CAPL script printing functions write, writeex, writelineex, writetolog, writetologex, writedbglevel do you really know which one to use under what circumstances?

Preface

• Engaged in industry “ several tens of years ”, You can always meet these printing functions on different occasions , What's the difference , Today, the blogger will give the students a wisp
• Demonstrate hardware and software environment Win10 x64 ; CANoe 11 SP2 x64
• This chapter demonstrates the source code download , Click the jump

write

1️⃣ First create the project and file , For demonstration

---

2️⃣ write It is the simplest and most commonly used printing function , Post it here , It is to make you familiar with the print formats of different data types .

---

3️⃣ Testing process , Output Soure The type is CAPL/.NET

on key 'a'
{
    
  write ("pressed key %c",this);
}

writeEx

1️⃣ writeEx Just like write More complicated , You can specify the display position of printing , You can also specify the type of printing

• writeEx It will print on the last line of the window , That is to say No line wrapping

---

2️⃣ Testing process , Printed on Trace On , Remember trace Of CAPL To check

on key 'b'
{
    
  writeEx (TraceWindow,Information,"pressed key %c",this);
  
}

---

3️⃣ Testing process , It can be seen that the output is System Page , And printing without line breaks

on key 'c'
{
    
 
  writeEx (SystemWindow,Information,"pressed key %c",this);
  writeEx (SystemWindow,Warning,"pressed key %c",this);
}

writeLineEX

1️⃣ and writeEx The difference between printing and wrapping , You can specify the display position of printing , You can also specify the type of printing

---

2️⃣ Testing process

on key 'd'
{
    
 
  writeLineEx (SystemWindow,Information,"pressed key %c",this);
  writeLineEx (SystemWindow,Warning,"pressed key %c",this);
}

---

writeToLog

1️⃣ writeToLog seeing the name of a thing one thinks of its function , That is to say Logging The document writes something ,

---

2️⃣ Since it's to logging File write data , Then create a logging Block , Set to CAPL Triggered mode , need logging

---

3️⃣ The test code is as follows ：

On key 'f' 
{
    
    char timeBuffer[64];
    getLocalTimeString(timeBuffer);
    write("pressed key %d",this);
  
    setLogFileName("logging", "test.asc");

    startLogging("logging",100);
    writeToLog("%s *************writeToLog*************",timeBuffer);
    writeToLogEx("%s: *************writeToLogEx*************",timeBuffer);
  
    stopLogging("logging",100);
}

---

4️⃣ Output results

• writeToLog and writeToLogEx The difference can also be seen ,writeToLog Just print more “// Time stamp ”
  

writeToLogEx

writeDbgLevel

1️⃣ This is very easy to use with functions , I suggest you learn to use , In larger projects , It is not recommended to use write and writeLineEx
Wait for the output function to debug the code , Because we can't control these debug Output or not

• This function can decide whether to print it according to priority
• The first parameter is to specify priority , The lower the number is , Description higher priority ,debug The more likely information is to be output , Of course , It depends on setWriteDbgLevel Set priority
• 0 The highest priority , If setWriteDbgLevel（0）, So every time I call writeDbgLevel function , The first argument must be =0 , Can be output , Otherwise the output is suppressed
• 15 Has the lowest priority , If setWriteDbgLevel（15） So every time I call writeDbgLevel function , The first parameter is equal to whatever , Can output
• In actual development , We will pass weite too debug Our code , After debugging , We don't expect this debug The information is printed , Then we can go through setWriteDbgLevel Function to increase the output priority , Achieve the purpose of inhibiting output
• It is recommended to use ,

2️⃣ Test code and test results

On key 'g' 
{
    

  setWriteDbgLevel(7);
  writeDbgLevel (4, "This is shown:");
   // Output: This is shown
  writeDbgLevel (9, "This is not shown");
   // No output
}

End
