Functions ¶
func Add ¶
Add unpacks and adds the `content` into the default resource object. The unnecessary parameter `prefix` indicates the prefix for each file storing into current resource object.
func GetContent ¶
GetContent directly returns the content of `path` in default resource object.
func IsEmpty ¶
func IsEmpty() bool
IsEmpty checks and returns whether the resource manager is empty.
func Load ¶
Load loads, unpacks and adds the data from `path` into the default resource object. The unnecessary parameter `prefix` indicates the prefix for each file storing into current resource object.
func Pack ¶
Pack packs the path specified by `srcPaths` into bytes. The unnecessary parameter `keyPrefix` indicates the prefix for each file packed into the result bytes.
Note that parameter `srcPaths` supports multiple paths join with ','.
func PackToFile ¶
PackToFile packs the path specified by `srcPaths` to target file `dstPath`. The unnecessary parameter `keyPrefix` indicates the prefix for each file packed into the result bytes.
Note that parameter `srcPaths` supports multiple paths join with ','.
func PackToGoFile ¶
PackToGoFile packs the path specified by `srcPaths` to target go file `goFilePath` with given package name `pkgName`.
The unnecessary parameter `keyPrefix` indicates the prefix for each file packed into the result bytes.
Note that parameter `srcPaths` supports multiple paths join with ','.
Types ¶
type File ¶
type File struct {
// contains filtered or unexported fields
}
func GetWithIndex ¶
GetWithIndex searches file with `path`, if the file is directory it then does index files searching under this directory.
GetWithIndex is usually used for http static file service.
func ScanDir ¶
ScanDir returns the files under the given path, the parameter `path` should be a folder type.
The pattern parameter `pattern` supports multiple file name patterns, using the ',' symbol to separate multiple patterns.
It scans directory recursively if given parameter `recursive` is true.
func ScanDirFile ¶
ScanDirFile returns all sub-files with absolute paths of given `path`, It scans directory recursively if given parameter `recursive` is true.
Note that it returns only files, exclusive of directories.
func UnpackContent ¶
UnpackContent unpacks the content to []*File.
func (*File) MarshalJSON ¶
MarshalJSON implements the interface MarshalJSON for json.Marshal.
func (*File) Open ¶
func (f *File) Open() (io.ReadCloser, error)
Open returns a ReadCloser that provides access to the File's contents. Multiple files may be read concurrently.
type Resource ¶
type Resource struct {
// contains filtered or unexported fields
}
func Instance ¶
Instance returns an instance of Resource. The parameter `name` is the name for the instance.
func (*Resource) Add ¶
Add unpacks and adds the `content` into current resource object. The unnecessary parameter `prefix` indicates the prefix for each file storing into current resource object.
func (*Resource) GetContent ¶
GetContent directly returns the content of `path`.
func (*Resource) GetWithIndex ¶
GetWithIndex searches file with `path`, if the file is directory it then does index files searching under this directory.
GetWithIndex is usually used for http static file service.
func (*Resource) Load ¶
Load loads, unpacks and adds the data from `path` into current resource object. The unnecessary parameter `prefix` indicates the prefix for each file storing into current resource object.
func (*Resource) ScanDir ¶
ScanDir returns the files under the given path, the parameter `path` should be a folder type.
The pattern parameter `pattern` supports multiple file name patterns, using the ',' symbol to separate multiple patterns.
It scans directory recursively if given parameter `recursive` is true.
Note that the returned files does not contain given parameter `path`.
func (*Resource) ScanDirFile ¶
ScanDirFile returns all sub-files with absolute paths of given `path`, It scans directory recursively if given parameter `recursive` is true.
Note that it returns only files, exclusive of directories.
