TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"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 shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) 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 that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the 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.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide 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 Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
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 solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of 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

# Change Log
|
||||
|
||||
**ATTN**: This project uses [semantic versioning](http://semver.org/).
|
||||
|
||||
## [Unreleased]
|
||||
|
||||
## [1.19.1] - 2016-11-21
|
||||
|
||||
### Fixed
|
||||
|
||||
- Fixes regression introduced in 1.19.0 where using an `ActionFunc` as
|
||||
the `Action` for a command would cause it to error rather than calling the
|
||||
function. Should not have a affected declarative cases using `func(c
|
||||
*cli.Context) err)`.
|
||||
- Shell completion now handles the case where the user specifies
|
||||
`--generate-bash-completion` immediately after a flag that takes an argument.
|
||||
Previously it call the application with `--generate-bash-completion` as the
|
||||
flag value.
|
||||
|
||||
## [1.19.0] - 2016-11-19
|
||||
### Added
|
||||
- `FlagsByName` was added to make it easy to sort flags (e.g. `sort.Sort(cli.FlagsByName(app.Flags))`)
|
||||
- A `Description` field was added to `App` for a more detailed description of
|
||||
the application (similar to the existing `Description` field on `Command`)
|
||||
- Flag type code generation via `go generate`
|
||||
- Write to stderr and exit 1 if action returns non-nil error
|
||||
- Added support for TOML to the `altsrc` loader
|
||||
- `SkipArgReorder` was added to allow users to skip the argument reordering.
|
||||
This is useful if you want to consider all "flags" after an argument as
|
||||
arguments rather than flags (the default behavior of the stdlib `flag`
|
||||
library). This is backported functionality from the [removal of the flag
|
||||
reordering](https://github.com/urfave/cli/pull/398) in the unreleased version
|
||||
2
|
||||
- For formatted errors (those implementing `ErrorFormatter`), the errors will
|
||||
be formatted during output. Compatible with `pkg/errors`.
|
||||
|
||||
### Changed
|
||||
- Raise minimum tested/supported Go version to 1.2+
|
||||
|
||||
### Fixed
|
||||
- Consider empty environment variables as set (previously environment variables
|
||||
with the equivalent of `""` would be skipped rather than their value used).
|
||||
- Return an error if the value in a given environment variable cannot be parsed
|
||||
as the flag type. Previously these errors were silently swallowed.
|
||||
- Print full error when an invalid flag is specified (which includes the invalid flag)
|
||||
- `App.Writer` defaults to `stdout` when `nil`
|
||||
- If no action is specified on a command or app, the help is now printed instead of `panic`ing
|
||||
- `App.Metadata` is initialized automatically now (previously was `nil` unless initialized)
|
||||
- Correctly show help message if `-h` is provided to a subcommand
|
||||
- `context.(Global)IsSet` now respects environment variables. Previously it
|
||||
would return `false` if a flag was specified in the environment rather than
|
||||
as an argument
|
||||
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
|
||||
- `altsrc`s import paths were updated to use `gopkg.in/urfave/cli.v1`. This
|
||||
fixes issues that occurred when `gopkg.in/urfave/cli.v1` was imported as well
|
||||
as `altsrc` where Go would complain that the types didn't match
|
||||
|
||||
## [1.18.1] - 2016-08-28
|
||||
### Fixed
|
||||
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user (backported)
|
||||
|
||||
## [1.18.0] - 2016-06-27
|
||||
### Added
|
||||
- `./runtests` test runner with coverage tracking by default
|
||||
- testing on OS X
|
||||
- testing on Windows
|
||||
- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
|
||||
|
||||
### Changed
|
||||
- Use spaces for alignment in help/usage output instead of tabs, making the
|
||||
output alignment consistent regardless of tab width
|
||||
|
||||
### Fixed
|
||||
- Printing of command aliases in help text
|
||||
- Printing of visible flags for both struct and struct pointer flags
|
||||
- Display the `help` subcommand when using `CommandCategories`
|
||||
- No longer swallows `panic`s that occur within the `Action`s themselves when
|
||||
detecting the signature of the `Action` field
|
||||
|
||||
## [1.17.1] - 2016-08-28
|
||||
### Fixed
|
||||
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
|
||||
|
||||
## [1.17.0] - 2016-05-09
|
||||
### Added
|
||||
- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
|
||||
- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
|
||||
- Support for hiding commands by setting `Hidden: true` -- this will hide the
|
||||
commands in help output
|
||||
|
||||
### Changed
|
||||
- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
|
||||
quoted in help text output.
