D.9.2.10 texproc
Procedure from library latex.lib (see latex_lib).
- Usage:
- texproc(fname,pname); fname,pname strings
- Assume:
`pname` is a procedure.
- Return:
- if
fname="": string, the proc `pname` in a verbatim
environment in LaTeX-typesetting;
otherwise: append this string to the file <fname>, and
return nothing.
- Note:
- preceding ">>" are deleted in
fname, and suffix ".tex"
(if not given) is added to fname.
Example:
| | LIB "latex.lib";
texproc("","texproc");
==> \begin{verbatim}
==> proc texproc(string fname,string pname)
==> {
==> int i,j,k,nl;
==> string @p,s,t;
==>
==> j = 1;
==>
==> if (defined(`pname`))
==> { if (typeof(`pname`)=="proc")
==> { @p = string(`pname`);
==> nl = find(@p,newline);
==> s = "\\begin{verbatim}" + newline;
==> s = s + "proc " + pname + "(";
==> i = find(@p,"parameter"); // collecting the parameters
==> k = find(@p,"alias"); // and the alias arguments
==> while((i and i < nl) or (k and k < nl))
==> {
==> if (i and (k==0 or i<k))
==> {
==> j=find(@p,";",i);
==> t = @p[i+10,j-i-10];
==> if(i>1){s = s + ",";};
==> s = s + t;
==> }
==> if (k and (i==0 or k<i))
==> {
==> j=find(@p,";",k);
==> t = @p[k,j-k];
==> if(k>1){s = s + ",";};
==> s = s + t;
==> }
==> i = find(@p,"parameter",j);
==> k = find(@p,"alias",j);
==> }
==> s = s + ")" + newline;
==> j++; // skip one for the newline
==> i = find(@p,";"+"return();"+newline,j);
==> if (!(i))
==> { i = find(@p,";"+"RETURN();"+newline,j); } // j kann hier weg
==> s = s + "{" + @p[j,i-j-1] + "}" + newline;
==> s = s + "\\end{verbatim}" + newline;
==> }
==> }
==> else
==> { print(" // -- Error: No such proc defined");
==> return();
==> }
==> if(size(fname))
==> { i=1;
==> while (fname[i]==">"){i++;}
==> fname = fname[i,size(fname)-i+1];
==> if (size(fname)>=4) // check if filename is ending with ".tex"
==> { if(fname[size(fname)-3,4]!=".tex") {fname = fname +".tex"; }
==> }
==> else {fname = fname + ".tex";}
==> write(fname,s);
==> }
==> else{return(s);}
==> }
==> \end{verbatim}
