+ * @Title: GspellEntry
+ * @Short_description: Spell checking support for GtkEntry
+ *
+ * #GspellEntry extends the #GtkEntry class with inline spell checking.
+ * Misspelled words are highlighted with a red %PANGO_UNDERLINE_SINGLE.
+ * Right-clicking a misspelled word pops up a context menu of suggested
+ * replacements. The context menu also contains an “Ignore All” item to add the
+ * misspelled word to the session dictionary. And an “Add” item to add the word
+ * to the personal dictionary.
+ *
+ * For a basic use-case, there is the gspell_entry_basic_setup() convenience
+ * function.
+ *
+ * If you don't use the gspell_entry_basic_setup() function, you need to call
+ * gspell_entry_buffer_set_spell_checker() to associate a #GspellChecker to the
+ * #GtkEntryBuffer.
+ *
+ * Note that #GspellEntry extends the #GtkEntry class but without subclassing
+ * it, because #GtkEntry is already subclassed by #GtkSearchEntry for example.
+ *
+ * %PANGO_UNDERLINE_SINGLE is used for consistency with #GspellTextView.
+ * If you want a %PANGO_UNDERLINE_ERROR instead (a wavy underline), please fix
+ * [this bug](https://bugzilla.gnome.org/show_bug.cgi?id=763741) first.

+ * @Title: GspellLanguageChooser
+ * @See_also: #GspellLanguage, #GspellLanguageChooserButton, #GspellLanguageChooserDialog
+ *
+ * #GspellLanguageChooser is an interface that is implemented by widgets for
+ * choosing a #GspellLanguage.
+ *
+ * There are two properties: #GspellLanguageChooser:language and
+ * #GspellLanguageChooser:language-code. They are kept in sync. The former is
+ * useful, for example, to bind it to the #GspellChecker's language property
+ * with g_object_bind_property(). The latter is useful to bind it to a
+ * #GSettings key with g_settings_bind().
+ *
+ * When setting the language, %NULL or the empty string can be passed to pick
+ * the default language. In that case, the #GspellLanguageChooser:language-code
+ * property will contain the empty string, whereas the
+ * #GspellLanguageChooser:language property will contain the actual
+ * #GspellLanguage as returned by gspell_language_get_default(). If the user
+ * launches the #GspellLanguageChooser and chooses explicitly a language, then
+ * the #GspellLanguageChooser:language-code property will no longer be empty,
+ * even if it is the same language as the default language.
+ *
+ * Note that if an explicit language (non-%NULL or not the empty string) is set
+ * to the #GspellLanguageChooser, then the #GspellLanguageChooser:language-code
+ * property will not be empty, it will contain the language code of the passed
+ * language, even if the language is the same as the default language.
+ *
+ * Thus, a good default value for a #GSettings key is the empty string. That
+ * way, the default language is picked, and can change depending on the locale.
+ * But once the user has chosen a language, that language is kept in the
+ * #GSettings key.

+ * @Title: GspellTextBuffer
+ * @Short_description: Spell checking support for GtkTextBuffer
+ *
+ * #GspellTextBuffer extends the #GtkTextBuffer class but without subclassing
+ * it, because the GtkSourceView library has already a #GtkTextBuffer subclass.
+ *
+ * # Support of the no-spell-check tag defined by GtkSourceView
+ *
+ * The syntax highlighting engine of the [GtkSourceView
+ * library](https://wiki.gnome.org/Projects/GtkSourceView) has a feature called
+ * “context classes”. One of the standard context classes is
+ * “<emphasis>no-spell-check</emphasis>”: it defines the regions in the
+ * #GtkTextBuffer that should not be spell-checked.
+ *
+ * GtkSourceView creates a #GtkTextTag named
+ * `"gtksourceview:context-classes:no-spell-check"`. gspell reads this tag, to
+ * skip the text contained within the tag.
+ *
+ * If you use the GtkSourceView library in your application, keep in mind that
+ * the #GtkTextTag created by GtkSourceView is for read-only purposes; you
+ * cannot apply it yourself to other regions.
+ *
+ * On the other hand if the GtkSourceView library is not used, you can create a
+ * #GtkTextTag with the same name to mark certain regions in the text that
+ * gspell should skip. As it is not a great API, it is
+ * [planned](https://bugzilla.gnome.org/show_bug.cgi?id=771582) to add an
+ * explicit API in #GspellTextBuffer to set a #GtkTextTag that gspell should
+ * skip.
+ *
+ * See the class description of #GtkSourceBuffer for more information about
+ * context classes.

