Summary: tbl reports incorrect line numbers in diagnostics
Project: GNU troff

Category: Preprocessor tbl
Severity: 3 - Normal
Item Group: Incorrect behaviour
Status: In Progress
Privacy: Public

Discussion Lock: Any
Planned Release: None
_______________________________________________________
Details:
...sometimes.
Namely, when input line continuation (\RET) is used inside the table.
Reproducer:
$ nl reproducer.roff
1 .TS
2 l l.
3 foo bar
4 baz qux\
5 fnord
6 baz qux\
7 fnord
8 .TE
$ tbl reproducer.roff >/dev/null
tbl:reproducer.roff:4: excess data entry 'fnord' discarded
tbl:reproducer.roff:5: excess data entry 'fnord' discarded
Fortunately, I have a fix.
$ ./build/tbl reproducer.roff >/dev/null
./build/tbl:reproducer.roff:4: error: line continuation escape at line 4
./build/tbl:reproducer.roff:5: error: excess data entry 'fnord' discarded
./build/tbl:reproducer.roff:6: error: line continuation escape at line 6
./build/tbl:reproducer.roff:7: error: excess data entry 'fnord' discarded
I'll be getting rid of those "line continuation escape" diagnostics before
committing.
