| Title: | Generalized Label Formatting |
|---|---|
| Description: | The 'spork' syntax describes label formatting concisely, supporting mixed nesting of subscripts and superscripts to arbitrary depth. It intends to be easy to read and write in plain text, and easy to convert to equivalent presentations in 'plotmath', 'latex', and 'html'. Greek symbols and a multiplication symbol are explicitly supported. See ?as_spork and ?as_previews. |

Converts one spork to html.
See description for as_spork.
By default, unrecognized tokens are returned
literally. However, Greek symbols and html
metacharacters are escaped.
See htmlToken.

Experimental support is implemented for
the newline character ('\n').
Default behavior is to introduce literal
newline characters into the resulting
tex. This may have no effect on the
typeset result. It may be possible
to achieve other effects by using
non-default values of helper arguments
and perhaps additional latex packages.

Experimental support is implemented for
the sequence "backslash n" ('\n').
It tries to break the expression at the
point indicated, and stack the results.
Active subscripts and superscripts
are closed in advance, preventing
these from breaking across lines.

Parses spork. Converts length-one character
to vector of tokens. Explicit tokens include
*._^ and any of these escaped with
backslash, e.g. '\*'.
Backslash-n is an explicit token ('\n').
Backslash-backtick is an explicit token ('\`').
One or more consecutive whitespace characters are a single token,
as are one or more consecutive octothorpes (#).
Any string of characters delimited by
one or more of the above is implicitly
a token as well. As of version 0.2.6,
supported names of Greek letters are
tokens (see greek) possibly
bounded by backticks (to be interpreted literally).
