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