|
||||
## Issues
|
||||
|
||||
* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues).
|
||||
* Please indicate the platform you are using fsnotify on.
|
||||
* A code example to reproduce the problem is appreciated.
|
||||
|
||||
## Pull Requests
|
||||
|
||||
### Contributor License Agreement
|
||||
|
||||
fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual).
|
||||
|
||||
Please indicate that you have signed the CLA in your pull request.
|
||||
|
||||
### How fsnotify is Developed
|
||||
|
||||
* Development is done on feature branches.
|
||||
* Tests are run on BSD, Linux, macOS and Windows.
|
||||
* Pull requests are reviewed and [applied to master][am] using [hub][].
|
||||
* Maintainers may modify or squash commits rather than asking contributors to.
|
||||
* To issue a new release, the maintainers will:
|
||||
* Update the CHANGELOG
|
||||
* Tag a version, which will become available through gopkg.in.
|
||||
|
||||
### How to Fork
|
||||
|
||||
For smooth sailing, always use the original import path. Installing with `go get` makes this easy.
|
||||
|
||||
1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`)
|
||||
2. Create your feature branch (`git checkout -b my-new-feature`)
|
||||
3. Ensure everything works and the tests pass (see below)
|
||||
4. Commit your changes (`git commit -am 'Add some feature'`)
|
||||
|
||||
Contribute upstream:
|
||||
|
||||
1. Fork fsnotify on GitHub
|
||||
2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`)
|
||||
3. Push to the branch (`git push fork my-new-feature`)
|
||||
4. Create a new Pull Request on GitHub
|
||||
|
||||
This workflow is [thoroughly explained by Katrina Owen](https://splice.com/blog/contributing-open-source-git-repositories-go/).
|
||||
|
||||
### Testing
|
||||
|
||||
fsnotify uses build tags to compile different code on Linux, BSD, macOS, and Windows.
|
||||
|
||||
Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
|
||||
|
||||
To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
|
||||
|
||||
* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
|
||||
* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
|
||||
* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
|
||||
* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
|
||||
* When you're done, you will want to halt or destroy the Vagrant boxes.
|
||||
|
||||
Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
|
||||
|
||||
Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).
|
||||
|
||||
### Maintainers
|
||||
|
||||
Help maintaining fsnotify is welcome. To be a maintainer:
|
||||
|
||||
* Submit a pull request and sign the CLA as above.
|
||||
* You must be able to run the test suite on Mac, Windows, Linux and BSD.
|
||||
|
||||
To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][].
|
||||
|
||||
All code changes should be internal pull requests.
|
||||
|
||||
Releases are tagged using [Semantic Versioning](http://semver.org/).

# File system notifications for Go
|
||||
|
||||
[](https://godoc.org/github.com/fsnotify/fsnotify) [](https://goreportcard.com/report/github.com/fsnotify/fsnotify)
|
||||
|
||||
fsnotify utilizes [golang.org/x/sys](https://godoc.org/golang.org/x/sys) rather than `syscall` from the standard library. Ensure you have the latest version installed by running:
|
||||
|
||||
```console
|
||||
go get -u golang.org/x/sys/...
|
||||
```
|
||||
|
||||
Cross platform: Windows, Linux, BSD and macOS.
|
||||
|
||||

Please see [the documentation](https://godoc.org/github.com/fsnotify/fsnotify) and consult the [FAQ](#faq) for usage information.
|
||||
|
||||
## API stability
|
||||
|
||||
fsnotify is a fork of [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA).
|
||||
|
||||
All [releases](https://github.com/fsnotify/fsnotify/releases) are tagged based on [Semantic Versioning](http://semver.org/). Further API changes are [planned](https://github.com/fsnotify/fsnotify/milestones), and will be tagged with a new major revision number.
|
||||
|
||||
Go 1.6 supports dependencies located in the `vendor/` folder. Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`.
