|---|---|
| 1 * Define a sentinel function, so that the display doesn't get | |
| 2 screwed up the default sentinel when the process finishes. | |
| 3 | |
| 4 * Performance improvements? (It is zippy enough on reasonably | |
| 5 fast machines, though.) | |
| 6 | |
| 7 * Should more terminal escape sequences be supported? | |
| 8 Yes: At least the ANSI color escapes (as in colour_xterm). | |
| 9 | |
| 10 * The caching variables (e.g. term-current-row) assume that there | |
| 11 is be no random editing of the buffer that we don't know about. In that | |
| 12 respect, they are somewhat fragile. | |
| 13 | |
| 14 * Document the internals better, and make it easier to write | |
| 15 emulators for other kinds of terminals. | |
| 16 | |
| 17 * The scrolling behavior is still not quite right. | |
| 18 | |
| 19 * Stallman has expressed dislike for the xterm style of switching to the | |
| 20 alternate buffer on the "ti" capability. An alternative would be to | |
| 21 defer this until the screen is cleared. That assumes there are programs | |
| 22 that emit ti without following that by a command to erase the window. | |
| 23 I'm not sure there are any such programs (that we care about) ... | |
| 24 | |
| 25 *** CHANGES THAT REQUIRE NEW EMACS PRIMITIVES *** | |
| 26 | |
| 27 * If ioctl is made accessible to elisp, it may be possible | |
| 28 to support some kind of automatic switching between char mode | |
| 29 and line mode. It also becomes possible to privide term | |
| 30 primitives to turn off echoing in the inferior. | |
| 31 | |
| 32 *** CHANGES TO DO IN OTHER PROGRAMS *** | |
| 33 | |
| 34 * In gdb-mode, a keysequence like \C-c\C-s works by sending the command | |
| 35 "step" in gdb-mode. Emacs goes to a fair bit of trouble to delete the | |
| 36 prompt preceding the command, as well as the echo from the inferior. | |
| 37 In addition to being hairy, it is somewhat fragile (because of possible | |
| 38 type-ahead, and because the inferior might be mixing other output with | |
| 39 the echo). | |
| 40 More robust would be for emacs to send the command "noecho step" (or | |
| 41 "step #noecho") where the "noecho" is an instruction to gdb (readline) | |
| 42 to erase the prompt for this command, and suppress its echo. | |
| 43 | |
| 44 * Bash (and perhaps other shells) should be modified so that before | |
| 45 the prompt (and PROMPT_COMMAND) are printed, they emit: | |
| 46 printf("\032/%s\n", PWD); | |
| 47 This will tell the shell window which directory it should assume, | |
| 48 and obviates the need for all that hairy directory tracking. |
