Implement "goldendict://nice" url scheme handler for windows and linux

[shenlebantongying]

To test this, try goldendict://nice on explore.exe's address bar, browser or any editor that supports hyperlinks.

This is an unobvious feature, probably we should document it somewhere, like the wiki or put it in "changes.md" which seems not updated anymore.

If the goldendict already running, GD will use the popup to show the result.

To test Linux version:

• install everything to /usr/ or /usr/local
• run sudo update-desktop-database (depends on how a distro works)
• try xdg-open goldendict://nice

Limitations on linux:

In certain applications like vscode and kde's dolphin, they seems to limit what kinds of link they recognize.

Links in Libreoffice & sublime text & emacs & terminals that supports links, users can just click the link.

.appimage user probably must do what obsidian do https://help.obsidian.md/Advanced+topics/Using+obsidian+URI#Installing+Obsidian+URI

Is it possible to make this feature available on macOS?
I have read this document, but I still don't know how to do it.

Would love to have this feature available on macOS, but I don't know how, and I have little to no idea about macOS development.

Help needed.

I asked about this feature yesterday because I could not get it working and the comment was deleted after I discovered that I had foolishly used the old generation GoldenDict to test it. Sorry about that. But now I have encountered a real problem.

Let me re-introduce some background information first. Diogenes is a popular tool to browse classical texts, and users have been crying for GoldenDict integration for years. I am trying to add that feature by creating a link like <a href="goldendict://$word">GoldenDict</a>. But both Firefox and Chrome URI-encode the href, turning goldendict://οὐετερανός into goldendict://%CE%BF%E1%BD%90%CE%B5%CF%84%CE%B5%CF%81%CE%B1%CE%BD%CF%8C%CF%82. GoldenDict seems unable to handle such URLs and the search term is decoded as CE�ὐετερανός (notice that only the first letter is not properly decoded). Am I doing it in the wrong way? Or is it a real issue and I should open one instead? By the way, xdg-open goldendict://οὐετερανός works very well.

Anyway, thanks for this extremely useful feature!
