I'm converting my "working documents" for Synchronet (to-do list, FAQs, etc) to HTML and needed an easy way to "share" these files with the users on the BBS, without requiring them to download them and view them in a web browser.

So, I spent "some time" today creating this little "diddy" in Baja and just thought I'd post the source here since it's probably the most intense Baja coding I've done since QNET.SRC (QWK networking module for SBBS v2). I'll be putting this on Vertrauen for download too.

It only handles BASIC HTML right now, so don't be too shocked if it doesn't print your more elaborate HTML files very nicely. Obviously, things like graphics and fonts can't be well represented on a typical telnet terminal. (HTML to RIP anyone?)

Well, here it is:

So, I spent "some time" today creating this little "diddy" in Baja and just thought I'd post the source here since it's probably the most intense Baja coding I've done since QNET.SRC (QWK networking module for SBBS v2). I'll be putting this on Vertrauen for download too.

Any reason why I can't FTP this file?

I can't seem to get Z-Modem working on this box, and when I tried to connect to the FTP server it kept refusing to allow me online. I get "530 not logged in" as soon as I put in the password.

I don't know. Other people (and myself) have been able to login just fine. Is it possible you forgot the "user" command?

I don't know what to make of it. The PW is not shown because it doesn't

Okay! I can get onto vert.synchro.net but not ftp.synchro.net for some reason. Let me try something else:

Hehehe! :) <-- red face! Okay, so if I use anonymous FTP then I get on
to ftp.synchro.net without problems. Sorry about that - I guess I need more sleep or something...

I had to change line 44 of TYPEHTML.SRC to:

fopen file O_RDONLY|O_DENYNONE filename

to make it compile without an error. Was that a typo on your part, or do I have an outdated version of the BAJA compiler that just wouldn't accept what you had in your source code?

And it corrected the error??? Mow THAT is a feat of debugging skill, the likes of which has not been seen for many a day.....

How long did it take you to figure out the changes?

That's O_RDONLY followed by a pipe and then O_DENYNONE. Apparently the pipe gets itself garbled when posted here? That would explain it.

You probalby have Celerity or Renegade color codes enabled on your system, in which case the "pipe" symbol gets eaten.

I'm seeing a pipe in the original and in both your "corrections". Hmmm I wonder if those pesky colour codes (is it WWIV?) are to blame?

They're Celerity and Renegade color codes, and I have them disabled here on Vertrauen. :-)

I seem to recall doing O_RDONLY+O_DENYNONE instead of O_RDONLY|O_DENYNONE in the past to avoid this problem. It isn't exactly perfect but it _usually_ works, so long as the items you are ORing are single-bit-on values...

Pity you can't do <code><pre>Yada Yada</pre></code> eh? At least, not YET...

:)
