This repository contains the iTask framework for developing Task-Oriented Programs # What is iTasks ? The iTask framework enables you to write multi-user web applications using a task-oriented style of programming. Applications range from simple web applications for filling out web-forms, to large workflow support systems. Essentially any application to support people in an organization to work together using the internet. Applications are defined on a high level of abstraction, called "Task Oriented Programming" (TOP). In this new style of programming, one defines the tasks humans and machines have to do. One can abstract from low level technical stuff, like the communication between browsers and the server, the generation and handling of user interfaces, the storage of information on disk or in databases. TOP can be seen as an Embedded Domain Specific language, realized with a Combinator Library programmed in the host language Clean. ## Set up ### Step 1: Clean and dependencies To use the framework you need to have a recent install of the Clean language. The easiest way to obtain this is to get the `clean-bundle-itasks` nightly build package. This contains everything you need to get started. This bundle can be downloaded from: [ftp://ftp.cs.ru.nl/pub/Clean/builds/&lt;OS version&gt;/clean-bundle-itasks-&lt;OS version&gt;-latest.[zip|tgz]](ftp://ftp.cs.ru.nl/pub/Clean/builds/<OS version>/clean-bundle-itasks-linux-64-latest.tgz) Alternatively you can also download a `clean-base` package from the same ftp-site and add the following packages `clean-lib-generics` `clean-lib-dynamics` `clean-lib-platform` `clean-lib-sapl` `clean-lib-graphcopy` and `clean-lib-tcpip`. ### Step 2: Configuring CleanIDE or Cpm Given that you are reading this README file, you have probably cloned this repository directly from: https://gitlab.com/clean-and-itasks/itasks-sdk If you also have a packaged version of iTasks installed in your `$CLEAN_HOME/Libraries` folder (e.g. the one from the `clean-bundle-itasks`) repository you need to make sure that you are using the checked out version instead of the bundled version. You can put your checkout everywhere you like, but to get started quickly we provide a convenient `iTasks git` environment for use with the CleanIDE/Cpm. You can find this environment in `Config/<OS version>/iTasks-git.env`. This environment expects your git checkout to be located in `$CLEAN_HOME/Development/iTasks-SDK`. ## Organisation of this repository This repository follows the structure of a Clean system install. The top-level folders are: - `Libraries` : Here you find the iTask framework Clean library. - `Tools`: These contain additional tools you need to create iTask applications. Currently there is only one tool you really need: the web resource collector. This program is essentially a linker, but for static web resources such as images, html/css and javascript files. In the `Libraries` folder exist special `WebPublic` folders with these resources. At compile time, they are collected based on which parts of the framework is used by your application. - `Examples`: In this folder you can find example programs that demonstrate the iTask framework. - `Tests`: In this folder you can find test programs that are used to automatically and interactively test the framework - `Config`: Here you can find the environment definitions for the CleanIDE/Cpm. These are organized in subfolders for each OS/Platform because paths are different on each target. - `Documentation`: Here you can find supplemental documentation. A good starting point is the iTask guide (`Documentation/GUIDE.md`). ## Basic API Examples The most basic examples that give an overview of the iTasks framework can be found in the module `BasicAPIExamples` in the directory `Examples`. You can generate the source code for this project by running: ```bash cp CreateBasicAPIExamples.prj{.default,} cpm CreateBasicAPIExamples.prj ./CreateBasicAPIExamples.exe > BasicAPIExamples.icl ``` To compile the project you can then use: ```bash cp BasicAPIExamples.prj{.default,} cpm BasicAPIExamples.prj ``` This creates `BasicAPIExamples.exe`. Despite the extension this executable works on your current platform. The implementation of the various example tasks can be found in the `Examples/BasicAPIExamples` directory. There you also find project files that you can use to test examples in isolation. Be aware that by default `BasicAPIExamples.prj` will use the iTasks sources from the Clean installation, not from this repository. You need to change the target environment or the paths to build using the sources in this repository.

