Re: Ranger, a textbased filemanager

I appreciate your effort but I want to clarify that this was just a joke-screenshot.
And I don't know any way to display feh inside terminals. (This was mplayer actually)

Does anybody want to implement this?

Re: Ranger, a textbased filemanager

Why don't you write a script that converts large volumes of mail into a tree structure on the file system and use ranger to browse it?

Based on this idea, i've written a small python script, that creates a tree structure of your rss-feeds and uses ranger to browse them. It creates a directory for every news-feed and every entry in this feed is a html file. This file has a summary of the news as a comment (for readability in the preview) and when opened in a browser, it redirects the browser to the page of the news. There's still a lot to do but it is usable.
Since it can't remember, which news you have read you can give it the option to only show news that are younger than X hours. I can provide a PKGBUILD for it, if there's interest.

Re: Ranger, a textbased filemanager

Hi again

i have two short related question that i guess im to stupid to figure out

first im trying to open some images in gimp as a new copy..the command that works in the CLI is gimp -a FILENAME. im issuing this:

:shell -d gimp -a %s

on selected file(s) but it always opens them as the original not a copy (disregarding the -a option)

what am i doing wrong?

also how does one preform a shell command on a bunch of file for example i usually issue this command in a folder of png's:

for i in *.svg; do inkscape -f "$i" -e "${i%%.svg*}.png" -w 128; done

whats the best way to create a ranger alias that issues that command on a bunch of files?

thx alot in advance

best

Zeltak

PS..although i am not a programmer i am more then wiling to help in other areas if needed since i really love ranger

Nice. The world definitely needs a universal "XYZ to files" converter so everything can be browsed with ranger (or your other favourite file browser).
Btw. You could use tags to differentiate between new and old news.

:shell -d gimp -a %s

what am i doing wrong?

I dunno. Actually this works for me.

for i in *.svg; do inkscape -f "$i" -e "${i%%.svg*}.png" -w 128; done

whats the best way to create a ranger alias that issues that command on a bunch of files?

Does this for-command work with ranger? If yes, just map it to a key:

map('x', fm.execute_console('shell -d for i in *.svg; do inkscape -f "$i" -e "${i%%.svg*}.png" -w 128; done'))

If not, there are lots of alternatives: convert the for statement to a find/grep/xargs chain, create a shell script and run it instead, write a command in python,...

PS..although i am not a programmer i am more then wiling to help in other areas if needed since i really love ranger

Well, you could just share the ranger-related stuff that you come up with (ideas, hacks, tools, ...), perhaps in the mailing list to not flood the arch linux forum

EDIT:
To the guys who want colored previews:
Checkout the branch "cp+preview" instead, it supports loading previews in the background. "preview" is obsolete.
+ I experienced cases where ranger keeps loading previews forever. You can press ^C or wdd abort it. fixed

Re: Ranger, a textbased filemanager

The code for custom previews is in the ranger-git AUR package now.

A few screenshots:

It requires two steps to get it to work:

1. Copy the preview script from ranger/data/scope.sh to ~/.config/ranger/scope.sh.
This is done automatically if you type

ranger --copy-config=scope

Go ahead and edit it to your likings.
If you got an older version, please use the new one since some bugs were fixed.

2. install the programs that generate the preview. They're all optional, get only the ones you want.

• archives: atool

• code: highlight

• html: elinks or lynx

• images: img2txt from caca-utils

• pdf: pdftotext

• audio: haven't found a decent music to text converter yet...

Of course you can edit scope.sh and add any other program.

Re: Ranger, a textbased filemanager

Nice! But it doesn't seem to work here... Without the scope.sh in ~/.config/ranger ranger crashes with the following error message, when I'm on a text file

Ranger crashed.  Please report this (including the traceback) at:

With the script in ~/.config/ranger there are no previews, ranger also doesn't show anything when I press F3. All I get is a "[Errno 13] Permission denied" when I'm on a file (filetype doesn't matter) The permissions of the config files are right

Re: Ranger, a textbased filemanager

Ah. The first thing is a python3 issue, the second is that scope.sh needs execute permissions.
I fixed both, thank you for reporting
scope.sh is now automatically chmod u+x'ed when using --copy-config=scope. You'd still have to manually chmod it.

Re: Ranger, a textbased filemanager

Alright, works! Thanks! And this scope script is really nice, now it's very easy to implement "previews" for multimedia files using mediainfo. I'd suggest you put this into the script for audio and video files by default, because like you already said, there's no way to really preview sound or videos with texts.

Re: Ranger, a textbased filemanager

I should talk to a person capable of  synesthesia about whether it's feasable to arrange numbers and letters in a way that you can actually perceive the sound when looking at the preview.
For all the normal people I can add mediainfo too.

Re: Ranger, a textbased filemanager

I remember, some time ago I saw Ranger & thought to myself something in the line of "Who on Earth would want to use something strange like this? I'm not such a geek to even try". Wow, hut, I was so wrong. My curiosity & search for customizable file manager ( like Total Commander in Win' ) drove me to install it. Thank you, Ranger is unusual for me, for sure, but mind-blowing

Re: Ranger, a textbased filemanager

This is really cool, I changed the line for images to

jhead "$path" | head -n $maxln && img2txt --gamma=0.6 --width="$width" "$path" && exit 4 || exit 1;;

Nice!
I'd like to try tiv (in xyne's repo) instead of img2txt, but somehow that doesn't work. Does anybody know how to do it? I tried

tiv -w "$width" "$path" && exit 4 || exit 1;;

and don't know why that doesn't work.

Re: Ranger, a textbased filemanager

It seems like tiv is using ansi escape codes that ranger doesn't handle.

