texinfo: cannot display the flex documentation

[akimd (Akim Demaille)]

Open the info doc of flex with info, go to the node "Multiple Input Buffer", and see that node ending with:

                 yyin = fopen( yytext, "r" );

                 if ( ! yyin )
                     error( ... );

and all the rest is missing. If you read directly the info file, you will find:

         <incl>[^ \t\n]+   { /* got the include file name */
                 yyin = fopen( yytext, "r" );

                 if ( ! yyin )
                     error( ... );

                        yypush_buffer_state(yy_create_buffer( yyin, YY_BUF_SIZE ));

                 BEGIN(INITIAL);
                 }

and it continues.

Emacs displays properly this documentation.

Marked as nomaintainer@macports, I don't know where I should send this.

I don't know whose bug this is either, but I would be surprised if this were a MacPorts-specific problem. Do you see this problem with any other ports' info files? If so, try asking the developers of info for help. If you just see the problem with flex's info files, try asking the developers of flex for help.

Yesterday I have asked a friend to try on his Linux box, and the documentation was properly displayed (both Flex and Texinfo were provided by his distro). I still have to compare the info files themselves to see what the difference is.

[akimd (Akim Demaille)]

I did the following experiments:

• read my flex.info from MacPorts on a GNU/Linux: it works as expected.
• read the GNU/Linux's flex.info on my MacPorts: it fails. I have changed some words in this flex.info to make sure this is really that one which is read, and it is.
• FWIW, flex.info is stamped by makeinfo 4.8 in the MacPorts, 4.13 on the GNU/Linux, and there seems to be an off-by-one difference, but does not seem have any impact given the previous results.

So really, I'd say this is something wrong in info, not in flex.

[jmroot (Joshua Root)]

Apparently the 4.13 release was slightly botched and 4.13a was released almost immediately afterwards. Does it makes any difference to this bug if the port uses the 4.13a sources?

[jmroot (Joshua Root)]

Is this still a problem with the current version?

[akimd (Akim Demaille)]

Replying to jmroot:

Is this still a problem with the current version?

Nope, it works. Cheers!
