Keera Hails: Haskell on Rails - Reactive Programming Framework for Interactive Haskell applications

keera-hails's Issues

File name overlap hlint.hs/HLint.hs

Multiple packages in this repo contain an hlint.hs and an HLint.hs under tests/.

The difference between uppercase and lowercase names is frequent on linux, but not on mac or windows. This would make it very hard to use these projects on those architectures, and would confuse cabal and git.

These files should be named differently. The cabal file needs to be adapted accordingly.

Not in scope: type constructor or class ‘PlugClass’

Trying to compile haskell-titan on MacOSX with GHC 8.6, I get the following error:

Elementary Gtk Demo fails to compile with GHC 8.6

The demo included with hails fails to compile to it the accompanying package having a low version bound for base.

Should keera-hails-mvc-model-lightmodel depend on gtk?

It only depends on Gtk very indirectly. It will never invoke Gtk code.

Use Name in place of String in Hails.MVC.Model.THFields.protectedField

The function that generates an RV for a field of a record takes string arguments. It might make more sense to use Name arguments, but then it would be necessary to change the programs that use it.

See mvc-model-protectedmodel/Hails.MVC.Model.THFields.protectedField.

keera-hails initialization program does not work by default

The keera-hails initialization program, which is supposed to be used to create a new app from scratch, is not working. The resulting files include imports that do not exist in any keera-hails-* library at the moment.

Further cleaning of keera-hails-reactivevalues cabal file

The cabal file in this directory is not fully compliant with our current policy: the version bounds are not separated by a space in cabal-version, and the unit test suite is just not formatted.

keera-hails-i18n: documentation: package

The package documentation is missing, which does not let people know how to use the package or what it does.

https://hackage.haskell.org/package/keera-hails-i18n

The API is poorly documented and it's not intuitive enough to help people understand what this does or how to use it, so they cannot figure it out by themselves.

Seamless combination of RVs and Rules with ReaderT r IO

The following construction is very common:

installRule cenv = do
  f <- someFieldOfAnUIElement <$> someUIElement (uiBuilder (view cenv))
  let f2 - someFieldOfTheModel (model cenv))

 f =:= f2

The cenv is being passed around. Ideally, we'd want to write:

installRule =
  (someFieldOfAnUIElement . someUIElement) =:= someFieldOfTheModel

An initial approximation would be possible if we make RVs and RRs run on a reader monad with cenv in the environment. Some additional modifications would be necessary to make model and uiBuilder.view somehow implicit, and to make the (<$>) go away.

Make all README files markdown

Markdown renders nicer on github.

We could use the same format and structure for all packages.

Update maintaner email address

The maintainer's address is old and still points to ivan's address. This should just be [email protected].

keera-hails-mvc-environment-gtk: remove sources.txt

Files named sources.txt are related to an old build tool that is no longer used in Haskell and no longer serve any purpose.

Is the .hackage file necessary?

There is a .hackage file in the repo.

I do not find any evidence that this file is being used anywhere.

Should it be removed?

Upload a new version of keera-hails-reactive-gtk to Hackage

The problem pointed out in #8 has been corrected by commit bd7019f. But, the fixed library has not been uploaded to Hackage (last upload was in 2015), meaning the Hackage version still does not compile with the current version of the gtk library (0.15.2).

It would be nice if a new version was uploaded that contained the fix :)

Improve documentation in Data.ReactiveValue

I find the structure of the module and the documentation unhelpful. I think it could be improved, initially with more examples and by moving elements within the module.

Copy basic demo into demos folder

It would be useful to have the trivial demo just added to the library in e22c0bf#diff-f247725f39b33ecfb58291261d453171 copied also as a separate example in the demos/ folder, with its own cabal file, and potentially installed in travis (but not deployed to hackage).

This would make it easier for people to start with Hails, and would ensure that everything keeps working.

Improve support for GTK3

Support for GTK3 right now is lacking. We cannot create complex applications with GTK3 wtihout a lot of boilerplate.

Because this is already done in GTK2, it should be trivial to port to GTK3.

Review licenses and copyright notices

Everything produced at/for/by Keera has copyright Keera Studios. All software, talks, pages, papers, public or private, released or under development, need to have clear copyright and usage licenses.

Repo contains useless .hgignore

This repo contains an .hgignore file which does not belong as we are using git.

My guess is that this was once a mercurial repository and that was never seen or removed.

Failure to compile due to missing dependency

We are getting this on travis:

Improve the story regarding dialogs

Certain reactive constructs like dialogs do not yet integrate well with RVs.

