Lines tools
Indent (Ctrl+Tab)
Indents each line
of the selection with a Tab character. Does not modify empty lines
.
Note: Indents with spaces instead of a Tab, if Insert spaces instead of Tab setting is turned on. The number of spaces inserted can be specified thru Tab Size setting. See chapter Edit page of the Settings dialog for more details.
Note: If Tab key indents multiple lines setting is turned on, this tool can be invoked thru simple Tab key (as long as multiple lines are selected of course).
Note: The selection always persists in this tool.
| if (IsNonEmpty (line)) Indent (line); |
| if (IsNonEmpty (line)) Indent (line); |
See also Unindent Lines, Quote Lines and Tabify tools.
Unindent (Ctrl+Shift+Tab)
Removes the first character on each line
of the selection, if that character is a white-space
.
Note: This tool does not remove anything else but white-spaces
.
Note: If Insert spaces instead of Tab setting is turned on, this tool may unindent as many spaces as the Tab Size setting specifies, making it the counterpart to the Indent Lines tool.
Note: If Tab key indents multiple lines setting is turned on, this tool can be invoked thru simple Shift+Tab key (as long as multiple lines are selected of course).
Note: The selection always persists in this tool.

Quote.. (Alt+Ctrl+Q)
Asks for a Quote phrase to work with and then quotes (i.e. indents) the selection with the specified phrase at the beginning of each line
.
Optionally, Quote non-empty lines only can be used to quote non-empty lines
only, which ensures that empty lines
are not modified at all.
Optionally, using the Skip leading spaces, the quoting phrase may be inserted just after all leading white-spaces
on each line. This way, any current line indentation is kept unmodified, and the quoting phrase is appended to that indentation, before the first graph
(i.e. non-white-space
) character.
Note: When quoting of empty lines
is allowed, and leading white-spaces
are to be skipped, special consequential case occurs. On empty lines
, quoting phrase is appended, because the skipped leading white-spaces
is all that those line contain.
Note: The selection always persists in this tool.

Tip: Combine the Quote Lines tool with the Close Lines tool in order to write paragraphs or lists in HTML documents without having to bother with <p> or <li> tags while writing. Write all paragraphs first, each one on a separate line (you may use Word Wrap (hotkey Ctrl+W) to see long lines automatically wrapped into several lines, since the Word Wrap does not affect tools). When done, select all the lines and use both Quote Lines and Close Lines tools to add the <p> and </p> tags (or <li> and </li> tags) to each line.

Unquote (Ctrl+Shift+Q)
Takes the very first character of the selection as a quoting character. Then removes the first character on each line
of the selection, if that character is the quoting character.
Note: This is very similar to the Unindent Lines tool, but it is not white-space
-oriented only, and thus can be used to remove any common character from the beginning of lines.
Note: The selection always persists in this tool.
| One Ring to rule them all, One Ring to find them, |
| ne Ring to rule them all, ne Ring to find them, |
See also Quote Lines, Unindent Lines and Shift Lines Left tools.

Shift Left (Alt+Ctrl+Shift+Q)
Removes the first character from each line
of the selection, no matter what that character is.
Note: Tabs are treated as single characters.
Note: The selection always persists in this tool.
| One Ring to bring them all and in the darkness bind them. |
| ne Ring o bring them all nd in the darkness ind them. |

Close.. (Alt+Ctrl+C)
Asks for a Close phrase to work with and then closes each line
of the selection with the specified phrase, i.e. appends the specified phrase to each line
.
Optionally, Close non-empty lines only can be used to close non-empty lines
only, which ensures that empty lines
are not modified at all.
Optionally, using the Skip tail spaces, the closing phrase may be inserted just before all tail white-spaces
on each line. This way, any current end-of-line white-spaces
are kept unmodified, and the closing phrase is prepended to those white-spaces
, after the last graph
(i.e. non-white-space
) character.
Note: When closing of empty lines
is allowed, and tail white-spaces
are to be skipped, special consequential case occurs. On empty lines
, closing phrase is prepended, because tail white-spaces
is all that those line contain.
Note: The selection always persists in this tool.