|
||||
- All flag types now include `(default: {value})` strings following usage when a
|
||||
default value can be (reasonably) detected.
|
||||
- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
|
||||
with non-slice flag types
|
||||
- Apps now exit with a code of 3 if an unknown subcommand is specified
|
||||
(previously they printed "No help topic for...", but still exited 0. This
|
||||
makes it easier to script around apps built using `cli` since they can trust
|
||||
that a 0 exit code indicated a successful execution.
|
||||
- cleanups based on [Go Report Card
|
||||
feedback](https://goreportcard.com/report/github.com/urfave/cli)
|
||||
|
||||
## [1.16.1] - 2016-08-28
|
||||
### Fixed
|
||||
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
|
||||
|
||||
## [1.16.0] - 2016-05-02
|
||||
### Added
|
||||
- `Hidden` field on all flag struct types to omit from generated help text
|
||||
|
||||
### Changed
|
||||
- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
|
||||
generated help text via the `Hidden` field
|
||||
|
||||
### Fixed
|
||||
- handling of error values in `HandleAction` and `HandleExitCoder`
|
||||
|
||||
## [1.15.0] - 2016-04-30
|
||||
### Added
|
||||
- This file!
|
||||
- Support for placeholders in flag usage strings
|
||||
- `App.Metadata` map for arbitrary data/state management
|
||||
- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
|
||||
parsing.
|
||||
- Support for nested lookup of dot-delimited keys in structures loaded from
|
||||
YAML.
|
||||
|
||||
### Changed
|
||||
- The `App.Action` and `Command.Action` now prefer a return signature of
|
||||
`func(*cli.Context) error`, as defined by `cli.ActionFunc`. If a non-nil
|
||||
`error` is returned, there may be two outcomes:
|
||||
- If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
|
||||
automatically
|
||||
- Else the error is bubbled up and returned from `App.Run`
|
||||
- Specifying an `Action` with the legacy return signature of
|
||||
`func(*cli.Context)` will produce a deprecation message to stderr
|
||||
- Specifying an `Action` that is not a `func` type will produce a non-zero exit
|
||||
from `App.Run`
|
||||
- Specifying an `Action` func that has an invalid (input) signature will
|
||||
produce a non-zero exit from `App.Run`
|
||||
|
||||
### Deprecated
|
||||
- <a name="deprecated-cli-app-runandexitonerror"></a>
|
||||
`cli.App.RunAndExitOnError`, which should now be done by returning an error
|
||||
that fulfills `cli.ExitCoder` to `cli.App.Run`.
|
||||
- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
|
||||
`cli.App.Action` of `func(*cli.Context)`, which should now have a return
|
||||
signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
|
||||
|
||||
### Fixed
|
||||
- Added missing `*cli.Context.GlobalFloat64` method
|
||||
|
||||
## [1.14.0] - 2016-04-03 (backfilled 2016-04-25)

||||

|
||||

|
||||

"""
|
||||
The flag types that ship with the cli library have many things in common, and
|
||||
so we can take advantage of the `go generate` command to create much of the
|
||||
source code from a list of definitions. These definitions attempt to cover
|
||||
the parts that vary between flag types, and should evolve as needed.
|
||||
|
||||
An example of the minimum definition needed is:
|
||||
|
||||
{
|
||||
"name": "SomeType",
|
||||
"type": "sometype",
|
||||
"context_default": "nil"
|
||||
}
|
||||
|
||||
In this example, the code generated for the `cli` package will include a type
|
||||
named `SomeTypeFlag` that is expected to wrap a value of type `sometype`.
|
||||
Fetching values by name via `*cli.Context` will default to a value of `nil`.
|
||||
|
||||
A more complete, albeit somewhat redundant, example showing all available
|
||||
definition keys is:
|
||||
|
||||
{
|
||||
"name": "VeryMuchType",
|
||||
"type": "*VeryMuchType",
|
||||
"value": true,
|
||||
"dest": false,
|
||||
"doctail": " which really only wraps a []float64, oh well!",
|
||||
"context_type": "[]float64",
|
||||
"context_default": "nil",
|
||||
"parser": "parseVeryMuchType(f.Value.String())",
|
||||
"parser_cast": "[]float64(parsed)"
|
||||
}
|
||||
|
||||
The meaning of each field is as follows:
|
||||
|
||||
name (string) - The type "name", which will be suffixed with
|
||||
`Flag` when generating the type definition
|
||||
for `cli` and the wrapper type for `altsrc`
|
||||
type (string) - The type that the generated `Flag` type for `cli`
|
||||
is expected to "contain" as its `.Value` member
|
||||
value (bool) - Should the generated `cli` type have a `Value`
|
||||
member?