+ * - Word contractions with an apostrophe. For example "doesn't", which is a
+ * contraction of the two words "does not".
+ * - Compounds with words separated by dashes. For example "spell-checking".
+ *
+ * When to include an apostrophe or a dash in a word? The heuristic is that the
+ * apostrophe must be surrounded by a pango-defined word on *each* side of the
+ * apostrophe. In other words, there must be a word end on the left side and a
+ * word start on the right side.
+ *
+ * Note that with that rule, a word can contain several apostrophes or dashes,
+ * like "rock'n'roll". Usually such a word would be considered as misspelled,
+ * but it's important to take every apostrophes, otherwise the word boundaries
+ * would change depending on the GtkTextIter location, which would lead to bugs.
+ *
+ * Possible improvement: support words like "doin'" or "'til". That is, if the
+ * "internal" word ("doin" or "til") is surrounded by only one apostrophe, take
+ * the apostrophe. The implementation would be slightly more complicated, since
+ * a function behavior depends on the other side of the word.
+ *
+ * When doing changes to the algo here, it should be reflected for the GtkEntry
+ * support as well, to have a consistent behavior.

+ * SECTION:text-view
+ * @Title: GspellTextView
+ * @Short_description: Spell checking support for GtkTextView
+ *
+ * #GspellTextView extends the #GtkTextView class with inline spell checking.
+ * Misspelled words are highlighted with a red %PANGO_UNDERLINE_SINGLE.
+ * Right-clicking a misspelled word pops up a context menu of suggested
+ * replacements. The context menu also contains an “Ignore All” item to add the
+ * misspelled word to the session dictionary. And an “Add” item to add the word
+ * to the personal dictionary.
+ *
+ * For a basic use-case, there is the gspell_text_view_basic_setup() convenience
+ * function.
+ *
+ * The spell is checked only on the visible region of the #GtkTextView. Note
+ * that if a same #GtkTextBuffer is used for several views, the misspelled words
+ * are visible in all views, because the highlighting is achieved with a
+ * #GtkTextTag added to the buffer.
+ *
+ * If you don't use the gspell_text_view_basic_setup() function, you need to
+ * call gspell_text_buffer_set_spell_checker() to associate a #GspellChecker to
+ * the #GtkTextBuffer.
+ *
+ * Note that #GspellTextView extends the #GtkTextView class but without
+ * subclassing it, because the GtkSourceView library has already a #GtkTextView
+ * subclass.
+ *
+ * If you want a %PANGO_UNDERLINE_ERROR instead (a wavy underline), please fix
+ * [this bug](https://bugzilla.gnome.org/show_bug.cgi?id=763741) first.

+ * SECTION:region
+ * @Short_description: Region utility
+ * @Title: GspellRegion
+ * @See_also: #GtkTextBuffer
+ *
+ * A #GspellRegion permits to store a group of subregions of a
+ * #GtkTextBuffer. #GspellRegion stores the subregions with pairs of
+ * #GtkTextMark's, so the region is still valid after insertions and deletions
+ * in the #GtkTextBuffer.
+ *
+ * The #GtkTextMark for the start of a subregion has a left gravity, while the
+ * #GtkTextMark for the end of a subregion has a right gravity.
+ *
+ * The typical use-case of #GspellRegion is to scan a #GtkTextBuffer chunk by
+ * chunk, not the whole buffer at once to not block the user interface. The
+ * #GspellRegion represents in that case the remaining region to scan. You
+ * can listen to the #GtkTextBuffer::insert-text and
+ * #GtkTextBuffer::delete-range signals to update the #GspellRegion
+ * accordingly.
+ *
+ * To iterate through the subregions, you need to use a #GspellRegionIter,
+ * for example:
+ * |[
+ * GspellRegion *region;
+ * GspellRegionIter region_iter;
+ *
+ * _gspell_region_get_start_region_iter (region, ®ion_iter);
+ *
+ * while (!_gspell_region_iter_is_end (®ion_iter))
+ * {
+ * GtkTextIter subregion_start;
+ * GtkTextIter subregion_end;
+ *
+ * if (!_gspell_region_iter_get_subregion (®ion_iter,
+ * &subregion_start,
+ * &subregion_end))
+ * {
+ * break;
+ * }
+ *
+ * // Do something useful with the subregion.
+ *
+ * _gspell_region_iter_next (®ion_iter);
+ * }
+ * ]|
+ */
+
+/* With the gravities of the GtkTextMarks, it is possible for subregions to
+ * become interlaced:
+ * Buffer content:
+ * "hello world"
+ * Add two subregions:
+ * "[hello] [world]"
+ * Delete the space:
+ * "[hello][world]"
+ * Undo:
+ * "[hello[ ]world]"
+ *
+ * FIXME: when iterating through the subregions, it should simplify them first.
+ * I don't know if it's done (swilmet).
