(0) What is lolo

lolo extracts symbols from a sequence of input characters belonging to the ASCII or Unicode sets. lolo scanners can be extended without access to the source code: symbol recognizers can be derived by inheritance and an executing scanner can be reconfigured for different contexts. Recognizer actions are represented by objects which may be replaced at any time. Recognizers need not be based on finite state automata; therefore, lolo can recognize symbols that systems like lex cannot recognize directly. 

lolo was developed in 2001 as successor to oolex. Both tools are part of Bernd K焗l's PhD thesis about object-orientation in compiler construction.

(1) Directories

lolo            The lolo framework.
lolo/scans      The library of symbol recognizer classes.
lolo/test       This package collects some tests.
make            Collects the platform dependent makefiles. The makefile named
                makefile.$OSTYPE is the makefile for your system.



(2) Compilation

All sources can be compiled with the use of gnu make and makefiles. For the most popular operating systems platform dependent makefiles are supported. make/Makefile.$OSTYPE is the makefile for your system.

For Windows only cywgin is supported (see http://www.cygwin.com), because Windows comes without make, and nmake is not compatible to make. The platform makefile for cywgin is make/Makefile.cygwin.

The makefile supports more than the lolo project. So they are much too big for the compilation of lolo...

Every package directory contains a makefile to build, clean and (optionally) test the sources. Every makefile supports three targets:

make all        Builds (recursively in subdirectories) all files.
make clean      Removes (recursively in subdirectories) all generated files.
make test       This target depends on the target all and runs some test. Currently
                only the package lolo/test has a test target.

So to generate and compile all lolo classes and files just enter the lolo directory and call "make" or "make all" and this will build everything.