It works if you use scope.sh standalone, right?

~/.config/ranger/scope.sh some_image.jpg $COLUMNS $ROWS

Re: Ranger, a textbased filemanager

hut, I' ve found the following exception, that is printed as is w/o any additional trace info:

close failed in file object destructor:
Error in sys.excepthook:

Original exception was:

Steps to reproduce: Ctrl+S to suspend the urxvt/xterm output while in Ranger, than try to kill it (I've yet found a way to describe it better, but I use "kill client" command in Awesome WM [Mod+Ctrl+C in default config], when "kill -9" does nothing & "kill -15" really kills it immediately). Than I got the message "Type Q or :quit<Enter> to exit Ranger", typed "Q" and got the exception.
Ranger version: 1.3.1 testing (latest from git, like 3 hours before)

Re: Ranger, a textbased filemanager

What python version?
Do you get more information if you start ranger with the --debug option?

Btw. I can't reproduce it. If i suspend (^S) and kill it, it's dead without giving any error message. I use urxvt and awesome too.

Yes it does. But it seams like there's no way to use it in ranger, right? Or do you know some kind of workaround?

Re: Ranger, a textbased filemanager

I dunno, wanna try to patch it? I can't find any documentation on those ansi codes anyway. (pipe the output of tiv into a file to see them)

Re: Ranger, a textbased filemanager

I'm far from being capable for this. But I was rethinking this, in fact img2txt is MUCH faster than tiv, so for this purpose I think it actually suits better.

Re: Ranger, a textbased filemanager

What python version?

2.6.5
Once again I've updated the ranger-git from aur an hour ago, renamed .config/ranger directory to run with defaults, used both "source /usr/bin/ranger /usr/bin/ranger" and "/usr/bin/ranger"

vasya@vahost ~ % which ranger
ranger: aliased to source /usr/bin/ranger /usr/bin/ranger
vasya@vahost ~/.config % ranger
close failed in file object destructor:
Error in sys.excepthook:

Original exception was:
vasya@vahost ~/.config % /usr/bin/ranger
close failed in file object destructor:
Error in sys.excepthook:

Original exception was:
vasya@vahost ~/.config % /usr/bin/ranger -d
close failed in file object destructor:
Error in sys.excepthook:

Original exception was:
vasya@vahost ~/.config %

The only difference in debug mode is that I don't get the message "Type Q or :quit..." & ranger just quits immediately with the same exception. 100% reproducible on my machine (Arch 64b with latest updates to all the software, no testing packages) when I try to kill it with Mod+Ctrl+C in Awesome 3.4.8 with almost default config. Note that it does not happen, if I resume scrolling with Ctrl+Q

Re: Ranger, a textbased filemanager

Two questions,

(1) I want to use Alt + left and right arrow keys to move between tabs. How do I do this? (I assume the changes are added to a copy of keys.py.)

(2) Is it safe to run multiple instances of ranger at once? (No corrupted history, bookmarks, tagged?)

Thank you.

Re: Ranger, a textbased filemanager

@hut -- two small typos in scope.sh:
1. change 'fpdftotext' to 'pdftotext' on line 44
2. change --ansi to --out-format=ansi on line 56

Cool extension! Though the img2txt is so low-res on my laptop as to be unrecognizable. I'd like to see it on a big monitor, though!

Re: Ranger, a textbased filemanager

Once again I've updated the ranger-git from aur an hour ago, renamed .config/ranger directory to run with defaults, used both "source /usr/bin/ranger /usr/bin/ranger" and "/usr/bin/ranger"

Let's continue the discussion of this matter here: https://savannah.nongnu.org/bugs/?31328

I'm far from being capable for this. But I was rethinking this, in fact img2txt is MUCH faster than tiv, so for this purpose I think it actually suits better.

At some point I'll need to add those 256-color codes anyway so stay tuned

(1) I want to use Alt + left and right arrow keys to move between tabs. How do I do this? (I assume the changes are added to a copy of keys.py.)

In fact, I didn't think of that. At the moment, only alt+letters/numbers are recognized. I'm going to patch this soon.
If you don't know how to edit keybindings at all, try ranger --copy-config=keys and take a look at the ~/.config/ranger/keys.py file.

EDIT: It's patched. And alt+arrow keys now change tabs too.

(2) Is it safe to run multiple instances of ranger at once? (No corrupted history, bookmarks, tagged?)

No problems. There's a differend degree of synchronization though. Bookmarks are synchronized immediately between all ranger instances. tags are updated once you do a tag operation (press t) and the history is synchronized on a restart.

1. change 'fpdftotext' to 'pdftotext' on line 44

done

2. change --ansi to --out-format=ansi on line 56

It's both the same for me ?

Cool extension! Though the img2txt is so low-res on my laptop as to be unrecognizable. I'd like to see it on a big monitor, though!

Since this extension makes ranger consume more resources, I tend to turn it off most of the time though. But it's cool in times I really need a preview. E.g. pressing i on archives and scrolling through its contents removes the need to pressing Enter on them.

Awesomeness, thanks for the excellent file manager. 

Only issue I have is that it sometimes freezes while loading previews for large files, especially pdfs.

I think that was fixed a while ago, try upgrading.
If this doesn't help, you can turn the "neutral hut" into a "happy hut" by allowing me to see the traceback. (ranger --debug)

In IRC you asked me if you can use UTF chars for input and I couldn't answer.
Apparently that works only with python2.6, and you gotta add this line at the top of your keys.py if it's not already there:

# -*- coding: utf-8 -*-

If you wanna install ranger with python2.6, edit the PKGBUILD, it gives you some hints.
