This commit fixes an issue where the menu option "Insert Separated
Frame Below" would show up twice, with one instance disabled. This
occurred when there was a "Standard" environment nested in a
"Frame". With this commit, the duplicate instance is removed.
The objective is to identify common operations and place them
in functions in order to improve the readability and correctness of the code.
is_document_option(document, option):
Find if _option_ is a document option (\\options in the header).
insert_document_option(document, option):
Insert _option_ as a document option.
remove_document_option(document, option):
Remove _option_ as a document option.
A feature can now be required only for specific input or font encodings:
- <feature>=enc1;enc2... Require the feature <feature> only if the
character is used in one if the specified font
or input encodings.
- <feature>!=enc1;enc2... Require the feature <feature> only if the
character is used in a font or input encoding
that is not among the specified.
The fixes are simple and on line with the changes made during
the 2.3 development. It was an oversight to leave them out.
With this commit all the python scripts should be supported by
python 2 and 3.
Instead of "Save" (permanently) and "Apply" (temporarily), OK and Apply
now always save permanently, unless the new checkbox "Apply to current
session only" is checked.
Addresses: #10016
Compute a height from current font and current cell vertical
dimensions in MathData::metrics(), because this is where current font
is known.
Introduce BufferView::setCaretAscentDescent to remember this value.
This mechanism is not used for text because Cursor::current_font is
restored by undo, and the caret height would not be changed then. But
in principle it is doable.
The new code is much simpler: what it does is, after redrawing has
been done, to mark the cursor row as changed, so that it will be
repainted on next paint event.
This avoids some crashes at the price of possibly repainting the row
when it was not necessary.
The problem is that popping dialogs during reload can cause paint
events for which we are not ready. If this does not work, then we
can introduce a new flag, besides 'busy', for that case. But busy
does not seem to be used very widely, so hopefully this works.
This has the effect that inserting nomenclature entries does not
cut the selection (implicit or explicit) but rather copies it, which
seems to me to make a lot more sense. If anyone objects, let me know.
When the cursor is inside a subscript that may become empty, metrics
issues can happen. This patch fixes the issue, although it is not
clear to see what the problem is.
Still, requesting a metrics update also in the case where the macro
mode is canceled makes sense.
Fixes bug #11125.
Following a request by Günter, we consider the document fonts (only rm
for now) when selecting an appropriate font encoding.
See #9741
The new default font encoding setting "auto" does
* consider the font encoding needed by the language(s), which can now
have fallback alternatives
* Consider which font encoding is provided by the document font
Thus, cm now will result in OT1 fontenc, if the language can deal with
that.
The font_enc pref is ditched: it is no longer needed.
The automatism is still very basic and is subject to extension.
File format and prefs format change.
