[Gretl-devel] Package maintenance: string & install

Dear Gretl Team, As a part of my job in function package maintenance, I'm trying to make a Hansl script to (1) create a list of functions available in the Gretl internet server, (2) download them using the new "install" command and, (3) execute the examples. I really appreciate your help to build a list with the names of the functions. I'm using the following code to retrieve the names: <hansl> string functions_page = readfile(" http://ricardo.ecn.wfu.edu/gretl/cgi-bin/gretldata.cgi?opt=SHOW_FUNCS";) string line = "" scalar i = 1 loop while getline(functions_page, line) --quiet string line_name = sprintf("line_%d", i++) string @line_name = strstr(line, "current_fnfiles/") string @line_name = strstr(@line_name, "<tt>") string @line_name = strsub(@line_name, "</td><td>", " ") string @line_name = strsub(@line_name, "</a>", "") string @line_name = strsub(@line_name, "</td></tr>", "") string @line_name = strsub(@line_name, "<p>", "'") string @line_name = strsub(@line_name, "<tt>", "'") string @line_name = strsub(@line_name, "</tt>", "'") string @line_name = strsub(@line_name, "</p>", "'") string @line_name = strstrip(@line_name) if @line_name = "" delete @line_name else print @line_name endif endloop </hansl> It gives me something like this: (...) 'addlist.gfn' 'Allin Cottrell' '1.2' '2010-12-17' 'Sequential addition of variables to a model' (...) Now I need to use just the first piece of the string ("addlist") to combine it with the install command. Something like this: <hansl> install addlist.gfn </hansl> Now my question: How could I extract the first "element" of my string? Best regards / Um abraço, Henrique Andrade
