After some testing I enhanced the code to allow for an empty substChar and a setting, which characters to preserve. The updated docs:
config.simulateStaticDocuments_substChar
- Datatype: string
- Description: The character(s) to use for substitution of non alphanumeric characters. Be carefully with this, to not mess up generated urls, the chars are used unchecked, just as they are. Note, that a string of more than one character is accepted al well and substituted in. Usually you will just want to set it to '-' (a single hyphen), also set the ....substConsecutive to true and the ....substPreserve to empty. You can remove the default char by setting this to an empty value like so:
- Sample: config.simulateStaticDocuments_substChar =
- Default: _ (one underscore)
config.simulateStaticDocuments_substPreserve
- Datatype: string
- Description: Characters to preserve additionally to alphanumeric ones. There ain't too much choices, usually only '_' (underscore) and '-' (hyphen). Important to note: if you want to preserve the '-' (hyphen), then be sure to list it LAST in this string, as it actually is used as the last part of a regular expression pattern. Failure to NOT listing hyphen last might give you strange results. Note also, you can't preserve the substitution character. You may clear the default as described under simulateStaticDocuments_substChar by just setting ...._substPreserve to empty.
- Default: _- (underscore and Hyphen)
config.simulateStaticDocuments_substConsecutive
- Datatype: boolean
- Description: Wether multiple consecutive occurrences of the substitution character/string should be reduced to just one.
- Default: false
The patch (submitted next) is built to change the previous behaviour as little as possible, so if you don't use any of the config.simulateStaticDocuments_subst* settings, your generated URLs will seldom differ from before applying the patch. Only with titles longer than the number of chars given in config.simulateStaticDocuments_addTitle you might see a minor difference.
Also the patch will NEVER influence any link to your site existing around the world negatively (even, if the packets would have to travel 3 times around it :-) ): the generated string is purely cosmetic/aesthetic/human readable/search engine friendly and gets ignored all of the time when the URL is resolved by Typo3.
