Number Range Expression Syntax¶
EmEditor allows you to use number range expressions as search expressions.
To use a number range in Find, Replace, Find in Files, Replace in Files, or Advanced Filter dialog box select Number Range from the Mode drop-down list box.
To use a number range in Find, Replace, FindInFiles, ReplaceInFiles, or Filter methods of macros, include the eeExFindNumberRange flag to the ExFlags parameter.
A number range is expressed as an interval notation. A bracket indicates an included endpoint, and a parenthesis indicates an excluded endpoint. If both numbers do not include a decimal point, the method matches only integers. Minimum and/or maximum number may be omitted to mean negative and/or positive infinity. The number format depends on the locale specified in the Locale drop-down list box in the Sort page of the Customize dialog box. In some locales (such as German), a comma (',') is used to denote a decimal point, and in that case, a space before and after the separator comma is necessary to avoid ambiguity.
As of v19.6, a number range can specify a set of numbers with a specified increment. An increment can be specified as the third parameter "c" in [a , b , c] or (a , b , c).
For instance,
Number Range | Meaning |
|---|---|
[1 , 9] | matches integers 1, 2, 3, ..., 9. |
[ , 9) | matches any integers less than 9. |
[1.0 , 9.0) | matches decimal numbers greater than or equal to 1.0, and less than 9.0. |
[ , 1.0) | matches any decimal numbers less than 1.0 |
(2.0 , ] | matches any decimal number greater than 2.0 |
[1,0 , 9,0 "," ] | matches decimal numbers greater than or equal to 1.0, and less than 9.0 using a comma as a decimal point. |
[1 , 9 , 2] | matches integers 1, 3, 5, 7, 9. |
[1.0.0.0 , 1.255.255.255] | matches IPv4 addresses 1.0.0.0 ... 1.255.255.255. |
1.1.1.1/8 | matches IPv4 addresses 1.0.0.0 ... 1.255.255.255. |
2001:db8::/48 | matches IPv6 addresses 2001:db8:: ... 2001:db8:0:ffff:ffff:ffff:ffff:ffff. |
[1/1/2021 , 12/31/2022] | matches dates 1/1/2021 ... 12/31/2022. |
[1/1/2021 , 12/31/2022 "M/d/yyyy" ] | matches dates 1/1/2021 ... 12/31/2022 using the "M/d/yyyy" format. |
[13:00:00 , 18:59:59 "HH:mm:ss" ] | matches times 13:00:00 ... 18:59:59 using the "HH:mm:ss" format. |
[2021-01-01 00:00:00 , 2022-12-31 23:59:59 "yyyy-MM-dd HH:mm:ss" ] | matches dates and times 2021-01-01 00:00:00 |
Date and Time formats¶
The following formats can be used to make date and/or time formats.
Format | Meaning |
|---|---|
yy | Year represented only by the last two digits. |
yyyy | Year represented by four digits. |
M | Month as digits without leading zeros for single-digit months. |
MM | Month as digits with leading zeros for single-digit months. |
MMM | Abbreviated month name, for example, "Nov" in English. This format may not be available if the current locale does not provide month names. |
MMMM | Month name, for example, "November" for English, and "Noviembre" for Spanish. This format may not be available if the current locale does not provide month names. |
d | Day of the month as digits without leading zeros for single-digit days. |
dd | Day of the month as digits with leading zeros for single-digit days. |
HH:mm | Hours and minutes separated by a colon; 24-hour clock. |
HH:mm:ss | Hours, minutes and seconds separated by a colon; 24-hour clock. |
| | Or. Use this to combine multiple formats, allowing the number range expression to match either formats. |