Project have to use `cocl` instead of `cocl-itasks` as compiler from now on. - Change: uniqueness attribute of `Editor`/`LeafEditor` has changes. Extensions defining custom editors may need adaption. #### 0.13.9 - Fix: place 'Date' header before first part of multipart mails. #### 0.13.8 - Feature: add `==`, `gPrint` and Gast instances for `iTasks.Extensions.Email.Attachment`. - Fix: `gEditor` implementation for `Bool` when used with e.g. `enterInformation`; use `False` as initial value if the editor is non-optional. #### 0.13.7 - Feature: add `iTask` instances for `Extensions.Email.Attachment`. - Fix: bug in choiceEditor causing it to break when editing a value using a choice editor. - Fix: error handling in tcp handlers. - Fix: issues with sending mails with attachments. #### 0.13.6 - Fix: `sendEmail` did not work. #### 0.13.5 - Feature: add `choiceEditorWithCustomLabels`, `multipleChoiceEditor` and `multipleChoiceEditorWithCustomLabels`. #### 0.13.4 - Fix: definition of `group6`, `buttonbar6` and `buttonbar7`. #### 0.13.3 - Chore: support gPrint `^3`. #### 0.13.2 - Feature: add date header to emails sent using `sendEmail`. #### 0.13.1 - Chore: adapt based on `MaybeError` now being located in `Data.Error.GenJSON`. - Chore: adapt based on `Map` now being located in `Data.Map.GenJSON`. - Chore: adapt based on `Set` now being located in `Data.Set.GenJSON`. ## 0.13 - Removed: JSON derives of `MaybeError`, `Set` and `Map` (they are now derived in `Text.GenJSON` instead). - Chore: allow generic-print 2 alongside generic-print 1. ## 0.12 - Chore: support base `v2.0`. - Change: removed several extensions, they will be published separately. #### 0.11.3 - Fix: use the correct instance number in `attach` and `appendTask`. #### 0.11.2 - Fix: do not delete the IO State when the connection is closed due to an `onShareChange`. - Fix: gather values for the task result of `tcplisten` before deleting the IO states when the task is destroyed. #### 0.11.1 - Fix: enabled/visible attributes not being taken into account when using `withExtraAttributes`. - Fix: fix CSS syntax error in default style. - Enhancement: use style colors for dropdown controls. ## 0.11.0 - Change: Change some I/O handlers to return a `?l` instead of an `l`. This info can be used to determine whether or not to send a refresh. - Change: rename `createReadOnlySDSError` to `createReadOnlySDS` and remove the original `createReadOnlySDSError` function, Add a parameter which indicates if read operations on such an SDS should be cached. - Feature: add `constShareNamed` for making a const share with a provided SDS identity. - Fix: Prevent crashes when using `select2Dropdown`. - Fix: Call `afterRender` of client components after their DOM element is inserted. - Enhancement: The `TaskId` in `IOState` is now optional. If it is `?None`, no refresh event is sent. - Enhancement: reorganise the `TaskEvalInfo`, `TaskEvalState` and `TaskEvalOpts` types so that they contains fields that are suitable (e.g. `TaskEvalOpts` now only contains read-only fields). - Enhancement: use brighter colors in the default color scheme. ### 0.10.2 - Fix: `addConnection` now stores the connectionId immediately in the handlemap to avoid `` onError` `` being called while there is no ioHandle available in said map. ### 0.10.1 - Chore: Update graph-copy dependency ## 0.10.0 - Change (Fix): Redo I/O layer between iTasks and AsyncIO - Connections are now indexed by a unique `IOHandle` instead of by `ConnectionId`. that is guaranteed to be unique. - I/O state is simplified in IWorld (see [Documentation/Design/IO.md](Documentation/Design/IO.md)) - `addConnection` now only returns an `IOHandle` (the initial value wasn't used anyway). - Move some functionality that required AsyncIO functions from `iTasks.Internal.TaskServer` to `iTasks.Internal.AsyncIO`: `processOnShareChangeOnDestroy` and `emptyAsyncIOWriteQueues`. - Change: `readRegister` now receives a `TaskContext` as well as a `TaskId`. - Change: Async SDS interface is made safer (fixed some types) and more localised (IO is occuring now in the instance instead of via a chain of helper functions). - Change: `evalTaskInstance` now does not return the last task value (was not used anyway and very often wrong [e.g. On a destroy, it yielded NoValue]) - Enhancement: `connect` that handles the initial listeners of the engine now uses `addListener` instead of copying its behaviour locally. - Enhancement: `processOnShareChangeOnDestroy` in the engine now skips calling many handlers for certain I/O states. - Feature: Add debugging functions to `iTasks.Internal.Util` to trace the `IOStates` and print `Dynamic` values. - Enhancement: Make the async task test more robust by letting it stop itself if some time is reached and trace the status. ### 0.9.1 - Feature: UserAdmin extension: add `activeTokens` lens which given a set of authentication tokens (through the SDS parameter), returns the authentication tokens that are currently active as a read value. ### 0.9.0 - Change the SDS semantics. `modifySDS` now returns an auxiliary value and can write to the SDS. User-facing, the following functions have been added: `access`, the task to read, possibly write and produce an auxiliary result an SDS. Internally, the following functions have been added/changed: `amend`, the internal function to read, possibly write, and produce an auxiliary result an SDS. `modifySDS`, now includes an auxiliary result and makes writing optional. - Adapt `SDSSource` so that it includes an amend function as well, allowing you to create SDSs that atomically update and yield a value (see `Examples/AtomicInsertSQLite.icl`) ### 0.8.12 - Export `register` and `checkRequests` functions from iTasks.Internal.SDS. These are required for implementing your own SDS types (i.e. datatypes that implement the Readable, Writeable, etc. classes). ### 0.8.11 - Feature: add `iTasks.Extensions.CSVFile.createExcelCompatibleCsvFile`. ### 0.8.10 - Enhancement: add error information if iTasks unit test crashed when applying events/failing to create the `IWorld`. ### 0.8.9 - Feature: add `UI.Editor.Containers.group6`/`group7` and variants. - Chore: allow `abc-interpreter` version `^1.2.2`, which fixes the issue of the previous version. ### 0.8.8 - Fix: HTTP server closing connection directly if being idle for longer than the keep-alive time. ### 0.8.7 - Fix: set abc-interpreter dependency to 1.2.0. ### 0.8.6 (BROKEN) - Fix: prevent infinite stream of generated events when destroying sessions tasks to which was never attached, i.e. the first event the task was evaluated with was a `DestroyedEvent`. - Chore: update node dependencies. ### 0.8.5 - Enhancement: remove redundant `onRefresh` queue from `tcpconnect` task. ### 0.8.4 - Fix: `WF.Tasks.IO`: adapt externalProcess for a bug causing an external process to have `NoValue` after the process had terminated. ### 0.8.3 - Chore: adapt iTasks to use AsyncIO package. ### 0.8.2 - Feature: add the `afterRender` event to iTasks components, which is required for JavaScript code run after the children of a component are rendered. ### 0.8.1 - Enhancement: the list `specialkeys` in `iTasks.Extensions.SVG.SVGEditor` extended to cover the special keys; This is relevant for the `OnKeyDownAttr` attribute function of `Graphics.Scalable` (clean-platform) ## 0.8.0 - Change: replace `withClientSideInit` and `withClientSideInitOnLeafEditor` with a type `JavaScriptInitFunction` and corresponding `tune` instances, in a new module `iTasks.UI.JavaScript`. - Change: Providing `Int` for the port number of the tcpconnect/tcplisten task has been replaced for a `Port` newtype. - Change: The `onData` and `onDisconnect` callbacks of the `tcplisten`/`tcpconnect` tasks now accept a connection identifier as it's first argument. - Removed: `serializeForClient` from `iTasks.Internal.Serialization`; use `jsDeserializeGraph` instead. - Feature: make it possible to tune tasks with client-side initialization code. - Feature: add `Collapsible` which can make panels collapsible by clicking on their header. - Enhancement: add `TitleIcon` to be able to add icons to titles. These are added to the left of panel and window headers in the default layout, but ignored in tab buttons. - Enhancement: add `SecondaryTitle` and `SecondaryTitleIcon`, which are like `Title` and `TitleIcon` but of secondary importance. The default aligns these on the right in panel and window headers, and ignores them in tab buttons. - Enhancement: Use System.AsyncIO for network I/O. This means that the `select` mechanism of the underlying event loop has been replaced for epoll (Linux)/IOCP (Windows) and network I/O is provided through these mechanisms instead. ### 0.7.3 - Fix: make sure `externalProcess` task closes pipes. ### 0.7.2 - Feature: added support for handling keyboard events & controlling keyboard focus to SVGEditor. ### 0.7.1 - Feature: enable ABC interpreter GC on idle by default and add option to disable it. - Fix: Update `WF.Tasks.IO`, fix bug in `externalProcess` causing pipes to not be closed. ## 0.7.0 - Change: adapt `sdsSequence` such that it is only required to specify the parameter for the right SDS if we actually perform a read or write operation on that SDS. - Feature: provide `genShow`, `gPrint` and `gHash` instance for `DynamicEditorValue`. - Enhancement: remove superfluous `gHash` constraints from SDS related functions. ### 0.6.2 - Fix: add scrollbar to `ChooseFromGrid` selection tasks in some environments where it did not appear. - Fix: Add overflow-y: scroll to `itasks-scroll-content` class to make sure a vertical scroll bar is added when the content does not fit height-wise. ### 0.6.1 - Feature: add `DisableIoRedirectionToShares` option to `ProcessOption` to disable redirection of stdout/stderr when using external process tasks. - Chore: remove leaflet related packages from package.json. ## 0.6.0 - Change: Removed the iTasks leaflet extension from the SDK repository. It is now located in the iTasks-leaflet repository (https://gitlab.com/clean-and-itasks/itasks-leaflet). The leaflet extension is now published as a nitrile package named "itasks-leaflet". The `iTasks.Extensions.GIS.Leaflet` module has been renamed to `iTasks.Leaflet`. The `iTasks.Extensions.GIS.LeafletNavalIcons` module has been renamed to `iTasks.LeafletNavalIcons`. ### 0.5.10 - Fix: Make tasks in `iTasks.Extensions.JavaScript` yield stable results. ### 0.5.9 - Feature: Update the user admin extension to allow specifying a custom data source for storing user accounts. ### 0.5.8 - Fix: Leaflet "on map click" events on mobile devices. ### 0.5.7 - Chore: Make leaflet map functions strict and add type annotations - Enhancement: Use CSS variable for color of leaflet tooltip instead of always coloring it orange. The default color matches the color of the itasks tooltip. ### 0.5.6 - Enhancement: Add `instance ==` and `instance <` for `URL`. ### 0.5.5 - Enhancement: Adapt leaflet-window CSS to be consistent with the style of iTasks windows. ### 0.5.4 - Enhancement: iTasks.UI.Layout: add `selectActionsWithName UISelection helper function. ### 0.5.3 - Fix: check if the enabled attribute of input component is null on the client, which may happen if the attribute is deleted on the server. ### 0.5.2 - Fix: enabledAttr UIAttribute is now taken into account for html input elements. ### 0.5.1 - Enhancement: Change html representation of dynamic editor lists based on changes to the editor for such lists. ## 0.5.0 - Change: Adapt API for `SDSLensNotify` type to allow to specify that a `SDSLens` should never or always be notified when the child of the `SDSLens` is notified. to avoid filtering notification registrations when it is not necessary to do so and avoid registering the SDSLens itself. ### 