[9fans] acme/sam linewrapping off

Hi all,

Is there any way how to sensibly edit a file with long lines (eg. a table
with many fields, like /sys/lib/lp/devices) using acme/sam? What I miss is a
way to not wrap long lines when I need to concentrate
on the different fields and a whole
single line is a true representative of an item (a printer).

Thanks

make the frame long enough to hold the whole line.

for example in acme, use a single column display and a tiny font.  you
can get one by middle clicking on this

	Font /lib/font/bit/misc/ascii.5x7.font

Thanks for the answer, although it did not please me... :(
(In Vim, you only have to do :set nowrap and you are done... From time to
time I find this rather useful.)

it's unreasonable for the lp configuration file to need lines 200 characters long.
i would think it would make more sense to talk about addressing lp's unreasonable
requirments rather than complaining about acme's lack of features.

Well, what you are saying is usually true (that line lengths should usually
not be too long). I mentioned the lp configuration file as an example (a
particular one, thought, since there it was that I encountered the problem).
Nonetheless, even if I had only a reasonable number of fields (say 5) and I
had the field names (string comments) above the real
field values, it could easily happen the lines would be wrapped if my
window weren't big enough. The
same happens even when viewing an ordinary program code, if the window is
not large enough. Adjusting the window size or font size
is one way to go, however, why should I be forced to do it, when it's by no
way neccessary, had I the option to not wrap... All I want to see are the
beginings of lines and should I decide to edit a particular line I had no
problem moving to it and edit it.

Another, even more compelling example is, when you want to look at some
scientific data from some experiment. There it is quite common to have rows
of data, each row having say 20 real
numbers, each row meaning one 'step' of the experiment. With acme or sam,
with/without your solution, you have no simple way of looking at it. Using
Vim, it's an easy task, you can turn the wrapping off...

I tend to think editing tabular data is a task for a different
program.  20 real numbers of a similar length are probably fine in
Vim.  But throw in a couple of fields where the length varies and
keeping track of columns across lines gets to be a real task, wrapping
or no.  I'd like to see an acme-like environment for editing tables.
(I know, "Quit talking; start coding.")

Maybe there's someone out there who has done a spreadsheet for Plan 9?

I've never looked, are there any open source spreadsheets around that would lend
themselves as a starting point?

I understand that a speadsheet would solve the situation, but...
Vim has always been sufficient for the task I described, having that one
particular feature.
If acme were able of the same, it would suffice me as well...

Hi,

Well, vim@plan9 could definitely be a choice. But, doesn't it go against the
basic philosophy of Plan9 creators??!

Sam, as far as I know, was created with orthogonality and simplicity in mind
(as well as whole Plan9). It only added a few commands compared to ed. Just
what is truly needed. Vim is highly configurable, any instance of it behaves
slightly differently, and it has incomparably higher complexity, which makes
it, some would say (read E. S. Raymond's Art of unix) awful. We parhaps
really don't need that. But nowadays, you don't have a choice: neither sam
nor acme can be used.

the response here usually follows these steps:

(1) at most a mild suggestion to try using the system somewhat as intended
(2) ignoring it

this is in contrast to affirmative-action companies such as Apple, where
a port of Vim to the iPhone and Touch would quickly be sensed by the
caveman intrusion detection system,
and Jobs would soon turn up to shame the ingrate in public,
and rip the device from those cheating hands.

I haven't said that to use Vim is bad. Vim is my most favourite editor. I am
myself happy to have Vim around in Plan9 (and am not alone for sure).
Nonetheless, it's bad to not have an alternative which would follow the
system's principles. Please read all I mentioned before. Vim does not follow
those and is more and more distant from them (adding more and more features,
becoming bloated). But now, there is not a Plan9-like editor suited for
editing e.g. aforementioned files with several (real-number) fields (it
simply gets wrapped and is unreadable then; using small fonts is not a
proper solution since a too small font renders the file unreadable again).
To be forced to use Vim right away is in my opinion sad. (Opposite to what
you propose: you have to use Vim, you have no other way == you can't ignore
it.)

why don't you add this feature to acme?  you have the source.  you care about
this feature.

I just love this switch... :)
In my opinion, before you start implementing anything (if it's not trivial),
you should be well convinced about its usefulness. This has two points.
First you should find if your task can't be done in another, possibly better
way (use another program, use already existing and known trick), and second,
you should not do something others have already solved.
Until now, people who answered me in this list proposed no good solution.
Others agued my problem is not an issue. For the latter I tried to lay down
some reasons why I think, it is an issue. Hopefully clearly enough. So first
I wanted to see that nobody here can give me a satisfactory solution. This
has been actually happening.
Only then I can think how much work it would be for me to add the feature.
Since I am a physicist and a beginner in Plan9, I can't do it straight away,
maybe in a few weeks time. But I know at least now, that  first, it would be
useful to add it (nobody has done it yet), and second, that I just can't use
Plan9 for my real job now.

If I code it, I will let you know.

Who cares? I talked to one of those creators @ google a little while
back. In response to some of my probing on "what if we change this" he
said, "well, we're pretty much out of it, you can do what you deem
necessary".

Sure, there are a few rules you ought to follow. Don't go the path of
Linux and add a system call every time you need something new. But,
the code is not Holy Writ. It's code. Change it and learn.

Re: [9fans] acme/sam linewrapping off

[Skip Tavakkolian]

have you considered using sam to break each line into multiple lines
and then rejoining.  e.g. if you have a | separated record structure, you
could do something like:

,x/^.*\n/ {
s/\|/\n/g
s/\n/\n\n/
}

edit the fields, then rejoin before writing it back:

,y/\n\n/ x/\n/ c/|/
,x/\n\n/ c/\n/

fyi, i'm a casual sam user and there are probably better ways.

Re: [9fans] acme/sam linewrapping off

[gdiaz]

Hola,

i think you can take other approaches to solve your problems instead of using vim, or making acme behave like vim.

see what others have done with acme:

http://plan9.bell-labs.com/iwp9/papers/20.acme-trans.pdf

may be that could give you more ideas, other perspectives, etc. about the tasks you do with those files how do you do them.

may be if you want just compare some columns, or some rows, or look for a value, or change values, or whatever, you could write functions, regexp, etc which will make your tasks easier and more confortable to do. acme chording is really great when you get used to it.

or even writting an acme client :), having a programmable environment gives you many options, original programmes could not imagine all the situations, but they were (and are) smart and included tools making you able to set the program to your needs.

good luck :)
