Lianja 6.4 will be the next general release expected this month.

I have uploaded Lianja 6.4Beta3 for Windows for those of you who have access to pre-release versions.

This is pre-release software so it should not be used in production.

Changes since 6.3.2

  1. Added built-in support for KVS in Python as described here.
  2. You can now use the Python pip command directly in the Lianja/VFP console tab e.g. to install the numPy package in the current App:

    e.g. to install numpy

    Code:
    set backticks on
pip install --target=`cd`\python3\ numpy
  3. Added some new KVS functions.

    kvsid = kvs_open("filename.kvs" [, lShared] ) // you can now open a KVS shared or exclusive
    cnt = kvs_removerange(kvsid, nStart, nCount)
    cnt = kvs_loadFromFile(kvsid, "filename.txt")
    cnt = kvs_saveToFile(kvsid, "filename.txt")
    cnt = kvs_generate(kvsid, nCount)
  4. Added some new built-in Python functions.

    str = filetostr(filename)
    strtofile(string, filename [, nFlag])
  5. Added support for the VFP amembers() function (with enhancements).

    cnt = amembers(arr, object | classname [, 1])

    Arr is 4D array when third parameter is 1 otherwise 2D

    Arr[n, 1] = membername
    Arr[n, 2] = Property | Method
    Arr[n, 3] = datatype
    Arr[n, 4] = value

    build an object browser like this:

    Code:
    aselobj(arr)
amembers(arr2, arr[1], 1)
select 0
create table if not exists _amembers (name char(32), type char(20), datatype char(20), value char(255))
use _amembers
zap
append from array arr2
goto top
browse
  6. Added support for the VFP aselobj() function (with enhancements)

    cnt = aselobj(arr)

    Arr[1] = activepage
    Arr[2] = activesection
    Arr[3] = activeformitem
    Arr[4] = activegridcolumn
    Arr[5] = objectundercursor
  7. Added new Camera Custom UI framework class

    • Build and run automatically by clicking "Desktop App View"
    • Output is placed in x:\lianja\standaloneapps\appname\ as a self contained app directory
    • You can zip this directory up and copy to distribute then install anywhere on a target machine
    • These GUI apps are currently windows specific
    • Useful for building small native GUI apps
    • File <appname>.prg, <appname>.py or <appname>.js is the app entrypoint dependent on the scripting language
    • Run app “appname.exe” in the x:\lianja\standaloneapps\appname\ directory
