[SOLVED] Novice error with macros in .cginc

Unity Engine
1

Hello community!
I’m relatively new to shader. I’ve authored some shaders and now trying to organize my code for easy maintenance. So I decided to write a macro, everything looks OK to me but compiler gives me wired error and I can’t understand why it says so.

The error is

Shader error in 'Some/Test/Shader': syntax error: unexpected token '}' at Assets/TestInclude.cginc(32) (on glcore)

Here’s my .cginc file:

struct appdata {
    float4 vertex : POSITION;
    float4 color : COLOR;
    half2 uv0 : TEXCOORD0;
};     

struct v2f {
    float4 vertex : POSITION;
    float4 color : COLOR;
    half2 uv0 : TEXCOORD0;
};

v2f vert (appdata vertexInput) {
    v2f vertexOutput;
    vertexOutput.vertex = UnityObjectToClipPos(vertexInput.vertex);
    vertexOutput.uv0 = vertexInput.uv0;
    vertexOutput.color = vertexInput.color;
    return vertexOutput;
}

#define SHADER_VARIABLES \
    sampler2D _MainTex; \    
    float4 _Tint;

#define SHADER_FRAGMENT_FUNC(ComputeFragmentCode) \
    float4 frag(v2f vertexOutput) : SV_Target { \
        float4 src = tex2D(_MainTex, vertexOutput.uv0); \
        src.rgb = src.rgb * vertexOutput.color.rgb * _Tint.rgb; \
        src.a = src.a * vertexOutput.color.a * _Tint.a; \
        ComputeFragmentCode \
        return src; \
    }

#define BODY(ComputeFragmentCode) \         
    SHADER_VARIABLES \
    SHADER_FRAGMENT_FUNC(ComputeFragmentCode)

And here’s .shader file:

Shader "Some/Test/Shader"
{
    Properties
    {
        [Header(Properties)]
        _MainTex ("Texture", 2D) = "white" {}
        _Tint("Tint", Color) = ( 1, 1, 1, 1 )
    }
 
    SubShader
    { 
        Tags
        {
            "IgnoreProjector" = "True"
            "Queue" = "Transparent"
            "RenderType" = "Transparent"
            "ForceNoShadowCasting" = "True"
            "PreviewType" = "Plane"
        }
     
        ZWrite Off
        ZTest Off
        Lighting Off
        Cull Off
        Fog { Mode Off }     
     
        Pass {
            BlendOp Add
            Blend SrcAlpha OneMinusSrcAlpha
                             
            CGPROGRAM
         
            #pragma vertex vert
            #pragma fragment frag
            #pragma fragmentoption ARB_precision_hint_fastest

            #include "UnityCG.cginc"     
            #include "TestInclude.cginc"

            BODY( /\* nothing to compute here \*/ )         

            ENDCG
        }
    }

    Fallback "Sprites/Default"
}

Thanks in advance!

It turns out it’s that old error from 1990’s when you can’t put spaces after new line backslashes in C macro, problem solved
