 Retrieve the path configuration C<VARIABLE>. The return value
 is an expanded path or C<undef> if it's not defined.

 Retrieve the integer configuration C<VARIABLE>. The return value
 by 1024, 1048576 (1024^2), or 1073741824 (1024^3) prior to output.
 It would return C<undef> if configuration variable is not defined,

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