Unclose (Ctrl+Shift+C)
Takes the very last character of the first line of the selection as a closing character. Then removes the last character on each line
of the selection, if that character is the closing character.
Note: This is very similar to the Trim Tail Spaces tool, but it is not white-space
-oriented only, and thus can be used to remove any common character from the end of lines.
Note: The selection always persists in this tool.

Shift Right (Alt+Ctrl+Shift+C)
Removes the last character from each line
of the selection, no matter what that character is.

Tabify (Ctrl+Shift+O)
Tabifies the indentation of the selection by replacing groups of leading white-spaces
with Tabs on each line
according to the current Tab Size setting. See chapter Edit page of the Settings dialog for more details.
If Tabs and Spaces are mixed together on the beginning of a line, the total visual white-space
extent is calculated first, and only then Tabs (and Spaces) are used to fill the space of the original indentation. Note that Tabs always take precedence over Spaces while filling the indentation, i.e. Spaces are used only if necessary (where another Tab would overflow the original extent of the indentation).
Note: Using this tool should not generate any visible changes to the indentation, when used with a fixed-width font. However, some proportional fonts do not use the average character width for Spaces, thus Tabs may seem to be longer than a set of Spaces. This is a visual inconvenience only and should not be considered incorrect.
Note: This tool does not modify any other white-spaces
than the leading ones.
See also Untabify tool.
Untabify (Alt+Ctrl+O)
Untabifies the indentation of the selection by replacing leading Tabs with Spaces on each line
according to the current Tab Size setting. See chapter Edit page of the Settings dialog for more details.

