autojump - the cd command that learns - new version

lardon · 2011-08-17 07:41:25

Just remove ~/.local/share/autojump/autojump_py*. I don't know what you mean by "safe", though. If you remove these files, autojump will forget everything, but should keep working normally.

I deleted it but autojump completely stopped work for me.

$ cd /tmp
tmp $ cd ~
$ j tmp
$
$ pwd
/home/facade

$ ls -l ~/.local/share/autojump
total 0

Hum, weird. Can you post the output of your $PROMPT_COMMAND? Are you sure you are sourcing everything properly?

graysky · 2011-08-19 10:11:20

SUre...

$ echo $PROMPT_COMMAND
history -a

$ head ~/.bashrc
echo -e "\x1B]2;$(whoami)@$(uname -n)\x07"; # set gnometerminal title

[ -f /etc/profile ] && . /etc/profile
[ -f /etc/bash_completion ] && . /etc/bash_completion

export EDITOR=vim
export VISUAL=vim
set -o vi
PS1='[\u@\h \W]\$ '

The prompt command is your problem: it's supposed to contain autojump-related stuff. Something in your setup overwrites it (is your /etc/bashrc up to date?), so autojump won't work. Either find what the root problem is, or set it again at the end of your bashrc.

graysky · 2011-08-20 10:01:16

@lardon - I don't have /etc/bashrc on my system apparently.

$ pacman -Qo /etc/bashrc
error: failed to read file '/etc/bashrc': No such file or directory

Here is my ~/.bashrc

As you can see, it does source /etc/profile as your script asks...

> You need to source /etc/profile in your ~/.bashrc for this to work
> only guaranteed to work with bash
Optional dependencies for autojump
python2: needed for jumpapplet

EDIT: ok... I put a line in my ~/.bashrc to source /etc/profile.d/autojump.bash but why did I have to do this? It worked fine prior to me deleting the database. Your thoughts are appreciated.

The problem is the following line in your .bashrc, that overwrites the PROMPT_COMMAND:

PROMPT_COMMAND='history -a'

The proper way to add stuff to the prompt command would be the following:

export PROMPT_COMMAND="new_command ; ${PROMPT_COMMAND:-:}"

graysky · 2011-08-21 15:05:40

<headsmack>
Made the change you recommended and removed the line I added to manually source autojump.bash. Now autojump works again. Thank you!

Hey lardon, very useful utility. I've only discovered it recently, and autojump has already saved me a gargantuan amount of typing.

Thanks for your contribution!

@veek: Thanks! I'm glad you like it!

lardon · 2011-11-18 13:38:59

I've just uploaded version #18, which, apart from the usual bug fixes, uses a text format database. This change allows you to edit by hand the autojump database (in ~/.local/share/autojump) if you want to.

graysky · 2011-11-18 14:21:54

@lardon - Very cool, thanks! So the idea is that users can edit ~/.local/share/autojump/autojump.txt and then autojump will translate that into~/.local/share/autojump/autojump_py so the application effectively uses the text file as the db?

For those who can't wait for pkg in [community] to get updated, apply this patch to the current PKGBUILD from ABS and build.

Actually, when you install the new version, autojump will convert autojump_py into autojump.txt (the old file will stay there just in case), and start using that one, which you can safely edit.

Thanks for posting the updated PKGBUILD!

graysky · 2011-11-20 12:54:34

hmmm... autojump doesn't work on a new Arch install...

I am sourcing /etc/profile in my ~/.bashrc but ~/.local/share/autojump is empty.

$ which $SHELL
/bin/bash
$ j
$
$ cd /media/data
$ j
$
$ ls -l ~/.local/share/autojump/
total 0

@graysky: can you post the value of $PROMPT_COMMAND?

graysky · 2011-11-20 13:34:29

Sure... none of the autojump stuff is in there... why

$ echo $PROMPT_COMMAND
history -a ; echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"

Either something is overwriting it, or /etc/profile is not sourcing autojump. Try sourcing /etc/profile.d/autojump.bash directly?

graysky · 2011-11-20 13:48:50

That works... but wtf?

$ . /etc/profile.d/autojump.bash
$ echo $PROMPT_COMMAND
{ [[ "$AUTOJUMP_HOME" == "$HOME" ]] && (autojump -a "$(pwd -P)"&)>/dev/null 2>>${AUTOJUMP_DATA_DIR}/.autojump_errors;} 2>/dev/null ; history -a ; echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"

Here is my ~/.bashrc which I use on all my machines. This is only happening on one machine though so I doubt it's anything in there.

Do you have /etc/profile.d/autojump.sh? You could check that it's there and that it does in fact source autojump.bash, because it's the file that is sourced by /etc/profile.

Just discovered this great little tool a few days ago, loving it already!

Thanks for this,

lardon · 2011-11-29 16:45:54

I've just pushed a patch that allows autojump to be used with cp and mv. I'd be grateful if a couple people could test this and tell me what they think (you need to get the latest git version).

The idea is to add autojump functionality to "cp" and "mv". When you type something like:

cp data.txt dest__<Tab>

The "__" triggers autojump, which will attempt to complete "dest" like j would do it. That should be pretty useful when copying stuff from one place to a totally unrelated place.

Any thoughts? How could this be improved?

jjacky · 2011-11-29 20:57:36

Just tried the new autocomplete quickly, nice. Could it work for other command as well, e.g. ls, vi, less, cat, etc?

Not really related, though it applies as well, but apparently autojump doesn't recognize parents of a visited folder. That is, see this:

[0][jjacky@arch ~]$ mkdir -p /tmp/one/two/three
[0][jjacky@arch ~]$ cd /tmp/one/two/three
[0][jjacky@arch three]$ cd -
/home/jjacky
[0][jjacky@arch ~]$ j two # will not work
[1][jjacky@arch ~]$ j three
/tmp/one/two/three
[0][jjacky@arch three]$

It seems because I never actually went to /tmp/one/two, though I did go to a subfolder, it isn't recognized by autojump. Could it be possible to change that, and have parents of visited path recognized as well?

Also, using the same path as above as example, apparently one cannot use e.g. "j ee/" to go to that folder (/tmp/one/two/three). Would be nice if it was possible, because it's useful in cases where the "j ee" jumps to something like "/foo/treepath" -- that is a (probably more visited) path that does have "ee" in its name, but not at the end of it.

It would, but it would quickly become messy, because I would have to add a complete command for each of these commands. Fortunately, I don't think this is needed for unary commands (who take only one argument), since you can simply use j to go to the right folder and open the file from there. This is why I've restricted it to cp and mv for now.

I see that as a feature, although of course it's very hard to cover all the possible use cases. If I added every parent automatically, j would often send you to places where you never go.

That means /foo/treepath is used more and more recently than /tmp/one/two/three. So autojump thinks it's more likely you want to go there. In that case, you can use auto-completion, or a longer pattern.
