在 awesome 中,图片浏览器 qiv 好在不用作任何额外设置,就能居中显示,但是我就是
没有办法让 feh 也能在 awesome 中自动居中显示。
ranger 默认使用 feh 打开图片文件,不过可以自定义文件打开方式,编辑/新建
~/.config/ranger/apps.py,加入下列代码:
from ranger.defaults.apps import CustomApplications as DefaultApps
from ranger.api.apps import *
class CustomApplications(DefaultApps):
def app_qiv(self, c):
f = c.file
if f.image:
return self.either(c, 'qiv')
@depends_on('qiv')
def app_feh(self, c):
arg = {1: '-z', 2: '-y', 3: '-x'}
c.flags += 'd'
if c.mode in arg: # mode 1, 2 and 3 will set the image as the background
return tup('qiv', arg[c.mode], c.file.path)
if c.mode is 11 and len(c.files) is 1: # view all files in the cwd
images = (f.basename for f in self.fm.env.cwd.files if f.image)
return tup('qiv', *images)
return tup('qiv', *c)