Remove Empty (Ctrl+Shift+V)
Removes all empty lines
from the selection.
Note: Does not modify non-empty lines
.
| One little, two little, three little Indians. |
| One little, two little, three little Indians. |
See also Collapse Empty Lines tool.
Collapse Empty (Alt+Ctrl+Shift+V)
Collapses all sequences of empty lines
in the selection. While collapsing, each continuous sequence of empty lines
is reduced to only one line, leaving the first of those lines intact, and removing all following empty lines
.
Note: Does not modify non-empty lines
.
| One little, two little, three little Indians. |
| One little, two little, three little Indians. |
See also Remove Empty Lines tool.
Unique (Ctrl+Shift+X)
Searches the selection for duplicate lines
and removes all duplicates. The order of the uniqued lines
remains unchanged and from each two equal lines, the second one is removed.
Note: Use Alt+Ctrl+Shift+X hotkey to ignore case
while searching for duplicate lines
.
Note: This tool is actually a shortcut to the Find Duplicates tool, which allows to specify more options on how to search for duplicate lines.
| how much wood would a woodchuck chuck if a woodchuck could chuck wood |
| how much wood would a woodchuck chuck if could |
See also Find Duplicates tool.
Find duplicates.. (Alt+Ctrl+X)
Searches the selection for duplicate lines
. Then either counts and/or removes duplicates, or removes unique lines, depending on following options and choices:
- All lines (remove duplicates) - Removes all duplicate
lines
, keeping exactly one instance of each original line. The order of resultinglines
remains unchanged and from each two equal lines, the second one is removed. This is identical to the behavior of the Unique Lines tool. - Unique lines only - Removes all
lines
that have duplicates, leaving only thoselines
that were already unique. The order of resultinglines
remains unchanged. - Duplicated lines only - Removes all
lines
that do not have duplicates, leaving only thoselines
that do have duplicates. The resultinglines
are uniqued in the process, thus each resultingline
appears only once in the results. The order of resultinglines
remains unchanged.
Optionally, if the Count duplicates option is checked, the tool counts number of duplicates of each line
and adds these numbers to the results. Each resulting line then contains a number of its duplicates, written in brackets, in front of that line.
Additionally, Leave empty lines option may be specified to spare all empty lines
from being removed, counted or otherwise modified. This can, for example, prevent unwanted paragraph
joining. If this option is not specified, even empty lines get counted and/or removed, which might not be always desired.
And finally, Ignore case option may be specified to ignore case
when matching duplicates.
| how much wood would a woodchuck chuck if a woodchuck could chuck wood |
| wood a woodchuck chuck |
| (1) how much (2) wood (1) would (2) a woodchuck (2) chuck (1) if (1) could |
See also Unique Lines tool.
Columns, Numbers... (Alt+Ctrl+Y)
Cuts portions of lines
from the selection and replaces the old lines
with new generated lines
according to given Output mask. The Output mask may contain any text, which is duplicated to every new generated line, and may include these special variables, which are computed on the fly and have the following purpose:
- %0 — inserts a copy of the entire original line.
- %1 - %9 — inserts a line portion, cut from the original line according to rules specified in corresponding tab. See below.
- %d — inserts a decimal number from the Counter. See below.
- %x — inserts a lower case hexadecimal number from the Counter. See below.
- %X — inserts an upper case hexadecimal number from the Counter. See below.
- %b — inserts a binary number from the Counter. See below.
- %o — inserts an octal number from the Counter. See below.
- %r — inserts a random number from the Random number generator. See below.
- %l0 — inserts length, in characters, of the original line.
- %l1 - %l9 — inserts length of a line portion, cut from the original line according to rules specified in corresponding tab. See below.
- %n — inserts a newline. Note: This variable results in generating sequence of multiple lines for each of the input lines.
- %% — inserts a single % character. Note: Since % character is used to prefix variables, doubled %% must be used in order to place plain % into the results. Note: Using a simple % character, not followed by a recognized variable, is considered an error in the Output mask to prevent possible inconvenience from future improvements of the tool.. ;)
All variables (except %n) may be supplied an aligning specifier. Aligning specifier must appear directly after the % prefix character. It is used to align values of the variable into a neat fixed-width column. Width of such column is determined by examining the variable for all lines and taking the longest length. Aligning specifier may be one of the following:
- < — aligns the variable to the left, using spaces to fill the shorter lines from right.
- ! — aligns the variable to the center, using spaces to fill the shorter lines from both sides.
- > — aligns the variable to the right, using spaces to fill the shorter lines from left.
- + — aligns the variable to the right, using zeros to fill the shorter lines from left.
Note: Aligning a variable into a fixed-width column does not necessarily guarantee a neat visual column in the results. There are two reasons for having the column scattered in the results:
- If proportional font is used for text displaying, it may render different characters with different extents, resulting in different visual positions of respective character positions.
- If multiple variables are used in the Output mask, all of them should include an aligning specifier to ensure nothing else but neat aligned columns in the results. This is because variable alignment is computed separately for each variable, and is thus insensitive to other portions of currently generated line. Therefore, if one variable results in a non-fixed-width column, there is no guaranteed way to ensure further visual column alignment (although variables themselves would continue to get aligned neatly into their own private columns).
