@itemize @bullet
|
|
|
|
@item Support other formats than just @LaTeX{}
|
|
|
|
plain @TeX{} users and @ConTeXt{} users should not have to feel left
|
|
out. While @ConTeXt{} is not supported yet by released versions of
|
|
@AUCTeX{}, at least supporting plain would help people, and be a start
|
|
for @ConTeXt{} as well. There are plain-based formats like MusiX@TeX{}
|
|
that could benefit a lot from @previewlatex{}. The main part of the
|
|
difficulties here is to adapt @file{preview.dtx} to produce stuff not
|
|
requiring @LaTeX{}.
|
|
|
|
@item Support nested snippets
|
|
|
|
Currently you can't have both a footnote (which gets displayed as just
|
|
its footnote number) and math inside of a footnote rendered as an image:
|
|
such nesting might be achieved by rerunning @previewlatex{} on the
|
|
footnote contents when one opens the footnote for editing.
|
|
|
|
@item Support other text properties than just images
|
|
|
|
Macros like @samp{\textit} can be rendered as images, but the resulting
|
|
humungous blob is not suitable for editing, in particular since the
|
|
line filling from LaTeX does not coincide with that of Emacs. It would
|
|
be much more useful if text properties just switched the relevant font
|
|
to italics rather than replacing the whole text with an image. It
|
|
would also make editing quite easier. Then there are things like
|
|
footnotes that are currently just replaced by their footnote number.
|
|
While editing is not a concern here (the number is not in the original
|
|
text, anyway), it would save a lot of conversion time if no images were
|
|
generated, but Emacs just displayed a properly fontified version of the
|
|
footnote number. Also, this might make @previewlatex{} useful even on
|
|
text terminals.
|
|
|
|
@item Find a way to facilitate Source Specials
|
|
|
|
Probably in connection with adding appropriate support to
|
|
@code{dvipng}, it would be nice if clicking on an image from a larger
|
|
piece of source code would place the cursor at the respective source
|
|
code location.
|
|
|
|
@item Make @file{preview.dtx} look reasonable in @AUCTeX{}
|
|
|
|
It is a bit embarrassing that @file{preview.dtx} is written in a manner
|
|
that will not give either good syntax highlighting or good indentation
|
|
when employing @AUCTeX{}.
|
|
|
|
@item Web page work
|
|
|
|
Currently, @previewlatex{}'s web page is not structured at all. Better
|
|
navigation would be desirable, as well as separate News and Errata eye
|
|
catchers.
|
|
|
|
@item Manual improvements
|
|
|
|
@itemize @minus
|
|
@item Pepper the manual with screen shots and graphics
|
|
|
|
This will be of interest for the @acronym{HTML} and @TeX{} renditions
|
|
of the texinfo manual. Since Texinfo now supports images as well, this
|
|
could well be nice to have.
|
|
|
|
@item Fix duplicates
|
|
|
|
Various stuff appears several times.

|
@item Implement rendering pipelines for Emacs
|
|
|
|
The current @previewlatex{} interface is fundamentally flawed, not only
|
|
because of a broken implementation. A general batchable and
|
|
daemonizable rendering infrastructure that can work on all kinds of
|
|
preview images for embedding into buffers is warranted. The current
|
|
implementation has a rather adhoc flavor and is not easily extended.
|
|
It will not work outside of @AUCTeX{}, either.
|
|
|
|
@item Integrate into Ref@TeX{}
|
|
|
|
When referencing to equations and the like, the preview-images of the
|
|
source rather than plain text should be displayed. If the preview in
|
|
question covers labels, those should appear in the bubble help and/or a
|
|
context menu. Apropos:
|
|
|
|
@item Implement @LaTeX{} error indicators
|
|
|
|
Previews on erroneous @LaTeX{} passages might gain a red border or similar.
|
|
|
|
@item Pop up relevant online documentation for frequent errors
|
|
|
|
A lot of errors are of the ``badly configured'' variety. Perhaps the
|
|
relevant info pages should be delivered in addition to the error
|
|
message.
|
|
|
|
@item Implement a table editing mode where every table cell gets output
|
|
as a separate preview. Alternatively, output the complete table
|
|
metrics in a way that lets people click on individual cells for editing
|
|
purposes.
|
|
|
|
@item Benchmark and kill Emacs inefficiencies
|
|
|
|
Both the @LaTeX{} run under Emacs control as well as actual image
|
|
insertion in Emacs could be faster. CVS Emacs has improved in that
|
|
respect, but it still is slower than desirable.
|
|
|
|
@item Improve image support under Emacs
|
|
|
|
The general image and color handling in Emacs is inefficient and partly
|
|
defective. This is still the case in CVS. One option would be to
|
|
replace the whole color and image handling with @acronym{GDK} routines
|
|
when this library is available, since it has been optimized for it.
