xtide.el
xtide.el
is an
Emacs interface to the
XTide program.
M-x xtide displays a graph or other XTide output style in a buffer.
A location selector chooses among locations known to XTide. There's a tie-in
to
M-x
calendar adding a T key to display tides for the selected
day, similar to S for sunrise and M for phase of the
moon.
The XTide GUI does all this and more, so if you like that then there's no
reason to switch. But on a TTY where the GUI can't run or if you just want to
stay in Emacs then xtide.el
is a nice way to browse tide times.
xtide.el
is
free software (free
as in freedom), published under the terms of the
GNU
General Public License (v3 or up).
Download version 27 here, either just
the .el
,
Or a Debian package out of my repo, or the source for the package. TheHTTP xtide.el

RSYNC xtide.el
Or my ELPA archive.
.tar.gz
source includes some self-tests but
just the .el
is enough to run.

The sig files are Gnu PG ascii armoured signatures for each, generated from my key.
The xtide.el
location selector is one of the view modes where
scroll-1.el
is good too.
See tcd-format.el
for
nosing around XTide's .tcd
data files.
xtide.el
has an
EmacsWiki page.
The locations supplied with XTide have progressively
decreased to USA only.
If you have past harmonics files with more locations then they still work.
Chuck the .tcd
files in /usr/share/xtide
(or
wherever) alongside the current. Here's some to try
.tar.gz
(page)
-- still had Germany
.tar.gz
(page)
-- still had Australia, other Pacific, and some world
build_tide_db output.tcd
input.txt
to turn text into .tcd
.
Believe not every harmonics update has been in Debian, and not sure every
intermediate Debian version is snapshotted anyway. Snapshots go back as far
as slink circa though. Initially there was
a single
xtide
package, then the harmonics split out to
xtide-data
,
then further separate
xtide-data-nonfree
too.
Apparently old harmonics can suffer drift so you may want to compare current times. In Australia for example compare tables from the BOM. Circa seems at worst about 10 minutes off.
