Extending the runtime
=====================
See [this](CPP_LAYER.md)
There are a couple ways of doing this
- Creating a shared library (only works if using shared libs)
- Embeding the runtime
- Forking crosslang and adding functionality (I don't support pull requests at this time)
### Shared Library
This assumes you are on linux, if on windows use MyPlugin.dll on mac libMyPlugin.dylib in crosslang project (it would be a good idea to check Env.Platform)
CMakeLists.txt:
```cmake
cmake_minimum_required(VERSION 3.16)
project(MyPlugin)
find_package(TessesCrossLang REQUIRED)
add_library(MyPlugin SHARED lib.cpp)
target_link_libraries(MyPlugin PUBLIC TessesCrossLang::crosslang_shared)
```
lib.cpp:
```c++
#include <CrossLang.hpp>
using namespace Tesses::CrossLang;
void MyPlugin(GC* gc, TRootEnvironment* env)
{
GCList ls(gc);
TDictionary* dict = TDictionary::Create(ls,{
TDItem("MyFunction", TExternalMethod::Create(ls, "A description for function",{"myLong","$optionalList"},[](GCList& ls, std::vector<TObject> args)->TObject {
int64_t n;
if(GetArgument(args,0,n))
{
TList* myLs;
if(GetArgumentHeap(args,1,myLs))
{
//do something with the list
myLs->Add(n);
return TList::Create(ls, {n,myLs});
}
return TList::Create(ls, {n});
}
return nullptr;
}))
});
gc->BarrierBegin();
env->SetVariable("MyPlugin",dict);
gc->BarrierEnd();
}
CROSSLANG_PLUGIN(MyPlugin);
```
main.tcross:
```go
func main(args)
{
Reflection.LoadNativePlugin(FS.MakeFull("libMyPlugin.so"));
var res = MyPlugin.MyFunction(42);
if(TypeOf(res) == "List")
{
Console.WriteLine(res);
}
var res = MyPlugin.MyFunction(42,["Hello","John"]);
if(TypeOf(res) == "List")
{
Console.WriteLine(res);
}
}
```
### Embeding the runtime
CMakeLists.txt:
```cmake
cmake_minimum_required(VERSION 3.16)
project(MyCrossLangBinary)
find_package(TessesCrossLang REQUIRED)
add_executable(MyCrossLangBinary SHARED app.cpp)
target_link_libraries(MyCrossLangBinary PUBLIC TessesCrossLang::crosslang_shared) # or crosslang_static for static linking
```
app.cpp:
```c++
#include <CrossLang.hpp>
using namespace Tesses::CrossLang;
using namespace Tesses::Framework;
void MyPlugin(GC* gc, TRootEnvironment* env)
{
GCList ls(gc);
TDictionary* dict = TDictionary::Create(ls,{
TDItem("MyFunction", TExternalMethod::Create(ls, "A description for function",{"myLong","$optionalList"},[](GCList& ls, std::vector<TObject> args)->TObject {
int64_t n;
if(GetArgument(args,0,n))
{
TList* myLs;
if(GetArgumentHeap(args,1,myLs))
{
//do something with the list
myLs->Add(n);
return TList::Create(ls, {n,myLs});
}
return TList::Create(ls, {n});
}
return nullptr;
}))
});
gc->BarrierBegin();
env->SetVariable("MyPlugin",dict);
gc->BarrierEnd();
}
int main(int argc, char** argv)
{
TF_Init();
if(argc < 2)
{
printf("USAGE: %s <filename.crvm> <args...>\n",argv[0]);
return 1;
}
GC gc;
gc.RegisterEverythingCallback(MyPlugin);
gc.Start();
GCList ls(gc);
TRootEnvironment* env = TRootEnvironment::Create(ls,TDictionary::Create(ls));
Tesses::Framework::Filesystem::LocalFilesystem fs;
TStd::RegisterStd(&gc,env);
env->LoadFileWithDependencies(&gc, &fs, fs.SystemToVFSPath(argv[1]));
TList* args = TList::Create(ls);
for(int arg=1;arg<argc;arg++)
args->Add(std::string(argv[arg]));
auto res = env->CallFunction(ls,"main",{args});
int64_t iresult;
if(GetObject(res,iresult))
return (int)iresult;
return 0;
}
```
main.tcross (needs to be compiled with crossc):
```go
func main(args)
{
//no reflection necessary
var res = MyPlugin.MyFunction(42);
