[9fans] first timer - editing plan9.ini

[9fans] first timer - editing plan9.ini

[Corey]

Ok, so I have my fossil+venti and hopefully soon-to-be cpu and auth-server
booted up for the first time, and I'm in rio as user glenda.

I'm continuing to follow the docs, which is prompting me to edit plan9.ini for
various things.

sam is completely opaque to the uninitiated. (I'm a mere vi fanatic)

Before I go into sitting down and learning sam, it would be nice to simply be
able get the machine running in a minimally satisfactory way, i.e.: network
online, display running at reasonable depth, venti finished, and auth-serv
working.

Can someone give me just the bare minimal sam command/info that I need to:

edit a couple lines
close and save properly


... better yet: is there a simple/minimal editor that doesn't require
learning a command language to begin using it first?

I began by beginning to read through sam_tut.pdf, and I look forward to
gaining proficiency with it... but not at this moment - I just want to get my
new plan9 box running so I can access it remotely.

As it is, I'm guessing I'm just going to hose my plan9.ini if I try editing it
before I'm well familiar with sam...


THanks!

You can use acme if you want. Otherwise:

% 9fat:
% sam /n/9fat/plan9.ini
right click and select the filename, then midclick in the white area
of the sam window. This should bring up the file.
Make your changes, then click in the light blue part of the sam
window. Type 'w' and hit enter, then type 'q' and hit enter. This
should write and quit.

You can basically treat sam like ed with windows, but there are more
complex commands available too.

Myself, I usually use acme.

That was my first effort (though it suffered similar issue: must acclimate to
acme before you can configure your new installation) - however, when I
tried to traverse /n/9fat/plan9.ini, acme complained that there was no
such file; so, being completely new to plan 9, my progress at that point
came to a complete standstill.

Thanks - I'll try this.


Another quick question:

Just to be safe, I would like to copy the org plan9.ini before I try to modify
it; so if I hose it, I can move it back; how would I do this?

Run 9fat: first, then run acme in the same window. Or, run acme, then
do the command "Local 9fat:" inside the editor.

You need to learn about namespaces. And the task you're setting out to
perform is not a difficult one, especially considering that a terminal
boots with Acme already showing the readme file--so READ ME. The
"Local" trick may be the only part that's not obvious.

in rio, i prefer to plumb the string "Local 9fat:".  this
means that all new windows will inherit /n/9fat in their
namespaces.

Yep, I like to read readme's.  In fact I read that particular one several
times before querying 9fans.

Anyhow, I'm back on track - thanks for the assist, guys.

cp plan9.ini plan9.ini.old

acme didn't see /n/9fat/plan9.ini because the 9fat partition wasn't
mounted in its namespace.

The few minutes spent learning ed(1) will be well repaid. You'll be
one of the smartest guys on your block.

Yes, however I simply want to put off that learning, from: _right_this_moment_,
to: _after_my_box_is_online_.

i second that.  learning it has been one of the best investments of my
time since 1982.

I would say the same thing about vi, which I practically live in, and feel
hamstrung without.

At anyrate, I do intend on sitting down and becoming at least comfortable
with sam's ed.

Though I'm guessing that I'll be installing Stefan's vim port asap - I'm
_extremely_ happy that this exists.

It's sad to see people recommending acme instead of helping a bit with
Sam. You should try both, and use what fits you. I like Sam because it
is just an editor. Acme is more of a platform for making tools
interact, and to me ends up feeling like a swiss army chainsaw. I've
left vi behind because I learned Sam, and maybe you'll like it enough
to switch, too.

Until you get proficient in Sam, using the right-button menu will give
you the file-related commands you need, and / and s in the command
window will do until you learn the more powerful Sam commands and
idioms.

To get more proficient, I highly recommend Rob's paper 'A Tutorial For
The Sam Command Language' and the Sam reference card, which show you
the idioms for using Sam more effectively and give you a glimpse of
it's power. It helps if you read them more than once.

Good luck, I hope you find Sam or Acme to your liking :)

I used 9vim for a little while. It helped a lot during that difficult phase of having to edit lots of files while still being unused to the system. I don't bother with it any more, it was just useful in ameliorating the precipitousness of the learning curve during the first few weeks.

Also ed "scripts" can be quite handy to have around indeed.

The advantage of Acme is that there isn't much learning: all the commands
are obvious (eg Put writes back to disk), but you do have to learn the mouse
clicks to execute them.

I use sed's language constantly, and look forward to expanding my bag of
tricks with sam.  Stream editors are without-a-doubt the most useful tool I
have for editing files, because I can write scripts that edit them for me.

I found that sam had a limiting command-line interface, so I wrote a script
around it (ssam) that gives at a more sed-like stream-editing interface: -e
accepts a (series of) sam commands; -f accepts the name of a file with sam
commands; and you can pipe in the text you want to change, then use -e or -f
to supply the commands.  It puts all the text it changes on standard output.
 It's in code-review right now, so if you use it let me know (-G sends a
gripe with mail) if it doesn't work well for you.

Nope. Learn ed(1). It's really very simple to use.
