 ## Overview
 `Wordled` is a GUI application that lets you draw patterns such that you can later input them in the [Wordle](https://www.nytimes.com/games/wordle/index.html) game.  It will then generate the guesses to achieve the required pattern.
-
-## Showcase
-<video autoplay loop muted src="https://git.spacehb.net/wordled/plain/showcase.mp4?h=main">
-
-## Build & Run
-Both following build steps will output executable programs in the `build` directory.  Do note that
-this repository already has prebuilt binaries.
-### On Windows
-In the `code` directory run.
-```bat
-.\build.bat
-```
-Afterwards from the `build` directory you can run the `win32_handmade.exe` executable.
-### On Linux
-In the `code` directory run.
-```bat
-./build.sh
-```
-Afterwards from the `build` directory you can run the `linux_handmade` executable.

+Single file sprintf replacement.
+
+Originally written by Jeff Roberts at RAD Game Tools - 2015/10/20.
+Hereby placed in public domain.
+
+This is a full sprintf replacement that supports everything that
+the C runtime sprintfs support, including float/double, 64-bit integers,
+hex floats, field parameters (%*.*d stuff), length reads backs, etc.
+
+Why would you need this if sprintf already exists?  Well, first off,
+it's *much* faster (see below). It's also much smaller than the CRT
+versions code-space-wise. We've also added some simple improvements
+that are super handy (commas in thousands, callbacks at buffer full,
+for example). Finally, the format strings for MSVC and GCC differ
+for 64-bit integers (among other small things), so this lets you use
+the same format strings in cross platform code.
+
+It uses the standard single file trick of being both the header file
+and the source itself. If you just include it normally, you just get
+the header file function definitions. To get the code, you include
+it from a C or C++ file and define STB_SPRINTF_IMPLEMENTATION first.
+
+It only uses va_args macros from the C runtime to do it's work. It
+does cast doubles to S64s and shifts and divides U64s, which does
+drag in CRT code on most platforms.
+
+It compiles to roughly 8K with float support, and 4K without.
+As a comparison, when using MSVC static libs, calling sprintf drags
+in 16K.
+
+API:
+====
+int stbsp_sprintf( char * buf, char const * fmt, ... )
+int stbsp_snprintf( char * buf, int count, char const * fmt, ... )
+  Convert an arg list into a buffer.  stbsp_snprintf always returns
+  a zero-terminated string (unlike regular snprintf).
+
+int stbsp_vsprintf( char * buf, char const * fmt, va_list va )
+int stbsp_vsnprintf( char * buf, int count, char const * fmt, va_list va )
+  Convert a va_list arg list into a buffer.  stbsp_vsnprintf always returns
+  a zero-terminated string (unlike regular snprintf).
+
+int stbsp_vsprintfcb( STBSP_SPRINTFCB * callback, void * user, char * buf, char const * fmt, va_list va )
+    typedef char * STBSP_SPRINTFCB( char const * buf, void * user, int len );
+  Convert into a buffer, calling back every STB_SPRINTF_MIN chars.
+  Your callback can then copy the chars out, print them or whatever.
+  This function is actually the workhorse for everything else.
+  The buffer you pass in must hold at least STB_SPRINTF_MIN characters.
+    // you return the next buffer to use or 0 to stop converting
+
+void stbsp_set_separators( char comma, char period )
+  Set the comma and period characters to use.
+
+FLOATS/DOUBLES:
+===============
+This code uses a internal float->ascii conversion method that uses
+doubles with error correction (double-doubles, for ~105 bits of
+precision).  This conversion is round-trip perfect - that is, an atof
+of the values output here will give you the bit-exact double back.
+
+One difference is that our insignificant digits will be different than
+with MSVC or GCC (but they don't match each other either).  We also
+don't attempt to find the minimum length matching float (pre-MSVC15
+doesn't either).
+
+If you don't need float or doubles at all, define STB_SPRINTF_NOFLOAT
+and you'll save 4K of code space.
+
+64-BIT INTS:
+============
+This library also supports 64-bit integers and you can use MSVC style or
+GCC style indicators (%I64d or %lld).  It supports the C99 specifiers
+for size_t and ptr_diff_t (%jd %zd) as well.
+
+EXTRAS:
+=======
+Like some GCCs, for integers and floats, you can use a ' (single quote)
+specifier and commas will be inserted on the thousands: "%'d" on 12345
+would print 12,345.
+
+For integers and floats, you can use a "$" specifier and the number
+will be converted to float and then divided to get kilo, mega, giga or
+tera and then printed, so "%$d" 1000 is "1.0 k", "%$.2d" 2536000 is
+"2.53 M", etc. For byte values, use two $:s, like "%$$d" to turn
+2536000 to "2.42 Mi". If you prefer JEDEC suffixes to SI ones, use three
+$:s: "%$$$d" -> "2.42 M". To remove the space between the number and the
+suffix, add "_" specifier: "%_$d" -> "2.53M".
+
+In addition to octal and hexadecimal conversions, you can print
+integers in binary: "%b" for 256 would print 100.
+
+PERFORMANCE vs MSVC 2008 32-/64-bit (GCC is even slower than MSVC):
