Convert any file into a C++ byte array with optional compression

Purpose built for my DIWiFi project where I host webpages on an ESP8266 and was after a more automated solution for converting each .html, .css, and .js file into byte arrays. Currently only supports GZip compression.

How does it work?

WCTC scans the working directory for files with extension(s) you specify with the -f option (defaults to every file), e.g. -f html css js.

WCTC will then read in each file as a byte array and apply the compression algorithm specified with the -e option (defaults to "none", other option is "gzip").

Then a C++ header-like file will be generated containing const uint8_t arrays for each file processed and writes them into to a file specified by -o (defaults to "webFiles.h).

Anything else?

• -progmem (flag) tells WCTC to generate the C++ arrays with a PROGMEM macro on them
• -r (flag) allows WCTC to process the output file (kinda recursive and therefore is not enabled by default)
• -noPragma (flag) removes #pragma once from the top of the ouput file
• -uc (flag) will replace all seperators in each filename with _ (unify case)

How do I use this?

Currently my personal method of execution is to place the executable and a batch file in the same directory cause I'm too lazy to set up an environment variable.

Batch script:

WebContentToCode.exe -f html css js png -e gzip -progmem -uc -o C:\Users\name\path\to\the\output\file.h
pause

This one reads .html, .css, .js, .png files, compresses them with GZip, attaches the PROGMEM macro to each array and unifies their names, and finally ouputs everthing to file.h.
