Bazel Examples:

Example 1

Running Example 1:

bazel run examples/example1:example1

Check All dependencies of Example 1:

bazel query  --noimplicit_deps \
"deps(//examples/example1:example1)" \
--output graph | dot -Tsvg > output.svg

Example 2

Running Example 2:

bazel run examples/example2:example2

Check All dependencies of Example 2:

bazel query  --noimplicit_deps \
"deps(//examples/example2:example2)" \
--output graph | dot -Tsvg > output.svg

Example 3

Running Example 3:

bazel run examples/example3:example3

Check all dependencies of Example 3:

bazel query  --noimplicit_deps \
"deps(//examples/example3:example3)" \
--output graph | dot -Tsvg > output.svg

Check all paths from lib1 to example3:

bazel query \
"allpaths(//examples/example3:example3, //examples/example3/lib1:lib1)" \
--output graph | dot -Tsvg > output.svg
