Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Open the ReactNotes.xcodeproj in the ios/ folder in Xcode."

A block of code is set as follows:

NSURL *jsCodeLocation;

/**
* Loading JavaScript code - uncomment the one you want.
*
* OPTION 1
* Load from development server. Start the server from the repository root:
*
* $ npm start
*
* To run on device, change `localhost` to the IP address of your computer
* (you can get this by typing `ifconfig` into the terminal and selecting the
* `inet` value under `en0:`) and make sure your computer and iOS device are
* on the same Wi-Fi network.
*/

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

/**
* OPTION 2
* Load from pre-bundled file on disk. To re-generate the static bundle
* from the root of your project directory, run
*
* $ react-native bundle --minify
*
* see http://facebook.github.io/react-native/docs/runningondevice.html
*/

//jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

Any command-line input or output is written as follows:

# cp /usr/src/asterisk-addons/configs/cdr_mysql.conf.sample
     /etc/asterisk/cdr_mysql.conf

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Select Run and under the Info tab change Build Configuration from Release to Debug."

Note

Warnings or important notes appear in a box like this.
