Oh My Posh Unity Segment

Website

Tags: Go

Oh My Posh is a custom prompt engine for any shell that is structured around the concept of “segments”, which renders a single context like showing the current folder, user information or git status when relevant.

Because I frequently use Unity Engine and am a fan of the oh-my-posh terminal extension, I decided to contribute a custom segment that displays the Unity version and C# version of the current working directory. This was my first time using Go.

  • Change IList parameters to concrete types (array and OffsetArray)
  • Use Span instead of OffsetArray
  • Add stackalloc and MemoryPool optimizations

Allocate temporary arrays on the stack instead of the heap when the size is small enough. Otherwise, use a pool and slice it to the needed size.

float[] seedArr = null;
Span<float> seed = _totalOctaveLines <= 128
    ? stackalloc float[_totalOctaveLines]
    : (seedArr = ArrayPool<float>.Shared.Rent(_totalOctaveLines));

seed = seed.Slice(0, _totalOctaveLines);
