Prevent emdash replacing 2 dashes?

[amreus]

I'm playing with an idea of a command-line builder where I can build the command line using a form and copy the command to the clipboard.

Most commands accept 2 dashes for long options but in my example (attached) the double-dashes get converted to an emdash. Can this be prevented?

Thanks.

Hi @amreus, I tried your file on tiddlywiki.com ... try the following code:

<pre><$text text={{!!cmd}}/></pre>
<$wikify name=a text="""<$text text={{!!cmd}}/>""">
<$macrocall $name="copy-to-clipboard" src=<<a>>/>
</$wikify>
<table>
<tr><td>Days:</td><td><$edit-text field="old"/></td></tr>
<tr><td>Depth:</td><td><$edit-text field=depth/></td></tr>
</table>

@@font-family: mono;
cmd: <$text text={{!!cmd}}/>

@amreus - sorry I overlooked that this breaks the wikification of {{!!cmd}}

The promotion of -- to – is caused by a parse rule, called dash. If you're willing to turn it off for this entire wiki, you can find the option in Control Panel/Info/Advanced/Parsing (note that you have to reload the page to see the change).

Otherwise...normally, you can disable parse rules on a tiddler-by-tiddler basis with the \rules except pragma, like:

```

\rules except dash

This will be two hyphens: --

```

I could not get this to work in combination with the $wikify widget though, either by just putting the widget inside a tiddler with a rules pragma or by using a macro to concatenate the pragma to the command before passing it in to $wikify. Maybe there is a way to use pragmas with $wikify that I'm missing, but if so it doesn't appear to be documented.

Thank you, Soren.  Turning the dash option off for the entire wiki seems to be working fine.  If I actually ever need a mdash or ndash, I can use &mdash; and &ndash;

Amreus,

When considering a similar action to generate scripts another method I came across was to open a tiddler displaying a script in a "new window" and Printing the result to a Generic text printer/file. This way you get to name the file as desired and only text.
