<tmdoc-title|<value|scheme> serialization>
|
||
|
|
|
||
|
|
Users may write their own extensions to <TeXmacs> in the <value|scheme>
|
||
|
|
extension language. In that context, <TeXmacs> trees are usually
|
||
|
|
represented by <value|scheme> expressions. The <value|scheme> syntax was
|
||
|
|
designed to be predictable, easy to hand-edit, and expose the complete
|
||
|
|
internal structure of the document. For instance, the formula
|
||
|
|
(<reference|tm-tree-ex>) is represented by
|
||
|
|
|
||
|
|
<\tm-fragment>
|
||
|
|
<verbatim|(with "mode" "math" (concat "x+y+" (frac "1" "2") "+" (sqrt
|
||
|
|
"y+z")))>
|
||
|
|
</tm-fragment>
|
||
|
|
|
||
|
|
The <value|scheme> representation may also be useful in order to represent
|
||
|
|
complex macros with a lot of programmic content. Finally, <value|scheme> is
|
||
|
|
the safest format when incorporating <TeXmacs> snippets into emails.
|
||
|
|
Indeed, both the standard <TeXmacs> format and the XML serialization may be
|
||
|
|
quite sensitive to white-space.
|
||
|
|
|
||
|
|
In order to save or load a document in <value|scheme> format, you may use
|
||
|
|
<menu|File|Export|Scheme> <abbr|resp.> <menu|File|Import|Scheme>. Files
|
||
|
|
saved in <value|scheme> format can easily be processed by external
|
||
|
|
<value|scheme> programs, in the same way as files saved in XML format can
|
||
|
|
easily be processed by tools for processing XML, like XSLT.
|
||
|
|
|
||
|
|
In order to copy a document fragment to an email in <value|scheme> format,
|
||
|
|
you may use <menu|Edit|Copy to|Scheme>. Similarly, you may paste external
|
||
|
|
<value|scheme> fragments into <TeXmacs> using <menu|Edit|Paste
|
||
|
|
from|Scheme>. The <value|scheme> format may also used interactively inside
|
||
|
|
<value|scheme> sessions or interactive commands. For instance, typing
|
||
|
|
<shortcut|(interactive exec-interactive-command)> followed by the interactive command
|
||
|
|
|
||
|
|
<\scheme-fragment>
|
||
|
|
(insert '(frac "1" "2"))
|
||
|
|
</scheme-fragment>
|
||
|
|
|
||
|
|
inserts the fraction <frac|1|2> at the current cursor position.
