| # 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 |
| } |
| ``` |
