file that contains no units or "bogo-knots," then
shame on you. It's high time that you upgraded.
