Re: Editors compendium & sam

[hc05@summitis.com]

Thanks for the replies so far on the editor compendium.  I'll respond to both
Erik & Rob here.  A few of the suggestions don't work in all situations, so 
we'll have to decide how to state them.

Good, but it won't work on the first line, if this matters.

>>Goto begin next line: ?

This doesn't work if you are at the beginning of a line.  How about just /^/

Agreed.

This selects the previous and current lines.

Of course!

You can use the mouse to move the current line to the top of the screen, but
there is not a simple way to move the current line to the middle or bottom,
short of a bunch of trial-and-error clicks, unless there is something I am
missing.

Good.  I'll have to remember this.

I agree, since sam has almost no features and almost infinite capabilities.

I looked at the compendium again, and found a better choice than to say macros,
which is to use the following, so I will substitute this wherever I said macro.

     ^     The editor does not have a specific command to do this, but
           it can be very easily done with a couple of keystrokes.
           I.e.  Clear buffer may be implemented as:
                     select buffer contents command,
                     delete selection.

The compendium does have one item as being implemented with a macro, which is
"Spell check select text".  I did this with an external script that I wrote
that is a front end to ispell, but this should go in the filter category in
the compendium rather than as a macro.

This highlights the next line.

>+

>-

This highlights the previous line.

Good question.  I just looked, and I got the tag program with the samx
extensions, which I am not counting here, although I couldn't live without
them.

Is acid available for UNIX?  This does make me realize that I should add Plan 9
to the OS list.

Agreed.  Also, I've found regular expressions to convey the C constructs I care
about.

This one could be a yes.  It depends on what they mean.  This command selects
the last occurrence in the selected region, which may be fine.

Its not my typo. I cut & pasted it from the compendium.


oh yes, i missed the 'begin' :


>Goto begin next line: ?
+0+#0

Good, but it won't work if you are at the beginning of a line.

>Goto begin prev line: ?
-0-#0

Good, but it won't work if you are at the beginning of a line.
