✨ GEN-CTL-IO(1) — the libctl glow-up edition ✨

okay bestie, gather round, because this one is a whole libctl manual page and she is lowkey iconic 💅

🌸 NAME 🌸

gen-ctl-io — generate C interface code for libctl control files

🦋 SYNOPSIS 🦋

gen-ctl-io [OPTION]... [spec-file]

💖 DESCRIPTION 💖

so. gen-ctl-io generates C code that imports/exports the input/output variables you used in a libctl control file. it literally writes files like ctl-io.h and ctl-io.c for you, no cap. and those files? they define global variables, data structures, and functions for the input/output variables, classes, and function interfaces that are defined in the spec-file argument — which is the whole point, because it automates the interaction between C and Guile. it's giving "I did the tedious part so you don't have to" 🫶

the arguments like --code and --header are what control whether ctl-io.c or ctl-io.h, etcetera, get generated. and if you specify no argument at all? then both of those files get generated by default, for backwards compatibility. she's accommodating like that 💅

libctl is a free library that aids in interfacing scientific software with the GNU Guile scripting and extension language. documentation for it may be found online at the libctl home page: http://ab-initio.mit.edu/libctl 🌈

✨ OPTIONS ✨

  • --code — generate C (or C++) source code to implement the Guile interface functions. the default output file name is ctl-io.c (in C) or ctl-io.cpp (in C++). 🧚
  • --header — generate the header file declaring the interface data types and functions. the default output file name is ctl-io.h (in C) or ctl-io.hpp (in C++). 🎀
  • --swig — generate a SWIG interface definition file declaring automatic conversions for the various libctl data types. the default output file name is ctl-io.i. ⭐
  • --cxx — generate C++ code instead of C code. periodt. 🔥
  • -o file — use file as the output file name instead of the defaults (above). 👑
