"Search by text" (aka regex search)

[jeremybmerrill]

supersedes #873 by @slmendez et al.

@jazzido, @mtigas would love your eyes on this one. I propose that we aim to do a Beta/Preview release, so some users can take it for a spin and give us feedback. Then see where we're at.

I've done some substantial cleanup, moving raw CSS into SCSS, rewriting some event handlers, putting templates in the right kinds of places, putting the Search by Text toolbar behind a button. I also wrote through all the copy.

The Regex Search I've renamed Search by text so non-regex aware users can use it (but the guts are the same, it still supports regex). One question I'm still pondering is whether the searches created by the regex search should be individually deleteable/movable/editable.

One big win from this is testing: mvn test tests the UI, which is a thing we've needed for a few years.

Thanks for taking care of this, @jeremybmerrill — I'll try to find some time this weekend to review.

BTW, I went ahead and deleted some files from the root directory (old versions of the PDFBox jar (!), an IDEA .iml file, et cetera)

[jazzido]

BTW, we should do a merge from master onto this PR. The branch point for this feature is ages old.

[jeremybmerrill]

Thanks. I'll check out merging master back in when I get a chance. (It can't be that old, can it? It's not like there've been many commits in the past year.)

True. I mentioned that anyway because of the list of conflicted files that Github shows:

@jazzido : I think I fixed the conflicts. I'm not sure exactly where you were looking, but can you check again?

I'm not sure why only one of the Travis checks passed, but the other failed. Might just be a sporadic erro (the thing that failed is just checking for a button's presence... and that button is there (and it works on my computer).)

Does this branch/PR make it possible to select/position tables relative to the xy coordinates of search text in a PDF document? I recently opened a feature request issue for this feature:
https://github.com/tabulapdf/tabula/issues/1101
... and then I found this PR.
If so, is there a working build of this that we might use? We don't necessarily need to use the GUI if that is holding up merge/use of this functionality - we could use a command-line based version and would love to have one if it exists.
If not, are there other approaches to doing this within Tabula, or other tools that can do this?
Thank you for your help.
