Changes for version 0.21

  • Most of the changes are contributed by Alexander Kriegisch.
  • now we use the 2-clause BSD license. also updated the copyright years.
  • Differentiate between 'end_with' nodes and tree leaves
    • 'end_with' nodes get link URLs and another colour, but normal tree leaves (prerequisites without target definitions) should look just like any other normal node.
    • Fix tests to reflect this change.
  • 'end_with' nodes without prerequisites are no real end nodes
    • So they should be treated like normal nodes, i.e. we
    • do not paint them green,
    • do not add URLs to them,
    • do not call end node callbacks for them which might otherwise cause the creation of trivial, one-node sub-graphs,
    • Please note that there also is one incompatible little change in behaviour: 'end_with' nodes, no matter if with or without prerequisites, now get their commands/recipes printed because this is what a user would expect for a node occurring in a graph with 'trim_mode == false'. One test file was changed to reflect this new behaviour.
  • New API hook 'end_with_callback' for handling 'end_with' events
    • Now users can call 'plot' like this to recursively create sub-graphs for 'end_with' nodes:
    • %targets=( "all" => 0, "install" => 0 ); @targets_to_do = keys %targets; while (@targets_to_do) { $target = @targets_to_do[0]; $gv = $parser->plot( $target, end_with => [ "foo", qr{^.+-bar$} ], no_end_with => [ $target ], end_with_callback => sub($) { my $target = shift; $targets{$target} = 0 unless exists $targets{$target}; }, ... ); ... $targets{$target} = 1; @targets_to_do = grep { ! $targets{$_} } keys %targets; }
  • Set graph name (useful when creating image maps or PS/PDF with links, looks nicer in browser)
  • New options 'normal_end_node_style' and 'vir_end_node_style' (defaulting to light green instead of light yellow background) visually indicate 'end_with' nodes, so the user immediately detects that those nodes have (hidden) sub-nodes which might be accessible via mouse click in image map or SVG scenarios.
  • New option 'url_fct' with default implementation '_url' sets target URLs for 'end_with' nodes, assuming that they will be linked to other graphs starting where the current graph ends. This is useful when generating interlinked SVG files (mode 'svg') or graphics + image maps (mode 'cmapx'). This way users can create hierarchies or webs of graphs and sub-graphs.
  • Change 'fillcolor' to similar, but web-safe yellow #ffff99.
  • Set default font to Arial because when generating SVG the default would otherwise be Times New Roman which looks kinda ugly.
  • New options 'node_trim_fct' and 'cmd_trim_fct' enable user-specified trimming functions for target names/paths and command node content. The previous, hard-wired behaviour is now just a default.
  • Bugfix: Do not falsely display "|" as a node name anymore because it is not a dependency but just a separator between normal and order-only dependencies.
  • Display 'end_with' nodes with surrounding square brackets (e.g. "[my_target]") to visually indicate that the node contains dependent targets which are not displayed.
  • Make sure code nodes have left-justifies rather than centered text by adding "\l" to each end of line instead of "\n", so as for GraphViz to know what we want.
  • Add new options 'no_end_with' and 'no_exclude', specifying exceptions for 'end_with' and 'exclude'. Regex and string matches are allowed. This is especially helpful if the make target name matches an 'end_with' regex pattern but should not be a graph end point. The result would be a single node - not very insightful. ;-) So just add $ARGV[1] (or wherever the caller stores the target name) to 'no_end_with' and you are safe.
  • Changed default layout from top-down to left-right (rankdir=1). This is better for most medium-sized to large graphs.
  • Changed default GraphViz font size to 10.
  • Changed node style for code to "note" shape (looks like a paper sheet), Monospace font (size 8), light grey background (#dddddd).
