If a new paragraph is created just before a nested environment,
the indentation of the nested environment is not computed
correctly because the parindent of the previous layout would
also be erroneously taken into account. This would cause the
nested environment to move back and forth when something is
added to the new paragraph.
Instead of simply taking into account the layout of the previous
paragraph, it is better considering the layout of the environment
in which the previous paragraph may be nested. This makes the test
simpler and, at the same time, more robust.
LyX fails to indent on screen a standard paragraph when it is
nested into an environment. The fix is a one-liner but the diff
is larger because it also fixes a previous wrong indentantion
in the source ;)
This is necessary, for example, if a standard paragraph is nested
in an environment and the environment does not end immediately after.
To be strictly correct, the layout of the following paragraph should
be compared to the layout of the nesting environment, otherwise, if
they are not the same, an empty line is nevertheless output. However,
this is harmless because an "\end{layout}" tag immediately follows.
I am not sure I fully understand the pending_newline/unskip_newline
logic (which seems mainly related to rtl writing), so I prefer to
leave it alone, in the sense that now things go again as in 2.1
until the point where those booleans are used for producing output.
If it turns out that a spurious (and unwanted) empty line comes
from the previous code, it can be easily corrected later.
I am also reintroducing the check about a separator inset at the end
of the paragraph, because that is necessary for the plain version.
This also changes the type of an int to an ssize_t.
nRead is initialized as an ssize_t because it could
be negative. It is cast to a size_t for comparison
to the size of a vector, but only after we check
that nRead is not negative.
This method is a proxy for LyXRC::preview that forces to forward
declare some wrapper around an enum...
Instead, two simple static methods previewMath() and previewText() are
introduced, that make the code much easier to follow.
The format entries should be sorted according to the culture selected for the
UI. This was not the case previously, resulting in unexpected sorting of small
and capital letters. This is now fixed by using the standard C function
strcoll(). Qt does only offer similar functionality in Qt5, and this is not
mature enough yet to depend on it.
Unfortunately we have a report that strcoll() does not work on MSVC, however
this partial fix is better than nothing. The MSVC issue might also be a
configuration problem, since MS claims that strcoll() is supported. This
still needs to be checked.
addPath() always adds a slash at the end, os got a double one before.
Qt and the OS are clever enough to understand that, but a single slash
looks more nice.
The real problem is the encoding of latex_language: It is hardcoded to latin1,
but InsetListig uses the currently active encoding. Therefore, we cannot tell
whether any given character wil be encodable or not, and we should not prevent
non-ACII characters.
In the future, we need to make the encoding of latex_language dynamic, so that
it always represents the currently active encoding. Then, we could do the
correct check both for listings and ERT. For now, I simply disabled the
encoding check for listings, which also means that bug 9012 might occur in
other cases for listings, but this is less important than bug 9102.
Beamer documents do not have a "--Separator--" layout but a
"Separator" one. Also fix a thinko causing the deletion of
"\end_layout" tags in some cases.
If a separator inset is used after an environment with NextNoIndent
set to false, a blank line was already output. So, avoid outputting
another blank line or an odd looking line with only a '%' character
(as the previous blank line provides already a visual separation).
Multirow cells now have the same alignment rendering in LyX
as in the output. The alignment of a multirow can change as
long as the column is not of fixed width. If the column is
of fixed width, the multirow is left-aligned.
When setting a multirow, the alignment is copied from
the last cell in the selection.
LyX assumes that a standard paragraph following an aligned one or
a layout with NextNoIndent==false has to be indented on screen.
This means that in the latex output a blank line has to follow.
In this case there should be no problem as regards extra vertical
space and it simpler and more elegant to simply uncheck "Indent
Paragraph" in the Paragraph settings pane rather than changing
the current logic and allowing to insert a parbreak separator.
If a layout has NextNoIndent set to true, the following paragraph
is not indented on screen. LyX checks the previous layout for that
style parameter to decide whether to indent or not. Of course,
what matters is the latex output and the on-screen representation
should match this output. Now, when a layout has NextNoIndent==true,
the latex output is correctly not indented, while the on-screen
representation may fail to match this output. This can occur when,
for example, a standard paragraph is nested in the previous layout,
because LyX would check the property of the nested layout instead
of the container layout. Thus, LyX should check the property of a
previous layout at the same depth for correctly deciding whether
a paragraph has to be indented or not.
See also http://www.lyx.org/trac/ticket/9055#comment:12 for an
example document where the previous scenario actually occurs.
With the old code, the last word of a paragraph would not be added in
the completion list. The key difference is to pass `from' instead of `pos'
to FontList::fontiterator.
Slight cleanup of the code.
This was not necessary when LyX was generously outputting newlines.
As it may happen that the output produced by writeExternal (the
result of an external inset) starts right at the beginning of a
line, if otexstream does not know that something is already on
the line, the iomanip-like variable 'breakln' fails to actually
break the line.
This is what LyX was previously doing. It has no effect on vertical
spacing but, for example, sectioning commands stand out on the output.
The parbreak is not output if an environment follows or the alignment
of the current or next paragraph is changed.
Also remove some superfluous code.
The code for detecting python commands and substituting in the
correct prefix is now merged with what used to be libScriptSearch()
and is now renamed to commandPrep(). This commit does not change
any functionality and just improves organization to reduce the
chance of bugs in the future.
Now the replacement is done in startScript(). In addition to making
the code cleaner and more consistent, this commit fixes a bug where
"$$s" was not replaced when "latex=" was specified in the extra flags
of a converter.
Note that the temporary fix at 731b8610 is reverted with this commit.
