In PaulESantos/pftctutor: Interactive Tutorials for PFTC Courses data

learnr (development version)

Breaking Changes

• Renamed the exercise_submission event to exercise_result and added the following fields:
• id - a randombly generated identifier that can be used to align with the associated exercise_result event.
• time_elapsed - the time required to run the exercise (in seconds)
• timeout_exceeded - indicates whether the exercise was interrupted due to an exceeded timeout. May be NA for some platforms/evaluators if that information is not known or reported.

New features

Minor new features and improvements

• Added an exercise_submitted event which is fired before evaluating an exercise. This event can be associated with an exercise_result event using the randomly generated id included in the data of both events.

Bug fixes

learnr 0.10.1

New features

Minor new features and improvements

• learnr gained the function learnr::tutorial_package_dependencies(), used to enumerate a tutorial's R package dependencies. Front-ends can use this to ensure a tutorial's dependencies are satisfied before attempting to run that tutorial. learnr::available_tutorials() gained the column package_dependencies containing the required packages to run the document. (#329)

• Include vignette about publishing learnr tutorials on shinyapps.io. (#322)

• learnr's built-in tutorials now come with a description as part of the YAML header, with the intention of this being used in front-end software that catalogues available learnr tutorials on the system. (#312)

• Add session_start and session_stop events. (#311)

Bug fixes

• Fixed a bug where broken exercise code created non-"length-one character vector". (#311)

• Fixed extra parameter documentation bug for CRAN. (#323)

• Fixed video initialization error caused by a jQuery version increase in Shiny. (#326)

• Fixed progressive reveal bug where the next section would not be displayed unless refreshed. (#330)

• Fixed a bug where topics would not be loaded if they contained non-ascii characters. (#330)

learnr 0.10.0

New features

• Quiz questions are implemented using shiny modules (instead of htmlwidgets). (#194)

• Aggressively rerender prerendered tutorials in favor of a cohesive exercise environment (#169, #179, and rstudio/rmarkdown#1420)

• Added a new function, safe, which evaluates code in a new, safe R environment. (#174)

Minor new features and improvements

• Added the last evaluated exercise submission value, last_value, as an exercise checker function argument. (#228)

• Added tabset support. (#219 #212)

• Question width will expand to the container width. (#222)

• Available tutorial names will be displayed when no name parameter or an incorrect name is provided to run_tutorial(). (#234)

• The options parameter was added to question to allow custom questions to pass along custom information. See sortable::sortable_question for an example. (#243)

• Missing package dependencies will ask to be installed at tutorial run time. (@isteves, #253)

• When questions are tried again, the existing answer will remain, not forcing the user to restart from scratch. (#270)

• A version number has been added to question_submission events. This will help when using custom storage methods. (#291)

• Tutorial storage on the browser is now executed directly on indexedDB using idb-keyval (dropping localforage). This change prevents browser tabs from blocking each other when trying to access indexedDB data. (#305)

Bug fixes

• Fixed a spurious console warning when running exercises using Pandoc 2.0. (#154)

• Added a fail-safe to try-catch bad student code that would crash the tutorial. (@adamblake, #229)

• Replaced references to checkthat and grader in docs with gradethis (#269)

• Removed a warning created by pandoc when evaluating exercises where pandoc was wanting a title or pagetitle. #303

learnr 0.9.2

• Fixed #136 by displaying full HTML messages (rather than just the text) if provided by the incorrect or the correct args to question(). (#146)

• Improved documentation for deploying learnr tutorials in Shiny Server. (#142)

• Fixed a highlight.js issue from rmarkdown 1.8. (#133)

• Fixed an false positive in the diagnostics system. (#141)

learnr 0.9.1

• Fixed a compatibility issue, so that existing tutorials don't break when using Pandoc 2.0. (#130)
