For any sizeable project, Go compilation time is just soooo long. Sometimes a build can take upwards of 10 seconds! But you can cut that time down.
This is a plugin for GPM
that runs a go build on all of your
dependencies in the $GOPATH. If you are using a per-project $GOPATH
(the standard way of using GVP) then
prebuilding is a simple way of
improving performance.
Run make install. This will hopefully be in the GPM plugin homebrew
repository soon, too.
Typically this is run right after a gpm install
$ cd my_go_project
$ source gvp in
$ gpm install
$ gpm prebuild
# And edit away!If you also use gpm-git, you
can prebuild those dependencies with gpm prebuild git.
If at any point you need to get rid of those pesky .a files, just do a
gpm prebuild clean.
While Go really does build very quickly, there are practical cases where increasing compilation speed is desireable.
Here's what prompted me to write this plugin: I use vim with syntax
checking. My syntax checker runs each time I write (:w, etc) the file.
And I save often. On a sizeable project, I had to wait several seconds
between when I hit :w and when my editor became active again.
The cause of this is that a few of my dependency libraries are very, very large, and were being re-compiled from scratch with each document save.
The solution: Prebuild the packages. This cut my go build time down to
the point where I don't notice any lag.
