------------------------------------------------------------------- Tue Jun 20 06:34:53 UTC 2017 - aloisio@gmx.com - Update to version 5.2.1 * Fixes (gh#johnkerl/miller#142) build segfault on non-x86 architectures ------------------------------------------------------------------- Tue Jun 13 08:06:28 UTC 2017 - aloisio@gmx.com - Update to version 5.2.0 This release contains mostly feature requests. Features: * The stats1 verb now lets you use regular expressions to specify which field names to compute statistics on, and/or which to group by. Full details are here. * The min and max DSL functions, and the min/max/percentile aggregators for the stats1 and merge-fields verbs, now support numeric as well as string field values. (For mixed string/numeric fields, numbers compare before strings.) This means in particular that order statistics -- min, max, and non-interpolated percentiles -- as well as mode, antimode, and count are now possible on string-only fields. (Of course, any operations requiring arithmetic on values, such as computing sums, averages, or interpolated percentiles, yield an error on string-valued input.) * There is a new DSL function mapexcept which returns a copy of the argument with specified key(s), if any, unset. The motivating use-case is to split records to multiple filenames depending on particular field value, which is omitted from the output: mlr --from f.dat put 'tee > "/tmp/data-".$a, mapexcept($*, "a")' Likewise, mapselect returns a copy of the argument with only specified key(s), if any, set. This resolves #137. * A new -u option for count-distinct allows unlashed counts for multiple field names. For example, with -f a,b and without -u, count-distinct computes counts for distinct pairs of a and b field values. With -f a,b and with -u, it computes counts for distinct a field values and counts for distinct b field values separately. * If you build from source, you can now do ./configure without first doing autoreconf -fiv. This resolves #131. * The UTF-8 BOM sequence 0xef 0xbb 0xbf is now automatically ignored from the start of CSV files. (The same is already done for JSON files.) This resolves #138. * For put and filter with -S, program literals such as the 6 in $x = 6 were being parsed as strings. This is not sensible, since the -S option for put and filter is intended to suppress numeric conversion of record data, not program literals. To get string 6 one may use $x = "6". Documentation: * A new cookbook example shows how to compute differences between successive queries, e.g. to find out what changed in time-varying data when you run and rerun a SQL query. * Another new cookbook example shows how to compute interquartile ranges. * A third new cookbook example shows how to compute weighted means. Bugfixes: * CRLF line-endings were not being correctly autodetected when I/O formats were specified using --c2j et al. * Integer division by zero was causing a fatal runtime exception, rather than computing inf or nan as in the floating-point case. ------------------------------------------------------------------- Sat Apr 15 07:48:57 UTC 2017 - aloisio@gmx.com - Update to 5.1.0 (see changelog at https://github.com/johnkerl/miller/releases/tag/v5.1.0) ------------------------------------------------------------------- Sun Mar 12 21:04:27 UTC 2017 - aloisio@gmx.com - Update to version 5.0.1 Minor bugfixes: * As described in #132, mlr nest was incorrectly splitting fields with multi-character separators. * The XTAB-format reader, when using multi-character IPS, was incorrectly splitting key-value pairs, but only when reading from standard input (e.g. on a pipe or less-than redirect). ------------------------------------------------------------------- Tue Feb 28 10:28:05 UTC 2017 - aloisio@gmx.com - Initial package (v5.0.0)
