Hi, I am using the Source-highlight library to perform a fairly straightforward syntax highlighting task: given a string containing the source-code, and another with the language definition, I want to return a string with the highlighted version of source-code expressed in a custom "foobar" outlang. In pseudo-C++, something like the code below: (forget optimisations for now) string highlight (string src, string langdef) { istringstream in (src); ostringstream out; SourceHighlight hiliter ("foobar.outlang"); hiliter.highlight (in, out, langdef); return out.str (); } In rough terms, this works. There is however one big problem: any use of escaping directives within the "src" (like "\n") is being processed, instead of being written verbatim into the output string. Is there any way to turn off this behaviour? Thanks in advance! Best regards, Dario Teixeira
Dear DarioI'm not sure I understand what the final result should be, but in the outlang file you can specify some regular expression based translations. For instance, in latex.outlang you have
translations "_" "$\\_$" "{" "\\{" "}" "\\}" "<" "\\textless{}" ">" "\\textgreater{}" "&" "\\&" "\\" "\\textbackslash{}" "^" "\\textasciicircum{}" "~" "\\textasciitilde{}" "\n" " \\\\\n" " " "\\ " "\t" "\\ \\ \\ \\ \\ \\ \\ \\ " "%" "\\%" "#" "\\#" "$" "\\$" "|" "$|$" "---" "-\\/-\\/-" "--" "-\\/-" "\"" "\"{}" # avoids problems with some inputenc end in html_notfixed.outlang translations "\n" "<br>\n" " " " " '^ ' " " # a space at the beginning of a line "\t" " " endso probably you should be able to achieve your goal in your foobar.outlang file.
Please, let me know whether this solves this issue cheers Lorenzo -- Lorenzo Bettini, PhD in Computer Science, DI, Univ.
