What is there, counted

What the library holds

A foundation is claimed in words and shown in files. Here is what the library holds, counted from a checkout of it: its domains, its engine, its tests and its design documents.

The library map

Every domain folder of the library, with its files and its lines of code. Tests, documents and archives are not counted as code.

The engine

The engine is written in Zig: 375 source files, 160,063 lines. The largest, with their lines: list (6,518), string (5,052), ring_bridge_stats (4,476), ring_bridge_string (4,335), eigen_general (4,254), linalg (3,309), reactor (2,969), graph (2,808).

The tests

5,284 test files in 158 folders, of which 527 are scenario guards and 4,474 are numbered tests of the classic form.

The design documents

43 design documents, for anyone who wants to understand why the library is made as it is. Each title opens the document on GitHub; the number is its lines.

These numbers were read from a copy of the library at commit 4a184e6f0 by a tool of the site (tools/depth_run.py), counted as files and lines of text. They are not runs.
