Array variables

Wingbot.ai also supports array as variables.

Operations: what to do with an array

Create an array `[...] set`

[...] set | Foo set a single value to array 👇
```
"varName": ["Foo"]
```
[...] set | set an empty value to array 👇
```
"varName": []
```

When there is already some data in variable, it will be overwritten

Add a unique item to array `[]+ add`

[]+ add | Bar - value doesn't exists, so it'll be added

"varName": ["Foo"]
     ⇩
"varName": ["Foo", "Bar"]

[]+ add | Foo - value exists, so the array will remain unchanged
```
"varName": ["Foo"]
     ⇩
"varName": ["Foo"]
```

Remove an item from array `[]- remove`

[]- remove | Bar - value doesn't exists, so it'll be added

"varName": ["Foo", "Bar", "Baz", "Bar"]
     ⇩
"varName": ["Foo", "Baz"]

[]- remove | Bar - value doesn't exists, so the array will remain unchanged
```
"varName": ["Foo"]
     ⇩
"varName": ["Foo"]
```

Push item to array `[]<- push` (to the right)

[]<- push | Bar - just adds an item, no matter it exists or not

"varName": ["Foo", "Bar"]
     ⇩
"varName": ["Foo", "Bar", "Bar"]

Pop item from an array `[]-> pop` (from the right)

[]-> pop - just removes the most right item

"varName": ["Foo", "Bar"]
     ⇩
"varName": ["Foo"]

Shift item from an array `<-[] shift` (from the left)

<-[] shift - just removes the most left item

"varName": ["Foo", "Bar"]
     ⇩
"varName": ["Bar"]

Values, which can be put into an array

plain text (strings) - [...] set | Foo
```
"varName": ["Foo"]
```
lists - [...] set | Foo, Bar\, Baz
```
"varName": ["Foo", "Bar, Baz"]
```
variables - [...] set | {{someVar}}
```
"someVar": "Foo"
"varName": ["Foo"]
```
input text - [...] set | {{$input}}
users message: hello!
```
"varName": ["Hello"]
```
text of quick reply - [...] set | {{$this}} - works only inside a quick reply
quick reply: (Show me more!)
```
"varName": ["Show me more!"]
```

other arrays - [...] set | {{someVar}}

"someVar": ["Foo", "Bar"]
"varName": ["Foo", "Bar"]

entities - [...] set | {{@email}} - when there are more occurrences of the entity, all values will be inserted
users message: send it to foo@mail.com and to bar@mail.com
```
"varName": ["foo@mail.com", "bar@mail.com"]
```

Using arrays in chat messages

Let's have an array like this

"varName": ["Foo", "Bar", "Baz"]

list items

message input

{{#each varName}}{{this}}{{#unless @last}}, {{/unless}}{{/each}}

output

Foo, Bar, Baz

check if an array is empty

message input

{{#if varName}}with items{{else}}empty{{/if}}

output

with items

simply show array items
message input
```
{{varName}}
```
output
```
Foo,Bar,Baz
```
access the first item
message input
```
{{varName.[0]}}
```
output
```
Foo
```
how much items are in the array
message input
```
{{varName.length}}
```
output
```
3
```
