893 | 2009-11-20 | cif/ Generating _diffrn_ambient_temperature and _diffrn_ambient_pressure tags from the CIF file comments like "T = 100K" (using the 975 revision of cif_create_AMCSD_pressure_temp_tags). Mostly, series 9 CIFs (obtained AMCSD) have such comments. Only files that did not had these tags originally were changed. The tags were generated using the following command: ( \ set -x; \ find $(/bin/ls -rd ?) -name \*.cif \ | xargs -n1 -iX \ bash -c 'awk "/^#/,/^data_/{print}/^data_/{exit}" X \ | grep -v "^data_" > tmp-$$; \ cif_create_AMCSD_pressure_temp_tags X >> tmp-$$; \ if (grep -q _diffrn_ambient_temperature tmp-$$ >& /dev/null && \ ! grep -q _diffrn_ambient_temperature X >& /dev/null) || \ (grep -q _diffrn_ambient_pressure tmp-$$ >& /dev/null && \ ! grep -q _diffrn_ambient_pressure X >& /dev/null); \ then \ mv -v tmp-$$ X; \ fi; \ rm -f tmp-$$' \ ) >& make-temp-pressure-tags.log After this, the modified files were checked using 'vcif': svn st | grep ^M | awk '{print $NF}' | xargs -n1 vcif -l 2048 It was checked that for the other tags, only tag order and value formatting has changed in the modifed files, if at all: ( \ set -x; \ svn st ? \ | awk '/^M/{print $NF}' \ | sort \ | xargs -n1 -iX \ bash -c 'echo -e "\n"=== X ===; \ diff -b \ <(svn cat X | sort) \ <(sort X)' \ ) 2>&1 | tee diff-sorted.log tdbgrep === diff-sorted.log \ | grep -v ^=== \ | grep -v '^> _diffrn_' \ | grep . \ | grep -vE '^[0-9]+a[0-9]+' \ | less and the changed files were validated against the cif_core.dic (thus checking, among others checks, that the values of the inserted tags have correct types): ( \ set -x; \ svn st ? \ | awk '/^M/{print $NF}' \ | sort \ | xargs -n1 -iX \ bash -c 'echo === X ===; \ cif_validate \ --dic ~/struct/CIF-dictionaries/cif_core.dic \ X \ --check-all \ --do-not-check-tag-exists-local' \ ) >& validate-pressure-temperature.log |

846 | 2009-11-14 | cif/ Fixing _journal_volume values that had series letters prepended to them. Now the series letters are appended to the _journal_name_full, if needed, and the _journal_volume is purely numeric. To mimimise textual changes to CIFs this was done in several stages. First of all, a list of _journal_volume was compiled from the COD CIF collection: bash -xc 'find ? -name \*.cif \ | xargs cif_values \ --file \ --tag _journal_volume' \ >& cod-journal-volumes-`-date`.log & giving us a cod-journal-volumes-2009.11.13.log file (committed for reference as well). Then a list of volume names with letters was extracted and most of them transformed automatically into a correct form: awk '$3~/^[A-Z][0-9]/' cod-journal-volumes-2009.11.13.log \ | awk '{print $1}' \ | xargs -n1 -iI \ bash -c 'echo === I ===;\ awk "/^#/,/^data_/{print}/^data_/{exit}" I > tmp-$$; \ cif_adjust_journal_name_volume I \ | grep -E "_journal_name_full|_journal_volume" >> tmp-$$; \ awk "/^data_/,/\$eof/" I \ | grep -vE "^(data_|_journal_name_full|_journal_volume)" >> tmp-$$;\ mv -v tmp-$$ I' Note that this procedure assumes that all tags are at the beginning of the line, each value follows its tag on the same line, and there is only one tag per line. This procedure is not suitable for general CIFs, but fortunately, only very few CIFs in COD do not conform these rules. After the automatic conversion, a syntax check was run: svn st ? \ | awk '{print $NF}' \ | xargs -n1 -iI sh -c 'echo -n I"\r"; vcif -l 2048 I || echo "!!! I !!!\n"' Entries that were found to have errors (very few, less than 10) were reverted and fixed manually. The entries that had letters embedded into them were grepped separately: awk '$3~/[A-Z][0-9]/' cod-journal-volumes-2009.11.13.log \ | awk '$3~/^[^A-Z]/' and fixed manually. After all fixes, the previous 'vcif' test was rerun, yielding no syntax errors, and in addition a 'cif_filter' roundtrip test was run: svn st ? \ | awk '{print $NF}' \ | xargs -n1 -iI \ bash -c ' \ echo -en I "\r"; \ diff \ <(cif_filter I >& /dev/null) \ <(cif_filter I | cif_filter >& /dev/null) \ || echo "!!! I !!!\n"' This last test discovered one misspelled '_journal_yrae' tag in the 2/2003193.cif entry that was fixed by hand. |
