[New Plugin] MultiReplace

[Thomas Knoefel]

@Coises Wow, you’re always full of good ideas! :-) Thanks! I hope I can share some of mine with you too. :-))

[Thomas Knoefel]

The first functional release is now available for testing and can be downloaded here.

While I’ve made some changes from the original concept, it still closely aligns with that initial vision. This Dynamic Substitution is compatible with all search settings of Search Mode, Scope, and the other options.

By activating the 'Use Variables’ checkbox, variables associated with specified strings can be employed, allowing for conditional and computational operations within the replacement string.

Variables Overview

Variable	Description
CNT	Count of the detected string.
LINE	Line number where the string is found.
APOS	Absolute character position in the document.
LPOS	Relative line position.
COL	Column number where the string was found (CSV-Scope option selected).
CAP1, CAP2, …	Correspond to capture groups $1, $2, … in regex patterns. They can be used for calculations or as strings.
	Note: Both dot and comma can be used as decimal separators in Capture Variables but thousands separators are not supported.

Command Overview

String Composition

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

set(strOrCalc)

Outputs strings or numbers directly.

Example	Result (assuming LINE = 5, CNT = 3)
set("replaceString"..CNT)	“replaceString3”
set(LINE+5)	“10”

cond(cond, trueVal, [falseVal])

Implements if-then-else logic, or if-then if falseVal is omitted.

Example	Result (assuming LINE = 5)
cond(LINE<=5 or LINE>=9, "edge", "center")	“edge”
cond(LINE<3, "Modify this line")	(Original text remains unchanged)
cond(LINE<10, cond(LINE<5, cond(LINE>2, "3-4", "0-2"), "5-9"), "10+")	“5-9” (Nested condition)

fmtN(num, maxDecimals, fixedDecimals)

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.

Example	Result
set(fmtN(5.73652, 2, true))	“5.74”
set(fmtN(5.0, 2, true))	“5.00”
set(fmtN(5.73652, 4, false))	“5.7365”
set(fmtN(5.0, 4, false))	“5”

Operators

Type	Operators
Arithmetic	+, -, *, /, ^, %
Relational	==, ~=, <, >, <=, >=
Logical	and, or, not

Engine Overview

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

I have incorporated two additional variables which I find beneficial:

• LCNT: Count of the detected string within the line.
• MATCH: Contains the text of the detected string, in contrast to CAP variables.

The complete documentation can be found here.

Should anyone have ideas for additional variables that are missing and should be included into this option, feel free to share.

Below are some examples demonstrating how to utilize the “Use Variables” option.

Find in:	Replace with:	Description/Expected Output	Regex	Scope CSV
;	cond(LCNT==5,";Column5;")	Adds a 5th Column for each line into a ; delimited file.	No	No
(\d+)	set("$1€ 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))	E.g., 1.0.0 is aligned left, 1.2.0 is prefixed with a space, shifting right, 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)), "*", " ")	“For the fun part ;-)” Draws a sine wave across a canvas of ‘-’ characters spanning at least 20 lines and 80 characters per line.	No	No

After intensive testing, Release 2.0.07 is complete and is shipped with the new Notepad++ release 8.5.8.

New Functionalities:

• CSV Syntax Highlighting: Provides visual formatting to delimited files, aiding in the readability and structure recognition of the data.

• CSV Column Scope: Allows specific column targeting for search and replace in any delimited files.

• Rectangular and Multi-selections Support: Extends search and replace to specified rectangular or multi-selected areas.

• Conditional and Computational Functionality via “Use Variables” Option: Enables dynamic replacement strings using variables for conditional and computational operations, facilitated by simple set and cond commands.

I’ve noticed that the latest archives (e.g. MultiReplace-v2.0.0.7-x64.zip and MultiReplace-v2.0.0.7-Win32.zip) contain pretty old README.md that does not mention all the amazing new features.

And it could be a good idea to add some kind of interactive help. Maybe in a form of popup hints or maybe as a clickable [?] button that allows to “apply” the ‘?’ sign to an UI element by showing the corresponding help text when applied.

