* tests: Use sed instead of grep as a package with no dependencies.Ludovic Courtès2016-01-13
| | | | | * tests/graph.scm ("node-edges"): Choose SED instead of GREP as the example.
* graph: %BAG-WITH-ORIGINS-NODE-TYPE includes the origin's guile.Ludovic Courtès2016-01-02
| | | | | | | | | | Before that it would include #f for most origins since that the default value of 'origin-patch-guile'. * guix/scripts/graph.scm (bag-node-edges): When 'origin-patch-guile' returns #f, use (default-guile). * tests/graph.scm ("bag DAG, including origins"): Check for an edge from O to (default-guile).
* graph: %BAG-EMERGED-NODE-TYPE filters out origins.Ludovic Courtès2016-01-02
| | | | | | | | Fixes <http://bugs.gnu.org/22280>. Reported by Leo Famulari <leo@famulari.name>. * guix/scripts/graph.scm (%bag-emerged-node-type)[edges]: Mimic %BAG-NODE-TYPE. This is a followup to 38b92da.
* graph: Add synthetic test.Ludovic Courtès2015-12-13
| | | | * tests/graph.scm ("node-transitive-edges, no duplicates"): New test.
* graph: Add '%bag-with-origins-node-type'.Ludovic Courtès2015-11-23
| | | | | | | | | | | * guix/scripts/graph.scm (bag-node-edges): Remove 'filter' call. Add case for 'origin'. (%bag-node-type)[edges]: Add filtering here. (%bag-with-origins-node-type): New variable. (%node-types): Add it. * tests/graph.scm ("bag DAG, including origins"): New test. * tests/guix-graph.sh: Add 'bag-with-origins'. * doc/guix.texi (Invoking guix graph): Document it.
* graph: Add procedures to query a node's edges.Ludovic Courtès2015-11-21
