LFUN_BUFFER_SAVE_AS has an optional argument where an initial format can be preset
This fixes:
* The remainder of bug #3402: Open Export As dialog when attempting to export to read-only directories
* Bug #8886: 'export as' should default to the default document output format
In e02df14 the return type of doExport was changed from bool to ExportStatus.
All calls except this one were adjusted. This one did now fail because the
numercial value of ExportSuccess is 0.
The new HTML clipboard export could cause error message boxes on copying
data to the clipboard (bug #8866). These are now suppressed, like all other
errors which might occur for preparing the clipboard data.
If we call tex2lyx on a temporary file created from the clipboard, the
file is always in utf8 encoding, without any temporary changes, even if it
contains encoding changing LaTeX commands. Therefore, we must tell tex2lyx
to use a fixed utf8 encoding for the whole file, and this is done using the
new latexclipboard format. Previously, tex2lyx thought the encoding was
latin1.
As a side effect, the -e option is now also documented in the man page.
When we export the file to latex, we use the redefinition_ variable to check whether we should output newcommand or renewcommand. This variable was set by the MathMacroTemplate::metrics() function, and this caused problem when the export is running in a different thread as the GUI.
In general, the metrics() functions should not change the Buffer; we have updateBuffer/updateMacros for that purpose.
Not all accessors did update the data previously. Therefore it could happen
that document export from the command line would output \newcommand, and from
GUI it would output \renewcommand for the same macro, simply because in the
GUI case the data was updated as a side effect of the GUI thread reading some
other member.
I also removed the mutable flag for requires_, since this member is always
set on construction and does not need any lazy update.
The bug was introduced with commit [47f7d447/lyxgit], where the unnecessary trailing bracket in CJK environments was suppresed, but not the preceding bracket (which is only output if CJK is a secondary language).
This is the result of the discussion on the list "2.1.0 Blocker". Thanks to
all contributors!
The main idea is to use thread-local storage for all static variables.
This solution does not need any mutex. For more details, see the comment in
unicode.h.
It is no longer needed, and it had a comment that it needed review...
Now anybody who tries to make a copy again is forced to think about it,
instead of trying and using possibly wrong semantics by accident.
