!Important Changes in LyX 2.4.0
|
||||
|
||||
|
||||
!!Interface changes
|
||||
|
||||
* LyX now has "inverted" branch insets, which output their contents just in
|
||||
case a given branch is not "activated". This makes inclusion of alternate
|
||||
material in different versions easier.
|
||||
|
||||
* When inserting a command or symbol in mathed, it is now automatically
|
||||
wrapped in a real inset (either \text or \ensuremath) assuring the correct
|
||||
mode, instead of being wrapped only in the output. The wrapping inset can
|
||||
be safely dissolved, as it will be automatically inserted at export time
|
||||
if needed, as usual.
|
||||
|
||||
* LyX now outputs en- and em-dashes as -- and --- ligatures when exporting to
|
||||
latex using TeX fonts, as done in version 2.1 and earlier. In version 2.2
|
||||
they were instead output as the macros \textendash and \textemdash, causing
|
||||
changed output with old documents and bugs. The 2.2 behavior can be restored
|
||||
by don't allowing using dash ligatures in Document->Settings->Fonts.
|
||||
|
||||
* The following UI translations were dropped, because the lack of translation
|
||||
maintenance: Russian, Danish, Greek, Serbian, Galician, Catalan, Romanian,
|
||||
Dutch.
|
||||
|
||||
!!Documents compilation process and images conversion
|
||||
|
||||
* The converters definition syntax (LYX_HOME/lyxrc*) now supports a
|
||||
new option, 'needauth', to prevent completely automated execution of
|
||||
the converter, unless LyX acquired explicit consent by the
|
||||
user. This is a new security feature, useful for converters that are
|
||||
capable of executing arbitrary code, such as R scripts (used with
|
||||
sweave/knitr), embedded within LyX documents. The user needs to
|
||||
explicitly grant per-document permission on the first need for using
|
||||
the converter on each document, unless he/she checks the "Don't ask
|
||||
again for this document" checkbox in the permission dialog. The new
|
||||
behavior can be fine-tuned from two new options in the preferences
|
||||
dialog (see their description below). These also allow for disabling
|
||||
'needauth' converters altogether, if desired (default behavior).
|
||||
|
||||
* LyX now supports insertion and automated conversion of Gnuplot scripts,
|
||||
recognized by their typical extension ".gp" or ".gnuplot". These can
|
||||
directly be inserted in a LyX document using the "Insert->Graphics..."
|
||||
dialog, then selecting the Gnuplot script. LyX automatically adds a
|
||||
proper "set terminal ..." and "set output ..." line to convert the
|
||||
file to the needed output format (e.g., .eps, .pdf), depending on
|
||||
whether the document is being previewed on screen or compiled as PDF
|
||||
or other formats. Terminal options cannot be fine-tuned at the moment,
|
||||
but that's a capability that may come soon, also according to the
|
||||
received feedback from users.
|
||||
|
||||
|
||||
!!!The following pref variables were added in 2.3:
|
||||
|
||||
* \use_converter_needauth
|
||||
when enabled, user is asked before calling any (possibly dangerous)
|
||||
external converter with the 'needauth' option
|
||||
|
||||
* \use_converter_needauth_forbidden
|
||||
when enabled, use of external converters with the 'needauth' option is
|
||||
forbidden
|
||||
|
||||
* \pygmentize_command
|
||||
holds the name of the driver command used by the Pygments python module.
|
||||
|
||||
* \default_platex_view_format
|
||||
Determine the default output format for Japanese documents that use the
|
||||
pLaTeX backend [default: "pdf3" == "PDF (dvipdfm)"]

