DESCRIPTION
This manual page may be out of date. Consult the HTML documentation for the most up-to-date information
concerning this program.
Spam (SP Add Markup) is an SGML markup stream editor implemented using the SP parser. Spam parses the
SGML document contained in sysid... and copies to the standard output the portion of the document entity
containing the document instance, adding or changing markup as specified by the -m options. The -p
option can be used to include the SGML declaration and prolog in the output. The -o option can be used
to output other entities. The -x option can be used to expand entity references.
For more information about the underlying SGML parser and entity manager, see nsgmls(1).
The following options are available:
-cfile Use the catalog entry file file.
-Ddirectory
Search directory for files specified in system identifiers. Multiple -D options are allowed. See
nsgmls(1) for more information about file searching.
-e Describe open entities in error messages.
-ffile Redirect errors to file. This is useful mainly with shells that do not support redirection of
stderr.
-h Hoist omitted tags out from the start of internal entities. If the text at the beginning of an
internal entity causes a tag to be implied, the tag will usually be treated as being in that
internal entity; this option will instead cause it to be treated as being in the entity that
referenced the internal entity. This option makes a difference in conjunction with -momittag or
-x -x.
-iname Pretend that
<!ENTITY % name "INCLUDE">
occurs at the start of the document type declaration subset in the document entity.
-l Prefer lower-case. Added names that were subject to upper-case substitution will be converted to
lower-case.
-mmarkup_option
Change the markup in the output according to the value of markup_option as follows:
omittag
Add tags that were omitted using omitted tag minimization. End tags that were omitted
because the element has a declared content of EMPTY or an explicit content reference will
not be added.
shortref
Replace short references by named entity references.
net Change null end-tags into unminimized end-tags, and change net-enabling start-tags into
unminimized start-tags.
emptytag
Change empty tags into unminimized tags.
unclosed
Change unclosed tags into unminimized tags.
attname
Add omitted attribute names and vis.
attvalue
Add literal delimiters omitted from attribute values.
attspec
Add omitted attribute specifications.
current
Add omitted attribute specifications for current attributes. This option is implied by the
attspec option.
shorttag
Equivalent to combination of net, emptytag, unclosed, attname, attvalue and attspec
options.
rank Add omitted rank suffixes.
reserved
Put reserved names in upper-case.
ms Remove marked section declarations whose effective status is IGNORE, and replace each
marked section declaration whose effective status is INCLUDE by its marked section. In the
document instance, empty comments will be added before or after the marked section
declaration to ensure that ignored record ends remain ignored.
Multiple -m options are allowed.
-oname Output the general entity name instead of the document entity. The output will correspond to the
first time that the entity is referenced in content.
-p Output the part of the document entity containing the SGML declaration (if it was explicitly
present in the document entity) and the prolog before anything else. If this option is specified
two or more times, then all entity references occurring between declarations in the prolog will be
expanded; this includes the implicit reference to the entity containing the external subset of the
DTD, if there is one. Note that the SGML declaration will not be included if it was specified by
an SGMLDECL entry in a catalog.
-r Don't perform any conversion on RSs and REs when outputting the entity. The entity would
typically have the storage manager attribute records=asis.
-v Print the version number.
-wtype Control warnings and errors according to type. See nsgmls(1) for the allowed values of type.
-x Expand references to entities that are changed. If this option is specified two or more times,
then all references to entities that contain tags will be expanded.
BUGS
Omitted tags are added at the point where they are implied by the SGML parser (except as modified by the
-h option); this is often not quite where they are wanted.
The case of general delimiters is not preserved.
Incorrect results may be produced if a variant concrete syntax is used which is such that there are
delimiters in markup to be added that have a prefix that is a proper suffix of some other delimiter.
If an entity reference in a default value uses the default entity and an entity with that name is
subsequently defined and that default value is added to the document instance, then the resulting
document may not be equivalent to the original document. Spam will give a warning when the first two
conditions are met.
