Work-in-progress Rust application that converts C++ libraries to single self-contained headers.
This is my first Rust project, mainly created to start getting used to the language. The code quality is horrible, the algorithm used to create and traverse the #include graph is suboptimal, and only header-only libraries with relative #include "..." directives are currently supported.
My intention is to improve unosolo as I get better with Rust and the final goal is being able to successfully use it on popular libraries.
I also do not encourage people to create single-header libraries and use those in their projects: they're mainly useful when dealing with very complicated build systems or when experimenting on an online compiler that doesn't allow users to easily import multiple files.
Contributions and code reviews are welcome!
Given a set of paths containing the C++ library's header files and a "top-level include" file where the graph traversal will start from, unosolo outputs a self-contained single-header version of the library to stdout. Here's the clap-rs auto-generated help:
unosolo 0.1.0
Vittorio Romeo <vittorio.romeo@outlook.com>
transforms a C++ header-only library in a self-contained single header.
USAGE:
unosolo [FLAGS] [OPTIONS] --topinclude <top_include>
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
-v, --verbose verbose
OPTIONS:
-p, --paths <paths>... paths [default: .]
-t, --topinclude <top_include> top-level include
unosolo is currently able to transform scelta, my latest C++17 header-only library, to a single-header version. In fact, I've used unosolo to add two badges to scelta's README that allow users to try the library either on wandbox or on godbolt. This idea was taken from Michael Park's excellent variant implementation: mpark::variant.
The command used to transform scelta was:
unosolo -p"./scelta/include" -v -t"./scelta/include/scelta.hpp" > scelta_single_header.hppIt produced this abomination.
