I'm happy to announce that Spot 1.2.1 has been released.
These release improves the CSV reporting of ltlcross (including size
for Rabin or Streett automata, separate measurements in case multiple
products are used, and information about the exit status of the
translators). As a consequence the order of columns has changed
slightly, and it will break scripts that use hardcoded column
positions. If you want to get a CSV output that is closest to what
ltlcross used to output before, use the --omit-missing option (but
even with that the "time" column has been shifted left). Other tools
have also learned how to read CSV files, and have some options to help
creating CSV files.

New in spot 1.2.1 (2013-12-11)
* New features:
- commands for translators specified to ltlcross can now
be given "short names" to be used in the CSV or JSON output.
For instance
ltlcross '{small} ltl2tgba -s --small %f >%N' ...
will run the command "ltl2tgba -s --small %f >%N", but only
print "small" in output files.
- ltlcross' CSV and JSON output now contains two additional
columns: exit_status and exit_code, used to report failures of
the translator. If the translation failed, only the time is
reported, and the rest of the statistics, which are missing,
area left empty (in CVS) or null (in JSON). A new option,
--omit-missing can be used to remove lines for failed
translations, and remove these two columns.
- if ltlcross is used with --products=+5 instead of --products=5
then the stastics for each of the five products will be output
separately instead of being averaged.
- if ltlcross is used with tools that produce deterministic Streett
or Rabin automata (as specified with %D), then the statistics
output in CSV or JSON will have some extra columns to report
the size of these input automata before ltlcross converts them
into TGBA to perform its regular checks.
- ltlfilt, ltl2tgba, ltl2tgta, and ltlcross can now read formulas
from CSV files. Use option -F FILE/COL to read formulas from
column COL of FILE. Use -F FILE/-COL if the first line of
FILE be ignored.
- when ltlfilt processes formulas from a CSV file, it will output
each CSV line whose formula matches the given constraints, with
the rewriten formula. The new escape sequence %< (text in
columns before the formula) and %> (text after) can be used
with the --format option to alter this output.
- ltlfile, genltl, randltl, and ltl2tgba have a --csv-escape option
to help escape formulas in CSV files.
- Please check
http://spot.lip6.fr/userdoc/csv.html
for some discussion and examples of the last few features.
* Bug fixes:
- ltlcross' CSV output has been changed to be more RFC 4180
compliant: it no longuer output useless cosmetic spaces, and
use double-quotes with proper escaping for strings. The only
RFC 4180 rule that it does not follow is that it will terminate
lines with \n instead of \r\n because the latter cause issues
with a couple of tools.
- ltlcross failed to report missing input or output escape sequences
on all but the first configured translator.
