| # Commas are Optional after Fields | |
| Commas are optional at the end of fields. | |
| This is also true for the last field. | |
| The convention is to omit them. | |
| <!-- Side Note --> | |
| _CUE borrows a trick from Go to achieve this: the formal grammar still | |
| requires commas, but the scanner inserts commas according to a small set | |
| of simple rules._ | |
| <!-- CUE editor --> | |
| _commas.cue:_ | |
| ``` | |
| { | |
| one: 1 | |
| two: 2 | |
| "two-and-a-half": 2.5 | |
| } | |
| ``` | |
| <!-- JSON result --> | |
| `$ cue export commas.cue` | |
| ```json | |
| { | |
| "one": 1, | |
| "two": 2, | |
| "two-and-a-half": 2.5 | |
| } | |
| ``` |
