any interest in an *-env.txt file for setting env vars for Sigil

[KevinH]

And since there are a number of environment variables used in PageEdit as well, I will be borrowing this new approach from Sigil and bring it to PageEdit.

Unfortunately PageEdit has no plugin capability so no gui here. But for MacOS users editing a line in a text file is so much easier than having to change a gui's launchctl, then rebooting.


Here are the PageEdit environment variables that I have found so far:

PAGEEDIT_DISABLE_NFC_NORMALIZATION
PAGEEDIT_USE_COLORSCHEME_CHANGED
PAGEEDIT_DEBUG_LOGFILE
QTWEBENGINE_CHROMIUM_FLAGS
PAGEEDIT_DISABLE_CURSOR_BLINK
PAGEEDIT_ENABLE_WORD_PASTE_CLEANUP
PAGEEDIT_PREFS_DIR
QTWEBENGINE_DICTIONARIES_PATH
PAGEEDIT_USES_DARK_MODE

I still see SIGIL_USE_COLORSCHEME_CHANGED without a description. Shall we add it?

Yes we need to add it. FWIW, it is really a Linux Only env var.

#if QT_VERSION >= QT_VERSION_CHECK(6,5,0)
#if defined(Q_OS_WIN32) || defined(Q_OS_MAC)
    m_UseAppPaletteEvent=false;
#else 
    if (qEnvironmentVariableIsSet("SIGIL_USE_COLORSCHEME_CHANGED")) m_UseAppPaletteEvent=false;
#endif
#endif

Neither Mac nor Windows use this as it is default for them to use the Qt ColorScheme Changed signal to know when the user has charged from a dark to light scheme or visa-versa.

But this signal really only works on very up to date Linux distributions like an Arch or Manjaro based KDE Plasma 6.3 and later and for some other desktops.

Our old way of looking for a palette change event in MainApplication still works and all Linux boxes default to that method unless the user overrides it with this environment variable.

I use it since I know my Manjaro Linux box with the latest KDE desktop actually works with it but most Linux boxes will probably not.

I will add it to the sigil-user-guide.

Here is the snippet I just added to the User Guide.

<li><p><span class="listheading">SIGIL_USE_COLORSCHEME_CHANGED</span> 
This environment Variable is <b>Linux Only</b>. Setting this tells Sigil that your 
Linux desktop works with Qt's built-in QStyleHints::colorSchemeChanged signal 
for detecting when your desktop theme changes from light to dark and visa-versa.
</p></li>

OK, I've got everything ready. Today I'll publish the official version of the plugin in a new thread.

Thank you!
