|
* fragment of a columnar list (`Bl -tag' or `Bl -column'), which does |
|
* not have a trailing newline. |
|
* |
|
* The following flags may be specified: |
|
* |
|
* - TERMP_NOLPAD: when beginning to write the line, don't left-pad the |
|
* offset value. This is useful when doing columnar lists where the |
|
* prior column has right-padded. |
|
* |
|
* - TERMP_NOBREAK: this is the most important and is used when making |
|
* columns. In short: don't print a newline and instead pad to the |
|
* right margin. Used in conjunction with TERMP_NOLPAD. |
|
* |
|
* - TERMP_TWOSPACE: when padding, make sure there are at least two |
|
* space characters of padding. Otherwise, rather break the line. |
|
* |
|
* - TERMP_DANGLE: don't newline when TERMP_NOBREAK is specified and |
|
* the line is overrun, and don't pad-right if it's underrun. |
|
* |
|
* - TERMP_HANG: like TERMP_DANGLE, but doesn't newline when |
|
* overruning, instead save the position and continue at that point |
|
* when the next invocation. |
|
* |
|
* In-line line breaking: |
|
* |
|
* If TERMP_NOBREAK is specified and the line overruns the right |
|
* margin, it will break and pad-right to the right margin after |
|
* writing. If maxrmargin is violated, it will break and continue |
|
* writing from the right-margin, which will lead to the above scenario |
|
* upon exit. Otherwise, the line will break at the right margin. |