if(TypeOf(res) == "List")
{
Console.WriteLine(res);
}
var res = MyPlugin.MyFunction(42,["Hello","John"]);
if(TypeOf(res) == "List")
{
Console.WriteLine(res);
}
}
```
### Forking (implementing it in runtime library itself)
- edit include/CrossLang.hpp
- in TStd class insert, static void RegisterMyPlugin(GC* gc, TRootEnvironment* env); where MyPlugin is whatever you want
- edit src/runtime_methods/std.cpp
- in TStd::RegisterStd before register everything call TStd::RegisterMyPlugin(gc, env);
- in CMakeLists.txt within list(APPEND CROSSLANG_SOURCE **Many Source Files**) you must add src/runtime_methods/myplugin.cpp
myplugin.cpp:
```c++
#include <CrossLang.hpp>
namespace Tesses::CrossLang
{
void TStd::RegisterMyPlugin(GC* gc, TRootEnvironment* env)
{
GCList ls(gc);
TDictionary* dict = TDictionary::Create(ls,{
TDItem("MyFunction", TExternalMethod::Create(ls, "A description for function",{"myLong","$optionalList"},[](GCList& ls, std::vector<TObject> args)->TObject {
int64_t n;
if(GetArgument(args,0,n))
{
TList* myLs;
if(GetArgumentHeap(args,1,myLs))
{
//do something with the list
myLs->Add(n);
return TList::Create(ls, {n,myLs});
}
return TList::Create(ls, {n});
}
return nullptr;
}))
});
gc->BarrierBegin();
env->SetVariable("MyPlugin",dict);
gc->BarrierEnd();
}
}
```

## CrossLang Handbook
This is a book for my language found [here](https://crosslang.tesseslanguage.com/)
## Statements and loops
#### Declare a variable (it is an expression)
You can (the var is optional but should be used if the root environment has the same variable and you don't want to set it)
```js
var myVariable = 42;
```
#### Set a variable (it is an expression)
```js
myVariable = "I have set the variable to a string";
```
#### If statements
The {} are optional if you only need one statement
```js
var myExpression = 0;
var myOtherExpression = {
mol = 42
};
if(myExpression)
{
Console.WriteLine("myExpression is truthy");
}
else if(myOtherExpression)
{
//this will run based on the condition
Console.WriteLine("myExpression is falsey but myOtherExpression is truthy");
}
else {
Console.WriteLine("both myExpression and myOtherExpression are falsey");
}
```
#### For loop
Note: i will leak, also you can use curly brackets like if
```js
for(var i = 0; i < 42; i++)
Console.WriteLine(i);
```
#### Each loop
```js
enumerable MyItterator()
{
yield 42;
yield 100;
yield 88;
}
each(var item : MyItterator())
{
Console.WriteLine(item);
}
each(var item : [3,7,12])
{
Console.WriteLine(item);
}
/*
This should output
42
100
88
3
7
12
*/
```
#### While loop
```js
while(conditionLikeIf)
{
Console.WriteLine("Hi");
}
//If conditionLikeIf is falsey we never print Hi
//If conditionLikeIf is truthy we print Hi until it is falsey
```
#### Do loop
```js
do(conditionLikeIf)
{
Console.WriteLine("Hi");
}
//If conditionLikeIf is falsey we print Hi once
//If conditionLikeIf is truthy we print Hi until it is falsey
```
#### Try statement
Note: you can't yield, return, break or continue from inside a try statement (also applys to catch and finally due to these being internally closures)
```js
try {
Console.WriteLine("God is good.");
throw "my error";
Console.WriteLine("I am lonely, I am never called.");
}
catch(ex)
{
Console.WriteLine($"I got an error {ex}.");
}
finally {
Console.WriteLine("For God so loved the world that he gave his only begotten Son, that whoever believes in him should not perish but have eternal life.");
}
/*
This should print
God is good.
