changes.log tools

»changelog: usage: changelog logfile [file]

<sbp> what's the [file] argument in "changelog logfile [file]"?
<dpk> it will only show changes to that particular file

$ changelog changes.log | tail -n 1
163: by sbp to octavo-notes.html on Thu Feb 14 21:44:23 2013

»changeview: usage: changeview logfile revid

$ changeview changes.log 163 | head -n 1
octavo-notes.html as modified by sbp, Thu Feb 14 21:44:23 2013:
<!doctype html>

The first line there, "as modified", is printed to stderr.

»reindex: usage: reindex logfile

»validate: usage: validate logfile

Issues: validate actually does not emit any usage information. Both reindex and validate are broken with the same error message:

$ validate changes.log 
Traceback (most recent call last):
  File "validate", line 5, in <module>
    log = changes.changelog(sys.argv[1])
  File "changes.py", line 21, in __init__
    self.reindex()
  File "changes.py", line 42, in reindex
    tempfile = [...]+(".%d.temp" % datetime.datetime.now().timestamp())
AttributeError: 'datetime.datetime' object has no attribute 'timestamp'

This was discovered to be due to requiring python 3.3.

Recent changes

tail -c 1048576 changes.log | grep '<<<' | tail -n 72 | tac

Additions to emit nicely formed HTML are trivial, though group by date requires:

WHEN=$(date -d "@$TIMESTAMP")

if [[ "${WHEN%% *}" != "${OLD_WHEN%% *}" ]]
then echo "</ul><h2>${WHEN%% *}</h2><ul>"
fi
