While there is code in LyX that handles this, tex2lyx should respect
the format that LyX produces and the Flex: prefix is gone since
cfeddb92 in 2014.
In particular, this prefix is known to cause assertion when undoing a
document setting change.
This commit does a bulk fix of incorrect annotations (comments) at the
end of namespaces.
The commit was generated by initially running clang-format, and then
from the diff of the result extracting the hunks corresponding to
fixes of namespace comments. The changes being applied and all the
results have been manually reviewed. The source code successfully
builds on macOS.
Further details on the steps below, in case they're of interest to
someone else in the future.
1. Checkout a fresh and up to date version of src/
git pull && git checkout -- src && git status src
2. Ensure there's a suitable .clang-format in place, i.e. with options
to fix the comment at the end of namespaces, including:
FixNamespaceComments: true
SpacesBeforeTrailingComments: 1
and that clang-format is >= 5.0.0, by doing e.g.:
clang-format -dump-config | grep Comments:
clang-format --version
3. Apply clang-format to the source:
clang-format -i $(find src -name "*.cpp" -or -name "*.h")
4. Create and filter out hunks related to fixing the namespace
git diff -U0 src > tmp.patch
grepdiff '^} // namespace' --output-matching=hunk tmp.patch > fix_namespace.patch
5. Filter out hunks corresponding to simple fixes into to a separate patch:
pcregrep -M -e '^diff[^\n]+\nindex[^\n]+\n--- [^\n]+\n\+\+\+ [^\n]+\n' \
-e '^@@ -[0-9]+ \+[0-9]+ @@[^\n]*\n-\}[^\n]*\n\+\}[^\n]*\n' \
fix_namespace.patch > fix_namespace_simple.patch
6. Manually review the simple patch and then apply it, after first
restoring the source.
git checkout -- src
patch -p1 < fix_namespace_simple.path
7. Manually review the (simple) changes and then stage the changes
git diff src
git add src
8. Again apply clang-format and filter out hunks related to any
remaining fixes to the namespace, this time filter with more
context. There will be fewer hunks as all the simple cases have
already been handled:
clang-format -i $(find src -name "*.cpp" -or -name "*.h")
git diff src > tmp.patch
grepdiff '^} // namespace' --output-matching=hunk tmp.patch > fix_namespace2.patch
9. Manually review/edit the resulting patch file to remove hunks for files
which need to be dealt with manually, noting the file names and
line numbers. Then restore files to as before applying clang-format
and apply the patch:
git checkout src
patch -p1 < fix_namespace2.patch
10. Manually fix the files noted in the previous step. Stage files,
review changes and commit.
Both listings and minted allow for many complex options. So, a latex
source can be easily written as
\documentclass{article}
\usepackage{minted}
\usepackage{graphicx}
\usepackage{dingbat}
\begin{document}
\begin{minted}[breaklines=true,
breakautoindent=false,
breaksymbolleft=\raisebox{0.8ex}{
\small\reflectbox{\carriagereturn}},
breaksymbolindentleft=0pt,
breaksymbolsepleft=0pt,
breaksymbolright=\small\carriagereturn,
breaksymbolindentright=0pt,
breaksymbolsepright=0pt]{Python}
def f(x):
return 'Some text' + str(x) + 'some more text' + str(x) + 'even more text that goes on for a while'
\end{minted}
\end{document}
The used text editor can therefore add a mixture of tabs and spaces.
The white space after the options is not a problem and the imported
file compiles just fine, but the validator gets confused and doesn't
validate them. This would entail a difficult editing of the options
only to have them validated. So, better remove the white space.
This commit updates tex2lyx in order to also import minted listings.
For the floating version of a listing, minted uses the listing
environment, a concept that is not shared with the listings package,
towards which our listings inset is geared.
For this reason, a kludge is necessary when importing minted listings
not previously exported by LyX itself.
If the floating listing contains only a caption and a label (other
than the listing itself), everything is fine and the import is (or
aims to be) perfect. But, as in all other floating ebvironments,
one can also stick there other elements, which don't have a place
in the listings inset. So, in order to avoid a data loss, tex2lyx
sticks everything into the caption. In this way, things may be
rearranged in the GUI, if necessary. There is no other way, apart
from a complete redesign of the listings inset, of course. However,
I think that this is an acceptable compromise.
File format change.
This allows for the relevant InsetCommand-based dialogs (such as
citation text before/after, Bibitem label, hyperlink name etc.)
to provide both the input of verbatim code or text that is transformed
to proper LaTeX code.
Some dialogs (Nomencl, Href) already had some methods (although they
could not be toggled), which are now centralized and streamlined.
The initial work of this patch has been done by Georg Baum (see
http://www.lyx.org/trac/attachment/ticket/2751/x.diff)
Fixes: #2751, #8227.
inset.
If the reference is "sec:mysec", then this will output just "mysec".
This is what is needed, e.g., to use refstyle's range commands, e.g.,
\secrangeref{mysec1}{mysec2}
You *cannot* use:
\secrangeref{sec:mysec1}{sec:mysec2}
even if those are the actual labels.
Eventually, I'd like to add native support for this, but I'm a bit
frightened of trying to make the reference dialog support multiple
selections.
The lib/unicodesymbols part is based on work by Günter Milde:
Both, \r{A} and \AA (rsp. \r{a} and \aa) are equivalent standard LICR macros
for Aring/aring as well as the deprecated "angstrom sign" character (212B).
However, with \AA for 212B and \r{A} for 00C5, tex2lyx converts \AA to the
deprecated "angstrom sign" which is missing in many fonts including the
Unicode version of Latin Modern.
I added the normalize_c() calls so that tex2lyx prefers the precomposed forms
(these are better editable in LyX) and the deprecated flag.
When importing TeX code like
%comment
TEXT
the LyX document currently becomes
[ERT %comment] TEXT
so that TEXT is now part of the comment.
Now output_comment adds a trailing newline if the token after the
comment is not a newline. Note that the newline that marks the end of
the comment has already been parsed at this point.
tex2lyx tests have been checked manually and updated.
Fixes ticket #9551.
The horizontal alignment changes caused a regression for documents in older
formats. This could have been fixed by adding the following lines to the
format entry for 489 in development/FORMAT:
Previously, the horizontal position was ignored except for the
following parameter combinations:
- fixed width and type Boxed and without inner box
- fixed width and any type and with inner box and with makebox
Now, it is also used for the parameter combination below:
- makebox is not used and not (type Boxed and without inner box)
and a corresponding conversion to convert_BoxFeatures() in
lib/lyx2lyx/lyx_2_2.py. However, it was decided to revert the box alignment
changes instead: The box alignment can contradict the paragraph alignment. A
better way to avoid the additional space that can be created by paragraph
alignment (which was the motivation for implementing box alignment) is the
same as for table cells (see noTrivlistCentering() in src/Paragraph.cpp).
This would be a file format change and it is too late now for 2.2.0.
See http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg188147.html for the
complete discussion (subject "Regression in lyx2lyx box alignment").
The correct mappings break the tex2lyx roundtrip tests because both,
the tests and tex2lyx use the wrong mapping (\b for "combining minus below").
Fix tex2lyx and the test files so that round-trip tests pass again.
There are still a few warnings of the kind
(style) Variable 'x' is assigned a value that is never used.
since I did not touch code where I was not sure whether there might be a real
bug, and I kept some for symmetry reasons as well.
These were all flagged by "(style) The scope of the variable 'x' can be reduced."
Narowing the scope improves readability, and if it is in a loop then the
compiler will be clever enough to produce efficient code, we do not need
manual optimization for POD types.
Unfortunately I overlooked in 44f73b065004 that the first three whitespace
changes in box-color-size-space-align.lyx.lyx were actually correct, so they
should not have been reverted. In detail:
1), 2): The space after \raggedleft must not be part of the ERT inset, but it
is ouput by check_space() as part of the standard text which follows.
3): The space in front of www is caused by the fact that there is a
newline between the opening brace of the parbox and the \centering
command, so this space is not the one after \centering (which is
correctly swallowed). This additional space is in fact not needed,
and the contents would look better in LyX without it, but since it is
not caused by special code I'll put it back in the refernce for now.
We can still improve this in the future if anybody has a good idea.
The remaining whitespace issues are all fixed by a simple change in
parse_text(): Instead of always eating whitespace after detecting \centering
et al, and always output a space as part of the ERT if these commands need an
ERT, let the standard space handling mechanism kick in: skip whitespace if
no ERT is used (in this case LyX will always output the needed space), and
do not touch whitespace if an ERT is used.
\framebox{} is equal to \fbox{} and \makebox{} is equal to \mbox{}
When I once wrote this code LyX did not support \fbbox and \mbox and therefore had to use a workaround.
This is the rersult of a discussion on the list. Now all special characters
have meaningful names, and it is clear that the LyX file syntax is not LaTeX.
