The sconsign command displays the contents of one or more signature ("sconsign") files specified by the user.
By default, sconsign dumps the entire contents of the specified file(s). Without the verbose option, 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, build signature ("bsig"), or content signature ("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. The verbose option expands the display into a more human readable format.
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 ends in
.dblite
is assumed to be a traditional
.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.
Various options control what information is printed and the format:
Prints the build action information for all entries or the specified entries.
Prints the content signature (csig) information for all entries or the specified entries.
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.
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.
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).
Prints a help message and exits.
Prints the list of cached implicit dependencies for all entries or for the specified entries.
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.
Prints timestamps in a human-readable string, enclosed in single quotes.
Prints the timestamp information for all entries or the specified entries.
Prints labels identifying each field being printed.
