92: * Flush a line of text. A "line" is loosely defined as being something
93: * that should be followed by a newline, regardless of whether it's
94: * broken apart by newlines getting there. A line can also be a
95: * fragment of a columnar list.
96: *
97: * Specifically, a line is whatever's in p->buf of length p->col, which
98: * is zeroed after this function returns.
99: *
1.84 kristaps 100: * The usage of termp:flags is as follows:
1.71 kristaps 101: *
102: * - TERMP_NOLPAD: when beginning to write the line, don't left-pad the
103: * offset value. This is useful when doing columnar lists where the
104: * prior column has right-padded.
105: *
106: * - TERMP_NOBREAK: this is the most important and is used when making
107: * columns. In short: don't print a newline and instead pad to the
108: * right margin. Used in conjunction with TERMP_NOLPAD.
109: *
1.91 kristaps 110: * - TERMP_TWOSPACE: when padding, make sure there are at least two
111: * space characters of padding. Otherwise, rather break the line.
112: *
1.84 kristaps 113: * - TERMP_DANGLE: don't newline when TERMP_NOBREAK is specified and
114: * the line is overrun, and don't pad-right if it's underrun.
115: *
116: * - TERMP_HANG: like TERMP_DANGLE, but doesn't newline when
117: * overruning, instead save the position and continue at that point
118: * when the next invocation.
1.71 kristaps 119: *
120: * In-line line breaking:
121: *
122: * If TERMP_NOBREAK is specified and the line overruns the right
123: * margin, it will break and pad-right to the right margin after
124: * writing. If maxrmargin is violated, it will break and continue
1.114 kristaps 125: * writing from the right-margin, which will lead to the above scenario
126: * upon exit. Otherwise, the line will break at the right margin.
