symlink-editor 1.1.0

A TUI to change the target of a symlink.

symlink-editor

A TUI (text based user interface) written in Python with prompt-toolkit to edit symlinks.

Features:

• The color of the frame indicates whether the target exists or not.
• The color of the path indicates which part of the path is broken.
• The cursor is placed at the beginning of the broken part of the path.
• Tab completion and completion menu showing all existing files and directories at the cursor position.

Installation

This program is distributed via PyPI so you can easily install it with pipx:

$ pipx install symlink-editor

Usage in a terminal

$ symlink-editor path/to/symlink

Integration in other terminal applications

If you want to integrate this program into yazi, ranger or other terminal applications I recommend to use the --window flag. With that all feedback such as error messages or updated link will be displayed in a prompt toolkit window instead of printed to stdout so that they won't be overwritten by the other application before you can read them. You can dismiss the window by pressing Enter, Ctrl+C or Q.

Note that the --window flag can only take effect after all command line arguments have been parsed. That means that it does not apply to error messages from incorrect command line arguments and the output of --help and --version.

For yazi you can add the following to ~/.config/yazi/keymap.toml:

[[manager.prepend_keymap]]
on = [ "e", "l" ]
run = 'shell --block "symlink-editor --window \"$0\""'
desc = "edit symlink"

Running the tests

I am using mypy for static type checking and pytest for dynamic testing. tox creates a virtual environment and installs all dependencies for you. You can install tox with pipx (pipx install tox).

$ tox

In order to make tox work without an internet connection install devpi:

$ pipx install devpi-server
$ devpi-init
$ devpi-gen-config
$ su
# cp gen-config/devpi.service /etc/systemd/system/
# systemctl start devpi.service
# systemctl enable devpi.service

and add the following line to your bashrc:
