The functions were selected from the parser files where document is
always defined.
The only case was this code was used was on document.warning.
Since our documents are well formed this code was never active and thus
the reason why we did not saw this before.
One possible solution to assure that these type of errors do not occur
is to make the convention that all the functions in lyx2lyx_tools have
as the first argument document.
# ambiguous-variable-name (E741)
Derived from the **pycodestyle** linter.
## What it does
Checks for the use of the characters 'l', 'O', or 'I' as variable names.
## Why is this bad?
In some fonts, these characters are indistinguishable from the
numerals one and zero. When tempted to use 'l', use 'L' instead.
## Reason to ignore in LyX?
With appropriated fonts that is not an issue. In our case we just use
the 'l', in particular in the context of iterators: 'i', 'j', 'k', 'l'.
The only difference from regular letter is the alignment of
"Send To Address" layout, but it no longer reflect the output
corrctly, probably because LyX revert the alignment of layouts
in RTL context now.
This is in line with the current hints for better readability:
* one import per line;
* order the imports alphabetically to be easier to search;
Take the chance to remove unused imports.
Remove Python 2 support
This simplifies the code and allows to use other more modern features,
like formatted strings, that were not possible while keeping Python 2
compatibility.
* previwes with xetex did not produce any background (\pagecolor does not work for some reason), adding the direct command for that, \special{background <color>} inside the preview box solved it.
* similar to #12923 we should push the color node in horizontal mode
* there is a bug in preview with LuaTeX with main RTL language, this commit fix this bug, but it should be removed when it is fixed upstream (the code related to \pr@set@pagerightoffset)
- avoid copying of configure.log
- avoid copying of chkconfig.ltx
There is a report of a hang on first start of LyX with new major release.
The removal of the chkconfig.ltx (leftover from early LyX versions) fixed the issue.
