Simple git package inspired in nodejs simple-git. This package provide sync and async methods

Plugin   Example

Simple Git #

A lightweight interface for running git commands in any dart application.

Simple git package is inspired in nodejs simple-git #

This package is not be intended to be a exact clone of simple-git(node js), improvements and new features are welcome!

Installation #

Add as dependency in pubspec.yaml

    simple_git: any

System Dependencies #

Requires git to be installed and that it can be called using the command git.

Usage #

Include into your dart app using:

import 'package:simple_git/simple_git.dart';

var simpleGit = SimpleGit(SimpleProcessOptions());

Configuration #

Configure each simple_git instance with a properties object passed to the SimpleGit constructor:

import 'package:simple_git/simple_git.dart';

var options = SimpleProcessOptions();

// or

// All fields are optionals
  var options = SimpleProcessOptions(
    baseDir: Directory.current.path, // working directory for `git` commands to run in
    showOutput: true, // this make all output be printed on terminal (default = false)
    binary: 'git',
    config: 'http.proxy=someproxy',
    maxConcurrentProcesses: 6,
    runInShell: true,

All configuration properties are optional, the default values are shown in the example above.

Per-command Configuration #

To prefix the commands run by simple_git with custom configuration not saved in the git config (ie: using the -c command) supply a config option to the instance builder:

// configure the instance with a custom configuration property
var options = SimpleProcessOptions(
  config: 'http.proxy=someproxy'

// any command executed will be prefixed with this config
// runs: git -c http.proxy=someproxy pull

The default SimpleGit is "sync", but you can use the async version SimpleGitAsync. #

Using task Future #

You can chaining commands using cascade operators on Sync version or run all commands at same time using async. Or await the Future get finished

// Sync
simpleGitSync..init()..addRemote('origin', '...remote.git');

// Async with await
await simpleGitAsync.init();
await simpleGitAsync.addRemote('origin', '...remote.git')

// Async at same time (Future.await is possible also)
simpleGitAsync..init()..addRemote('origin', '...remote.git');

Catching errors GitException #

To catch errors in async code, either wrap the whole chain in a try/catch:

try {
    await simpleGitAsync.init();
    await simpleGitAsync.addRemote(name, repoUrl);
} on GitException catch(gitException) { /* handle all git errors here */ }
catch (e) { /* handle all other kind of errors here */ }

or catch individual steps to permit the main chain to carry on executing rather than jumping to the final catch on the first error:

// Async
    await simpleGitAsync.init().catchError(gitException); // GitException
  // Sync
  // handle the error manually
  var result = simpleGit.init(skipOnError: true); // Not throw error if `skipOnError: true`
  if (result.exitCode != 0) {
    print('Error: ' + result.stderr);
    // return

Using task callbacks HandlerFunction #

  handlerFn: (result) { // ProcessResult result
      // always fired! with error or not

Task Responses ProcessResult #

Whether using a trailing callback, sync or async commands, tasks either return the ProcessResult or Future<ProcessResult> response.

Take a look in the example project folder for more samples. #


APIWhat it does
.add([fileA, ...], handlerFn)adds one or more files to be under source control
.addAnnotatedTag(tagName, tagMessage, handlerFn)adds an annotated tag to the head of the current branch
.addTag(name, handlerFn)adds a lightweight tag to the head of the current branch
.catFile(options[, handlerFn])generate cat-file detail, options should be an array of strings as supported arguments to the cat-file command
.checkIgnore([filepath, ...], handlerFn)checks if filepath excluded by .gitignore rules
.clearQueue()immediately clears the queue of pending tasks (note: any command currently in progress will still call its completion callback)
.commit(message, handlerFn)commits changes in the current working directory with the supplied message where the message can be either a single string or array of strings to be passed as separate arguments (the git command line interface converts these to be separated by double line breaks)
.commit(message, [fileA, ...], options, handlerFn)commits changes on the named files with the supplied message, when supplied, the optional options object can contain any other parameters to pass to the commit command, setting the value of the property to be a string will add name=value to the command string, setting any other type of value will result in just the key from the object being passed (ie: just name), an example of setting the author is below
.customBinary(gitPath)sets the command to use to reference git, allows for using a git binary not available on the path environment variable
.cwd(workingDirectory)Sets the current working directory for all commands after this step in the chain
.diff(options, handlerFn)get the diff of the current repo compared to the last commit with a set of options supplied as a string
.diff(handlerFn)get the diff for all file in the current repo compared to the last commit
.diffSummary(handlerFn)gets a summary of the diff for files in the repo, uses the git diff --stat format to calculate changes. Handler is called with a nullable error object and an instance of the DiffSummary
.diffSummary(options, handlerFn)includes options in the call to diff --stat options and returns a DiffSummary
.env(name, value)Set environment variables to be passed to the spawned child processes, see usage in detail below.
.exec(handlerFn)calls a simple function in the current step
.fetch([options, ] handlerFn)update the local working copy database with changes from the default remote repo and branch, when supplied the options argument can be a standard options object either an array of string commands as supported by the git fetch.
.fetch(remote, branch, handlerFn)update the local working copy database with changes from a remote repo
.fetch(handlerFn)update the local working copy database with changes from the default remote repo and branch
.log([options], handlerFn)list commits between options.from and tags or branch (if not specified will show all history). Additionally you can provide options.file, which is the path to a file in your repository. Then only this file will be considered. options.symmetric allows you to specify whether you want to use symmetric revision range (To be compatible, by default, its value is true). For any other set of options, supply options as an array of strings to be appended to the git log command. To use a custom splitter in the log format, set options.splitter to be the string the log should be split on. Set options.multiLine to true to include a multi-line body in the output format. Options can also be supplied as a standard options object for adding custom properties supported by the git log command.
.outputHandler(handlerFn)attaches a handler that will be called with the name of the command being run and the stdout and stderr readable streams created by the child process running that command
.raw(args[, handlerFn])Execute any arbitrary array of commands supported by the underlying git binary. When the git process returns a non-zero signal on exit and it printed something to stderr, the commmand will be treated as an error, otherwise treated as a success.
.rebase([options,] handlerFn)Rebases the repo, options should be supplied as an array of string parameters supported by the git rebase command, or an object of options (see details below for option formats).
.revert(commit [, options [, handlerFn]])reverts one or more commits in the working copy. The commit can be any regular commit-ish value (hash, name or offset such as HEAD~2) or a range of commits (eg: master~5..master~2). When supplied the options argument contain any options accepted by git-revert.
.rm([fileA, ...], handlerFn)removes any number of files from source control
.rmKeepLocal([fileA, ...], handlerFn)removes files from source control but leaves them on disk
.stash([options, ][ handlerFn])Stash the working directory, optional first argument can be an array of string arguments or options object to pass to the git stash command.
.stashList([options, ][handlerFn])Retrieves the stash list, optional first argument can be an object specifying options.splitter to override the default value of ;;;;, alternatively options can be a set of arguments as supported by the git stash list command.
.tag(args[], handlerFn)Runs any supported git tag commands with arguments passed as an array of strings .
.tags([options, ] handlerFn)list all tags, use the optional options object to set any options allows by the git tag command. Tags will be sorted by semantic version number by default, for git versions 2.7 and above, use the --sort option to set a custom sort.
.show([options], handlerFn)Show various types of objects, for example the file content at a certain commit. options is the single value string or array of string commands you want to run
