People who have visited any of the larger C++ conferences surely know Rainer Grimm, know his talks, workshops and books.

Unfortunately, he has been diagnosed with ALS, a serious progressive nerve condition.

Since ALS research doesn’t get much attention or funding, Rainer started a fund raising campaign for funding ALS research with ALS-Ambulanz of the Charité and I Am ALS organization.

The recording of my keynote at this year’s Meeting C++ in Berlin has been published on Meeting C++ channel on YouTube:

The talk is about prog (or progressive) C++ and idioms that make C++ code provably safe.

The slides are available in the Traning and talks section.

Huge thanks to Jens for tirelessly organizing Meeting C++ for this many years (this was my tenth year presenting at Meeting C++, and I skipped a few).

Some time ago, I wrote a post about integrating Qt’s associative containers with the fancy new C++ features, range-based for loops with structured bindings.

That post inspired KDAB’s own Giuseppe D’Angelo to add the asKeyValueRange member function to both QHash and QMap. Now it’s possible to iterate over them with a simple range-based for loop, like so:

for (auto [key, value] : map.asKeyValueRange()) {
    // ...
}

The second part of my previous post demonstrates how we can iterate over Qt SQL results using a range-based for loop as if it were an ordinary collection.

This post covers what is needed to be able to traverse the SQL results in a much nicer and safer way like so:

for (auto [active, name, team] : QSqlResultTypedRange<bool, QString, QString>(query)) {
    qDebug() << "active(bool):" << active;
    qDebug() << "name(QString):" << name;
    qDebug() << "team(QString):" << team;
}

I’ve been revamping my Neovim configuration (more on that some other time).

I used to have a fuzzy searcher of Qt and C++ docs in Vim which would open the thing I searched for in a web browser or Qt Assistant (or cppman, but that is cppref only).

That was tedious for a several reasons I’m not going to go into now, so I decided to use this Neovim configuration revamp to make shell-based documentation nicer.

Enter zeal-cli

Zeal is a really nice offline documentation browser that comes with more than 200 documentation sets. And you can also create your own sets. (for Qt users, imagine Qt Assistant, but with docs about everything)

Now, Zeal doesn’t have a nice CLI API, but the docset format is simple enough for it to be used even without the Zeal application (after you use it to download docsets you want).

And that is exactly what zeal-cli does.

It is a small python script that shows Zeal docs in the Lynx console web browser. It can also clean-up the html pages from noise like navigation menus, table of contents and other things that just take valuable space before showing them in Lynx.

Usage is quite simple – you specify the docset you want to use and which page to show:

zeal-cli cpp std::string

Fuzzy searching

zeal-cli can also list all the pages available in a docset which can be used along with an application like FZF for fuzzy searching the documentation. You can just pipe the output of zeal-cli to fzf to get a similar view to the screenshot above:

zeal-cli cpp | fzf --height=50% --preview='zeal-cli --lynx-dump=true cpp {}'

Neovim integration

I’ve also made a small Fennel-based plugin for Neovim and Telescope.nvim to be able to search and show the docs inside of Neovim. This plugin in action is what the screenshot above shows.

There’s room for improvement for both zeal-cli and nvim-telescope-zeal-cli and patches are welcome.

I promised gocryptfs support in Vault a long time ago, but I kept failing to deliver on that promise because of other obligations, life and work happenings.

Now, the beauty of Free Software is that the users do not need to rely only on my free time for new Vault features.

Martino Pilia sat down and wrote a gocryptfs backend for Plasma Vault which has been merged and will be available in Plasma 5.19. Many thanks for that!

As with all new things, you are advised to be cautious as there might be some bugs remaining we haven’t detected.
