I am trying to swap 2 columns in a specific block of a file. The file format is:
Code:

I am trying to
1) replace 5th column with 2nd column.
1-1) If a letter in 5th column is "r", this would be replaced with "v". If a letter in 5th column is "f", this would be replaced with "^".
2) insert two double quotation marks in 1st column.
3) replace 3rd column with ;
4) replace 4th column with //
This should only be done in blocks which are defined starting and ending lines - "input external delay" , "data arrival time".
Additionally, I want to change texts before/after the block with predefined texts. Before the block, I would like to add $path {
// from: in11
// to: out432
$name "test_1" ;
$cycle 1 ;
$slack -0.130978 ;
$transition {
After the block, I would like to add }
}
My expected output should be:
Code:
$path {
// from: in11
// to: out432
$name "test_1" ;
$cycle 1 ;
$slack -0.130978 ;
$transition {
"in11" v ; // (in)
"Ckt432/A[7]" v ; // (TopLevel432b)
"Ckt432/M1/A[7]" v ; // (PriorityA)
"Ckt432/M1/U7/Y" ^ ; // (INVX1_RVT)
"Ckt432/M5/U12/Y" v ; // (OA21X1_RVT)
"Ckt432/M5/Chan[3]" v ; // (DecodeChan)
"Ckt432/Chan[3]" v ; // (TopLevel432b)
"out421" v ; // (out)
}
}
$path {
// from: in11
// to: out432
$name "test_2" ;
$cycle 1 ;
$slack -0.130978 ;
$transition {
"in37" v ; // (in)
"Ckt432/A[5]" v ; // (TopLevel432b)
"Ckt432/M1/A[5]" v ; // (PriorityA)
"Ckt432/M1/U8/Y" ^ ; // (INVX1_RVT)
"Ckt432/M1/U13/Y" v ; // (NAND2X0_RVT)
"Ckt432/M5/U12/Y" v ; // (OA21X1_RVT)
"Ckt432/M5/Chan[3] " v ; // (DecodeChan)
"Ckt432/Chan[3] " v ; // (TopLevel432b)
"out421" v ; // (out)
}
}
Currently, I can swap columns, but I don't know how to use them only in the block. My code is:
Hi Experts,
I have a problem where I want to print missing columns (3,4) within a block of text. Each block is separated by "###". Some rows have missing column 3 and 4 which should be same as the previous value in column 3 and 4. The file is space delimited.
For example:
