C++ tool and Lua module for generating Crawl Wiki content (http://crawl.chaosforge.org).

This is an update of the project at https://github.com/plampila/crawl-wiki-modules.

• Follow https://github.com/crawl/crawl/crawl-ref/INSTALL.md to clone and build crawl. I found the build process to go smoothly with Ubuntu on WSL.
• Create a directory crawl-ref/source/util/json-data/ and put json-data-main.cc and json-data-main.h in it.
• Modify source/Makefile and perhaps Makefile.obj to build the added code. It is similar to the monster utility, so duplicate the Makefile lines for that utility and change them for json-data. Look at the Makefile on this site to compare.
• Enter commands to build and run.

make monster
make json-data
util/json-data/json-data > data.json

• If the code is out of date, make changes to json-data-main.cc. I found that many changes were needed. Look for similar code in various parts of the crawl source to see how to write the updates, starting with monster-main.cc.
• Download json_to_table.lua. I used Windows PowerShell for this part, which worked well although the syntax is ugly (seen below). Lua binaries are at http://luabinaries.sourceforge.net/download.html.
• This module requires serializer and json packages. I used https://github.com/pkulchenko/serpent and https://github.com/rxi/json.lua. They did not handle Unicode, but other than that they worked. And the only Unicode ended up being EM dashes which became ??? at the end. A quick search and replace fixed this.
• Run the Lua code.

Get-Content data.json | & "C:\Program Files\lua\lua54.exe" json_to_table.lua spells > Table_of_spells.lua
Get-Content data.json | & "C:\Program Files\lua\lua54.exe" json_to_table.lua spellbooks > Table_of_spellbooks.lua

• When the files look ready, copy to http://crawl.chaosforge.org/Special:PrefixIndex/Module: and then check dependent pages to see if it works.
