# 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**:
|
||||
|
||||
```sh
|
||||
$ curl ... | fx
|
||||
```
|
||||
|
||||
Or you can pass a filename as the first parameter:
|
||||
|
||||
```sh
|
||||
$ fx data.json
|
||||
```
|
||||
|
||||
## Reducers
|
||||
|
||||
Use [JavaScript](js.md), [Python](python.md), or [Ruby](ruby.md).
|
||||
|
||||
## Streaming mode
|
||||
|
||||
The **fx** supports line-delimited JSON streaming or concatenated JSON streaming.
|
||||
|
||||
```sh
|
||||
$ 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 |
|
||||
|
||||
|
||||
## Configs
|
||||
|
||||
Next configs available for **fx** via environment variables.
|
||||
|
||||
| Name | Values | Description |
|
||||
|----------------|-----------------------------------------------------|-------------------------------------------------------|
|
||||
| `FX_LANG` | `js` (default), `node`, `python`, `python3`, `ruby` | Reducer type. |
|
||||
| `FX_THEME` | `0` (disable colors), `1` (default), `2..9` | Color theme. |
|
||||
| `FX_SHOW_SIZE` | `true` or `false` (default) | Show size of arrays and object in collapsed previews. |

# JavaScript Reducers
|
||||
|
||||
If any additional arguments were passed, fx converts them into a function which
|
||||
takes the JSON as an argument named `x`.
|
||||
|
||||
By default, fx uses builtin JavaScript VM ([goja](https://github.com/dop251/goja)),
|
||||
but also can be used with node.
|
||||
|
||||
```sh
|
||||
export FX_LANG=js # Default
|
||||
```
|
||||
|
||||
Or for usage with node:
|
||||
|
||||
```sh
|
||||
export FX_LANG=node
|
||||
```
|
||||
|
||||
An example of anonymous function used as a reducer:
|
||||
```sh
|
||||
$ echo '{"foo": [{"bar": "value"}]}' | fx 'x => x.foo[0].bar'
|
||||
value
|
||||
```
|
||||
|
||||
The same reducer function can be simplified to:
|
||||
|
||||
```sh
|
||||
$ echo '{"foo": [{"bar": "value"}]}' | fx 'x.foo[0].bar'
|
||||
value
|
||||
```
|
||||
|
||||
Each argument treated as a reducer function.
|
||||
|
||||
```sh
|
||||
$ echo '{"foo": [{"bar": "value"}]}' | fx 'x.foo' 'x[0]' 'x.bar'
|
||||
value
|
||||
```
|
||||
|
||||
Update JSON using the spread operator:
|
||||
|
||||
```sh
|
||||
$ echo '{"name": "fx", "count": 0}' | fx '{...this, count: 1}'
|
||||
{
|
||||
"name": "fx",
|
||||
"count": 1
|
||||
}
|
||||
```
|
||||
|
||||
## Dot
|
||||
|
||||
Fx supports simple JS-like syntax for accessing data, which can be used with any `FX_LANG`.
|
||||
|
||||
```sh
|
||||
$ echo '{"foo": [{"bar": "value"}]}' | fx .foo[0].bar
|
||||
value
|
||||
```
|
||||
|
||||
## .fxrc.js
|
||||
|
||||
Create _.fxrc.js_ file in `$HOME` directory, and define some useful functions.
|
||||
|
||||
```js
|
||||
// .fxrc.js
|
||||
function upper(s) {
|
||||
return s.toUpperCase()
|
||||
}
|
||||
```
|
||||
|
||||
```sh
|
||||
$ cat data.json | fx .name upper
|
||||
ANTON
|
||||
```
|
||||
|
||||
## Node
|
||||
|
||||
```sh
|
||||
export FX_LANG=node
|
||||
```
|
||||
|
||||
Use any npm package by installing it globally. Create _.fxrc.js_ file in `$HOME`
|
||||
directory, and require any packages or define global functions. For example,
|
||||
to access all lodash methods without `_` prefix, put next line into your
|
||||
_.fxrc.js_ file:
|
||||
|
||||
```js
|
||||
Object.assign(global, require('lodash/fp'))
|
||||
```
|
||||
|
||||
And now you will be able to call all lodash methods. For example, see who's been
|
||||
committing to react recently:
|
||||
|
||||
```sh
|
||||
curl 'https://api.github.com/repos/facebook/react/commits?per_page=100' \
|
||||
| fx 'groupBy("commit.author.name")' 'mapValues(size)' toPairs 'sortBy(1)' reverse 'take(10)' fromPairs
|
||||
```
|
||||
|
||||
> To be able to require global modules make sure you have correct `NODE_PATH` env variable.
|
||||
> ```sh
|
||||
> export NODE_PATH=`npm root -g`
|
||||
> ```
|
||||
|
||||
The _.fxrc.js_ file supports both: `import` and `require`.
|
||||
|
||||
```js
|
||||
// .fxrc.js
|
||||
import 'zx/globals'
|
||||
const _ = require('lodash')
|
||||
```
|
||||
|
||||
> If you want to use _.fxrc.js_ for both `FX_LANG=js` and `FX_LANG=node`,
|
||||
> separate parts by `// nodejs:` comment:
|
||||
> ```js
|
||||
> // .fxrc.js
|
||||
> function upper(s) {
|
||||
> return s.toUpperCase()
|
||||
> }
|
||||
> // nodejs:
|
||||
> import 'zx/globals'
|
||||
> const _ = require('lodash')
|
||||
> ```

# Reducers
|

Fx takes a few arguments after the file name, and converts them to a reducer.
|
||||
|
||||
## Node
|
||||
|
||||
Access all lodash (or ramda, etc) methods by using [.fxrc](#using-fxrc) file.
|
||||
|
||||
```bash
|
||||
$ fx data.json 'groupBy("commit.committer.name")' 'mapValues(_.size)'