I got an error my error.
For God so loved the world that he gave his only begotten Son, that whoever believes in him should not perish but have eternal life.
*/
```
#### Switch statement
NOTE: you can use dictionaries with overloaded equals operator (we will pass the switch's expression as the argument)
```js
o = {
operator== = (this,v) => {
//this is implicitly passed by runtime, but you must declare it if you want it
return (v * 7) == 42;
}
};
var val = 6;
switch(val)
{
case 4:
Console.WriteLine("I am four");
break;
case 5:
Console.WriteLine("I am five");
break;
case o:
Console.WriteLine("Hitchhiker's guide to the galaxy meaning of life");
break;
default:
Console.WriteLine("We don't support it we are sorry");
}
```
#### Function declaration
```go
//you can create functions on dictionaries so long as they are on root environment (they are declared there before root scope is evaluated so this is possible)
My.Func.Joel = 59; //Because My.Func.Is.A.Few.Deep creates the dictionaries via runtime
func My.Func.Is.A.Few.Deep(a, b)
{
return a * b;
}
func main(args)
{
Console.WriteLine(My.Func.Is.A.Few.Deep(6,7));
}
```
#### Function inside a function
Oh yeah functions can have exclusively a expression as a body which does not need a return keyword
```go
func main(args)
{
func MyOther(a,b) a * b;
Console.WriteLine(MyOther(a,b));
}
```
#### Document a function
```go
/^
This function returns 42
^/
func MyFunction() 42;
```
#### Return statement
You can also return nothing
```js
return 42;
return;
```
#### Yield statement
This will halt the function's execution and return the running function object (were you can pop the item and resume it)
To automaticly make a function enumerable (with each statement) you must use ``enumerable`` instead of func when declaring your function
```js
yield 42;
```
#### Throw statement
You can catch this with ``try statement`` with ``catch`` clause
```js
throw "You can replace me with another string or any other object";
```
#### Defer statement
Your code will be called when your scope is destroyed
```go
{
defer {
Console.WriteLine("In defer");
}
Console.WriteLine("About to leave scope");
}
Console.WriteLine("Left scope");
/*
The output should be
About to leave scope
In defer
Left scope
*/
```
## Expressions
We will place it as a parameter to a function ``doThing`` but these will work anywhere like setting a variable or another expression
#### Undefined
```js
doThing(undefined);
```
#### Null
```js
doThing(null);
```
#### Boolean
```js
doThing(false);
doThing(true);
```
#### Long
A signed 64 bit number
```js
doThing(94);
doThing(599929022);
```
#### Double
A 64 bit floating pointer number
```js
doThing(5.25);
doThing(942.90204);
```
#### Char
Yes we support single character strings (this escapes a double quote)
```csharp
doThing('\"');
```
#### String
Second is an interopolated string
```csharp
doThing("Hi");
doThing($"My name is {name}");
```
#### List
```js
doThing(
[4,5,9,42,true,"Hi",'\n']
);
```
#### Dictionary
```js
doThing(
{
a = "This is an option",
b = 42,
c = 9
}
);
```
###### Enumerating a dictionary
```js
var dict = { a = 5, b = 42};
each(var item : Dictionary.Items(dict))
{
Console.WriteLine($"Key: {item.Key}");
Console.WriteLine($"Value: {item.Value}");
Console.WriteLine();
}
/*
This prints
Key: a
Value: 5
Key: b
Value: 42
*/
```
###### Getting a value from dictionary
```go
func doThing(data)
{
Console.WriteLine(data.b); //will print 42
}
```
###### Setting a value to dictionary
```go
