An unfortunate consequence of the := operator's behaviour. Also, update copyright years.

haven is an umbrella project for a range of mostly desktop applications.
This README is being converted into a wiki on the wiki branch, also publicly available at https://p.janouch.name/haven/Haven.html. We should only document here that which has been created, as the extent of the rationale and plans is gigantic and seems to have a life of its own.
The greater goal is to create a fresh computing environment for daily work and play--easily controllable, reasonably complex, both visually and internally unified and last but not least responsive. One should be able to use it comfortably with a 60% keyboard and no pointing device.
haven serves as a testing ground, leaning on the side of compromises. It aims to use today’s Linux desktop as a support, relying on X11/Wayland, existing window managers and web browsers.
The focus is therefore on going breadth-first, not depth-first. Applications only need to be good enough to be able to replace their older siblings at all. I.e. for me personally.
Subproject names aim to have the minimum viable, reasonably identifiable name. To group them together, a common prefix of "h" is used. The second column is what should be used as the name in .desktop files, just like the GNOME project figured out it would make sense:
hbe - bitmap editor
hbfe - bitmap font editor
he - text editor
hfm - file manager
hib - IRC bouncer
hic - IRC client
hid - IRC daemon
hiv - image viewer
hm - mail client
hmpc - MPD client
hnc - netcat-alike
ho - all-powerful organizer
hsm - system monitor
hss - spreadsheets
htd - translation dictionary
ht - terminal emulator
htk - GUI toolkit library
See Projects for more information about the individual projects.
Some taken names in Debian: hd (important), hte, hy.
These are sorted in the order in which they should be created in order to gain the best possible momentum. The htk GUI toolkit is implied as a side product permeating the entire list.
Some information is omitted from these descriptions and lies either in my head or in my other notes.
hid -- IRC daemon
This project is unimportant by itself, its sole purpose is to gain experience with Go on something that I have already done and understand well. Nothing beyond achieving feature parity is in the initial scope.
One possibility of complicating would be adding simple WebSocket listeners but that’s already been done for me https://github.com/kiwiirc/webircgateway and it’s even in Go, I just need to set up kiwiirc.
Later, when we have a pleasant IRC client, implement either the P10 or the TS6 server-linking protocol and make atheme work with a generic module. Alternatively add support for plugins. The goal is to allow creating integrated bridges to various public forums.
hnc -- netcat-alike
The result of testing hid with telnet, OpenSSL s_client, OpenBSD nc, GNU nc and Ncat is that neither of them can properly shutdown the connection. We need a good implementation with TLS support.
hpcu -- PRIMARY-CLIPBOARD unifier
An improved replacement for autocutsel in selection synchronization "mode":
using only one OS process;
not polling selections twice a second unnecessarily;
calling SetSelectionOwner on change even when it already owns the selection, so that XFIXES SelectionNotify events are delivered;
not using cut buffers for anything.
Only UTF8_STRING-convertible selections are synchronized.
hswg -- static website generator
ht -- terminal emulator
Similar scope to st(1). Clever display of internal padding for better looks.
hib and hic -- IRC bouncer and client
An IRC client is a good starting application for building a GUI toolkit, as the UI can afford to be truly minimalistic and most of it is text.
To resolve an issue I have with my current IRC client, the client is going to be split into two parts: a bouncer that manages all connections and state, and a separate GUI that communicates with the backend over TLS/WebSocket. Perhaps only the per-buffer input line is going to be desynchronized.
The higher-level client-server API could be made rather generic to allow for smooth integration with non-IRC "backends" such as Slack or Mattermost.
he -- text editor
VIM controls, no scripting, no syntax highlight, single-file, made for variable-width/proportional fonts. Initially done primarily to produce a text editing widget, which is going to be an interesting challenge, arguably better solved by whole program composition. Scintilla may provide some inspiration.
In the second stage, support for the Language Server Protocol will be added so that the project can be edited using its own tools. Some scripting, perhaps a tiny subset of VimL, might be desirable. Or other means of configuration.
Visual block mode or the color column may still be implemented.
The real model for the editor is Qt Creator with FakeVIM, though this is not to be a clone of it, e.g. the various "Output" lists could be just special buffers, which may be have names starting on "// ".
ho -- all-powerful organizer
Zettelkasten with fulltext search, arbitrary reciprocal links, arbitrary tags. Flat storage. Should be able to use translation dictionaries for search hints.
Indexing and search may be based on a common database, no need to get all fancy:
htd -- translation dictionary
This specific kind of application doesn’t need a lot of user interface either, just a tab bar, text entry and two columns of text with simple formatting.
For simplicity we will establish a custom dictionary format based on either simple compress/gzip with separate files in StarDict style or, since we don’t really strive for random access and memory-efficiency (those 120M that sdtui takes with my 10 dictionaries isn’t particularly bad), pack everything with archive/zip.
Instead of ICU we may use x/text/collate and that’s about everything we need. Since we have our own format, we may expect the index to be ordered by the locale’s rules, assuming they don’t change between versions.
hmpc -- MPD client
Here the focus will be on the GUI toolkit. I don’t expect this application to get big, since its predecessor nncmpp isn’t either. The daemon takes care of all complex stuff. It would be nice to add lyrics and search later, though.
hiv -- image viewer
JPG, PNG, first frame of GIF. Zoom. Going through adjacent files in directory using cursor keys. Possibly a dialog with image metadata.
hfm -- file manager
All we need to achieve here is replace Midnight Commander, which besides the most basic features includes a VFS for archives. The editing widget in read-only mode could be used for F3. The shell is going to work very simply, creating a PTY device and running things under TERM=dumb while decoding SGR, or one could decide to run a new terminal emulator with a different shortcut. ht could probably also be integrated.
Eventually the number of panels should be arbitrary with proper shortcuts for working with them. We might also integrate a special view for picture previews, which might or might not deserve its own program.
hss -- spreadsheets
The first version doesn’t need to be able to reference other cells, and can more or less be a CSV editor.
We can take inspiration from Excel:
Currently there are no significant, specific plans about the other applications.
