[9fans] plan9port's acme - open a file to a desired line number.

[9fans] plan9port's acme - open a file to a desired line number.

[Lluís Batlle]

Hi... I'd like to open a file in acme at line, let's say, 10.

acme file:10  # doesn't work

if I already started acme, I tried this way:

(echo name file; echo get; echo dot=10) | 9p write acme/new/ctl

But it doesn't work - it says the "dot=" command is ill-formed. What I
am doing wrong?

Thanks,
Lluís.

try this:

	; plumb file:10

or use the 9term plumb menu.  you've got to either run awd manually
for this to work or redefine cd to

	fn cd { if(flag i)cd $* && awd }

better yet, run win(1) within acme and use b3 on the file:line combination.

the B command also opens a file in acme from the command prompt:

	 ; B file:10

Thanks, it works fine! I really needed to open a file from a command
(it's for cbrowser's Edit call).

Re: [9fans] plan9port's acme - open a file to a desired line number.

good point.  what was i thinking.

does anyone know the reason that files on the command line are treated differently
than files passed in via the plumber?

The address (10) has to be written to addr and not to ctl file.
To accomplish "B file:10" using acme control files:

	; . $PLAN9/lib/acme.rc
	; newwindow
	; winname /path/to/file
	; winctl get
	; echo -n 10 | winwrite addr
	; winctl 'dot=addr'

note that there is also E. E (and B) are documented in sam(1) :

  B is a shell-level command that causes an instance of sam [or acme]
  running on the same terminal to load the named files. [...]

  E is a shell-level command that can be used as $EDITOR in a
  Unix environment. It runs B on file and then does not exit
  until file is changed, which is taken as a signal that file
  is done being edited.

Thank you!  You've just made acme my perforce check-in editor!

Genius :-)

Re: [9fans] plan9port's acme - open a file to a desired line number.

I don't know how I didn't notice before, but it seems using "B" with
linenumber addressing doesn't work accessing files of a ClearCase view
(that is, a special filesystem in Linux). It opens a filename, as the
filename had the ":linenumber" within. If I right click the title of
the new void window created, it opens a new window with the correct
file, and the cursor at the specified line number.

Does anybody know if that wrong behaviour could be related to acme/B?
Of course I can open those files with gvim or some other editors
without problem - but in acme, not with B.

Ah, if I don't add a line number, the file is correctly opened in any
case (B or right click).

Any clue?

This happens because plumber was started before setting
the dynamic view.  If both plumber and acme are started
after setting the view, "B file:linenumber" will work fine.

True, it works... I forgot about the plumber!

Thank you very much.

To avoid restarting plumber and acme everytime the view
is changed, you may replace calls to cleanname in B
    `cleanname -d "$pwd" "$i"`
with
    `cleanname -d "$pwd" "$i" | sed "s;^/vobs/;$CLEARCASE_ROOT&;"`
(assuming all VOB tags start with /vobs.)

[Lluís Batlle]

Oh that's nice. In fact what I did is changing the namespace for it to
depend on $CLEARCASE_ROOT - it worked, but I had to start a plumber
every time. I'll try your solution.

Thanks!
