I see this error each time I use man(1) on other people's MacBooks, and I'm at a loss to explain why:
tbl:<standard input>:2: unrecognised format `o' tbl:<standard input>:2: giving up on this table The tbl markup is valid. In fact, this is all it's given that makes it choke (it was culled down <https://github.com/Alhadis/.files/blob/master/share/man/man5/textmate.5#L368-L492> from a larger table that rendered perfectly fine on my old computer, which had an up-to-date Groff & Co. installed). .TS Scope Description comment For comments .TE Now, we all know Apple are clueless and continue to ship the most ancient versions of software fathomable, but I find it impossible to believe that at some point in Groff's history, there was a published tbl(1) release whose only purpose was to spit confusing error messages, and nothing more. Googling didn't shed insight, and the only result I found <http://mac-os-forge.2317878.n4.nabble.com/man-groff-char-misbehaving-td300532.html> would suggest that the error is Apple-specific. But they didn't know the cause either. For the record, I've ruled out any man.conf settings, because it's happening when I pipe input through the tbl binary directly: λ Desktop: tbl < ./test.1 .if !\n(.g .ab GNU tbl requires GNU troff. .if !dTS .ds TS .if !dTE .ds TE .lf 1 - .TS tbl:<standard input>:2: unrecognised format `o' tbl:<standard input>:2: giving up on this table .lf 4 - .TE λ Desktop: tbl --version GNU tbl (groff) version 1.19.2
