Checking against text from a file

climbnc

Hi All,

I have a file i want to read.  This file consists of lines like

RUN DRC YES

RUN LVS YES

POWER NAMES VCC VCCA

i have some outputs of Buttons and stringFields from a GUI that i set to a string like

setPowerNames = sprintf(str "POWER NAMES %s" powerStringField~>value)

if(drcBooleanButton = t

then

setDrcSwitch = "RUN DRC YES"

else

setDRCSwitch = "RUN DRC NO"

)

I want to then compare all the lines from the file against setPowerNames,setDrcSwitch, etc.  Then i would ouput the lines that are different from the file to an output file(compare.results.text)

What would be the most efficient way to do this?

Thank you in advance for your help. 

  • i want to clarify that i would be checking setPowerNames to then line
    POWER NAMES VCC VCCA

    compare setDrcSwtich to the line
    RUN DRC YES

    and so on.

    So that if setDrcswitch = "RUN DRC NO" and then line from the file is RUN DRC YES
    then it would output RUN DRC YES to the compare.results.text

  • It probably depends on how many of these switches you have, but I'd think you'd want to do something like this:

    linePrefixes=list("POWER NAMES" "RUN DRC" "RUN LVS")
    patterns=makeTable('patterns nil)
    foreach(linePrefix linePrefixes
      patterns[linePrefix]=pcreCompile(strcat("^\\s*" linePrefix "\\s*"))
    )

    trailingSpaces=pcreCompile("\\s*$")

    settingsFromFile=makeTable('settingsFromFile nil)
    inp=infile("settings.txt")
    while(gets(line inp)
      line=pcreReplace(trailingSpaces line "" 1)
      forall(linePrefix patterns
        if(pcreExecute(patterns[linePrefix] line) then
          settingsFromFile[linePrefix]=pcreReplace(patterns[linePrefix] line "" 1)
          nil
        else
          t
        )
      )
    )
    close(inp)

    This will give  you a hash table with settingsFromFile["RUN DRC"] and settingsFromFile["POWER NAMES"] etc.

    Then, in your code above, rather than setting individual variables such as setDrcSwitch, I'd suggest you do:

    settingsFromForm=makeTable('settingsFromForm nil)

    and then in the code:

    if(drcBooleanButton = t then
      settingsFromForm["RUN DRC"]="YES"
    else
      settingsFromForm["RUN DRC']="NO"
    )

    (actually I'd probably write it this way):

    settingsFromForm["RUN DRC"]=if(drcBooleanButton then "YES" else "NO")

    Having done that you could then look for the differences (and write to file, or whatever you want):

    foreach(setting settingsFromForm
      when(settingsFromForm[setting]!=settingsFromFile[setting]
        printf("Setting %s doesn't match\n" setting)
      )
    )

    Regards,

    Andrew.

  • Thank you very much Andrew. This helps a lot.
