certdoctorThe window
The same diagnosis without a terminal, for anyone who would rather type an address into a box.
What it does
Type the address that fails, press Diagnose, and read the report: the sentence naming the cause on top, the layers on the left, the evidence of each one beside them. Save the report as HTML, Markdown or JSON for a ticket.
The window runs the command line that sits next to it and shows what it reports, so it knows nothing the command line does not, and the two never disagree. The options it offers are the command line’s switches.
Where it runs
| Your system | The archive | What you run |
|---|---|---|
| Windows on x64 | certdoctor-gui_0.1.0_windows_amd64.zip |
certdoctor-gui.exe, signed |
| Linux on x64 | certdoctor-gui_0.1.0_linux_amd64.tar.gz |
./certdoctor-gui |
| macOS on Apple silicon | certdoctor-gui_0.1.0_macos_arm64.tar.gz |
certdoctor-gui.app, signed and notarised |
Each archive carries the command line as well. The download page has them all.
Keep its files together
The window starts the certdoctor that sits next to it, so keep the files of the archive in one folder.
On Windows, the opengl folder holds a software renderer. On a machine whose graphics driver offers no OpenGL 2.1 - a virtual machine without 3D acceleration, or a Remote Desktop session - the window starts again with it, by itself.
On macOS, keep the bundle and the links next to it together. The signature and Apple’s notarisation belong to the bundle, so a program copied out of it on its own is not the program Apple checked.
On Linux, the window needs a desktop session with OpenGL. It loads libGL.so.1 and libwayland-client.so.0, which a desktop installation has.
What it keeps
One setting: the folder you last saved a report to, in preferences.json in your user folder - AppData\Roaming\fyne\dev.donislaw.certdoctor on Windows, ~/.config/fyne/dev.donislaw.certdoctor on Linux and ~/Library/Preferences/fyne/dev.donislaw.certdoctor on macOS. Fyne, the toolkit the window is built with, creates that folder when the window starts, and an empty one of the same name in your user cache folder. Delete both when you remove the window.
