pyJsonEdit
Edit parts of inconsistently formatted json.
It's just a bit slower that doing this by hand!
matcher
Now you can easly select nodes in json tree
syntax:
| selector | action | node type | comments |
|---|---|---|---|
| * | select all items in current node | - | |
| [n] | select n-th item of curent node | array | |
| {n} | select n-th item of curent node | object | |
| key | select node chilld by name | object | |
| "key" | select node chilld by name | object | |
| > | mark current node as seleced | - | |
| a=b | check if current node has child 'a' with value 'b' | object | |
| :before | add text before selected node | - | must at end of pattern |
| :after | add text after selected node | - | must at end of pattern |
example 1:
key > [0]
this pattern will match one element by:
- selecting "key" element in root node (assuring that is an object)
- select first element in it (assumintg its an array)
example 2:
name > *
this pattern will match multiple elements by:
- selecting "name" element in root node (assuring that is an object)
- select all element in it
