mlr unspace verb

[johnkerl]

Since PPRINT format uses spaces as delimiters, PPRINT output is not invertible if data keys or values contain spaces. mlr unspace helps.

Before:

$ mlr --c2p cat data/spaces.csv
column 1 column 2 column 3
apple    ball     cat
dale egg fish     gale

$ mlr --icsv --opprint cat data/spaces.csv | mlr --ipprint --oxtab cat
mlr: mlr: CSV header/data length mismatch 6 != 3 at filename (stdin) line  2.
.

After:

$ mlr --c2p unspace data/spaces.csv
column_1 column_2 column_3
apple    ball     cat
dale_egg fish     gale

$ mlr --icsv --opprint unspace data/spaces.csv | mlr --ipprint --oxtab cat
column_1 apple
column_2 ball
column_3 cat

column_1 dale_egg
column_2 fish
column_3 gale

Nice! If there were also a verb to change the case of keys (e.g. lowercase, uppercase), fields could be normalized across different files without having to use the nuclear $ = {} option in a put expression 👍

[johnkerl]

nuclear $ = {}

LOL 😁
