Delete project files¤

Removes file resources from the project based on a regular expression (regex).

The project-relative path of each file of the current project is tested against a user given regular expression and the file is deleted if the expression matches this name. The file names include the sub-directory structure if present but do not start with a /. The regular expression has to match the full path of the file and is case sensitive.

Given this list of example files of a project:

dataset.csv
my-dataset.xml
json/example.json
json/example_new.json
json/data.xml

Here are some regular expressions with the expected result:

  • The regex dataset\.csv deletes only the first file.
  • The regex json/.* deletes all files in the json sub-directory.
  • The regex new deletes nothing.
  • The regex .*new.* deletes the file json/example_new.json (and all other files with new in the path)

We recommend testing your regular expression before using it. regex101.com is a nice service to test your regular expressions. This deep-link provides a test bed using the example files and the last expression from the list.
