* resolving unnamed return value in place.

[Ron Melby]

local _pl = string.format('%s%s%s', __ipath.temp, ((rtvpgnam())), '.fh_prf')
ipath resolves in place
how do I get rtvpgnam to resolve in place? there is one return value

local _pl = string.format('%s%s%s', __ipath.temp, rtvpgnam(), '.fh_prf') should work OK.
You don't need the enclosing parentheses if rtvpgnam() only has one return value.

However, that return value must be a text string to satisfy the %s format.
If it is not a text string then tostring(rtvpgnam()) might convert it, but won't work if the return value is a table or a pointer.

I absolutely think it should work too, and I must be missing something simple. I am sure I have done this type of thing before.

fred = rtvpgnam()
local _pl = string.format('%s%s%s', __ipath.temp, rtvpgnam(), '.fh_prf')
local _pl = string.format('%s%s%s', __ipath.temp, rtvpgnam, '.fh_prf')
local _pl = string.format('%s%s%s', __ipath.temp, tostring(rtvpgnam()), '.fh_prf')

fred = "fhF264"
bad argument #2 to 'format' (string expected, got function)
is the errror for any of the three _pl statements


and here is the function, just because:

function rtvpgnam()
local pg = fhGetContextInfo('CI_PLUGIN_NAME')
if pg == '' then
pg = debug.getinfo(2).source:gsub('.*~',''):gsub('%.%w*','') -- because fh sloshes out incorrect results again
end
return pg
end

You are trying to fix the wrong argument.
argument #1 to 'format' is '%s%s%s'
argument #2 to 'format' is __ipath.temp ~ so this is the bad function ~ try replacing it with a 'string'
argument #3 to 'format' is rtvpgnam()

i.e. Does the following fail?
local _pl = string.format('%s%s%s', 'xyz', rtvpgnam(), '.fh_prf')

dont know why my brain did not see '%s%s%s' as an arg. fixed, but more issues in the offing, thanks to non-consistent fh.
