Watcher crashes when using a different root in config about fresh

[gravityblast]

hi @justinfx, can you please post your config file?

[justinfx]

It's the default sample config, with just the root value changed:

root:              domain.com/me/myProject/src
tmp_path:          ./tmp
build_name:        runner-build
build_log:         runner-build-errors.log
valid_ext:         .go, .tpl, .tmpl, .html
build_delay:       600
colors:            1
log_color_main:    cyan
log_color_build:   yellow
log_color_runner:  green
log_color_watcher: magenta
log_color_app:

@justinfx if you are running fresh from the myProject folder, can you try setting ./src as root?

Hi, sorry it took me so long to reply on this issue.
Yes, changing to ./src as the root does allow fresh to run, but it is only monitoring that src directory as the root, which means you must have go files in the root of your project for it to monitor anything.

I realize that fresh has to know where to issue a build in terms of the source, but it might be nice to be able to express the src root separately from the monitor root. Something like:

1. Keep root the way it is, acting as both the src root and monitor root
2. But, if the config specifies src_root, then use that for building the source, and root for watching changes

And it would also be nice if the paths could use [os.ExpandEnv|http://godoc.org/os#ExpandEnv] so that you can use $GOPATH in your path:

root          $GOPATH/domain/project
src_root    $GOPATH/domain/project/src

This would allow all of the files in the project tree to be monitored, as well as supporting the actual go source files be in a subdirectory. It would probably help support other projects that are multi-language.

Also, in terms of my originally posted issue... fresh does completely panic if you specify a bad path as a root. It might be nice if it legitimately checked the path and died gracefully with "Path does not exist" instead of a "invalid memory address or nil pointer dereference"
