* Improve formatting of help descriptions (#213) * new function: cxxopts::Option::set_width(size_t width) Set the size of a helpline. * new function: cxxopts::Option::set_tab_expansion() Expand the tabs in descriptions. The tabsize 8 chars, base is start of description. The descriptions are not disturbed by adding additional options. * Allow newlines \n and tabs \t in descriptions. Other changes (last commit/new commit): * 1453/1471: size_t for OPTION_LONGEST and OPTION_DESC_GAP. This prevents the static cast in 2086/2140. * 2088/2142: in case of small width the value of "width - longest - OPTION_DEC_GAP" becomes negative. Because size_t is unsigned the result is a big number, and the width of the column of the descriptions is not shortened. * new 2143: When the given width is too small, it is set to longest + OPTION_DESC_GAP + 10 * new 1570: A long description is broken into multiple lines, and the iterator lastSpace remembers the begin of the last word. But when the iterator current reaches the end of line, the whole string from iterator is printed, which in soome cases is too long. Thats why one blank is added to the description to trigger the handling of lastSpace. Accordingly in 1574/1627 the line is shortened by one char. * repaired signed/unsigned issue * changes for unicode |
