go's Issues

cmd/acme: cannot Kill running commands

To reproduce, middle click on sleep 1000.
Then middle click on Kill sleep.
The sleep process remains intact.

acme/Watch: dial unix /tmp/ns..:0/acme: not supported by plan 9

I was hoping to get acme commands to run on native Plan 9 edition 4.

Unfortunately, neither acme/Watch nor acme/acmego wasn't able to run. I assume that's because they rely on UDS that is provided by plan9port's version of acme, which is not the case on Plan 9 (?).

I'll be glad to implement the fix, but I'm not fluent enough with Plan 9/acme architectures yet. If you could give me a hint, I could give it a try. In either case, I can test somebodies PR.

how-to <build> in readme

Newbie to both Plan9 and Golang here. Please excuse using Issues as a communication channel - will happily use another if provided.
Trying to build the packages, but makefile returns:

:~/workspace/9fans/go.git/acme$ make
Makefile:1: /usr/local/go/src/Make.inc: No such file or directory
Makefile:7: /usr/local/go/src/Make.pkg: No such file or directory
make: *** No rule to make target '/usr/local/go/src/Make.pkg'.  Stop.

my GOROOT is pointing to the Golang deployment as below:

~/workspace/9fans/go.git/acme$ $GOROOT/bin/go version
go version go1.15.2 linux/amd64

It would be great if README contained a section on build steps.

install error on mac

go install 9fans.net/go/...@latest failed on my Macbook, v12.6.1.

I'm running go version go1.19.3 darwin/arm64

I tried cleaning the module cache but it didn't seem to help. go complains:

../../pkg/mod/9fans.net/[email protected]/cmd/samterm/unix.go:62:21: cannot use fd (variable of type int) as type *os.File in argument to extproc

I'm not very familiar with go so sorry if this an easy fix. The install seemed to work perfectly fine on my Linux box.

plan9/fcall: set Count when unmarshalling Rread

308     case Rread:
309         n, b = gbit32(b)
310         if len(b) != int(n) {

312         }
313         f.Data = b

After 313, add the line

            f.Count = uint32(len(b))

cmd/acme: more deadlocks

Making a new issue for deadlocks found after the recent fixes.

I've also instrumented my version to report which goroutine id held the deadlock and where it was acquired.

4s hangs on Windows

When I try to execute 4s on Windows with devdraw from http://sam.cat-v.org/_files/win32_sam.zip, it hangs and uses up all memory, never creating a new window.

Steps to reproduce:

Have devdraw.exe in your PATH.
go get 9fans.net/go/games/4s
%GOPATH%/bin/4s

acmego doesn't seem to do anything

Expected behavior:

Run acmego
Change a go file, using improper indentation
Put the file
Buffer is modified with go fmt'd contents

Apologies if I'm missing something simple, but it's just not working for me. I have a recently-updated p9p install on Debian.

^D

acmego - check for existing instances

acmego doesn't report exisiting acmego instances, which can cause weird behaviour (gofmt text doubling). Maybe there should be a lock file? Or just a pidof-like check?

cmd/acme: autoscrolling doesn't work correctly

To reproduce: start selecting, drag mouse off the bottom of the window keeping mouse button held down. The selection does not continue to grow.

cmd/acme: Dump creates corrupted acme.dump files

I'm aware that cmd/acme isn't under active maintenance, but filing this here anyway,
because I've just started to use it in earnest after one too many memory corruption issue
with the original acme and it seems like a reasonable place to record issues.

Here's a portion of a corrupted dump file, created by middle-clicking on Dump:

This causes acme to panic on Load because there's a header line with no | character.

cmd/acme: window directories missing from fs

If I run 9p ls acme, I see something like this:

----------- M 0 rogpeppe rogpeppe 0 Nov  4 07:29 ''
d-r-x------ M 0 rogpeppe rogpeppe 0 Nov  4 07:29 acme
--rw------- M 0 rogpeppe rogpeppe 0 Nov  4 07:29 cons
----------- M 0 rogpeppe rogpeppe 0 Nov  4 07:29 consctl
d---------- M 0 rogpeppe rogpeppe 0 Nov  4 07:29 draw
---w------- M 0 rogpeppe rogpeppe 0 Nov  4 07:29 editout
--r-------- M 0 rogpeppe rogpeppe 0 Nov  4 07:29 index
--rw------- M 0 rogpeppe rogpeppe 0 Nov  4 07:29 label
--r-------- M 0 rogpeppe rogpeppe 0 Nov  4 07:29 log
d-r-x------ M 0 rogpeppe rogpeppe 0 Nov  4 07:29 new

None of the window directories are present (although they can be walked to) and there's that odd empty-named file with no permissions.

Adding persian/arabic language support

Hi, I wanted to know now that acme is being implemented in Go, can we add support for persian/arabic language to it ?

go/draw does not work on native plan9 system.

Note: I was running the latest version of 9front in virtualbox.

I was rewriting a small graphics example I found in C that used libdraw to make a bouncing ball in Go using go/draw. Somehow I missed the first line on the pkg.go.dev which states that the package connects to devdraw from plan9port. This essentially means that go/draw doesn't work on plain plan9 OS or a fork of it?

Is there any plans to add support for native plan9 or does someone know of an equivalent beyond using cgo?

Win.Seek("body", 0, io.SeekEnd) always returns 0

Win.Seek always returns 0 in case of io.SeekEnd, io.SeekCurrent. Does it understand them correctly?

Is there any other way to get the size of window data in bytes?

I wrote a simple tool for acme that runs guru on selected entity. It can run different guru commands for three selection kinds: pointing at, select, select before.

The problem is that guru requires byte offsets but Win.ReadAddr returns character offsets (maybe it is guru bug).

I've managed to obtain the required byte offsets of selection but it is based on hack that requires read data from current selection to the end of file and next read the whole body.

Somethat similar to the fixed problem in #53.

cmd/acme: command run in background stays in row tag

To reproduce, middle-click on sleep 1 & in a window tag.
The sleep appears in the row tag but never goes away.

9fans.net has disappeared into thin air

As per issue #3, I have been trying to install godef and running up against the problem indicated in their issue (rogpeppe/godef#4) in addition to the issue above. The last comment in #3 says that the server is back in The Cloud but that it might disappear into thin air. So I am raising this issue to highlight that it has indeed disappeared into thin air. Might it be prudent to point the 9fans.net package name to github.com/9fans instead?

TL/DR, suggested fix: change 9fans.net/go/* to github.com/9fans/go/*

9fans.net is down

I can't install godef since godef requires acme and 9fans.net is down.

package acme // import "9fans.net/go/acme"

9pserve: announce unix!/tmp/ns.hherman.:0/acme: No such file or directory

I'm trying to work out why this is happening, but in the mean time I thought you might also like to know about it. I've deleted a few of the plan9 binaries from my machine that were colliding with programs I use normally (e.g zip or tar), so possibly I've deleted something important. If this rings any bells, pointers would be much appreciated!

test issue

sam: no output from ! command

$ sam -d

acme: regex not mathing as much as possible

Considering the following text:

abc xyz

The following Edit command:

Edit ,x/[a-z]+/ s/.*/T&/g

Should result in

Tabc Txyz

But it seems like x is capturing single chars only, instead the full 3 char group, so the command results in :

TaTbTc TxTyTz

I tried to find the problem to fix it myself but could not find where the bug is. It seems to work fine in go sam and plan9port acme.
