我正在尝试为Sublime编写一个插件,它将读取当前行的文本,将其作为shell命令执行,并将命令的输出放入编辑器中。这就是我到目前为止所做的:
import sublime, sublime_plugin, os, os.path
import subprocess
def GetLineAtCursor(view):
pos = view.sel()[0].a
reg = view.line(pos)
return view.substr(reg)
class ExecuteLineGetOutputCommand(sublime_plugin.TextCommand):
def run(self, edit):
line = GetLineAtCursor(self.view).strip().split()
output = subprocess.check_output(line,shell=True)
self.view.insert(edit, 0, output)
这不起作用。具体来说,对subprocess.check_output(...)
的调用不起作用,尽管它在python解释器中工作正常。我把它放在一个试块中,像这样:
try:
output = subprocess.check_output(line,shell=True)
except Exception as e:
self.view.insert(edit, 0, str(e))
它产生以下输出,似乎无论我尝试什么命令:
[WinError 6] The handle is invalid
有人知道问题是什么,以及如何解决?
答案 0 :(得分:1)
试试这个:
def run(self, edit):
line = GetLineAtCursor(self.view).strip().split()
cmd = [line, 'attr1', 'attr2']
# if windows
p = subprocess.Popen(cmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, startupinfo=startupinfo, shell=False, creationflags=subprocess.SW_HIDE)
#else unix/macos
p = subprocess.Popen(cmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
output, stderr = p.communicate()
if (stderr):
print(stderr)
self.view.insert(edit, 0, output)
