[NTG-context] escaping \ in Lua

[NTG-context] escaping \ in Lua

[Pablo Rodriguez]

Dear list,

I have the following source:

  \setupinteraction[state=start, display=new]
  \enabledirectives[references.border=darkgreen]
  \starttext
  \startTEXpage[offset=1dk]
  \attachment[method=hidden, file=a(b).pdf]
  \stopTEXpage
  \stoptext

The name in EmbeddedFiles is "a\(b\).pdf".

Sorry for the obscure question, but how can I access this with
"\goto{link to external}[a(b).pdf]"?

I guess there may be some Lua magic, but I cannot write a proper
":gsub("%(", "%\%("))".

Many thanks for your help,

Pablo
