tcp的read方法阻塞，内部好像是调用阻塞的go socket函数，能不能改成magpie语言层上while循环手动从缓冲区read()读取数据

We are compiler lover, can i add your qq or wechat ?

@haifenghuang

Running httpclient.mp causes a Syntax Error:

$ ./magpie examples/httpclient.mp
Syntax Error: <examples/httpclient.mp:1:4> - expected next token to be (, got ) instead
$

The magpie is amazing! Thanks!

@haifenghuang

Please add multiline code blocks to the REPL. It would be very convenient.

>>> fn sum(x, y) {
...     return x + y
... }
>>>

instead of:

>>> fn sum(x, y) { return x + y }

The magpie is amazing! Thanks!

@haifenghuang Have you planned to make Magpie compilable or adding bytecode compiled?

I saw ok programming language and it would be nice to see Magpie become compilable programming language.

@haifenghuang

You can add something like this:

from module include *

function() // instead of module.function()

The magpie is amazing! Thanks!

When I use json.readFile(). How do I check the type is an array or an object?

@haifenghuang When do you want to implement interface, public, private, protected keywords?

I ask because interface, public, private and protected keywords available, but they do not work.

@haifenghuang

When I trying to just define variable I got this error:

Syntax Error: <file:2:0> - expected token to be comma, got EOF instead.

But it works if I'll add ; at the end of let a.

Is it possible to fix this?

@haifenghuang

Instead of displaying an error, REPL continues to read input:

magpie>> include thismoduledoesnotexists
...
...

I think this is because of #5.

@haifenghuang

Colors in magpie does not works on windows:

magpie>> [1mlet[m

But I found a way to fix this. If you add this in the main() function in main.go (only for windows, on other platform there will be an error) then the colors will work:

handle := syscall.Handle(os.Stdout.Fd())
kernel32DLL := syscall.NewLazyDLL("kernel32.dll")
setConsoleModeProc := kernel32DLL.NewProc("SetConsoleMode")
setConsoleModeProc.Call(uintptr(handle), 0x0001|0x0002|0x0004)

On windows it successfully compiled, but on Linux/Darwin/other:

undefined: syscall.Handle
undefined: syscall.NewLazyDLL

I do not know how to make go compiler to compile this part of code only for windows because there is no preprocessor in golang (#ifdef).

In fact, I want to run app in background, such as
app & but it was blocked.
Is there go-routine feature?

Use case description:

MAIN: for (i=0;...) {
   for (j=0;....) {
      if (....) {
         break MAIN
      }
    }
}

Hi,
For non-nested json string.....just Key=Value type...
After json unmarshel input string, how can I get the properties of json object?
My means is how to get "keys" from the json object?
Or....How to translate json to hash?
Thx.

i am looking for your code and i found that following functionality is not working in you code.
magpie>> let hash={}
magpie>> hash
magpie>> print(hash)
magpie>> hash["one"]["two"]
1index error: type NIL_OBJ is not indexable
magpie>> hash["one"]["two"]++
1index error: type NIL_OBJ is not indexable
1unsupported operator for postfix expression:'++' and type: NIL_OBJ

@haifenghuang Why stdin >> variable method scans only a char, not a line in REPL?

Also stdin.read() too

This is only in REPL, if running this code from file, everything works correctly.

@haifenghuang Now I can't compile it:
