Splashscreen in text console with logo from ASCII characters
npm install asciiart-logo__asciiart-logo__ _renders a splash screen in text console with logo from ASCII characters._
Splash screen is a rectangular panel and logo is the application name rendered by ASCII-art fonts extended by optional additional information (author, application version, short desctiption, etc). Example console output from this project's package.json:
`` Console | '__| __| | | / _ \ / _

| / \ ___ ___(_|_) __ _ _ __| |_ | | ___ __ _ ___ |

``
__asciiart-logo__ can be used by starting of command line tools, web servers or REST API microservices as a visual feedback to the user or administrator about successful start of the application.
1. Download and install with command npm install asciiart-logo
1. See in action with command
Simplest usage is to provide the package.json file and call the method render to write out the splash screen to console:
` JavaScript`
const logo = require('asciiart-logo');
const config = require('./package.json');
console.log(logo(config).render());
The __asciiart-logo__ will render following information from the package.json:
* __name__ - rendered with ASCII-art font to dominate the splash screen
* __version__ - right-alligned so it will not "fight" for reader's attention
* __description__ - short information about the project
## Rich Usage: Explicit Parametrization
The main impression of the splash screen is shaped by the selection of the right ASCII-art font.
Number of characters of the logo in single line (parameter lineChars) controls word wrapping logic in logo rendering and indirectly the width of the panel.
You can adjust also padding and margin of the panel.
* __name__ - applicaiton name in ascii-art logo (name parameter in project.json defines name of the application)
* __font__ - ASCII-art font from the font gallery - default font is Standard
* __lineChars__ - length of line in name (ascii-art logo) for word wrapping
* __padding__ - space around the panel around text (like in CSS) - default is 5
* __margin__ - left space outside of the panel - default is 2
The text in splash screen is wrapped according the size of logo. Spaces, new lines, tabs are squeezed into single space. Text can be programmatically writen with functions:
* __left__ - text is alligned to left or wrapped
* __right__ - text is alligned to right or wrapped
* __center__ - text is alligned to center or wrapped
* __wrap__ - synonym to function _left_
* __emptyLine__ - add empty line into the panel
Method __render()__ must be the last one to call - it writes out the splash screen to console.
Default usage prints the splash screen with default color. Splash screen can be colored by parameters:
* __logoColor__
* __textColor__
* __borderColor__
Color can have following values:
* black, red, green, blue, yellow, magenta, cyan, white
* , bold-red, bold-green, bold-blue, bold-yellow, bold-magenta, bold-cyan, bold-white
