<section|Memory management>
|
||
|
|
|
||
|
|
If I have the courage, I might one day write a garbage collector for
|
||
|
|
<TeXmacs>.
|

|
<section|Graphical interface>
|
||
|
|
|
||
|
|
We wish to move towards <with|font-shape|small-caps|Guile-Gtk> or another
|
||
|
|
portable graphical user interface. Now that we have found someone for
|
||
|
|
making a Windows port, this not an urgent issue anymore though.
|
||
|
|
|
||
|
|
<section|Encodings and fonts>
|
||
|
|
|
||
|
|
<\itemize>
|
||
|
|
<item>Systematically use Unicode.
|
||
|
|
|
||
|
|
<item>Some changes have still to be made in the way font encodings are
|
||
|
|
handled. This should make it easier to maintain fonts with characters
|
||
|
|
from several physical fonts, virtual fonts, special characters, etc.
|
||
|
|
|
||
|
|
<item>Currently, the current logical font is determined from a fixed set
|
||
|
|
of environment variables only. The current typesetting font should rather
|
||
|
|
be a tree (instead of a string), which is evaluated (so that environment
|
||
|
|
variables are replaced) and then passed to
|
||
|
|
<verbatim|find_font(display,tree)>. The current font can then be a joined
|
||
|
|
font and future fonts might depend on user environment variables (i.e.
|
||
|
|
colored fonts, using more than one color).
|
||
|
|
</itemize>
|
||
|

|

|
<section|Speed>
|
||
|
|
|
||
|
|
In order to speed up the program, we already made the major change that not
|
||
|
|
the whole document is typeset again when making local changes. However,
|
||
|
|
several other main optimizations should still be made:
|
||
|
|
|
||
|
|
<\itemize>
|
||
|
|
<item>Indexing file names which are in the distribution. This may
|
||
|
|
accelerate booting the program.
|
||
|
|
|
||
|
|
<item>Encode the system environment variables; this will globally
|
||
|
|
accelerate the program. Also, intermediate data during the typesetting
|
||
|
|
process might be encoded in a more binary way.
|
||
|
|
|
||
|
|
<item>The typesetter should be made lazy in a more fundamental way.
|
||
|
|
</itemize>
|
||
|
|
|
||
|
|
<section|Scheme>
|
||
|
|
|
||
|
|
The <name|Guile>/<value|scheme> interface should become more robust and
|
||
|
|
well documented. Several things still need to be done for this:
|
||
|
|
|
||
|
|
<\itemize>
|
||
|
|
<item>Implement a system for ``contextual overloading''.
|
||
|
|
|
||
|
|
<item>Better preservation of locality.
|
||
|
|
|
||
|
|
<item>Systematic use of closures throughout the code.
|
||
|
|
|
||
|
|
<item>A clean interface for manipulating <TeXmacs> content (a unified
|
||
|
|
interface for both internal <TeXmacs> trees and the associated
|
||
|
|
<value|scheme> representation).
|
||
|
|
|
||
|
|
<item>Documentation.
