Probably. However the name has been chosen to honor one of the greatest visionaries of computer supported collaborative writing, Douglas Adams, author of "The Hitchhiker's Guide to the Galaxy", one of the funniest and greatest books on earth. In his books he envisioned a travel guide for aliens, which was updated by multiple editors collaborating over the "SubEthaNet". SubEthaEdit is pronounced Sub-Etha-Edit. Sub like in "Subway", Etha like in "Ether", and Edit like in "Editor". In a previous life, before a trademark dispute, SubEthaEdit was called "Hydra".
Due to the rules of the Mac App Store, SubEthaEdit's command-line tool must be downloaded separately by clicking this link and double-clicking the resulting file.
Like the command-line tool, we have to ship this extension seperately. Please download this package, uncompress it and place the scpt file in your ~/Library/Application Scripts/de.codingmonkeys.SubEthaEdit.Mac folder. If you try to edit a file which requires the extension, SubEthaEdit will automatically open the Folder.
We will be collecting new and old modes at Github. Old modes might need to be slightly updated for SubEthaEdit 4.
Have a look at "Help → Regular Expressions" for a summary of SubEthaEdit's regular expression vocabulary. To learn about basic and advanced regular expressions we recommend http://www.regular-expressions.info.
