The code is (much) smaller than +this man page. +.Sh SEE ALSO +.Xr diff 1 , +.Xr less 1 . +.Sh BUGS +.Nm +assumes standard ANSI color escape sequences (as used by xterm and most other +commonly used terminals), rather than using +.Xr curses 3 . + +.Nm +should really be a large and complex C program based on +.Xr less 1 +and a diff library. This would allow a more informative display, including +collapsing pure deletions/insertions inside a single line to one line with +colors for deleted/added material, avoiding the line-wrap problems in less +due to less not knowing the effects or lengths of the color escape codes, +and correct handling of shifted tabs (instead of just expanding them to +spaces.) |
