Re: Ranger, a textbased filemanager

Another key binding which should show up in the options at the bottom:  Pressing "p" shows the options "p once again" and "l".  The option "o" should also  show up.

Hm right, gonna add that

Hi I saw that tagging was only there as a reminder. But is there a way to tag or select files in different directories, so I could move them altogether in another one ?

As far as I know, this is not possible with the current version of ranger.
The tagged files are saved in ~/.ranger/tagged. You can easily write a script to move them all to one directory.
If none of the files contain spaces, this can be done with

cat ~/.ranger/tagged | xargs mv -t /the/target/directory

If they have spaces, I think you will have to work with readline.

I think that the bug is that the module name is OptionParser

Yeah that's just a typo, sorry for not testing before uploading the changes

I have upgraded Ranger to the most recent version with git, and if I add this code to the beginning of ~/.ranger/apps.py and run rvimtest on the file nothing happens. I have to run rvim to open the file, but it opens in the same window. If I add the code to /usr/lib/python2.6/site-packages/ranger/defaults/apps.py I get this traceback error and ranger
will not start:

Fatal: cannot import name CustomApplications
A traceback has been saved to /home/jostein/.ranger/traceback
Please include it in a bugreport.

You can't put the same code in your ranger/defaults/apps.py.
In fact, the code in ~/.ranger/apps.py refers to your ranger/defaults/apps.py, in the line "from ranger.defaults.apps import ..."

Instead, just add the function (app_vimtest) without the first few lines to the existing class (CustomApplications in ranger/default/apps.py).

I still wonder why your ~/.ranger/apps.py is not working. Can you tell me what operating system/linux distro and python version you are using? Can you post the exact content of ~/.ranger/apps.py again?

Re: Ranger, a textbased filemanager

My operating system is Suse 11.2 and I use Python 2.6.2. Here is my complete ~/.ranger/apps.py:

This is the default ranger configuration file for filetype detection
and application handling.

You can place this file in your ~/.ranger/ directory and it will be used
instead of this one.  Though, to minimize your effort when upgrading ranger,
you may want to subclass CustomApplications rather than making a full copy.
           
This example modifies the behaviour of "feh" and adds a custom media player:

    from ranger.api.apps import *

        def app_feh_fullscreen_by_default(self, c):
            return tup('feh', '-F', *c)

        def app_default(self, c):

Re: Ranger, a textbased filemanager

The reason is: after you define CustomApplications, you define it again, overriding your custom version with the default version.

Change the content to only:

from ranger.defaults.apps import CustomApplications as DefaultApps
from ranger.api.apps import *
class CustomApplications(DefaultApps):
    def app_vim(self, c):
            return tup("screen", "-t", c.file.basename, "vim", *c)

Re: Ranger, a textbased filemanager

Hello, first of all, thanks a lot for your great program! Been looking for a file manager with Miller columns for a while (found Dolphin, GWorkspace, a 4 years old Thunar hack... neither really did the work for me) and Ranger is definitely the most promising. Umm, I do have a couple suggestions - some of which have been mentioned already and I wasn't able to find solutions in the thread, so apologies if they have been addressed already!

1. Lazy horizontal scrolling? I must admit, it does feel a little weird when I click on the second column and it becomes the 2nd-to-last column, in my case at least. I'm no programmer, but from what I have gathered, it might require abandoning the 'second to last column = active' mechanism... so I guess I understand if you don't want to tackle it.

2. Custom "preview" for non-text files? As someone suggested, mediainfo, perhaps file - or set it just like you do with default applications in apps.py.

Re: Ranger, a textbased filemanager

If I delete everything in ~/.ranger/apps.py and enter the code above, as well as entering the two last lines in ranger/default/apps.py it now works, but only if I use "rvim" on the file. It does not work when using Return on the file.

Should I delete everything except the code above in local apps.py or are there specific lines that should be deleted?

A look at app_default makes me think that you have to explicitly make this new function your default editor:

from ranger.defaults.apps import CustomApplications as DefaultApps
from ranger.api.apps import *
class CustomApplications(DefaultApps):
    def app_vim(self, c):
            return tup("screen", "-t", c.file.basename, "vim", *c)
    app_editor = app_vim

I thought about it for a while. It is indeed a little unusual that the thing you just clicked on suddenly moves away. But when using the keyboard, this doesn't bother me. So I won't work on that in the near future, though I'd accept patches.

2. Custom "preview" for non-text files? As someone suggested, mediainfo, perhaps file - or set it just like you do with default applications in apps.py.

Somebody already hacked in previews for images using libcaca. (It's also available on the caca branch of my git repo.)
It won't be too hard to add a mediainfo preview too.

Yet, how about a simple string option: you could set it to the path of an executable script which takes the filename as an argument and prints a preview to the stdout. This would override rangers default preview with whatever you like. Such a script would look like:

#!/bin/bash
type="$(file -Lb --mime-type "$1" | grep -o '^[^/]\+')"
case $type in
    text )
        cat "$1" ;;
    image )
        <some caca preview> "$1" ;;
    video )
        mediainfo-something "$1" ;;
esac

Re: Ranger, a textbased filemanager

May I ask what the definitive code would be for tmux. For, opening a text file in a new tmux 'pane' -- same window though, -- a new pane in the tmux window that tmux runs ranger in.  Hoping I just got it wrong on earlier attempts of there was an imcompatibility that may now be resolved. No concern of course if it doesn't happen for me for a while as things are great enough as they are. Would be cool to have a text file open up in a new pane with vim and have ranger still viewable in same window beside it. I use urxvtc.

The reason is: after you define CustomApplications, you define it again, overriding your custom version with the default version.

