Jakarta Project: String Tag library (Development) Revision History

2002/10/07 - 1.0

Initial release of the String Taglib, to give users a stable released version to work against.

New features added since initial release

• Changed implementation of random() to use the same Randome instance across calls. This stops the same value coming out if called in the same millisecond.
• Swapcase tag. Non-alphabetical text was replaced with the previous alphabetical character and not left alone. this_is_blue becomes thississblue.
• Substring tag. Added protection into substring so that it doesnt complain when end indexes larger than the string are passed in.
• Added ability to pass -ve indexes in, meaning distance from the end of the string.
• Newlines on their own were being rubbed out in the wordWrap method. More generically, any whitespace delimiter was being rubbed out. This is due to the fact that the method considers whitespace to be the type of character to split upon. It forgot that a newline was a whitespace though.
• Changed implementation of StringWisLine so it doesn't try to goto the n+1th element of an array. Was a missing -1 in the algorithm's max value.
• Updated StringW.center/leftPad/rightPad inline with fixes in Commons.
• Updated StringW.replaceString with the version in the Commons.
• Fixed StringW.evaulateSet's javadoc.
• Fixed a logic fault in the negation logic for CharSet class.
• ReverseDelimitedString renamed to ReverseDelimitedStringTag.
• Substring tag default start set to be 0 so an end can be specified on its own. Default end no longer -1 as implementation no longer uses that.
• Fixed a bug in which the tags were returning SKIP_BODY. This is illegal in a doEndTag method. Now it returns EVAL_PAGE.
• Added a 'var' attribute to all tags. The var attribute tells the tag to place the result in the pagecontext under that variable name and not to output the result to the screen.
• Switched String taglib to be dependent on the beta release of Jakarta Commons Lang. This removes a large amount of the utility code from the taglib.
• Added left, right and mid tags to the taglib. These are new methods in the StringUtils class in Commons Lang and it makes sense to offer these up as and when they arrive.
