## Interpolation de variables
|
||||
|
||||
Il est possible d'utiliser de l'interpolation de variables d'environnement dans le fichier de configuration via la syntaxe `${var}`.
|
||||
|
||||
Les fonctions d'interpolation suivantes sont également disponibles:
|
||||
|
||||
- `${var^}`
|
||||
- `${var^^}`
|
||||
- `${var,}`
|
||||
- `${var,,}`
|
||||
- `${var:position}`
|
||||
- `${var:position:length}`
|
||||
- `${var#substring}`
|
||||
- `${var##substring}`
|
||||
- `${var%substring}`
|
||||
- `${var%%substring}`
|
||||
- `${var/substring/replacement}`
|
||||
- `${var//substring/replacement}`
|
||||
- `${var/#substring/replacement}`
|
||||
- `${var/%substring/replacement}`
|
||||
- `${#var}`
|
||||
- `${var=default}`
|
||||
- `${var:=default}`
|
||||
- `${var:-default}`

||||
