Embed static content to binary

[at15]

Decided to use rice for embedding assets

• test api 39a59bc
• test cli tools
• test if assets used in TEST are also included. A:NO
• How box with same name in different package are dealt with rice append when rice.MustFindBox is in package GeertJohan/go.rice#4 says it can not deal with multiple packages
• using zip got error on windows Append shows zip exit status 3 on windows, but binary works as expected GeertJohan/go.rice#64 and rice append when rice.MustFindBox is in package GeertJohan/go.rice#4 Using my own fork now
• is relative path to parent folders like ../templates/generator supported
• Support .riceignore

-- old content --
This issue is split from #15. Static content is needed for both web interface and generator.

There are two choices

• https://github.com/jteeuwen/go-bindata
• https://github.com/GeertJohan/go.rice

go-bindata

• https://github.com/gocraft/work/tree/master/webui/internal/assets is a pretty good example for using go-bindata
• https://github.com/elazarl/go-bindata-assetfs let it support http serve

rice

• https://github.com/GeertJohan/go.rice (it has built in support for http.FileSystem)

I think rice has a cleaner api

Test files are not build by go, thus call for FindBox in *_test.go won't be found by rice cli

go build -o Ayi
rice append -i github.com/dyweb/Ayi/util/embed --exec Ayi
no calls to rice.FindBox() or rice.MustFindBox() found in import path `github.com/dyweb/Ayi/util/embed`
Error setting zip offset: exit status 13

But how to add multiple import paths?

For the zip problem

• run zip -A Ayi get

$ zip -A Ayi
        zip warning: central dir not where expected - could not adjust offsets
        zip warning: (try -FF)

zip error: Zip file structure invalid (Ayi)

From GeertJohan/go.rice#4

You can currently do this by using rice --import-path append --exec alpaca.exe. But that will only allow you to append/embed one package.

Doing a recursive find in all imported packages is something I thought about before.. Simply finding boxes recursively in packages probably won't work since rice allows relative paths, and so you might get multiple different folders with the same name (e.g. templates folder in different packages). It'll probably require some breaking changes in the way a package is appended/embedded and loaded during execution. Maybe need to append with full (absolute) path's to avoid duplicates.
I hope the rice with --import-path will solve your problem. I'll add 'finding boxes in imported packages' to the TODO list.

but multiple packages is supported, by calling -i multiple times? and I need to rename the boxes with prefixes, like app-web-assets, app-generator-assets

I disabled zip -A and is currently using my own fork https://github.com/at15/go.rice , though it's better to detect OS, but I don't have test environment, so just make sure windows is working.

use gommon/noodle, which support .noodleignore dyweb/gommon#47
