+[![Build Status](https://img.shields.io/travis/davecgh/go-spew.svg)](https://travis-ci.org/davecgh/go-spew)
+[![ISC License](http://img.shields.io/badge/license-ISC-blue.svg)](http://copyfree.org)
+[![Coverage Status](https://img.shields.io/coveralls/davecgh/go-spew.svg)](https://coveralls.io/r/davecgh/go-spew?branch=master)
+
+Go-spew implements a deep pretty printer for Go data structures to aid in
+debugging.  A comprehensive suite of tests with 100% test coverage is provided
+to ensure proper functionality.  See `test_coverage.txt` for the gocov coverage
+report.  Go-spew is licensed under the liberal ISC license, so it may be used in
+open source or commercial projects.
+
+If you're interested in reading about how this package came to life and some
+of the challenges involved in providing a deep pretty printer, there is a blog
+post about it
+[here](https://web.archive.org/web/20160304013555/https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).
+
+## Documentation
+
+[![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)](http://godoc.org/github.com/davecgh/go-spew/spew)
+
+Full `go doc` style documentation for the project can be viewed online without
+installing this package by using the excellent GoDoc site here:
+http://godoc.org/github.com/davecgh/go-spew/spew
+
+You can also view the documentation locally once the package is installed with
+the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
+http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
+
+## Installation
+
+```bash
+$ go get -u github.com/davecgh/go-spew/spew
+```
+
+## Quick Start
+
+Add this import line to the file you're working in:
+
+```Go
+import "github.com/davecgh/go-spew/spew"
+```
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+
+```Go
+spew.Dump(myVar1, myVar2, ...)
+spew.Fdump(someWriter, myVar1, myVar2, ...)
+str := spew.Sdump(myVar1, myVar2, ...)
+```
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
+compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
+and pointer addresses): 
+
+```Go
+spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+```
+
+## Debugging a Web Application Example
+
+Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
+
+```Go
+package main
+
+import (
+    "fmt"
+    "html"
+    "net/http"
+
+    "github.com/davecgh/go-spew/spew"
+)
+
+func handler(w http.ResponseWriter, r *http.Request) {
+    w.Header().Set("Content-Type", "text/html")
+    fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
+    fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
+}
+
+func main() {
+    http.HandleFunc("/", handler)
+    http.ListenAndServe(":8080", nil)
+}
+```
+
+## Sample Dump Output
+
+```
+(main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+  flag: (main.Flag) flagTwo,
+  data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) {
+  (string) "one": (bool) true
+ }
+}
+([]uint8) {
+ 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+ 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+ 00000020  31 32                                             |12|
+}
+```
+
+## Sample Formatter Output
+
+Double pointer to a uint8:
+```
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+```
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+```
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+```
+
+## Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available via the
+spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the ConfigState documentation for more details.
+
+```
+* Indent
+	String to use for each indentation level for Dump functions.
+	It is a single space by default.  A popular alternative is "\t".
+
+* MaxDepth
+	Maximum number of levels to descend into nested data structures.
+	There is no limit by default.
+
+* DisableMethods
+	Disables invocation of error and Stringer interface methods.
+	Method invocation is enabled by default.
+
+* DisablePointerMethods
+	Disables invocation of error and Stringer interface methods on types
+	which only accept pointer receivers from non-pointer variables.  This option
+	relies on access to the unsafe package, so it will not have any effect when
+	running in environments without access to the unsafe package such as Google
+	App Engine or with the "safe" build tag specified.
+	Pointer method invocation is enabled by default.
+
+* DisablePointerAddresses
+	DisablePointerAddresses specifies whether to disable the printing of
+	pointer addresses. This is useful when diffing data structures in tests.
+
+* DisableCapacities
+	DisableCapacities specifies whether to disable the printing of capacities
+	for arrays, slices, maps and channels. This is useful when diffing data
+	structures in tests.
+
+* ContinueOnMethod
+	Enables recursion into types after invoking error and Stringer interface
+	methods. Recursion after method invocation is disabled by default.
+
+* SortKeys
+	Specifies map keys should be sorted before being printed. Use
+	this to have a more deterministic, diffable output.  Note that
+	only native types (bool, int, uint, floats, uintptr and string)
+	and types which implement error or Stringer interfaces are supported,
+	with other types sorted according to the reflect.Value.String() output
+	which guarantees display stability.  Natural map order is used by
+	default.
+
+* SpewKeys
+	SpewKeys specifies that, as a last resort attempt, map keys should be
+	spewed to strings and sorted by those strings.  This is only considered
+	if SortKeys is true.