func doThing(data)
{
data.a = true; //replace a with a different value
data.someFieldThatDoesNotExist = 9; //define a new field entirely
}
```
###### Methods
Note that this is optional but if you do have it it must be the first argument, the this argument points to the dictionary
```go
var item = {
myMethod = (this, a, b) => {
return a * b;
}
};
Console.WriteLine(item.myMethod(6,7)); //prints 42
```
Or
```go
var item = {};
func item.myMethod(this, a, b)
{
return a * b;
}
Console.WriteLine(item.myMethod(6,7)); //prints 42
```
###### Properties
They are declared like every other method except they are prefixed with ``get`` or ``set``
```go
var item = {
getProp = (this)=>{
return 42;
},
setProp = (this,v)=>{
//do something with v
}
};
Console.WriteLine(item.Prop); //equivalent to Console.WriteLine(item.getProp());
item.Prop = 100; //equivalent to item.setProp(100); will do nothing in this example
```
###### Operator overloading
```js
var item = {
operator+ = (this,right) => {
return 4 + a;
}
operator- = (this,right) => {
return 4 - right; //be careful right may be undefined if the negate operator is used
}
};
Console.WriteLine(item + 5); //prints 9
```
###### Array operator overloading
```js
var item = {
GetAt = (index)=>{
return index * 2; //we multiply index by two and return
},
SetAt => (index,value)=>{
Console.WriteLine($"The index was {index} and value was {value}");
}
};
Console.WriteLine(item[21]); //prints 42
item["Hi"] = "John"; //prints The index was Hi and value was John
```
#### ByteArray
```js
var bA = new ByteArray(1);
ba[0] = 42;
Console.WriteLine(ba.ToString()); //prints *
```
###### ByteArray from string
```js
var bA = new ByteArray("Hi");
//we can get bytes like this bA[0] which will be 72
//we can get length by bA.Count or bA.Length
```
#### Embedding files (you can't do this easily in C/C++ and C# not as easy as this)
```js
var bA = embed("myFile.png"); //will embed the file res/myFile.png
//it is stored as a RESO in the crvm file and bA is a ByteArray
//note the argument MUST be a constant string
//note you can access a subdirectory of res as well just use dir/file.bin
```
#### Streams
###### From an existing file
```js
var strm = FS.Local.OpenFile("file.bin","rb");
var data = new ByteArray(1024);
var read = strm.Read(data,0,data.Count);
//use ReadBlock to ensure you have 1024 bytes if not near end of stream
//use WriteBlock to ensure you write the amount you say you need
strm.Close();
```
#### VFS
```js
var myVFS = FS.Local; //FS.Local is the local filesystem
myVFS.CreateDirectory("myDir"); //creates directory in current dir (only local)
myVFS.DeleteDirectory("myDir"); //now we delete it
myVFS.CreateDirectory(Path.FromString(Env.Downloads) / "Folder in Downloads"); //Create a folder in downloads
```
#### Path
```js
var path = / "Path" / "To" / "Directory";
var relativePath = ./"another"/"path";
var combined = path / relativePath;
var someString = "joel";
var combinedAndStr = combined / someString;
var combinedWithExtension = combined + ".mp4";
Console.WriteLine(combined); // outputs /Path/To/Directory/another/path
Console.WriteLine(combined); // outputs /Path/To/Directory/another/path/joel
Console.WriteLine(combinedWithExtension); //outputs /Path/To/Directory/another/path.mp4
//these paths are used with vfs
//to get parent directory use combined.GetParent();
//to get filename use combined.GetFileName();
//to get extension use combinedWithExtension.GetExtension();, it will be the extension including .
