This is the help information for the `pert calculate` command:
|
||
|
|
|
||
|
|
Usage: calculate|c [options] <file>
|
||
|
|
|
||
|
|
calculate data on given JSON document
|
||
|

||
|
|
Options:
|
||
|
|
|
||
|
|
-h, --help output usage information
|
||
|
|
-j, --json output json data
|
||
|
|
|
||
|
|
## Data format
|
||
|
|
|
||
|
|
This is a valid input document:
|
||
|
|
|
||
|
|
```json
|
||
|
|
[
|
||
|
|
{"id": 0, "duration": 3},
|
||
|
|
{"id": 1, "duration": 1},
|
||
|
|
{"id": 2, "duration": 2, "depends": [0]},
|
||
|
|
{"id": 3, "duration": 5, "depends": [1]},
|
||
|
|
{"id": 4, "duration": 5, "depends": [1]},
|
||
|
|
{"id": 5, "duration": 2, "depends": [2,3,4]}
|
||
|
|
]
|
||
|
|
```
|
||
|
|
|
||
|
|
And this is the output of the `calculate` command on the previous document using the `--json` flag:
|
||
|
|
|
||
|
|
```json
|
||
|
|
[{"id":0,"duration":3,"startDay":0,"endDay":3,"permittedDelay":0},{"id":1,"duration":1,"startDay":0,"endDay":1,"permittedDelay":0},{"id":2,"duration":2,"depends":[0],"startDay":3,"endDay":5,"permittedDelay":1},{"id":3,"duration":5,"depends":[1],"startDay":1,"endDay":6,"permittedDelay":0},{"id":4,"duration":5,"depends":[1],"startDay":1,"endDay":6,"permittedDelay":0},{"id":5,"duration":2,"depends":[2,3,4],"startDay":6,"endDay":8}]
