A customizable command line touch typing tutor

youtyper

youtyper is a customizable command-line touch-typing tutor.

You can easily add your customized lesson with text, even Python function.

Motivation

There're a lot of touch-typing tutor apps. However, most of the apps doesn't come with the flexibility to maximize my learning rate.

First, the flexibility of lessons.

For example, I'm pretty bad at distinguish "c" and "d", which lies vertically on keyboards, but most of apps provides rowwise lessons. I'm also not good at typing "y", "u", and "i", but most of apps also includes "o" and "p" in the lessons for these keys. Some apps provide lessons with custom texts, but which cannot be dynamically generated. And, I want to create lessons with Python.

Second, the flexibility of analytics.

I'm a pretty big fun of keybr.com, because of its beauty and detailed statistics. I may have spent more time watching the graphs than practicing. Though I can't create beautiful interfaces like them, I can provide more detailed statistics and even allow users to analyze their typing.

Naming

• "y","o","u","t","p","e",and "r" are all on the upper row of the keyboard
• These keys are why I created this app.
• This name may also indicates customizability of this app.

Install

pip install youtyper

Quickstart

youtyper: will start a standard lesson with standard analytics enabled.

Customize your lessons

Use --lesson_type to choose your lesson.

1. Load text to create lessons

   youtyper --lesson_type text --text_path path-to-your-lesson-text

   Other options available:

   • --disable_shuffle: Disable shuffling of lessons (default: false)
   • --num_lessons 10: lessons to take (default: None, repeat until exit)
   • --len_lessons 50: Number of maximum characters in a lesson (default: 100)

2. Load python script to enable custom lesson

   youtyper --lesson_type python --generator_path path-to-your-lesson-text -- generator_name YourLessonGeneratorClassName

   Use the specified LessonGenarator class to generate lessons. Example generators are available under examples.

3. Load built-in lessons

   youtyper --lesson_type built-in --lesson_name right_hand_home_row

   Use the built-in lessons. See lessons/README.md for available lessons.

Customize your analyzer

1. Use predefined analyzer

   youtyper ... --analyzer cpm error_rate

   • cpm: Character Per Minute
   • error_rate: The ratio of wrong key push

   Other options available:

   • --analyzer wpm: [To be implemented] Show words per minute
   • --ignore_consecutive_errors: [To be implemented] Ignore the consecutive error by the same character (deafult: false)

2. Use custome analyzer

   youtyper ... --analyzer_path path-to-your-analyzer-file --analyzer_name YourStatisticsClassName

   Use the specified Analyzer class to analyze lesson logs.Example analyzer are available under examples.

Build your own custom class

1. Custom Lesson

• You must provide a custom LessonGenerator to create your custom lessons.
  • LessonGenarator must be a iterator yields Lesson
    • LessonGenarator must implement __len__ method
    • Lesson is basically text to type and metadata.
  • Unknown command line options are passed to the LessonGenarator class as list.

2. Custom Analyzer

• You must provide a custom Analyzer to use your custom analytics.
  • Analyzer must generate printable text to show user, and dict to save with lesson.
    • Analyzer must implement analyze method which returns (Dict, str)
  • Unknown command line options are passed to the LessonGenarator class as list.
    • You can specify multiple Analyzer and all the unknown options are passed to all Analyzer.
      • Check your option is not shared by other analyzers unintentionally.

Lesson Log

For further analytics, youtyper saves every lesson log to the .youtyper directory under the user's homedir.

A lesson log is a json file named as yyyymmdd_hhmmss_[lesson_name]_[lesson_id].json.

The structure is as follows:

{
  "lesson_name": "right_hand_home_row",
  "lesson_id": "1",
  "command-line-options": {"lesson_type": "built-in", "lesson_name":"right_hand_home_row"},
  "text": "klj ;l;l;jjk ;ljl; kl;jkl jjlk ljk l; kl ;j",
  "keystrokes": 
  [
    {"timestamp": "2020/07/02 18:00:03", "key":  "k", "target":"l"},
    {"..."}
  ],
  "analytics": 
  {
    "cpm": {"overall": 100.0,"k": 70.6, "l": 116.4,"...": "..."},
    "error_rate": {"overall": 0.043, "k": 0.067,"l": 0.032,"...": "..."},
    "...": "..."
  } 
}
