String Literals - SuperQuotes

[Charles Pegge]

Oxygen supports multi-line strings using ` (and also " outside of a thinBasic script. )

Below is a new kind of string literal suitable for embedding guest scripts that use quote marks themselves.

( With inline thinBasic scripts however, you can't use single or double quotes)

The format for a superquote is:

quote any_marker_word ... any_marker_word

This can be spread onto more than one line:

quote
any_marker_word
...
any_marker_word

Charles,

In ScriptBasic the """ is used for multi-line strings and remarks.



PRINT """
<a href="some.url">Example</a>
More text with a """ & myvar & """\" showing a quoted "
string right after the variable.
"""
' """Here is a multi-line
comment"""

Hi John,

Yes I saw that. Nestable quote marks are very useful.

Superquote is really the nuclear option, since any marker keyword can be used, supporting unlimited quote nesting.

& Oxygen can have up to 3 types of conventional quote available to the programmer - all of them multi-line.
These can be reprogrammed at any time within a program.

Like to keep the options open :)

Oh, this means you tried ScriptBasic.

Thanks for having a peek.

Not only nestable but the original format of the text (indents, tabs, line terminators) is maintained between the triple quote delimiters. Great for encapsulating blocks of verbatim HTML text your pushing out to the browser. 8)

Well I'm getting close John. I've installed Script Basic and I'm dipping into the manual and documentation from time to time, and thinking about the best way to proceed for a Linux/MS implementation.

BTW You mentioned developing a COM module for scriptBasic - this is one of my current lines of research. COM, particularly on the server side, is a tangle of pointers and I need to establish at this stage how well Oxygen can cope with it avoiding the dogs breakfast of workarounds I had to go through three years ago. I want to ensure that the language supports it cleanly. Let's see if Oxygen can make COM servers intelligible.

That's great news !

It might be worth having a look at the BCX Basic to C COM/OLE Automation code written in ANSI C. It might save some time and grief.

Let me know if there is anything I can do from my end to make your experience with SciptBasic a success.
