Moving Up From Web Design

Sometimes you will see people posting something like, "I've been creating web sites for years using HTML and FrontPage but I'd like to know how I can take the next step. How do I become a web developer?" Usually the answer provided is something like, "You should learn PHP."

Is PHP the answer? The answer is of course, it depends.

If you're just looking for a job skill you can put on your resume, then PHP may be exactly what the doctor ordered. But, if you are building your own sites or are doing custom work for a client, or want build something for use at the office, or if you just want to learn because programming interests you then you really should consider Run BASIC. You can get something going faster with Run BASIC than with more traditional web tools because Run BASIC is designed to be easy. It doesn't try to fit into the mainstream notion of a web tool. There are just too many of those.

Take a look at the site at http://www.runbasic.com/ for more information.

Database and web capabilities

Our Run BASIC + SQLite integration is coming along nicely, and it lays the groundwork for using other databases later on (Oracle, SQL Server, MySql, etc.). One thing that we did to make using databases handy is that we built in some display technologies. You can query the database and then just use the RENDER statement to put the result on the web page. You can also inject some CSS styling right into that result, and you can even turn the line items of any column in the displayed table into links.

We also have added an httpget$() function so you can use HTTP to retrieve web documents like web pages, RSS feeds, etc. We plan to include an XML parser, and if we can come up with an easy to use way to stream through an HTML document we will provide that also.

These capabilities (except for the table rendering) will also be included in Liberty BASIC v5.0.

BASIC and CSS

One of the important aspects of integrating a programming language with web development is page layout. Until recently this would have meant inserting lots of HTML tags into your source code. You can do this with Run BASIC.

However there is a better way. It is called CSS (Cascading Style Sheets). This provides a way to wrap the things on your web page with tags that you give your own names to, and you defined the appearance of the stuff wrapped in those tags somewhere else. This way your program's code has very little extra stuff in it to clutter up your code. If there is too much clutter it can be very hard to understand what code means, and this can slow you down and lead to bugs.

So, Scott McLaughlin and I have begun to integrate CSS with Run BASIC. We added a CSSID statement (originally this blog entry had this as CSS, but we changed the command), a DIV statement, and an END DIV statement. Here's a very short example:

cssid #myTag, "{ background: #FFDDDD; font-family: tahoma }"

div myTag
print "count to ten"
for x = 1 to 10
print x
next x
end div

Okay, so this displays all the text printed between the DIV and the END DIV with a light red background, and using the tahoma font. The #myFont token isn't a handle like the ones used for files and GUI controls. The # is simply part of CSS syntax.

DIV statements can be nested, and the contents of one DIV block will be rendered on the page nested inside of each other.

There is a lot more that can be done with CSS, and we're trying to explore what are the simplest and most useful things to include in Run BASIC.

We will be posting a screencast in the next few days that shows how this works.
