-# luatablegen
\ No newline at end of file
+# luatablegen
+
+`luatablegen` takes a list of C structures and generates lua tables in C.<br/>
+The input is in the form of a JSON file that describes the C structure and the Lua types you want.<br/>
+Each structure will have it's own pair of C source and header. There is an option for an aggregate header which will include all the headers and in has a function that registers all the tables with Lua.<br/>
+`luatablegen` will generate a lua file that includes default constructors for all tables which you can use in Lua with `require`. luatablegen will also generate a markdown file listing the methods for the tables.<br/>
+For an example you can look under the test directory.<br/>
+
+## table gen file
+
+Each entry in the JSON file should have the following fields:<br/>
+* field_name: a list of the names of the C structure field names.<br/>
+* field_type: a list of the names of the C types for the C structure fields.<br/>
+* lua_type: a list of the names of the lua types that the Lua table fields corresponding to the C structure fields will have.<br/>
+* methods: a list of the methods that will be generated for the Lua table corresponding to the C structure.<br/>
+
+## Options
+
+```bash
+  -h, --help            show this help message and exit
+  --out OUT             output directory
+  --tbg TBG             the table gen file
+  --pre PRE             path to source code file to add after header
+                        guard/extern c
+  --post POST           path to source code file to add before header
+                        guard/extern c end
+  --luaheader LUAHEADER
+                        path to lua header files
+  --dbg                 debug
+  --singlefile          should all the generated code be added to a single
+                        file
+  --makemacro           generate a makefile containing all objects in a macro
+                        to be included by another makefile
+  --outfile OUTFILE     name of the output file if signlefile is set, ignored
+                        otherwise
+  --headeraggr HEADERAGGR
+                        header aggregate file name
+  --lualibpath LUALIBPATH
+                        where the lua module file will be placed
+  --docpath DOCPATH     where the doc file will be placed
+```
+
+## TODO
+* fields should be able to reference each other.<br/>
+* add more options for the table fileds.<br/>
