The parseLatex function parses LaTeX source, producing a
structured object; deparseLatex reverses the process. The
latexToUtf8 function takes a LaTeX object, and processes a number
of different macros to convert them into the corresponding UTF-8
characters.
parseLatex(text, filename = deparse1(substitute(text)),
verbose = FALSE,
verbatim = c("verbatim", "verbatim*",
"Sinput", "Soutput"))
deparseLatex(x, dropBraces = FALSE)
latexToUtf8(x)
text |
A character vector containing LaTeX source code. |
filename |
A filename to use in syntax error messages. |
verbose |
If |
verbatim |
A character vector containing the names of LaTeX environments holding verbatim text. |
x |
A |
dropBraces |
Drop unnecessary braces when displaying a |
The parser does not recognize all legal LaTeX code, only relatively simple examples. It does not associate arguments with macros, that needs to be done after parsing, with knowledge of the definitions of each macro. The main intention for this function is to process simple LaTeX code used in bibliographic references, not fully general LaTeX documents.
Verbose text is allowed in two forms: the \verb macro (with
single character delimiters), and environments whose names are listed
in the verbatim argument.
The parseLatex() function returns a recursive object of class
"LaTeX". Each of the entries in this object will have a
"latex_tag" attribute identifying its syntactic role.
The deparseLatex() function returns a single element character
vector, possibly containing embedded newlines.
The latexToUtf8() function returns a modified version of the
"LaTeX" object that was passed to it.
