NAME¶

sconsign - print SCons .sconsign file information

SYNOPSIS¶

sconsign [ options... ] file [ ... ]

DESCRIPTION¶

The sconsign command displays the contents of one or more .sconsign files specified by the user.

By default, sconsign dumps the entire contents of the specified file(s). Each entry is printed in the following format:

file: signature timestamp length
implicit_dependency_1: signature timestamp length
implicit_dependency_2: signature timestamp length
action_signature [action string]

None is printed in place of any missing timestamp, bsig, or csig values for any entry or any of its dependencies. If the entry has no implicit dependencies, or no build action, the lines are simply omitted.

By default, sconsign assumes that any file arguments that end with a .dbm suffix contains signature entries for more than one directory (that is, was specified by the SConsignFile () function). Any file argument that does not end in .dbm is assumed to be a traditional .sconsign file containing the signature entries for a single directory. An explicit format may be specified using the -f or --file= options.

OPTIONS¶

Various options control what information is printed and the format:

-a, --act, --action

Prints the build action information for all entries or the specified entries.

-c, --csig

Prints the content signature (csig) information for all entries or the specified entries.

-d DIRECTORY, --dir=DIRECTORY

When the signatures are being read from a .dbm file, or the -f dbm or --format=dbm options are used, prints information about only the signatures for entries in the specified DIRECTORY.

-e ENTRY, --entry=ENTRY

Prints information about only the specified ENTRY. Multiple -e options may be used, in which case information about each ENTRY is printed in the order in which the options are specified on the command line.

-f FORMAT, --format=FORMAT

The file(s) to be printed are in the specified FORMAT. Legal values are dbm (the DBM format used when the SConsignFile() function is used) or sconsign (the default format used for an individual .sconsign file in each directory).

-h, --help

Prints a help message and exits.

-i, --implicit

Prints the list of cached implicit dependencies for all entries or the the specified entries.

--raw

Prints a pretty-printed representation of the raw Python dictionary that holds build information about individual entry (both the entry itself or its implicit dependencies). An entry's build action is still printed in its usual format.

-r, --readable

Prints timestamps in a human-readable string, enclosed in single quotes.

-t, --timestamp

Prints the timestamp information for all entries or the specified entries.

-v, --verbose

Prints labels identifying each field being printed.

ENVIRONMENT¶

SCONS_LIB_DIR

Specifies the directory that contains the SCons Python module directory (e.g. /home/aroach/scons-src-0.01/src/engine). on the command line.
