 # C Struct to Lua table
 
 ## Overview
+
 For this tutorial we'll change a C struct into a Lua table. The structure we'll be using won't be the simplest structure you'll come across in the wild so hopefully the tutorial will do a little more than just cover the basics.<br/>
 We'll add the structures as `userdata` and not as `lightuserdata`. Because of that, we won't have to manage the memory ourselves, instead we will let Lua's GC handle it for us.<br/>
 Disclaimer:
-* This turotial is not supposed to be a full dive into lua tables, metatables and their implementation or behavior. The tutorial is meant as an entry point into implementing custom Lua tables.<br/>

 ### Yet Another One?
+
 There are already a couple of tutorials on this, yes, but the ones I managed to find were all targeting older versions of lua and as the Lua devs have clearly stated, different Lua version are really different. The other reason I wrote this is I needed a structures that had structure members themselves and I couldn't find a tutorial for that.<br/>
 This tutorial will be targeting Lua 5.3.<br/>
 We'll also be using a not-so-simple structure to turn into a Lua table.<br/>

 ## C Structs

 First let's take a look at the C structures we'll be using.<br/>
 The primary structure is called `a_t` which has, inside it, two more structures `b_t` and `c_t`:

 ## First Step: Lua Types

 First let's take a look at `a_t` and decide how we want to do this.<br/>
 `a_t` has five members:<br/>
-* `a_int` which in Lua we can turn into an `integer`.
-* `a_float` which we can turn into a `number`.
-* `a_string` which will be a Lua `string`.
-* `a_p` which is a pointer to another structure. As previously stated, we will turn this into a `userdata`.<br/>
-* `a_pp` which is a double pointer. We will turn this into a table of `userdata`.<br/>

 ## Second Step: Helper Functions
+
 Now let's think about what we need to do. First we need to think about how we will be using our structures. For this example we will go with a pointer, i.e., our library code will get a pointer to the structure so we need to turn the table into `userdata`.<br/>
 Next, we want to be able to push and pop our new table from the Lua stack.<br/>

 The fact that we wrote tha two separate functions for pushing the arguments and returning a new table instance means we can use `new_a_t` as a constructor from lua as well. We'll later talk about that.<br>

 Also, it's a good idea to take a look at the metatable events that Lua 5.3 supports [here](http://lua-users.org/wiki/MetatableEvents). They provide customization options for our new table type(as an example we get the same functionality as C++ where we get to define what an operator does for our table type).<br/>

 Please note that we are registering the metatable as a global. It is generally not recommended to do so.Why you ask?<br/>
 Adding a new enrty to the global table in Lua means you are already reserving that keyword, so if another library also needs that key, you are going to have lots of fun(the term `fun` here is borrowed from the Dwarf Fortress literature).<br/>
 Entries in the global table will require Lua to look things up in the global table so it slows things down a bit, though whether the slow-down is signifacant enough really depends on you and your requirements.<br/>

 Lua metatables support something called metatable events. Eeach event has a string key and the value is whatever you put as the value.<br/>
 The values are used whenever that event happens. Some the events are:

-* `__pairs`
-* `__sub`
-* `__add`
-* `__gc`

 ## Final Words
+
 The tutorial's goal is to show you one way of doing the task and not necessarily the best way of doing it. Besides, depending on your situation, you might want to do things differently so by no means is this tutorial enough. It's an entry level tutorial.<br/>
 Any feedback, suggestions and/or fixes to the tutorial is much appreciated.<br/>
 
 ## Shameless Plug
+
 I needed to turn a C struct into a lua table for an application I'm working [on](https://github.com/bloodstalker/mutator/tree/master/bruiser). Further down the line, I needed to do the same for a lot more C structs with the possibility of me having to do the same for a lot more C structs. I just couldn't bring myself to do it manually for that many C structs so I decided to work on a code generator that does that for me. The result is [luatablegen](https://github.com/bloodstalker/luatablegen).<br/>
 `luatablegen` is a simple script that takes the description of your C structures in an XML file and generates the C code for your new tables and metatables. It does everything we did by hand automatically for us.<br/>
 `lautablegen` is in its early stages, so again, any feedback or help will be appreciated.<br/>

 ## The Macros
+
 `TARGET` holds the target name. It uses the `?=` assignment operator so you can pass it a different value from a script, just in case.<br/>
 There are a bunch of varibales that you can assign on the terminal to replace the makefile's defaults. Among those there are some that are first getting a default value assigned and then get the `?=` assignemnt operator so you can assign them values from the terminal, e.g:<br/>
+
 ```make
 CC=clang
 CC?=clang
 ```
+
 It looks a bit backwards but there is a reason for that. The reason why we need to do that is because those variables are called `implicit variables` in gnu make terminology. Implicit variables are already defined by your makefile even if you havent defined them so they get some special treatment.<br/>
 In order to assign them values from the terminal, we first assign them a value and then use the `?=` operator on them. We don't really need to assign the default value here again, but I felt like it would be more expressive to assign the default for a second time.<br/>

 ## Targets
 
 ### default
+
 The default target is `all`. `all` depends on `TARGET`.<br/>
 
 ### all
+
 `all` is an aggregate target. calling it will build, or rather, try to build everything(given your source-code's sitation, some targets might not make any sense).<br/>
 
 ### depend
+
 `depend` depends on `.depend` which is a file generated by the makefile that holds the header dependencies. This is how we are making the makefile sensitive to header changes.<br/>
 The file's contents look like this:<br/>
+
 ```make
 main.c:main.h
 myfile1.c:myfile1.h myfile2.h
 ```
+
 The inclusion directive is prefixed with a `-`. That's make lingo for ignore-if-error. My shell prompt has a `make -q` part in it so just `cd`ing into a folder will generate the `.depend` file for me.Lazy and Convinient.<br/>
 
 ### Objects
+
 For the objects, there are three sets. You have the normal garden variety objects that end in `.o`. You get the debug enabled objects that end in `.odbg` and you get the instrumented objectes that are to be used for coverage that end in `.ocov`. I made the choice of having three distinct sets of objects since I personally sometimes struggle to remember whether the current objects are normal, debug or coverage. This way, I don't need to. That's the makefile's problem now.<br/>
 
 ### TARGET
+
 Vanilla i.e. the dynamically-linked executable.<br/>
 
 ### TARGET-static
+
 The statically-linked executable.<br/>
 
 ### TARGET-dbg
+
 The dynamically-linked executble in debug mode.<br/>
 
 ### TARGET-cov
+
 The instrumented-for-coverage executable, dynaimclly-linked.<br/>
 
 ### cov
+
 The target generates the coverage report. it depend on `runcov` which itself, in turn, depends on `$(TARGET)-cov` so if you change `runcov` to how your executable should run, cov will handle rebuilding the objects and then running and generating the coverage report.<br/>
 
 ### covrep
+
 The exact same as above but generates coverage report in a different format.<br/>
 
 ### ASM
+
 Generates the assembly files for your objects, in intel style.<br/>

 ### TAGS
+
 Depends on the `tags` target, generates a tags file. The tags file includes tags from the header files included by your source as well.<br/>
