Re: [Dev-luatex] Max length of tokens?

Hi, Martin Schröder wrote:

Hi, what's the maximum length of things like \pdfcatalog in luatex (and pdftex)? I.e. how long can a token register get?

For luatex, it was like this: pdf_print_toks_ln(), the function that actually prints token lists to the PDF output, was using pdf_printf(). pdf_printf() was using vsnprintf with a buffer sized PRINTF_BUF_SIZE, and that is where the cut-off came from. I have now changed pdf_print_toks_ln() to use pdf_puts() instead, and have altered pdf_puts() itself to accept arbitrary length strings (it used to be limited by the active PDF buffer size). The commit is #2959 if you want to have a closer look. Best wishes, Taco
