我搜索了Google和Stackoverflow,以获得如何编写相应代码的问题的答案 git commit -a -m" message" 在libgit2(https://libgit2.github.com)和C或C ++中。 但我找不到这个问题的准备和工作答案。 我使用的是libgit2-0.21。
下面是初始化git存储库,向其添加两个文件,并对这两个文件进行分阶段以便准备提交的代码。
我的问题是如何编码" git commit -a -m" msg"在libgit2?
#include <sys/stat.h>
#include <string>
#include <fstream>
#include <iostream>
#include <git2.h>
using namespace std;
int main (int argc, char** argv)
{
git_threads_init ();
// Create repository directory.
string directory = "repository";
mkdir (directory.c_str(), 0777);
// Initialize the repository: git init.
git_repository *repo = NULL;
int result = git_repository_init (&repo, directory.c_str(), false);
if (result != 0) cerr << giterr_last ()->message << endl;
// Store two files in the repository directory.
ofstream file;
file.open ("repository/file1", ios::binary | ios::trunc);
file << "Contents of file one";
file.close ();
file.open ("repository/file2", ios::binary | ios::trunc);
file << "Contents of file two";
file.close ();
// Run the equivalent of "git add ."
// Get the git index.
git_index * index = NULL;
result = git_repository_index (&index, repo);
if (result != 0) cerr << giterr_last ()->message << endl;
// Add all files to the git index.
result = git_index_add_all (index, NULL, 0, NULL, NULL);
if (result != 0) cerr << giterr_last ()->message << endl;
// Write the index to disk.
result = git_index_write (index);
if (result != 0) cerr << giterr_last ()->message << endl;
// Run the equivalent of "git commit -a -m "commit message".
// How to do that through libgit2?
// Run "git status" to see the result.
system ("cd repository; git status");
// Free resources.
git_index_free (index);
git_repository_free (repo);
git_threads_shutdown ();
return 0;
}
代码可以编译如下:
g++ -Wall -I/opt/local/include -L/opt/local/lib -lgit2 -o test git.cpp
以下是运行已编译二进制文件的输出:
On branch master
Initial commit
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: file1
new file: file2
答案 0 :(得分:5)
索引更新后
git_index_write_tree()
git_commit_create_v()
查看此结尾 test ,其执行以下等效内容
$ echo "test" > test.txt
$ git add .
$ git commit -m "Initial commit"
