## Foreach `break` and `continue`
|
||
|
|
|
||
|
|
`break` and `continue` keywords can be used inside foreach loops.
|
||
|
|
|
||
|
|
```meson
|
||
|
|
items = ['a', 'continue', 'b', 'break', 'c']
|
||
|
|
result = []
|
||
|
|
foreach i : items
|
||
|
|
if i == 'continue'
|
||
|
|
continue
|
||
|
|
elif i == 'break'
|
||
|
|
break
|
||
|
|
endif
|
||
|
|
result += i
|
||
|
|
endforeach
|
||
|
|
# result is ['a', 'b']
|
||
|
|
```
|
||
|
|
|
||
|
|
You can check if an array contains an element like this:
|
||
|
|
```meson
|
||
|
|
my_array = [1, 2]
|
||
|
|
if 1 in my_array
|
||
|
|
# This condition is true
|
||
|
|
endif
|
||
|
|
if 1 not in my_array
|
||
|
|
# This condition is false
|
||
|
|
endif
|
||
|
|
```
|
||
|
|
|
||
|
|
You can check if a dictionary contains a key like this:
|
||
|
|
```meson
|
||
|
|
my_dict = {'foo': 42, 'foo': 43}
|
||
|
|
if 'foo' in my_dict
|
||
|
|
# This condition is true
|
||
|
|
endif
|
||
|
|
if 42 in my_dict
|
||
|
|
# This condition is false
|
||
|
|
endif
|
||
|
|
if 'foo' not in my_dict
|
||
|
|
# This condition is false
|
||
|
|
endif
|
||
|
|
```
