for an example, when a program reads in a latex source, is there an escape function that can rewrite all `\' to `\\', `"' to `\"', and so on? This kind of escaping for backslash and double-quote (and other chars, depending on Guile flavor) is built-in for ‘(object->string STRING)’, but anything else (the "and so on" bit) you have to define for yourself, or find something already defined. For example, Guile-BAUX provides module ‘(guile-baux write-string)’ which exports proc ‘write-string’ that handles twelve additional characters: http://www.gnuvola.org/software/guile-baux/guile-baux.html.gz#write_002dstring Another example is Guile-PG module ‘(database postgres-qcons)’, which has all manner of procs to DTRT for various "and so on" cases: http://www.nongnu.org/guile-pg/doc/qcons-quoting.html#qcons-quoting I think it would be nice for these procs (and perhaps your LaTeX oriented one, once defined) to be rebased onto a general one, hosted apart from any particular Guile version (perhaps Guile-Lib -- is that project still viable?). Or maybe i'm missing something already out there by now. I remember fruitlessly searching a number of years back, but things may have changed since then.
