| 1242 | * BUGS |
| 1243 | * ---- |
| 1244 | * Known bugs and problems: |
| 1245 | * |
| 1246 | * Redrawing of the main view while loading:: |
| 1247 | * If only part of a commit has been parsed not all fields will be visible |
| 1248 | * or even redrawn when the whole commit have loaded. This can be |
| 1249 | * triggered when continuously moving to the last line. Use 'r' to redraw |
| 1250 | * the whole screen. |
| 1251 | * |
| 1252 | * TODO |
| 1253 | * ---- |
| 1254 | * Features that should be explored. |
| 1255 | * |
| 1256 | * - Proper command line handling; ability to take the command that should be |
| 1257 | * shown. Example: |
| 1258 | * |
| 1259 | * $ tig log -p |
| 1260 | * |
| 1261 | * - Internal command line (exmode-inspired) which allows to specify what git |
| 1262 | * log or git diff command to run. Example: |
| 1263 | * |
| 1264 | * :log -p |
| 1265 | * |
| 1266 | * - Proper resizing support. I am yet to figure out whether catching SIGWINCH |
| 1267 | * is preferred over using ncurses' built-in support for resizing. |
| 1268 | * |
| 1269 | * - Locale support. |
