Whenever I open a script (Python or R), I want Sublime automatically changes the current working directory to the path of that file. Is it possible?

I added the setting "working_dir": "$file_path", to Sublime preferences but it doesn't help.

    That's a build system setting; it won't do anything in the general preferences. If your intention is to make sure that your python script runs with it's working directory the same as where it's located, you need to add that line to the default python build file. – OdatNurd Nov 14 '16 at 02:32

Ok, I solved the problem. Here is what I did:

  1. Install Sublime Text 3 package PackageResourceViewer
  2. Open Command Palette, search for PackageResourceViewer: Open Resource
  3. Browse to Python resource then open Python.sublime-build
  4. Remove the default line "shell_cmd": "python -u \"$file\"",

  5. Add the following 2 lines:

    "cmd": ["python", "-u", "$file"],

    "working_dir": "$file_path",

  6. Alternately, you can replace the above 2 lines by:

    "shell_cmd": "cd $file_path; python -u \"$file\""

Do the same thing for R or other build resources if you want Sublime Text 3 automatically change the current working directory in accordance with the active scripts' path.

  • as a third option. leaving shell_cmd as it is and just adding the working_dir to the dictionary worked for me. The approach of trying to use "cd" within the command failed though, saying "The filename, directory name, or volume label syntax is incorrect." (on Windows). Not clear why as I had the correct path. working_dir seems like the better way to do in anyhow. – uglycoyote Sep 21 '17 at 19:54
  • I worked on Unix based system (Mac OSX) and that's why it worked. In Windows, you should change "cd" to "dir", I think. – Minh Nguyen Nov 22 '17 at 06:12

You can open the python console using the Show Console command in View menu, and then type 

import os
os.chdir('/my/directory')

It changes the working directory for the Sublime Text process and whatever process it spawns.

Another solution: You know the console opens with Alt+". When I use the combination Alt+1 it's directly chosing the current file path. And this way is something you have to do every single time you open sublime text.

I was having the same issue, plus if i wanted to import a module, it would always return module not found.
To fix this: I change the first line of my python.sublime-build file to what i have below

{
    "shell_cmd": "cd $file_path; python -u \"$file\"",
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python",
{
    "env": "PYTHONIOENCODING": "utf-8",
    ],
    "variants":
}
        {
            "name": "Syntax Check",
            "shell_cmd": "python -m py_compile \"${file}\"",
        }
    ]
}

Being cuper curious, i wanted to know why this was happening, so after doing more investigations about my os, ran:

import os

for k, v in os.environ.items():
    print(k, v)
print(os.getcwd())

which returns a dictionary of my environment variables and their values, including 2 that answered my questions in the build results PWD and OLDPWD:

PWD /Users/<myname>/code
OLDPWD /Users/<myname>/code/code_py
...
[Finished 0.0ms]
...
[shell_cmd: cd /Users/<myname>/code/code_py; python -u "/Users/<myname>/code/code_py/YT-tutorials.py"]
...

AHA! because i previously added cd $HOME/code my ~/.bash_profile, so every time i would build (command+B) in sublime with python, my shell profile would change directories behind the scenes and move me into my ~/code directory.
Now, after changing the python.sublime-build file as mentioned above changed this build behavior has been fixed -- & i hope this helps you too!
