Hello list,
recent update of context suite (beta) changed something in the code of
'mtxrun' so now it shows me a warning:
${CONTEXT}/bin/mtxrun:20683: attempt to concatenate a nil value (field 'platform')
I didn't notice this warning earilier.
The line 20683 in 'mtxrun' is
local texos="texmf-"..os.platform
To check the return of 'os.platform' I made small lua script and run it
as
mtxrun --script SCRIPT --platform=linux-64
It returned 'nil nil'. Is this expected behavior?
% SCRIPT.lua
----------------------- 8< ------------------------
local plat=os.platform
local plat2=os.getenv("MTX_PLATFORM")
print("platform = ", plat)
print("platform2 = ", plat2)
----------------------- 8< ------------------------

it should be
local platform = os.getenv("MTX_PLATFORM") or ""

Thank you, now 'mtxrun' runs without any warnings.
