--------------------------------------------
Summary: [freemarker-generator] Support custom pattern definitions
for Grok tool
Key: FREEMARKER-181
URL: https://issues.apache.org/jira/browse/FREEMARKER-181
Project: Apache Freemarker
Issue Type: Bug
Reporter: Siegfried Goeschl
Need to parse through a bunch of server log files to extract response times but
I want to define the required pattern definitions directly in the FTL instead
of changing "/patterns/patterns".
So something like this should work
{code:java}
<#assign patternDefinitions = {
"MY_DATE": "%{YEAR}-%{MONTHNUM}-%{MONTHDAY}",
"MY_TIMESTAMP": "%{MY_DATE:date} %{TIME:time},%{INT:millis}",
"MY_MODULE": "\\[%{NOTSPACE}\\]",
"MY_THREAD": "\\(%{NOTSPACE}\\)",
"MY_SERVERLOG": "%{MY_TIMESTAMP} %{LOGLEVEL}%{SPACE:UNWANTED}%{MY_MODULE}
%{MY_THREAD} message response handled in: %{INT:response_time} ms;
%{GREEDYDATA:UNWANTED}"
}>
<#assign grok = tools.grok.compile("%{MY_SERVERLOG}", patternDefinitions)>
{code}
