Regex

Project started: 15/11/2019, Last updated: 15/11/2019

This is a C++ module for Garry's Mod which gives developers access to the Regular Expressions string matching standard. I wanted to make this because Lua Patterns are limited in functionality and useless to learn if you've already learned Regex (also when there's already a standard in place they should never have been created in the first place)

Installation

1. Download the latest release binary file for your operating system (win32 for Windows, osx for MacOS and linux for Linux)
2. Rename the DLL prefix to match the realm you'll be using it on. (e.g. rename it to gmsv_regex_win32.dll if you're using it serverside on Windows, or gmcl_regex_win32.dll if you're using it clientside on Windows, etc.)
3. Navigate to your server's root directory (where srcds.exe, garrysmod, bin, etc. are)
4. Create a new folder inside garrysmod/lua/ called bin if it doesn't already exist.
5. Place the renamed module (dll) into that folder.
6. Use the module in any Lua script by calling require("regex").

Usage

Here is a basic example on how to use this module:

require("regex")
local message = "viral32111<76561198168833275,STEAM_0:1:104283773> said \"Hello World!\""
local regularExpression="^(.+)<(\\d{17}),(STEAM_\\d:\\d:\\d+)> said \"(.*)\"$"
local matches = regex.match(message,regularExpression)
PrintTable(matches)

The output of this would be:

0       =       viral32111<76561198168833275,STEAM_0:1:104283773> said "Hello World!"
1       =       viral32111
2       =       76561198168833275
3       =       STEAM_0:1:104283773
4       =       Hello World!

Generating a project

Run build.bat to generate a Visual Studio 2019 for Windows using the supplied premake5 configuration. This will create a new folder called project which will contain the Visual Studio project/solution files.

Building (Visual Studio 2019)

Once you've made your changes to the source code, press CTRL+B (or Build > Build gm_steam). This will generate the .dll file inside a build folder.