Some variables require a Counter to be defined. The tool uses Start number to initialize the Counter before processing the selection. Then, for each line of the selection, increments the Counter by a Step.
Note: Counter always produces the same number for the same line, even if used multiple times per line.
Some variables require a Random number generator. The generator produces decimal numbers between Min and Max (inclusive) every time a variable requires a random number.
Note: Unlike Counter, Random number generator produces a different number each time it is used, even if used multiple times for the same line.
Note: Random number generator expects the Min to be less than Max. If Min is greater or equal to Max, numbers between 0 and 4294967295 are generated.
Warning: Although the tool uses a more complex pseudo-random generator (than a linear congruential generator), it is not safe to assume that the generator is cryptographically secure. This tool should not be used for encryption purposes if real sturdy protection is expected, since the pseudo-random generator is not constructed to withstand real cryptanalysis. It is only safe to assume that the generator is not easily predictable without advanced cryptanalysis — which is acceptable for most common tasks.
Optionally, Modify non-empty lines only can be used to keep all empty lines
intact by this tool.
Note: The Preview option can be used to toggle on/off Preview pane. Preview pane shows a small portion of lines transformed by values currently set in the tool dialog. Be aware that preview is always generated from the current selection. If there is no selection, then there is nothing to preview. Also, since only a small portion of the selection is used for preview, alignment of columns is computed for that portion only (excluding the rest of the selection), which may result in shorter lines.
Cutting line portion
Cutting portion of a line
is divided into two successive parts. First, columns
are cut from the line
, by either:
- Entire line, which keeps the entire original
line
. - Columns, which allows to specify one or more subsequent
columns
between columns from and columns to (inclusive). Individualcolumns
are separated by characters from Delimiting characters, which means that theline
is scanned for thesedelimiting characters
, and wherever adelimiting character
is found (any character from Delimiting characters), oldcolumn
ends before thisdelimiter
and a newcolumn
begins after thisdelimiter
. There can be as manydelimiting characters
as necessary and all of them delimitcolumns
equally and indiscriminately.- Optionally, Delimit by entire phrase rather than separate characters can be used to stop treating Delimiting characters as a set of individual characters, and scan for an entire
delimiting phrase
instead. - Optionally, Treat any sequence of delimiters as single delimiter can be used to count several successive
delimiters
as a singledelimiter
. This can be useful, for example, if inputcolumns
are aligned by spaces into neat visual columns, where each twocolumns
are delimited by an arbitrary-length sequence of spaces. Such sequences need to be treated as indivisible columndelimiters
.- Note that even different delimiting characters are treated as a single indivisible
delimiter
, if found in sequence.
- Note that even different delimiting characters are treated as a single indivisible
- Optionally, Calculate columns backwards: from right to left can be used to numerate the
columns
from the end of line rather than the usual way. Note, however, that this only affects how thecolumns
are numbered before they are cut; the text of thecolumns
is not reversed. - Note:
Delimiters
are not included within thecolumn
being cut. However, if two or more subsequentcolumns
are cut together, innerdelimiters
are not removed and become part of the line portion being cut. - Note: Delimiting characters are always
case sensitive
. - Examples: A line HELLO WORLD would be divided into:
- two columns (HELLO and WORLD) — if delimited by a Space character;
- four columns (H, LL, W and RLD) — if delimited by a set of EO characters;
- four columns (HE, {empty}, O WOR and D) — if delimited by an L character;
- but only three columns (HE, O WOR and D) — if Treat any sequence of delimiters as single delimiter option is turned on;
- and only one column (HELLO WORLD) — if delimited by an X character,
lower case
e character, or if delimited by no characters — this is because none of these characters are found on the examined line.
- Optionally, Delimit by entire phrase rather than separate characters can be used to stop treating Delimiting characters as a set of individual characters, and scan for an entire
Note: Columns
are cut for each line separately, therefore the total number of columns
on a line may vary from line to line. If specified column
number is beyond the total number of columns
, empty zero-length portion is cut for such column
from that line. Therefore, it is allowed to cut columns
2-7, even though some lines do not have enough columns
to offer.
After the first part (cutting columns
from the line), the resulting portion of the line can be further cropped by turning Use only characters option on, and specifying a range of character positions between from position and to position. This cuts off everyting before the from position and everyting after the to position.
- Calculate the position backwards: from right to left can be used to numerate the character positions from the end of line rather than the usual way. Note, however, that this only affects how the positions are numbered before they are cropped; the text itself is not reversed.
Note: Range of character positions is always cropped after columns
are cut. If a range is specified beyond currently cut columns
, empty zero-length portion is cropped from that line, even if the original line continues after the cut columns
. In other words, range of character positions cannot bring back what has already been cut off by previous step.
Note: There is currently no way to cut columns
after cropping a range of character positions.
Note: Column preview button displays a small portion of lines transformed by current dialog values. Be aware that preview is always generated from the current selection. If there is no selection, then there is nothing to preview.
Examples
