One of the needs I've run across is to enable the program user (possibly a non-programmer) to do logical searches on data.
It would be nice if the search patterns specified by the program user could be used directly by the functions. Search functions of this type would take patterns that are more like what you would use for google or yahoo searches instead of the more complex language re requires.
I'm not sure if I understand this correctly. Perhaps you could give an example or two?
Also, please don't overload my simple little proposal with a multitude of new functionality. My proposal is only meant to be a lightweight convenience function. Additional functionality probably belongs as a different function, maybe even a different module.
Yes, it would be a different module and not added directly to the re module. While you are thinking of simplifying re for programmers, I'm thinking of simplified searches for users. A different target and purpose.
I think your functions would make this idea easier to do.
It would be nice if we could do simple logical searches where.
[word1 word2] ;get results with either word1 or word2 [+word1 +word2] ;get results with both word1 and word2 [word1 -word2] ;get results with word1 and not with word2 ["word one" "word two"] ;use quotes to search for phrases
And possibly use '*' and '?' as simple wild cards but keep it easy to use and simple. More complex searches should use the re module directly.
This would act as a filter for lists and would be suitable for adding a *simple* user search capability to many scrips and applications.
An example would be to enhance pydocs search of the summery lines. Currently if you type "modules key", if the key is multiple words, it only searches on the first word. You can not do searches on multiple words or exclude results with certain words.
While we could allow regular expression input to work, for many applications it is overkill and it is too complex for many users. For example I would not like to try and teach my parents all the subtleties of regular expressions when they are struggling to understand a lot more basic things. They don't want to learn how to program computers, they just want to get a recipe that has [+chicken +"tomato sauce" -onions].
