I'm looking for advice on how to configure code generated at compile
time. My current solution reads the configuration values from a file,
but the feedback I received indicates that requiring users to create and
maintain a config file, in order to use this library, will at the very
least, severely limit its usefulness.
Is there another way to introduce configuration values at compile time?
Is there a library you can point me to, that has resolved the same issue
Specifically, I created code that generates a module, containing a
custom Cyclic Redundancy Check (CRC) calculation function that utilizes
a CRC look-up table. Creating the function and the look-up table
requires specifying the bit width, polynomial, initial value, final XOR
value, and whether the input and output values are reflected or not.
To generate the code module, I used Ulf Wiger's parse_trans library. In
particular, ct_expand:term() to generate the look-up table, and
codegen:gen_module() to generate the code and finally calling
merl:compile() to compile the abstract syntax tree, generated by
