# bgldepend(1)

create Bigloo dependencies in makefiles

## NAME

bgldepend - create Bigloo dependencies in makefiles

## SYNOPSIS

**bgldepend** \[ options \] *sourcefile ...*

## DESCRIPTION

**bgldepend** program reads each *sourcefile* in sequence and  parses it to find the module **include** and **import** module directives. **bgldepend** computes the transitive closure of the import relationship. That is, it is sufficient to provide **bgldepend** with a single Bigloo file that  imports all the project file (e.g. the "main" file.)

Every  file  that a *sourcefile* includes, directly or indirectly,  is what **bgldepend** calls a *dependency*. These dependencies are then written to a *makefile* in such a way that **[make(1)](/make/1.md)** will know  which object files must be recompiled when a dependency has changed.

By default, **bgldepend** writes its output on the standard output device. If **bgldepend** is provided with a **-o** *makefile* option,  it will update the *makefile* file. That is, it will search the makefile  for the line:

 \# bgldepend start (don't edit)

and

 \# bgldepend stop

Dependencies will be written in between these two lines.

## OPTIONS

-

  - file

  Is an file implementing a module.  **Afile** reads that file to discover the name of the implemented module.

- \-search-path \<path\>

  Add *path* to the directory list read for searching Bigloo source files.

- \-exclude-path \<path\>

  Exclude *path* from the directory list read for searching Bigloo  source files.

- \-suffix \<suf\>

  Adds *suf* to the **bmake** source file suffixes list. Default  suffixes are "scm", "sch" and "bgl".

- \-v

  Verbose mode

- \-o \<makefile\>

  The name of the *makefile* file to be updated

## EXAMPLE

Normally,  **bgldepend** will be used in a makefile target so that typing \`\`make bgldepend'' will bring the dependencies up to date for the makefile.  For example,

   MAIN=foo.scm

   SRCS = $(MAIN) bar.scm gee.scm

   bgldepend:

       bgldepend -o Makefile $(MAIN)
