What is globule?
The globule npm package is a utility for file system operations that involve matching file paths using glob patterns. It provides a simple and flexible way to find, read, and manipulate files based on patterns.
What are globule's main functionalities?
File Matching
This feature allows you to find files that match a specific glob pattern. In this example, it finds all JavaScript files in the 'src' directory and its subdirectories.
const globule = require('globule');
const matches = globule.find('src/**/*.js');
console.log(matches);
File Copying
This feature allows you to copy files that match a specific glob pattern to a new location. In this example, it copies all JavaScript files from the 'src' directory to the 'dist' directory.
const globule = require('globule');
globule.copy('src/**/*.js', 'dist');
File Deletion
This feature allows you to delete files that match a specific glob pattern. In this example, it deletes all JavaScript files in the 'dist' directory and its subdirectories.
const globule = require('globule');
globule.del('dist/**/*.js');
File Reading
This feature allows you to read the contents of files that match a specific glob pattern. In this example, it reads and logs the contents of all JavaScript files in the 'src' directory and its subdirectories.
const globule = require('globule');
const files = globule.find('src/**/*.js');
files.forEach(file => {
const content = globule.read(file);
console.log(content);
});
Other packages similar to globule
glob
The 'glob' package is a popular library for matching files using glob patterns. It is similar to 'globule' but focuses solely on file matching without additional file manipulation features. It is widely used and has a simple API for finding files.
fast-glob
The 'fast-glob' package is a high-performance alternative to 'glob' and 'globule'. It offers faster file matching and supports advanced features like concurrency and caching. It is suitable for large projects where performance is critical.
minimatch
The 'minimatch' package is a lightweight library for matching file paths against glob patterns. It is often used as a dependency in other packages and provides a simple and efficient way to perform pattern matching.
globule
An easy-to-use wildcard globbing library.
Getting Started
Install the module with: npm install globule
var globule = require('globule');
var filepaths = globule.find('**/*.js');
Documentation
globule.find
Returns a unique array of all file or directory paths that match the given globbing pattern(s). This method accepts either comma separated globbing patterns or an array of globbing patterns. Paths matching patterns that begin with !
will be excluded from the returned array. Patterns are processed in order, so inclusion and exclusion order is significant. Patterns may be specified as function arguments or as a src
property of the options object.
globule.find(patterns [, patterns [, ...]] [, options])
globule.find({src: patterns, })
The options
object supports all glob library options, along with a few extras. These are the most commonly used:
src
This property may be used instead of specifying patterns as function arguments.filter
Either a valid fs.Stats method name or a function that will be passed the matched src
filepath and options
object as arguments. This function should return a Boolean
value.nonull
Retain globbing patterns in result set even if they fail to match files.matchBase
Patterns without slashes will match just the basename part. Eg. this makes *.js
work like **/*.js
.srcBase
Patterns will be matched relative to the specified path instead of the current working directory. This is a synonym for cwd
.prefixBase
Any specified srcBase
will be prefixed to all returned filepaths.
globule.match
Match one or more globbing patterns against one or more file paths. Returns a uniqued array of all file paths that match any of the specified globbing patterns. Both the patterns
and filepaths
arguments can be a single string or array of strings. Paths matching patterns that begin with !
will be excluded from the returned array. Patterns are processed in order, so inclusion and exclusion order is significant.
globule.match(patterns, filepaths [, options])
globule.isMatch
This method contains the same signature and logic as the globule.match
method, but returns true
if any files were matched, otherwise false
.
globule.isMatch(patterns, filepaths [, options])
globule.mapping
Given a set of source file paths, returns an array of src-dest file mapping objects. Both src and dest paths may be renamed, depending on the options specified. Patterns may be specified as function arguments or as a src
property of the options object.
globule.mapping(filepaths [, filepaths [, ...]] [, options])
globule.mapping({src: filepaths, })
In addition to the options the globule.find
method supports, the options object also supports these properties:
srcBase
The directory from which patterns are matched. Any string specified as srcBase
is effectively stripped from the beginning of all matched paths.destBase
The specified path is prefixed to all dest
filepaths.ext
Remove anything after (and including) the first .
in the destination path, then append this value.extDot
Change the behavior of ext
, "first"
and "last"
will remove anything after the first or last .
in the destination filename, respectively. Defaults to "first"
.flatten
Remove the path component from all matched src files. The src file path is still joined to the specified destBase.rename
If specified, this function will be responsible for returning the final dest
filepath. By default, it flattens paths (if specified), changes extensions (if specified) and joins the matched path to the destBase
.
globule.findMapping
This method is a convenience wrapper around the globule.find
and globule.mapping
methods.
globule.findMapping(patterns [, options])
Examples
Given the files foo/a.js
and foo/b.js
:
srcBase and destBase
globule.find("foo/*.js")
globule.find("*.js", {srcBase: "foo"})
globule.find({src: "*.js", srcBase: "foo", prefixBase: true})
globule.findMapping("foo/*.js")
globule.findMapping("foo/*.js", {destBase: "bar"})
globule.findMapping({src: "*.js", srcBase: "foo", destBase: "bar"})
globule.mapping(["foo/a.js", "foo/b.js"])
globule.mapping(["foo/a.js", "foo/b.js"], {destBase: "bar"})
globule.mapping("foo/a.js", "foo/b.js", {destBase: "bar"})
globule.mapping(["a.js", "b.js"], {srcBase: "foo", destBase: "bar"})
globule.mapping({src: ["a.js", "b.js"], srcBase: "foo", destBase: "bar"})
