 # dengitool

-horrible scripting tool for microslop bindows 
+simple but horrible scripting tool focused on microslop bindows servers written in go
+
+---
+
+## example instalation
+
+> `dtool.exe` is portable, you can _use any directory_
+
+1. Create folder and copy `dtool.exe`. For example in `C:\dtooll`
+1. Add to env **`PATH`** your folder
+1. That's it! Open a terminal and try to run `dtool -h`
+
+## setup app
+
+example tree
+
+```
+config
+└───<application>
+    └───<module>
+            └───run
+                customscript.ps1
+            check.ps1
+            config.yml
+            fix.ps1
+            restart.ps1
+            start.ps1
+            stop.ps1
+```
+
+> **TIP:** you can leave only scripts that you need
+
+you can write scripts **in any language you want** which is supported by [built-in script runners](#built-in), OR you can write **your own** [custom runner](#custom-runners)
+
+#### check
+
+for checkking status you can use either your script or you can write in config.yml `check-url` [(details)](#config)
+
+#### restart
+
+you can define restart script or it would use start and stop
+
+#### config
+
+currently there are config for `application`, example:
+
+```yaml
+name: my-application
+```
+
+and for `module`
+
+```yaml
+name: my-module
+#
+check-url: https://example.com
+# or
+check-url: https://example.com 200
+# or even
+check-url: https://example.com 200 Test%20Body%20Text
+# or don't define at all
+#
+```
+
+for now that's it.
+
+## usage
+
+Usage:
+
+```
+dtool [application] [action] [module] [flags]
+```
+
+Flags:
+
+```
+ -h, --help           help for dtool
+      --list           list configured applications and modules
+      --list-runners   list configured script runners
+      --silent         suppress all output
+      --verbose        enable debug output
+```
+
+you can use `everything` for `application`
+
+just `dtool` is alias for `dtool everything check`
+
+#### actions
+
+|                                |                                                        |
+| ------------------------------ | ------------------------------------------------------ |
+| `check/fix/restart/start/stop` | runs it's script [(or check have url defined)](#check) |
+| `run [script name]`            | runs script in `run` subdirectory                      |
+
+## runners
+
+dengitool automaticly detects available script extension
+
+#### built-in
+
+| name               | extension |
+| ------------------ | --------- |
+| Windows Executable | `.exe`    |
+| PowerShell Script  | `.ps1`    |
+| Python             | `.py`     |
+| CMD Batch File     | `.bat`    |
+| NodeJS             | `.js`     |
+
+#### custom runners
+
+you can create your own runners
+
+for this, you need to create a .yml file at folder `runners` near dtool.exe
+
+you can **override** script for built-in extension
+
+**here is an example:**
+
+```yaml
+# runners/bun.yml
+name: My Bun Runner
+extension: .ts
+runner: bun run %v
+```
+
+> `%v` - absolute script path
+
+now you can see it in `dtool --list-runners`
+