Ah, now that you mention it, I realize I updated the README after the release, which was an oversight on my part. Thanks for catching that. There’s a new release coming with the next N++ version, which will introduce “Replace in all open documents”. I’ll make sure to get the order right.then.

Thanks for the suggestion. My initial idea on that is to add a Question Mark Button next to ‘Use Variables’. This would launch a small help window with different sections like Commands, Options, Operators, Math Functions, and String Functions. Each section would be foldable and offer a description of each list entry. Clicking on a specific entry would insert its function at the cursor position in the Replace String Section.

The next MultiReplace release 2.1.0.8 will be shipped with the next Notepad++ version 8.5.9

These are the release notes:

• Added feature: “Replace All across all open documents”.
• Enhancement: Added tooltips to column headers in lists.
• Optimization: Removed “Normal” column due to redundant information.
• Bug fix: Resolved issue with “Extended” in combination with “Use Variables.”

[Thomas Knoefel]

I wish you all a Happy New Year.!

The next MultiReplace 2.2.0.9 version will be shipped with Notepad++ 8.6.1 or can be dowloaded here.

Release Notes for 2.2.0.9:

• “Replace first match only” checkbox: I’ve noticed that this option will be occasionally used, especially when replacing strings with the same find pattern in a list, but with different replace strings. Although achievable by the ‘Use Variables’ option using cond(CNT==1,‘Replace String’).

• Help Button for 'Use Variables’: A new help button, is now included on the panel.
  A big thanks from here to @Coises Coises, the creator of the Columns++ Plugin, providing the template for the HTML help page.

• Enhancement in ‘Use Variables’ with init({}): This feature is closing the gap for self-defined variables. These Variables are integrated into the entire Replace-All process and across all list run replacements.

The init command introduces a way to initialize newly defined variables, ensuring the value is set just once. With this, the newly introduced if-Then feature becomes significantly more useful, especially when combined with other available variables.

1st example:
It is summing digits of Column2 and Column4 and Replaces the 4th found digit in the line:
Find: (\d+)
Replace: init({COL2=0,COL4=0}); cond(LCNT==4, COL2+COL4); if COL==2 then COL2=CAP1 end; if COL==4 then COL4=CAP1 end;

Output:
1,20,text,2,0 -> 1,20,text,2,22.0

2nd example:
Removes duplicate lines, keeping the first occurrence of each line. Like discussed in this Post.
Find: ^(.*)$
Replace: init({MATCH_PREV=1}); cond(MATCH == MATCH_PREV, ''); MATCH_PREV=MATCH;

I want to announce the new MultiReplace release 2.3.0.10, bringing new CSV features in Notepad 8.6.3.

Here’s what’s new:

• Sorting Lines in CSV by Columns: Ascend or descend, combining columns in any prioritized order.
• Deleting Multiple Columns: Simultaneously remove various columns, cleaning up any obsolete delimiters.
• Clipboard Column Copying: Instantly copy columns, complete with original delimiters, into the clipboard.

Header Line Sorting Control:

The header line is excluded from sorting by default, as shown in the demo. To alter the number of excluded lines, change HeaderLines=1 to your desired count in [userdir]\AppData\Roaming\Notepad++\plugins\config\MultiReplace.ini.

Regex Assistance for Numeric Sorting:

To prepare numbers for lexicographical sorting and later remove the added leading zeros, you may use the following regex patterns:

Purpose	Find Pattern	Replace With
Align Numbers with Leading Zeros (Decimal)	\b(\d*)\.(\d{2})	set(string.rep("0",9-string.len(string.format("%.2f", CAP1)))..string.format("%.2f", CAP1))
Align Numbers with Leading Zeros (Non-decimal)	\b(\d+)	set(string.rep("0",9-string.len(CAP1))..CAP1)
Remove Leading Zeros (Decimal)	\b0+(\d*\.\d+)	$1
Remove Leading Zeros (Non-decimal)	\b0+(\d*)	$1

Required Settings:

• For “Align Numbers with Leading Zeros” operations:
  • Enable ‘Regex’
  • Enable ‘Use Variables’
• For “Remove Leading Zeros” operations:
  • Enable ‘Regex’
