Load SKILL file, call procedure and get return value (string) from Linux Terminal

mohebur

I need to call few SKILL procedure one by one. Each of the procedure is written in it's own file. So I need to load the SKILL file before calling the procedure. I also need the return value; generally a string might be some other data type; from the calling procedure. I know I can write the commands in a file and use "virtuoso -nograph -replay commands_file" to load and run the procedures. Is there a way to load file and call procedure without writing in a file? How can I get the return values?

    That script called shout.il should answer your needs :

    ;; copyleft ebecheto
    defun( shout (command @optional (rmNL nil) (verb t) )
    (let (ipcId ret) ;// not to use with complex shell command , no time stamp specified
    ipcId=ipcBeginProcess(command)
    ipcWaitForProcess(ipcId)
    ret=ipcReadProcess(ipcId 30) ;=>"now you see it..."
    when(verb printf("SHELL>%s" ret))
    when(rmNL rexCompile("\n") ret=rexReplace( ret "" 1));<== bad idea if multiline answer...
    ret
    ))
    printf("shout(\"hostname\")\n")
    printf("ret=shout(\"ls *.log\")\n")
    printf("ret=shout(\"env\")\n")
    printf("ret=shout(\"echo $SHELL\")\n")
    printf("ret=shout(\"spectre -help bsim3v3\")\n")
    printf("ret=shout(\"cds_root virtuoso\")\n")
    ;printf("ret=shout(\"echo `date +'_%Hh%M_%F'`\")\n")
    printf("ret=shout(\"echo `date +'%%F_%%Hh%%M_'`\")\n")
    ;printf("ret=shout(\"echo `date +F`TATA\")\n")

    Don't shout it too loud though.

    Hope it helps,

    I think you misunderstood my question. I don't want to call shell commands from SKILL function. I want to call SKILL function from shell (csh in my case). I need to load .il file, call the function and get return value from the function.

    There isn't really a direct way to do this, but it's easy enough to implement with a bit of thought (it's a bit of an odd request though). You could have a generic script called generic.il:

    errset(load(getShellEnvVar("SOURCEFILE")))
returnVal=errsetstring(getShellEnvVar("FUNCTIONTOCALL"))
printf("RETURN VAL:%L\n" car(returnVal))
exit()

    Then you create this simple wrapper shell script, runSingleCommand:

    #!/bin/sh

export SOURCEFILE=$1
export FUNCTIONTOCALL=$2
virtuoso -nograph -restore generic.il | grep "^RETURN VAL:" | sed -e 's/^RETURN VAL://'

    Here's an example of a trial script to try it with, trial.il :

    procedure(helloWorld(a)
  strcat("Hello World " a)
)

    And finally how you run it:

    UNIX> runSingleCommand trial.il 'helloWorld("Andrew")'
    "Hello World Andrew"

    Regards,

    Andrew.

    Thanks Andrew. It's a bit workaround but it works.
