Testing the Parser and Emitter

There are several programs to test the parser and emitter.

Parser

echo 'foo: bar' | ./tests/run-parser-test-suite

This will output the parsing events in yaml-test-suite format:

+STR
+DOC
+MAP
=VAL :foo
=VAL :bar
-MAP
-DOC
-STR

For flow style events, you have to enable it with the --flow option:

echo '{ foo: bar }' | ./tests/run-parser-test-suite --flow keep

...
+MAP {}
...

In the future, this will be the default.

You can also explicitly disable this style with --flow off, or output flow style always, with --flow on.

Emitter

run-emitter-test-suite takes yaml-test-suite event format and emits YAML.

./tests/run-parser-test-suite ... | ./tests/run-emitter-test-suite

Options

• --directive (1.1|1.2)

  Prints a version directive before every document.

• --flow on

  Will emit the whole document in flow style.

• --flow off

  Will emit the whole document in block style.

• --flow keep

  Will emit block/flow style like in the original document.

Example:

% echo 'foo: [bar, {x: y}]' |
  ./tests/run-parser-test-suite --flow keep |
  ./tests/run-emitter-test-suite --flow keep
foo: [bar, {x: y}]
