- libevent example
- better example than calculator
- check all XXX in code
- set prompt example
- too much possible completion
- les help() des tokens (string par ex) ne retournent pas "faux" en cas d'erreur
- on pourrait virer la valeur de retour du start() en reorganisant
  cmdline_parse() et cmdline_help()
- genconf: completion des xpath //
- supprimer tous les basic_char_loop()
- possibilité de retourner une erreur dans le parsing (file not found, ...)
- parse(): res ne peut pas etre null pour ipaddr ?
- kill word (alt-bkspace) pourrait s'arreter aux slashs
- rdline: use fopencookies pour le printf ?

buf->linebuf

- rdline: API peut rester comme ca
 doit pouvoir etre utiisé seule
 il fuat un example

- parse:
 doit aussi pouvoir etre utilisé seule
 il faut virer les references a cmdline/rdline

/* opaque is given to the token callback func */
int cmdline_parse(parse_ctx, const char *buf, void *opaque);

/**
 * complete() must be called with an initialized context
 * with *state==-1 (just display choices), then called until it
 * returns CMDLINE_PARSE_COMPLETED_BUFFER or
 * CMDLINE_PARSE_COMPLETE_FINISHED.
 *
 * It returns < 0 on error.
 *
 * Else it returns:
 *   - CMDLINE_PARSE_COMPLETED_BUFFER on completion (one possible
 *     choice). In this case, the chars are appended in dst buffer.
 *   - CMDLINE_PARSE_COMPLETE_AGAIN if there is several possible
 *     choices. In this case, you must call the function again with
 *     the same context
 *   - CMDLINE_PARSE_COMPLETE_FINISHED when the iteration is
 *     finished. The dst is not valid for this last call.
 *
 * The returned dst buf ends with \0.

- cmdline est un assemblage de rdline et parse
  permet de parser des fichiers, de faire un prompt sur stdin, network, unix
