I am using dep to manage the dependencies of a Go tool I'm writing.
This tool uses https://github.com/desertbit/grumble as an dependency. This in turn uses https://github.com/chzyer/readline as a dependency. The problem is that when trying to run my tool I get the following error:
vendor/github.com/desertbit/grumble/app.go:295:20: unknown field 'HistorySearchFold' in struct literal of type readline.Config
I know why this is happending. grumble uses the master branch of readline as a dependency. In this the field
HistorySearchFold is available.
dep ensure not the master but the 1.4 tag is pulled into the vendor folder.
My question therefore is: How can I force dep to pull the master branch instead?
I tried adding the following in my Gopkg.toml file:
[[constraint]] branch = "master" name = "github.com/chzyer/readline"
Sadly this is not working. When I check the version pulled into the vendor folder it is still 1.4.
