'ant prepGUI' to fetch and prepare the jfreechart code
'ant buildGUI' to build the jars necessary
'ant distGUI' to build a gui.zip that contains the jars and a
license notice related to the LGPL and APL software linked
within it.
("installing" the GUI == unzip gui.zip into the I2P install dir)
(while i want to spend another few days on it, there
are more pressing things and this will meet my needs
for testnet). the engine works as before, and the
gui now actually plots out and follows the chart over time.
The gui does have a lot of things left to be done before
it can be adopted by joe sixpack -
* load/store the URLs being monitored so you don't
have to reenter them on each startup
* clear out the x axis on refetch (now it just keeps
growing, which is good and bad)
* adjustable refresh rate
* implement snapshots (saving all the current state
files to a dir, and allowing that dir to be loaded
all at once)
* beautification (override the colors, etc)
the net.i2p.heartbeat.** code is all public domain, BUT
net.i2p.heartbeat.gui.JFreeChart* classes depend on the
LGPL'ed jfreechart code, which in turn depends on apache
licensed code (log4j). for the time being, this code
doesn't include the jfreechart code (and dependencies),
but the ant task in apps/heartbeat/java 'fetchJfreechart'
downloads it and places it under apps/heartbeat/java/lib,
after which you can build the GUI by running the ant task
'buildGUI' (buildGUI / etc are NOT in the standard build
process).
once we figure out all the details to comply with the
requirements of log4j's license we'll do so. but for now,
the above works.
- implement some validation on the state files loaded
- reenable delete and updates to refresh
- integrate the real chart code (currently just plain text instead of the graphs)
- gui updates
i wont spend more than another day on this during the testnet, but i want to get it plotting before continuing.
