RegEx Negative Look Behind with Sublime

April 30, 2018 / / 0 Comments

Negative look behind with regex is another useful constraint that we can add to our expression. It only matches the right side, if and only if the look behind doesn't match. The look behind doesn’t consume any characters and has the following syntax:

(?<!<look behind>)<right side>

Example:

<?xml version="1.0"?>
<fruits>
 <a>apple</a>
 <b></b>
 <c>cashew</c>
 <d></d>
</fruits>

From the XML above find all the empty elements and add an attribute empty that is set to true but only matching the opening tag.

Find Replace Comment
(?<!^<)<(?<tag>\w*[^>])>(?=<) <$1 empty=”true”> The negative <look behind> is the one highlighted in blue.

The <right side> is the one highlighted in green.

RegEx Negative Look Ahead with Sublime

 <d></d>
</fruits>

From the XML above find all the empty elements and add an attribute empty that is set to true but only matching the opening tag.

Configuring User Level Proxy for Gradle

April 26, 2018 / / 0 Comments
  1. Create gradle.properties files in the following directory if not yet existing: 
     <USER_HOME>/.gradle
  2. Add the following entries for http proxy configuration in the gradle.properties file: 
    systemProp.http.proxyHost=<PROXY_HOST>
systemProp.http.proxyPort=<PROXY_PORT>
systemProp.http.proxyUser=<PROXY_USERNAME>
systemProp.http.proxyPassword=<PROXY_PASSWORD>
systemProp.http.nonProxyHosts=<NON_PROXY_HOSTS>

    Note: <NON_PROXY_HOSTS> is delimited by pipe symbol (e.g. localhost|*.test.net)

    Note: If https proxy configuration is needed use the same entries except that all http will must be replaced with https (e.g. systemProp.https.proxyHost).

RegEx Named Groups with Sublime

April 24, 2018 / / 0 Comments

Parentheses in regular expression (RegEx) can be used for grouping expression and can be named. To name it, after the opening parenthesis follows it with the following:

 ?<name>

Within the same expression you can backreference the group using the following:

\k<name>

On the replace field, based on the group position it will be numbered starting from 1 and increasing from the left of the expression and must be preceded with dollar sign (i.e. $). Use this number to access the captured match.

Note: if your group exceeds a single digit use ${<nn>} (e.g. ${10}) notation.

Example

<?xml version="1.0"?>
<fruits>
 <a>apple</a>
 <b></b>
 <c>cashew</c>
 <d></d>
</fruits>

From the XML above find all the empty elements and add an attribute empty that is set to true.

Find Replace Comment
<(?<tag>\w*[^>])></\k<tag>> <$1 empty="true"></$1> The named group (i.e. blue text) is assigned to $1.

The \k<tag> (i.e. green text) is the backreference.

RegEx Capturing Groups with Sublime

April 23, 2018 / / 0 Comments

Parentheses in regular expression (RegEx) can be used for grouping expression.

Within the same expression you can backreference the group using the following:

\<GROUP_POSITION>

<GROUP_POSITION> is the quantitative location of the group from left to right starting from 1.

On the replace field, it follows the <GROUP_POSITION> but instead of using backslash (i.e. \) use dollar sign (i.e. $) to precedes it.

Note: if your group exceeds a single digit use ${<nn>} (e.g. ${10}) notation.

Example

<?xml version="1.0"?>
<fruits>
 <a>apple</a>
 <b></b>
 <c>cashew</c>
 <d></d>
</fruits>

From the XML above find all the empty elements and add an attribute empty that is set to true.

Find Replace Comment
<(\w*[^>])></\1> <$1 empty="true"></$1> The group (i.e. blue text) is assigned to $1.

The \1 (i.e. green text) is the backreference.
