skill - write a file with skill variables

ejm20

 

In skill, how do you create a file and overwrite if its present with the contents that are skill variables?  Heres a snipet of the the code to get produce the variables:

      tool_opt=testSession~>simID~>data~>env~>data~>turboOpts~>data~>uniMode~>value
         println( tool_opt )

      rcReduction_opt=testSession~>simID~>data~>env~>data~>turboOpts~>data~>psrSwitch~>value
         println( rcReduction_opt )

      println( mt_opt )    

 The evaluated variables will then be written into a file named "myFile"  .   As an example:

tool_opt   =  spectre

rcReduction = nil

mt_opt  =  Disable

 so......

 

spectre nil Disable

 

Thanks

  • Hi,

    One thing that I would add is that this is fine if you are sure that the variables are all strings, but if not then it may be better to use "%L" for each of the format specifiers - if the variable was not a string then the %s format would cause fprintf (or sprintf or printf) to choke and fail, but %L can be used for any value, 'nil', a list, an integer, a floating point number etc.  You can use the "type" function to obtain the type of a variable, or individual predicate functions like "stringp", "listp" etc. to programmatically test and avoid such an issue also.  E.g. 

    if(forall(var list(tool_opt multiThread paraReduction) stringp(var)) then
  ;; print variables out nicely if they are all strings
  fprintf(myPort "%s %s %s\n" tool_opt  multiThread  paraReduction )
else
  ;; print values out using default %L format if they are not all strings
  fprintf(myPort "%L %L %L\n" tool_opt  multiThread  paraReduction )
)

    You could even build the format string based on the variable data type (that seems overkill here).