|
||||
dest (bool) - Should the generated `cli` type support a
|
||||
destination pointer?
|
||||
doctail (string) - Additional docs for the `cli` flag type comment
|
||||
context_type (string) - The literal type used in the `*cli.Context`
|
||||
reader func signature
|
||||
context_default (string) - The literal value used as the default by the
|
||||
`*cli.Context` reader funcs when no value is
|
||||
present
|
||||
parser (string) - Literal code used to parse the flag `f`,
|
||||
expected to have a return signature of
|
||||
(value, error)
|
||||
parser_cast (string) - Literal code used to cast the `parsed` value
|
||||
returned from the `parser` code

# pty
|
||||
|
||||
Pty is a Go package for using unix pseudo-terminals.
|
||||
|
||||
## Install
|
||||
|
||||
go get github.com/creack/pty
|
||||
|
||||
## Example
|
||||
|
||||
### Command
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/creack/pty"
|
||||
"io"
|
||||
"os"
|
||||
"os/exec"
|
||||
)
|
||||
|
||||
func main() {
|
||||
c := exec.Command("grep", "--color=auto", "bar")
|
||||
f, err := pty.Start(c)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
go func() {
|
||||
f.Write([]byte("foo\n"))
|
||||
f.Write([]byte("bar\n"))
|
||||
f.Write([]byte("baz\n"))
|
||||
f.Write([]byte{4}) // EOT
|
||||
}()
|
||||
io.Copy(os.Stdout, f)
|
||||
}
|
||||
```
|
||||
|

// Write buffers are also used for constructing WebSocket frames. See RFC 6455,
|
||||
// Section 5 for a discussion of message framing. A WebSocket frame header is
|
||||
// written to the network each time a write buffer is flushed to the network.
|
||||
// Decreasing the size of the write buffer can increase the amount of framing
|
||||
// overhead on the connection.
|
||||
//
|
||||
// The buffer sizes in bytes are specified by the ReadBufferSize and
|
||||
// WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default
|
||||
// size of 4096 when a buffer size field is set to zero. The Upgrader reuses
|
||||
// buffers created by the HTTP server when a buffer size field is set to zero.
|
||||
// The HTTP server buffers have a size of 4096 at the time of this writing.
|
||||
//
|
||||
// The buffer sizes do not limit the size of a message that can be read or
|
||||
// written by a connection.
|
||||
//
|
||||
// Buffers are held for the lifetime of the connection by default. If the
|
||||
// Dialer or Upgrader WriteBufferPool field is set, then a connection holds the
|
||||
// write buffer only when writing a message.
|
||||
//
|
||||
// Applications should tune the buffer sizes to balance memory use and
|
||||
// performance. Increasing the buffer size uses more memory, but can reduce the
|
||||
// number of system calls to read or write the network. In the case of writing,
|
||||
// increasing the buffer size can reduce the number of frame headers written to
|
||||
// the network.
|
||||
//
|
||||
// Some guidelines for setting buffer parameters are:
|
||||
//
|
||||
// Limit the buffer sizes to the maximum expected message size. Buffers larger
|
||||
// than the largest message do not provide any benefit.
|
||||
//
|
||||
// Depending on the distribution of message sizes, setting the buffer size to
|
||||
// to a value less than the maximum expected message size can greatly reduce
|
||||
// memory use with a small impact on performance. Here's an example: If 99% of
|
||||
// the messages are smaller than 256 bytes and the maximum message size is 512
|
||||
// bytes, then a buffer size of 256 bytes will result in 1.01 more system calls
|
||||
// than a buffer size of 512 bytes. The memory savings is 50%.
|
||||
//
|
||||
// A write buffer pool is useful when the application has a modest number
|
||||
// writes over a large number of connections. when buffers are pooled, a larger
|
||||
// buffer size has a reduced impact on total memory use and has the benefit of
|
||||
// reducing system calls and frame overhead.
|
||||
//
|
||||
// Compression EXPERIMENTAL
|
||||
//
|
||||
// Per message compression extensions (RFC 7692) are experimentally supported
|
||||
// by this package in a limited capacity. Setting the EnableCompression option
|
||||
// to true in Dialer or Upgrader will attempt to negotiate per message deflate
|
||||
// support.
