From a99c9a30e9f41eb3ce553ac0b2ac6ff963ebe49d Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Thu, 23 Aug 2018 14:29:38 +0000 Subject: Implement the roff(7) .shift and .return requests, for example used by groff_hdtbl(7) and groff_mom(7). Also correctly interpolate arguments during nested macro execution even after .shift and .return, implemented using a stack of argument arrays. Note that only read.c, but not roff.c can detect the end of a macro execution, and the existence of .shift implies that arguments cannot be interpolated up front, so unfortunately, this includes a partial revert of roff.c rev. 1.337, moving argument interpolation back into the function roff_res(). --- regress/roff/de/infinite.out_lint | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'regress/roff/de/infinite.out_lint') diff --git a/regress/roff/de/infinite.out_lint b/regress/roff/de/infinite.out_lint index e7beb090..06254be5 100644 --- a/regress/roff/de/infinite.out_lint +++ b/regress/roff/de/infinite.out_lint @@ -1,2 +1,3 @@ -mandoc: infinite.in:14:5: ERROR: input stack limit exceeded, infinite loop? +mandoc: infinite.in:13:9: ERROR: using macro argument outside macro: \$1 +mandoc: infinite.in:14:6: ERROR: using macro argument outside macro: \$1 mandoc: infinite.in:20:5: ERROR: input stack limit exceeded, infinite loop? -- cgit
