Thanks Adrian!<div><br></div><div>By the way, I found this website yesterday: <a href="http://www.mail-archive.com/ragel-users@complang.org/index.html">http://www.mail-archive.com/ragel-users@complang.org/index.html</a> - I found it very useful for searching ragel's mailing list for help.. the default mailman archive on your site is awful for searching for stuff and following a conversation.</div>
<div><br>Maybe you could consider posting this link on your website, or even better, migrate the mailing-list and it's archive to google groups... Let me know if find this idea useful or if you need any help on that.</div>

This parsing problem requires delaying the action on the first '*' since you don't know if it is a containing '*', or the first character in the terminating string.<div class="im">

Well, I solved this problem by using something like this:<br>
<br>
action mark { text_start = fpc; }<br>
action show { printf("'%.*s'\n", fpc - text_start - 1, text_start); }<br>
<br>
main := '/*' >mark any* :>> '*/' @show;<br>
<br>
I don't know if this is the "correct way" to solve this, but it worked. ;-)<br>
<br>
<br>
Thanks<br>

Hi, I've read the ragel manual a couple of times and searched the<br>
mailing list and I couldn't find the solution to this problem. I<br>
imagine the solution is there somewhere, but I couldn't find it<br>
since I couldn't search the mailing list archive properly.<br>
<br>
BTW, I don't really need to parse c comments, but I found this<br>
example to match perfectly what I am trying to accomplish. I'm<br>
really trying to parse and print data separated by a multi-character<br>
token.<br>
<br>
Page 29 of Ragel 6.7 manual shows an example on how to properly<br>
parse C language comments, but the action @comm also parses the *<br>
caracter at the ending "*/" as shown in the Graphviz image.<br>
<br>
I tried many ways to solve this problem, but I couldn't do it. Can<br>
someone help?<br>
<br>
action comm { printf("%c", fc); }<br>
p = "/* foo *** bar */";<br>
<br>
I tried:<br>
<br>
main := '/*' (any* -- '/*')@comm '*/';<br>
main := '/*' any*@comm :>> '*/';<br>
main := '/*' ( ( any @comm )* - ( any* '*/' any* ) ) '*/';<br>
<br>
But it always prints: "foo *** bar *" (note the * at the end) and I<br>
looking for a way for it to print just " foo *** bar ".<br>
<br>
Is there an easy way to fix this?<br>
<br>
<br>
Thanks in advance!<br>
<br>
