Comment définir ce paramètre dans les fichiers de construction?Comment définir maxPrintString dans les fichiers de construction
Dans le REPL, il peut être fait avec les commandes ci-dessous, mais je veux éviter de faire que chaque fois que je commence la console:
:power
vals.isettings.maxPrintString = 10000
[email protected]:~$ scala

Edit: la valeur semble inclure le res0: String = partie.
En outre, puisque vous avez dit fichier de construction, je remarquais cela ne fonctionne pas:

$intp.isettings.maxPrintString: Int = 2000
Je rappelle que SBT évalue initialCommands tôt, apparemment avant REPL a une chance de se lier $intp.
Mais cela fonctionne:

Pas comme Croquignolettes, mais vous pourriez peut-être redéfinir la tâche de la console et définir la propriété que @ som-snytt parlait.
val initializeMaxPrintString = taskKey[String]("Initialize scala.repl.maxprintstring")
initializeMaxPrintString := {
sys props "scala.repl.maxprintstring" = "10000"
}
console in Compile := (console in Compile dependsOn initializeMaxPrintString).value
console in Compile := {
val c = (console in Compile).value
sys.props remove "scala.repl.maxprintstring"
c
}
L'inconvénient est le même que pour la réponse @ som-snytt, le res0: String = seront pris en compte dans.
Scala way 'sys les accessoires" scala.repl.maxprintstring "=" 10000 "' et 'sys.props suppriment" scala.repl.maxprintstring "'. –
@ som-snytt merci, je dois admettre que je ne savais pas cela, j'ai mis à jour ma réponse. – lpiepiora

Je veux mettre cela dans les fichiers de construction pour être en mesure de lancer le REPL avec 'SBT console' (pour avoir des dépendances configurées), donc votre première solution ne convient pas à mes besoins. –
@YannMoisan Eh bien, vous pouvez le passer à sbt, voir mise à jour. –
