Install:
https://pypi.python.org/pypi/ez
pip install ez
no dependencies
Almost all commands support the usage of '~', '..', '.', '?', '*' in path (ls,fls only support regular expression).
Symbolic link itself is the target of file operations; the actual file should be safe.
see also pyg.py
debug(1/0)
# 0 = everything will be actually executed
# 1 = simulate operations of cp, mv, execute; other commands will be actually performed.
will print out simulated commands, useful for debugging and for counting files when necessary.

To avoid typing email password each time, place a file named pygmailconfig.py with
EMAIL = 'someone@gmail.com'
PASSWORD = 'abcdefghik'
or better pygmailconfig.pyc
in the site-packages/ez folder, check with ez.which('ez')
The functions will no longer need email/password and become like this
Mail(to, subject, body, attach=None), AddEvent(event), Sheet(fileName)
Mail([EMAIL, PASSWORD, ] to, subject, body, attachment=None, bcc=None, cc=None, reply_to=None)
to/bcc/cc: ['a@a.com','b@b.com'] or 'a@a.com, b@b.com'
reply_to: 'a@a.com'
attachment: 'file_in_working_dir.txt' or ['a.txt','b.py','c.pdf']
AddEvent([EMAIL, PASSWORD, ] event) on DATE at TIME for DURATION in PLACE
Sheet([EMAIL, PASSWORD, ] fileName)
returns a sheet object representing "Sheet 1"
your google account doesn't have to the owner of this sheet, as long as you can edit it.
but you need to initialize/create this sheet and maybe the header by hand to begin with
the header could have spaces, ? etc, and when they are used as the keywords of dictionary, they are all converted to lowercase and all illegal characters are removed e.g. Delayed Test_date? --> delayedtestdate
fileName should be unique, can have spaces
GetRows(query=None, order_by=None,
reverse=None, filter_func=None)
:param query:
A string structured query on the full text in the worksheet.
[columnName][binaryOperator][value]
Supported binaryOperators are:
- (), for overriding order of operations
- = or ==, for strict equality
- <> or !=, for strict inequality
- and or &&, for boolean and
- or or ||, for boolean or.
:param order_by:
A string which specifies what column to use in ordering the
entries in the feed. By position (the default): 'position' returns
rows in the order in which they appear in the GUI. Row 1, then
row 2, then row 3, and so on. By column:
'column:columnName' sorts rows in ascending order based on the
values in the column with the given columnName, where
columnName is the value in the header row for that column.
:param reverse:
A string which specifies whether to sort in descending or ascending
order.Reverses default sort order: 'true' results in a descending
sort; 'false' (the default) results in an ascending sort.
:param filter_func:
A lambda function which applied to each row, Gets a row dict as
argument and returns True or False. Used for filtering rows in
memory (as opposed to query which filters on the service side).
:return:
A list of row dictionaries.
UpdateRow(row_data):
Update Row (By ID).
Only the fields supplied will be updated.
:param row_data:
A dictionary containing row data. The row will be updated according
to the value in the ID_FIELD.
:return:
The updated row.
UpdateRowByIndex(index, row_data):
Update Row By Index
:param index:
An integer designating the index of a row to update (zero based).
Index is relative to the returned result set, not to the original
spreadseet.
:param row_data:
A dictionary containing row data.
:return:
The updated row.
InsertRow(row_data):
Append Row at the end
:param row_data:
A dictionary containing row data.
:return:
A row dictionary for the inserted row.
DeleteRow(row):
Delete Row (By ID).
Requires that the given row dictionary contains an ID_FIELD.
:param row:
A row dictionary to delete.
DeleteRowByIndex(index):
Delete Row By Index
:param index:
A row index. Index is relative to the returned result set, not to
the original spreadsheet.
DeleteAllRows():
Delete All Rows
Raw data
