Share My Creation BasicIDE Suite 4 - Now even further improved

Here we have (yet) another updated version of BasicIDE Suite, my on device development environment.

Basic IDE Suite has three components.


BasicIDE

An on-device development environment which uses the BasicLib B4A library to provide the language interpreter for the IDE. This latest version has a modified editor that provides syntax highlighting and auto-completion for the B4AScript language, the Basic IDE Script extensions and the variable and Sub declarations of the current program. It has error line highlighting together with search and replace. A major addition to the Script extensions are non-modal versions of the original modal user interface dialogs, and the elimination of modal dialogs from Basic IDE itself, apart from the script break and step facility which requires it. There is a discussion of modality and its implications in Basic IDE and its program in a topic in the help file for Basic IDE.

BasicIDE Designer

An on-device visual designer that is used to produce view layouts for use in Basic IDE programs. This version provides both landscape and portrait variants.

BasicIDE Launcher

An app that can quickly run a selected Basic IDE program and whose project can very easily be copied, slightly modified and recompiled by B4A to produce a stand-alone APK of a Basic IDE program that can be installed to a device and run independently as a normal B4A app.


BasicIDE Suite 4 improvements

There are some major improvements over BasicIDE Suite 3 which are as follows

1) Minor UI changes and simplified IME handling internally. InputFile now has colour and text size options.

2) GNSS now returns Galileo information if available. UK National Grid to/from GNSS lat long transformations added.

3) Breaking changes to MessageBox and InputBox (which are deprecated anyway but do work still) to better correspond with the equivalent Async functions.

4) Script module IIF function renamed to IfThenElse owing to a clash when compiling with the IIF keyword added to B4A in v11.0.

6) Script module supports #include to help modularise programs and keep file sizes in the editor down. Subs only, no global definitions in included files but equivalent persistent values available by two new functions SaveValue(valuename, value) and RestoreValue(valuename) As returnvalue.

7) The BasicIDE editor now supports 'flinging'. I'm pleased with this. It was an obvious missing feature that I tried and failed to add before because I couldn't see the wood for the trees. Thanks JesseW!

8) The size of the Autocomplete popup window is now a user variable option.

9) The BasicIDE editor now persists the values for the AutocompleteMode, AutocompleteHeight, AutocompleteThreshold, Font, FontSize, SmallFontSize and IndentSize menu options

10) Both BasicIDE and BasicIDE Designer support projects to enable the isolation of groups of related program files.

11) All the help files in the Files folder may be updated after changing the .chm help files or the Script module by running a new program, UpdateHelp.exe. BasicIDE detects when these have changed and copies them from DirAssets to the device BasicIDE Help folder when required.


Important

Read the downloaded Readme file and the Overview section of BasicIDE.chm or BasicIDE.html for both device and desktop installation instructions to achieve the correct project folder structure. These files are located in the BasicIDEHelp zip file.

Before extracting the BasicIDEHelp zip file it should be unblocked by right clicking on it in File Explorer, selecting Properties and checking Unblock at the lower right of the General tab. In particular this allows the .chm help files to be properly displayed by Windows and allows UpdateHelp.exe to run without a security warning. If the .chm files are not unblocked their content will not be available in the Windows help viewer. The files may be individually unlocked later if this step is omitted.


Minor Bug

The bug symptom is that the autocomplete popup window appears as a single line located at the top of the editor rather than being located perched on top of the IME. See Post #2 below for the explanation and fix.


Updates

BasicIDE version 6.00 posted in BasicIDE_v6.00.zip together with updated help in Help_6.00.zip. See post #5 for details

I have found a minor bug that I overlooked when adding the fling capability to the editor. It only occurs on one of my five testing devices, a Galaxy Tab A 8, which is why I have only just found it. The bug symptom is that the autocomplete popup window appears as a single line located at the top of the editor rather than being located perched on top of the IME. This is because in the IME HeightChanged event I overlooked changing the position of the popup from the edtSource height to the svFling height. The new code should look as below.
B4X:
Sub IME_HeightChanged (NewHeight As Int, OldHeight As Int)
  ...      
  ' this will sit the dropdown above the IME
  'edtSource.AutoVerticalOffset = edtSource.Height  -  Commented out old line
  edtSource.AutoVerticalOffset = svFling.Height ' new corrected setting
  ...
End Sub
It's odd that most devices don't need this but I guess there is something a bit different in the Samsung but as it's the only Samsung device I have I don't know if it just a quirk of that particular model.

It uses my CodeEditorView control which is a wrap of this project

which in turn is a thin veneer on top of
android.widget.MultiAutoCompleteTextView;

It's keyword tokeniser was a bit limited so I rewrote it but its only a few lines of code. I haven't posted it as a library but the XML should be reasonably well commented to use elsewhere if required. The jar and xml are in the BasicIDELIbraries zip file. You are welcome to my source codes if you did want a play with it.

In adding KVS to BasicIDE to persist some IDE values I overlooked the case for a fresh install without installing over a previous install that already has file permissions. Because of the way that Resumable Subs work waiting for the permission causes both Activity_Resume to run as the wait returns from Activity_Create and then Activity_Pause runs as the permission dialog is shown. As Resume tries to read the KVS values and Pause tries to save them the lack of file permissions causes errors that prevent operation of the BasicIDE. This is now fixed. I'm surprised that apparently none of the down-loaders have encountered this as it is a show stopper for new installs.

A continual problem with BasicIDE over the years has been the poor API to the IME and inexplicable variations in behaviour between different device and soft keyboard combinations when an Activity is paused and resumed with the keyboard open. I have finally thrown in the towel and locked the editor into portrait orientation, though scripts can still support device rotation if required. This allows predictable behaviour on Resume. There are further comments in the Main activity code in the version history and the IME_HeightChanged event.

The Autocomplete Height menu option now has an Auto option that will auto-size the popup window to accommodate the available options, and is scrollable if the number of options exceeds the maximum height available for the popup window.

Upon loading the project, I have an "unknown member: textsize" error on line 5952, shown as line 6 below, in the Script module
B4X:
Sub AsyncInputFile(filepath As String, filename As String, filefilter As String, title As String, Positive As String, Cancel As String, Negative As String, _
            cancellable As String, callback As String, paramsarrayname As String)
    Dim params() As String = BlibGetAsyncArray(paramsarrayname)
    Dim F As FileDialog
    F.TextColor = InputFileColor
    If InputFileTextSize > 0 Then F.TextSize = InputFileTextSize
    F.filepath = filepath
    F.ChosenName = filename
    F.filefilter = filefilter
    Try
        Dim o As Object = F.ShowAsync(title, Positive, Cancel, Negative, Null, cancellable)
        Wait For (o) Dialog_Result(response As Int)   
        input = F.filepath & "," & F.ChosenName
        params(0) = response
    Catch
        params(0) = DialogResponse_Cancel
        input = LastException.Message       
    End Try
    If Blib.CanCall(callback) Then
        Blib.Call(callback, params)
    End If
End Sub

Looks like you have an out of date Dialogs2 library
