Re: Ranger, a textbased filemanager

Anyone experienced that "slowness" of Ranger after some time of use without restarting it? I use Ranger in a way that it's opened 24/7, for days, and by time it gets slow while accessing bookmarks, folders and sort of...The thing gets solved when I restart it (or X, which is more often).
Any thoughts on this?

Re: Ranger, a textbased filemanager

Already had it running for weeks (with laptop suspended over night) and everything was fine.

Did you notice an increase of memory usage?

I will be testing it. it's 0.9% now and it's performing nice.

Re: Ranger, a textbased filemanager

It is now at 1.2% memory usage and I start to feel the slower processing (when picking different bookmarks only, though).

Re: Ranger, a textbased filemanager

Can you please type in the following key sequence and see if it gets better?

oror otob zdzd zszs zhzh

without the spaces. This should clean up the hooks of garbage collected directories.

EDIT: or just update and restart ranger, I patched it.
Dunno if this was the primary cause for the slowdown though.

Re: Ranger, a textbased filemanager

Ok, I'll be testing the latest version. It definitely gets faster when I restart Ranger.

Re: Ranger, a textbased filemanager

Hey,

Is there list of all keybinding contexts? I skimmed the pydoc docs, but couldn't find anything (I'm also not familiar with python, so there).

Also, some other things:

1. I'm using a non-QWERTZ keyboard layout (NEO) and need to redefine some keybindings and aliases (main issue: hjkl is now snrt). However, when I tried the open_with command, I couldn't type the snrt keys, because they worked like the arrow keys. This is my keys.py:

from ranger.api.keys import *

# Browser keybindings
map = keymanager.get_context('browser')
map('<C-D>', fm.move(down=0.5, pages=True))
map('<C-U>', fm.move(up=0.5, pages=True))
map('N', fm.history_go(-1))
map('R', fm.history_go(1))
map('t', fm.tag_toggle())
map('T', fm.tag_remove())
#map('S', fm.execute_command(os.environ['SHELL']))
map('.', fm.search())
map(',', fm.search(forward=False))
map('Y', fm.open_console('open_with '))

# Pager keybindings
map = keymanager.get_context('pager')
map('<left>', 's', wdg.move(left=4))
map('<right>', 't', wdg.move(right=4))

# Taskview keybindings
map = keymanager.get_context('taskview')
map('R', wdg.task_move(0))
map('N', wdg.task_move(-1))

# Global keybindings
map = KeyMapWithDirections()
map('n', alias='<down>')
map('r', alias='<up>')
map('s', alias='<left>')
map('t', alias='<right>')

keymanager.merge_all(map)

Redefining the keys in the browser instead of the global context makes them work, but I'm wondering if I'm missing something here—are those keys used in some other context I'm not (yet) aware of?

2. What is the proper way to define global bindings before contextual ones without messing up the config? Again, I'm not familiar with Python. Not at all.

3. Is there a way to delete default keybindings? (I'd like to delete the default hjkl aliases, for example).

Hi,

1. The contexts are here:
http://nongnu.org/ranger/pydoc/ranger.c … nment.html
Easy to miss, they're at the very bottom

2. You just merge them in. If you don't want to merge in snrt into the console context, do this:

map = KeyMapWithDirections()
map('n', alias='<down>')
map('r', alias='<up>')
map('s', alias='<left>')
map('t', alias='<right>')

for context in ["browser", "pager", ...]:
    keymanager.get_context(context).directions.merge(map)

rather than merge_all
Not sure if this works but it should give you the idea.

Note that there's a difference between normal mappings and direction mappings. It even confuses myself, and I'm already working on a more simple interface for creating keybindings, similar to a .vimrc

3. There's unmap:

for context in ["browser", "pager", ...]:
   keymanager.get_context(context).unmap('x')
   keymanager.get_context(context).directions.unmap('j')

Re: Ranger, a textbased filemanager

Hi, I have a couple of questions. I want to be able to do the following things:

- Spawn a new terminal at the cwd
- Run a command in such a way that I can see the output, but that I can continue doing other stuff in ranger. For example, if I run unrar on a very large file, I want to be able to see the progress but it in the meanwhile continue with ranger. I tried using the pager, but I didn't find a way of hiding and showing the pager at will.

