Changes in version 0.2-2                        

  - The source code of the exams2forms package is now hosted on Codeberg
    at https://codeberg.org/zeileis/exams2forms where bugs can be
    reported in the issues and pull requests can be made etc.
    Development versions of the package can be conveniently installed
    from R-universe via: install.packages("exams2forms", repos =
    "https://zeileis.R-universe.dev")

                 Changes in version 0.2-1 (2026-05-05)                  

  - Answer entered in string forms were not processed correctly if the
    correct solution could be mapped to a number. Fixed now in webex.js.
    (Reported by Chad Worley in
    https://stackoverflow.com/questions/79934347)

  - Small fix in webex.js for the setting with show_tolerance = TRUE and
    n > 1.

  - The converter argument in exams2forms() was not used and has hence
    been dropped.

                 Changes in version 0.2-0 (2025-05-02)                  

  - Based on the package vignette, the R/exams web page has a tutorial
    for exams2forms: https://www.R-exams.org/tutorials/exams2forms/.

  - Some small improvements in webex.css and webex.js so that
    exams2forms output also renders correctly in jekyll projects, in
    particular with the feeling responsive theme used on
    https://www.R-exams.org/.

  - All exercise template pages on the R/exams web page now feature an
    interactive preview generated with exams2forms using three random
    variations of each exercise. See
    https://www.R-exams.org/templates/boxplots/ or
    https://www.R-exams.org/templates/lm2/ for two examples.

  - The function exams2forms() as well as all underlying forms_*()
    functions gained an argument obfuscate = TRUE which provides some
    basic obfuscation of the correct answers for all forms in the
    underlying HTML code. Thus, all correct answers are still stored in
    the HTML but, by default, they are not easily readable anymore.

  - The function exams2forms() gained additional arguments auto,
    show_filename, and show_tolerance, which are useful for inspecting
    exercises during their development. See exams2webquiz("lm2.Rmd",
    auto = TRUE) to see the results: all forms are pre-filled with check
    enabled and the display includes solution, tolerances, and the file
    name.

  - In forms_num() the correct answer is now assured to be formatted
    without scientific notation.

  - In the answer lists of single- and multiple-choice exercises single
    quotes are no longer escaped by forms_schoice() and forms_mchoice()
    so that expressions like $f'(x)$ render correctly.

  - The package now ships with some example exercises that illustrate a
    feature of exams2forms that is not (or not easily) available in
    other exams2xyz interfaces: regular expressions for the correct
    answers of string exercises. To generate a demo quiz with these you
    can use:
    
    exams2webquiz(c("geography2.Rmd", "email.Rmd"), regex = TRUE, n = 3,
    edir = system.file(package = "exams2forms"))
    
      - The exercise geography2.Rmd simply lists several solutions that
        are accepted using "or" regular expressions:
        ^(answer1|answer2|answer3)$
      - The exercise email.Rmd has a more complex regular expression for
        checking the validity of e-mail addresses.
      - Furthermore, geography.Rmd is a multiple-choice version of the
        geography2.Rmd exercise.

                 Changes in version 0.1-0 (2024-11-06)                  

  - New R/exams (https://www.R-exams.org/) interface for embedding
    exercises as (interactive) forms in R/Markdown or Quarto documents.

  - For an introduction see the package vignette:
    
    vignette("exams2forms", package = "exams2forms")

  - The idea and original code for inserting interactions into
    R/Markdown documents along with CSS and Javascript is adapted from
    the webexercises package, authored by Dale Barr and Lisa DeBruine.

  - The main function is exams2forms() which is typically used within
    R/Markdown or Quarto documents. The package provides two demo
    documents.
    
      - questions.Rmd: All questions set up indvidually.
      - quiz.Rmd: An entire quiz set up in one go.

  - Additionally, the function exams2webquiz() can be used to quickly
    set up and render a quiz document interactively based on a set of
    R/exams exercises. For example:
    
    exams2webquiz(c("swisscapital.Rmd", "capitals.Rmd", "fruit.Rmd",
    "function.Rmd", "lm2.Rmd"))
