Sed - replace a string with a character of another line

Question

I am trying to write a script to reformat some text.

pages: page1: gui-rows: 6 items: '6': material: CAT_SPAWN_EGG buy: 999999999 sell: -1 '7': material: CAVE_SPIDER_SPAWN_EGG buy: 999999999 sell: -1 page2: gui-rows: 6 '8': material: CHICKEN_SPAWN_EGG buy: 999999999 sell: -1 

The expected output would be

 '6': type: item item: material: CAT_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: 6 '7': type: item item: material: CAVE_SPIDER_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: 7 '8': type: item item: material: CHICKEN_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: 8 

Using this cat 0.yml | sed "/page.*/d" | sed "/gui-row.*/d" | sed "/item.*/d" | sed "s/ / /g" | sed "s/.*':/&\\n type: item\\n item:/g" | sed "s/material.*/ &/g" |sed "s/buy/buyPrice/g" | sed "s/sell/sellPrice/g" | sed "s/sell.*/&\n slot: X" I get this:

 '6': type: item item: material: CAT_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: X '7': type: item item: material: CAVE_SPIDER_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: X '8': type: item item: material: CHICKEN_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: X

Using any POSIX awk:

$ cat tst.awk { gsub(/^[[:space:]]+|[[:space:]]+$/,"") } match($0,/^[^:]+:/) { tag = substr($0,1,RLENGTH-1) val = substr($0,RSTART+RLENGTH) sub(/[[:space:]]+$/,"",tag) sub(/^[[:space:]]+/,"",val) if ( gsub(/\047/,"",tag) ) { prt() val = tag tag = "slot" } t2v[tag] = val } END { prt() } function prt( indent) { indent = 4 printf "%*s\047%s\047:\n", indent, "", t2v["slot"] indent += 2 printf "%*s%s: %s\n", indent, "", "type", "item" printf "%*s%s:\n", indent, "", "item" indent += 2 printf "%*s%s: %s\n", indent, "", "material", t2v["material"] indent -= 2 printf "%*s%s: %s\n", indent, "", "buyPrice", t2v["buy"] printf "%*s%s: %s\n", indent, "", "sellPrice", t2v["sell"] printf "%*s%s: %s\n", indent, "", "slot", t2v["slot"] delete t2v } 

$ awk -f tst.awk 0.yml '6': type: item item: material: CAT_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: 6 '7': type: item item: material: CAVE_SPIDER_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: 7 '8': type: item item: material: CHICKEN_SPAWN_EGG buyPrice: 999999999 sellPrice: -1 slot: 8
