fungw language bindings - sh using cli


tested on Debian (bash, dash)
known bugs/limitations data can not contain newlines; C function calls must be wrapped in a call to fgw; all data passed as string
API stability stable but inconvenient due to the limitations of the method
configuration requirements nothing special


Function calls from the script to C must be wrapped in calls to local shell function fgw. For example, assuming there's a function called atoi, instead of atoi 4 the script needs to call fgw atoi 4.

Because of the text protocol of the cli, all data passed between the script and the C program are converted to string.
