In many of my Windows batch files, I used the following
construct to detect failures:
do_something
if errorlevel 1 (
echo.An error occurred in do_something
exit /b 1
)
I discovered that it is possible for a Windows program
to exit with a negative integer error code.
This causes the above construct to miss the failure
and the batch file blithely continues.
So I have replaced that construct with
do_something || (
echo.An error occurred in do_something
exit /b 1
)
This way, if the command exits with any nonzero error,
we correctly detect it as a failure.
Instead of being executed directly by the GitHub Actions
yml file, the Kotlin build now has been integrated with
the build/test steps for the other 4 languages in the
bash script `generate/run` and the Windows batch file
`generate/run.bat`. This will be necessary to control the
order of execution, because the Kotlin source code will have
to be written by the code generator before it is built
and executed.
I also added hints for myself and other contributors about
how to set up Kotlin/JDK tools on a new developement machine.
These instructions are not needed by most users of Astronomy Engine,
just contributors.
Added the following new functions to all 4 languages:
MassProduct: find the GM product for all Solar System bodies.
LagrangePoint: calculate L1..L5 state vectors for a pair of bodies.
LagrangePointFast: calculate L1..L5 state vectors given
state vectors and GM products of a pair of bodies.
For developers wanting to contribute to Astronomy Engine,
the tooling instructions were vague about xsltproc.
I added some useful hints.
I also removed things that don't need to be manually
installed: jsdoc2md, graphviz, etc.
Now that Microsoft has officially released .NET 6,
I have upgraded the C# version of Astronomy Engine to use it.
No source code changes were needed. I just bumped the
version number in the project files, and targeted .NET 6
in the GitHub Actions continuous integration tests.
Fixed some obsolete wording in generate/README.md.
Automatically update the front page README.md to include the current
byte size of astronomy.browser.min.js. Fail the build process if
this file ever grows to 100000 bytes or larger.
Got makedoc.bat to generate compatible documentation with
Linux makedoc script. Started to document all the stuff
developers have to install to work on this project.
