how to write two or three single hyphens?

how to write two or three single hyphens?

[Jan Pohanka]

Hello,

describing linux file permissions I would like to write rwx------
As I expected the hyphens are converted to two long dashes (excuse me if I  
missed the correct name), so I tried something like this  
rwx{-}{-}{-}{-}{-}{-} or rwx{}-{}-{}-{}-{}-{}- which works in latex, but  
in context I'm still getting the long dashes. How can I prevent this  
conversion, please?

regards
Jan

Hello,

is this what you are looking for?

\starttext
rwx\,-\,-\,-\,-\,-\,-
\stoptext

I tried the small space macro from LaTeX and it works here, too, so i suspect it is more a TeX macro.

\definehighlight[filepermission][style=\setff{none}]

\starttext

Verbatim: \type{rwx------}

Highlight: \filepermission{rwx------}

\stoptext

Great, thank you. Anyway what is the purpose of the \setff macro? I have  
not found its documentation anywhere. Also why the latex way -{}- does not  
work? It is a feature of luatex?

best regards

-{}- is a side effect of traditional tex

and sort of a hack too

In MkIV you have tell which features of a font (e.g. ligatures or kerning) have to enabled, this is done in two steps.

1. You define a list with the features you want, e.g.

     \definefontfeature[myfeatures][liga=yes,kern=yes]

   which activates ligatures and kerning.

2. You apply this list to a font, normally this is done in the typescripts, e.g.

     \definetypeface[mainface][rm][serif][palatino][default][features=myfeatures]


Sometimes it is necessary to add additional features or to switch a different feature list *in* the document. To do this context provides the commands \addfontfeature and \setfontfeature which can be also called in the two shorter commands \addff and \setff. In the \definehighlight command I enabled the predefined “none” list where ligatures and kerning is disabled to prevent that -- results in –.

{} breaking ligatures is “an accidental feature¹” in traditional TeX
that LuaTeX got rid of.
