# To answer your question:
# Yes! This will indeed print matches for any occurence of `apply_filters` or `do_action`
# within .php files, including substring matches,
# and any occurrences that may be within doc blocks.
#
# Why?
# Mostly because I really don't want to write that awk regex.
# In addition, adding this would potentially introduce some weird bugs,
# due to the varying ways in which inline comments are added/decorated.

__log="hooks.log"

# The dir to scan. Set it to the relative dir you need to scan.

# For example, if you were using AffiliateWP, and this script is located in the site root:
__setdir="wp-content/plugins/affiliate-wp/includes/"
# __setdir="your/cool/plugin"

# time
__now=$(date +"%Y-%m-%d at %T")
