Subject: input/csv: trim cell content before conversion
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=cd11e33c5de58edb0340fd9f25115aa4509f4767

input/csv: trim cell content before conversion

Trailing whitespace in CSV cells broke the text to number conversion.
Trim the text content of cells before processing it. This is useful and
actually essential for data cells, and does not harm titles in header
lines, neither will it affect column format specs.

How to reproduce:

  $ echo ' 3.14 , 2' | \
    sigrok-cli -i - -I csv:header=false:column_formats=2a
  sr: input/csv: Cannot parse analog text  3.14  in column 1 in line 1.
