From aa202260e540ec4a7df78e75b104f0a1c7d0c197 Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Fri, 21 Dec 2018 17:15:18 +0000 Subject: Rename mandoc_getarg() to roff_getarg() and pass it the roff parser struct as an argument such that after copy-in, it can call roff_expand() once again, which used to be called roff_res() before this. This fixes a subtle low-level roff(7) parsing bug reported by Fabio Scotoni in the 4.4BSD-Lite2 mdoc.samples(7) manual page, because that page used an escaped escape sequence in a macro argument. To expand escaped escape sequences in quoted mdoc(7) arguments, too, stop bypassing the call to roff_getarg() in mdoc_argv.c, function args() for this case. This does not solve the case of escaped escape sequences in quoted .Bl -column phrases yet. Because roff_expand() can make the string longer, roff_getarg() can no longer operate in-place but needs to malloc(3) the returned string. In the high-level parsers, free(3) that string after processing it. --- regress/mdoc/Op/arg.out_markdown | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 regress/mdoc/Op/arg.out_markdown (limited to 'regress/mdoc/Op/arg.out_markdown') diff --git a/regress/mdoc/Op/arg.out_markdown b/regress/mdoc/Op/arg.out_markdown new file mode 100644 index 00000000..5ad86f7d --- /dev/null +++ b/regress/mdoc/Op/arg.out_markdown @@ -0,0 +1,21 @@ +OP-ARG(1) - General Commands Manual + +# NAME + +**Op-arg** - escape sequences in the arguments of partial implicit macros + +# DESCRIPTION + +unquoted unescaped: +\[@] + +quoted unescaped: +\[@] + +unquoted escaped: +\[@] + +quoted escaped: +\[@] + +OpenBSD - December 21, 2018 -- cgit
