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.

Natural map order is used by default. - - * 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. - -Dump Usage - -Simply call spew.Dump with a list of variables you want to dump: - - spew.Dump(myVar1, myVar2, ...) - -You may also call spew.Fdump if you would prefer to output to an arbitrary -io.Writer. For example, to dump to standard error: - - spew.Fdump(os.Stderr, myVar1, myVar2, ...) - -A third option is to call spew.Sdump to get the formatted output as a string: - - str := spew.Sdump(myVar1, myVar2, ...) - -Sample Dump Output - -See the Dump example for details on the setup of the types and variables being -shown here. - - (main.Foo) { - unexportedField: (*main.Bar)(0xf84002e210)({ - flag: (main.Flag) flagTwo, - data: (uintptr) - }), - ExportedField: (map[interface {}]interface {}) (len=1) { - (string) (len=3) "one": (bool) true - } - } - -Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C -command as shown. - ([]uint8) (len=32 cap=32) { - 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| - } - -Custom Formatter - -Spew provides a custom formatter that implements the fmt.Formatter interface -so that it integrates cleanly with standard fmt package printing functions. The -formatter is useful for inline printing of smaller data types similar to the -standard %v format specifier. - -The custom formatter only responds to the %v (most compact), %+v (adds pointer -addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb -combinations. Any other verbs such as %x and %q will be sent to the the -standard fmt package for formatting. In addition, the custom formatter ignores -the width and precision arguments (however they will still work on the format -specifiers not handled by the custom formatter). - -Custom Formatter Usage - -The simplest way to make use of the spew custom formatter is to call one of the -convenience functions such as spew.Printf, spew.Println, or spew.Printf. The -functions have syntax you are most likely already familiar with: - - spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - spew.Println(myVar, myVar2) - spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - -See the Index for the full list convenience functions. - -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 <*>} - %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)} - %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)} - %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)} - -See the Printf example for details on the setup of variables being shown -here. - -Errors - -Since it is possible for custom Stringer/error interfaces to panic, spew -detects them and handles them internally by printing the panic information -inline with the output. Since spew is intended to provide deep pretty printing -capabilities on structures, it intentionally does not return any errors. -*/ -package spew diff --git a/vendor/github.com/davecgh/go-spew/spew/dump.go b/vendor/github.com/davecgh/go-spew/spew/dump.go deleted file mode 100644 index df1d582a7..000000000 --- a/vendor/github.com/davecgh/go-spew/spew/dump.go +++ /dev/null @@ -1,509 +0,0 @@ -/* - * Copyright (c) 2013-2016 Dave Collins - * - * Permission to use, copy, modify, and distribute this software for any - * purpose with or without fee is hereby granted, provided that the above - * copyright notice and this permission notice appear in all copies. - * - * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES - * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF - * MERCHANTABILITY AND FITNESS.
