Node:Named output formats, Next:Files, Up:Input-Output
The --output-format
(or --format
) command-line switch
can be used to override the default format for how values are
printed on the standard output. This format is used for values printed
by the read-eval-print interactive interface. It is also used to
control how values are printed when Kawa evaluates a file named on the
command line (using the -f
flag or a just a script name).
(It also effects applications compiled with the --main
flag.)
It currently effects how values are printed by a load
,
though that may change.
The default format depends on the current programming language.
For Scheme, the default is --scheme
for read-eval-print
interaction, and --ignore
for files that are loaded.
The formats currently supported include the following:
scheme
display
. "Groups" or "elements" are written as lists.
readable-scheme
scheme
, as if using write
:
Values are generally printed in a way that they can
be read back by a Scheme reader. For example, strings have quotation marks,
and character values are written like #\A
.
elisp
scheme
.
readable-elisp
elisp
, but values are generally printed in a way that they can
be read back by an Emacs Lisp reader. For example, strings have quotation
marks, and character values are written like ?A
.
clisp
commonlisp
princ
.
Mostly the same as scheme
.
readable-clisp
readable-commonlisp
clisp
, but as if written by prin1
: values are generally
printed in a way that they can be read back by a Common Lisp reader.
For example, strings have quotation marks, and character values are
written like #\A
.
xml
<
) are escaped (such as <
).
xhtml
xml
, but follows the xhtml compatibility guidelines.
html
xml
format, but certain element without body,
are written without a closing tag. For example <img>
is written
without </img>
, which would be illegal for html, but required for xml.
Plain characters (such as <
) are not escaped inside <script>
or <style>
elements.
cgi
response-header
function.
If the Content-type
response header has not been specified, and
it is required by the CGI standard, Kawa will attempt
to infer an appropriate Content-ty[e
depending on the following value.
ignore
