ocamldsort - Dependency sorter for OCaml source files
ocamldsort [ -pp pre-command ] [ -d
dep-command ]
[ -mli ] [ -nox ] [ -obj | -byte | -opt ]
[ filename ] ...
The ocamldsort(1) command scans a set of OCaml source files (.ml and .mli files), sorts them according to their dependencies and prints the sorted files in order to link their corresponding .cmo files.
For ocamldsort(1) to work it must get a list of dependencies generated by ocamldep(1), if the standard input to ocamldsort(1) has been redirected then ocamldsort assumes that this is a dependency file generated by ocamldep(1). Otherwise ocamldsort calls ocamldep(1) to generate the dependency list itself. In either case the source files to be sorted should be given as arguments to the ocamldsort(1) command.
ocamldsort(1) can be used to compile and link simple projects with one command, such as:
ocamlc $(ocamldsort *.ml)
if your project doesn't contain .mli files or:
ocamlc -c $(ocamldsort -mli *.ml *.mli) && ocamlc $(ocamldsort -byte *.ml)
if it contains .mli files.
However for larger projects where separate compilation is desirable, ocamldsort(1) can also be used from within a makefile. Here is a typical makefile example:
TARGET=my_program OCAMLC=ocamlc OCAMLOPT=ocamlopt OCAMLDEP=ocamldep OCAMLDSORT=ocamldsort PPFLAGS=-pp camlp4o MLY=$(shell echo *.mly) MLL=$(shell echo *.mll) GENERATED_ML=$(MLY:.mly=.ml) $(MLL:.mll=.ml) include .generated .depend .ocamldsort $(TARGET): $(CMO_FILES) $(OCAMLC) $(COMPFLAGS) $(LIBS) $^ -o $@ $(TARGET).opt: $(CMX_FILES) $(OCAMLOPT) $(COMPFLAGS) $(LIBS_OPT) $^ -o $@ .generated: $(GENERATED_ML) @touch .generated .depend: .generated $(OCAMLDEP) *.ml *.mli > $@ .ocamldsort: .depend echo CMO_FILES=`< .depend $(OCAMLDSORT) -byte *.ml` > .ocamldsort echo CMX_FILES=`< .depend $(OCAMLDSORT) -opt *.ml` >> .ocamldsort distclean: clean rm -f .generated .depend .ocamldsort rm -f $(GENERATED_ML) rm -f *~ rm -f $(TARGET) clean: rm -f *.cmo *.cmi *.cmx *.o .SUFFIXES: .mli .ml .cmi .cmo .cmx .mll .mly %.cmi:%.mli $(OCAMLC) $(PPFLAGS) $(COMPFLAGS) -c $< %.cmo:%.ml $(OCAMLC) $(PPFLAGS) $(COMPFLAGS) -c $< %.cmi %.cmo:%.ml $(OCAMLC) $(PPFLAGS) $(COMPFLAGS) -c $< %.cmx %.o:%.ml $(OCAMLOPT) $(PPFLAGS) $(COMPFLAGS) -c $< %.ml:%.mll $(OCAMLLEX) $< %.mli %.ml:%.mly $(OCAMLYACC) -v $<
