```go-html-template
|
|
{{ trim "++foo--" "+-" }} → foo
|
|
```
|
|
|
|
To remove leading and trailing newline characters and carriage returns:
|
|
|
|
```go-html-template
|
|
{{ trim "\nfoo\n" "\n\r" }} → foo
|
|
{{ trim "\n\nfoo\n\n" "\n\r" }} → foo
|
|
|
|
{{ trim "\r\nfoo\r\n" "\n\r" }} → foo
|
|
{{ trim "\r\n\r\nfoo\r\n\r\n" "\n\r" }} → foo
|
|
```
|
|
|
|
The `strings.Trim` function is commonly used in shortcodes to remove leading and trailing newlines characters and carriage returns from the content within the opening and closing shortcode tags.
|
|
|
|
For example, with this markdown:
|
|
|
|
```text
|
|
{{</* my-shortcode */>}}
|
|
Able was I ere I saw Elba.
|
|
{{</* /my-shortcode */>}}
|
|
```
|
|
|
|
The value of `.Inner` in the shortcode template is:
|
|
|
|
```text
|
|
\nAble was I ere I saw Elba.\n
|
|
```
|
|
|
|
If authored on a Windows system the value of `.Inner` might, depending on the editor configuration, be:
|
|
|
|
```text
|
|
\r\nAble was I ere I saw Elba.\r\n
|
|
```
|
|
|
|
This construct is common in shortcode templates:
|
|
|
|
```go-html-template
|
|
{{ trim .Inner "\n\r" }}
|
|
```
