extender
Go toolchain subcommand extender.
See gomatic/extenders for a list of known extenders.
for critics
Here's a quick explanation for the shortsighted who just love to criticize before they take the two seconds needed to grasp the actual purpose of such a tool:
- This isn't about typing
go vend
instead ofgovend
. - This is about being able to replace or augment native
go
toolchain commands. e.g.- Do you have specific things you need as part of
go build
, e.g. adding common-X
? Then just install the augmentations and you've changed the behavior ofgo build
. - Don't like how
go dep
,go vet
,go *
works? Replace it with a different implementation.
- Do you have specific things you need as part of
It allows Go developers to continue using the standard toolchain and simple commands but gain different/customized functionality ... because, thankfully, we don't all like exactly the same things, so flexibility is useful.
If you're concerned about complexity and fragmentation ... then i'll challenge you to create a simple toolchain that does everything everyone needs in every situation. When someone has done that, I'll delete this repository.
introduction
extender
provides a go
executable to precede GOROOT/bin/go
.
This allows you to extend the go
toolchain or even replace Go's native subcommands.
extender
's go
executable provides the ability to call subcommands through
the go
command. The subcommands are implemented as executables with a recognizable
prefix (default is go-
and go
) instead of natively by GOROOT/bin/go
(and the
GOTOOLDIR
tools). If such an executable doesn't exist, it falls back to
GOROOT/bin/go
.
For example,
go ex
will (by default) execute
go-ex
or, if that doesn't exist, it tries
goex
A consequence: allows pointing the go command to separate versions of go
.
GOROOT=/go1.8.1 go build
GOROOT=/go1.7.5 go build
Installation
go
executable to your GOBIN
or
GOPATH[0]/bin
and overrides GOROOT/bin
in the PATH
go get github.com/gomatic/extender/...
eval $(extender)
Additional, you can specify the prefixes that'll be considered extensions (the default is go- go
):
eval $(extender go go-)
will first look for, e.g., goex
and if not found, go-ex
, then try GOROOT/bin/go ex
.
