|
|
|
|
- Update to version 5.5.0
|
|
* Positional indexing and other data-cleaning features
|
|
Features:
|
|
* The new positional-indexing feature resolves #236 from
|
|
@aborruso. You can now get the name of the 3rd field of each
|
|
record via $[[3]], and its value by $[[[3]]]. These are both
|
|
usable on either the left-hand or right-hand side of assignment
|
|
statements, so you can more easily do things like renaming
|
|
fields progrmatically within the DSL.
|
|
* There is a new capitalize DSL function, complementing the
|
|
already-existing toupper. This stems from #236.
|
|
* There is a new skip-trivial-records verb, resolving #197.
|
|
Similarly, there is a new remove-empty-columns verb, resolving
|
|
#206. Both are useful for data-cleaning use-cases.
|
|
* Another pair is #181 and #256. While Miller uses mmap
|
|
internally (and invisibily) to get approximately a 20%
|
|
performance boost over not using it, this can cause
|
|
out-of-memory issues with reading either large files, or too
|
|
many small ones. Now, Miller automatically avoids mmap in these
|
|
cases. You can still use --mmap or --no-mmap if you want manual
|
|
control of this.
|
|
* There is a new --ivar option for the nest verb which
|
|
complements the already-existing --evar. This is from #260
|
|
thanks to @jgreely.
|
|
* There is a new keystroke-saving urandrange DSL function:
|
|
urandrange(low, high) is the same as low + (high - low) *
|
|
urand().
|
|
* There is a new -v option for the cat verb which writes a
|
|
low-level record-structure dump to standard error.
|
|
* There is a new -N option for mlr which is a keystroke-saver
|
|
for --implicit-csv-header --headerless-csv-output.
|
|
Documentation:
|
|
* The new FAQ entry
|
|
http://johnkerl.org/miller/doc/faq.html#How_to_escape_'%3F'_in_re
|
|
gexes%3F resolves #203.
|
|
* The new FAQ entry
|
|
http://johnkerl.org/miller/doc/faq.html#How_can_I_filter_by_date%
|
|
3F resolves #208.
|
|
* #244 fixes a documentation issue while highlighting the need
|
|
for #241.
|
|
Bugfixes:
|
|
* There was a SEGV using nest within then-chains, fixed in
|
|
response to #220.
|
|
* Quotes and backslashes weren't being escaped in JSON output
|
|
with --jvquoteall; reported on #222.

|
|
|
|
- Update to version 5.4.0
|
|
Features:
|
|
* The new clean-whitespace verb resolves #190 from @aborruso.
|
|
Along with the new functions strip, lstrip, rstrip,
|
|
collapse_whitespace, and clean_whitespace, there is now both
|
|
coarse-grained and fine-grained control over whitespace
|
|
within field names and/or values. See the linked-to
|
|
documentation for examples.
|
|
* The new altkv verb resolves #184 which was originally opened
|
|
via an email request. This supports mapping value-lists such
|
|
as a,b,c,d to alternating key-value pairs such as a=b,c=d.
|
|
* The new fill-down verb resolves #189 by @aborruso. See the
|
|
linked-to documentation for examples.
|
|
* The uniq verb now has a uniq -a which resolves #168 from
|
|
@sjackman.
|
|
* The new regextract and regextract_or_else functions resolve
|
|
#183 by @aborruso.
|
|
* The new ssub function arises from #171 by @dohse, as a
|
|
simplified way to avoid escaping characters which are special
|
|
to regular-expression parsers.
|
|
* There are new localtime functions in response to #170 by
|
|
@sitaramc. However note that as discussed on #170 these do
|
|
not undo one another in all circumstances. This is a
|
|
non-issue for timezones which do not do DST. Otherwise, please
|
|
use with disclaimers: localdate, localtime2sec, sec2localdate,
|
|
sec2localtime, strftime_local, and strptime_local.
|
|
* Travis builds at
|
|
https://travis-ci.org/johnkerl/miller/builds now run on OSX as
|
|
well as Linux.
|
|
* An Ubuntu 17 build issue was fixed by @singalen on #164.
|
|
Documentation:
|
|
* put/filter documentation was confusing as reported by
|
|
@NikosAlexandris on #169.
|
|
* The new FAQ entry
|
|
http://johnkerl.org/miller-releases/miller-head/doc/faq.html#How_
|
|
to_rectangularize_after_joins_with_unpaired? resolves #193 by
|
|
@aborruso.
|
|
* The new cookbook entry
|
|
http://johnkerl.org/miller/doc/cookbook.html#Options_for_dealing_
|
|
with_duplicate_rows arises from #168 from @sjackman.
|
|
* The unsparsify documentation had some words missing as
|
|
reported by @tst2005 on #194.
|
|
* There was a typo in the cookpage page
|
|
http://johnkerl.org/miller/doc/cookbook.html#Full_field_renames_a
|
|
nd_reassigns as fixed by @tst2005 in #192.
|
|
Bugfixes:
|
|
* There was a memory leak for TSV-format files only as
|
|
reported by @treynr on #181.
|
|
* Dollar sign in regular expressions were not being escaped
|
|
properly as reported by @dohse on #171.

|
|
|
|
- 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.

|
|

|
|
reading from standard input (e.g. on a pipe or less-than
|
|
redirect).
