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 commands and Load commands. Dependencies relative to modules from the Coq library are not printed except if -boot is given.

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).

-I/-Q/-R options

Have the same effects on load path and modules names than for other coq commands (coqtop, coqc).

-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.

-dumpgraph[box] file

Dumps a dot dependency graph in file file.

-exclude-dir dir

Skips subdirectory dir during -R/-Q search.

-sort

Output the given file name ordered by dependencies.

-boot

For coq developpers, prints dependencies over coq library files (omitted by default).

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
