more efficient
local rep = lpeg.replacer {
{ '{', '{\\textbraceleft}' },
{ '}', '{\\textbraceright}' },
{ '#', '{\\texthash}' },
{ '$', '{\\textdollar}' },
{ '&', '{\\textampersand}' },
{ '%', '{\\textpercent}' },
{ '\\','{\\textbackslash}' },
{ '|', '{\\textbar}' },
{ '_', '{\\textunderscore}' },
{ '~', '{\\textasciitilde}' },
{ '^', '{\\textasciicircum}' },
{ '"', "\"&ditto&\"" },
}
function doubleQuotableEscapedConTeXtString( str)
return rep:match(str)
end
this is probably also ok:
local rep = {
["\""] = "\\char34 ",
["#"] = "\\char35 ",
["$"] = "\\char36 ",
["%"] = "\\char37 ",
["&"] = "\\char38 ",
["\\"] = "\\char92 ",
["^"] = "\\char94 ",
["_"] = "\\char95 ",
["{"] = "\\char123 ",
["|"] = "\\char124 ",
["}"] = "\\char125 ",
["~"] = "\\char126 ",
}
function doubleQuotableEscapedConTeXtString(str)
return (string.gsub(str,".",rep))
end
