Setting up a project that uses a lexer is a bit complicated #186

Closed butlerem01 closed 1 year ago

butlerem01 commented 1 year ago

Every time I set up a C++ project that uses this lexer I have to add one or more of the .cpp files in Reflex's lib directory to my project. Not knowing what I should add or what I shouldn't, I just add all the .cpp files to my project. But it seems excessive. Does it really have to be like this? With Flex, I only need to add the main Flex directory as an include directory so FlexLexer.h can be included, but with Reflex it produces all these dependencies for my project.

The lib/libreflex library has everything. The lib/libreflexmin library is minimized with only the essentials. See the reflex/doc/index.html or visit the manual and read section Minimized library and cross compiling and The RE/flex regex library.

You can build everything from source too, which may require all C++ files in reflex/lib to be compiled, but there aren't that many IMO:
