## The Future
|
||||
|
||||
### YAML and TOML
|
||||
|
||||
If the community demands the implementation of *getYaml*
|
||||
[YAML](http://yaml.org/) or *getToml* [TOML](https://github.com/toml-lang/toml)
|
||||
these functions will certainly follow.
|
||||
|
||||
### getSql
|
||||
|
||||
The outlook to support more sources is of course implementing SQL support. The following description is an initial idea and may change.
|
||||
|
||||
Maybe adding a new CLI option:
|
||||
|
||||
--sqlSource=path/to/filename.ext
|
||||
|
||||
#### `--sqlSource`
|
||||
|
||||
The file must start with `[mysql|postres|mssql|...]_[\w]+.ext`
|
||||
|
||||
The part before the first underscore specifies the driver to use, which can
|
||||
be one from [https://github.com/golang/go/wiki/SQLDrivers](https://github.com/golang/go/wiki/SQLDrivers).
|
||||
|
||||
The file itself contains only the connection string and no other comments
|
||||
or characters.
|
||||
|
||||
How the connection string looks like depends heavily on the used driver.
|
||||
For MySQL:
|
||||
|
||||
hugo --sqlSource=path/to/mysql_credentials.txt
|
||||
|
||||
The file `mysql_credentials.txt` contains the connection string:
|
||||
`username:password@protocol(address)/dbname?param=value` and nothing more!
|
||||
|
||||
In your template you can process `getSql` the same way as with
|
||||
the `getJson` function:
|
||||
|
||||
{{ $rows := getSql "SELECT id,artist,genre,title FROM musicTable" }}
|
||||
<ul>
|
||||
{{range first 5 $rows }}
|
||||
<li>#{{ .id }} {{.artist}}</a></li>
|
||||
{{end}}
|
||||
</ul>
|
||||
|
||||
Queries with `SELECT * FROM table` are of course also possible but
|
||||
should not be used.
|
||||
Returned **values** will be converted to **strings**.
|
||||
|
||||
Abusing `getSql` with [DML](http://en.wikipedia.org/wiki/Data_manipulation_language)
|
||||
or [DDL](http://en.wikipedia.org/wiki/Data_definition_language) statements
|
||||
causes Hugo to hang up.
