Description

I'm using opengrok to index some stl implements for learning. But I find opengrok treats all stl headers as plain text (algorithm,set,map and etc). So I'm wondering if there's a way to let opengrok treats no suffix text file as cpp header file? Thanks for your help.

Research direction
The issue requests that OpenGrok recognize C++ STL header files which lack a file extension. Start by examining the file type detection logic in OpenGrok, likely in the FileAnalyzer or FileTypeManager classes. Check if there is a configuration option for mapping unknown extensions to specific analyzers. The goal would be to add support for mapping files with no extension to the C++ analyzer, possibly by introducing a new configuration property or modifying the detection algorithm. Review the existing codebase in the opengrok indexer module, particularly the analysis package, and look for how existing analyzers are assigned to file types.
