Code lines are non-blank, non-comment lines. Types and methods are approximate; see Methodology.

Hand-written vs generated

Files ending in .g.cs (Plato codegen, glTF schema extensions, etc.):

Category	Files	Total lines	Code lines	Types	Methods
Generated (.g.cs)	184	18,014	12,660	446	4,432

Per project

Four meta-packages (Ara3D.SDK, Ara3D.SDK.Core, Ara3D.SDK.Geometry, Ara3D.SDK.IO) contain no .cs sources; they reference other projects for NuGet packaging.

Plato.Generated and Plato.Intrinsics are shared items (.projitems) compiled into Ara3D.Geometry. They are listed separately below; do not add those rows to other project totals (that would double-count shared code).

Methodology

Scope

• Root: src/ only (not ext/, apps/, plugins/, tests/, or toolchain/).
• Source files: all .cs files, recursively.
• Excluded: anything under bin/ or obj/ build output folders.
• Projects: count of .csproj files under src/.

Line classification

Each physical line in a .cs file is classified as:

1. Blank - empty or whitespace only.
2. Comment - starts with //, or inside a /* ... */ block comment.
3. Code - everything else.

Total lines = blank + comment + code. This is a simple lexer, not a full C# parser; edge cases (e.g. // inside a string literal) are rare and not specially handled.

Types

Counted via regex on lines that declare a top-level type keyword:

class, struct, interface, enum, record, delegate

Optional modifiers (public, static, partial, etc.) may precede the keyword. Nested types declared at deeper indentation are still matched. This over-counts slightly when the keyword appears in comments or strings, and under-counts file-scoped types or unusual formatting.

Methods / functions

Counted via regex on lines that look like method declarations: a return type (or modifier chain), an identifier, a parameter list (...), then {, ;, or =>.

Includes most named methods, operators declared like methods, and some constructors. Excludes (approximately):

• Local functions and lambdas
• Property getters/setters without a classic method signature line
• Methods whose declaration spans multiple lines with the parameter list on a later line

Treat method counts as useful ballpark figures, not exact compiler semantics.
