how to show current directory in ipython prompt

Question

Is there is way to show the current directory in IPython prompt?

Instead of this:
In [1]:

Something like this:
In<~/user/src/proj1>[1]:

for showing current working directory you can use pwd command — Harish, Jul 20 '16 at 12:39

You can use os.getcwd(current working directory) or in the native os command pwd.

In [8]: import os

In [9]: os.getcwd()
Out[9]: '/home/rockwool'

In [10]: pwd
Out[10]: '/home/rockwool'

I know these commands, but is it possible to show them in the prompt, so I don't have to type every time? – motam79 Jul 20 '16 at 13:21

Using ! before pwd will show the current directory

In[1]: !pwd
/User/home/

When interactive computing it is common to need to access the underlying shell. This is doable through the use of the exclamation mark ! (or bang) To execute a command when present in beginning of line.

pwd is not recognized as an internal or external command – KansaiRobot Jul 31 '20 at 01:41

@KansaiRobot you're probably in MS Windows in cmd.exe shell, in which case `cd` should do the same thing as pwd. So in IPython, do `!cd`. – michael_teter Feb 08 '22 at 08:58

According to:

https://ipython.org/ipython-doc/3/config/details.html#specific-config-details

In the terminal, the format of the input and output prompts can be customised. This does not currently affect other frontends.

So, in .ipython/profile_default/ipython_config.py, put something like:

c.PromptManager.in_template = "In<{cwd} >>>"

Is it possible to only show the last directory? Can I write a custom function on cwd like split? – motam79 Jul 20 '16 at 13:41

Assuming you're interested in configuring this for all subsequent invocations of ipython, run the following (in a traditional shell, like bash :) ). It appends to your default ipython configuration, creating it if necessary. The last line of the configuration file will also automatically make all the executables in your $PATH available to simply run in python, which you probably also want if you're asking about cwd in the prompt. So you can run them without a ! prefix. Tested with IPython 7.18.1.

mkdir -p ~/.ipython/profile_default
cat >> ~/.ipython/profile_default/ipython_config.py <<EOF

from IPython.terminal.prompts import Prompts, Token
import os

class MyPrompt(Prompts):
    def cwd(self):
        cwd = os.getcwd()
        if cwd.startswith(os.environ['HOME']):
            cwd = cwd.replace(os.environ['HOME'], '~')
            cwd_list = cwd.split('/')
            for i,v in enumerate(cwd_list):
                if i not in (1,len(cwd_list)-1): #not last and first after ~
                    cwd_list[i] = cwd_list[i][0] #abbreviate
            cwd = '/'.join(cwd_list)
        return cwd

    def in_prompt_tokens(self, cli=None):
        return [
                (Token.Prompt, 'In ['),
                (Token.PromptNum, str(self.shell.execution_count)),
                (Token.Prompt, '] '),
                (Token, self.cwd()),
                (Token.Prompt, ': ')]

c.TerminalInteractiveShell.prompts_class = MyPrompt
c.InteractiveShellApp.exec_lines = ['%rehashx']
EOF

(c.PromptManager only works in older versions of ipython.)

!dir shows the current directory and the contained files. The directory is shown with single backslashes, that simplifies the handling of the path (at least when using windows).
