# **Introduction to KeyboardSimulator** ![CRAN](https://img.shields.io/badge/CRAN-2.6.0-brightgreen) [![](https://cranlogs.r-pkg.org/badges/KeyboardSimulator)](https://CRAN.R-project.org/package=KeyboardSimulator) `KeyboardSimulator` is a package for R language that make users simulate keyboard event, cursor movement and mouse click with simple R function. This package provide 6 functions which are developed in C++: - `keybd.press()` Simulate keyboard key presses. Multiple keys can be pressed simultaneously by using `+` as separator. - `keybd.release()` Simulate the release of keyboard keys held by `keybd.press`. - `keybd.type_string()` Type a string with simulated keyboard input. - `mouse.click()` Simulate left and right button of mouse clicks. - `mouse.release()` Simulate the release of mouse button held by `mouse.click`. - `mouse.get_cursor()` Get current cursor coordinate of screen. - `mouse.move()` Move cursor to specific coordinate of screen. The supported keys are listed in `keyboard_value`. *** ## **FAQ** ### Does `KeyboardSimulator` support operating systems other than Windows? No, `KeyboardSimulator` is built on top of the [Windows API](https://docs.microsoft.com/en-us/windows/desktop/api/index) and is not compatible with other operating systems. ### This package doesn't work on my computer! How can I make it work? Open a [GitHub](https://github.com/ChiHangChen/KeyboardSimulator) issue and let us know what version of Windows you are using and what keyboard and mouse hardware you have connected. *** ## **Package Setup** ```r install.packages("KeyboardSimulator") library(KeyboardSimulator) ``` or ```r if (!require("devtools")) install.packages("devtools") devtools::install_github("ChiHangChen/KeyboardSimulator") library(KeyboardSimulator) ``` *** ## **Examples** #### **Simulate keyboard event** * **Press single key** ```r keybd.press("Enter") ``` * **Press multiple keys with `+` as seperator** ```r keybd.press("Alt+f4") ``` * **Hold keys with argument `hold=TRUE` and use `keybd.release` to release the held key** ```r keybd.press("Alt", hold = TRUE) keybd.press('Tab') keybd.release('Alt') ``` #### **Simulate mouse event** * **Get current location of cursor** ```r mouse.get_cursor() ``` ``` # Return the x,y coordinate of screen [1] 960 540 ``` * **Press mouse button** ```r mouse.click() mouse.click("right") ``` * **Move cursor to the center of screen on 1080FHD monitor** ```r mouse.move(960, 540) ``` * **Move cursor to the center of screen on 1080FHD monitor within 3 seconds** ```r mouse.move(960, 540, duration=3) ``` * **Drag an item to center of screen** ```r mouse.click(button = "left", hold = TRUE) mouse.move(960, 540) mouse.release() ``` *** ## **Developers** #### **Dependencies** It is highly recommended that you use the [RStudio IDE](https://www.rstudio.com/products/RStudio/) to develop this package. In addition to an [R installation](https://cran.r-project.org/bin/windows/base/), you'll also need to [install Rtools](https://cran.r-project.org/bin/windows/Rtools/) and a TeX distribution. [TeX Live](https://tug.org/texlive/) is a comprehensive distribution that seems to work well. Once you have cloned this repository, you'll need to download the build package dependencies. These dependencies are managed with `packrat` and can be restored by running ```r if (!require(packrat)) install.packages("packrat") packrat::on() packrat::restore() ``` *** ## **Documentation** The `roxygen2` R package is used to manage `KeyboardSimulator`'s documentation. Do not edit any of the files that have a warning comment at the top about manually editing those files! You can regenerate package documentation with the RStudio shortcut Ctrl+Shift+Enter, or by running ```r roxygen2::roxygenize() ``` The project is set up to do this whenever building and testing the package. *** ## **Other** * Put any C/C++/Fortran code in 'src'. * See [_Writing R Extensions_](https://cran.r-project.org/doc/manuals/R-exts.html) for more information.
