<div dir="ltr"><div class="gmail_default" style="font-size:small">FWIW, an "rg_" prefix isn't making anything less confusing. I'd prefer actual variable names that indicate what each is for, as one might use if writing the code by hand (math people excluded!).

So people can have time to migrate their ragel code. This kind of things has been done all the time. I don’t think it should be an excuse not make the variable name more readable. “access” can solve the readability problem, but it also uses an extra structure which changes the meaning of the code. I will check “variable” later.</div><div dir="auto"><br></div><div dir="auto">BTW, how many uses of ragel anyway? It seems to have a far less user base than flex. My impression is that people uses it because it can offer something flex does not offer. However, flex can already solve a lot of lexing problems. So there will be much less users use ragel than flex. This can be shown by the numbers of questions on stack overflow and the numbers of projects on github.</div><br><div class="gmail_quote"><div>On Sat, Feb 23, 2019 at 3:52 AM Adrian Thurston <<a href="mailto:thurston@colm.net" target="_blank">thurston@colm.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">You can use the variable and access statements (section 5 of the <br>

Changing the default behaviour at this point would break every ragel <br>
program out there and that's not something I'm interested in doing.<br>
