NAME

       coqdep - Compute inter-module dependencies for Coq and Caml programs

SYNOPSIS

       coqdep [ -w ] [ -I directory ] [ -coqlib directory ] [ -c ] [ -i ] [ -D ] [ -slash ] filename ...  directory ...

DESCRIPTION

       coqdep compute inter-module dependencies for Coq and Caml programs, and prints the dependencies on the standard output in a format readable
       by make.  When a directory is given as argument, it is recursively looked at.

       Dependencies of Coq modules are computed by looking at Require commands (Require, Require Export, Require Import), Declare ML  Module  com-
       mands and Load commands. Dependencies relative to modules from the Coq library are not printed.

       Dependencies of Caml modules are computed by looking at open directives and the dot notation module.value.

OPTIONS

       -c     Prints the dependencies of Caml modules.	(On Caml modules, the behaviour is exactly the same as ocamldep).

       -w     Prints  a warning if a Coq command Declare ML Module is incorrect. (For instance, you wrote `Declare ML Module "A".', but the module
	      A contains #open "B"). The correct command is printed (see option -D). The warning is printed on standard error.

       -D     This commands looks for every command Declare ML Module of each Coq file given as argument and complete (if needed) the list of Caml
	      modules. The new command is printed on the standard output. No dependency is computed with this option.

       -slash Prints paths using a slash instead of the OS specific separator. This option is useful when developping under Cygwin.

       -I directory
	      The files .v .ml .mli of the directory directory are taken into account during the calculus of dependencies, but their own dependen-
	      cies are not printed.

       -coqlib directory
	      Indicates where is the Coq library. The default value has been determined at installation time, and therefore this option should not
	      be used under normal circumstances.

SEE ALSO

       ocamlc(1), coqc(1), make(1).

NOTES

       Lexers (for Coq and Caml) correctly handle nested comments and strings.

       The treatment of symbolic links is primitive.

       If two files have the same name, in two different directories, a warning is printed on standard error.

       There is no way to limit the scope of the recursive search for directories.

EXAMPLES

       Consider the files (in the same directory):

	    A.ml B.ml C.ml D.ml X.v Y.v and Z.v

       where

       +      D.ml contains the commands `open A', `open B' and `type t = C.t' ;

       +      Y.v contains the command `Require X' ;

       +      Z.v contains the commands `Require X' and `Declare ML Module "D"'.

       To get the dependencies of the Coq files:

	      example% coqdep -I . *.v
	      Z.vo: Z.v ./X.vo ./D.cmo
	      Y.vo: Y.v ./X.vo
	      X.vo: X.v

       With a warning:

	      example% coqdep -w -I . *.v
	      Z.vo: Z.v ./X.vo ./D.cmo
	      Y.vo: Y.v ./X.vo
	      X.vo: X.v
	      ### Warning : In file Z.v, the ML modules declaration should be
	      ### Declare ML Module "A" "B" "C" "D".

       To get only the Caml dependencies:

	      example% coqdep -c -I . *.ml
	      D.cmo: D.ml ./A.cmo ./B.cmo ./C.cmo
	      D.cmx: D.ml ./A.cmx ./B.cmx ./C.cmx
	      C.cmo: C.ml
	      C.cmx: C.ml
	      B.cmo: B.ml
	      B.cmx: B.ml
	      A.cmo: A.ml
	      A.cmx: A.ml
