How to use vim macro to speed up your complex find/replace operations in vim / ideavim

Yesterday, I need to replace a string ClassName with List<ClassName> many times in a few files, and the ClassName varies. Manually doing it again and again is tedious and mistake prone, which is what I hate. Here's the solution

First, record a macro,

  1. move cursor on any letter of the target ClassName
  2. qa
  3. ysiw>
  4. Insert
  5. List
  6. Esc
  7. q

Second, replay the macro, move cursor to another occurrence of ClassName,

@a

Third, replay the same macro as many times as you want: move cursor to any other occurrences, simply type

The feeling is so good to let a computer do what you want it to do!

and here's the Reference where I learnt how to use vim macro. TL;DR;

Delete to beginning of current word in Bash

Instead of pressing backspace repeatedly, press ESC then Backspace.

Multiline matches with ripgrep (rg)

The key is the dotall modifier (?s). It helped out me today! by the way, my final match expression is

rg --pcre2 -U '(?s)\.Initialise\([^,]+,\s*([^,]+),\s*\1(?:,true|false)?\);'

rg is a so fast and so powerful tool in my daily use, I love it!

[Solution]Microsoft.AspNetCore.Http was marked deprecated

Remove those deprecated NuGet packages, use the ASP.NET Core shared framework instead

With the release of .NET Core 3.0, many ASP.NET Core assemblies are no longer published to NuGet as packages. Instead, the assemblies are included in the Microsoft.AspNetCore.App shared framework, which is installed with the .NET Core SDK and runtime installers. For a list of packages no longer being published, see Remove obsolete package references.

As of .NET Core 3.0, projects using the Microsoft.NET.Sdk.Web MSBuild SDK implicitly reference the shared framework. Projects using the Microsoft.NET.Sdk or Microsoft.NET.Sdk.Razor SDK must reference ASP.NET Core to use ASP.NET Core APIs in the shared framework.

To reference ASP.NET Core, add the following element to your project file:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>

</Project>
