awk, sed, or other text processing suggestions, please
I have the following repeating pattern of text that needs to be reformatted.
Normally this should be easy, even with a standard text editor, but in this case I need to expand the information in the parenthesis and enumerate them.
Best I give an example:
"Gene Code (1A - 1F) D2 fragment, D74F"
I need to be able to have the final product look like this:
Gene Code, 1A, D2 fragment, D74F
Gene Code, 1B, D2 fragment, D74F
Gene Code, 1C, D2 fragment, D74F
Gene Code, 1D, D2 fragment, D74F
Gene Code, 1E, D2 fragment, D74F
Gene Code, 1F, D2 fragment, D74F
The snag is that the initial string contained in the parenthesis, could be anything like 1A-1F, or 3D-3H, etc. That is the only shifting bits of information. The numeric in the parenthesis is always the same, just the alphabetic letters need expansion with their associated number.
So someway of correlating the alphabet with the numbers is needed.
This looks like a mind-bender to me. Any help much appreciated. New to this, by the way.

Is this performance-sensitive? An easy solution with a for loop would be not very fast.

This bash script
#!/bin/bash
PART1=$(echo "$1" | sed 's/(.*)s(.*/1/')
PART3=$(echo "$1" | sed 's/.*)(.*)/1/')
PART2=$(echo "$1" | sed 's/.*(s*(.*)).*/1/')

END=$(echo "$PART2" | sed 's/.*-s*//')
STARTNUM=$(echo "$START" | sed 's/^(.).*/1/')
ENDNUM=$(echo "$END" | sed 's/^(.).*/1/')
if test "$STARTNUM" '!=' "$ENDNUM"; then
echo "Error: Numeral is different"
exit 1
fi
STARTLETTER=$(echo "$START" | sed 's/^.(.).*/1/')
ENDLETTER=$(echo "$END" | sed 's/^.(.).*/1/')
OUTPUT=''
for LETTER in A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ; do
test "$LETTER" '==' "$STARTLETTER" && OUTPUT='yes'
test -n "$OUTPUT" && echo "$PART1, $STARTNUM$LETTER,$PART3"
test "$LETTER" '==' "$ENDLETTER" && OUTPUT=''
done
Will do what you need, albeit not in a very performant way when called with the original text as $1
EDIT
As requested a few words about the sed
expressions:
- I isolate
PART1
by taking everything before whitespace and an opening(
- I isolate
PART3
by taking everything from the closing)
onwards - I isolate
PART2
by taking what is between(
and)
, ignoring whitespace
START
andEND
are isolated by the dash, again ignoring whitespace- Number and Letter are isolated by being first and second character
A breakdown of the sed expressions would be fantastic, looks like some sub-expressions, and as
that does...?

If GNU sed is available
sed -r 's/([^(]+) ((.)(.) - .(.))(.*)/printf x271, 2%s,5\nx27 {3..4}/e' <<<'Gene Code (1A - 1F) D2 fragment, D74F'

If not, run it sending as pipe to the shell

A perl way:
#!/usr/bin/perl
use feature 'say';
my $str = '"Gene Code (3D - 3H) D2 fragment, D74F"';
# get begin number, begin letter, end number, end letter
my ($bn,$bl,$en,$el) = $str =~ /((.)(.) - (.)(.))/;
# loop from begin letter to end letter
for my $i ($bl .. $el) {
# do the substitution and print
($_ = $str) =~ s/ (.. - ..)/, $bn$i,/ && say;
}
Output:
"Gene Code, 3D, D2 fragment, D74F"
"Gene Code, 3E, D2 fragment, D74F"
"Gene Code, 3F, D2 fragment, D74F"
"Gene Code, 3G, D2 fragment, D74F"
"Gene Code, 3H, D2 fragment, D74F"
Thank you everyone for providing these great solutions. I'm really awed by the generosity and professionalism. It works! I didn't know sed was so powerful. Now I need to figure out how to pass over the entries that don't match this specific pattern. Thank you all and have a great New Year!!

