Build analyzer

先查看 issue 中链接的 analyzer interface specification 和 creating-from-scratch guide，然后检查其他 Exercism track 中的 analyzer。确定 C++ track 的 analyzer 范围，并按照规范实现它。当 analyzer 生成所需的 JSON 输出，且该 track 的 config.json 将 .status.analyzer 设置为 true 时，即表示完成。

In Exercism v3, we are making increased use of our v2 analyzers. Analyzers automatically assess student's submissions and provide mentor-style commentary. They can be used to catch common mistakes and/or do complex solution analysis that can't easily be done directly in a test suite.

Each analyzer is track-specific. When a new solution is submitted, we run the track's analyzer, which outputs a JSON file that contains the analysis results.

In v2, analyzer comments were given to a mentor to pass to a student. In v3, the analyzers will normally output directly to students, although we have added an extra key to output suggestions to mentors. If your track already has an analyzer, the only requisite change is updating the outputted copy to be student-facing.

The analyzer is an optional tool though, which means that if a track does not have an analyzer, it will still function normally.

Goal

Build an analyzer for your track according to the spec. Check this page to help you get started with building an analyzer.

It can be very useful to check how other tracks have implemented their analyzer.

If your track already has a working analyzer, please close this issue and ensure that the .status.analyzer key in the track config.json file is set to true.

Choosing between representer and analyzer

There is some overlap between the goals of the representer and the analyzer. If you want to build both, we recommend starting by building the representer for the following reasons:

• Representers are usually (far) easier to implement
• Representers can have a far bigger impact on the mentoring load than analyzers by empowering mentors
• Representers apply to all exercises, whereas analyzers usually target specific exercises or a subset
