Use the command as defined by Babel. This allows us to use the (more
advanced) Babel command if provided instead of rolling our own.
I add a dummy file format change in case it turns out we need to
do something here for old documents (e.g. with user preamble definitions)
The idea here is to force commands to be run syncrhonously when
they are launched via "command-sequence" or "repeat". We do this
by using a new flag in FuncRequest.
When computing a cell metrics, it is now possible to specify whether it
is tight (at least as tall as 'x') or not (as tall as the max height of
the font).
Use this to make sure that grid insets have large enough cells. It
will probably appear that other cells needn't be tight. Currently, the
only cell which is known to be tight is the nucleus of the root inset.
Others should be examined one by one. It might be that the default of
MathData::metrics tight parameter should be `false'.
Fixes bug #11050.
This change also applies to Comment insets. For example, Greyedout
and comment insets can now be inserted in section titles.
The usage of these insets in commands relies on the newly
implemented cprotect feature. The usage of these insets in
description items already worked fine (without cprotect).
This commit also enables modification of these insets (e.g.,
converting a LyX note to a Greyedout note) in commands.
This commit is related to #6969.
The problem was that, if we killed export when some graphic was
being converted, or some external template was being handled, it
would only cancel that process, and then it would just continue.
To deal with that, we need to do a few things:
1. Modify the return values for some of the Converters routines,
and similarly the routines for external templates, so we can
tell when something has been canceled.
2. Throw an exception from InsetGraphics or InsetExternal when this
has happened during export, but ONLY when the Buffer is a clone.
We shouldn't be able to 'cancel' export when we're, say, generating
code for the preview pane, but this keeps us on the safe side..
The exception then has to be caught, obviously, back in the export
routines in Buffer.
Probably Coverity will be unhappy about something here, but I'll
deal with that problem as it arises.
This commit follows 8d2b121e and is not expected to change
functionality (e.g., I confirmed that the cases of #7330 and #11106
are still fixed). The advantages of this refactoring are the
following:
- Remove some preprocessor directives:
processingThreadFinished() is only called in the case that
EXPORT_in_THREAD is 1, so by moving some code up in the call list,
the directives are not needed.
- If errors() is called when there is no error, there will not be unexpected
behavior (e.g., as was the case before 8d2b121e).
Note that errors() is still only called by the code touched by this commit
if there is an error, but that is for efficiency and readability.
- The "from_master" argument now has a constant meaning. Before, it
could be the case that "from_master" was set to false but that the
master's error dialog was shown.