* \use_qimage
|
||||
This is no longer necessary due to the rewrite of the painter.
|
||||
|
||||
|
||||
!!!The following new LyX functions have been introduced in 2.3:
|
||||
|
||||
* buffer-zoom
|
||||
Zooms the screen fonts to a given value or resets to the default zoom
|
||||
when no argument is given.
|
||||
|
||||
* branch-invert
|
||||
Toggles inversion status of branch inset.
|
||||
|
||||
* lyx-activate
|
||||
Activates the LyX window. Useful in combination with reverse search.
|
||||
|
||||
* devel-mode-toggle
|
||||
Activate/deactivate the developer mode, which consists mainly in:
|
||||
(1) more information shown in the status bar and (2) help file
|
||||
opened in editable mode. This state used to be hardcoded at compile
|
||||
time.
|
||||
!!!The following new LyX functions have been introduced in 2.4:
|
||||
|
||||
|
||||
!!!The following LyX functions have been changed in 2.3:
|
||||
|
||||
* quote-insert
|
||||
The function now has a second and third optional argument to specify
|
||||
the side (left, right, auto) and quotation mark style (english, swedish,
|
||||
german, polish, french, danish).
|
||||
!!!The following LyX functions have been changed in 2.4:
|
||||
|
||||
* inset-modify
|
||||
This function now also applies to quote insets. It takes a three-character
|
||||
string as an argument, referring (1.) to the style (e = ``english'',
|
||||
s = ''swedish'', g = ,,german``, p = ,,polish'', f = <<french>>, a = >>danish<<),
|
||||
(2.) to the side (l = left, r = right) and (3.) to the quotation level
|
||||
(s = single, d = double). So "eld" means "English left double quotation mark".
|
||||
A dot in the string means: take the current value. So "inset-modify changetype e.."
|
||||
will only change the style to English, while letting side and level as is,
|
||||
"inset-modify changetype f.s" will change the style to French and the level to
|
||||
single, leaving the side value.
|
||||
|
||||
This function is most useful when combined with inset-forall. E.g.,
|
||||
"inset-forall Quotes inset-modify changetype f.."
|
||||
=> change all quote insets to French style, maintaining current side and level
|
||||
"inset-forall Quotes inset-modify changetype ..s"
|
||||
=> change all quote insets to single quotes, keeping style and level
|
||||
"inset-forall Quotes inset-modify changetype g.s"
|
||||
=> change all quote insets to German single quotes, keeping left/right setting
|
||||
|
||||
* word-delete-forward, word-delete-backward, char-delete-forward,
|
||||
char-delete-backward
|
||||
The pre-2.3 behavior of these functions is equivalent to the 2.3 behavior with
|
||||
the "force" option appended. The new default behavior (without "force") is
|
||||
to select big insets on the first call and delete them only on the second.
|
||||
This new behavior is consistent with how delete works in LyX's math editor.

!!!The following LyX documents have been moved in 2.3:
|
||||
|
||||
|
||||
!!!The following new folders have been added to the LyX directory
|
||||
|
||||
* citeengines: Contains the *.citeengine files that determine the citation
|
||||
formatting and features.
|
||||
|
||||
* xtemplates: Contains the *.xtemplate files that define the external templates
|
||||
(previously in the external_templates file).
|
||||
|
||||
|
||||
!!!The following preferences files have been removed from the tarball in 2.3:
|
||||
|
||||
* external_templates. This files has been split into multiple *.xtemplate
|
||||
files that are now shipped as content of the xtemplates directory.
|
||||
!!!The following preferences files have been removed from the tarball in 2.4:
|
||||
|
||||
|
||||
!!!The following metadata files have been added to the tarball in 2.3:

|
||||
|
||||
!!Changes with respect to external programs and libraries in 2.3:
|
||||
|
||||
* Inkscape SVG with separate LaTeX + PDF output is experimentally supported.
|
||||
|
||||
* Add some editor/viewer applications to (re)configure checks.
|
||||

|
||||
|
||||
* The external_templates file has been split into one file per template,
|
||||
which are now located in lib/xtemplates/*.xtemplate. This makes it easier
|
||||
to add new templates or modify existing ones. If you have modified
|
||||
the external_templates file, you will have to move the modifications to
|
||||
the respective *.xtemplate file manually.
|
||||
|
||||
* If using TeX fonts and en- and em-dashes are output as font ligatures,
|
||||
when exporting documents containing en- and em-dashes to the format of
|
||||
LyX 2.0 or earlier, the following line has to be manually added to the
|
||||
unicodesymbols file of that LyX version:<br>
|
||||
0x200b "\\hspace{0pt}" "" "" "" "" # ZERO WIDTH SPACE<br>
|
||||
This avoids "uncodable character" issues if the document is actually
|
||||
loaded by that LyX version. LyX 2.1 and later versions already have the
|
||||
necessary definition in their unicodesymbols file.
|
||||
|
||||
* If trying to compile documents using R scripts and sweave/knitr, LyX
|
||||
2.3.x would not allow for re-running the R scripts, unless the user:
|
||||
1) explicitly disables the "Forbid use of needauth converters"
|
||||
option in the LyX preferences;
|
||||
2) provides explicit consent to the use of the converter on the first
|
||||
compilation of the R-enhanced document.
|
||||
|
||||
* LyX now gives a warning if a document mixes title and non-title layouts.
|
||||
In some cases, this warning is harmless, but in other cases the document has
|
||||
a serious problem even though the LaTeX command does not exit with error. For
|
||||
example, create a document with a title layout, then a standard layout, and
|
||||
then an author layout, and you will see in the PDF that the author is not
|
||||
typeset as an author.
