# Code blocks
|
|
|
|
Rouge provides lots of different code block "hints". If you leave off the hint,
|
|
it tries to guess and sometimes gets it wrong. These are just a few hints that
|
|
we use often.
|
|
|
|
#### Raw, no highlighting
|
|
|
|
The raw markup is needed to keep Liquid from interpreting the things with double
|
|
braces as templating language.
|
|
|
|
{% raw %}
|
|
```none
|
|
none with raw
|
|
$ some command with {{double braces}}
|
|
$ some other command
|
|
```
|
|
{% endraw %}
|
|
|
|
#### Raw, Bash
|
|
|
|
{% raw %}
|
|
```bash
|
|
bash with raw
|
|
$ some command with {{double braces}}
|
|
$ some other command
|
|
```
|
|
{% endraw %}
|
|
|
|
#### Bash
|
|
|
|
```bash
|
|
$ echo "deb https://packages.docker.com/1.12/apt/repo ubuntu-trusty main" | sudo tee /etc/apt/sources.list.d/docker.list
|
|
```
|
|
|
|
#### Go
|
|
|
|
```go
|
|
incoming := map[string]interface{}{
|
|
"asdf": 1,
|
|
"qwer": []interface{}{},
|
|
"zxcv": []interface{}{
|
|
map[string]interface{}{},
|
|
true,
|
|
int(1e9),
|
|
"tyui",
|
|
},
|
|
}
|
|
```
|
|
|
|
#### PowerShell
|
|
|
|
```powershell
|
|
Install-Module DockerMsftProvider -Force
|
|
Install-Package Docker -ProviderName DockerMsftProvider -Force
|
|
[System.Environment]::SetEnvironmentVariable("DOCKER_FIPS", "1", "Machine")
|
|
Expand-Archive docker-18.09.1.zip -DestinationPath $Env:ProgramFiles -Force
|
|
```
|
|
|
|
#### Python
|
|
|
|
```python
|
|
return html.format(name=os.getenv('NAME', "world"), hostname=socket.gethostname(), visits=visits)
|
|
```
|
|
|
|
#### Ruby
|
|
|
|
```ruby
|
|
docker_service 'default' do
|
|
action [:create, :start]
|
|
end
|
|
```
|
|
|
|
#### JSON
|
|
|
|
```json
|
|
"server": {
|
|
"http_addr": ":4443",
|
|
"tls_key_file": "./fixtures/notary-server.key",
|
|
"tls_cert_file": "./fixtures/notary-server.crt"
|
|
}
|
|
```
|
|
|
|
#### HTML
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<title>Welcome to nginx!</title>
|
|
</head>
