Re: [Texmacs-dev] langle in text export

[Sam Liddicott]

I've loosely contrived this command: except-specific-verbatim

<assign|except-specific-verbatim|<macro|body|<specific|screen|<arg|body>><specific|printer|<arg|body>><if*|false|<arg|body>>>>

Which tries to render for output except verbatim output. It works 
because <if*|false|...> doesn't reserve space for verbatim export.

Where I have been using langle I now use:
<except-specific-verbatim|<with|mode|math|<left|langle>>>

And thus manage to squash its appearance.

More generally, nv-langle and nv-rangle can have overridable 
substitution characters used in verbatim mode:

<assign|specific-verbatim|<macro|x|<with|color|white|magnification|0.01|<arg|x>>>>

<assign|except-specific-verbatim|<macro|body|<specific|screen|<arg|body>><specific|printer|<arg|body>><if*|false|<arg|body>>>>

<assign|nv-langle-subst|\<less\>>

<assign|nv-rangle-subst|\<gtr\>>

<assign|nv-langle|<macro|<except-specific-verbatim|<with|mode|math|<left|langle>>><if|<provides|nv-langle-subst>|<specific-verbatim|<value|nv-langle-subst>>>>>

<assign|nv-rangle|<macro|<except-specific-verbatim|<with|mode|math|<right|rangle>>><if|<provides|nv-rangle-subst>|<specific-verbatim|<value|nv-rangle-subst>>>>>

Is there a better way I could define specific-verbatim to avoid output 
in non-verbatim export? I wish there were an environment variable set 
during rendering...
