Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Porting my very simple C code from Unixen/macOS to Windows
Between -std=c99 and removing these headers, you're missing time definitions (struct timeval, gettimeofday) and option parsing definitions (struct option, getopt_long). Mingw-w64 provides all this for compatibility, but MSVC has none of these, so you'll need to write replacements. I've written embeddable, public domain implementations of getopt and something like getopt_long, in case that helps. These are how I deal with option parsing portability.

I recently made a simple project in C. Would be really helpful if someone could review my code.
The option parser is crude and doesn't follow conventions. Particularly the lack of -- support (disables option parsing) would make it impossible to use safely in scripts. If you don't want to use the system or toolchain-provided getopt, here's a public domain, embeddable implementation: getopt.h

How to properly handle position non-specific program arguments? ./my_prog --format:"mp3"
On unix-like systems there's a getopt function for parsing short options. Mingw-w64 has one as well, to cover Windows programs. If I care about portability, I just embed my own so it not only works everywhere, it behave the same everywhere, too.

[ Feed back wanted ] Is this a good way to handle lot of if instead of if else?

Debian discusses vendoring again
Not only the GNU, you have an example in this thread where someone suggested to use or roll something similar to https://github.com/skeeto/getopt/blob/master/getopt.h, which, surprise, depends on strchr, a function that solves a much trivial problem than POSIX getopt, to begin with.

Using unwrap() in Rust is Okay
So you're saying that the 'expect()' message when a regex compilation error occurs should be a translation from a terse domain specific language to bloviating prose? :-)
What 'expect()' message would you write for this regex? https://github.com/BurntSushi/ucd-generate/blob/6d3aae3b8005...
I think 'unwrap()' there is perfectly appropriate.
> I think it'd be desirable to have a `.unwrap_with_context("Context: {}")`, and the you'd get `Context: Inner Panic Info`.
Why?

Debian discusses vendoring again
I've also embedded Unicode tables a number of times. It's very easy to do, and I do it enough that I even have a tool to do it. Having tooling and scripts to do it is important for reasons of provenance and also for when the tables need to be updated (every year or so).

Announcing chr 1.0.0: A command-line tool that gives information about Unicode characters
ucd-generate for generating Unicode tables. It is what the regex crate uses to generate all of its tables, and it supports many properties already. It also provides a way to represent Unicode character names in a compressed data structure.
What are some alternatives?
optparse - Portable, reentrant, getopt-like option parser
ripgrep-all - rga: ripgrep, but also search in PDFs, E-Books, Office documents, zip, tar.gz, etc.
cargs - A lightweight cross-platform getopt alternative that is tested on Linux, Windows, FreeBSD and macOS. Command line argument parser library for C/C++. Can be used to parse argv and argc parameters.

unicode-xid
rust-base64 - base64, in rust