+
+```
+
+## Unsafe Package Dependency
+
+This package relies on the unsafe package to perform some of the more advanced
+features, however it also supports a "limited" mode which allows it to work in
+environments where the unsafe package is not available.  By default, it will
+operate in this mode on Google App Engine and when compiled with GopherJS.  The
+"safe" build tag may also be specified to force the package to build without
+using the unsafe package.

+
+## install
+
+`go get github/go-pkgz/lgr`
+
+## usage
+
+```go
+    l := lgr.New(lgr.Debug, lgr.Caller) // allow debug and caller info
+    l.Logf("INFO some important err message, %v", err)
+    l.Logf("DEBUG some less important err message, %v", err)
+```
+
+output looks like this:
+```
+2018/01/07 13:02:34.000 INFO  {svc/handler.go:101 h.MyFunc1} some important err message, can't open file`
+2018/01/07 13:02:34.015 DEBUG {svc/handler.go:155 h.MyFunc2} some less important err message, file is too small`
+```
+
+_Without `lgr.Caller` it will drop `{caller}` part_
+
+## details
+
+### interfaces and default loggers
+
+- `lgr` package provides a single interface `lgr.L` with a single method `Logf(format string, args ...interface{})`. Function wrapper `lgr.Func` allows to make `lgr.L` from a function directly.
+- Default logger functionality can be used without `lgr.New`, but just `lgr.Printf`
+- Two predefined loggers available: `lgr.NoOp` (do-nothing logger) and `lgr.Std` (passing directly to stdlib log)
+
+### options
+
+`lgr.New` call accepts functional options:
+
+- `lgr.Debug` - turn debug mode on. This allows messages with "DEBUG" level (filtered overwise)
+- `lgr.Caller` - adds the caller info each message
+- `lgr.Out(io.Writer)` - sets the output writer, default `os.Stdout`
+- `lgr.Err(io.Writer)` - sets the error writer, default `os.Stderr`
+
+### levels
+
+`lgr.Logf` recognizes prefixes like "INFO" or "[INFO]" as levels. The full list of supported levels - "DEBUG", "INFO", "WARN", "ERROR", "PANIC" and "FATAL"
+
+- `DEBUG` will be filtered unless `lgr.Debug` option defined
+- `INFO` and `WARN` don't have any special behavior attached
+- `ERROR` sends messages to both out and err writers
+- "PANIC" and "FATAL" send messages to both out and err writers. In addition sends dump of callers and runtime info to err only, and call `os.Exit(1)`.

-        or its Contributor Version.
-
-2.2. Effective Date
-
-     The licenses granted in Section 2.1 with respect to any Contribution become
-     effective for each Contribution on the date the Contributor first distributes
-     such Contribution.
-
-2.3. Limitations on Grant Scope
-
-     The licenses granted in this Section 2 are the only rights granted under this
-     License. No additional rights or licenses will be implied from the distribution
-     or licensing of Covered Software under this License. Notwithstanding Section
-     2.1(b) above, no patent license is granted by a Contributor:
-
-     a. for any code that a Contributor has removed from Covered Software; or
-
-     b. for infringements caused by: (i) Your and any other third party’s
-        modifications of Covered Software, or (ii) the combination of its
-        Contributions with other software (except as part of its Contributor
-        Version); or
-
-     c. under Patent Claims infringed by Covered Software in the absence of its
-        Contributions.
-
-     This License does not grant any rights in the trademarks, service marks, or
-     logos of any Contributor (except as may be necessary to comply with the
-     notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-     No Contributor makes additional grants as a result of Your choice to
-     distribute the Covered Software under a subsequent version of this License
-     (see Section 10.2) or under the terms of a Secondary License (if permitted
-     under the terms of Section 3.3).
-
-2.5. Representation
-
-     Each Contributor represents that the Contributor believes its Contributions
-     are its original creation(s) or it has sufficient rights to grant the
-     rights to its Contributions conveyed by this License.
-
-2.6. Fair Use
-
-     This License is not intended to limit any rights You have under applicable
-     copyright doctrines of fair use, fair dealing, or other equivalents.
-
-2.7. Conditions
-
-     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
-     Section 2.1.
