Documentation

Overview

Package gspath implements file index and search for folders.

It searches file internally with high performance in order by the directory adding sequence. Note that: If caching feature enabled, there would be a searching delay after adding/deleting files.

Functions

func Search

func Search(root string, name string, indexFiles ...string) (filePath string, isDir bool)

Search searches file `name` under path `root`. The parameter `root` should be an absolute path. It will not automatically convert `root` to absolute path for performance reason. The optional parameter `indexFiles` specifies the searching index files when the result is a directory. For example, if the result `filePath` is a directory, and `indexFiles` is [index.html, main.html], it will also search [index.html, main.html] under `filePath`. It returns the absolute file path if any of them found, or else it returns `filePath`.

func SearchWithCache

func SearchWithCache(root string, name string, indexFiles ...string) (filePath string, isDir bool)

SearchWithCache searches file `name` under path `root` with cache feature enabled. The parameter `root` should be an absolute path. It will not automatically convert `root` to absolute path for performance reason. The optional parameter `indexFiles` specifies the searching index files when the result is a directory. For example, if the result `filePath` is a directory, and `indexFiles` is [index.html, main.html], it will also search [index.html, main.html] under `filePath`. It returns the absolute file path if any of them found, or else it returns `filePath`.

Types

type SPath

type SPath struct {
	// contains filtered or unexported fields
}

SPath manages the path searching feature.

func Get

func Get(root string, cache bool) *SPath

Get creates and returns an instance of searching manager for given path. The parameter `cache` specifies whether using cache feature for this manager. If cache feature is enabled, it asynchronously and recursively scans the path and updates all sub files/folders to the cache using package gfsnotify.

func New

func New(path string, cache bool) *SPath

New creates and returns a new path searching manager.

func (*SPath) Add

func (sp *SPath) Add(path string) (realPath string, err error)

Add adds more searching directory to the manager. The manager will search file in added order.

func (*SPath) AllPaths

func (sp *SPath) AllPaths() []string

AllPaths returns all paths cached in the manager.

func (*SPath) Paths

func (sp *SPath) Paths() []string

Paths returns all searching directories.

func (*SPath) Remove

func (sp *SPath) Remove(path string)

Remove deletes the `path` from cache files of the manager. The parameter `path` can be either an absolute path or just a relative file name.

func (*SPath) Search

func (sp *SPath) Search(name string, indexFiles ...string) (filePath string, isDir bool)

Search searches file `name` in the manager. The optional parameter `indexFiles` specifies the searching index files when the result is a directory. For example, if the result `filePath` is a directory, and `indexFiles` is [index.html, main.html], it will also search [index.html, main.html] under `filePath`. It returns the absolute file path if any of them found, or else it returns `filePath`.

func (*SPath) Set

func (sp *SPath) Set(path string) (realPath string, err error)

Set deletes all other searching directories and sets the searching directory for this manager.

func (*SPath) Size

func (sp *SPath) Size() int

Size returns the count of the searching directories.

type SPathCacheItem

type SPathCacheItem struct {
	// contains filtered or unexported fields
}

SPathCacheItem is a cache item for searching.
