README

tegola's built in viewer code is stored in the static/ directory. To generate a bindata file so the static assets can be compiled into the binary, bindata-assetfs is used. Once bindata-assetfs is installed the following command can be used to generate the file for inclusion:

go-bindata-assetfs -pkg=server -ignore=.DS_Store static/...

bindata-assetfs also supports a debug mode which is descriped as "Do not embed the assets, but provide the embedding API. Contents will still be loaded from disk." This mode is ideal for development and can be configured using the following command:

go-bindata-assetfs -debug -pkg=server -ignore=.DS_Store static/...

Functions

func Asset added in v0.4.0 

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDir added in v0.4.0 

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy: 

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.

func AssetInfo added in v0.4.0 

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames added in v0.4.0 

func AssetNames() []string

AssetNames returns the names of the assets.

func MustAsset added in v0.4.0 

func MustAsset(name string) []byte

MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.

func RestoreAsset added in v0.4.0 

func RestoreAsset(dir, name string) error

RestoreAsset restores an asset under the given directory

func RestoreAssets added in v0.4.0 

func RestoreAssets(dir, name string) error

RestoreAssets restores an asset under the given directory recursively

func Start 

func Start(port string)

Start starts the tile server binding to the provided port

func TileCacheHandler added in v0.4.0 

func TileCacheHandler(next http.Handler) http.Handler

TileCacheHandler implements a request cache for tiles on requests when the URLs have a /:z/:x/:y scheme suffix (i.e. /osm/1/3/4.pbf)