-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under the
-     terms of this License. You must inform recipients that the Source Code Form
-     of the Covered Software is governed by the terms of this License, and how
-     they can obtain a copy of this License. You may not attempt to alter or
-     restrict the recipients’ rights in the Source Code Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this License,
-        or sublicense it under different terms, provided that the license for
-        the Executable Form does not attempt to limit or alter the recipients’
-        rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for the
-     Covered Software. If the Larger Work is a combination of Covered Software
-     with a work governed by one or more Secondary Licenses, and the Covered
-     Software is not Incompatible With Secondary Licenses, this License permits
-     You to additionally distribute such Covered Software under the terms of
-     such Secondary License(s), so that the recipient of the Larger Work may, at
-     their option, further distribute the Covered Software under the terms of
-     either this License or such Secondary License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices (including
-     copyright notices, patent notices, disclaimers of warranty, or limitations
-     of liability) contained within the Source Code Form of the Covered
-     Software, except that You may alter any license notices to the extent
-     required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on behalf
-     of any Contributor. You must make it absolutely clear that any such
-     warranty, support, indemnity, or liability obligation is offered by You
-     alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute, judicial
-   order, or regulation then You must: (a) comply with the terms of this License
-   to the maximum extent possible; and (b) describe the limitations and the code
-   they affect. Such description must be placed in a text file included with all
-   distributions of the Covered Software under this License. Except to the
-   extent prohibited by statute or regulation, such description must be
-   sufficiently detailed for a recipient of ordinary skill to be able to
-   understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
-     if such Contributor fails to notify You of the non-compliance by some
-     reasonable means prior to 60 days after You have come back into compliance.
-     Moreover, Your grants from a particular Contributor are reinstated on an
-     ongoing basis if such Contributor notifies You of the non-compliance by
-     some reasonable means, this is the first time You have received notice of
-     non-compliance with this License from such Contributor, and You become
-     compliant prior to 30 days after Your receipt of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions, counter-claims,
-     and cross-claims) alleging that a Contributor Version directly or
-     indirectly infringes any patent, then the rights granted to You by any and
-     all Contributors for the Covered Software under Section 2.1 of this License
-     shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an “as is” basis, without
-   warranty of any kind, either expressed, implied, or statutory, including,
-   without limitation, warranties that the Covered Software is free of defects,
-   merchantable, fit for a particular purpose or non-infringing. The entire
-   risk as to the quality and performance of the Covered Software is with You.
-   Should any Covered Software prove defective in any respect, You (not any
-   Contributor) assume the cost of any necessary servicing, repair, or
-   correction. This disclaimer of warranty constitutes an essential part of this
-   License. No use of  any Covered Software is authorized under this License
-   except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from such
-   party’s negligence to the extent applicable law prohibits such limitation.
-   Some jurisdictions do not allow the exclusion or limitation of incidental or
-   consequential damages, so this exclusion and limitation may not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts of
-   a jurisdiction where the defendant maintains its principal place of business
-   and such litigation shall be governed by laws of that jurisdiction, without
-   reference to its conflict-of-law provisions. Nothing in this Section shall
-   prevent a party’s ability to bring cross-claims or counter-claims.
-
-9. Miscellaneous
-
-   This License represents the complete agreement concerning the subject matter
-   hereof. If any provision of this License is held to be unenforceable, such
-   provision shall be reformed only to the extent necessary to make it
-   enforceable. Any law or regulation which provides that the language of a
-   contract shall be construed against the drafter shall not be used to construe
-   this License against a Contributor.
-
-
-10. Versions of the License
-
-10.1. New Versions
-
-      Mozilla Foundation is the license steward. Except as provided in Section
-      10.3, no one other than the license steward has the right to modify or
-      publish new versions of this License. Each version will be given a
-      distinguishing version number.
-
-10.2. Effect of New Versions
-
-      You may distribute the Covered Software under the terms of the version of
-      the License under which You originally received the Covered Software, or
-      under the terms of any subsequent version published by the license
-      steward.
-
-10.3. Modified Versions
-
-      If you create software not governed by this License, and you want to
-      create a new license for such software, you may create and use a modified
-      version of this License if you rename the license and remove any
-      references to the name of the license steward (except to note that such
-      modified license differs from this License).
-
-10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
-      If You choose to distribute Source Code Form that is Incompatible With
-      Secondary Licenses under the terms of this version of the License, the
-      notice described in Exhibit B of this License must be attached.

-# logutils
-
-logutils is a Go package that augments the standard library "log" package
-to make logging a bit more modern, without fragmenting the Go ecosystem
-with new logging packages.
-
-## The simplest thing that could possibly work
-
-Presumably your application already uses the default `log` package. To switch, you'll want your code to look like the following:
-
-```go
-package main
-
-import (
-	"log"
-	"os"
-
-	"github.com/hashicorp/logutils"
-)
-
-func main() {
-	filter := &logutils.LevelFilter{
-		Levels: []logutils.LogLevel{"DEBUG", "WARN", "ERROR"},
-		MinLevel: logutils.LogLevel("WARN"),
-		Writer: os.Stderr,
-	}
-	log.SetOutput(filter)
-
-	log.Print("[DEBUG] Debugging") // this will not print
-	log.Print("[WARN] Warning") // this will
-	log.Print("[ERROR] Erring") // and so will this
-	log.Print("Message I haven't updated") // and so will this
-}
-```
-
-This logs to standard error exactly like go's standard logger. Any log messages you haven't converted to have a level will continue to print as before.
