Using Go Dep to Manage Dependencies

dep is a dependency management tool for golang. If you have done any software development before, dep is similar to npm, pod or pip. In simple words, it is a package manager to manage your project’s third party libraries. How to install it There’s a few ways to install dep. Personally I prefer to install it with Homebrew $~ brew install dep Initializing a project with dep To initialize it in your go project, go to your project directory and run the following

How to Change Git Branch Name

A quick one. Here’s how to change your git branch name: If you want to rename of your current local branch: git branch -m new-branch-name If you want to change the name of a different local branch git branch -m old-branch new-branch-name That’s it. Bye.

Dev Tweets #1

Collections of tweets that I find useful. 1. Julia Evans on performance reviews on surviving performance reviews pic.twitter.com/R7ZvxAPa3W — 🔎Julia Evans🔍 (@b0rk) August 22, 2018 2. Chris Wagner on using Xcode run script to notify us when running production environment If you use Xcode Schemes to differentiate between connecting to Production and Staging environments this is a nice little reminder. I’ve often had brief panic attacks that I was testing in production.

Set Default Git Push Behaviour

I tend to forget that I have to specify the current branch name when pushing it to a remote. For example: $~ git push or like this $~ git push -u origin Either way, these commands tend to fail when I haven’t yet set the upstream branch. git will return an error similar like this: fatal: The current branch develop has no upstream branch. To push the current branch and set the remote as upstream, use git push --set-upstream origin <INSERT BRANCH NAME HERE> To avoid this, I have to set the upstream branch name explicitly first before pushing it to the remote repository.

Set zsh as default shell To set is as default shell, run the following in your terminal:

Diff So Fancy

I find it quite hard to make sense of the output from git diff. Let’s just say that it is somewhat off-putting. diff-so-fancy is an open source project to solve this problem and help make your diff much less uglier. Installation There are a lot of ways to install it but I prefer to install all my tools with Brew. So run the following in your terminal: $~ brew install diff-so-fancy Configuration To use diff-so-fancy, you have to set it up globally.

Viewing Diff Since Latest Git Pull

To view the changes between your latest git pull $~ git pull origin $~ git diff @{1}.. @{n} means the n-th previous value of HEAD. You can refer the official docs on reflog Shortnames for more. p/s: I am currently trying to dissociate myself from becoming too dependent on SourceTree for daily git operations.
