* | If a .shift request has a negative argument, do not use a negative array | Ingo Schwarze | 2022-04-24 | 1 | -2/+6 |
| | | | | | | | | index but use 0 instead of the argument, just like groff. Warn about the invalid argument. While here, fix the column number in another warning message. Segfault reported by tb@, found with afl(1). | ||||
* | Implement the roff(7) .shift and .return requests, | Ingo Schwarze | 2018-08-23 | 1 | -0/+30 |
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(). |
