Sure it is. Here is a sample promise (take into consideration that I'm not
looking into any real php.ini while writing this):
bundle agent php
{
files:
"/usr/local/etc/php.ini"
edit_line => mem_limit("35"),
comment => "Enforce memory limit";
}
bundle edit_line mem_limit(x)
{
classes:
"enforce" not => regline("mem_limit\s*=\s*$(x)", "$(edit.filename)");
delete_lines:
enforce::
"mem_limit\s*=.*" comment => "Remove unmatched value if any";
insert_lines:
enforce::
"mem_limit = $(x)" comment => "Add requested value";
}
Please note I'm not using replace_with here because a line might be not present
there at all.
