Re: Ranger, a textbased filemanager

@Google
I'll look into this in the weekend.

@litemotiv
1. Just to confirm, you said your problem also appears when you enter :cd with part of the directory and press TAB? That's strange, because this action should have the same effect as the script I gave you ;(
2. Try :set colum_ratios 3,1 and disable the preview with zpzP. Then g/ and :cd /media/ssh/servername<enter>
3. Does it also happen if you only mount 1 ssh server?
4. If you got IRC or something we could debug this faster

@killua
you can interrupt preview generation with ctrl+c.
If you are using a preview script (scope.sh) you could modify that script and exit without touching these files.

@niksfirefly and Dieter@be
You can traverse directories with the ] key. Also, I like this one:
map("F", fm.open_console("shell -p find . | grep -iI "))
Your idea sounds useful too, lets see if I can implement that

@ramboman
Take a look at the config file called "apps.py" and read the second chapter of the help (by typing "2?"), chapter 2.4 in particular.
(You can get a copy of apps.py by running ranger --copy-config=apps)

Re: Ranger, a textbased filemanager

@hut,

Thanks for the ranger! Very attractive!

Two little questions:

1. On copying rather big files (say, few GiB) I feel some lack of information about current operation state (is the operation finished? has it expected speed - at case of remote filesystem?). Have you thoughts/plans related to some kind of minimal ranger feedback for such cases? -something humble like "56%-78MiB/s" as part of status (bottom) line.

2. I have tested a speed of few file managers for cifs-mounted file transfer (post #4): https://bbs.archlinux.org/viewtopic.php?id=115788 Now I have tested ranger also. Last one is in par with cp and qtFM. Why not with worker and mucommander? Is some kind of buffer size very small by default?

Edit 1). ..or add MiB/s field to Task View

Re: Ranger, a textbased filemanager

How could I change find's behavior so that after a directory is found and opened the find command is left opened so I can immediately start finding a subdirectory/file? I'll give an example because I'm probably not being very clear:

Say I want to open .config/ranger/commands.py. If I want to move with find I have to do the following:

:find .confi
:find ra
:find co

But what I'd like to be able to do is this:

:find .confiraco

Another thing I'd like to add but probably not trivial at all to implement is for :find to be able to guess what directory I mean when there's conflict by also searching the files within the directory. For example, if I had .config/ and .config2/, with .config2/ only having a foobar.txt file inside, then I could still do :find .confira and Ranger would know that I want to go to .config/ranger/, or :find .confifoo to open foobar.txt, or even just :find foobar if there are no other files that conflict in the entire tree.

If I'm not being clear then basically what I want is for :find to behave like the Command-T plugin for Vim.

Re: Ranger, a textbased filemanager

Hi !

I think the behaviour of word-deletion in command mode is a little annoying. It is only possible to delete the last word of the line.

Here is a modification to allow in-text deletion and forward word-deletion :

    # ranger/gui/widgets/console.py
    def delete_word(self, backward=True):
        if self.line:
            self.tab_deque = None
            if backward:
                right_part = self.line[self.pos:]
                i = self.pos - 2
                while i >= 0 and re.match(r'[\w\d]', self.line[i], re.U):
                    i -= 1
                self.copy = self.line[i + 1:self.pos]
                self.line = self.line[:i + 1] + right_part
                self.pos = i + 1
            else:
                left_part = self.line[:self.pos]
                i = self.pos + 1
                while i < len(self.line) and re.match(r'[\w\d]', self.line[i], re.U):
                    i += 1
                self.copy = self.line[self.pos:i]
                if i >= len(self.line):
                    self.line = left_part
                    self.pos = len(self.line)
                else:
                    self.line = left_part + self.line[i:]
                    self.pos = len(left_part)
            self.on_line_change()

Keep up the good job and thanks for all !

Re: Ranger, a textbased filemanager

Probably this function fits better as addition to different class.

I had trouble with some crappy rar archives that had characters encoded not in utf8.
With it all working fine

Re: Ranger, a textbased filemanager

been looking through the RANGER thread here for anything that shows me the curent way to set show hidden files always.
And, perhaps there's been a change as I now use the 'zh' command, though some months back I use something else which
was an optional key command I guess. No matter on that of course as if I can set show all dot file to be the default I can use
'zh' when I like for show/hide.

thanks!

(Sorry I couldn't recall how this was done from when I set it a year or so back. Could be an even more elegant way now perhaps.)

Re: Ranger, a textbased filemanager

You can change that in ~/.config/ranger/config

No matter on that of course as if I can set show all dot file to be the default I can use
'zh' when I like for show/hide.

