go1.5 download path

#23

local gobrew version file name (version -> gobrew_version)

Sometimes, if I used the version file name in my project, it caused some confusion about gobrew. Version is too normal of a file name, so I changed the file name to gobrew_version.

The go downloads now include the Mac OS X version in the filename, they didn't before so the gobrew-install script needs to be fixed.

The new file name looks like: go1.2.darwin-amd64-osx10.8.tar.gz instead of go1.2.darwin-amd64.tar.gz

I think name not contains osx10.8 now.

gobrew install 1.4

return ok;

gobrew use 1.4

return ok;

gobrew version

return 1.4

BUT

go version

return 1.6, not ok, because i want it to be 1.4

did i miss something here?

Created easy to use install / upgrade / uninstall scripts, mentioned by #5

Install is now just one command. Like:

curl -L https://raw.github.com/grobins2/gobrew/master/tools/install.sh | sh

GitHub changed the way Markdown headings are parsed, so this change fixes it.

ls command output vary from OS to OS. In my case, awk '{print $9}' shows time of last modification. Since the last field always shows directory name, we have to get it by $NF to get dir names of go versions.

$ ls -l
total 0
drwxr-xr-x  20 abc123  Hoge Users  680  3 29 15:23 1.8

If some directory has  "version" directory, go command in `gobrew` does not works.

$ls
CONTRIBUTING.md  LICENSE     api        flags.go  join_test.go  manage.go  state

$go
cat: /home/anarch/go/swarm/src/github.com/docker/swarm/version: Is a directory
gobrew: couldn't find any version specified for use

by not including "go.googlecode.com" in the grep regex, it'll make it easier for gobrew_fw to host the files while to still enabling gobrew list to work.

sourcing the profile causes the gobrew-init script to run which sets up directories and other stuff which is required to install go. (ex: $HOME/.gobrew/cache gets created)

I'm just setting up a new OSX machine with the M1 chip. I did my go brew installation with the curl command and installed go 1.17. After that I ran gobrew use 1.17. If I run a go command I get zsh: command not found: go

Could it be that gobrew is installing amd64 instead of arm64?

Hello.

Using your install script, it works wrong to install. In the end of script, there is source command to set new profile. As I know, source command is supported only in bash and zsh. I think the script must be executed with bash. Or it is good way that source command is removed and note developers to manually execute it.

When I run gobrew use 1.8 it shows that the version is not installed.

I investigated why and I see this line in libexec/gobrew-use file:

VERSIONS=ls -l $GOBREW_ROOT/versions | egrep '^d' | awk '{print $9}'

and the problem is in awk command because if my user group contains two words and space in between (my user in an Active Directory user) then the version name is on 10th position.

I just fixed it to awk '{print $10}' and it works perfect for me, but maybe you could find some general solution for that case.

Thanks :)

When running gobrew init, the CLI adds a few paths to the PATH environment variable. Unfortunately it adds them in the beginning, not at the end.

This is bad in terms of performance because every call to a binary will then first search these paths, before looking at regular paths such as /usr/local/bin (and I guess that system binaries are more often called than the ones in the directories added by gobrew).

Furthermore this leads to the situation where binaries in the directories added by gobrew have higher precedence than anything that was installed before.

Could this be changed to adding the directories in the end instead of at the beginning?

Whenever I build a gb project, I have to set GOROOT in order for it to find the compiler.

Sourcing the output from go env takes care of this. It'd be nice if gobrew did this automatically when switching versions.
