Version: 6.2.0-1
Severity: normal
Hi Stephen,
Thank you very much for maintaining Debian's
miller package.
I'm so impressed with how
practical and
sophisticated
it is that I'm inclined to describe it as "an
intellectual tour de force".
The main reason I'm writing is to report what I
think may be
a minor parsing error and
a way to work around it.
Here's a nice, short and sweet one liner that
demonstrates the problem on bash's command line,
at least on my computer:
$ echo | mlr put -q 'print 2**-0.5'
mlr: cannot parse DSL expression.
Parse error on token "-" at line 1 column 10.
Expected one of:
{ ( field_name $[ braced_field_name $[[ $[[[ full_srec oosvar_name @[
braced_oosvar_name
full_oosvar all non_sigil_name float int string_literal
regex_case_insensitive
int_literal float_literal boolean_literal null_literal inf_literal
nan_literal
const_M_PI const_M_E panic [ ctx_IPS ctx_IFS ctx_IRS ctx_OPS ctx_OFS
ctx_ORS
ctx_FLATSEP ctx_NF ctx_NR ctx_FNR ctx_FILENAME ctx_FILENUM env func
Please note that mlr appears to be unable to parse
the negative exponent "-0.5".
I'm happy to report I worked around the problem by
enclosing the negative exponent in parentheses.
Here's an example:
$ echo | mlr put -q 'print 2**(-0.5)'
0.7071067811865475
If you decide to mention this issue to the
upstream author, John Kerl, feel free to let him
know how impressed I am with his code.
Thanks,
Kingsley
