## 项目历史与用法

GNU Complexity is a small GNU static-analysis tool for measuring the complexity of C functions, designed as a more human-comprehension-oriented alternative to simple McCabe-style path counts.

### 项目历史

The GNU Complexity manual documents version 0.4 as of May 2011 and describes a tool by Bruce Korb for analyzing C function complexity. Its rationale is explicit: McCabe-style scoring and `pmccabe` are useful for testing effort, but GNU Complexity tries to better rank functions that are difficult for humans to understand by considering length, nesting, switch bodies, and complicated boolean expressions.

### 采用历史

GNU Complexity has a narrow adoption footprint compared with larger GNU developer tools. Its significance is in the code-review and maintenance niche: it gives C maintainers a command-line metric that can point to suspicious functions in unfamiliar code, estimate testing or comprehension effort, and produce sorted score tables and histograms.

### 使用方式

Practitioners run `complexity` over C source files to report procedure scores, line counts, source locations, and optional histograms. The manual's example runs the tool against its own source with a low threshold, illustrating use as a quick audit tool for ranking functions before refactoring or review.

### 为什么软件包爱好者会关心

For package nerds, GNU Complexity is interesting because it embodies a Unix-tool approach to maintainability: one command, text output, tunable thresholds, and a documented scoring model. It is useful in distributions as a lightweight companion to older tools such as `pmccabe` rather than as a large static-analysis framework.

### 时间线

- 2011: GNU Complexity web page and manual documented version 0.4.
- 2011: Manual rationale compared GNU Complexity with `pmccabe` and explained its scoring model.

### Related projects

- `pmccabe` is the comparison point used throughout the GNU Complexity manual.
- `unifdef` is discussed in the parsing model as a way to handle preprocessor-conditional source.
