Add shortcuts to make entering queries more efficient
CTRL+F: Highlights rightmost filter, e. g. c:(word1 word2) would
highlight everything between (), so "word1 word" here. Alternatively,
highlights lone words, so p:(docs) word1, would highlight word1.
CTRL+W: Removes last filter or words.
Since 7c5c91e we wrongly merge lone words for paths queries too.
This creates unintended behaviour.
Fix it by creating a new paths query without merged words, which
restores the original behaviour.
Also, get rid of some redundant calls to createFinalTokens()
Avoid double results in search by distinguishing whether
a filter was explicitly given. Previously, we could not
discern this.
Furthermore, if a content search is given, lone words will be
considered path searches. If a path search is given, we consider
lone words implicit content search filters. This simplifies
queries for the user
Sigh. quazip changed the lib name, include locations, etc. from version 1.
Some distributions only have 0.9. Some only 1.x and so some packages break,
so they simply patch it when building the package.
Luckily, nothing we use from quazip is affected from an API perspective.
So detect if there is quazip1, then use pkg-config to link that, else do it like before.
Not entirely ideal, since we may want to search for 'cake', and look at
a preview for 'cake.txt' even if there is no 'cake' inside.
But this will do for now
Switch to QCoreApplication, since the ipc worker is not a GUI application.
We can also remove some vows this ways. Furthermore, disable connect() syscall
explicitly.
While f67a37bc21 indicated the last remaining code could stay,
it can't because there is a launch failure of SandboxedProcessor.
This has been revealed by the changes of the previous commit,
aa03d0a4920e.
Hence, the GUI will be untouched by exile. We only sandbox
the preview generation and the indexing trough IPC.
There was an off-by-one, the SandboxedProcessor was only passed
'process', not the path to the file.
No processor was found for 'process', thus 'nothingProcessor' was
returned. Therefore, we never sandboxed (because we never had
to process anything).
The sandboxing would have failed though, because we need to launch
QCoreApplication, not QApplication.
The CLI was never affected.
It was possible the text was getting too big. The GUI
was lagging for previews of some text files. The first
assumption was that we would only have a couple of hits,
which is unreasonable for large .txt files and common
words.
We only ever see a handful of previews, it makes no sense
to get all snippets. So just allow 7 snippets, that's it.
Also, just cut after 1000 chars no matter what.
