Resolves#4411:

By joining the url and title with a space, we ensure that the last word
of the url and the first word of the title are treated as separate
words.
This is a more "Qt" way of highlighting syntax, and works around the
problems of #4199 without resorting to complicated html escaping.
The tests are more straightforward with less mocking, but do involve
testing a private class.
Resolves#4199.
To avoid accidentally highlighting characters that were introduced by
html escaping the text before feeding it to setHtml, we can't just
escape the whole string before adding the highlighting. Instead, we need
to break the string up on the pattern, format and escape the individual
parts, then join them back together.
re.escape includes empty strings if there is a match at the start/end,
which ensures that matches always land on odd indices:
https://docs.python.org/3/library/re.html#re.split
> If there are capturing groups in the separator and it matches at the
> start of the string, the result will start with an empty string. The
> same holds for the end of the string
Resolves the example case in #4199, but not the larger problem. We don't
need to escape quotes as we don't put the string in an attribute value.
From the docs at
https://docs.python.org/3/library/html.html#html.escape:
> If the optional flag quote is true, the characters (") and (') are also
> translated; this helps for inclusion in an HTML attribute value
> delimited by quotes, as in <a href="...">.
Escaping quotes means we end up with a literal ' in the completion
view wherever there is a quote in the source text.
However, problem in #4199, where unexpected parts of the text are
highlighted, can also happen with '<', '>', and '&', which still must be
escaped.
There were no unit tests for this whole module. It is difficult to test
due to all the private logic and Qt dependencies, but with a lot of
mocking we can at least validate some of the text handling.
This is a setup to start testing the solution to #4199.
I picked '{' and '}' as placeholders in the test data because they draw
the eye to the 'highlighted' part, and vim even highlights them with
python syntax highlighting. It could be confusing though, as they look
like format strings but are not used that way.
If the blacklist is only valid for the completion, the setting should also be
under completion.
This also un-renames history.gap_interval and renames
completion.web_history_max_items.
`ListCategory` sorts its completion by default, we are already building
the categories in the right order so don't need that.
The test tests the case of where you have 11 tabs and if the model was
sorted the tabs with index 10 and 11 would be sorted before the one with
index 2.
The `random.sample` bit for the tab url and title is to also make sure
the model isn't being sorted on those columns, whithout haveng to write
and all ten lines.
Allow completion functions to react dynamically to args as the user
inputs them. This allows config-cycle to filter out values that were
already provided.
Args provided after the maxsplit do not cause the completion to regen.
For example, successive words typed after `:open` just set the filter
pattern and do not spuriously regenerate the completion model.
When a command has positional varargs, keep offering the configured
completion for each successive argument.
Right now this only influences `config-cycle`.
Previously, `config-cycle <option> ` would offer a value completion for
only the first argument after the option. Now it will keep offering
value completion for each successive argument.
This will be useful for passing multiple tags to the new bookmark
commands that will be added for #882.
When min_chars is nonzero, if the first command that opens the
completion has < min_chars on the word under the cursor, it triggers a
check for a condition where last_cursor_pos is None.
By setting last_cursor_pos=-1 we ensure that the completer always
updates the first time it is opened, and that there is never a check
against None.
This adds a test for the min_chars feature.
Resolves#3635.
Always interpret the first word in the command string as the command to
offer completions for, even if that word looks like a flag.
Fixes#3460, where the command string `:-w open` would attempt to offer
completions for `open` but crash because the parsing was thrown off.
By moving the flag-stripping logic to _after_ we determine the command,
`:-w open` interprets `:-w` as the command. Since that is not a valid
command, we won't offer any completions.
I mistakenly checked the length of wheres instead of words. This fixes
that check, renames 'wheres' to 'where_clause' to be clear
that it is a string and not an array, and adds a test.
Perviously, 'foo bar' would match 'foo/bar' but not 'bar/foo'. Now it
will match both, using a query with a WHERE clause like:
WHERE ((url || title) like '%foo%' AND (url || title) like '%bar%')
This does not seem to change the performance benchmark. However, it does
create a new query for every character added rather than re-running the
same query with different parameters. We could re-use queries if we
maintained a list like self._queries=[1_arg_query, 2_arg_query, ...].
However, it isn't clear that such a complexity would be necessary.
Resolves#1651.
