 gspell - dev notes
 ==================

+Flatpak support
+---------------
+
+At the time of writing, gspell is not installed as part of the GNOME runtime, so
+it needs to be bundled with the app.
+
+hunspell and hunspell dictionaries are installed by the Flatpak freedesktop.org
+runtime, they are not shared with the host OS. See the
+[freedesktop-sdk](https://gitlab.com/freedesktop-sdk/freedesktop-sdk/)
+repository (`git grep -in hunspell`).
+
+Adding words to the personal dictionary works, but each Flatpak app has a
+different personal dictionary. For example for Polari the personal dictionary
+is stored in:
+
+```
+~/.var/app/org.gnome.Polari/config/enchant/
+```
+
+It works thanks to the `XDG_CONFIG_HOME` environment variable (Enchant calls the
+`g_get_user_config_dir()` GLib function).
+
+To share personal dictionaries between Flatpak apps, maybe a good solution is to
+set the `ENCHANT_CONFIG_DIR` environment variable to a common path (if set, it
+has a higher priority than `XDG_CONFIG_HOME`).
+

 - For the inline GtkTextView spell-checker, GtkSpell checks the whole

-  copy of the GtkSourceRegion utility (from the GtkSourceView project) is used

-  check only the visible regions of the GtkTextBuffer (only the text currently
-  displayed in a GtkTextView).
- Different API. gspell has more classes, while all GtkSpell public functions

 Why a separate library?
 -----------------------
@@ -25,24 +24,20 @@ The non-GUI parts of gspell could be implemented in GIO, with an extension
 point to not hard-depend on Enchant. And the GUI parts could be implemented in
 GTK.

-I (Sébastien Wilmet) created gspell as a separate library for several reasons:
- Be able to iterate on the API more freely, and have something working (and
-  used by several apps) in less time. Now gspell-1 has a stable API, but
-  nothing prevents me from bumping to gspell-2 to break the API, making the new
-  major version parallel-installable. For the time being, GIO is stuck at
-  version 2, which means that breaking the API is not possible there.
- Be the maintainer. If I wanted to integrate spell-checking in GIO and GTK,
-  the project would have taken much more time. With a separate library, it was
-  done in a little more than 6 months, working on and off on it (and
-  part-time). I didn't want to be blocked on my work because of a lack of
-  reviews.
- Having the code self-contained. Having all the spell-checking-related code in
-  one repository. The biggest `*.c` file currently contains 1400 lines. Mixing
-  all the GtkTextView support of gspell into GtkTextView itself would make the
-  code less clear and thus harder to maintain, in my opinion. The first chapter
-  of the book “Large-Scale C++ Volume I: Process and Architecture” (by
-  John Lakos) suggests to me that it was a good idea to create gspell as a
-  separate library, and that it would actually be a bad idea to integrate
-  spell-checking into GTK. A 14k lines of code module (the current gspell's
-  size) is already a good size to reason about the correctness of the code (to
-  focus our attention on features related to spell-checking only).

-different personal dictionary. For example for Polari the personal dictionary
-is stored in:
-~/.var/app/org.gnome.Polari/config/enchant/
-It works thanks to the XDG_CONFIG_HOME environment variable (Enchant calls the
-g_get_user_config_dir() GLib function).
-To share personal dictionaries between Flatpak apps, maybe a good solution is
-to set the ENCHANT_CONFIG_DIR environment variable to a common path (if set, it
-has a higher priority than XDG_CONFIG_HOME).
