substitutions.\n\n![logo](/Images/logo.png)\n\n------------------\n\n## 👋 Introduction\n\nI decided to develop **RegexCon** as a solution for a third-party application that is written in a scripting language with limited Regex capabilities, but that third-party application supports running external apps, and this is where **RegexCon** comes into play for me, bridging the gap by enabling that third-party application to execute regular expression substitutions as required.\n\n**RegexCon** could be used, for example, in a for-loop of any programming language to perform file renamings.\n\nI'm convinced you would find additional scenarios where this tool proves invaluable to you!.\n\n## ‼️ Limitations\n\n**RegexCon** relies on the .NET regex engine and it utilizes its pattern syntax. While most common regex pattern syntax from other languages will work properly with **RegexCon**, it's important to note that each programming language has its own regex implementations, which may include minor syntax differences and/or limitations. For instance, a named group in PHP is written differently than in .NET. The responsibility for syntax adaptation lies with the end user.\n\n## 📝 Requirements\n\n- Microsoft Windows OS.\n\n## 🤖 Getting Started\n\nDownload the latest release by clicking [here](https://github.com/ElektroStudios/RegexCon-Performs-RegEx-substitution-via-command-line/releases/latest),\n\n#### Syntax\n    RegexCon.exe /I=(input) /E=(expression) /S=(substitution)\n\n#### Switches\n    /Input        or /I | The input string.\n    /Expression   or /E | The regular expression.\n    /Substitution or /S | The substitution string.\n    /MatchCase    or /M | Matches characters in a case-sensitive manner.\n    /?                  | Shows this help.\n\n#### Switch value types\n---------------------------------------------------------\n\t/Input        or /I | Any string\n\t/Expression   or /E | Any string\n\t/Substitution or /S | Any string\n\t/MatchCase    or /M | True/False\n\n#### Usage examples\n---------------------------------------------------------\n\t( Regular string substitution. )\n\tRegexCon.exe /I=\"Hello World\" /E=\"^(.+)\\s(.+)$\" /S=\"$2 $1\" /M=True\n\n\t( Named-group string substitution. )\n\tRegexCon.exe /I=\"Hello World\" /E=\"^(?\u003cone\u003e.+)\\s(?\u003ctwo\u003e.+)$\" /S=\"${two} ${one}\"\n\n## 🔄 Change Log\n\nExplore the complete list of changes, bug fixes, and improvements across different releases by clicking [here](/Docs/CHANGELOG.md).\n\n## ⚠️ Disclaimer:\n\nThis Work (the repository and the content provided in) is provided \"as is\", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose and noninfringement.