|
||||
//
|
||||
// var upgrader = websocket.Upgrader{
|
||||
// EnableCompression: true,
|
||||
// }
|
||||
//
|
||||
// If compression was successfully negotiated with the connection's peer, any
|
||||
// message received in compressed form will be automatically decompressed.
|
||||
// All Read methods will return uncompressed bytes.
|
||||
//
|
||||
// Per message compression of messages written to a connection can be enabled
|
||||
// or disabled by calling the corresponding Conn method:
|
||||
//
|
||||
// conn.EnableWriteCompression(false)
|
||||
//
|
||||
// Currently this package does not support compression with "context takeover".
|
||||
// This means that messages must be compressed and decompressed in isolation,
|
||||
// without retaining sliding window or dictionary state across messages. For
|
||||
// more details refer to RFC 7692.
|
||||
//
|
||||
// Use of compression is experimental and may result in decreased performance.

|
||||
Each Contributor hereby grants You a world-wide, royalty-free,
|
||||
non-exclusive license:
|
||||
|
||||
a. under intellectual property rights (other than patent or trademark)
|
||||
Licensable by such Contributor to use, reproduce, make available,

||||
|
||||
2.2. Effective Date
|
||||
|
||||

|
||||
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
|

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

||||
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

# errwrap
|
||||
|
||||
`errwrap` is a package for Go that formalizes the pattern of wrapping errors
|
||||
and checking if an error contains another error.
|
||||
|
||||
There is a common pattern in Go of taking a returned `error` value and
|
||||
then wrapping it (such as with `fmt.Errorf`) before returning it. The problem
|
||||
with this pattern is that you completely lose the original `error` structure.
|
||||
|
||||
Arguably the _correct_ approach is that you should make a custom structure
|
||||
implementing the `error` interface, and have the original error as a field
|
||||
on that structure, such [as this example](http://golang.org/pkg/os/#PathError).
|
||||
This is a good approach, but you have to know the entire chain of possible
|
||||
rewrapping that happens, when you might just care about one.
|
||||
|
||||
`errwrap` formalizes this pattern (it doesn't matter what approach you use
|
||||
above) by giving a single interface for wrapping errors, checking if a specific
|
||||
error is wrapped, and extracting that error.
|
||||
|
||||
## Installation and Docs
|
||||
|
||||
Install using `go get github.com/hashicorp/errwrap`.
|
||||
|
||||
Full documentation is available at
|
||||
http://godoc.org/github.com/hashicorp/errwrap
|
||||
|
||||
## Usage
|
||||
|
||||
#### Basic Usage
|
||||
|
||||
Below is a very basic example of its usage:
|
||||
|
||||
```go
|
||||
// A function that always returns an error, but wraps it, like a real
|
||||
// function might.
|
||||
func tryOpen() error {
|
||||
_, err := os.Open("/i/dont/exist")
|
||||
if err != nil {
|
||||
return errwrap.Wrapf("Doesn't exist: {{err}}", err)
|
||||
}
|
||||
|
||||
return nil
|
||||
}
|
||||
|
||||
func main() {
|
||||
err := tryOpen()
|
||||
|
||||
// We can use the Contains helpers to check if an error contains
|
||||
// another error. It is safe to do this with a nil error, or with
|
||||
// an error that doesn't even use the errwrap package.
|
||||
if errwrap.Contains(err, "does not exist") {
|
||||
// Do something
|
||||
}
|
||||
if errwrap.ContainsType(err, new(os.PathError)) {
|
||||
// Do something
|
||||
}
|
||||
|
||||
// Or we can use the associated `Get` functions to just extract
|
||||
// a specific error. This would return nil if that specific error doesn't
|
||||
// exist.
|
||||
perr := errwrap.GetType(err, new(os.PathError))
|
||||
}
|
||||
```
|
||||
|
||||
#### Custom Types
|
||||
|
||||
If you're already making custom types that properly wrap errors, then
|
||||
you can get all the functionality of `errwraps.Contains` and such by
|
||||
implementing the `Wrapper` interface with just one function. Example:
|
||||
|
||||
```go
|
||||
type AppError {
|
||||
Code ErrorCode
|
||||
Err error
|
||||
}
|
||||
|
||||
func (e *AppError) WrappedErrors() []error {
|
||||
return []error{e.Err}
|
||||
}
|
||||
```
|
||||
|
||||
Now this works:
|
||||
|
||||
```go
|
||||
err := &AppError{Err: fmt.Errorf("an error")}
|
||||
if errwrap.ContainsType(err, fmt.Errorf("")) {
|
||||
// This will work!
|
||||
}
|
||||
```