In the examples below, we use the following input text:
| No;Name;Race;Age 1;Amy;labrador;4 2;Konie;bordercollie;3 3;Kvido;mongrel;2 |
Simple numbering
Example of a simple numbering Output mask: %+d, %1. This mask will cut a line portion (specified for variable %1) from each line and place it in the results after a decimal number, colon and a space. The numbers will be neatly aligned to the right by leading zeroes where necessary, in order to have the same count of digits.
| 1, Race 2, labrador 3, bordercollie 4, mongrel |
Columnizing trick
Example of a columnizing Output mask: %<1 | %2. If variable %1 cuts the first line column, and the variable %2 cuts the rest of the line, this mask can be used to visually columnize the list from the example above. This is done by aligning the variable %1 (the first column) to the left, adding a glue like | , and then appending the rest of the line. However, since this would columnize the first column only, one needs to invoke this tool several times in a row, until all columns are transformed. The main reason to do it this way is that it can columnize quite many columns very quickly once this is set up correctly.
Note: Make sure not to use the same delimiter for new columns that is used for old columns. Doing so would result in columnizing the first column over and over again. The main idea in this trick is to make the tool work subsequently thru all old columns, converting them into new columns one by one. The tool may not be allowed to confuse new and old columns, or it won't pan out. In this example, old columns are delimited by ; while new columns are delimited by | , which is mutually exclusive as required.
| No | Name | Race | Age 1 | Amy | labrador | 4 2 | Konie | bordercollie | 3 3 | Kvido | mongrel | 2 |
Note: The example above only works for aligning to the left. To align to the right, columnizing backwards must be applied, from the last column to the first (i.e. the principle of working thru columns must be reversed). There is no way to center the columns this way (though one can always cut each column separately into a different variable and then specify a mask, which enumerates all the variables).
Tip: Persistent selection setting might come handy for this technique. See chapter Tools page of the Settings dialog for more details.
Grep, Filter by Pattern.. (Alt+Ctrl+P)
grep is a command-line utility for searching plain-text for lines that match a regular expression.
Its name comes from the ed command g/re/p, which has the same effect: doing a global search with the regular expression and printing all matching lines.
Wikipedia
Searches for a given Find phrase within the selection.
It can then either filter out all non-matching lines
,
or alternatively filter out all matching lines
.
Regular expressions can be used as the Find search pattern.
Choose Objective of the filtering
The Keep matching lines option keeps all matching lines
and removes any non-matching lines
.
The Remove matching lines option removes all matching lines
and keeps any non-matching lines
.
The Also keep empty lines option can be used to also keep any empty lines
on top of matching lines
. This option is only available with Keep matching lines.
The Only matched parts of lines option
- can be used to keep only those parts of the matching
lines
that matched the Find (with Keep matching lines); or - can be used to remove only those parts of the matching
lines
that matched the Find (with Remove matching lines).
The Add line numbers option can be used to add the original line numbers to the results. Note that these line numbers are counted from the beginning of the selection the tool is used on.
Add Context of extra lines
The Extra lines before and Extra lines after fields can be used to specify extra lines to be considered as part of the match when keeping or removing the matching or non-matching lines
. Specifically,
- with Keep matching lines, extra lines before and/or after are kept;
- with Remove matching lines, extra lines before and/or after are removed.
Note: Context before or after is not available with Only matched parts of lines turned on.
Note: With Also keep empty lines, those empty lines
are not considered matching simply by being empty lines
. The are kept for convenience, but do not by themselves add any Context. Only lines matched via the Find phrase, empty of not, trigger adding Context.
More Options on searching
By default, the search is case insensitive
. The Match case option can be used to make the search case sensitive
.
The Whole words option can be used to restrict the search to only those matches, which start and end at word boundaries. Note that a match itself might contain non-word characters
, since only the boundaries of the match are probed. Therefore, the last character before the match and the first character after the match may not be word characters
; while the first character and the last character of the match must be word characters
.
The Whole lines option can be used to restrict the search to only those matches, which start at a line beginning and end at a line end. Note that a match itself might contain a newline
, since only the boundaries of the match are probed.
The Escapes option can be used to allow entering newlines and Tab characters into the Find phrase. Use \n sequence to encode a newline, use \t to encode a Tab character, and use \\ to encode a simple backslash (\) character wherever a confusion with other escapes could arise.
Note: A newline escape (\n) matches any kind of newline (Windows, Unix, Mac). A newline escape matches exactly one newline, i.e. use \n\n in order to match two consecutive newlines, etc.
The RegExps option can be used to turn the Regular expressions engine on. When Regular expressions are enabled, Find is parsed as a regular expression pattern. See chapter Regular expressions for more details on supported regular expressions syntax.
Note: Invalid or faulty regular expression patterns result in tool refusing to work until the pattern is corrected.
Further notes
Note: Search patterns are limited to 64 KiB. Prior to version 6.3, search patterns were limited to 8 KiB.
Note: The tool posts Total matches
to the Status Bar.
This number may be different than the number of resulting lines, if multiple matches are found per line.
