DlangUI 0.9.0: Console backend added
Hello! Now it's possible to build DlangUI apps to run in console (Linux, Windows). When DlangUI is built with version=USE_CONSOLE (dub subconfiguration "console" for dlangui library) - it works in terminal. Such feature may be useful, e.g. to run apps on headless devices, or via SSH. For simple apps, it's enough just to specify dlangui configuration console. No additional changes required. If custom themes are used, additional theme files prefixed with "console_" are to be created. If custom embedded resources are used, create additional resource list file, with "console_" prefix. Margins, padding, size values if specified in pixels are to be changed. Hint: use points or EMs for such values to get them working universally on both console and GUI. If images/icons are used, and still needed in console mode, you may need to create ASCII art like text image files (.tim extension). Some screenshots (from dlangui example1 app): http://i63.tinypic.com/2wn1bg9.png http://i66.tinypic.com/142yctx.png http://i64.tinypic.com/snlc08.png http://i64.tinypic.com/2n16vcw.png Part of key modifiers do not work in linux console. Mouse events working ok. Theme for console is to be improved a bit. Now I'm trying to get DlangIDE working in console. Best regards, Vadim

This is indeed really cool. How gracefully does it handle when the console is of limited size? Let's say 80x25. Does it allow e.g. virtual screen of bigger size and then moving around in console?

Keyboard support on Linux terminals seems most difficult. Some shortcuts are being processed by terminal app. Some ctrl-combinations are causing signals. I have an idea to catch some of Ctrl+key signals, and simulate keypress. E.g. I cannot get working text selection moving by Ctrl+Shift+Arrows. UI layout code required surprisingly a few changes. Most of console related fixes were made by providing separate theme file. Only hardcoded margins/padding/size limits were needed to fix.

Martin DlangUI provides "layouts" similar to Android ones, which should reflow and resize widgets for different screen sizes. As well, app may load layouts from DML markup file - different for different screen size (as it's done in Android). To simulate bigger screen, it's possible just to place controls inside ScrollWidget - and you would be able to move it with scrollbars.

Did you get my post about the keyboard thing? You can test it by running dub --single filename.d output looks like: kp: [27, 91, 49, 59, 50, 68] kp: [27, 91, 49, 59, 53, 68] kp: [27, 91, 49, 59, 51, 68] kp: [27, 91, 68] if I press: shift+Left ctrl+Left alt+left left BTW: love what you are doing with dlangui.

Now dlangui terminal mode supports only 16 colors. Some refactoring is required to support RGB colors.

But some combinations - do not. E.g. Ctrl+Shift+Left/Up/Down - at least in Gnome terminal. BTW: love what you are doing with dlangui. Are you a one person team? In general, yes. But there were 24 contributors who sent pull requests. Some of them contributed a lot of PRs - e.g. g4z3r(54 commits), MyLittleRobo(20 commits). It would be great if more developers joined dlangui. But it should become more usable and popular, to attract more people. One of stopper here is probably poor documentation.