0.4.1 - Enhancement: cache values read from SDS source during a single task evaluation to improve performance and provide a consistent view. ## 0.4.0 - Change: Adapt API for `WF.Tasks.IO.externalProcess` `Extensions.Process.callProcess` and `Extensions.Process.callProcessAndCheckReturnCode`. Allows providing a custom exit code/signal for terminating the external process when the task is destroyed for `callProcess` and `callProcessAndCheckReturnCode`. ### 0.3.1 - Fix: `workOnChosenTaskWithSharedChoice` no longer hides tasks which should be displayed when used in a nested manner. ## 0.3.0 - Fix: Make write type of `htmlViewWithCustomEditEvents` return an optional write value. `htmlViewWithCustomEditEvents` would break when used within a composition of editors. ### 0.2.12 - Feature: Add `htmlViewWithCustomEditEvents` editor alongside `toHtmlEventCall` function. This provides an interface for sending edit events to the server based on interacting with the HTML that is being shown using the editor (E.g clicking a HTML button). ### 0.2.11 - Enhancement: Leaflet extension: remove workaround which is not required anymore. ### 0.2.10 - Chore: Update Leaflet and pixi.js libraries to include various bugfixes. ### 0.2.9 - Fix: Leaflet extension: prevent warnings about listeners of type `undefined` and possible follow-up issues. - Fix: Leaflet extension: update marker connectors when collapsing Leaflet windows. - Fix: Leaflet extension: prevent tooltips not being removed when corresponding marker is. ### 0.2.8 - Feature: add `gEq` instance of `EditorReport`. ### 0.2.7 - Feature: add `callProcessAndCheckReturnCode` checking for return code of called processes. ### 0.2.6 - Chore: update pixi, including some bugfixes. ### 0.2.5 - Fix: `workOnChosenTask` altering attributes of `:: LeafEditor` which affect size do no longer lead to map being drawn incorrectly. ### 0.2.4 - Chore: update `ace-builds` and `moment`. ### 0.2.3 - Fix: use ellipsis truncation for leaflet window titles, fixing a bug where windows couldn't be closed when the title was too long. ### 0.2.2 - Feature: package the itasks selenium driver. ### 0.2.1 - Chore: upgrade base-compiler-itasks version constraint from =1.0.0 to ^1.0.0 || ^2.0.0. ## 0.2.0 - Fix: a list editor without values is valid again. - Feature: add `maybeToEditorReport :: !(?a) -> EditorReport a`. - Fix: improve generic `Bool` editor: when the value is required, do not show a dropdown with a `Select...` option but use a checkbox. - Switch to nitrile package manager using semantic versioning. ## 22.5 No changes. ## 22.4 No changes. ## 22.3 ### New features - `Extensions.Editors.DynamicEditor`: Added functionConsDynWithPredOnChildConses :: !DynamicConsId !String !(Int DynamicConsId -> Bool) !Dynamic -> DynamicCons, Gijs Alberts (gijs@gijsalberts.nl), !683 - `UI.Editor.Controls`: Added `textFieldNoValueByDefault :: Editor String (EditorReport String)`, Gijs Alberts (gijs@gijsalberts.nl), !686 - Re-added Leaflet options to hide/show the attribution/zoom control, Steffen Michels (@smichels), !690 ### Bug fixes - `iTasks.Extensions.Admin.UserAdmin`: It's no longer possible to change username of existing users, since this leads to unexpected behavior, Elroy Jumpertz (@ElroyTop), !691 - Strings provided through `Label`, such as `Label "This Is My Text"` are generated as-is, instead of changing the capitalization to `This is my text`, Elroy Jumpertz (@ElroyTop) !694 ## 22.2 ### New features - Upgraded Leaflet. Improved performance using Pixi. Deleted (unused) fields in Leaflet's `MapOptions` - `attributionControl`, `zoomControl`, `editable`. New fields in Leaflet's `MapOptions` - `viewMousePosition`, `viewMeasureDistance`, `viewLegend`. New fields in Leaflet's `LeafletMarker` - `rotation`, `tint`. Changes in Leaflet's `LeafletMarker` - `title` is now of type `?HtmlTag`. Additional dependencies added, which are managed through npm. Elroy Jumpertz (@ElroyTop), !677 - Added `choiceEditor` to `UI.Editor.Common`, Elroy Jumpertz (@ElroyTop), !680 ## 22.1 ### New features - Added `listConsDynWithOptions :: !Bool !Bool !DynamicConsId !String !Dynamic -> DynamicCons` to `Extensions.Editors.DynamicEditor` which allows to specify whether dynamic editor list elements may be removed or reordered, Gijs Alberts (gijs@gijsalberts.nl), !658 - Added `gDefault` instance for `:: EmailAddress` to `Extensions.EmailAddress`, Gijs Alberts (gijs@gijsalberts.nl), !661 - Added waitForTimerNSec, Gijs Alberts (gijs@gijsalberts.nl), !667 - Added `defaultEngineCLIOptionsWithExtraOpts :: [OptDescr ((?EngineOptions) -> ?EngineOptions)] a [String] EngineOptions -> MaybeError [String] (a, EngineOptions)` to allow specifying custom command line parameters to iTasks programs in a convenient manner, Gijs Alberts (gijs@gijsalberts.nl), !668 - iTasks.Extensions.DateTime: added `waitForUtcDate :: !Bool !Date -> Task Date` which waits for a date based on UTC time, Gijs Alberts (gijs@gijsalberts.nl), !671 ### API changes - 32-bit support is removed; from now on iTasks supports 64-bit platforms only, Steffen Michels (@smichels), !669 ## 22.0 ### New features - Added `dynamicEditorValueContainsConsId :: !(DynamicEditorValue a) !DynamicConsId -> Bool` which returns whether a dynamic editor value contains the specified contructor id to `iTasks.Extensions.Editors.DynamicEditor`, Gijs Alberts (gijs@gijsalberts.nl), !653 ## 21.7 ### New features - `iTasks.Testing.Selenium.Interface`: export `expectCSSValue` function, Gijs Alberts (gijs@gijsalberts.nl), !635 - Added `Eastwood.yml` for Clean language server support for the entire iTasks codebase, Elroy Jumpertz (@elroyTop), !639 ### API changes - `iTasks.UI.Layout.Common`: change type of `arrangeAsMenu` from `:: [[Int]] -> LayoutRule` to `:: ![!Menu] -> LayoutRule`, Gijs Alberts (gijs@gijsalberts.nl), !635 ### Bug fixes - fix directory WebResourceCollector places the web content in; this was not consistent with the task server engine for executables with extensions different from .exe, Steffen Michels (@smichels), !645 - fix behaviour of textField/passwordField when entering information with minlength = 0 & fix documentation, Steffen Michels (@smichels), !646 ### Other - 32-bit platforms are not actively supported anymore, Steffen Michels (@smichels), !634 - Tests are now all compiled in the CI pipeline, with some exceptions, Elroy Jumpertz (@elroyTop), !644 ## 21.6 ### New features - A user can no longer delete himself using `manageUsers`, Elroy Jumpertz (@elroyTop), !624 - Export `==` instance for `:: EmailAddress`, Gijs Alberts (gijs@gijsalberts.nl), !629 - Export `rolesEditor` in `UserAdmin.dcl`, Gijs Alberts (gijs@gijsalberts.nl), !630 - Export `userRoles` in `WorkflowAdmin` module, Gijs Alberts (gijs@gijsalberts.nl), !631 ### Fixed bugs - Fixed issue where `currentTaskInstanceCookies` aborts in very rare cases due to no matching pattern, leading to a server crash, Elroy Jumpertz (@elroyTop), !623 - Prevent 100% CPU load by sleeping or shutting down when there are no `IOTask` instances, Elroy Jumpertz (@elroyTop), !626 - Fixed internal exception in `UILoader`, Camil Staps (info@camilstaps.nl), !628 ## 21.5 ### New features - Introduced a distinction between invalid and empty editors. For this editors have been changed in two ways: 1. changed the editor to accept optional values in `onRefresh`, just as in `onReset` enabling a soft-reset. 2. changed the top-level write type of editors used in tasks to a three valued ADT to indicate valid/invalid/empty This eliminates several problems with using optional values in editors and setting useful hint and error messages. Bas Lijnse (@baslijns), !549 - Changed default generic editor for booleans from checkbox to dropdown, Bas Lijnse (@baslijns), !609 ## 21.4 ### New features - Added frontend setting `itasks.settings.error_handler` to customize frontend error reporting (see `WebPublic/index.html`), Camil Staps (info@camilstaps.nl), !601 - Minor additions to Selenium interface: `TabKey`; `getFocusedElement`; `focusElement`; `elementsAreEqual`, Camil Staps (info@camilstaps.nl), !603 ## 21.3 ### New features - The frontend function `doEditEvent` now has an alternative with only a value argument.
