tflori/hugga

library for console applications with input and output handling

tflori/hugga

, _(*1)

PHP library for console applications. It supports formatting of messages and tables as well input handling with choices., _(*2)

Installation

Like all my libraries: only with composer, _(*3)

$ composer require tflori/hugga

Basic usage

<?php

$console = new Hugga\Console;
$name = $console->ask('What is your name?');
$console->line('${fg:white;bg:white;bold}Nice to meet you ' . $name . '!');

$console->line('You will see this', Hugga\Console::WEIGHT_NORMAL);
$console->line('You will not see this', Hugga\Console::WEIGHT_LOWER);
$console->increaseVerbosity();
$console->line('No you can see this', Hugga\Console::WEIGHT_LOWER);
$console->line('But this is just a debug message', Hugga\Console::WEIGHT_DEBUG);
//$console->setVerbosity(Hugga\Console::WEIGHT_DEBUG);
//$console->debug(
//    ['key' => 'value', 'recursive' => ['string', 42, null, true]],
//    Hugga\Console::DEBUG_PRETTY ^ Hugga\Console::DEBUG_COLOR
// );

Documentation

There is no documentation yet except this api reference. For some examples also have a look at examples/test.php and try them yourself with php vendor/tflori/hugga/examples/test.php., _(*4)

Also, there is an example how to create a paginated table with existing features in examples/paginated-table.php'., _(*5)

Features

Some features are still planned but a lot of features are available and they are enough for start and replacing symfony/console., _(*6)

Output Handling

• Drawings: a mechanism to stay at the end of your output while other output is printed above (clocks, progress bars etc.)
• Weighted output: just output and hugga will handle if the user want's to see it or not (verbosity)
• Formatting output: easy formatting with combined expression (example: ${red;bold}text${r})
• Output tables: easy to use tables with a lot of formatting features:
  • Predefined format: configure the formatting once and for all later tables
  • Borders: enable or disable borders (borders inside: between rows)
  • Padding: left and right padding inside cells
  • Repeat headers: repeat headers every nth row
  • Header style: define styles used for headers
• Progress bars: smooth progress bars with 8 steps (utf-8) and other formatting features:
  • Undetermined: throbber that spins between edges
  • Update rate: instead of define after how much steps the progressbar should update (symfony/console) you define how much time has to elapse before redrawing
  • Characters: change the characters used for the progress bar
  • Throbber: change the throbber used for undetermined progress bar
  • Floating point steps: use floating point numbers

Input Handling

• InputObserver: directly access the keyboard without writing the output to console
• EditLine fix: edit line (replacement for read line) can not read single key presses
• ReadLine: use read line for reading from stdin if available
• Read chars: read a specific amount of characters (multibyte safe)
• Read until: read input until a specific string appears (example: \n.\n)
• Simple question: a simple question with default value
• Confirmation: a question with the choice between y(es) and n(o) (characters can be changed)
• Choice: a question to choose between a list of options
  • Interactive by default: choose with cursor keys and select with enter using InputObserver
  • Return key: return the key instead of the value (default for assoc arrays)
  • Limit: change the limit of visible options (for interactive version)

Planned features

• Debug output: output variables in a human readable format with highlighting
• Interactive tables: scroll through tables using cursor keys and pagination
