Mise à jour du 24 février 2017 : l'indicateur dispose désormais d'une option pour épingler les liens Web
introduction
REMARQUE: La version précédente de cette réponse se trouve dans l'historique des modifications, bien qu'elle ne soit plus pertinente.
L'indicateur présenté ci-dessous a été conçu pour une question différente, mais depuis que l'opportunité s'est présentée, j'ai décidé de le publier ici. L'indicateur de fichiers est un indicateur simple pour accéder aux fichiers et dossiers de l'utilisateur. Il permet de vérifier les fichiers récemment utilisés, les fichiers de signets et les répertoires. En particulier, le menu Lieux est spécifiquement pertinent pour cette question.
Comme vous pouvez le voir sur la capture d'écran, l'indicateur prend également en charge des paramètres régionaux autres que l'anglais, donc si votre système utilise autre chose que l'anglais, cela fonctionnera.
Mise à jour : l'indicateur prend désormais également en charge le lancement de fichiers .desktop qui ont été épinglés. Par exemple, si vous avez épinglé firefox.desktop, il lancera firefox. Ainsi, l'indicateur peut être utilisé comme lanceur rapide pour les programmes. La fonctionnalité est en cours d'entrée dans PPA au moment de la rédaction (19 novembre, 19h53 GMT, devrait prendre environ 24 heures pour être traitée), mais est déjà sur github ainsi qu'ici, dans le code source mis à jour.
Obtention de l'indicateur
L'indicateur est disponible sur mon PPA personnel ainsi que sur GitHub . Utilisez les étapes suivantes pour l'obtenir:
sudo add-apt-repository ppa:1047481448-2/sergkolo
sudo apt-get update
sudo apt-get install files-indicator

Configurations
L'indicateur est configuré via deux fichiers json stockés dans le répertoire personnel de l'utilisateur.
~/.files_indicator.json contrôle l'interface utilisateur, la longueur des entrées de menu et le nombre maximum dans le menu Fichiers récents.
{
"name_length": 30,
"max_items": 10
}
Le ~/.pinned_files.jsoncontrôle les listes des fichiers et dossiers épinglés. Chaque élément est une liste / un tableau.
{
"dirs": [
"/home/xieerqi/\u56fe\u7247/Wallpapers"
],
"files": [
"/home/xieerqi/work_in_progress/videonauth_code.py",
"/home/xieerqi/work_in_progress/spin_button.py"
