Re: Ranger, a textbased filemanager

A VFS for archives would be fantastic. I have no idea how hard that is to implement.

Agree! Transparent archive navigation is very handy. But at some cases we need just to unpack an archive into a given destination (which will be much faster rather via vfs).

As for unpacking in a ranger-way I imagine something like additional copy/paste commands (yz/pz?). Password-protected archives must invoke console dialog (one by one) with password prompt. Something similar can be imagined wrt creating new archive (with prompt for new archive name and autodetection pack command on file extension base).

Re: Ranger, a textbased filemanager

did you know you can open archives with vim? AFAICT that should be all you need.

Re: Ranger, a textbased filemanager

I got no problem with password-protected archives (except with certain rar version), and I didn't use atools for my archive preview because it's much slower than 7z.

Re: Ranger, a textbased filemanager

I got no problem with password-protected archives (except with certain rar version), and I didn't use atools for my archive preview because it's much slower than 7z.

For protected rar archives I have added

case "$extension" in
    # RAR extension (reports error for passworded archives):
    rar)
        unrar l -p- "$path" 2>&1 | head -n $maxln && exit 3
        exit 1;;

into the scope.sh script.

What is your scenario wrt unpacking archives (being they password-protected or not) inside ranger?

Re: Ranger, a textbased filemanager

Lately the password-protected rar I got using format like this (and I got no problem with it, a few days ago)

*.part1.rar
*.part2.rar
...

but not with format (IIRC) like this (I didn't have this type anymore because I already convert it to zip)

*.rar
*.r00
*.r01
...

and I replace default preview application (atool -l) with 7z (because I still need 7z)

7z l "$path" | head -n $maxln && exit 3
exit 1;;

Re: Ranger, a textbased filemanager

@igndenok

The thing is, it is insignificant for me which multivolume rar format to use (I don't use rar as packer at all). But, say, respondents can sent a message with this ot that format, and it would be handy to deal with all of them.

As for previewing - at case a rar archive is password protected, all tools (7z, unrar, atool) prints prompt for password and waits for something to be typed in stdinput. At my case it results in ranger hang. So, take especial  attention to '-p-' option in 'unrar l -p- "$path" 2>&1 | head -n $maxln && exit 3'. This way ranger hangs problem is eliminated for me.

Re: Ranger, a textbased filemanager

I didn't read unrar help, thanks for pointing that out. It seems that 7z can list directly password-protected rar without problem, assuming it was rar version 3. I think I'll use your method as fallback.

You can then bind a key to the :extracthere and :compress commands (I use px and pc).

There are two type of password protecting - content only, and both content and header. At last case 7z (as well as any other listed tool) will wait for password from stdin.

Re: Ranger, a textbased filemanager

What is a common way to deal with archives? I mean we want to stay in text mode. And let's imagine simple case when an archive isn't password-protected. So, we have /very/long/and/deep/source/path/someArchiveNameWithSpaces.tar.bz2 and /even/more/deep/and/long/destination/path. How does ranger help here?

I'd probably use: 1lccdd <navigate to destination> pp

As for vfs, it's planned but in the meantime you can just open the archive in vim ?

It's likely fixed in ranger-git already, try it and report ?
Also, can you share your lines in scope.sh?

Here my scope.sh

Edit: My new scope.sh, I got less problem with this new config.

Thanks, it does work. I haven't used aunpack earlier and, as a result, didn't know aunpack will create a dedicated dir if needed.

Re: Ranger, a textbased filemanager

Let me know if you find that leak or need me to test it more some how. It still does it-- both on my bfs patched kernel and vanilla kernel. I don't think the problem is on my configuration or anything.

Re: Ranger, a textbased filemanager

Here is a little function to move forward and backward by a word in console mode :

    # add it to ranger/gui/widgets/console.py
    def move_by_word(self, forward=True):
        if self.line:
            self.tab_deque = None
            if forward:
                i = self.pos + 1
                if i >= len(self.line):
                    return
                while i < len(self.line) and re.match(r'[\w\d]', self.line[i], re.U):
                    i += 1
            else:
                i = self.pos - 1
                if i <= 0:
                    return
                while i > 0 and re.match(r'[\w\d]', self.line[i-1], re.U):
                    i -= 1
            self.pos = i
            self.on_line_change()

I noticed that when <A-something> is mapped in console mode, pressing Escape doesn't quit this mode.

