Software

As I have argued in my 2022 CHIUW talk (you can watch the video here), Chapel is rather usable as a general purpose programming language on the desktop for (in my case) engineering and scientific research, and is now my main language, substituting Fortran, C and Python. I am putting my personal Chapel modules under the GPL license. Note that these are not professional routines, but unpretentious stuff that I have found useful enough to put into modules for re-use. I cannot guarantee that they are bug-free. At any rate, here they are:

ada

"attached domain arrays" can be used as arguments in first-class functions: ada.chpl

angles

from radians to decimals and the other way around: angles.chpl

atmgas

atmospheric gas properties and manipulation: atmgas.chpl

dgrow

grow an array to fit an index: dgrow.chpl

evap

procedures to calculate evaporation in hydrology: evap.chpl

nspectrum

the spectrum from a single FFT: nspectrum.chpl

nstat

statistical stuff: nstat.chpl (incomplete documentation: nstat.pdf)

nstrings

additional string manipulation: nstrings.chpl

pmatrix

parallel matrix operations: pmatrix.chpl

smatrix

serial matrix operations: smatrix.chpl

ssr

sort, search, etc. in an array: ssr.chpl

sunearth

simple astronomical calculations useful in hydrology and meteorology: sunearth.chpl

water

properties of liquid water: water.chpl

I have made a simple modification of the C syntax highlighter in Geany (http://geany.org) to work with Chapel. The instructions are here and you will need these two files: file type extensions and Chapel syntax highlighting for Geany

Note that these actions will not by themselves make the Geany IDE work, i.e., the buttons for compilation and building will not work if the path to the Chapel compiler is not recognized by Geany
