Provides a command line interface for stepping through a given flow.
% go install github.com/nyaruka/goflow/cmd/flowrunner

By default it will use a manual trigger to create a session, but the -msg flag can be used
to start the session with a message trigger:
% $GOPATH/bin/flowrunner -msg "hi there" cmd/flowrunner/testdata/two_questions.json 615b8a0f-588c-4d20-a05f-363b0b4ce6f4
If the -repro flag is set, it will dump the triggers and resumes it used which can be used to reproduce the session in a test:
% $GOPATH/bin/flowrunner -repro cmd/flowrunner/testdata/two_questions.json 615b8a0f-588c-4d20-a05f-363b0b4ce6f4
Takes a legacy flow definition as piped input and outputs the migrated definition:
% go install github.com/nyaruka/goflow/cmd/flowmigrate
% cat legacy_flow.json | $GOPATH/bin/flowmigrate
% cat legacy_export.json | jq '.flows[0]' | $GOPATH/bin/flowmigrate
Provides a quick way to test evaluation of expressions which can be used in flows:
% go install github.com/nyaruka/goflow/cmd/exptester
% $GOPATH/bin/exptester '@(10 / 5 >= 2)'
% $GOPATH/bin/exptester '@(TITLE("foo"))'
You can run all the tests with:
% go test github.com/nyaruka/goflow/...
If you've made changes to the flow engine output, regenerate the test files with:
% go test github.com/nyaruka/goflow/test -update
If you need to rebuild the ANTLR grammar files:
go generate ./...
