SVK::Command::Log - Show log messages for revisions
log DEPOTPATH log PATH log -r N[:M] [DEPOT]PATH
-r [--revision] ARG : ARG (some commands also take ARG1:ARG2 range) A revision argument can be one of: "HEAD" latest in repository NUMBER revision number NUMBER@ interpret as remote revision number NUM1:NUM2 revision range Unlike other commands, negative NUMBER has no meaning. -l [--limit] REV : stop after displaying REV revisions -q [--quiet] : Don't display the actual log message itself -x [--cross] : track revisions copied from elsewhere -v [--verbose] : print extra information --xml : display the log messages in XML format --filter FILTER : select revisions based on FILTER --output FILTER : display logs using the given FILTER
Display the log messages and other meta-data associated with revisions.
SVK provides a flexible system allowing log messages and other revision properties to be displayed and processed in many ways. This flexibility comes through the use of "log filters." Log filters are of two types: selection and output. Selection filters determine which revisions are included in the output, while output filters determine how the information about those revisions is displayed. Here's a simple example. These two invocations produce equivalent output:
svk log -l 5 //local/project svk log --filter "head 5" --output std //local/project
The "head" filter chooses only the first revisions that it encounters, in this case, the first 5 revisions. The "std" filter displays the revisions using SVK's default output format.
Selection filters can be connected together into pipelines. For example, to see the first 3 revisions with log messages containing the string 'needle', we might do this
svk log --filter "grep needle | head 3" //local/project
That example introduced the "grep" filter. The argument for the grep filter is a valid Perl pattern (with any '|' characters as '\|' and '\' as '\\'). A revision is allowed to continue to the next stage of the pipeline if the revision's log message matches the pattern. If we wanted to search only the first 10 revisions for 'needle' we could use either of the following commands
svk log --filter "head 10 | grep needle" //local/project svk log -l 10 --filter "grep needle" //local/project
You may change SVK's default output filter by setting the SVKLOGOUTPUT environment. See svk help environment for details.
The following log filters are included with the standard SVK distribution:
Selection : grep, head, author Output : std, xml
For detailed documentation about any of these filters, try "perldoc SVK::Log::Filter::Name" where "Name" is "Grep", "Head", "XML", etc.. Other log filters are available from CPAN http://search.cpan.org by searching for "SVK::Log::Filter". For details on writing log filters, see the documentation for the SVK::Log::Filter module.
