Go deep into the secret of Git Commit: Use git show
to view basic changes. Use git log --patch to display modifications in "patch" form. git diff .. Compare the differences between two commits. git log -G "regular expression" filters commits via regular expressions. git log --pretty=format:"%H %s" View the commit log concisely.
How to get a glimpse of the secrets of Git Commit
Are you curious about what secrets are hidden in Git commit? It is not just a simple modification record, it contains the context of project evolution and is the key to understanding code evolution. Want to know how to view commit content efficiently? Don't worry, listen to me in detail. I will take you deep into the bottom of Git and unveil the mystery of commit.
Start with the most basic one, git show <commit_hash></commit_hash>
, which may be the first command you come into contact with. It can directly display the change information of the specified commit, including modified files, code differences, etc. commit_hash
is the string of characters that look like the Book of Heaven, the unique identifier of each commit. Remember, don't underestimate this command, it is the cornerstone of your exploration of commit content.
But git show
is not enough, especially when commit involves a lot of file modifications, the output information will appear lengthy and messy. At this time, you need more refined tools. git log --patch
, this command will display each commit modification in the form of a "patch", clearly displaying newly added, deleted and modified lines. With the -n
parameter, you can control the number of commits displayed to avoid information overload. If you only want to see the modifications of a few specific files, add the -- <file></file>
parameter, such as git log --patch -- <src></src>
to only display the modification history of the src/main.cpp
file.
Going further, if you want to compare code while viewing commit, git diff <commit_hash1>..<commit_hash2></commit_hash2></commit_hash1>
will be your weapon. This command will compare the differences between the two commits, allowing you to intuitively see the evolution of the code. Use it to compare adjacent commits to clearly see the specific modifications of each commit. Remember, .. symbol indicates range, you can also use it to compare branches, labels, etc.
However, no matter how powerful the tool is, you need to know how to use it. For example, if you only care about specific types of file modifications, you can combine git log -G"正則表達(dá)式"
to filter commit. This command will look for commits containing specific regular expressions, allowing you to quickly locate changes of interest. Using regular expressions flexibly, you will find that it can help you solve many difficult problems.
Finally, don't forget git log --pretty=format:"%H %s"
, which is a concise way to view commit logs. It only displays the hash value and commit information of commit, suitable for quick browsing project history. Flexible use of various --pretty
options, you can customize the output format to meet various needs.
After all, there is no only "best" way to view Git commit content, depending on your specific needs and scenarios. Only by mastering these commands and techniques can you easily find the information you want when facing the huge project history. This is not just about learning to use commands, but more importantly, understanding the underlying operating mechanism of Git, so that you can truly master the essence of Git. Only by practicing more, trying more, and exploring constantly can you become a true Git master.

The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.

To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X

User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.

To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction

This article elaborates on two main methods to realize call hold and unhold in Twilio. The preferred option is to leverage Twilio's Conference feature to easily enable call retention and recovery by updating the conference participant resources, and to customize music retention. Another approach is to deal with independent call legs, which requires more complex TwiML logic, passed, and arrived management, but is more cumbersome than meeting mode. The article provides specific code examples and operation steps to help developers efficiently implement Twilio call control.
