|
.Pp |
|

|
.D1 Ar file : line : column : \ level : |
|
.Sm on |
|
.Pp |
|
where the fields have the following meanings: |
|
.Bl -tag -width "column" |
|
.It Ar file |
|
The name of the input file causing the message. |
|
.It Ar line |
|
The line number in that input file. |
|
Line numbering starts at 1. |
|
.It Ar column |
|
The column number in that input file. |
|
Column numbering starts at 1. |
|
If the issue is caused by a word, the column number usually |
|
points to the first character of the word. |
|
.It Ar level |
|
The message level, printed in capital letters. |
|
.El |
|
.Pp |
|
Message levels have the following meanings: |
|
.Bl -tag -width "warning" |
|
.It Cm fatal |
|
The parser is unable to parse a given input file at all. |
|
No formatted output is produced from that input file. |
|
.It Cm error |
|
An input file contains syntax that cannot be safely interpreted, |
|
either because it is invalid or because |
|
.Nm |
|
does not implement it yet. |
|
By discarding part of the input or inserting missing tokens, |
|
the parser is able to continue, and the error does not prevent |
|
generation of formatted output, but typically, preparing that |
|
output involves information loss, broken document structure |
|
or unintended formatting. |
|
.It Cm warning |
|
An input file uses obsolete, discouraged or non-portable syntax. |
|
All the same, the meaning of the input is unambiguous and a correct |
|
rendering can be produced. |
|
Documents causing warnings may render poorly when using other |
|
formatting tools instead of |
|
.Nm . |

The |

input files cannot be read. |
