| 7 | Can you help this person? Also, can you give me the rest of ledit |
| 8 | to distribute, plus some info on how to use it? |
| 9 | |
| 10 | I have put the files "ledit.l" and "leditcfns.c" on prep:~mdc. |
| 11 | Much to my disgust ledit.l relied on some bogus little package of |
| 12 | functions on HT, so I had to massage it a bit. |
| 13 | |
| 14 | To get it to work, one must: |
| 15 | |
| 16 | - Compile leditcfns.c with something like: |
| 17 | |
| 18 | cc leditcfns.c |
| 19 | |
| 20 | - Edit ledit.l, changing the line beginning "(cfasl" to |
| 21 | have the right pathname for the cfns file you compiled in |
| 22 | the last step. |
| 23 | |
| 24 | - Compile ledit.l with: |
| 25 | |
| 26 | liszt ledit.l |
| 27 | |
| 28 | Then put the following lines in your .lisprc file: |
| 29 | |
| 30 | ;load in functions for emacs interface |
| 31 | (load "//src//mdc//ledit//ledit") ; Location of Ledit library |
| 32 | (set-proc-str "%gnumacs") ; Name of editor |
| 33 | |
| 34 | Then you can use ^E <RETURN> to get from LISP back to gnumacs. |
| 35 | |
| 36 | Here is the part of my .emacs file that pertains to ledit. |
| 37 | |
| 38 | ;;; Set up ledit mode |
| 39 | (setq ledit-go-to-lisp-string "%lisp") |
| 40 | (setq lisp-mode-hook 'ledit-from-lisp-mode) |

| 45 | This is a documentation question. |
| 46 | I cannot figure out how to use Ledit. I suspect I need some |
| 47 | function on the Franz Lisp end of things to go to Emacs and read in |
| 48 | the temporary file. Is this true? Is the Lisp job started within |
| 49 | Emacs or outside of emacs? I'm just plain confused. Perhaps a couple |
| 50 | of words from someone in the know would help. |
| 51 | |
| 52 | A related question. I have been using a shell buffer when interacting |
| 53 | with Lisp (ie. put a definition in the kill buffer and then yank it |
| 54 | into the shell buffer to redefine it). This is nice but tends to fill |
| 55 | up the shell buffer with lots of code (I'd rather keep calls to functions |
| 56 | in the shell and not the functions themselves). |
| 57 | My question: Is using the shell buffer "better" than ledit? Am I using |
| 58 | it in the best way (i.e. copying definitions from an edit buffer to the |
| 59 | shell buffer)? -Thanks, David Neves |
| 60 | |
| 61 | I have found that ledit works well for doing programming development |
| 62 | when you are changing lots of little pieces of a file and don't wish |
| 63 | to recompile the whole file. Of course M-X Compile is very nice for |
| 64 | calling up a liszt on a buffer and watching it in the another window. |
| 65 | Of course the interface of something like NIL is even better because |
| 66 | you can compile your function directly into your lisp. But since NIL |
| 67 | doesn't run under Unix, this is probably the next best thing. |
| 68 | |
| 69 | I have tried the 2 window method (shell in lower window, lisp code in |
| 70 | upper), and have found it a little awkward. It does have certain |
| 71 | advantages, but most of the time, I get be fine using M-C-D to save a |
| 72 | defun for lisp, and C-X Z to jump back to LISP. C-E RETURN from lisp |
| 73 | is also mnemonic for getting back to gnumacs. |
| 74 | |
| 75 | I hope this helps somewhat. |
