Previously, gitinspector always tried to merge authors with the same name
(independently of the email). This behavior tends to (for the most part)
help in projects missing a .mailmap file. Often; authors commit under the
same name, but with different emails on different computers (if they for
example have a work email on their office desktop).
Whenever different e-mail addresses are used by an author; gitinspector
will use the last email it finds and will generate a gravatar from that
email address. This behavior was chosen because authors mostly do not tend
to create a gravatar image for their old email accounts (but often have
one in their newer ones).
References to gravatar images are generated with HTML and XML outputs only
as these are the only formats where referencing gravatars makes sense
right now. The HTMLEmbedded format, for example, does not link to any
gravatars as that format prohibits the use of external links.
To accommodate the new images; the width of the generated HTML page has
been slightly increased. However, the HTML page should still fit on a
1280 display.
This is a better solution than simply relying on ValueError and also
helps us to maintain compatibility with all our other exceptions (it gives
us a msg attribute that we can access when catching the error).
Also localized the string for InvalidRegExpError.
This was fixed by storing the exception string manually inside each
exception class. The error message is now stored in exception.msg instead
of relying on __str__(). It seems the normal behavior (by printing exceptions
directly) is broken in Python 2. It *does* work in Python 3, but this is
because it always handles everything as unicode.
The support for optional boolean arguments is the same; but uses
getopt instead of optparse.
The whole adventure with optparse was a giant waste of time and just
forced us to monkey-patch optparse with some very ugly solutions in order
to make it do what we wanted; thus it was better to switch back to the
more low-level getopt module.
To accomplish this; a optval.gnu_getopt() function was added that is a
duplicate of the original getopt.gnu_getopt function but with support for
optional arguments.
A long option which accepts an optional argument is denoted with
arg:default_value in the long_options string.
In the end, this solution feels much better than the one with optparse.
If gitinspector was not executed standing in the root directory of the
git repository (or with a git root specified at the command line),
"git ls-tree" would not find all files properly.
In the process, the new strings were also translated to Swedish. To
properly handle localized string constants, a new function "N_()" was
added which can be supplied to xgettext when collecting strings.
The default behaviour is now not to localize the output, only the help
text and error messages (all the user interaction).
The way localized messages are fetched in the modules has been modified
as well; to allow for the ability to enable and disable the localization.
Just like in many GNU tools, it is now possible to pass an optional
boolean to some of the flags of gitinspector in the form;
--flag[=BOOL]
This gives us the ability to override options set via git-config.
For example; say we did the following:
git-config --global inspector.timeline true
We could then override this setting when running gitinspector by supplying:
./gitinspector.py --timeline=false
Implementing this was not a trivial task, as no command-line parser in
Python supports this by default (getopt, optparse, argparse). In order to
properly handle optional boolean arguments; some clever patching had to
be done to the command-line in combination with a callback function that
can handle boolean strings. To maintain compatibility with Python 2.6,
this was implemented using optparse (instead of argparse).
This function moves most of the logic of handling comments into the
comment module itself, thus avoiding duplicated code and allowing for
a cleaner solution.
In contrast to the -x/--exclude option that can be given on the command
line, --exclude can not be set multiple times when used with git-config.
Luckily, the same behavior can be attained by using the pipe ("|")
character. Ie, specifying the following on the command line:
-x "hello.txt" -x "goodbye.txt"
is the same thing as:
-x "hello.txt|goodbye.txt"
when sent to git-config or the command line.
