Probably. I could put it in cygutils, or standalone (like the new cygcheck-leaves package is a standalone utility).
Would it be crazy to generate this and make it available on the cygwin web site? Or would the dependency graph generation overload sourceware.org?
The basic processing to generate a .dot file is pretty simple really; just string comparisons and hash manipulations. But as Ryan already pointed out, generating the actual graph in whatever format, is probably compute intensive.
See attached...The svg files in the tarball correspond to each of the --mode options. The tool was invoked as:
setup-ini-graph -i setup.ini -o $dotfile --mode=$mode netpbm followed by (on linux) dot -Tsvg $dotfile > $svgfile Help output:
Usage: setup_ini_graph [options] [packagename [packagename ...]] Options: --help|-? brief help message --man full documentation --version show version information --mode STRING specify the output mode. Possible values: strip-base-and-requirements <default> strip-base-only collapse-base-and-requirements collapse-base-only show-only-base-and-requirements show-base-requirements-only show-all --color STRING set color of specified packages <lightblue> --color-req STRING set color of package requirements <palegreen> --color-base STRING set color of Base packages <plum> --color-base-req STRING set color of Base requirements <pink> --input|-i FILE specify input setup.ini file <STDIN> --output|-o FILE specify output .dot file <STDOUT> --verbose turn on debugging output If packagenames are specified, then only the specified packages and their dependencies are analyzed. If no packages are specified, then all packages in the setup.ini are analyzed. Options: --help Print a brief help message and exits. --man Prints the manual page and exits. --version Prints version information and exits. --mode STRING Specify the output mode. The STRING may be one of the following options: strip-base-and-requirements All packages in the Base category, and packages on which they depend, are completely removed from the output. This is the default mode. strip-base-only All packages in the Base category are completely removed from the output. collapse-base-and-requirements All packages in the Base category, and packages on which they depend, are replaced by a single node 'Base'. collapse-base-only All packages in the Base category are replaced by a single node 'Base'. show-only-base-and-requirements Ignore all packages that are not in the Base category, or are not required by packages in the Base category. show-base-requirements-only As above, but the packages which are members of the Base category are replaced by a single node 'Base'. show-all Chart the entire dependency tree. --color STRING Sets the color to be used for nodes that represent the packages listed on the command line (or all packages extracted from setup.ini that do not fall into one of the other categories below). May be an RGB color name such as palegoldenrod, or an RGB triple of the form #DA70D6. Note that in the latter case, the # must be escaped as \#DA70D6 or '#DA70D6'. The default value is lightblue (#ADD8E6). --color-req STRING Sets the color to be used for nodes that represent packages that are required by the ones listed on the command line, but which do not fall into one of the other categories below. The default value is palegreen (#98FB98). See --color for more information. --color-base STRING Sets the color to be used for nodes that represent packages that are in the Base category. It is also used to color the 'Base' node in the collapse --mode options. The default value is plum (#DDA0DD). See --color for more information. --color-base-req STRING Sets the color to be used for nodes that represent packages which are required by packages in the Base category, but are not in the Base category themselves. The default value is pink (#FFC0CB). --input FILENAME Use the specified input file. Defaults to <STDIN>. --output FILENAME Use the specified output file. Defaults to <STDOUT>. --verbose Turn on verbose output (to STDERR).
