- Use HTML input elements in the Table UI rather than textareas when there is only 1 row per cell to reduce confusion when student hits Enter.
- Set specific column widths for SQL questions for compatibility with latest sqlite3.
- Change multilanguage question type so that answer code cannot be entered until a language has been selected but the user can step through the question (unanswered) without being required to select a language.
- Prevent grading of an unchanged preloaded answer.
- Add instructorhtml functionality to combinator grader so that a teacher can see HTML feedback that's hidden from student.
- Changed implementation of per-user rate throttling for web-service traffic to reduce the risk of log-manager SQL queries causing hangs (if that was indeed happening - problem was never fully diagnosed).

- Improve testing by turning off alerts when behat is running, plus other tweaks.
- Some documentation tweaks.
- Add uninstall instructions to Readme.md

- Make Behat tests a bit faster and more robust (Thanks Tim Hunt)
- Bug fix: exporting of questions with missing prototypes was failing.
- Add specific capability (qtype/coderunner:viewhiddentestcases) for viewing hidden test cases (default to existing built-in moodle/grade:viewhidden). Thanks Tim Hunt.
- Implement missing failMessage() method in HTML UI plugin, which resulted in an alert plus a JavaScript error message on the console rather than the expected warning message on the answer box.
- Stop-and-read-feedback option added.
- New experimental web service added that allows AJAX access to the CodeRunner sandbox (usually Jobe). Disabled by default. Supports the new experimental ace_inline_code filter (find it on github).
- Allow a comma-separated list of Jobe servers, from which one is randomly selected for any given job.
- Improve error handling when a combinator template grader fails, particularly with PostgreSQL servers.

- Add QUESTION.stepinfo to the Twig environment. This is a record with attributes preferredbehaviour, numchecks, numprechecks and fraction allowing authors to provide more elaborate feedback according to quiz mode and previous submissions.
- Add a macro ___textareaId___ to the HTML-UI that gets replaced by the id of the textarea element that the HTML-UI is operating on.
- Add special __twigprefix__ that, if defined in a question's prototype, provides content (e.g. Twig macros) that is inserted at the start of all Twig-expanded question fields.

- Bug fix: nodejs programs in ESM style were breaking. So change filename extension to .js
- Bug fix: Ace plugin was generating duplicate (and wrong) ids when multiple ace editors were present in a form.
- Bug fix: Ace editor was not being initialised to the correct language with multilanguage questions for which an explicit default language was specified.

- Bug fix: customising a question to use a non-standard Jobe server did not work if that server required an API key.
- Several documentation tweaks.
- Correct faulty documentation of import of html module within Twig and misuse of htmlentities in documentation.
- Bug fix: displaying the question author's solution to a question with the UI plugin explicitly set to None generates a PHP warning regarding an undefined constant fieldid.
- Bug fix: The Show Differences button was comparing the wrong two columns in Moodle 3.9.
- Add a linklabelreldist template parameter to the GraphUI to allow positioning of link labels at relative distances other than 0.5 along the link. Supported only with straight links.
- Two tweaks to the test suite.
- Bug fix: viewing of combinator grader outputs from previous versions of CodeRunner gave Undefined property: $outputonly PHP Notices.
- Add graphui demo question to samples.
- Add a 'showoutputonly' option to combinator template graders for use in 'sandpit' questions that allow students to experiment with code and see text and/or image output without penalty.
- Include a demonstration of the showoutputonly option in the samples folder.
- Bug fix: Prevent PHP Notice Undefined property: qtype_coderunner_question::$parameters when viewing a question without template parameters.

- Display sample answer using the selected user-interface wrapper (e.g. Ace) rather than just showing the straight text version.
- Replace Ace editor code with the latest full source version rather than an older minimised version. This turns out to greatly speed up the Ace editor loading, because the Moodle JavaScript minimiser choked when re-minimising the code.
- Bug fix: combinator template grader questions were being run in multiple Jobe submissions - one per test - when standard inputs were provided to the tests and Allow multiple stdins was not checked.
- Bug fix: Questions using gapfiller_ui did not allow editing of sample answer when the html code source was the first test case rather than globalextra.

- Regression fix: questions using the Twig STUDENT variable were not able to be correctly reviewed by a teacher after submission by student.
- Regression: upgraded Twig barfs on questions with null (as opposed to empty string) template parameters.
- Add a new experimental Ajax service that allows a question to display the question specification from a pdf file within a .zip support file, such as a standard ICPC exported programming contest question. Alpha version, still undocumented.

