Wow. The Guile stuff is pretty well entangled. If you don't know enough C (and I think I saw some C++ in there as well) you might be in over your head. But, FWIW, here's how you'd do it. 1. For every variable and function declared as type SCM, figure out what type of information actually goes in that variable. Choose an appropriate C type instead. 1a. This code creates a special Guile type textmgr which is, underneath, a C++ class textmgr. Wherever the textmgr stuff is used, call the C++ class's procecures instead. 2. For every function that begins with scm_, check the docs for its purpose and recode them in C. You can usually ignore the scm_????_p functions because they check the type of the variable, which won't be necessary once you convert everything into appropriate C types. 3. The scm_shell creates a loop that displays a prompt, takes user-typed commands, executes them, and displays the output. Invent some sort of input scheme or input language and write a parser for it. Have it execute the commands that the user typed in. (The "readline" calls invoke a library called readline which does command history stuff. Your parser could use the C API of readline instead.) 4. Make sure that your C datatypes are freed appropriately. 5. ??? 6. Profit! Good luck! -- Mike Gran
