available under the License, as indicated by a copyright notice that is included

||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object form, that
|
||||
is based on (or derived from) the Work and for which the editorial revisions,
|
||||
annotations, elaborations, or other modifications represent, as a whole, an

original work of authorship. For the purposes of this License, Derivative Works

||||
this License; and

|
||||
of the Work, excluding those notices that do not pertain to any part of the
|
||||
Derivative Works; and
|
||||
If the Work includes a "NOTICE" text file as part of its distribution, then any
|
||||
Derivative Works that You distribute must include a readable copy of the
|
||||
attribution notices contained within such NOTICE file, excluding those notices

|
||||
Derivative Works; within the Source form or documentation, if provided along
|
||||
with the Derivative Works; or, within a display generated by the Derivative
|
||||
Works, if and wherever such third-party notices normally appear. The contents of

the NOTICE file are for informational purposes only and do not modify the
|
||||
License. You may add Your own attribution notices within Derivative Works that
|
||||
You distribute, alongside or as an addendum to the NOTICE text from the Work,
|
||||
provided that such additional attribution notices cannot be construed as
|
||||
modifying the License.
|
||||

|
||||
additional or different license terms and conditions for use, reproduction, or
|
||||
distribution of Your modifications, or for any such Derivative Works as a whole,
|
||||
provided Your use, reproduction, and distribution of the Work otherwise complies
|
||||
with the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions.
|
||||
|
||||
Unless You explicitly state otherwise, any Contribution intentionally submitted
|
||||
for inclusion in the Work by You to the Licensor shall be under the terms and
|
||||
conditions of this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify the terms of
|
||||
any separate license agreement you may have executed with Licensor regarding
|
||||
such Contributions.
|
||||
|
||||
6. Trademarks.
|
||||
|
||||
This License does not grant permission to use the trade names, trademarks,
|
||||
service marks, or product names of the Licensor, except as required for
|
||||
reasonable and customary use in describing the origin of the Work and
|
||||
reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty.
|
||||
|
||||
Unless required by applicable law or agreed to in writing, Licensor provides the

|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
|
||||
including, without limitation, any warranties or conditions of TITLE,

NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are

|
||||
permissions under this License.
|

|
||||
8. Limitation of Liability.
|
||||
|
||||
In no event and under no legal theory, whether in tort (including negligence),
|
||||
contract, or otherwise, unless required by applicable law (such as deliberate
|
||||
and grossly negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special, incidental,
|
||||
or consequential damages of any character arising as a result of this License or
|
||||
out of the use or inability to use the Work (including but not limited to
|
||||
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
|
||||
any and all other commercial damages or losses), even if such Contributor has
|
||||
been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability.
|
||||
|
||||
While redistributing the Work or Derivative Works thereof, You may choose to
|
||||
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
|
||||
other liability obligations and/or rights consistent with this License. However,
|
||||
in accepting such obligations, You may act only on Your own behalf and on Your
|
||||
sole responsibility, not on behalf of any other Contributor, and only if You
|
||||
agree to indemnify, defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason of your
|
||||
accepting any such warranty or additional liability.

glog
|
||||
====
|
||||
|
||||
Leveled execution logs for Go.
|
||||
|
||||
This is an efficient pure Go implementation of leveled logs in the
|
||||
manner of the open source C++ package
|
||||
http://code.google.com/p/google-glog
|
||||
|
||||
By binding methods to booleans it is possible to use the log package
|
||||
without paying the expense of evaluating the arguments to the log.
|
||||
Through the -vmodule flag, the package also provides fine-grained
|
||||
control over logging at the file level.
|
||||
|
||||
The comment from glog.go introduces the ideas:
|
||||
|
||||
Package glog implements logging analogous to the Google-internal
|
||||
C++ INFO/ERROR/V setup. It provides functions Info, Warning,
|
||||
Error, Fatal, plus formatting variants such as Infof. It
|
||||
also provides V-style logging controlled by the -v and
|
||||
-vmodule=file=2 flags.
|
||||
|
||||
Basic examples:
|
||||
|
||||
glog.Info("Prepare to repel boarders")
|
||||
|
||||
glog.Fatalf("Initialization failed: %s", err)
|
||||
|
||||
See the documentation for the V function for an explanation
|
||||
of these examples:
|
||||
|
||||
if glog.V(2) {
|
||||
glog.Info("Starting transaction...")
|
||||
}
|
||||
|
||||
glog.V(2).Infoln("Processed", nItems, "elements")
|
||||
|
||||
|
||||
The repository contains an open source version of the log package
|
||||
used inside Google. The master copy of the source lives inside
|
||||
Google, not here. The code in this repo is for export only and is not itself
|
||||
under development. Feature requests will be ignored.