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
|

## FAQ
|
||||
|
||||
**When a file is moved to another directory is it still being watched?**
|
||||
|
||||
No (it shouldn't be, unless you are watching where it was moved to).
|
||||
|
||||
**When I watch a directory, are all subdirectories watched as well?**
|
||||
|
||||
No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]).
|
||||
|
||||
**Do I have to watch the Error and Event channels in a separate goroutine?**
|
||||
|
||||
As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7])
|
||||
|
||||
**Why am I receiving multiple events for the same file on OS X?**
|
||||
|
||||
Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]).
|
||||
|
||||
**How many files can be watched at once?**
|
||||
|
||||
There are OS-specific limits as to how many watches can be created:
|
||||
* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error.
|
||||
* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.
|
||||
|
||||
**Why don't notifications work with NFS filesystems or filesystem in userspace (FUSE)?**
|
||||
|
||||
fsnotify requires support from underlying OS to work. The current NFS protocol does not provide network level support for file notifications.

2. License Grants and Conditions
|
||||
|
||||
2.1. Grants
|
||||
|
||||
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,
|
||||
modify, display, perform, distribute, and otherwise exploit its
|
||||
Contributions, either on an unmodified basis, with Modifications, or as
|
||||
part of a Larger Work; and
|
||||
|
||||
b. under Patent Claims of such Contributor to make, use, sell, offer for
|
||||
sale, have made, import, and otherwise transfer either its Contributions
|
||||
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.
|
||||
|
||||
Exhibit A - Source Code Form License Notice
|
||||
|
||||
This Source Code Form is subject to the
|
||||
terms of the Mozilla Public License, v.
|
||||
2.0. If a copy of the MPL was not
|
||||
distributed with this file, You can
|
||||
obtain one at
|
||||
http://mozilla.org/MPL/2.0/.
|
||||
|
||||
If it is not possible or desirable to put the notice in a particular file, then
|
||||
You may include the notice in a location (such as a LICENSE file in a relevant
|
||||
directory) where a recipient would be likely to look for such a notice.
|
||||
|
||||
You may add additional accurate notices of copyright ownership.

# HCL
|
||||
|
||||
[](https://godoc.org/github.com/hashicorp/hcl) [](https://travis-ci.org/hashicorp/hcl)
|
||||
|
||||
HCL (HashiCorp Configuration Language) is a configuration language built
|
||||
by HashiCorp. The goal of HCL is to build a structured configuration language
|
||||
that is both human and machine friendly for use with command-line tools, but
|
||||
specifically targeted towards DevOps tools, servers, etc.
|
||||
|
||||
HCL is also fully JSON compatible. That is, JSON can be used as completely
|
||||
valid input to a system expecting HCL. This helps makes systems
|
||||
interoperable with other systems.
|
||||
|
||||
HCL is heavily inspired by
|
||||
[libucl](https://github.com/vstakhov/libucl),
|
||||
nginx configuration, and others similar.
|
||||
|
||||
## Why?
|
||||
|
||||
A common question when viewing HCL is to ask the question: why not
|
||||
JSON, YAML, etc.?
|
||||
|
||||
Prior to HCL, the tools we built at [HashiCorp](http://www.hashicorp.com)
|
||||
used a variety of configuration languages from full programming languages
|
||||
such as Ruby to complete data structure languages such as JSON. What we
|
||||
learned is that some people wanted human-friendly configuration languages
|
||||
and some people wanted machine-friendly languages.
|
||||
|
||||
JSON fits a nice balance in this, but is fairly verbose and most
|
||||
importantly doesn't support comments. With YAML, we found that beginners
|
||||
had a really hard time determining what the actual structure was, and
|
||||
ended up guessing more often than not whether to use a hyphen, colon, etc.
|
||||
in order to represent some configuration key.
|
||||
|
||||
Full programming languages such as Ruby enable complex behavior
|
||||
a configuration language shouldn't usually allow, and also forces
|
||||
people to learn some set of Ruby.
|
||||
|
||||
Because of this, we decided to create our own configuration language
|
||||
that is JSON-compatible. Our configuration language (HCL) is designed
|
||||
to be written and modified by humans. The API for HCL allows JSON
|
||||
as an input so that it is also machine-friendly (machines can generate
|
||||
JSON instead of trying to generate HCL).
