SublimeText可以在无须将文件存盘、保存更改的情况下将软件关闭，而不丢失会话状态，我养成了打开N个文件的习惯，其中很多都是未存盘的、未保存更改的；想要清理的时候发现不能方便地判断一些处于“未保存”状态的文件是否已被删除，所以写了个小插件，在状态栏显示已打开多少个文件，以及当前文件的具体状态：未存盘、已删除、已保存、未保存。
效果预览：
显示格式为[当前window打开的文件数量 ~ 文件状态]，SAVED / UNSAVED / NONE / DEL 分别代表已保存、文件存在但未保存更改、文件不再盘上、文件之前在盘上但已被删除。当然，格式和代号你可以根据喜好修改。
本文插件以及更多插件已在github开源，此repo中还有表格转换、html处理、时间转换等一些小工具，欢迎使用、反馈。
实现方案
在SublimeText3\Data\Packages\User\目录下新建show_file_status.py文件，内容如下：
import os.path
import sublime
import sublime_plugin
class ShowFileStatus(sublime_plugin.EventListener):
def update_file_status(self, view):
if not view.file_name():
status = "NONE"
elif not os.path.exists(view.file_name()):
status = "DEL"
elif view.is_dirty():
status = "UNSAVED"
else:
status = "SAVED"
window = sublime.active_window()
status = str(len(window.views())) + " ~ " + status
view.set_status(self.KEY_SIZE, "[%s]" % status)
on_post_save_async = update_file_status
on_modified_async = update_file_status
on_activated_async = update_file_status
另一种方案：
官方repo中的StatusBarFileSize这个package可以在状态栏显示当前文件的体积，它是结合文件编码进行计算的，稍微有一点耗性能，如果你需要它提供的这个功能的话，可在安装完成后，参考下面的代码进行一些修改，也可以实现本文主题的功能。
效果预览：
安装完毕后，替换SublimeText3\Data\Packages\StatusBarFileSize\下的StatusBarFileSize.py为以下内容：
import os.path
import sublime
import sublime_plugin
# Format a size in bytes into a nicer string value. Defaults to 1024 convention.
def file_size_str(size, divisor=1024):
sizes = ["KiB", "MiB", "GiB", "TiB", "PiB", "EiB", "ZiB", "YiB"]
if size = divisor:
size_val /= divisor
else:
return "%.2f %s" % (size_val, unit)
return "%.2f %s" % (size_val * divisor, sizes[-1])
# Far from a perfect system, but seems to be the only way to get a usable Python
