RegexReplacer

A simple C# program that you can use to replace text in a specified regex/blob pattern of files.

Download

Visit Releases for an binary. Linux users can download the binary directly, and windows users have to extract the zip file to run it. This will be changed in the future when I have access to an .NET 5 windows VM to compile with again. Tracking in #1.

Building

Execute dotnet build on either the sln or RegexReplacer.csproj.

Why

I needed this for a massive replace on a large scale project based on a specific regex and blob. I thought others may find this useful as well and decided to release it. For that reason don't expect the best documentation nor support on this project.

Running

By default, you can just run the .exe on windows and the binary directly on linux. If no arguments are provided it will use regexreplacer.json in the same folder as configuration file. If an argument was provided however, it'll use that path/file for settings.

Configuration

By default, running the program once without an regexreplacer.json file in the working directory will create an example file. Using that file, you can configure how RegexReplacer will work.

regexreplacer.json:

{
  "patterns": [
    {
      "path": "/tmp/your_directory",
      "searchBlob": "*.*",
      "matcher": "aa\/",
      "replace": [
        {
          "from": "hello",
          "to": "goodbye",
        }
      ],
      "searchOptions": 1
    }
  ]
}

This pattern will change all files (recursively) inside the folder /tmp/your_directory where the path matches the regex aa/. Once it lists these files, it will try to replace the word hello with goodbye.

Note patterns is an array and multiple patterns are allowed.

/tmp/your_directory/aa/afile.txt

hello world, this is my great test file!

Will get changed to:

goodbye world, this is my great test file!

While /tmp/your_directory/adifferentfile.txt will not get changed.
