3.4 Analyzer Internals

The Semantic analyzer is a complex engine which has been broken down across several modules. When the Semantic analyzer fails, start with semantic-analyze-debug-assist, then dive into some of these files.

semantic-analyze.el
The core analyzer for defining the current context. The current context is an object that contains references to aspects of the local context including the current prefix, and a tag list defining what the prefix means.
semantic-analyze-complete.el
Provides semantic-analyze-possible-completions.
semantic-analyze-debug.el
The analyzer debugger. Useful when attempting to get everything configured.
semantic-analyze-fcn.el
Various support functions needed by the analyzer.
semantic-ctxt.el
Local context parser. Contains overloadable functions used to move around through different scopes, get local variables, and collect the current prefix used when doing completion.
semantic-scope.el
Calculate scope for a location in a buffer. The scope includes local variables, and tag lists in scope for various reasons, such as C++ using statements.
semanticdb-typecache.el
The typecache is part of semanticdb, but is used primarily by the analyzer to look up datatypes and complex names. The typecache is bound across source files and builds a master lookup table for data type names.
semantic-ia.el
Interactive Analyzer functions. Simple routines that do completion or lookups based on the results from the Analyzer. These routines are meant as examples for application writers, but are quite useful as they are.
semantic-ia-sb.el
Speedbar support for the analyzer, displaying context info, and completion lists.
