The filebasename specifies the felix program to run. If there is an extension it should be .flx, if not it defauts to .flx.

flxl lexes the input and prints the token list to standard output

flxp lexes and parses the input and prints the parse tree to standard output

flxm lexes, parses, folds constants and performs macro expansion of the input and prints the AST tree to standard output

flxd lexes, parses and desugars the the input and prints the desugared AST tree to standard output

flxb lexes, parses, desugars and binds identifiers and prints the bindings to standard output

flxcc reads a preprocessed C header file and writes Felix wrapper bindings to out. The command accepts an argument which specifies wrapper generation configuration parameters.

flx_doc Felix documentation generator. The −−outdir=dirname option specifies the directory into which to put documentation. Defaults to out_doc. Each of the subsequently listed filenames should be a Felix (*.flx) file, which is treated as a library. The documentation processor produces a set of HTML files documenting the interface. Comments specified with either the publish prefix or comment statement are also emitted into the documentation.

flxg lexes, parses, desugars, binds, and generates C++ code. Two files, filebase.cpp and filebase.hpp are created. Use the -v option for verbose output.

flx is a load and go test harness which compiles its argument to C++, compiles and links the C++ using gcc, then executes the resulting library using flx_run.

−−test
Forces use of the Felix system in the current directory. Intended for use testing during development.

−−force
Forces both Felix and C++ recompilation and linking. Normally, timestamps are checked, and compilation is skipped if the program is up to date.

−−echo
Indicates what the flx script is doing, prints external commands such as the C++ compilation command line. Use to check your options are being processed correctly by the flx script.

−−debug
Tells the flxg compiler to print extensive details of its compilation process to help debugging.

−−inline
Enables experimental inlining features. May slow down Felix compilation significantly. May cause significant code bloat.

−−optimise −−optimize
Enables inlining and passes -O3 to the C++ compiler.

−−static
Force linking of an executable instead of a shared library.

−−version
Prints version and exits.

−−time
Times execution of the target program using the time command. Note −− compilation time is not included.

−−help
Runs ’man flx’ and exits.

-c
Generates but does not execute the program. Warning −− this option is part of the felix options. It must be given before any C++ compiler options, or it will just be passed directly to the C++ compiler, resulting in generation of object files without linking, but the flx script will try to run the linked output anyhow (possibly resulting in an old version being executed).

−−pkg=<pkg-config pkg>
Specifies the particular C library is required. This option causes the required flags to be added to compilation and link steps to allow #includes to find the headers, and to link the library to the program. This option uses the pkg-config program to obtain this data. May be specified any number of times.

*.cpp *.cxx *.o *.a
Files ending in these extensions are normally recognized by the C/C++ compiler/linker harness are passed to it during C++ compilation and linkage steps. This allows linking Felix to arbitrary C, C++ codes available as source, object files, or in an archive.

<link opts>
Various options normally recognized by the C/C++ compiler/linker harness are passed through to it transparently.

filebasename
The name of the Felix program to run. May be given with or without the .flx extension. This program is compiled with the flxg driver to produce filebasename.cpp which is then compiled and linked with other specified files. Currently only one Felix file may be given.

flxg is the compiler proper. flx[lpmdb] are provided to aid in debugging, and perform successive phases of the compilation process.

flx is a script which combines felix compilation, C++ compilation of the output, and execution using the standard program driver, for rapid prototyping in a scripting style.

flxcc is the wrapper generator for C headers.

flx_doc is the documentation generator. It can be used to create HTML pages documenting any Felix code files.

flx_run is the standard prgram driver. Its argument is a shared library which is passed to dlopen (note you need to use ./lib.so on linux to preempt the stanard search path).

The driver creates a single thread from the libraries main entry point _init_ and runs the thread until it terminates, then exits. The message type here is void and the driver exists with an error diagnostic if the thread tries to read any messages.

flx_sif is like flx_run except that it reads standard input and passes lines to the single instance thread. The lines include terminating newline character. A zero length line is passed at end of file. The message types is std::basic_string<char>

*.flx
Felix input files.

*.cpp *.hpp
Generated C++ output files.

*.par
Precompiled header file.
