Powershell `cd` that reads your mind

This project is not actively maintained. Please consider using its successor ZLocation.

Jump-Location: A cd that learns

If you spend any time in a console you know that cd is by far the most common command that you issue. I'll open up a console to it's default location in C:\Users\tkellogg or C:\Windows\system32 and then issue a cd C:\work\MyProject. Set-JumpLocation is a cmdlet lets you issue a j my to jump directly to C:\work\MyProject.

It learns your behavior by keeping track of how long you spend in certain directories and favoring them over the ones you don't care about. You don't have to use Jump-Location as a replacement for cd. Use cd to go local, and use Set-JumpLocation to jump further away.

Jump-Location is a powershell implementation of autojump.

How it knows where you want to go

It keeps track of how long you stay in a directory and builds a database. When you use the Set-JumpLocation or j command, it looks through the database to find the most likely directory and jumps there. You should only need to give it a 2-3 character hint. For instance, on mine I can do:

• j de -> C:\Users\tkellogg\code\Jump-Location\bin\Debug
• j doc -> C:\Users\tkellogg\Documents

What if you have several projects and you want to get to the Debug directory of one that you don't use very often? If you're jumpstat looks like this:

255    C:\Users\tkellogg\code\Jump-Location\bin\Debug
	50     C:\Users\tkellogg\code\MongoDB.FSharp\bin\Debug

Using j de will jump to Jump-Location\bin\Debug. But use something like j mo d if you really want to go to MongoDB.FSharp\bin\Debug. You can issue a j mo d. mo matches MongoDB.FSharp and d matches Debug.

j internally calls Push-Location, so you can navigate back in your visited locations stack with popd or special Jump-Location query j -.

Quick Primer on jumpstat

You can use jumpstat to see what's in the database. In tradition with autojump, the database is saved to ~\jump-location.txt. You can open up that file and make changes. The file will auto-load into any open powershell sessions.

Since we're in Powershell (and not legacy Bash) jumpstat returns objects. This means that you don't ever have to know anything about ~\jump-location.txt. You can manipulate the objects it returns. For instance, this is valid:

PS> $stats = jumpstat
PS> $stats[10].Weight = -1
PS> jumpstat -Save

Setting a weight to a negative number like that will cause it to be blacklisted from all jump results. Use the jumpstat -All option to see negative weights included in the jumpstat result set.

When you remove/rename directories, Jump-Location database can become out of sync with the file system. Your top-choice will pointed to an invalid location. You can cleanup database with jumpstat -cleanup. It will remove all records with non-existing paths.

Jumpstat can also be used with the "scan" parameter (jumpstat -scan) to recursively scan sub-directories into the database with 0 Weight. This is a quick way to teach Jump-Location about related directories without having to manually cd'ing to each one individually.

Add all subfolders of the current directory:

jumpstat -scan . 

Installation

Important: Jump-Location requires PowerShell version 3 or higher. Older installations of Windows 7 may only have PowerShell version 2. How to update powershell.

Recommended: Install from psget.net:

Install-Module Jump.Location

There is also a Chocolatey package for Jump-Location. To install via Chocolaty

choco install Jump-Location

Otherwise you can still install it manually.

1. Download the latest release.
2. Open properties for zip file and click "Unblock" button if you have one.
3. Unzip
4. Open a PowerShell console
5. Run .\Install.ps1. You may need to allow remote scripts by running Set-ExecutionPolicy -RemoteSigned. You may also have to right-click Install.ps1 and Unblock it from the properties window. Alternative: Add line Import-Module $modules\Jump-Location\Jump.Location.psd1 to your $PROFILE, where $modules\Jump-Location is a path to folder with module.

Next time you open a PowerShell console Jump-Location will start learning your habits. You'll also have access to the j and jumpstat aliases.

If you get errors after installation, try unblocking the file Jump.Location.dll manually by one of the following methods to clear the "untrusted" flag:

1. Copy the file to a FAT32 file system (such as a memory card) and back.
2. Run cmd /c "echo.>Jump.Location.dll:Zone.Identifier"

If you find any bugs, please report them so I can fix them quickly!

Build from source

From root directory:

1. Run msbuild .
2. Run .\copyBuild.ps1

In directory Build you will have local build of module.

TODO

1. Local search. j . blah will only match dirs under cwd. Using . will also search outside the DB.
2. Better PS documentation

jump-location's Issues

Jump-Location doesn't work with PSReadLine

PSReadLine use worker thread to capture user input. That prevents generation of OnIdle events, because engine is never OnIdle.

