(defun timeclock-log-data (&optional recent-only filename)
"Return the contents of the timelog file, in a useful format.
A timelog contains data in the form of a single entry per line.
Each entry has the form:
CODE YYYY/MM/DD HH:MM:SS [COMMENT]
CODE is one of: b, h, i, o or O. COMMENT is optional when the code is
i, o or O. The meanings of the codes are:
b Set the current time balance, or \"time debt\". Useful when
archiving old log data, when a debt must be carried forward.
The COMMENT here is the number of seconds of debt.
h Set the required working time for the given day. This must
be the first entry for that day. The COMMENT in this case is
the number of hours that must be worked. Floating point
amounts are allowed.
i Clock in. The COMMENT in this case should be the name of the
project worked on.
o Clock out. COMMENT is unnecessary, but can be used to provide
a description of how the period went, for example.
O Final clock out. Whatever project was being worked on, it is
now finished. Useful for creating summary reports.
When this function is called, it will return a data structure with the
following format:
(DEBT ENTRIES-BY-DAY ENTRIES-BY-PROJECT)
DEBT is a floating point number representing the number of seconds
\"owed\" before any work was done. For a new file (one without a 'b'
entry), this is always zero.
The two entries lists have similar formats. They are both alists,
where the CAR is the index, and the CDR is a list of time entries.
For ENTRIES-BY-DAY, the CAR is a textual date string, of the form
YYYY/MM/DD. For ENTRIES-BY-PROJECT, it is the name of the project
worked on, or t for the default project.
The CDR for ENTRIES-BY-DAY is slightly different than for
ENTRIES-BY-PROJECT. It has the following form:
(DAY-LENGTH TIME-ENTRIES...)
For ENTRIES-BY-PROJECT, there is no DAY-LENGTH member. It is simply a
list of TIME-ENTRIES. Note that if DAY-LENGTH is nil, it means
whatever is the default should be used.
A TIME-ENTRY is a recorded time interval. It has the following format
\(although generally one does not have to manipulate these entries
directly; see below):
(BEGIN-TIME END-TIME PROJECT [COMMENT] [FINAL-P])
Anyway, suffice it to say there are a lot of structures. Typically
the user is expected to manipulate to the day(s) or project(s) that he
or she wants, at which point the following helper functions may be
used:
timeclock-day-required
timeclock-day-length
timeclock-day-debt
timeclock-day-begin
timeclock-day-end
timeclock-day-span
timeclock-day-break
timeclock-day-projects
timeclock-day-list-required
timeclock-day-list-length
timeclock-day-list-debt
timeclock-day-list-begin
timeclock-day-list-end
timeclock-day-list-span
timeclock-day-list-break
timeclock-day-list-projects
timeclock-entry-length
timeclock-entry-begin
timeclock-entry-end
timeclock-entry-project
timeclock-entry-comment
timeclock-entry-list-length
timeclock-entry-list-begin
timeclock-entry-list-end
timeclock-entry-list-span
timeclock-entry-list-break
timeclock-entry-list-projects
A few comments should make the use of the above functions obvious:
`required' is the amount of time that must be spent during a day, or
sequence of days, in order to have no debt.
`length' is the actual amount of time that was spent.
`debt' is the difference between required time and length. A
negative debt signifies overtime.
`begin' is the earliest moment at which work began.
`end' is the final moment work was done.
`span' is the difference between begin and end.
`break' is the difference between span and length.
`project' is the project that was worked on, and `projects' is a
list of all the projects that were worked on during a given period.
`comment', where it applies, could mean anything.
There are a few more functions available, for locating day and entry
lists:
timeclock-day-alist LOG-DATA
timeclock-project-alist LOG-DATA
timeclock-current-debt LOG-DATA
See the documentation for the given function if more info is needed."
