The current working buffer may be changed (with a call to `set-buffer',
|
|
|
|
or with \\[ielm-change-working-buffer]), and its value is preserved between successive
|
|
|
|
evaluations. In this way, expressions may be evaluated in a different
|
|
|
|
buffer than the *ielm* buffer. By default, its name is shown on the
|
|
|
|
mode line; you can always display it with \\[ielm-print-working-buffer], or the buffer itself
|
|
|
|
with \\[ielm-display-working-buffer].

During evaluations, the values of the variables `*', `**', and `***'
|
|
|
|
are the results of the previous, second previous and third previous
|
|
|
|
evaluations respectively. If the working buffer is another IELM
|
|
|
|
buffer, then the values in the working buffer are used. The variables
|
|
|
|
`*1', `*2' and `*3', yield the process buffer values.
|
|
|
|
|
1994-05-02 17:13:42 +00:00

Expressions evaluated by IELM are not subject to `debug-on-quit' or

`debug-on-error'.

|
|
|
* To stop beeping on error, set `ielm-noisy' to nil.

|

* If you don't like the prompt, you can change it by setting `ielm-prompt'.
|
2004-04-24 22:58:40 +00:00
|
|
|
* If you do not like that the prompt is (by default) read-only, set
|
|
|
|
`ielm-prompt-read-only' to nil.
|
2004-04-23 21:33:38 +00:00
|
|