- Lots of minor edits to reduce style-checker warnings
- Addition of a globalextra field to all questions for use by question authors as a parameter global to all tests.
- Various enhancements and refactoring of TableUI including addition of a table-row-labels template parameter.
- Modify the still experimental and undocumented HtmlUI to get the raw HTML from the new globalextra field rather than via a template parameter.
- Bug fix: UI plugins that depend on template parameters, notable TableUI, broke if Twig code was used within the template parameters, e.g. for randomisation.
- Add table_locked_cells template parameter to Table UI
- Bug fix: student file attachments don't work in conjunction with author-supplied support files.

- Add youtube video links to Readme.md
- Styling improvements for input areas (thanks Tim Hunt).
- Add a new experimental feature that allows students to attach files to their submissions. The attached files are loaded into the working directory during the run.
- Add a Feedback dropdown to the question authoring form that allows the question author to display or hide the result table regardless of the behaviour mode chosen for the quiz.
- Fix bug in missing prototype error message (extraneous junk included, due to an exception being thrown).
- Bug fix: answerbox preloads of greater than ~1k generated debugging error messages (if developer-level messages were enabled). Thanks Tim Hunt.
- Bug fix: Twig-all was not being applied to the question's General Feedback.
- Improve handling of a failed unserialise of a legacy question attempt, which can (rarely) occur if a complete course, including student activity attempts, is moved between sites with different Moodle versions or database charsets.
- Improve handling of Twig errors when editing questions that use TwigAll in conjunction with ValidateOnSave.
- Bug fix: installing CodeRunner on Moodle 3.5 with error debug messages enabled resulted in messages "Error: mdb->get_record() found more than one record!" when browsing the question bank. Alternatively, if CodeRunner was installed on a freshly built Moodle 3.5, the CR_PROTOTYPES category became a proxy for the Top category in the system category and its name was hidden.
- Fix broken PHP question type and add test cases for it.

- Improve error message when duplicate question prototypes are found.
- Bug fix: behat export test not working with latest Moodle versions (Thanks Tim Hunt).
- Fix error in Privacy Provider (failing with PHP versions 7.x).Thanks to Sam Marshall.
- Refactoring to allow repair of questions with missing prototypes via the usual author editing form. Plus improved error messages in questions that use such broken prototypes.
- Addition of a TableUI user interface plugin that presents students with a table to fill in rather than a single text area. This supports a new experimental python3_testing question, where the student must supply a set of tests, given a specification.
- Improve error messages if a UI plugin doesn't load in time (usually the Ace editor).
- Implement Moodle privacy API for GDPR compatibility. This involves simply implementing the "null provider" class, essentially declaring that CodeRunner does not record any personal data about users.
- Add an experimental administrator script that deletes entire empty question category subtrees.
- Use language strings to document built-in questions rather than the question text to enable translation via AMOS.
- Reduce time for which the GraphUI displays the serialised answer during question submission.

