Changing surrounding delimiters in VIM

Vim is magic. I had tu change the surrounding delimiters of strings.

Basically, I had text like below and wanted to replace the backquote delimiter.

| 0x10 | LDAi | 2 | Charge la valeur de l'opérande dans le registre A `[A := operande]` |
| 0x14 | LDAd | 2 | Charge la valeur dans la RAM pointée par l'opérande dans le registre A. `[A := Mem[opérande]]` |
| 0x18 | - | - | - |
| 0x1c | STA | 2 | Sauvegarde en mémoire la valeur du registre A à l'adresse donnée par l'opérande. `[Mem[opérande] := A]` |
| 0x20 | LDBi | 2 | Charge la valeur de l'opérande dans le registre B `[B := operande]` |
| 0x24 | LDBd | 2 | Charge la valeur dans la RAM pointée par l'opérande dans le registre B. `[B := Mem[opérande]]` |

Every string like \[A := operande]`was to be replaced by{++[A := operande]++}`.

To do so with, it is as easy as 1) visually selecting the lines where you want a modification (Ctrl + V), and 2) press “:” followed by the magic recipe

s/`\(.*\)`/{++\1++}/g

which stands for :

• s …. g : substitue globally in the grammar s/src_pattern/dst_pattern/g
• the source pattern is a repetition of which ever character .* we capture in a group by the surrounding ( and ); This source pattern is surrounded by the source delimiter, hence the backquotes
• the target pattern is the new delimiters surrounding the group copy/pasted with the \1