//to change the extension use combinedWithExtension.ChangeExtension(".mkv");
//to remove the extension use combinedWithExtension.ChangeExtension(null); or combinedWithExtension.ChangeExtension();
```
#### Html Litterals
```go
//comments are just crosslang ones
//we will be setting to myHtml for the html (returns a string) (it is already html escaped)
myHtml = <h1>{someStringExpression}</h1>;
//a link, in this example we have a dictionary named node with string fields href and text
//lets say node.text equaled List<int> and href contained ./mypage?name=Joel&file=steve.bin myHtml would be equal to "<a target=\"_blank\" href=\"./mypage?name=Joel&amp;file=steve.bin\">List&lt;int&gt;</a>" (the \ are just there to make this a valid string for demonstration purposes, there aren't really backslashes)
myHtml = <a target="_blank" href={node.href}>{node.text}</a>;
//for (works like for loop but is in html form, the for part is not rendered in the final string)
myHtml = <for(var i = 0; i < 42; i++)>
<h6>{i}</h6>
</for>;
//each
myHtml = <each(var item : list)></each>;
//do
myHtml = <do(expr == 42)></do>;
//while
myHtml = <while(expr == 42)></while>;
//if
myHtml = <if(expr == 42)>
<true>
//if expr is 42
</true>
<false>
//if expr is not 42
//you would use another if here instead of else if
</false>
</if>;
myHtml = <null>Hello</null>; //would just be Hello (useful for templating as it works just like div but the null part is not emited into string)
myHtml = <raw(stringExpr)>; //allowing you to emit unescaped html from string into html litteral (useful for templating)

Console.WriteLine(item.myMethod(6,7)); //prints 42
```
Or
```go
var item = {};
func item.myMethod(this, a, b)
{
return a * b;
}
Console.WriteLine(item.myMethod(6,7)); //prints 42
```
###### Properties
They are declared like every other method except they are prefixed with ``get`` or ``set``
```go
var item = {
getProp = (this)=>{
return 42;
},
setProp = (this,v)=>{
//do something with v
}
};
Console.WriteLine(item.Prop); //equivalent to Console.WriteLine(item.getProp());
item.Prop = 100; //equivalent to item.setProp(100); will do nothing in this example
```
###### Operator overloading
```js
var item = {
operator+ = (this,right) => {
return 4 + a;
}
operator- = (this,right) => {
return 4 - right; //be careful right may be undefined if the negate operator is used
}
};
Console.WriteLine(item + 5); //prints 9
```
###### Array operator overloading
```js
var item = {
GetAt = (index)=>{
return index * 2; //we multiply index by two and return
},
SetAt => (index,value)=>{
Console.WriteLine($"The index was {index} and value was {value}");
}
};
Console.WriteLine(item[21]); //prints 42
item["Hi"] = "John"; //prints The index was Hi and value was John
```
#### ByteArray
```js
var bA = ByteArray(1);
ba[0] = 42;
Console.WriteLine(ba.ToString()); //prints *
```
###### ByteArray from string
```js
var bA = ByteArray("Hi");
//we can get bytes like this bA[0] which will be 72
//we can get length by bA.Count or bA.Length
```
#### Embedding files (you can't do this easily in C/C++ and C# not as easy as this)
```js
var bA = embed("myFile.png"); //will embed the file res/myFile.png
//it is stored as a RESO in the crvm file and bA is a ByteArray
//note the argument MUST be a constant string
//note you can access a subdirectory of res as well just use dir/file.bin
```
#### Streams
###### From an existing file
```js
var strm = FS.Local.OpenFile("file.bin","rb");
var data = ByteArray(1024);
var read = strm.Read(data,0,data.Count);
//use ReadBlock to ensure you have 1024 bytes if not near end of stream
//use WriteBlock to ensure you write the amount you say you need
strm.Close();
```
#### VFS
```js
var myVFS = FS.Local; //FS.Local is the local filesystem
myVFS.CreateDirectory("myDir"); //creates directory in current dir (only local)
myVFS.DeleteDirectory("myDir"); //now we delete it
myVFS.CreateDirectory(Path.FromString(Env.Downloads) / "Folder in Downloads"); //Create a folder in downloads
```
#### Path
```js
var path = / "Path" / "To" / "Directory";
var relativePath = ./"another"/"path";
var combined = path / relativePath;
var someString = "joel";
var combinedAndStr = combined / someString;
var combinedWithExtension = combined + ".mp4";
Console.WriteLine(combined); // outputs /Path/To/Directory/another/path
Console.WriteLine(combined); // outputs /Path/To/Directory/another/path/joel
Console.WriteLine(combinedWithExtension); //outputs /Path/To/Directory/another/path.mp4
//these paths are used with vfs
//to get parent directory use combined.GetParent();
//to get filename use combined.GetFileName();
//to get extension use combinedWithExtension.GetExtension();, it will be the extension including .
//to change the extension use combinedWithExtension.ChangeExtension(".mkv");
//to remove the extension use combinedWithExtension.ChangeExtension(null); or combinedWithExtension.ChangeExtension();
```
