This chapter provides an overview of the various match and replace options available in MultiReplace, enhancing the flexibility and precision of your search and replace operations.

Match Whole Word Only: When this option is enabled, the search term is matched only if it appears as a whole word. This is particularly useful for avoiding partial matches within larger words, ensuring more precise and targeted search results.

Match Case: Selecting this option makes the search case-sensitive, meaning 'Hello' and 'hello' will be treated as distinct terms. It's useful for scenarios where the case of the letters is crucial to the search.

Use Variables: This feature allows the use of variables within the replacement string for dynamic and conditional replacements. For more detailed information, refer to the Option 'Use Variables' chapter.

Replace First Match Only: The "Replace First Match Only" option is ideal for Replace-All operations, where it replaces only the first occurrence of a match in each list entry. This is particularly useful for different replace strings with the same find pattern. It's designed for modifying only the initial match in a document or scope, while keeping other instances intact. The same effect can be achieved with the 'Use Variables' option using cond(CNT == 1, 'Replace String') for conditional replacements.

Wrap Around: When this option is active, the search will continue from the beginning of the document after reaching the end, ensuring that no potential matches are missed in the document.

Scope functions define the range for searching and replacing strings:

• Selection Option: Supports Rectangular and Multiselect to focus on specific areas for search or replace.
• CSV Option: Enables targeted search or replacement within specified columns of a delimited file.
  • Cols: Specify the columns for focused operations.
  • Delim: Define the delimiter character.
  • Quote: Delineate areas where characters are not recognized as delimiters.

• Sorting Lines in CSV by Columns:Ascend or descend, combining columns in any prioritized order.
• Toggle Sort: Allows users to return columns to their initial unsorted state with just an extra click on the sorting button. This feature is effective even after rows are modified, deleted, or added.
• Deleting Multiple Columns: Remove multiple columns at once, cleaning obsolete delimiters.
• Clipboard Column Copying: Copy columns with original delimiters to clipboard.

• Exclude Header Lines from Sorting: Set HeaderLines=<number> in %USERPROFILE%\AppData\Roaming\Notepad++\plugins\config\MultiReplace\MultiReplace.ini to specify the number of top lines to exclude from sorting as headers.

• For accurate numeric sorting in CSV files, the following settings and regex patterns can be used:

Activate the 'Use Variables' checkbox to employ variables associated with specified strings, allowing for conditional and computational operations within the replacement string. This Dynamic Substitution is compatible with all search settings of Search Mode, Scope, and the other options.

Note: Utilize either the set() or cond() command in 'Replace with:' to channel the output as the replacement string. Only one of these commands should be used at a time.

Decimal Separator
When MATCH and CAP variables are used to read numerical values for further calculations, both dot (.) and comma (,) can serve as decimal separators. However, these variables do not support the use of thousands separators.

.. is employed for concatenation.
E.g., "Detected "..CNT.." times."

Directly outputs strings or numbers, replacing the matched text in the Replace String with the specified or calculated value.

Implements if-then-else logic, or if-then if falseVal is omitted. Evaluates the condition and pushes the corresponding value (trueVal or falseVal) to the Replace String.

Initializes custom variables for use in various commands, extending beyond standard variables like CNT, MATCH, CAP1. These variables can carry the status of previous find-and-replace operations to subsequent ones.

Custom variables maintain their values throughout a single Replace-All or within the list of multiple Replace operations. So they can transfer values from one list entry to the following ones. They reset at the start of each new document in 'Replace All in All Open Documents'.

Formats numbers based on precision (maxDecimals) and whether the number of decimals is fixed (fixedDecimals being true or false).

Note: The fmtN command can exclusively be used within the set and cond commands.

If-then logic is integral for dynamic replacements, allowing users to set custom variables based on specific conditions. This enhances the versatility of find-and-replace operations.

Note: Do not embed cond(), set(), or init() within if statements; if statements are exclusively for adjusting custom variables.

• if condition then ... end
• if condition then ... else ... end
• if condition then ... elseif another_condition then ... end
• if condition then ... elseif another_condition then ... else ... end

This example shows how to use if statements with cond() to manage variables based on conditions:

init({MVAR=""}); if CAP2~=nil then MVAR=MVAR..CAP2 end; cond(string.sub(CAP1,1,1)~="#", MVAR); if CAP2~=nil then MVAR=string.sub(CAP1,4,-1) end

MultiReplace uses the Lua engine, allowing for Lua math operations and string methods. Refer to Lua String Manipulation and Lua Mathematical Functions for more information.

Manage search and replace strings within the list using the context menu, which provides comprehensive functionalities accessible by right-clicking on an entry, using direct keyboard shortcuts, or mouse interactions. Here are the detailed actions available:

Right-click on any entry in the list or use the corresponding keyboard shortcuts to access these options:

Additional Interactions:

• Space Key: Toggles the activation state of selected entries, similar to using Alt+E to enable or Alt+D to disable.
• Double-Click: Mirrors the 'Transfer to Input Fields' action by transferring the contents of a row with their options to the input fields, equivalent to pressing Alt+Up.

• "Use List" checkbox toggles operation application between all list entries or the "Find what:" and "Replace with:" fields.

• Statistics Button: Located to the left of the list, this button when clicked, opens two new columns:
  • Find Count: Displays the number of times each 'Find what' string is detected.
  • Replace Count: Shows the number of replacements made for each 'Replace what' string.
• Note: The values in 'Find Count' and 'Replace Count' can differ, especially when 'Use Variables' is employed to conditionally modify text.

• Manage Entries: Manage search and replace strings in a list, and enable or disable entries for replacement, highlighting or searching within the list.
• Highlighting: Highlight multiple find words in unique colors for better visual distinction, with over 20 distinct colors available.
• Character Limit: Field limits of 4096 characters for "Find what:" and "Replace with:" fields.

• Supports import/export of search and replace strings with their options in CSV format, including selection states.
• Adherence to RFC 4180 standards for CSV, enabling compatibility and easy interaction with other CSV handling tools.
• Enables reuse of search and replace operations across sessions and projects.

• Exports Find and Replace strings into a runnable script, aiming to encapsulate the full functionality of the plugin in the script. However, due to differences in tooling, complete compatibility cannot be guaranteed.
• This feature intentionally does not support the value \0 in the Extended Option to avoid escalating environment tooling requirements.

The MultiReplace plugin offers a multilingual UI, enabling navigation in various languages through adjustments in the languages.ini file within the plugin's configuration directory:

• %APPDATA%\Notepad++\plugins\config\MultiReplace\languages.ini

This file enables users to select or customize the UI language settings, enhancing the accessibility and usability of the plugin for non-English speakers.
