Documentation
The fx can work in two modes: as a reducer or an interactive viewer.
To start the interactive mode pipe a JSON into fx:
$ curl ... | fx
Or you can pass a filename as the first parameter:
$ fx data.json
Reducers
Use JavaScript, Python, or Ruby.
Streaming mode
The fx supports line-delimited JSON streaming or concatenated JSON streaming.
$ echo '
> {"message": "hello"}
> {"message": "world!"}
> ' | fx .message
hello
world!
Interactive mode
Type ? to see the full list of available shortcuts while in the interactive mode.
Search
Press / and type regexp pattern to search in the current JSON.
Search is performed on the internal representation of the JSON without newlines.
Type n to jump to the next result, and N to the previous
Selecting text
You can't just select text in fx. This is due to the fact that all mouse events are redirected to stdin. To be able to select again you need to instruct your terminal not to do it. This can be done by holding special keys while selecting:
| Key | Terminal |
|---|---|
Option+Mouse |
iTerm2, Hyper |
Fn+Mouse |
Terminal.app |
Shift+Mouse |
Linux |