|
||||
|
||||
Our goal with HCL is not to alienate other configuration languages.
|
||||
It is instead to provide HCL as a specialized language for our tools,
|
||||
and JSON as the interoperability layer.
|
||||
|
||||
## Syntax
|
||||
|
||||
For a complete grammar, please see the parser itself. A high-level overview
|
||||
of the syntax and grammar is listed here.
|
||||
|
||||
* Single line comments start with `#` or `//`
|
||||
|
||||
* Multi-line comments are wrapped in `/*` and `*/`. Nested block comments
|
||||
are not allowed. A multi-line comment (also known as a block comment)
|
||||
terminates at the first `*/` found.
|
||||
|
||||
* Values are assigned with the syntax `key = value` (whitespace doesn't
|
||||
matter). The value can be any primitive: a string, number, boolean,
|
||||
object, or list.
|
||||
|
||||
* Strings are double-quoted and can contain any UTF-8 characters.
|
||||
Example: `"Hello, World"`
|
||||
|
||||
* Multi-line strings start with `<<EOF` at the end of a line, and end
|
||||
with `EOF` on its own line ([here documents](https://en.wikipedia.org/wiki/Here_document)).
|
||||
Any text may be used in place of `EOF`. Example:
|
||||
```
|
||||
<<FOO
|
||||
hello
|
||||
world
|
||||
FOO
|
||||
```
|
||||
|
||||
* Numbers are assumed to be base 10. If you prefix a number with 0x,
|
||||
it is treated as a hexadecimal. If it is prefixed with 0, it is
|
||||
treated as an octal. Numbers can be in scientific notation: "1e10".
|
||||
|
||||
* Boolean values: `true`, `false`
|
||||
|
||||
* Arrays can be made by wrapping it in `[]`. Example:
|
||||
`["foo", "bar", 42]`. Arrays can contain primitives,
|
||||
other arrays, and objects. As an alternative, lists
|
||||
of objects can be created with repeated blocks, using
|
||||
this structure:
|
||||
|
||||
```hcl
|
||||
service {
|
||||
key = "value"
|
||||
}
|
||||
|
||||
service {
|
||||
key = "value"
|
||||
}
|
||||
```
|
||||
|
||||
Objects and nested objects are created using the structure shown below:
|
||||
|
||||
```
|
||||
variable "ami" {
|
||||
description = "the AMI to use"
|
||||
}
|
||||
```
|
||||
This would be equivalent to the following json:
|
||||
``` json
|
||||
{
|
||||
"variable": {
|
||||
"ami": {
|
||||
"description": "the AMI to use"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
in pure Go (no goyacc) and support for a printer.

|
||||
form, that is based on (or derived from) the Work and for which the
|

|
||||
by such Contributor that are necessarily infringed by their

granted to You under this License for that Work shall terminate
|
||||

|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without

Derivative Works a copy of this License; 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
|
||||
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.

# mousetrap
|
||||
|
||||
mousetrap is a tiny library that answers a single question.
|
||||
|
||||
On a Windows machine, was the process invoked by someone double clicking on
|
||||
the executable file while browsing in explorer?
|
||||
|
||||
### Motivation
|
||||
|
||||
Windows developers unfamiliar with command line tools will often "double-click"
|
||||
the executable for a tool. Because most CLI tools print the help and then exit
|
||||
when invoked without arguments, this is often very frustrating for those users.
|
||||
|
||||
mousetrap provides a way to detect these invocations so that you can provide
|
||||
more helpful behavior and instructions on how to run the CLI tool. To see what
|
||||
this looks like, both from an organizational and a technical perspective, see
|
||||
https://inconshreveable.com/09-09-2014/sweat-the-small-stuff/

# Overview
|
||||
|
||||
#### Please run `git pull --tags` to update the tags. See [below](#updated-git-tags) why.
|
||||
|
||||
properties is a Go library for reading and writing properties files.
|
||||
|
||||
It supports reading from multiple files or URLs and Spring style recursive
|
||||
property expansion of expressions like `${key}` to their corresponding value.
