C plugin arguments

[jerome falken]

Stataers,

I wrote a C plugin that I can call using this code:

program r
  preserve
  version 14.2
  syntax varlist(min=1 max=10) [if] [in], k(string)

  plugin call riemann `varlist', "`k'"
end
qui program riemann, plugin using ("riemann.plugin")

Rightfully, in the code argv[0] points to k, the first argument of arglist, therefore invoking the plugin is done as such:
r w a s d, k("my string")

I would prefer the syntax to be as such:
r "my string" w a s d

What are/would be the modifications to the program above to support this syntax, which I think is much more readable.

Thank you for reading

program r

  syntax anything  [if] [in] , 
  
  gettoken mystring 0 : 0
  syntax varlist  [if] [in] ,
  
end

I believe you probably mean this?

program r
  preserve
  version 14.2
  syntax anything [if] [in],
  gettoken mystring 0:0
  syntax varlist(min=1 max=10) [if] [in],

  plugin call riemann "`mystring'" `varlist'
end

But that didn't work for me:

r "hello world" w a s d
"hello world invalid name
r(198);

I would prefer the syntax to be as such:
r "my string" w a s d

program r
 
  syntax anything  [if] [in] ,
  gettoken k 0 : 0
  syntax varlist(min=1 max=10) [if] [in],

  plugin call riemann `varlist', "`k'" 
  
end

 set trace on

r "my string" w a s d if 1==1 in 1/10

  --------------------------------------------------------------------------------------------------------------------------------------------------------- begin r ---
  - syntax anything [if] [in] ,
  - gettoken k 0 : 0
  - syntax varlist(min=1 max=10) [if] [in],
  - plugin call riemann `varlist', "`k'"
  = plugin call riemann w a s d, "my string"
  ----------------------------------------------------------------------------------------------------------------------------------------------------------- end r ---

That works perfectly, thank you!