- Miscellaneous bug fixes including:
- Questions with missing prototypes were breaking the display of the list of all questions in a quiz in Moodle 3.5.
- Bug in skool-is-kool take 2 sample question.
- Column header in the 'For example' table did not use a proper language string, so not subject to translation.
- Author editing form Ace editor panels were too narrow in Moodle 3.5 with Clean theme (and probably other non-Boost themes)
- Prototypes for java-method, octave-function, python2 and python3 questions were all broken on Windows-based Moodle servers.
- Some combinator template graders were failing with PHP 7.2.
This is a maintenance release.
- Bug fix: Show Differences button was not displayed on non-English-language sites.
- Minor tweaks and documentation updates.
- Add randomisation capabilities so that students can be presented with a randomly generated question variant when they start a question in a quiz. Randomisation is achieved by the use of Twig expansion of the template parameters field (assumed to include at least one call to the Twig random function) followed by Twig expansion of all other question fields using the expanded template parameters as a Twig environment.
- Add a Reset answer button to the student question answer page if the answer box contains preloaded content.
- Add function set_random_seed to Twig for use with the question randomisation, e.g. to ensure that a student always sees the same variant of a question no matter how often they attempt it.
- Add id field to the Twig STUDENT variable, e.g. for use with the above.
- Use Ace editor for template-parameters field.
- Add Twig All and Hoist template parameters checkboxes to the authoring interface for use with randomisation and to simplify template authoring in general.
- Add fontsize parameter to the GraphUI plugin.
- Fix a long-standing bug that caused questions to be flagged as incomplete after earlier having been marked correct even though the answer had not been altered. This turned out to occur if the student's answer began with a blank line.
- Improve question author feedback in the event of Twig errors.
- Miscellaneous code-cleaning and minor bug fixes.
- Add multilanguage program question type to base set, plus various changes to UI-handling code to allow student to select a language in such questions.
- Allow UTF-8 output from programs, if Jobe server is configured to allow this.
- Implement UI plugin architecture to allow different JavaScript plugins to manage the question answer textarea and related textareas in the question authoring form.
- Incorporate the GraphUI plugin from Emily Price into the new plugin architecture (thanks Emily).
- Add directed and undirected graph prototypes to the built-in prototype set.
- Fix bug with the auto-correcting of test cases that fail during validation. If the author changed the ordering of testcases via the "ordering" field, the wrong test case was getting updated. Resolved by preventing re-ordering during validation, deferring it until question is finally saved.
- Fixed bug in IdeoneSandbox - language name strings were no longer appropriate. However, this sandbox should be regarded as deprecated and will be removed some time in the future.
-
Incorporate changes from abautu (Andrei Bautu) to allow question authors to update test case 'expected' fields directly from a table of test failures generated by running the sample answer during validation of the question author form. Thanks Andrei.
-
Added an experimental script /question/type/coderunner/downloadquizattempts.php to dump the database info on all student quiz activity to a spreadsheet. The data includes the submitted answers to both prechecks and checks, with timestamps. The export format is experimental and may change in the future. A Python module quizattempts.py is included too and is the recommended way to deal with the quiz attempt download spreadsheet.
-
Bug fix: a submitted answer of '0' (an edge case that might be possible when student answer is not code) was being rejected as an empty response, due to the use of PHP's empty function. Thanks to David Bowes for the fixes here.
-
Added SQL prototype and 2 simple samples (experimental).
-
Bug fix: testsplitterre and allowmultiplestdin fields of author form were not being correctly initialised when a new combinator question type was downloaded with AJAX.
- Bug fix: result table cells not being sanitised since commit of 19/5/17
- Bug fix: combinator template grader result tables were not hiding hidden rows from students but merely colouring them darker.
- Add allow_multiple_stdins option for advanced use of combinator templates. This option disables the usual behaviour of running combinator templates once for each test when any tests have standard input defined. When enabled, the combinator is given all testcases (as when standard input is not present) and must itself manage the switching of standard inputs between tests.
- Bug fix: All-or-nothing checkbox was not labelled when using Clean theme
- Bug fix: All-or-nothing grading was not working with per-test-case template graders - students were getting partial marks.
- Generate a validate-on-save error message when using a combinator template grader that has a test-results table.
- Change Runtime Error message to just Error since it's not always clear what is runtime versus compile time.
- Change DB type of templateparams to text (was char(255)) to allow for more elaborate template parameters.
- Use text area for template params rather than a one-line entry field in order to cater for longer multi-line template parameters
- Update the uocprototypes.xml file in the samples directory to the latest version.
- Incorporate style changes from Open University (thanks Mahmoud Kassaei) for improved accessibility of the Ace editor.
- Fix bug in display of "For example" table when question has customised columns/headers.
- Improve various tests, e.g. fork bomb.
- Some documentation updates.
- Major bug fix: when grading of questions when precheck enabled, if a student's last submission to a question prior to closing the quiz was a precheck that passed, the question would be marked correct.
- Bug fix: sample answer and answer preload fields of author form were not using the correct Ace language when the question type was first set.