|
||||
Value expressions can refer to other keys like in `${key}` or to environment
|
||||
variables like in `${USER}`. Filenames can also contain environment variables
|
||||
like in `/home/${USER}/myapp.properties`.
|
||||
|
||||
Properties can be decoded into structs, maps, arrays and values through
|
||||
struct tags.
|
||||
|
||||
Comments and the order of keys are preserved. Comments can be modified
|
||||
and can be written to the output.
|
||||
|
||||
The properties library supports both ISO-8859-1 and UTF-8 encoded data.
|
||||
|
||||
Starting from version 1.3.0 the behavior of the MustXXX() functions is
|
||||
configurable by providing a custom `ErrorHandler` function. The default has
|
||||
changed from `panic` to `log.Fatal` but this is configurable and custom
|
||||
error handling functions can be provided. See the package documentation for
|
||||
details.
|
||||

||||

## Getting Started
|
||||
|
||||
```go
|
||||
import (
|
||||
"flag"
|
||||
"github.com/magiconair/properties"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// init from a file
|
||||
p := properties.MustLoadFile("${HOME}/config.properties", properties.UTF8)
|
||||
|
||||
// or multiple files
|
||||
p = properties.MustLoadFiles([]string{
|
||||
"${HOME}/config.properties",
|
||||
"${HOME}/config-${USER}.properties",
|
||||
}, properties.UTF8, true)
|
||||
|
||||
// or from a map
|
||||
p = properties.LoadMap(map[string]string{"key": "value", "abc": "def"})
|
||||
|
||||
// or from a string
|
||||
p = properties.MustLoadString("key=value\nabc=def")
|
||||
|
||||
// or from a URL
|
||||
p = properties.MustLoadURL("http://host/path")
|
||||
|
||||
// or from multiple URLs
|
||||
p = properties.MustLoadURL([]string{
|
||||
"http://host/config",
|
||||
"http://host/config-${USER}",
|
||||
}, true)
|
||||
|
||||
// or from flags
|
||||
p.MustFlag(flag.CommandLine)
|
||||
|
||||
// get values through getters
|
||||
host := p.MustGetString("host")
|
||||
port := p.GetInt("port", 8080)
|
||||
|
||||
// or through Decode
|
||||
type Config struct {
|
||||
Host string `properties:"host"`
|
||||
Port int `properties:"port,default=9000"`
|
||||
Accept []string `properties:"accept,default=image/png;image;gif"`
|
||||
Timeout time.Duration `properties:"timeout,default=5s"`
|
||||
}
|
||||
var cfg Config
|
||||
if err := p.Decode(&cfg); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
}
|
||||
|
||||
```

## Updated Git tags
|
||||
|
||||
#### 13 Feb 2018
|
||||
|
||||
I realized that all of the git tags I had pushed before v1.7.5 were lightweight tags
|
||||
and I've only recently learned that this doesn't play well with `git describe` 😞
|
||||
|
||||
I have replaced all lightweight tags with signed tags using this script which should
|
||||
retain the commit date, name and email address. Please run `git pull --tags` to update them.
|
||||
|
||||
Worst case you have to reclone the repo.
|
||||
|
||||
```shell
|
||||
#!/bin/bash
|
||||
tag=$1
|
||||
echo "Updating $tag"
|
||||
date=$(git show ${tag}^0 --format=%aD | head -1)
|
||||
email=$(git show ${tag}^0 --format=%aE | head -1)
|
||||
name=$(git show ${tag}^0 --format=%aN | head -1)
|
||||
GIT_COMMITTER_DATE="$date" GIT_COMMITTER_NAME="$name" GIT_COMMITTER_EMAIL="$email" git tag -s -f ${tag} ${tag}^0 -m ${tag}
|
||||
```
|
||||
|
||||
I apologize for the inconvenience.

