Hello,
I want to take the contents of my current file as input, send it through a series of pipes (using sed and awk to fix mistakes) and replace the contents with the output of the pipes. What’s the best way to do this?
Example file:
My apointment is tomorow.
I want to run the command
sed ‘s/apointment/appointment/’ | sed ‘s/tomorow/tomorrow/’
To get the output
My appointment is tomorrow.
You can write a plugin that will, for example, take a command line to execute, send the contents of the current buffer (or current selection) to the command line, and replace the buffer or selection with the output.
Does that mean I have to learn Python? In Textmate is was as easy as point and click.
So, I’m trying something like this, but I can’t get it to work
import sublime, sublime_plugin
import subprocess
"""
Runs an external command with the selected text,
which will then be replaced by the command output.
"""
class ExternalCommand(sublime_plugin.TextCommand):
def run(self, edit, args):
# nothing selected: process the entire file
region = sublime.Region(0L, self.view.size())
p = subprocess.Popen(
args,
shell = True,
bufsize = -1,
stdout = subprocess.PIPE,
stderr = subprocess.PIPE,
stdin = subprocess.PIPE)
output, error = p.communicate(self.view.substr(region).encode('utf-8'))
if error:
sublime.errorMessage(error.decode('utf-8'))
else:
edit.replace(region, output.decode('utf-8'))[quote=“nachocab”]So, I’m trying something like this, but I can’t get it to work
edit.replace(region, output.decode('utf-8'))
[/quote]
You aren’t calling replace correctly, it’s a View method. There should have been an error message in the console. Try:
self.view.replace(edit, region, output.decode('utf-8'))When I do that, sublime crashes and I don’t know how to fix it because I can’t see the error message. Is there a way to debug this? I’m pretty new at this.
I found this post when searching google to find out how to apply a unix command to a selection in sublime and it provided a great start for a solution. Here is a version of the original code that does the job. It’d be great if sublime could have a similar feature built in or this command bundled.
To use it, select some text and then from the console enter “view.run_command(‘external_filter’)”, sublime will prompt you for a command, enter a valid unix command and it will pipe your selection through the command and replace the text with it’s output.
import sublime
import sublime_plugin
import subprocess
# view.run_command('external_filter')
class ExternalFilterCommand(sublime_plugin.TextCommand):
def run(self, edit):
self.view.window().show_input_panel('Command', '',
lambda command: self.runCommand(edit, command),
None, None)
def runCommand(self, edit, command):
regions = self.view.sel()
if len(regions) == 1 and regions[0].empty():
# No selection use the entire buffer
regions = [sublime.Region(0, self.view.size())]
for region in regions:
self.execCommand(edit, command, region)
def execCommand(self, edit, command, region):
p = subprocess.Popen(command, shell=True, bufsize=-1,
stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)
output, error = p.communicate(self.view.substr(region).encode('utf-8'))
if error:
sublime.error_message(error.decode('utf-8'))
else:
self.view.replace(edit, region, output.decode('utf-8'))This just needs to be included in the default distribution.
Select buffer, press hotkey, prompt for command, replace buffer with command output.
