1# Testing the Parser and Emitter 2 3There are several programs to test the parser and emitter. 4 5## Parser 6 7 echo 'foo: bar' | ./tests/run-parser-test-suite 8 9This will output the parsing events in yaml-test-suite format: 10 11 +STR 12 +DOC 13 +MAP 14 =VAL :foo 15 =VAL :bar 16 -MAP 17 -DOC 18 -STR 19 20For flow style events, you have to enable it with the `--flow` option: 21 22 echo '{ foo: bar }' | ./tests/run-parser-test-suite --flow keep 23 24 ... 25 +MAP {} 26 ... 27 28In the future, this will be the default. 29 30You can also explicitly disable this style with `--flow off`, or output 31flow style always, with `--flow on`. 32 33## Emitter 34 35run-emitter-test-suite takes yaml-test-suite event format and emits YAML. 36 37 ./tests/run-parser-test-suite ... | ./tests/run-emitter-test-suite 38 39## Options 40 41* `--directive (1.1|1.2)` 42 43 Prints a version directive before every document. 44 45* `--flow on` 46 47 Will emit the whole document in flow style. 48 49* `--flow off` 50 51 Will emit the whole document in block style. 52 53* `--flow keep` 54 55 Will emit block/flow style like in the original document. 56 57Example: 58``` 59% echo 'foo: [bar, {x: y}]' | 60 ./tests/run-parser-test-suite --flow keep | 61 ./tests/run-emitter-test-suite --flow keep 62foo: [bar, {x: y}] 63``` 64
