||||
|
||||
* [PR #26](https://github.com/magiconair/properties/pull/35): Close body always after request

# 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.
|
||||
|
||||
Read the full documentation on [](http://godoc.org/github.com/magiconair/properties)
|
||||
|
||||
## 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)
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||

## ToDo
|
||||
|
||||
* Dump contents with passwords and secrets obscured
|
||||
|
||||
## 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.
