SBASICW
sbasicw
is a web server which can display the output of a SmallBASIC program in a browser. It can also be used to dynamically generate websites using SmallBASIC commands.
Getting started
Render to canvas
Launch sbasicw
(Linux) or sbasicw.exe
(Windows) in a folder containing the files of your website. It is quite
helpful, if sbasicw
is in the search path. After you
started the web server you can open in your browser the URL
http://127.0.0.1:8080
. This will display the file
index.html
. You can also load
http://127.0.0.1:8080/myprogram.bas
. This will execute the
SmallBASIC file myprogram.bas
. The output (graphics and
text) will be rendered to an HTML5 canvas and displayed as a bitmap in
your browser. Only a snapshot of the output is displayed i.e., you would
only see one frame of an animation in your web browser.
HTML text output
Launch the web server in a folder containing the files of your website with the following command:
sbasicw --graphic-text="0"
If you call a SmallBASIC file, graphics output will still be rendered
to an HTML5 canvas. But output of the print
command is
interpreted as text by the browser. You can print HTML and even Java
script commands.
Transfer data
sbasicw
supports sending data using the get method. To
send variables to a SmallBASIC program add
?var1=value1&var2=value2...&varN=valueN
to the URL
of the website. You can then read the values of the variables using the
env()
function, for example
v = env("var1")
.
Tutorial
sbasicw_tutorial.zip contains several HTML and SmallBASIC files. To start the tutorial extract the files to a folder of your choice and launch the web sever in this folder with:
Linux: sbasicw --graphic-text="0"
Windows: sbasicw.exe --graphic-text="0"
Open a browser and start the tutorial with
http://127.0.0.1:8080
. You will learn how to link between
HTML files, dynamically generate HTML files using SmallBASIC, create
forms, process the input of the forms and draw graphics to an HTML
canvas.

Run the web server in the background
If you want to start the web server in the background, use the following command:
sbasicw &
sbasicw --graphic-text="0" &
If an error message like
[1] + suspended (tty input) sbasicw
is displayed, then
start the server with:
sbasicw < /dev/null &
sbasicw --graphic-text="0" < /dev/null &
