This change gets teapot to compile without warnings on OpenSUSE Tumbleweed with the extended warnings flags that were recently added. It also represents a more thoroughly (but not exhaustively) tested and debugged version of the expression-controlled style settings from an earlier commit. The facility should be ready for use. It also adds a better pretty-printer for Token values in gdb and extensive edits to the documentation. It fixes a bug in max/min introduced by the addition of the Bool type and the switchover to comparisons returning Bool. It modifies the display of values too long to fit in their cells to show an initial segment of their contents with a continuation mark rather than obscuring the contents completely. Closes #54. Closes #55. Closes #44. Closes #22. Closes #13. |
