+
+ <h1>Variable Expansion</h1>
+
+ <h2>Abstract</h2>
+
+ OSSP var is a flexible, full-featured and fast variable construct
+ expansion library. It supports a configurable variable construct
+ syntax very similar to the style found in many scripting languages
+ (like <tt>@name</tt>, <tt>${name}</tt>, <tt>$(name)</tt>, etc.)
+ and provides both simple scalar (<tt>${name}</tt>) and array
+ (<tt>${name[index]}</tt>) expansion, plus optionally one or more
+ post-operations on the expanded value (<tt>${name:op:op...}</tt>).
+
+ <p>
+ The supported post-operations are length determination, case conversion,
+ defaults, postive and negative alternatives, sub-strings, regular
+ expression based substitutions, character translations, and padding.
+ Additionally, a meta-construct plus arithmetic expressions for index and
+ range calculations allow (even nested) iterations over array variable
+ expansions (<tt>..[..${name[#+1]}..]..</tt>). The actual variable value
+ lookup is performed through a callback function, so OSSP var can expand
+ arbitrary values.
+
+ <p>
+ <blockquote>
+ <font size=-1>
+ Hint: There is also an ISO C++ derivative of the OSSP var library, named
+ <a href="http://cryp.to/libvarexp/">libvarexp</a>. It is based on
+ a development version of OSSP var and hence does not provide exactly
+ the same amount of functionality. But it provides an ISO C++ API and so
+ can be of interest to you if you are programming in ISO C++ (where OSSP
+ var's ISO C API might be too boring for you).
