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 Objective Caml 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:

@nf ocamlc -c $(ocamldsort -mli *.ml *.mli) && ocamlc $(ocamldsort -byte *.ml) @fi @cc

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:

@nf TARGET=my_program OCAMLC=ocamlc OCAMLOPT=ocamlopt OCAMLDEP=ocamldep OCAMLDSORT=ocamldsort PPFLAGS=-pp camlp4o

CMO_FILES=$(shell < .depend ocamldsort $(PPFLAGS) -byte *.ml || echo ERROR) CMX_FILES=$(shell < .depend ocamldsort $(PPFLAGS) -opt *.ml || echo ERROR)

$(TARGET): $(CMO_FILES) $(OCAMLC) -o $@ $^

$(TARGET).opt: $(CMX_FILES) $(OCAMLOPT) -o $@ $^

ERROR: @echo Did you run `make depend'? @false

%.cmi:%.mli $(OCAMLC) $(PPFLAGS) -c $<

%.cmo:%.ml $(OCAMLC) $(PPFLAGS) -c $<

%.cmx:%.ml $(OCAMLOPT) $(PPFLAGS) -c $<

clean: rm *.cmo *.cmi *.cmx

depend: $(OCAMLDEP) $(PPFLAGS) *.ml *.mli > .depend

include .depend @fi @cc

The following command-line options are recognized by ocamlsort(1):

-I directory

Add the given directory to the list of directories searched for source files.

-pp pre-command

Command to preprocess file.

-d dep-command

Command to compute dependencies. ocamldep(1) by default.

-mli

Sort files using mli dependencies.

-nox

Ignore filenames containg `*' so that unexpanded wildcards are ignored.

-obj

Print bytecode filenames (.cmo and .cmi) (deprecated: use -byte).

-byte

Print bytecode filenames (.cmo and .cmi).

-opt

Print opt filenames (.cmx and .cmi).

-v

Output version information and exit.

-help, --help

Output help and exit.
