NAME

obdeps - list dependencies of an object in CDB

SYNOPSIS

obdeps [-a authfile] [-A arch] [-b basedir] [-D|-M] modname

DESCRIPTION

obdeps lists the dependencies of the most recent object of modname. This works for objects only that are already present in CDB, obload may be used to generate them first.

Following options are supported:

-a authfile: specifies a file containing a persistent object of type Shards.Lid that is to be used for authorization. Note that by default (see cdbd) an authorization is not needed because obdeps does not need write access to CDB.
-A arch: list the dependencies of the architecture-dependent object (or machine code) of modname. Architectures must be specified as defined by Architectures.
-b basedir: defines the base path of the compiler data base (CDB). Default is /pub/cdb/oberon.
-D: list the dependencies of the abstract syntax tree generated from the definition (default).
-M: list the dependencies of the abstract syntax tree or machine code generated from the module.

EXAMPLES

List the architecture-independent dependencies of Streams:

oberon$ obdeps Streams

DIAGNOSTICS

obdeps reports ``no such module in CDB'' if modname is completely unknown to CDB and ``requested object not yet in CDB'' if the object is missing. In the latter case, obload may be helpful. If CDB is not found in the Oberon name space, obdeps exits telling ``unable to access CDB root''.

ENVIRONMENT

Following environment parameters allow to override the builtin defaults:

CDB_AUTH: default path of the authorization file.
CDB_BASEDIR: default path of CDB within the Oberon name space.
