BlackBox Component Builder 1.7
Download beta version
Migration from 1.6
The several typical changes you should do for adopting your subsystems for 1.7 are listed bellow:
IN to VAR
Now it is forbidden to use a variable declared as IN parameter as the receiver of a method call that expects a VAR parameter. You should change the IN parameter to VAR or the VAR receiver to IN in such a case.
With 1.7 you can not call the methods of a read-only variable object if there is VAR option in argument of method. So you should export such a variable by *.
WinNet.hostnet definition was changed, so you need to replace:
inaddr := hostentry.h_addr_list^^
inaddr := SYSTEM.VAL(WinNet.in_addr, hostentry.h_addr_list^^)
Underlined white space
Underlined spaces and tabs are now shown according to the defined format, i.e. they are underlined. So we recommend you to check your documentation files and/or program generated text files to prevent unexpected underlines.
UTF-8 conversion supported "out of the box" from module
Strings. So if you are using UTF-8 conversions embedded in your own code or from some third-party modules, you can switch to the new Strings procedures.
1.7 supports calling URLs (e.g. web pages, E-mails), so now you can be sure that the user can call your link from documentation even if external CPC subsystems such as Info or i21Sys are not installed.
Dialog.OpenExternal procedure to call a URL.
Config & Converters
The new Converter.next* export allows uninstalling and ordering converters "on the fly" from any module not just from the Config module used at BlackBox startup.
Useful tools for migration
There is the tool for batch compilation of subsystems: ypkDevTool.