Jump-Location subscribe UpdateTime callback to OnIdle events.

Maybe this should be addressed in PSReadLine.

Importing Jump-Location in Visual Studio 2015 Package Manager causes weird errors

I was running an Entity Framework helper command to run all code-first migrations on the database when this happened:

PM> update-database
System.ArgumentNullException: Value cannot be null.
Parameter name: type
   at System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes)

I only get this error when I start Visual Studio 2015 and import the Jump.Location module, removing the import from my profile.ps1 and restarting Visual Studio will fix it.

Preferably this error is fixed, but if it's hard then I would be content with at least a warning that you should only import it in the default console version or ISE.

Installation does not work

I am getting the following error when trying to install from psget.net

Write help documentation

When you call 'man j' and 'man jumpstat' your should get help about usage.
Help should include scenarios:

1. simple scenario
2. j -

CommandNotFoundException

I have been using Jump-Location for quite some time now. Today I suddenly started having a problem when opening a powershell window. I'm getting the following error:

Set-JumpLocation : The term 'Set-JumpLocation' is not recognized as the name of a cmdlet, function, script file, or operabl e program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

I've reinstalled Jump-Location but the error persists. Any clue what is going on?

jumpstat should not reclassify directories with negative weight

I'm assuming here that the only way a directory can get a negative weight is by manually editing it, as stated in the wiki. Please tell me if I'm wrong.

Related to #15, the way I'm excluding the poshgit directory is by assigning it a negative weight. I find this absolutely acceptable, more than the plugin trying to guess that I didn't want it to begin with. The problem is that every time I open the shell, the directory gets reevaluated and back in the list. I think if I assigned a negative weight (if that's the only way to get a negative weight) it implies I don't ever want to jump to that folder. It should be kept forever negative, never readded.

j silently fails to change directory if top choice doesn't exists anymore

repro:

1. create directory C:\AAAAA_1
2. spend 2n seconds in it
3. create directory C:\AAAAA_2
4. spend n seconds in it
5. remove C:\AAAAA_1
6. go to some folder.
7. call 'j AAAAA'

expected:
change directory to C:\AAAAA_2

actual:
directory is not changed, no error message

Issue with space in folder names

First off, I love this tool!

But...

I can't navigate to a folder if the name of a folder in the entire path contains a space. It works perfect for paths without space in the folder names.

See image for error message...

Move directory cause invalid path to be top choice

Repro:

1. Create directory 'LongNameDrectory'
   go to it and spend some time
2. Rename directory to 'LongNameDirectory' (fix typing)

Now it impossible to 'j long', since invalid path is top choice.

Problem in current callback implementation

The Job that updates time failed and cannot continue, so statistic is not updates anymore.
Exception calling "UpdateTime" with "1" argument(s): "You can't call CloseAndUpdate multiple times"

Is this repository dead?

The patient appears to be more dead than alive.

For my needs the following function placed in the PowerShell profile script is enough:

function j {
    Param(
        [Parameter(Mandatory=$true, Position=0)][string]$locationName
    )

    $locations = @{
        "one" = "C:\path\to\location-one"
        "two" = "C:\path\to\location-two"
        "three" = "C:\path\to\location-three"
    }

    if ($locations.ContainsKey($locationName))
    {
        Set-Location $locations.$locationName
    }
    else
    {
        Write-Host -ForegroundColor Red "Unknown location: $locationName"
    }
}

jump-location overrides tab behavior of posh-git

If I install jump-location after poshgit, tab key is not working for poshgit.

solvable by changing Powershell_profile.ps1 manually

# Load Jump-Location profile
Import-Module 'C:\Chocolatey\lib\Jump-Location.0.5.1\tools\Jump.Location.psd1'

# Load posh-git example profile
. 'C:\tools\poshgit\dahlbyk-posh-git-95df787\profile.example.ps1'

Jump to number fails using WMF/PowerShell 5 Production Preview

Jump-Location seems to be having problems with PowerShell 5 Production Preview. It is, in some cases, unable to jump given just a number.

PS> mkdir 7\test
PS> cd 7\test
PS> cd ..\..
PS> jumpstat
Weight          Path
------          ----
57,1669311      C:\temp

It does work again if the folder with the number is in the jumpstats

PS> cd 7
PS> cd ..
PS> jumpstat

57,1669311      C:\temp

Doesn't work on PowerShell Core

Just downloaded this module and happily installed it. But when I want to j to somewhere, it complains:

My powershell version is Core 6.0.1, I also tried on my native PowerShell, it works well.