A version that doesn't require looping, and uses only four calls to sed. Granted though, my version doesn't check that the two numerics are equal. In fact, the second one is ignored and can even be omitted, as with "Gene Code (91K - Q) D2 fragment, D74F"
. Also the low bound and high bound can appear in either order. If the low bound is greater than the high bound, then the output sequence is reversed.
$ cat foo
#!/usr/bin/env bash
# Script to expand $1 passed as:
# "Gene Code (91K - 91Q) D2 fragment, D74F"
#
# into the output:
#
# Gene Code, 91K, D2 fragment, D74F
# Gene Code, 91L, D2 fragment, D74F
# Gene Code, 91M, D2 fragment, D74F
# Gene Code, 91N, D2 fragment, D74F
# Gene Code, 91O, D2 fragment, D74F
# Gene Code, 91P, D2 fragment, D74F
# Gene Code, 91Q, D2 fragment, D74F
# Copy $1 into FMT_STRING, replacing the " (91K - 91Q)" bit with a ', %s,'
# printf directive, such as 'Gene Code, %s, D2 fragment, D74F':
FMT_STRING="$(sed -e 's/ (.* - .*)/, %s,/' <<< "$1")"
# Parse the beginning and ending bounds and format them with just a
# space between, such as '91K 91Q':
BOUNDS="$(sed -e 's/^[^(]*((.*) - (.*)) .*/1 2/' <<< "$1")"
# Extract the (first) static numeric part from BOUNDS, e.g. '91'
NUMERIC="$(sed -e 's/[^0-9].*//' <<< "$BOUNDS")"
# remove all digits [0-9] from BOUNDS, e.g. 'K Q'
BOUNDS="$(sed -e 's/[0-9]//g' <<< "$BOUNDS")"
FMT_STRING="$(printf "$FMT_STRING" "${NUMERIC}%c")"
jot -w "$FMT_STRING" - $BOUNDS
Sample output:
$ ./foo "Gene Code (737L - 737X) D2 fragment, D74F"
Gene Code, 737L, D2 fragment, D74F
Gene Code, 737M, D2 fragment, D74F
Gene Code, 737N, D2 fragment, D74F
Gene Code, 737O, D2 fragment, D74F
Gene Code, 737P, D2 fragment, D74F
Gene Code, 737Q, D2 fragment, D74F
Gene Code, 737R, D2 fragment, D74F
Gene Code, 737S, D2 fragment, D74F
Gene Code, 737T, D2 fragment, D74F
Gene Code, 737U, D2 fragment, D74F
Gene Code, 737V, D2 fragment, D74F
Gene Code, 737W, D2 fragment, D74F
Gene Code, 737X, D2 fragment, D74F
Reversing the bounds reverses the output:
$ ./foo "Gene Code (737X - 737L) D2 fragment, D74F"
Gene Code, 737X, D2 fragment, D74F
Gene Code, 737W, D2 fragment, D74F
Gene Code, 737V, D2 fragment, D74F
Gene Code, 737U, D2 fragment, D74F
Gene Code, 737T, D2 fragment, D74F
Gene Code, 737S, D2 fragment, D74F
Gene Code, 737R, D2 fragment, D74F
Gene Code, 737Q, D2 fragment, D74F
Gene Code, 737P, D2 fragment, D74F
Gene Code, 737O, D2 fragment, D74F
Gene Code, 737N, D2 fragment, D74F
Gene Code, 737M, D2 fragment, D74F
Gene Code, 737L, D2 fragment, D74F

A perl way:
#!/usr/bin/perl
use feature 'say';
my $str = '"Gene Code (3D - 3H) D2 fragment, D74F"';
# get begin number, begin letter, end number, end letter
my ($bn,$bl,$en,$el) = $str =~ /((.)(.) - (.)(.))/;
# loop from begin letter to end letter
for my $i ($bl .. $el) {
# do the substitution and print
($_ = $str) =~ s/ (.. - ..)/, $bn$i,/ && say;
}
Output:
"Gene Code, 3D, D2 fragment, D74F"
"Gene Code, 3E, D2 fragment, D74F"
"Gene Code, 3F, D2 fragment, D74F"
"Gene Code, 3G, D2 fragment, D74F"
"Gene Code, 3H, D2 fragment, D74F"
Thank you everyone for providing these great solutions. I'm really awed by the generosity and professionalism. It works! I didn't know sed was so powerful. Now I need to figure out how to pass over the entries that don't match this specific pattern. Thank you all and have a great New Year!!

A version that doesn't require looping, and uses only four calls to sed. Granted though, my version doesn't check that the two numerics are equal. In fact, the second one is ignored and can even be omitted, as with "Gene Code (91K - Q) D2 fragment, D74F"
. Also the low bound and high bound can appear in either order. If the low bound is greater than the high bound, then the output sequence is reversed.
$ cat foo
#!/usr/bin/env bash
# Script to expand $1 passed as:
# "Gene Code (91K - 91Q) D2 fragment, D74F"
#
# into the output:
#
# Gene Code, 91K, D2 fragment, D74F
# Gene Code, 91L, D2 fragment, D74F
# Gene Code, 91M, D2 fragment, D74F
# Gene Code, 91N, D2 fragment, D74F
# Gene Code, 91O, D2 fragment, D74F
# Gene Code, 91P, D2 fragment, D74F
# Gene Code, 91Q, D2 fragment, D74F
# Copy $1 into FMT_STRING, replacing the " (91K - 91Q)" bit with a ', %s,'
# printf directive, such as 'Gene Code, %s, D2 fragment, D74F':
FMT_STRING="$(sed -e 's/ (.* - .*)/, %s,/' <<< "$1")"
# Parse the beginning and ending bounds and format them with just a
# space between, such as '91K 91Q':
BOUNDS="$(sed -e 's/^[^(]*((.*) - (.*)) .*/1 2/' <<< "$1")"
# Extract the (first) static numeric part from BOUNDS, e.g. '91'
NUMERIC="$(sed -e 's/[^0-9].*//' <<< "$BOUNDS")"
# remove all digits [0-9] from BOUNDS, e.g. 'K Q'
BOUNDS="$(sed -e 's/[0-9]//g' <<< "$BOUNDS")"
FMT_STRING="$(printf "$FMT_STRING" "${NUMERIC}%c")"
jot -w "$FMT_STRING" - $BOUNDS
Sample output:
$ ./foo "Gene Code (737L - 737X) D2 fragment, D74F"
Gene Code, 737L, D2 fragment, D74F
Gene Code, 737M, D2 fragment, D74F
