Android Tutorial [B4X] Comment Links

New feature added in B4A v10.0, B4J v8.50 and B4i v6.80. It will also be added to B4R.

Code comments can include clickable links. The following schemes are supported:

http(s):// - Link will be opened with the browser.
Example:

Dim key As String = OrderedMap.Keys.Get(0) 'based on https://www.b4x.com/android/forum/threads/b4x-b4xorderedmap-get-first-item-nth-item-and-last-item.118642/

file:// - Link will be opened with the default program.

'see the presentation: file://C:\Users\H\Documents\Presentation+With+Spaces.pptx

ide:// - Link will be handled by the IDE. There are currently two types of methods:
goto:
Clicking on link will move the cursor to the specified target.

'called from: ide://goto?Module=B4XMainPage&Sub=Button1_Click

Module is optional, the current module is set by default.
Line can be used instead of Sub to jump to a specific line.

run:
Runs an external program. It can be a batch file, a B4J jar file (UI or non-UI) or an executable.
You can pass arguments with the Args parameter, which can be used multiple times.
For example the B4XPages templates includes this line:

'Ctrl + click to export as zip: ide://run?File=%B4X%\Zipper.jar&Args=Project.zip

It calls a B4J program from the internal installation folder named Zipper.jar. It is similar to the built-in 'export as zip' feature but works with cross platform projects.
Note that the external program working directory will be the current project Objects folder.

Notes

• Spaces should be replaced with +.
• The parameters values are url decoded.
• The ide://run method supports these additional arguments:
  • FilesSync=True - Causes the IDE to sync the Files folder after operation completes.
  • CleanProject=True - Causes the IDE to clean the project after operation completes.
  • VMArgs - Similar to Args but added as a JVM argument.
    You can add: VMArgs=-DZeroSharedFiles%3DTrue to a zipper call to delete the content of the platform specific copies of shared files (the content will be added back when the program runs, because of the custom build action).
• The parameter values can include the following case sensitive aliases:
  • %B4X% - installation folder.
  • %PROJECT% - project folder (location of the project .B4? file).
  • %PROJECT_NAME% - project name.
  • %JAVABIN% - configured java bin folder (not available in beta #1)
  • %ADDITIONAL% - Platform specific additional libraries folder.
  • Any other environment variable.

How can I put the following route?

    '  ide://run?file="C:\Program+Files+(x86)\Microsoft+Visual+Studio\VB98\VB6.EXE

The link only goes as far as )
ide://run?file="C:\Program+Files+(x86

Thanks

You don't need the quotes. Change the ')' with %29

 

[Erel]

Open a folder with explorer:

'open project objects folder: ide://run?File=%WINDIR%\System32\explorer.exe&Args=%PROJECT%\Objects

 

[Erel]

B4A & B4J: Build without running, based on the command line builder:

'click to build: ide://run?File=%B4X%\B4ABuilder.exe&Args=-Task%3DBuild&Args=-BaseFolder%3D..

You can add more parameters. Note that you need to change '=' with %3D in the parameters (if you add more parameters).
Change B4ABuilder to B4JBuilder in B4J.

Open Github Desktop:

'github desktop ide://run?file=%WINDIR%\System32\cmd.exe&Args=/c&Args=github&Args=..\..\

The repository path matches a B4XPages project. Change to ..\ if not using B4XPages.

Tip:
gitignore:

**/Objects
**/AutoBackups
*.meta

 

[Erel]

Add to B4XMainPage in B4XPages project to open the project in the other tools:

'B4A ide://run?file=%WINDIR%\System32\cmd.exe&Args=/c&Args=start&Args=..\..\B4A\ProjectName.b4a
'B4i ide://run?file=%WINDIR%\System32\cmd.exe&Args=/c&Args=start&Args=..\..\B4i\ProjectName.b4i
'B4J ide://run?file=%WINDIR%\System32\cmd.exe&Args=/c&Args=start&Args=..\..\B4J\ProjectName.b4j

Change ProjectName with your project name.

The file:// scheme doesn't support the special variables that are supported by the more sophisticated ide:// scheme.

When needed you can use the ide:// scheme to open local files with:

'open the b4xlib manifest file with notepad++ ide://run?file=%COMSPEC%&args=/c&args=%PROJECT%\manifest.txt

(%COMSPEC% = path to cmd.exe, same as %WINDIR%\System32\cmd.exe)
