Displays the contents of one or more
sconsign files, the signature database files used by the
SCons
build tool.
By default,
sconsign
dumps the entire contents of the sconsign file(s). Without options, individual dependency entries are printed in the following format:
-
depfile: signature timestamp length
implicit_dependency_1: content_signature timestamp length
implicit_dependency_2: content_signature timestamp length
...
action_signature [action string]
None
is printed in place of any missing timestamp,
content signature
(csig) or
build action signature
values for any entry or any of its dependencies. If the entry has no implicit dependencies, or no build action, those lines are omitted.
By default,
sconsign
assumes that any
file
arguments that end with a
.dblite
suffix contains signature entries for more than one directory (that is, was specified by the
SConsignFile
function). Any
file
argument that has no suffix is assumed to be an old-style sconsign file containing the signature entries for a single directory. If neither of those is true,
sconsign
attempts to guess the format. If that does not work, an explicit format may be specified using the
-f
or
--format=
options.
If there are no
file
arguments, the name
.sconsign.dblite
is assumed by default.
OPTIONS
Various options control what information is printed and the format:
-a, --act, --action
-
Prints only the build action information for all entries or the specified entries.
-c, --csig
-
Prints only the content signature (csig) information for all entries or the specified entries.
-d DIRECTORY, --dir=DIRECTORY
-
When the signatures are being read from a
.dblite
file, or the
-f dblite
or
--format=dblite
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
dblite
(the SCons.dblite format used by default, as well as when the
SConsignFile
function is called, except when a filename argument of
None
is given) and
sconsign
(the 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 for the specified entries.
--raw
-
Prints a pretty-printed representation of the raw Python dictionary that holds build information about individual entries (both the entry itself and 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/SCons).