- A while ago I asked about the incremental search. It is working ok, but when I have found the file and press enter to leave the search, ranger jumps to the next item. I have to press escape instead of enter to kill the search prompt. How can I make enter do the same?

Thanks!

Re: Ranger, a textbased filemanager

1. the command :terminal runs the program x-terminal-emulator, link this to your favourite terminal emulator or edit the command.
You can also type @urxvt<enter> or something.
2. Better open a new terminal for this. I may implement it in the future though.
3. This sounds ilke a bug

Re: Ranger, a textbased filemanager

Ok, thanks! I have another quick question A while ago I asked for a delete function that deletes things right away. This was the answer:

map(383, fm.open_console('delete y'))

This works, but I still need to press enter. How can I make this command get executed right away?

Re: Ranger, a textbased filemanager

use execute_console instead of open_console
you can also try this one:
map(383, fm.execute_console("shell -d rm %s"))
this runs "rm" on all selected files in the background and doesn't block the terminal if you delete a lot at once

Very nice and interesting, I use this one as my main fm instead of vifm

Re: Ranger, a textbased filemanager

Any way I can recover deleted files with a ":delete" command? I've tried using lsof, but it doesn't see it...

Re: Ranger, a textbased filemanager

Ok, nvm, since I found that the file I accidentally deleted (a "conkeror.install" file that's needed in my custom conkeror package) wasn't actually needed at all.

This doesn't seem to work. fm.execute('delete y') does work, however.

I remembered that this incremental search was a custom thing. Can you give me the code of the command or tell me the changes you made?

Also, when you say it "jumps to the next item", do you mean it goes down or right?

Re: Ranger, a textbased filemanager

The code is:

class inc_search(search):
  def quick(self):
    if self.line.split(" ", 2)[1]:
      search.execute(self)

When I say jump to the next item, I mean a jump to the next item that fits the search query.

Re: Ranger, a textbased filemanager

Hi hut,

I switched to ranger recently. Now I'm using "ranger-git". Basically, it works fine, but after I edited a file and back to ranger, it seems get no reflect about the modified file. does ranger have the ability to track file modification?

thanks.

Re: Ranger, a textbased filemanager

class inc_search(search):
  def quick(self):
    if self.line.split(" ", 2)[1]:
      search.execute(self)

When I say jump to the next item, I mean a jump to the next item that fits the search query.

It's no bug after all. It's a flaw in the command. Since inc_search is a subclass of the search command, which does a search when you press enter, this command will also do a search when you press enter.
Try this one:

class inc_search(Command):
    def quick(self):
        split = self.line.split(" ", 2)
        if len(split) > 1 and split[1]:
            self.fm.search_file(split[1], regexp=True)

It also avoids that "list index out of range" error message, perhaps you've noticed it

Here's an alternative; it doesn't jump to the next matching file if the current file is still matching:

class inc_search(Command):
    def quick(self):
        import re
        split = self.line.split(" ", 2)
        if len(split) > 1 and split[1] and not re.match(split[1], self.fm.env.cf.basename):
            self.fm.search_file(split[1], regexp=True)

Hi hut,

I switched to ranger recently. Now I'm using "ranger-git". Basically, it works fine, but after I edited a file and back to ranger, it seems get no reflect about the modified file. does ranger have the ability to track file modification?

(edit typo)

New versions of ranger never update previews, unless you press <Ctrl-R> or (under certain conditions) resize the window.
This will be fixed at some point... perhaps now.
Edit: done

Re: Ranger, a textbased filemanager

Thanks hut, it's working now Wouldn't this be a nice feature to add by default? I think it is one of the quickest ways to navigate through large directories.
