ASF GitHub Bot commented on METRON-1117: ---------------------------------------- GitHub user nickwallen opened a pull request: https://github.com/apache/metron/pull/704 METRON-1117 Filters Functions Returns by '%functions' As we continue to develop more Stellar functions, the list of functions returned by `%functions` in the REPL becomes hard to grok manually. I wanted a way to filter that list to narrow my search. What is that subnet function that we have? ``` [Stellar]>>> %functions NET IN_SUBNET ``` If no argument is provided, then all functions will be returned just like before. The filtering mechanism checks that the argument is a substring of the function name; meaning it uses `String.contains` under the hood. It does not use a regular expression. I debated with myself about which way to go and I decided that it would be easier to go this way; `%function NET` is easier than `%functions .*NET.*` ## Testing To test the change launch the REPL. ``` mvn clean install -DskipTests mvn exec:java -Dexec.mainClass="org.apache.metron.stellar.common.shell.StellarShell" -pl metron-platform/metron-enrichment ``` Then try-out the change to %functions. ``` [Stellar]>>> %functions ABS, APPEND_IF_MISSING, BIN, BLOOM_ADD, BLOOM_EXISTS, BLOOM_INIT, BLOOM_MERGE, CEILING, CHOMP, CHOP, COS, COUNT_MATCHES, DAY_OF_MONTH, DAY_OF_WEEK, DAY_OF_YEAR, DECODE, DOMAIN_REMOVE_SUBDOMAINS, DOMAIN_REMOVE_TLD, DOMAIN_TO_TLD, ENCODE, ENDS_WITH, ENRICHMENT_EXISTS, ENRICHMENT_GET, EXP, FILL_LEFT, FILL_RIGHT, FILTER, FLOOR, FORMAT, GEO_GET, GET, GET_FIRST, GET_LAST, GET_SUPPORTED_ENCODINGS, HLLP_ADD, HLLP_CARDINALITY, HLLP_INIT, HLLP_MERGE, IN_SUBNET, IS_DATE, IS_DOMAIN, IS_EMAIL, IS_EMPTY, IS_ENCODING, IS_INTEGER, IS_IP, IS_URL, JOIN, LENGTH, LIST_ADD, LN, LOG10, LOG2, MAP, MAP_EXISTS, MAP_GET, MONTH, OUTLIER_MAD_ADD, OUTLIER_MAD_SCORE, OUTLIER_MAD_STATE_MERGE, PREPEND_IF_MISSING, PROFILER_APPLY, PROFILER_FLUSH, PROFILER_INIT, PROFILE_FIXED, PROFILE_GET, PROFILE_WINDOW, PROTOCOL_TO_NAME, REDUCE, REGEXP_GROUP_VAL, REGEXP_MATCH, ROUND, SIN, SPLIT, SQRT, STARTS_WITH, STATS_ADD, STATS_BIN, STATS_COUNT, STATS_GEOMETRIC_MEAN, STATS_INIT, STATS_KURTOSIS, STATS_MAX, STATS_MEAN, STATS_MERGE, STATS_MIN, STATS_PERCENTILE, STATS_POPULATION_VARIANCE, STATS_QUADRATIC_MEAN, STATS_SD, STATS_SKEWNESS, STATS_SUM, STATS_SUM_LOGS, STATS_SUM_SQUARES, STATS_VARIANCE, STRING_ENTROPY, SYSTEM_ENV_GET, SYSTEM_PROPERTY_GET, TAN, TO_DOUBLE, TO_EPOCH_TIMESTAMP, TO_FLOAT, TO_INTEGER, TO_LONG, TO_LOWER, TO_STRING, TO_UPPER, TRIM, URL_TO_HOST, URL_TO_PATH, URL_TO_PORT, URL_TO_PROTOCOL, WEEK_OF_MONTH, WEEK_OF_YEAR, YEAR, ZIP, ZIP_LONGEST [Stellar]>>> %functions TO DOMAIN_TO_TLD, PROTOCOL_TO_NAME, STATS_KURTOSIS, TO_DOUBLE, TO_EPOCH_TIMESTAMP, TO_FLOAT, TO_INTEGER, TO_LONG, TO_LOWER, TO_STRING, TO_UPPER, URL_TO_HOST, URL_TO_PATH, URL_TO_PORT, URL_TO_PROTOCOL [Stellar]>>> %functions NET IN_SUBNET ``` ## Pull Request Checklist - [ ] Is there a JIRA ticket associated with this PR?
