Get Dyalog version information in function
Dear all,
Is there a way to get the information from ]version in a function. I would like to know at runtime at which OS I am running on.
Kind regards,
Florian

Re: Get Dyalog version information in function
That is an interesting question !
At the simplest level you can look
However it doesn't differentiate between, for example, Linux on x86 and Linux on Arm. The following snippet of code attempts to do this (it's from NonWindows.Setup in the supplied quadna workspace):
However, that I now realise has its limitations: on macOS it doesn't distinguish between running on Intel-based Macs or ARM-based Macs under Rosetta (or for the future, a native ARM-based Dyalog running on ARM).
However, let's cross that bridge when we come to it. I'd go with the code above, but make sure that it's in a cover function: watch this space for a possible better solution to this !

3↑⊃'.'⎕wg'APLVersion'which will tell you what O/S you're running on: Win, Lin, AIX, Mac.

:Select 3↑⊃'.'⎕WG'APLversion'
:Case 'AIX'
opsys←'AIX'
:Case 'Mac'
opsys←'Mac'
:Case 'Win'
opsys←'Windows'
:Case 'Lin'
:Select 4↑⊃⎕SH'uname -a'
:Case 'armv'
opsys←'Pi'
:Else
opsys←'Linux'
:EndSelect
:EndSelect

apledition←⊃(80=⎕DR' ')↓'Classic' 'Unicode'
aplwidth←{z←⍵ ⋄ 2×⍬⍴⎕SIZE'z'}⍬

Re: Get Dyalog version information in function
Of course, you can do this (which may not be recommended):
- Code: Select all
capture← ⎕SE.UCMD'Version' ⍝ Execute an arbitrary user command
capture
- Code: Select all

Hi Andy,
Great. Thank you for this interesting solution.
I needed it to decide how to issue some correct system commands.
Best regards
