[Plugin] EnvVarEditor - GUI editor for Sigil's environment variables

@DiapDealer: Yes, the current version of AppImage would be great.

EDIT:
Unknown lines are saved here:

                    # unknown
                    lines.append(stripped)

@KevinH: Indeed, I had to merge the saved information (some from the dialog box and the rest, the unknown ones, from the file). Thank you.

Happy to get you one. Though I don't think this is a Linux issue at this point:

There's a Sigil-2.6.2-x86_64.AppImage asset at that link.

0.1.2 is now preserving my custom/unknown variables. Thanks! But now I notice that unchecking some boxes in the gui (like for SIGIL_SKIP_UPDATE_CHECK) does not remove (or change) that variable in the file. It stays SIGIL_SKIP_UPDATE_CHECK=1.

I ran a few tests and I hope that both objectives were achieved: restoring the broken deletion of entries without selection or entered values, and preserving unknown environment variables.

A quick test of 0.1.3 looks great! Thanks!

I have published a new version of the plugin in the first post. Feel free to test it.

Here's a planned improvement I hope to add soon: the env-vars.txt file is optional, meaning users can still set environment variables in the traditional way – directly within the system via the command line, another application, or a batch/sh script. My goal is to add a new feature that will display information within a dialog box, letting the user know if a specific Sigil environment variable has been set at the system level instead of in the env-vars.txt file.

TL;DR: The beta version is available in the second post. Minimum Sigil version: 2.7.6

I’ve just uploaded a new beta version of the Environment Variables Manager plugin. This update is specifically designed to support the latest changes in Sigil 2.7.6 while also introducing several "Quality of Life" improvements to the user interface.

What's New in v0.1.15 (Beta):
Support for Unsetting Variables (Sigil 2.7.6+): Following the recent Sigil update, you can now explicitly "unset" environment variables. The plugin now supports the new tilde (~) prefix. In the dropdown menu, simply select "Unset", and the variable will be removed from the environment upon the next Sigil launch.

Smarter UI Automation:

• Auto-Check: When you switch a boolean variable to "Set", the checkbox is now automatically checked for you.
• Auto-Focus & Select: When switching a String or Numeric variable to "Set", the plugin now automatically focuses on that input field and selects the existing text. You can start typing immediately – no extra clicks required!
• Cleaner Logic: Improved handling of system-level variables (like SIGIL_PREFS_DIR) to prevent redundant saves when no actual changes were made.
• Refined Tooltips: Building on the great work by @mrprobert, tooltips and labels have been further polished for clarity.

Note for Beta Testers: This version has been tested on my setup, but since it involves new UI logic (signal blocking to prevent feedback loops), I’d appreciate any feedback – especially if you notice any quirks when switching between "Set", "Not set", and "Unset" modes.

The plugin should be stable, but as always with beta software, keep a backup of your env-vars.txt if you have a very complex setup.

Looking forward to your feedback!