You can set that in ~/.config/ranger/keys.py (By default ranger user Backspace and ^H to show/hide dot files)

Oddly enough, since some of the latest package updates, i haven't been able to reproduce this. This is interesting, since it had been a persistent problem for me for quite a while.. I'll keep an eye on things to see if it returns, and i'll pm you on irc if it happens again.

Thanks for your help.

Re: Ranger, a textbased filemanager

thanks igndenok !

well, there isn't any config in ~/.config/ranger/
and ctrl H no longer works.
zh does.

I'm hoping I'm wrong on both points.

SO, create a config and put what in it?

appreciated.

Invoking `ranger --copy-config=options` and then editing line 40 of "~/.config/ranger/options.py" accordingly should do the trick. Sorry I can't help with your ^h problem. Does Backspace not work either?

Re: Ranger, a textbased filemanager

That was extremely cool to do thank you Miblo and thank you again igndenok.
I've been hoping to save doing the keystrokes needed to unhide for some while now.
Also, I like 'zh' for unhid/hide. kinda standard I thought.

backspace doesn't do anything same as ctrl H and that's more than fine too.
my system's very very cool thanks to ARCH and the forums and I'm very used
to nothing being perfectly managed due to my skill level.

It's my relentless interest however  (quite the usual around here:-)
and xmonad/tmux/ranger and the rest that have me in awesomeness-land.

thanks everyone.

Re: Ranger, a textbased filemanager

@yvonney: If keys.py doesn't present in ~/.config/ranger, you can invoke ranger with '--copy-config=keys' (according ranger man) and then you can change default keybinding unhide/hide.

Re: Ranger, a textbased filemanager

Sometimes htm(l) files preview (elinks is in use) doesn't work, the error example is: 'utf8' codec can't decode byte 0xd0 in position 511: unexpected end of data. OTOH, 'elinks -dump thisFile.htm' does work without problems. How to cure?

Another problem. If an archive is password-protected, ranger just hangs on this archive selection. 'atool', being called directly, just asks a password. Any ideas to resolve?

Re: Ranger, a textbased filemanager

Custom tags.
Default shortcut: <A-t><tag> with tag in alphanumeric chars + some more (:=+-/*:.!?%#@$ ...).
Can be improved.

Here is a screenshot: http://ompldr.org/vOGZsbQ/ranger_custom_tags.png
And here is the patch: http://pastebin.archlinux.fr/pastebin.php?dl=432213

P.S.: save your ".config/ranger/tagged" if you want to test

Re: Ranger, a textbased filemanager

Thanks for the patches and reports. I've applied your patches, except for the custom tags patch until I modify it for backwards compatibility.

1. On copying rather big files (say, few GiB) I feel some lack of information about current operation state (is the operation finished? has it expected speed - at case of remote filesystem?). Have you thoughts/plans related to some kind of minimal ranger feedback for such cases? -something humble like "56%-78MiB/s" as part of status (bottom) line.

Yes, thats planned

2. I have tested a speed of few file managers for cifs-mounted file transfer (post #4): https://bbs.archlinux.org/viewtopic.php?id=115788 Now I have tested ranger also. Last one is in par with cp and qtFM. Why not with worker and mucommander? Is some kind of buffer size very small by default?

Because ranger doesnt copy, ranger calls cp

basically what I want is for :find to behave like the Command-T plugin for Vim.

The inherent problem with it: ranger would need to scan the whole tree which isn't always desirable. It does look useful though... If you're interested in implementing it yourself, take a look at the commands.py, class find, method quick().

Sometimes htm(l) files preview (elinks is in use) doesn't work, the error example is: 'utf8' codec can't decode byte 0xd0 in position 511: unexpected end of data. OTOH, 'elinks -dump thisFile.htm' does work without problems. How to cure?

I applied groundnuty's patch, upgrade and try again

Another problem. If an archive is password-protected, ranger just hangs on this archive selection. 'atool', being called directly, just asks a password. Any ideas to resolve?

Are you talking about file previews? Indeed, if any program asks for input, things will get screwed up.

can the preview pane be on the bottom? I want it to be the full width of the term.

Edit BrowserView.resize() at ranger/gui/widgets/browserview.py to change the positions of the panes

been looking through the RANGER thread here for anything that shows me the curent way to set show hidden files always.

Add the line "show_hidden = True" to ~/.config/ranger/options.py

Yes, saying about selection I mean it results in preview, and last one results in atool call. Great, I'll wait with all possible patience as far as the issue is a showstopper at my common use cases

Switching the copying backend is trivial, you know a fast replacement for cp?

Can you send me (romanz lavabit com) some files to reproduce the bugs? One where you don't see the preview and one where atool asks for password.

I don't know how you process directory tree, but for single file dd (with few MiB bs) is much faster at my case.

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?

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