使用nodegit

问题描述

var nodegit = require("nodegit");
var path = require("path");
var fse = require("fs-extra");
var repoDir = "../git_repositories/";

var repository;
var index;

//eventually need to pass in user here for some Metadata (author/committor info)
createGitRepository = (user,repositoryName) => {
  var newRepoDir = repoDir.concat(repositoryName);
  var fileName = repositoryName.concat(".txt");
  var fileContent = repositoryName.concat("DEFAULT CONTENTS");
  fse.ensureDir(path.resolve(__dirname,newRepoDir))
    .then(function () {
      return nodegit.Repository.init(path.resolve(__dirname,newRepoDir),0);
    })
    .then(function (repo) {
      repository = repo;
      return fse.writeFile(path.join(repository.workdir(),fileName),fileContent);
    })
    .then(function () {
      return repository.refreshIndex();
    })
    .then(function (idx) {
      index = idx;
    })
    .then(function () {
      return index.addByPath(fileName);
    })
    .then(function () {
      return index.write();
    })
    .then(function () {
      return index.writeTree();
    })
    .then(function (oid) {
      var author = nodegit.Signature.Now("Zaphod Beeblebrox","[e-mail]");
      var committer = nodegit.Signature.Now("Ford Prefect","[e-mail]");

      // Since we're creating an inital commit,it has no parents. Note that unlike
      // normal we don't get the head either,because there isn't one yet.
      var commit = repository.createCommit("HEAD",author,committer,"message",oid,[]);
      return commit;
    })
    .done(function (commitId) {
      console.log("New Commit: ",commitId);
    });
}

addAndCommit = (fileName,fileContent) => {
  nodegit.Repository.open(path.resolve(__dirname,"../.git"))
    .then(function (repoResult) {
      repo = repoResult;
      return fse.ensureDir(path.join(repo.workdir(),directoryName));
    }).then(function () {
      return fse.writeFile(path.join(repo.workdir(),fileContent);
    })
    .then(function () {
      return fse.writeFile(
        path.join(repo.workdir(),directoryName,fileContent
      );
    })
    .then(function () {
      return repo.refreshIndex();
    })
    .then(function (indexResult) {
      index = indexResult;
    })
    .then(function () {
      // this file is in the root of the directory and doesn't need a full path
      return index.addByPath(fileName);
    })
    .then(function () {
      // this file is in a subdirectory and can use a relative path
      return index.addByPath(path.posix.join(directoryName,fileName));
    })
    .then(function () {
      // this will write both files to the index
      return index.write();
    })
    .then(function () {
      return index.writeTree();
    })
    .then(function (oidResult) {
      oid = oidResult;
      return nodegit.Reference.nametoId(repo,"HEAD");
    })
    .then(function (head) {
      return repo.getCommit(head);
    })
    .then(function (parent) {
      var author = nodegit.Signature.Now("Scott Chacon","[e-mail]");
      var committer = nodegit.Signature.Now("Scott A Chacon","[e-mail]");

      return repo.createCommit("HEAD",[parent]);
    })
    .done(function (commitId) {
      console.log("New Commit: ",commitId);
    });
}
module.exports = {
  createGitRepository,addAndCommit
}

它成功创建了文件夹，文件和存储库，但抛出错误。我不确定该错误所指示的是什么，我无法通过逐步执行代码来解决？

似乎正在发生：

返回nodegit.Repository.init（path.resolve（__ dirname，newRepoDir），0）;

我觉得this可能与之相关，但并没有解决

解决方法

需要将.done更改为.then，最后

var nodegit = require("nodegit");
var path = require("path");
var fse = require("fs-extra");
var repoDir = "../git_repositories/";

var repository;
var index;

//eventually need to pass in user here for some metadata (author/committor info)
createGitRepository = (user,repositoryName) => {
  var newRepoDir = repoDir.concat(repositoryName);
  var fileName = repositoryName.concat(".txt");
  var fileContent = repositoryName.concat("DEFAULT CONTENTS");
  fse.ensureDir(path.resolve(__dirname,newRepoDir))
    .then(function () {
      return nodegit.Repository.init(path.resolve(__dirname,newRepoDir),0);
    })
    .then(function (repo) {
      repository = repo;
      return fse.writeFile(path.join(repository.workdir(),fileName),fileContent);
    })
    .then(function () {
      return repository.refreshIndex();
    })
    .then(function (idx) {
      index = idx;
    })
    .then(function () {
      return index.addByPath(fileName);
    })
    .then(function () {
      return index.write();
    })
    .then(function () {
      return index.writeTree();
    })
    .then(function (oid) {
      var author = nodegit.Signature.now("Zaphod Beeblebrox","[e-mail]");
      var committer = nodegit.Signature.now("Ford Prefect","[e-mail]");

      // Since we're creating an inital commit,it has no parents. Note that unlike
      // normal we don't get the head either,because there isn't one yet.
      var commit = repository.createCommit("HEAD",author,committer,"message",oid,[]);
      return commit;
    })
    .then(function (commitId) {
      console.log("New Commit: ",commitId);
    });
}

addAndCommit = (fileName,fileContent) => {
  nodegit.Repository.open(path.resolve(__dirname,"../.git"))
    .then(function (repoResult) {
      repo = repoResult;
      return fse.ensureDir(path.join(repo.workdir(),directoryName));
    }).then(function () {
      return fse.writeFile(path.join(repo.workdir(),fileContent);
    })
    .then(function () {
      return fse.writeFile(
        path.join(repo.workdir(),directoryName,fileContent
      );
    })
    .then(function () {
      return repo.refreshIndex();
    })
    .then(function (indexResult) {
      index = indexResult;
    })
    .then(function () {
      // this file is in the root of the directory and doesn't need a full path
      return index.addByPath(fileName);
    })
    .then(function () {
      // this file is in a subdirectory and can use a relative path
      return index.addByPath(path.posix.join(directoryName,fileName));
    })
    .then(function () {
      // this will write both files to the index
      return index.write();
    })
    .then(function () {
      return index.writeTree();
    })
    .then(function (oidResult) {
      oid = oidResult;
      return nodegit.Reference.nameToId(repo,"HEAD");
    })
    .then(function (head) {
      return repo.getCommit(head);
    })
    .then(function (parent) {
      var author = nodegit.Signature.now("Scott Chacon","[e-mail]");
      var committer = nodegit.Signature.now("Scott A Chacon","[e-mail]");

      return repo.createCommit("HEAD",[parent]);
    })
    .done(function (commitId) {
      console.log("New Commit: ",commitId);
    });
}
module.exports = {
  createGitRepository,addAndCommit
}
