How do I install go.tools/present?

[Ralf Rottmann]

Hi Everybody,

I'm having a hard time getting the present to run on Mac OS X. I have a fully working go environment set up and it's working fine for a larger app engine project. I've copied the output from go env below.

Here's how I try to install present:

go get code.google.com/p/go.tools/present

No output which usually means, everything is fine. However, in $GOPATH/bin there is no present binary. Running go build inside the $GOPATH/src/code.google.com/p/go.tools/present folder yields no output. Same for go install.

Any ideas?

Here's go env:

GOARCH="amd64"

GOBIN=""

GOCHAR="6"

GOEXE=""

GOHOSTARCH="amd64"

GOHOSTOS="darwin"

GOOS="darwin"

GOPATH="/Users/RalfR/gocode"

GORACE=""

GOROOT="/usr/local/go"

GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"

TERM="dumb"

CC="clang"

GOGCCFLAGS="-g -O2 -fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fno-common"

CXX="clang++"

CGO_ENABLED="1"

go get code.google.com/p/go.talks/present

go install code.google.com/p/go.talks/present

Thanks. Worked like a charm! Didn't understand that go.tools/present is different from go.talks/present. Now, do you happen to have a single sample slide with run-able code embedded? Prepping a lightning talk and really would love to use this! Thanks in advance.

Plenty of examples in https://code.google.com/p/go/source/browse/?repo=talks#hg%2F2013

Great and got it working. One last question: In the slides from go.talks there is:

.play concurrency/support/boring.go /START/,/STOP.*/

or

.play concurrency/support/lessboring.go /START/,/STOP/

or

.play concurrency/support/lessboring.go /^func.main/,$

I understand that .play makes the code run-able in the browser, but what's the /START/,/STOP.*/ part?

The go code has the corresponding comments and only the stuff between the comments will be shown. It allows to show part of the file at a time, or just ignore the unimportant bits...

Just stumbled upon the Plan9 reference and that makes things clear. Now heading back to Go on Managed VMs on App Engine... have to say, a great, fantastic language so far. We're using it at grandcentrix to build a real-world backend which will serve potentially millions of Germans during a major TV event in May.

And: Added you on Google+ because you keep jumpin' in even on my pretty basic questions here. Thanks, great community is half of what it needs to fall in love with a language for me.
