Perbarui Feb / 24/2017 : indikator sekarang memiliki opsi untuk menyematkan tautan web
pengantar
CATATAN: Versi sebelumnya dari jawaban ini dapat ditemukan di bawah riwayat edit, meskipun tidak lagi relevan.
Indikator yang disajikan di bawah ini dimaksudkan untuk pertanyaan yang berbeda, tetapi karena kesempatan muncul dengan sendirinya, saya memutuskan untuk merilisnya di sini. Indikator File adalah indikator sederhana untuk mengakses file dan folder pengguna. Ini memungkinkan memeriksa file yang terakhir digunakan, mem-bookmark file dan direktori. Secara khusus, menu Places secara khusus relevan dengan pertanyaan ini.
Seperti yang dapat Anda lihat dari tangkapan layar, indikator ini juga mendukung lokal selain bahasa Inggris, jadi jika sistem Anda menggunakan sesuatu selain bahasa Inggris, itu akan berfungsi.
Perbarui : indikator sekarang juga mendukung meluncurkan file .desktop yang telah disematkan. Sebagai contoh jika Anda memiliki pin firefox.desktop, itu akan meluncurkan firefox. Dengan demikian, indikator dapat digunakan sebagai peluncur cepat untuk program. Fitur sedang dalam perjalanan ke PPA pada saat penulisan (19 Nov, 19:53 GMT, harus memakan waktu sekitar 24 jam untuk diproses), tetapi sudah ada di github dan juga di sini, dalam kode sumber yang diperbarui.
Memperoleh indikator
Indikator tersedia dari PPA pribadi saya dan juga GitHub . Gunakan langkah-langkah berikut untuk mendapatkannya:
sudo add-apt-repository ppa:1047481448-2/sergkolo
sudo apt-get update
sudo apt-get install files-indicator

Konfigurasi
Indikator dikonfigurasikan melalui dua file json yang disimpan dalam direktori home pengguna.
~/.files_indicator.json mengontrol antarmuka pengguna, panjang entri menu dan jumlah maksimum di Menu File Terbaru.
{
"name_length": 30,
"max_items": 10
}
The ~/.pinned_files.jsonmengontrol daftar file dan folder disematkan. Setiap item adalah daftar / larik.
{
"dirs": [
"/home/xieerqi/\u56fe\u7247/Wallpapers"
],
"files": [
"/home/xieerqi/work_in_progress/videonauth_code.py",
"/home/xieerqi/work_in_progress/spin_button.py"
]
}
]