Cannot move through folders that contain a space in the name.

A bunch of windows programs (and folders) that I navigate to include spaces in their names, which instantly results in Jump-Location failing. Usually with a message like:

Non-actionable error message in case if ~\jump-location.txt corrupted

I'm getting this error after installing Jump-Location:

I have tried the two suggestions for errors after install but none of those worked for me.

Not sure if it is related but I had Jump-Location installed via chocolatey (v0.5.1) which I uninstalled and then installed the new version (v0.6.0) via the Install-Module.

Add "jumpstat -scan path" to recursively populate subfolders to DB with 0 weight

Obviously a request and not a bug :) I have a very complex project structure and I'm usually going around in the console just to look at files. It could be awesome if I could "j [somepartofthesubfoldername]" and that will go directly to the first subfolder it finds. "j x" already goes back for me (the main folder starts with x), so that works great.

Register-EngineEvent should use -SupportEvent switch

http://learn-powershell.net/2013/01/30/powershell-and-events-engine-events/

Import-Module Jump-Location slows down powershell 5 times on burning console benchmark

Benchmark: http://www.leeholmes.com/blog/2005/12/18/burn-console-optimized-and-ready-for-marshmallows/

Drops from 54 fps to 10 fps

This most likely totally related to using break-point on $pwd for tracking directory changes. We need to find a better way to achieve same thing.

Use Set-JumpLocation for local folders as well

Is there a chance you could add functionality that would allow a complete replacement of the cd command, e.g. so I could also jump to local folders and j would include local folders in the mix with some priorities? The priorities could be defined by a user-defined option:

• always higher than remembered folders. First autocompletion would be local, subsequent {Tabs} would bring the remembered
• always lower than remembered folders
• -1 to ignore local folders completely for people who for some reason differentiate between cd local folders and j outside folders
  That would make the currently old and dysfunctional cd command into something quite smart and useful.

Jumpstat should not use Console.WriteLine

Call to jumpstat should not output anything to console by default.
Consider replace by -Verbose output

Here is sample, where I call jumpstat from $profile to display statistic:

"Number of records: 132" is pretty confusing message, when you don't call jumpstat from interactive session.

Jump.Location breaks autocompletion with PoshGit

After installing Jump.Location (which is neat btw) autocompletion stops working with PoshGit.
If I dont load Jump.Location, autocompletion works again.

Jump-Location should prefer closer jumps

I feel that closeness of destination is more impotent then time spend in directory.

Scenario:
I have work under
e:\branch1\source\foo
e:\branch1\source\bar [Big weight]
Now I'm under
e:\branch2\source\foo
and I also have
e:\branch2\source\bar in db

After execute
'j foo' I expect go to e:\branch2\source\bar, not to e:\branch1\source\bar

I should add test for this scenario.
Consider, replace time spended in dir by more sophisticated algorithm: like one that have sublime-text-2 Ctrl+P function.

Both psget and choco installations fail to work in different ways (Windows 7, Powershell V3)

Split paths at dashes and underscores too

I have paths like C:\Code\New-Machine. When I think about this as a jump location, I think "nm", however the path segment approach only sees it registered as "ne" at best.

If I was to take a crack at this, is Record.GetPathSegments the likely place to start?

Not able to navigate to similar substring directories

I have 2 folders C:\Mercurial\Foo and C:\Mercurial\Foo.Bar in my jumplist. I am unable to properly jump to the first as everything points to the second. This may be because the second has a higher weight, but I shouldn't have to keep modifying the first ones weight to be higher. How can I jump to C:\Mercurial\Foo?

Jump commands that I have tried to reach first folder:

• j f
• j m f

Please use an approved verb

Please consider using an approved verb so we don't have to suffer the module system's warnings. Jump is fine for an alias, but it's not just about that. The verb/noun system breaks down if we don't stay consistent. Yes, strictly speaking "jump" makes more sense to you, but those of us who are using powershell for many years prefer standard verbs and won't go looking for jump. Plus, it makes me itch in an unscratchable place in my brain when I see non-standard verbs.

Suggestions:

• select-location
• find-location

Thanks,

Make Set-JumpLocation -Push parameter default behavior and remove this parameter. Add 'j -' for 'popd'

Unnecessary message on startup

What's the rationale for printing the [Jump-location] Database contains XX records message to stdout when you load the module? I think if the user wants this information they should query for it.

All history losses

I lose history of locations twice (about once a week). I don't have repro. I even haven't close powershell last time I guess. It's very frustrate.
