What To Include

libircd headers are organized into several aggregates groups

As a C++ project there are a lot of header files. Header files depend on other header files. We don't expect the developer of a compilation unit to figure out an exact list of header files necessary to include for that unit. Instead we have aggregated groups of header files which are then precompiled. These aggregations are mostly oriented around a specific project dependency.

Note: The term 'stack' may be found in place of the preferred term 'group' in other documentation.

• Standard Include group <ircd/ircd.h> is the main header group. This group involves the standard library and most of libircd. This is what an embedder will be working with. These headers will expose our own interfaces wrapping 3rd party dependencies which are not included there.

  There are actually two files in play here: <ircd/stdinc.h> and <ircd/ircd.h>. We have to offer two different pre-compilations: one with -fPIC and one without. Therefor the contents are in <ircd/stdinc.h> and the preprocessor determination for which is in <ircd/ircd.h>.

• Boost ASIO include group <ircd/asio.h> is a header group exposing the boost::asio library. We only involve this header in compilation units working directly with asio for networking et al. Involving this header file slows down compilation compared with the standard group.

• Boost Spirit include group <ircd/spirit.h> is a header group exposing the spirit parser framework to compilation units which involve formal grammars. Involving this header is a monumental slowdown when compiling.

• JavaScript include group <ircd/js/js.h> is a header group exposing symbols from the SpiderMonkey JS engine. Alternatively, <ircd/js.h> is part of the standard include group which includes any wrapping to hide SpiderMonkey.

• MAPI include group <ircd/mapi.h> is the standard header group for modules. This group is an extension to the standard include group but has specific tools for pluggable modules which are not part of the libircd core.
