Dhop - it takes you places!

[ Usage | Examples | Special Conveniences | Installing | License | Issues ]

Dhop (command name: dhop) is a command-line utility written in Python that provides a number of ways to get around your filesystem quickly:

• set named directory locations and then go to them by name.
• push and pop locations from a stack.
• marking and recalling a single, unnamed location.

Each of these states is persistent and can be used even after your terminal session has finished, your computer rebooted, etc.

You can also copy and move files to any location you've named with set.

Usage

dhop <cmd_or_location_or_path> [command_args]

Where cmd_or_location represents either a named location (recorded with set) or one of the known commands. Any further arguments on the command-line are considered parameters for the given command.

Commands

cp <from>, <to>

Copies the file(s) specified by from to the location specified by to. File-globs can be used in the first argument. If to represents a directory, then the file is copied to the directory, retaining its name. Otherwise, the file is renamed to the name specified in to.

mv <from>, <to>

Moves the file(s) specified by from to the location specified by to. File-globs can be used in the first argument. If to represents a directory, then the file is moved to the directory, retaining its name. Otherwise, the file is renamed to the name specified in to.

set <name> [path]

Sets a name for a specified directory path. If no path is provided, then the name is set for the current directory.

forget <name>

Forgets (deletes) a named location that was previously set.

mark [path]

Marks the provided path so you can later recall it to return. If the location isn't provided, the current directory is assumed. This also overwrites any previous marks.

recall

Goes to the directory that was last marked.

push <path>

Pushes the current working directory to the directory stack, then goes to the location referenced by path.

pop [option]

Pops the last pushed location from the stack, and then transports you to that location. You can set the following option:

• all - Pops all of the pushed locations from the stack, then transports you to the final location popped from the stack.

help

Prints help.

Examples

Example 1: Setting and returning to a named location

dhop set docs ~/Documents

Then you can either use:

dhop docs

or:

dhop go docs

to go to ~/Documents.

Example 2: Marking and recalling a location

dhop mark

marks the current directory (overwriting any previous mark)

dhop recall

takes you back to the marked location.

Example 3: Pushing and popping locations

dhop push

pushes the current directory on the stack.

dhop pop

pops the last pushed directory from the stack and transports you there.

Special Conveniences

I've added these special conveniences because I use them. ;)

Auto-interpretation of paths

If the command isn't recognized, but refers to an actual filesystem location, dhop will assume that you want to go there, so typing:

dhop ~

which will take you to your home directory--well, on *nix, *BSD, and Mac OS X, at least.

Note

If you use dhop on Windows, you may want to go to where your "home" is and type:

dhop set ~

then, just as you would on Linux, you can use dhop ~ to get home. Neat, eh?

Copying and moving files

Using dhop cp or dhop mv will allow you to move files from the current directory to a named location or path. You can copy or move either a single file or a group of files specified with a file-glob. For example:

dhop mv *.md @notes

moves all of the files ending with .md to the location marked by the name "notes".

Installing

1. You must have Python on your system. I've tested this with Python 2.7.5.

2. Get the sources. You can either use git:

   git clone https://github.com/Abstrys/dhop.git
   

   or download the .zip: https://github.com/Abstrys/dhop/archive/master.zip

3. Run either install.sh or install.bat depending on your platform. Here's an example run using install.sh on Mac OS X:

   ./install.sh
   Installing dhop.py...
   
   Install directory already exists: /Users/eronh/bin
   
   Copying files:
   dhop.py -> /Users/eronh/bin/dhop.py
   dhop.sh -> /Users/eronh/bin/dhop.sh
   

   Be sure to add the following line to your .profile, .bashrc, or .bash_profile:

   alias dhop="source /Users/eronh/bin/dhop.sh"
   

   Feel free to cut-and-paste the above line, since it refers to the actual install location. Then, you can simply type dhop on the command-line for help.

4. If you used install.sh (Linux, Mac, BSD, etc.), you'll also need to add a line to your profile (either ~/.bashrc, ~/.bash_profile, or ~/.profile depending on your system), such as:

   alias dhop="source /Users/eronh/bin/dhop.sh"
   

   Invoking dhop with source is necessary to allow dhop to change your working directory in your shell session.

5. Once installed, test it out by typing dhop help.
