2.4.2. Indexing¶

2.4.2.1. What is indexing?¶

If you already have heard of CTAGS, ETAGS, etc. you already know what an indexer is. A search engine, e.g. Google, is also an indexer. Basically, indexing just makes search and lookup faster.

For C/C++ language, the indexer makes navigating through code faster. But, indexing is not just about navigating thought the code faster. It is also about correctly interpreting code.

If there are some issues with Indexing, we will see editor view like this.

Error in indexing

To fix this issue, we will have to tell Eclipse how to parse the C File.
