Git side-by-side diff in tig with meld

January 20, 2022

Side-by-side diffs are more readable to me than in-line diffs.

Long time ago, I started using Meld to display them when working with git. But I always needed to manually specify branch or commit names. This week I finally spent some time and found a way to invoke Meld directly from tig, so that I can see the diff side-by-side while browsing a commit history in tig (for example, when I want to review a proposed branch containing 10 new commits, and I want to inspect each of them individually). Here’s a short howto.

Implementing gRPCweb with Istio Envoy

June 10, 2019

This is a post which was about how web applications can benefit from gRPC by leveraging a gRPC sub-project called gRPC-Web along with Istio.

gRPC-Web addresses a shortcoming in the core gRPC framework: the fact that it doesn’t work so well with web applications running on browsers. That’s because even though most browsers support HTTP/2 and gRPC is based on HTTP/2, gRPC has its own protocols that web applications must understand in order to work properly with it. But web applications do not have this capability because browsers don’t support gRPC out of the box. Developers are increasingly looking to benefit from the advantages the core gRPC framework confers beyond backend microservices, thus gRPC-Web was born.

Git Submodule

July 17, 2018

基于公司的项目会越来越多，常常需要提取公共的library提供给多个项目使用，但是这个library怎么和git在一起方便管理呢？

我们需要解决下面几个问题：

• 如何在git项目中导入library?
• library在其他的项目中被修改了可以更新到远程的代码库中?
• 其他项目如何获取到library最新的提交?
• 如何在clone的时候能够自动导入library?

解决以上问题，可以考虑使用git的submodule来解决。
