Missing 'inline' keyword, C# 7.0 Tuples

[rogerbarton]

Hi @rogerbarton rogerbarton,

I am trying your solution and have some warning and exception, do you have any thought about this?

The inline keyword is missing from the list of modifiers. I will add this quickly...

[Feng-Seng]

HaHa, thank you sooooooo much!!

[rogerbarton]

It's been added, run pip install git+https://github.com/rogerbarton/sphinx-csharp.git to get the latest version and try it again

[Feng-Seng]

Thanks, it's getting better.

But I still got 2 warnings and 1 exception as follows:

----------------------
WARNING: Type signature invalid, got List< string >)
WARNING: Variable signature invalid: NSBone

Exception：
  File "/opt/homebrew/lib/python3.9/site-packages/sphinx_csharp/csharp.py", line 237, in parse_type_signature
    match = CLASS_SIG_RE.match(sig.strip())
AttributeError: 'NoneType' object has no attribute 'strip'
----------------------

Any thoughts about these?

[rogerbarton]

The first warning seems to be because of the brackets (.. , ...) in the original warning:

WARNING: Method signature invalid: static inline Dictionary< ESkinPart,(List< string >, List< string >)> initAssetMap2 ()

I assume this is syntax for a tuple or something similar. Parsing this as a type has not been implemented. I will have a look at this...

For the second warning, do you know which line this is coming from? maybe search your code for NSBone?

[rogerbarton]

I guess for now you could write Tuple<List< string >, List< string >> for this one function as a workaround. This might also fix the other warning

[Feng-Seng]

For the second warning, I am not sure which line induces this warning since the NSBone has been used in several places in 2 cs files as follows.

First .cs file.

namespace xx.xxxxx
{
    //no-scale-bone
    public struct NSBone
    {
        public NSBone(Vector3 v, Quaternion q)
        {
            localPos = v;
            localRot = q;
        }
        public Vector3 localPos;
        public Quaternion localRot;
    }
    internal class NSPair
    {
        public NSPair(Vector3 v, Quaternion q)
        {
            _original.localPos = v;
            _original.localRot = q;
        }
        public NSBone _original;
        public NSBone _lastSaved;
    }
    public class Data
    {
        .......
        (NSBone, NSBone) NSBonePair(Vector3 v, Quaternion q)
        {
            return (new NSBone(v, q), new NSBone(v, q));
        }

Another .cs file

namespace xx.xxxxx
{
    ......
          public bool GetBindingPose(string name, out NSBone localTransform)
    ......
}

Could those information sufficient for you?

[Feng-Seng]

For the first warning, I will try what you said, thanks!!

[rogerbarton]

This is probably from the line:

(NSBone, NSBone) NSBonePair(Vector3 v, Quaternion q) {...}

So the same issue with the tuple short hand type but for the return type of the function.

[rogerbarton]

I've had a look at implementing the C# 7.0 tuples, but this seems to be quite complicated. So it will not be supported for now.

[Feng-Seng]

Hi @rogerbarton ,

That's no problem.
But could you print the file / line causes the warning / error in the warning / error message?
For example, which xml (or CS) file cause this warning / error.

[Feng-Seng]

Another question is, do you know why the warning causes the exception? In usual case, only the errors could stop the execution.

Is there any way to get the result, even there are warning message?

[rogerbarton]

Yes, its because a None is propagated when the regex does not match. I'm currently working on cleaning things up and producing better errors...

[rogerbarton]

I should have probably checked this earlier, but doxygen does not yet support these C# 7.0 tuples, see doxygen/doxygen#7633. So the input for breathe is garbage.

But could you print the file / line causes the warning / error in the warning / error message?
For example, which xml (or CS) file cause this warning / error.

I have no idea how to get this information, so for now I've just set it to point to the rst file/line.