An example, from https://github.com/keera-studios/haskell-titan/blob/develop/titan-gui/src/Controller/Conditions/Buttons.hs#L89, is:

installConditionLoadTrace cenv = void $ do
  btn <- toolButtonActivateField <$> toolBtnLoadTrace (uiBuilder (view cenv))
  btn =:> conditionVMLoadTrace cenv

conditionVMLoadTrace :: CEnv -> IO ()
conditionVMLoadTrace cenv = do
  window <- mainWindow (uiBuilder (view cenv))
  fch <- fileChooserDialogNew (Just "Open Yampa trace") Nothing
                              FileChooserActionOpen
                              [("Cancel", ResponseCancel),
                               ("Load", ResponseAccept)]

  ytrfilt <- fileFilterNew
  fileFilterAddPattern ytrfilt "*.ytr"
  fileFilterSetName ytrfilt "Yampa Trace"
  fileChooserAddFilter fch ytrfilt

  nofilt <- fileFilterNew
  fileFilterAddPattern nofilt "*.*"
  fileFilterSetName nofilt "All Files"
  fileChooserAddFilter fch nofilt

  widgetShow fch
  response <- dialogRun fch
  fp <- case response of
          ResponseCancel -> putStrLn "You cancelled..." >> return Nothing
          ResponseAccept -> do nwf <- fileChooserGetFilename fch
                               case nwf of
                                 Nothing   -> putStrLn "Nothing" >> return Nothing
                                 Just path -> putStrLn ("New file path is:\n" ++ path) >> return (Just path)
          ResponseDeleteEvent -> putStrLn "You closed the dialog window..." >> return Nothing

  widgetDestroy fch
  awhen fp $ \p -> do
    contents <- readFile p
    sendToYampaSocketAsync (extra cenv) (show (LoadTraceFromString contents))

Instead, one could think of this dialog as a sort-of fudget or reactive processor. If synced, it could be described with something like:

(toolButtonActivateField . toolBtnLoadTrace) =>= openFileDialog =>= loadFile  =:> sendNewTrace

Include sample application built with keera-hails

One of the packages provided by this library is keera-hails, which lets users build sample applications. This package is not documented, so it is unlikely that any users have been able to use it as is.

A minimal readme would help newcomers see an app running on the screen with very little effort.

Subissue of #7 .

keera-hails and keera-hails-templates are near duplicates

These two executables are near duplicates. It does not seem to make sense to have two of the same.

I suggest that keera-hails-templates be removed.

Release new version of hails-network

The package keera-hails-reactive-network has an upgrade that needs to be made available on hackage.

A new version must be released.

gtk2 function notebookGetCurrentPagePassive

The notebookGetCurrentPagePassive function returns -1 in my program.

Create a new notebook n
n <- notebookNew
Define notebookGetCurrentPagePassive as the getter of curPageRV
let curPageRV = ReactiveFieldReadWrite setter getter notifier where (ReactiveFieldRead getter _) = notebookGetCurrentPagePassive n setter = postGUIAsync . notebookSetCurrentPage n notifier io = void $ afterSwitchPage n (const io)
When the current page is deleted and reactiveValueRead curPageRV is called, sometimes it will return -1.
reactiveValueRead curPageRV >>= print
When the current page is deleted, will notebookGetCurrentPagePassive always return -1? How does this function show the passive effect?

The reactive programming library dunai can be used to run reactive applications.

Hails applications could connect to those dunai applications by turning the former into MSFs, or the latter into RVs.

We need examples of this.

Improve README

The readme should include examples of how reactive values can be created, manipulated, and connected, including how to create connections to Gtk/Wx/HTML or maybe Yampa stuff.

keera-hails-mvc-controller: documentation: package

The package documentation is missing, which does not let people know how to use the package or what it does.

http://hackage.haskell.org/package/keera-hails-mvc-controller

The API is poorly documented and it's not intuitive enough to help people understand what this does or how to use it, so they cannot figure it out by themselves.

Cleaning cabal files

This project is hard to maintain due to being formed of many smaller packages.

We want to make the cabal packages as uniform as possible.

keera-hails-mvc-model-lightmodel: build on hackage failed

The build on hackage failed with the following message:

src/Hails/MVC/Model/ProtectedModel/Reactive.hs:66:50:
Expecting one more argument to ‘ReactiveFieldReadWrite a’
Expected a type, but ‘ReactiveFieldReadWrite a’ has kind ‘* -> *’
In the type ‘ProtectedModel b c -> ReactiveFieldReadWrite a’
In the type declaration for ‘FieldAccessor’

Update versions of GHC on travis

Currently, hails is failing to compile on Travis due togtk2hs-buildtools not building with GHC 8.0. Additionally it is not trying to compile with modern versions of GHC.

keera-hails contains unused files

The library keera-hails contains unused files in src/.

Many of those files appear to exist in other libraries, so I do not understand why they are included in keera-hails. I think they should be removed.
