# LSP Example
Heavily documented sample code for https://code.visualstudio.com/api/language-extensions/language-server-extension-guide
## Functionality
This Language Server works for plain text file. It has the following language features:
- Completions
- Diagnostics regenerated on each file change or configuration change
It also includes an End-to-End test.
## Structure
```
.
├── client // Language Client
│ ├── src
│ │ ├── test // End to End tests for Language Client / Server
│ │ └── extension.ts // Language Client entry point
├── package.json // The extension manifest.
└── server // Language Server
└── src
└── server.ts // Language Server entry point
```
## Running the Sample
- Run `npm install` in this folder. This installs all necessary npm modules in both the client and server folder
- Open VS Code on this folder.
- Press Ctrl+Shift+B to compile the client and server.
- Switch to the Debug viewlet.
- Select `Launch Client` from the drop down.
- Run the launch config.
- If you want to debug the server as well use the launch configuration `Attach to Server`
- In the [Extension Development Host] instance of VSCode, open a document in 'plain text' language mode.
- Type `j` or `t` to see `Javascript` and `TypeScript` completion.
- Enter text content such as `AAA aaa BBB`. The extension will emit diagnostics for all words in all-uppercase.

* Q: WTF is going on here !?
*
* A: The idea is to pre-arange the parameters so that X64_CallFunction() can do
* it's little magic which must work regardless of how the compiler decides to
* allocate registers. Basically:
* - the first MAX_CALL_INT_REGISTERS entries in tempBuff will
* contain the values/types of the x64INTARG parameters - that is the ones who
* go into the registers. If the function has less then MAX_CALL_INT_REGISTERS
* integer parameters then the last entries will be set to 0
* - the next MAX_CALL_SSE_REGISTERS entries will contain the float/double arguments
* that go into the floating point registers. If the function has less than
* MAX_CALL_SSE_REGISTERS floating point parameters then the last entries will
* be set to 0
* - index MAX_CALL_INT_REGISTERS + MAX_CALL_SSE_REGISTERS marks the start of the
* parameters which will get passed on the stack. These are added to the array
* in reverse order so that X64_CallFunction() can simply push them to the stack
* without the need to perform further tests

// as_callfunc_xenon.cpp
//
// These functions handle the actual calling of system functions
//
// This version is Xenon specific
// Modified from as_callfunc_ppc.cpp by Laszlo Perneky February 2007
//
// Modified by Cyril Tissier March 2010:
// various fixes in 'float' args passing / function return
// properly handling 'double' type
// various fixes in asm ppcFunc
// fix for variable arguments
//
// Modified by Anthony Clark May 2015
// Fixed the issue where int64 and uint64 could not be passed nativly
// few minor fixes within asm ppcFunc to handle int64 and uint64
// XBox 360 calling convention
// ===========================
// I've yet to find an official document with the ABI for XBox 360,
// but I'll describe what I've gathered from the code and tests
// performed by the AngelScript community.
//
// Arguments are passed in the following registers:
// r3 - r10 : integer/pointer arguments (each register is 64bit)
// fr1 - fr13 : float/double arguments (each register is 64bit)
//
// Arguments that don't fit in the registers will be pushed on the stack.
//
// When a float or double is passed as argument, its value will be placed
// in the next available float register, but it will also reserve general
// purpose register.
//
// Example: void foo(float a, int b). a will be passed in fr1 and b in r4.
//
// For each argument passed to a function an 8byte slot is reserved on the
// stack, so that the function can offload the value there if needed. The
// first slot is at r1+20, the next at r1+28, etc.
//
// If the function is a class method, the this pointer is passed as hidden
// first argument. If the function returns an object in memory, the address
// for that memory is passed as hidden first argument.
//
// Return value are placed in the following registers:
// r3 : integer/pointer values
// fr1 : float/double values
//
// Rules for registers
// r1 : stack pointer
// r14-r31 : nonvolatile, i.e. their values must be preserved
// fr14-fr31 : nonvolatile, i.e. their values must be preserved
// r0, r2, r13 : dedicated. I'm not sure what it means, but it is probably best not to use them
//
// The stack pointer must always be aligned at 8 bytes.
//
