    Think about it, its an extra 3 bytes per tab... It all adds up. Not to mention it makes the highlighted source easier to "cut & paste" while keeping its original formatting.

    Anywho just thought i'd comment.
    Actually right now codeform prints all whitespace verbatim into the output file. Any tabs, spaces, or newlines in your source file will also be in the output file.

    The HTML output format does indeed use <pre></pre> tags. (See the files rules/_html.)

    If you wanted to have tabs converted to spaces or vice versa you could either do it yourself with a separate program -- it's quite easy; I think I have at least five programs that do it -- or create rules that look like this:
    Code:
    =keyword
    <tab>::<space><space><space><space>:# converts tabs to spaces
    <space><space><space><space>:<tab>:# converts spaces to tabs
    Note that I don't know if that will work; keywords containing spaces might not match properly. (And codeform isn't on this computer so I can't test it.) It should however and if it doesn't just give me a shout.

    Comments are much appreciated.

    You should make a CGI version to perhaps?

    Guess what? I was doing just that. If you'd signed up before the board crashed, I could link you to the thread, but alas it is gone. I wrote a Perl script which ran codeform on the remote server. It worked perfectly, but codeform was running as a priviledged user, opening up tons of security holes. Unfortunately there doesn't seem to be a user called nobody on that server. So I guess I could host codeform version 1.2.0 online, as it is called, but would it be a good idea? . . . .

    My only idea was to restrict the input file to, say, 32KB, to reduce the risk of buffer overruns. Codeform, as I mentioned, does not have any memory leaks when run through Valgrind, but it does have lots of "Invalid read"s. I don't know what those are but I'm guessing they're related to buffer overruns. Once I fix those I think I will host codeform online. We'll see.

    If you have a server that will run Perl scripts that can execute other programs which may or may not have buffer overruns, let me know.

    I did sign-up before the board crashed I lost my account...

    Anywho, as you mentioned in the other thread perhaps link to standard-c functions ?

    And maybe something for the future: use anchors for user declared functions so you can 'skip' to their declarations, eg

    Code:
    <pre>
    
    void Foo(void);
    
    int main(void)
    {
    	<a href="#foo">Foo</a>();
    	return 0;
    }
    
    <a name="foo"></a>
    void Foo(void)
    {
    	return;
    }
    
    </pre>
    Sorry, I don't currently have access to a server , specially not one with, DuN-DUN-DUN PERL!:P

    That's too bad. All I lost was 300 posts. You lost your join date etc . . .

    Actually I just did that really quickly . . . here's the gist of it.
    Code:
    linkfuncbb=[url=
    linkfuncba=]
    linkfunca=[/url]
    linkfuncurl=http://www.opengroup.org/pubs/online/7908799/xsh/
    
    =keyword
    atoi:$(linkfuncbb)$(linkfuncurl)atoi$(linkfuncba):$(linkfunca)
    printf:$(linkfuncbb)$(linkfuncurl)printf$(linkfuncba):$(linkfunca)
    (Highlighted with codeform. ) I still need to find a list of C functions, though. (Feel free to find one. :P) It's used like so:
    Code:
    $ codeform -f rules/c_1_vbb -f rules/clinkfunc
    And maybe something for the future: use anchors for user declared functions so you can 'skip' to their declarations, eg
    Code:
    <pre>
    
    void Foo(void);
    
    int main(void)
    {
    	<a href="#foo">Foo</a>();
    	return 0;
    }
    
    <a name="foo"></a>
    void Foo(void)
    {
    	return;
    }
    
    </pre>
    Unfortunately codeform is currently a single-pass parser. Doing something like that would be impossible. I plan to change it however.

    Sorry, I don't currently have access to a server , specially not one with, DuN-DUN-DUN PERL!:P
    I can find tons of free web hosts that support Perl, but none of them like me executing codeform from within the Perl script . . . not surprisingly.

    I created a IRC bot a while ago, in the process I made a list of most of the standard C functions....

    See the attachment, I know it doesn't contain URLS, but its a start - and it does explain what each does. Perhaps you could add tooltips for the standard funcs instead (so it doesn't rely on the internet)

    Thanks for the list. I'll transform it into some codeform files as soon as I can (probably by tomorrow night). One to turn "printf" into
    Code:
    $(clinkfuncbb)$(clinkfuncurl)printf$(clinkfuncba)printf$(clinkfunca)
    or
    Code:
    [url=http://www.opengroup.org/pubs/online/7908799/xsh/printf]printf[/url]
    and one for
    Code:
    <a alt="printf(f, ...) is equivalent to fprintf(stdout, f, ...)">printf</a>
    perhaps with a link too. I may re-create the alts though. That printf one isn't too helpful.

    Sorry, I haven't finished the clinkfunc rules (as they are to be called) yet. My estimates are always off . . . six months before I first released codeform I said "codeform should be finished within two weeks or maybe three."

    I have implemented doubling-the-allocated-memory-size. It hasn't been uploaded yet though. (It's a simple two line change to get_string().)

    I have attached the latest version of codeform online's Perl script in case anyone's interested. [edit] I attached the wrong file. I'm also attaching the Perl script now. [/edit]

    how about linking standard (or common lib) functions to online definitions (like online man pages or something).

    note. i did put math.h functions names in winapi list. they are included just the names.

    note 2. if anyone wants dx9 list. i may start on it sometime.

    That's exactly what this clinkfunc will do. In theory. Here's an example of what it should look like: counting problem

    Okay, good to know.

    I've decided to risk it and host codeform version 1.2.0 online. Perhaps it should have a new thread -- but too late now.

    Codeform version 1.2.0 online: http://dwks.theprogrammingsite.com/m...e/cfonline.htm

    Tell me how you like it. If you find any bugs please let me know. Just as before, input files are limited to 32KB in size. The Windows API rules are also supported (only for style 1).

    I may not keep codeform online up and running forever, but if I stop hosting it I'll let everyone know here.

    [edit] The Perl script is attached, with .txt added. [/edit]

    > If you find any bugs please let me know.
    The browser will parse #include <header> as #include, and template stuff will also act up,
    which is wrong. At least let your users knw this is the case to avoid a surprise.

    Other than that, you've done a nifty job so far.

    What do you mean?
    Code:
    #include <stdio.h>
    
    template <typename t>
    It works pretty well for me. Post the code you messed it up with. [edit] That's how it's supposed to look BTW. If you were thinking it should look like
    Code:
    #include <stdio.h>
    well, that wasn't how it was designed. twomers wanted the same thing however. It's relatively easy to implement; just get rid of the "#" comment and add these keywords:
    Code:
    =keyword
    #include:[color=green]:[/color]
    #define:...etc...
    I may add an option in codeform online to do that. [/edit]

    Other than that, you've done a nifty job so far.
    Thank you.