Re: Ranger, a textbased filemanager

Fiew tiny suggestions:

1. For current tab highlighting use inversed colors wrt others tabs (as for files/directories highlighted row).
2. Show seconds also in file's date-time - (status line, left bottom corner).
3. Show yy/dd state, say dd:5 which means five items (files and/or dirs) are dd-ed - (status line, right bottom corner)

What do you think?

Re: Ranger, a textbased filemanager

Hello.
I have two things to propose.

Make the hints more verbose (I hardly remember some shortcuts I rarely use )
But I know some lines are too longs (like those for goto and options)

for y<bg>:
copy: copy add remove path_to_xsel dirpath_to_xsel basename_to_xsel

for d<bg>:
disk_usage cut: d:cut add remove
instead of
du (disk usage) dd (cut)

for p<bg>:
paste: paste overwrite symlinks relative_symLinks
instead of
press p to confirm pasting, overwrite, create symlinks, relative symLinks

for z<bg>:
filter options: directories_first collape_preview sort_case_insensitive show_hidden preview_files Preview_dirs use_preview_script flushinput mouse
instead of
[cdfhimpPsv] show_hidden preview_files Preview_dirs filter flushinput mouse

for o<bg>:
sort by: size basename mtime type reverse natural
instead of
size basename mtime type reverse natural

for g<bg>:
goto: / dev etc h:~ media Mnt opt srv usr var Ranger link: l:target_path reaL_path tab: close new next T:prev

for c<bg>:
w:rename chdir search order: ctime mimetype size tag
instead of
ctime mimetype size tag  w:rename

when displaying the taskview (w):
tasks: dd:remove J:move_down H:move_up

patch: http://pastebin.archlinux.fr/pastebin.php?dl=432299

A view to display the list of files currently in copy buffer (so we can remove them one by one).
patch: http://pastebin.archlinux.fr/pastebin.php?dl=432298

Probably :delete will be more consistent if it will ask a conformation at any case.

Re: Ranger, a textbased filemanager

Hello!
Is there any chance to get aliases and hashes (hash -d) from ~/.zshrc worked with ranger?

Also, found an issue whith command :shell cp %s %D an error 'NoneType' object has no attribute 'path' appears if destination directory is empty.

Re: Ranger, a textbased filemanager

@loop: you can add this to your file ~/.config/ranger/keys.py (create it if necessary) :

from ranger.ext.spawn import spawn
from ranger.fsobject import Directory
import re

class hash_to_bookmarks(Command):
    def tab(self):
        return ['hash_to_bookmarks force']

    def execute(self):
        line = parse(self.line)
        lastword = line.chunk(-1)
        force = lastword == 'force'
        hash_pattern = re.compile(r'^[\d\w]=.')
        entries = spawn('zsh', '-ic', 'hash -d')

        self.fm.bookmarks.update_if_outdated()

        for i in entries.split('\n'):
            if hash_pattern.match(i):
                key, value = i[0], i[2:]
                if force or not key in self.fm.bookmarks.dct.keys():
                    self.fm.bookmarks[key] = Directory(value)

Then use the command :hash_to_bookmarks to grab the bookmarks from zsh (only one-letter long ones).
:hash_to_bookmarks force allows to overwrite existing bookmarks).

Re: Ranger, a textbased filemanager

Hello, PotatoesMaster. Thank you for your help!
One thing: hashes in zsh can be used as destination points while copy, move and other operations. It would be great to use ranger`s bookmarks in such way, but I`ve not realized the way to do this. E.g.:

:shell for i in ~dir1 ~dir2 ~dir3 ... ~dir'n' ; do cp %f $i; done

Re: Ranger, a textbased filemanager

To use zsh alias, functions and stuff with the shell command, edit ranger/defaults/commands.py and replace the line #163 (in shell.execute())

self.fm.execute_command(command, flags=flags)

with

self.fm.execute_command("zsh -ic '" + command + "'", flags=flags)

Re: Ranger, a textbased filemanager

PotatoesMaster, thank you again! Zsh stuff get worked!
The only annoying detail happens every time I use zsh alias or hash, the command work properly but ranger itself goes to background and stays there untill command fg entered.
Meanwhile ranger is suspended, shell demonstrates: zsh: suspended (tty output)  ranger.
I`ll try to swap some zsh options to get over.