||||

# Mfxkit
|
||||
|
||||
Mfxkit service provides a barebones HTTP API and Service interface implementation for development of a core Mainflux service.
|
||||
|
||||
## Configuration
|
||||
|
||||
The service is configured using the environment variables from the following table. Note that any unset variables will be replaced with their default values.
|
||||
|
||||
| Variable | Description | Default |
|
||||
|-----------------------|---------------------------------------------------------|---------|
|
||||
| MF_MFXKIT_LOG_LEVEL | Log level for mfxkit service (debug, info, warn, error) | error |
|
||||
| MF_MFXKIT_HTTP_PORT | Mfxkit service HTTP port | 9021 |
|
||||
| MF_MFXKIT_SERVER_CERT | Path to server certificate in pem format | |
|
||||
| MF_MFXKIT_SERVER_KEY | Path to server key in pem format | |
|
||||
| MF_JAEGER_URL | Jaeger server URL | |
|
||||
| MF_MFXKIT_SECRET | Mfxkit service secret | secret |
|
||||
|
||||
## Deployment
|
||||
|
||||
The service is distributed as a Docker container. The following snippet provides a compose file template that can be used to deploy the service container locally:
|
||||
|
||||
```yaml
|
||||
version: "3"
|
||||
services:
|
||||
mfxkit:
|
||||
image: mainflux/mfxkit:[version]
|
||||
container_name: [instance name]
|
||||
ports:
|
||||
- [host machine port]:[configured HTTP port]
|
||||
environment:
|
||||
MF_MFXKIT_LOG_LEVEL: [Kit log level]
|
||||
MF_MFXKIT_HTTP_PORT: [Service HTTP port]
|
||||
MF_MFXKIT_SERVER_CERT: [String path to server cert in pem format]
|
||||
MF_MFXKIT_SERVER_KEY: [String path to server key in pem format]
|
||||
MF_MFXKIT_SECRET: [Mfxkit service secret]
|
||||
MF_JAEGER_URL: [Jaeger server URL]
|
||||
```
|
||||
|
||||
To start the service outside of the container, execute the following shell script:
|
||||
|
||||
```bash
|
||||
# download the latest version of the service
|
||||
go get github.com/mainflux/mainflux
|
||||
|
||||
cd $GOPATH/src/github.com/mainflux/mainflux
|
||||
|
||||
# compile the mfxkit
|
||||
make mfxkit
|
||||
|
||||
# copy binary to bin
|
||||
make install
|
||||
|
||||
# set the environment variables and run the service
|
||||

# mapstructure [](https://godoc.org/github.com/mitchellh/mapstructure)
|
||||
|
||||
mapstructure is a Go library for decoding generic map values to structures
|
||||
and vice versa, while providing helpful error handling.
|
||||
|
||||
This library is most useful when decoding values from some data stream (JSON,
|
||||
Gob, etc.) where you don't _quite_ know the structure of the underlying data
|
||||
until you read a part of it. You can therefore read a `map[string]interface{}`
|
||||
and use this library to decode it into the proper underlying native Go
|
||||
structure.
|
||||
|
||||
## Installation
|
||||
|
||||
Standard `go get`:
|
||||
|
||||
```
|
||||
$ go get github.com/mitchellh/mapstructure
|
||||
```
|
||||
|
||||
## Usage & Example
|
||||
|
||||
For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
|
||||
|
||||
The `Decode` function has examples associated with it there.
|
||||
|
||||
## But Why?!
|
||||
|
||||
Go offers fantastic standard libraries for decoding formats such as JSON.
|
||||
The standard method is to have a struct pre-created, and populate that struct
|
||||
from the bytes of the encoded format. This is great, but the problem is if
|
||||
you have configuration or an encoding that changes slightly depending on
|
||||
specific fields. For example, consider this JSON:
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "person",
|
||||
"name": "Mitchell"
|
||||
}
|
||||
```
|
||||
|
||||
Perhaps we can't populate a specific structure without first reading
|
||||
the "type" field from the JSON. We could always do two passes over the
|
||||
decoding of the JSON (reading the "type" first, and the rest later).
|
||||
However, it is much simpler to just decode this into a `map[string]interface{}`
|
||||
structure, read the "type" key, then use something like this library
|
||||
to decode it into the proper structure.