Change the content to only:
Code:

from ranger.defaults.apps import CustomApplications as DefaultApps
from ranger.api.apps import *
class CustomApplications(DefaultApps):
    def app_vim(self, c):
            return tup("screen", "-t", c.file.basename, "vim", *c)

Re: Ranger, a textbased filemanager

yvonney: That depends on what exactly you want.
Split the window vertically or horizontally?
Always do it whenever you open a file in vim? Or just as a new mode, to use with eg. 2<Enter>?
What should happen if you select multiple files and press enter?

Re: Ranger, a textbased filemanager

from ranger.api.apps import *
class CustomApplications(DefaultApps):
    def app_editor(self, c):
        if 'TMUX' in os.environ:
            from ranger.ext.shell_escape import shell_escape
            return tup("tmux", "split-window", "-h",
                    "vim " + "".join(shell_escape(name) for name in c))
        else:
            return DefaultApps.app_vim(self, c)

This looks reasonable.
If you're in tmux, it opens vim in a new "sidebar", otherwise it just runs vim normally.
If  you want a vertical split instead, change the "-h" to "-v".

Re: Ranger, a textbased filemanager

That is amazing. Put the above code in apps.py deleted apps.pyo just in case. killed and restarted tmux/ranger et al.

now simply by hitting return on a file that ranger understands as vim-open-able and a pane opens up beside ranger.
This is SO amazingly useful for my requirements. I really like that after thinking with it for a few days it's cooler that it happened today!
Also thinking that add-on files like apps.py are great as ranger can stay lean.

Thanks for all your help on this.

Re: Ranger, a textbased filemanager

Ranger is some great file manager, really like the design of this. I have a couple of questions:

1. Is there a 'screen' mode so you can open a file in a new screen window instead of the same window as Ranger?
2. If I choose to open an image file in a directory, Ranger opens all images in that directory with the same file ending in feh. Should this be so?

I solved pt.2 by commenting out the first line in apps.py, and entered the second line below instead:

# images = [f.path for f in directory.files if f.image]
  images = f.path

Re: Ranger, a textbased filemanager

Btw, that is fixed in the newest version already.

I improved my zle widget for ranger integration:

integrate_ranger()
{
    local before="$(pwd)"
    ranger $before <$TTY
    local after="$(grep \^\' ~/.ranger/bookmarks)"
    after[1,2]=
    if [[ $before != $after ]]; then
        cd $after
        print "ranger: $before -> $after"
    fi
    zle redisplay
    precmd
}

*steals some ideas for own .bashrc*
EDIT:
Sure that this doesn't break when either path contains spaces?
I'd put "" around each $before and $after (except in the print)

This is what I use to view the directory, starting at the selected image:

[~/.ranger/apps.py]

class CustomApplications(DefaultApps):
        def app_feh(self, c):
                cwd = self.fm.env.cwd.path
                return tup('feh', cwd, '--start-at', *c)

        def app_default(self, c):
                f = c.file #shortcut
                if f.image:
                        return self.app_feh(c)

                return DefaultApps.app_default(self, c)

Nice, didn't know of the --start-at option of feh. (and that you can view whole directories easily.) This makes things much easier

No, zsh doesn't split words on variable expansion unless SH_WORD_SPLIT is set. SH_WORD_SPLIT can be set temporarily by using $=foo instead of $foo, but in most cases it's better to use an array, they are far more powerful.

Re: Ranger, a textbased filemanager

Information about the progress:

1. I'm implementing easily extendable previews. Ranger will just call an external program, pass the filename as an argument and use its output as the preview. That program can call stuff like img2txt, highlight, pygmentize, mediainfo or whatever you want. It would look similar to the apps.py, but you would require no knowledge of ranger internals to edit it since it runs independently.
2. A contributor is trying to get directories loading faster by rewriting the related functions. Let's see how far this gets. I still hope ranger will be as fast as vifm some day
3. I want to make configuration files more simple. Throw in your suggestions!

Re: Ranger, a textbased filemanager

Nice, especially 2. The slow directory loading is my biggest problem with ranger.

1. Adhere to the unix philosophy and "do one thing but do it well"
=> Ranger is a file manager, not a file launcher.
Remove apps.py, leave launching of programs to another program.

I strongly agree. It would be great to write a script that takes a file as an argument and opens it with the correct program based on mime type and make all my programs use that script.

Re: Ranger, a textbased filemanager

A little off-topic: I would very much like to replace vim's internal file explorer with ranger. Does anyone know if there is a way to do that?

Re: Ranger, a textbased filemanager

I agree about removing apps.py as well - imo ranger should honor the existing mimetype associations. Maybe ranger should require xyne's mimeo.

@Franek, yeah that would be awesome. Vim can be scripted with python, so it should be possible. You might want to check out nerdtree.

Re: Ranger, a textbased filemanager

@vim integration:
No idea, but I doubt that it's trivial :-)
I'll be there for consulting if someone wants to try it.

It's worth hundreds of beers. Hopefully Ranger isn't released under a beerware license!

Re: Ranger, a textbased filemanager

Version 1.1.0 (stable) is out.
For those who regularily updated: this is nothing new, just what you've been testing all along.
For those who didn't: consider upgrading now =P

Re: Ranger, a textbased filemanager

Anyone think of a way to change the PS1 to indicate that the shell was started from within Ranger (via 'S') ? I find myself entering the shell for a bit, walking away for awhile and then inadvertently starting a second ranger instance instead of C-d to get back to the first one.

Thanks!

Re: Ranger, a textbased filemanager

make Ranger's S set os.environ['PS1'], and make your shell rc a) not set PS1 if it's already set or b) append to it
