Howto Update Spreadsheets

This document describes how to update the Packages/Uncategorized/*.csv FOIA patch spreadsheets using the latest .xls files from the VA VistA FOIA site.

Branch

Create a branch, say upstream-spreadsheets, starting from the last commit that updated the .csv files from the FOIA site:

base=$(git rev-list master -n 1 --author='va.gov' -- 'Packages/Uncategorized/*.csv') &&
git checkout -b upstream-spreadsheets $base

It is important to base the update branch on a version that has no other modifications since the last update from the FOIA site. This way the branch represents only the upstream changes and can be merged with changes made in other branches instead of overwriting them.

Download

Download the .xls files from the FOIA web site for some ${year}:

wget --continue --input-file=- --user-agent='' \
 https://downloads.va.gov/files/FOIA/Software/DBA_VistA_FOIA_System_Files/Listing_of_Released_VistA_Patches_${year}.xls

Convert

Obtain the xlsx2csv tool and hack it to recognize the VA dates:

git clone https://github.com/dilshod/xlsx2csv.git &&
(cd xlsx2csv && git reset --hard fa44ba6f &&
 sed -i '/  '"'"'d-mmm-yyyy'"'"'/ {p;i\
 '"'"'[$-409]d-mmm-yyyy;@'"'"' : '"'"'date'"'"',
 d}' xlsx2csv.py)

Run xlsx2csv to convert the .xls files to .csv format:

mkdir -p Packages/Uncategorized &&
for xls in *.xls; do
  csv="Packages/Uncategorized/${xls/xls/csv}" &&
  python xlsx2csv/xlsx2csv.py --ignoreempty --dateformat='%Y-%m-%d' "${xls}" "${csv}" &&
  fromdos "${csv}"
done &&
rm *.xls &&
rm -rf xlsx2csv

Remove extra rows from end of files by hand if desired.

If xlsx2csv complains about the format, use MS Excel to convert the .xls files to .xlsx and adjust the above command accordingly.

Commit

Add the changes and commit them with the VA as author:

git add Packages/Uncategorized/*.csv
git commit --author='US DVA <va.gov>'

Mention in the commit message this instructions file and the URL of the .xls file downloaded.

Merge

Create a branch, say update-spreadsheets, and merge the upstream changes:

git checkout -b update-spreadsheets master
git merge upstream-spreadsheets

If there are conflicts resolve them and commit with a message describing how.

Finally, push this topic for review like any other change.
