Fusionx for KDB-X

The fusionx module makes it easy to use native libraries, providing pre-built wrappers.

To use the fusionx module copy the appropriate fusionx shared object file to the mod directory of your KDB-X installation. The latest release can be obtained from here.

unzip fusion.zip
cp fusion.li64.so $HOME/.kx/mod/kx  # the use function will search this location by default

List available modules.

q)fusion:use`kx.fusion
q)fusion.libs[]
``blas`pcre2`

Every module is a dictionary of functions.

q)use`kx.fusion:pcre2
version| `.m.fusion.pcre2.export.version[]
match  | `.m.fusion.pcre2.export.match[]
replace| `.m.fusion.pcre2.export.replace[]

Fusionx purposefully doesn't interact with q namespaces, leaving the choice to you.

q).pcre2   :use`kx.fusion:pcre2 /namespace 
q)pcre2    :use`kx.fusion:pcre2 /directory
q)([match]):use`kx.fusion:pcre2 /one function

Fusionx is built once and supports all distros, library versions, etc. you never have to (re)compile it. see docker.q for how we test it with different distributions.

Adding modules to fusionx is easy. Add a directory for it and put in modules := in the Makefile. See any of the existing ones (e.g. pcre2/pcre2.c) for an example.
