### More Examples

| Find | Replace | Description/Expected Output | Regex | Scope CSV |
|---------------------|-------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------|-------|-----------|
| `;` | `cond(LCNT==5,";Column5;")` | Adds a 5th Column for each line into a `;` delimited file. | No | No |
| `key` | `set("key"..CNT)` | Enumerates key values by appending the count of detected strings. E.g., key1, key2, key3, etc. | No | No |
| `(\d+)` | `set(CAP1.."€ The VAT is: ".. (CAP1 * 0.15).."€ Total with VAT: ".. (CAP1 + (CAP1 * 0.15)).."€")` | Finds a number and calculates the VAT at 15%, then displays the original amount, the VAT, and the total amount. E.g., `50` becomes `50€ The VAT is: 7.5€ Total with VAT: 57.5€` | Yes | No |
| `---` | `cond(COL==1 and LINE<3, "0-2", cond(COL==2 and LINE>2 and LINE<5, "3-4", cond(COL==3 and LINE>=5 and LINE<10, "5-9", cond(COL==4 and LINE>=10, "10+"))))` | Replaces `---` with a specific range based on the `COL` and `LINE` values. E.g., `3-4` in column 2 of lines 3-4, and `5-9` in column 3 of lines 5-9 assuming `---` is found in all lines and columns.| No | Yes |
| `(\d+)\.(\d+)\.(\d+)`| `cond(CAP1 > 0 and CAP2 == 0 and CAP3 == 0, MATCH, cond(CAP2 > 0 and CAP3 == 0, " " .. MATCH, " " .. MATCH))` | Alters the spacing based on the hierarchy of the version numbers, aligning lower hierarchies with spaces as needed. E.g., `1.0.0` remains `1.0.0`, `1.2.0` becomes ` 1.2.0`, indicating a second-level version change.| Yes | No |
| `(\d+)` | `set(CAP1 * 2)` | Doubles the matched number. E.g., `100` becomes `200`. | Yes | No |
| `;` | `cond(LCNT == 1, string.rep(" ", 20- (LPOS))..";")` | Inserts spaces before the semicolon to align it to the 20th character position if it's the first occurrence. | No | No |
| `-` | `cond(LINE == math.floor(10.5 + 6.25 * math.sin((2 * math.pi * LPOS) / 50)), "*", " ")` | Draws a sine wave across a canvas of '-' characters spanning at least 20 lines and 80 characters per line. | No | No |
| `^(.*)$` | `init({MATCH_PREV=1}); cond(MATCH == MATCH_PREV, ''); MATCH_PREV=MATCH;` | Removes duplicate lines, keeping the first occurrence of each line. Matches an entire line and uses `MATCH_PREV` to identify and remove consecutive duplicates. | Yes | No |

#### Engine Overview
MultiReplace uses the [Lua engine](https://www.lua.org/), allowing for Lua math operations and string methods. Refer to [Lua String Manipulation](https://www.lua.org/manual/5.4/manual.html#6.4) and [Lua Mathematical Functions](https://www.lua.org/manual/5.4/manual.html#6.6) for more information.