- Bug fix: validate on save not working with support files on the first save of the question.
- Bug fix: Show Differences button was not working in Edge browser.
- Bug fix: questions with precheck=selected were not being correctly saved in course backup.
- Various documentation and error message tweaks + code tidying.
- Fix broken code in some of the sample files, update others.
- Fix occasional mishandling of whitespace by Show Differences button.
- Fix bug (introduced in 3.1) in display of hidden test cases to students (rather than being suppressed, the hidden test cases were being displayed as repeated versions of the preceding visible test).
- Refine handling of Jobe sandbox errors: improve error messages and ensure no penalty is applied.
- Replace term "Pre-check" with "Precheck" throughout.
- A couple more tweaks to improve appearance with Boost theme
- Add administrator script to analyse prototype usages in a course (run script /question/type/coderunner/prototypeusagesindex.php)
- Fix crash if user attempts to validate a new prototype question.
Minor updates and bug fixes including:
- Fix broken layout of question authoring form with Boost theme (V3.1.1)
- Fix bugs in PHP and NodeJS question types
- Add Twig STUDENT variable (thanks David Bowes)
- Fix ACE editor gutter showing through Moodle help popups (thanks Tim Hunt)
- Various documentation updates.
Another major refactoring with some significant new features including:
- A 'Precheck' capability, which presents students with an extra button (beside the 'Check' button) that gives a penalty-free submission with limited checking as defined by the question author.
- An answerbox preload capability, allowing the question author to define some initial text to appear in the question answer box.
- Question authors can request that the sample answer be validated whenever a question is saved.
- Simplification of the template mechanism, combining the combinator template and the pre-test template into a single template plus an 'iscombinator' boolean.
- Reworking of the Show differences button, so it's now implemented entirely in JavaScript, removing the complication of having to specify it via the column header.
- Addition of C++ 'write-a-function' and 'write-a-program' question types
- Improved accessibility for visually-impaired students (thanks to Tim Hunt). The tab key now moves focus through all fields in the question-answering form until the student types or clicks in a field. The Ace editor can be switched off with CTRL/M.
- A bulk tester allows administrators and authors to check that all question sample answers pass all tests (copied, with modifications, from the Stack question type).
- The 'Multiple tries' section of the authoring form has been removed and a penalty regime is now mandatory. This eliminates the confusion between the standard Moodle static question penalty (now hidden) and the formerly optional penalty regime. The behaviour of legacy questions is unaffected.
- Add nodejs question type to built-ins.
- Fix bug in regular-expression grader when Expected has trailing new lines.
Minor bug fixes, including:
- Use of Show Differences button with questions containing significant white space output resulted in premature line truncation and/or invalid html output
- Ace editor was not doing syntax highlighting for nodejs questions
- Several panels in question authoring form had monospace labels in Moodle 3.1
Also, the documentation for custom template grading has been rewritten.
A restructured version of the code to conform to Moodle standards. The question behaviour has been deleted from this project, and is now a separate github project moodle-qbehaviour_adaptive_adapted_for_coderunner. The moodle-qtype_coderunner project now contains just the question type code, which has been moved up the file hierarchy to the top level.
Discontinued features:
- The runguard sandbox and the Liu sandbox have both been dropped from this version. Only the Jobe sandbox is officially supported. The ideone sandbox remains as a proof of concept, only. It has never been officially supported.
- Support for upgrading from CodeRunner versions prior to 2.4 has been dropped.
New features:
- Built-in difference-checker to allow students to see how their output differs from the expected output (experimental feature)
- Updated documentation.
Added a feature to display help on the selected CodeRunner question type to the question author in an unfoldable section on the question author form. The displayed help information is the question text from the prototype question that defines the question text.
Also added a feature that allows the author of a question using a template grader to abort the test process, e.g. if a pre-run check on the student's submission failed.
Various bug fixes, most notably to fix broken export of custom question prototypes. Other minor changes and bug fixes include:
- Minor documentation tweaks, e.g. a warning on the perils of duplicating question prototypes and correction to regular expression grader help.
- Fix broken styling of result table with Moodle 2.9 (odd/even row colours weren't happening).
- Improve the error message issued if a prototype fetch fails.
- Fix bug that caused datafiles to get lost when a question was moved to from the special "Default fo quiz" category.
- Improve error message from JobeSandbox e.g. from network failures.
- Fix incompatibility with older (pre 5.4) versions of PHP

- Add some new question types to built-ins and to U of Canterbury set.
- Add some demo questions for new users.
- Fix PostgreSQL incompatibility (thanks Arnaud Trouvé)
- Fix bug in question export when multiple prototypes with the same type name exist in different contexts.
- Added code to support use of an API-key when accessing a jobe server. Fixed bug in advanced question authoring interface - combinator template was no longer being disabled when per-test template was edited.
Refactored code to conform to Moodle style guidelines. Added functionality:
- Files can now be attached to prototypes
- An 'ordering' field associated with each test case allows easy reordering of test cases
- Use of Ace code editor for template editing
- Prompt for disabling combinator template when per-test-case template altered
- Improved ability to pass compile and run parameters to Jobe sandbox
