Working with EditPlus Text Editor-Regular Expression How To

Editplus is a lot better than the regular text editor, Notepad.
From all it’s features I like RegExp Support the most, and than comes the block select feature.
Here are the quick lines to carry out regular tasks using regular expression in Editplus. It’s kinda downloadable cheetsheet list.

Remove all empty lines:

Find: “^\n” (Ignore double-quotes in all find/replace)
Replace: “”
Where,
^ – Beginning of the line
\n – New Line

Remove Multiple Spaces convert into single space:

Find: ” +”
Replace: ” “
Where,
+ – find one or more occurance of space character.

Comment multiple line of code:

Find: “^”
Replace: “#” or “//”
You may optionally use: Edit Menu > Format > Line Comment.
Generate Comma Separated List from new line delimited list:

Find: “\n”
Replace: “, “
This helps in even joining some of lines of code instead of replacing by comma you may replace it with “”.

Manipulate columns display order / punctuation:

Find: “([0-9]+)\t([a-zA-Z]+)”
Replace: “\2\t\1”
Where,
[0-9]+ – Finds one or more digits
[a-zA-Z]+ – Finds one or more characters
() – mark the block or capture the group
\2 – 2nd mark expression
Eg:
123 abc
345 cde
567 efg
Becomes:
abc 123
cde 345
efg 567
The Other Way:
– Press Alt+C
– Drag you mouse to select respective column and click
– Copy / Cut as required

[ad#ad-2-300×250]

Append / Add semicolon (any character) at the end of the line:

Find: “\n”
Replace: “;\n”

Enclose lines by quotes:

Find: “\n”
Replace: “‘\n'”

Delete all lines containing a given STRING:

Find: “^.*STRING.*$”
Replace: “”

Remove lines not containing a given STRING:

I don’t know how to do this!! 🙂

Convert tab separated file into insert statements:

TSV: abcd de4 iirn 34399
SQL: INSERT INTO TABLENAME VALUES (“abcd”, “de4”, “iirn”,”34399″);
Find: “(.*)\t(.*)\t(.*)\t(.*)”
Replace: “INSERT INTO TABLENAME VALUES (“\1”, “\2”, “\3″,”\4″);”

Format the telephone number:

Find: “([0-9][0-9][0-9])([0-9][0-9][0-9])([0-9].*)”
Replace: “\1-\2-\3”
Eg.:

Original: 1231231231
Formatted-1: 123-123-1231

Remove Brackets:

Find: “\(|\)”
Replace: “”
Where,
\( – Match (. \ is required to escape marking the expression.
| – or

Replace 1st occurrence of character:

Find: ” (.*)”
Replace: “-\1”
Where,
(.*) – matches everything and marks the block
** Make sure you ignore double-quotes(“) while writing in find / replace boxes.
