There are still a lot of things I can +(try to) do, but the "story" is over. + +So, at the start of this game you are a legendary knight and you go +into this castle, for what reason is not explained until later. This +game is about his children, somehow. At the end of the tutorial the +knight dies and a child of his will take his place and walk into the +very same castle, possibly to avenge their father. + +Each time you die you get to pick a new child to work with, each has a +class which affects certain stats and each may have one or two traits. +These traits can be useful, funny, annoying or sometimes even make you +sick. Some traits include being near-sighted, having no pulse in your +feet or being a giant. They make for some interesting experiences and +some laughs as well. Classes include a Paladin which isn't +particularly good at anything, an Archmage which has a lot of magic +power, and a Knave which is pretty bad at everything except has a +killer critical hit. + +Every time you enter the castle it will normally be completely +different from last time, save for a few constants. In my opinion this +makes it vastly replayable, as every time you have to start over +everything is new. + +Thankfully this is not such a cruel game that every time you die you +have to start over from scratch. Each run through the castle will +result in some gold, this gold can be used by the next generation to +buy some upgrades, and thus level up. So even if you are exceptionally +bad at a game like this, as I probably am myself, you'll still be able +to make progress simply by trying over and over again. Of course there +are also better armors and weapons to be bought and runes to be +equipped to help you even more. + +The gameplay is very nice. It's very action/platform in nature as +there is a lot of swinging of the sword, dodging of projectiles and +jumping on platforms to be had. + +# Installation on linux + +The game is available for linux, although since I bought it through +gog.com I only had an option of windows or mac.

Again there's some +communication involved here, because both sides will have to share a +repository with the same name. If either side doesn't share a +repository with the other side, it won't sync. After you've +communicated which names to use, though, all should go smoothly. It +check once every 60 seconds whether or not anything's changed and if +it has it'll try and sync with the other machine(s). + +One downside to this program, at least on Linux, compared to ownCloud, +at least using the ownCloud Client, is that there is no notification +of newly arrived files. So again you'd have to send the person owning +the node you're sharing with a message telling them that something new +should be waiting for them. + +A very nice thing on the other hand, is that everything is encrypted. +And because there's no central server involved, only the people you +choose to share with (and possibly they choose to share with) will +have the files.

+ +My `.travis.yml` is pretty simple: + +``` +language: erlang + +env: + - LUA="lua" + +branches: + except: + - gh-pages + +install: + - sudo apt-get update + - sudo apt-get install luarocks libssl1.0.0 + - sudo luarocks install busted + - sudo luarocks install luasocket + - sudo luarocks install luasec OPENSSL_LIBDIR=/usr/lib/x86_64-linux-gnu + - sudo luarocks install luajson + - sudo luarocks install luaposix + +script: "busted -m 'lua/?.lua' -o TAP" + +# ... +``` + +I'm using the `erlang` environment, because there isn't a Lua one +(yet). I've written my library for lua, not luajit, so busted needs to +know which to run, it always runs luajit first it seems. I don't need +the tests to be run again when the `gh-pages` branch is updated, since +that has nothing to do with the code itself, I would actually like to +have tests run on all other branches. + +Then we get to the dependencies. Nothing major except for the luasec +dependency. I'm not entirely sure how long that `OPENSSL_LIBDIR` will +remain where it is now, but it works for now. I didn't discover the +location myself, I found it on +[someone else's](https://github.com/ignacio/redis-luanode/blob/a50a7e5a9d0bd0c61b6ce7e445b278f2f184c792/.travis.yml#L41) +`.travis.yml` as a comment. + +Lastly we have the script. Since the tests live in `/spec` and the +code lives in `/lua` I run the tests from the project root and include +the `lua` directory in the module path. I use TAP output because with +the default output failures also return `0`, when a failure occurs +with the TAP output, a non-0 exit status is returned and travis knows +they didn't pass. That is why build 6 passed even though there was +still a failed test. + +The rest is notification settings which isn't interesting enough to +duplicate here. + +# Still to do + +Now I should start expanding it a little. Well, actually I *still* +need to add the proper license information. + + + + diff --git a/there-is-an-evil-in-your-emacs.post b/there-is-an-evil-in-your-emacs.post new file mode 100644 index 0000000..537b5b2 --- /dev/null +++ b/there-is-an-evil-in-your-emacs.post @@ -0,0 +1,68 @@ +;;;;; +title: There is an Evil in your Emacs +tags: emacs, vim, editors +date: 2014-07-01 21:44 +format: md +;;;;; + +When I first started using GNU/Linux I was looking for a proper text +editor. I only had any experience with Visual Studio on Windows +because I was a .Net developer at the time, and didn't really have +much of a choice. One of the main things I wanted was an editor that +worked in a terminal. + +Naturally I came to Vim and Emacs (as well as Nano, and perhaps some +others as well). For a few weeks I kept switching between Vim and +Emacs. I liked Vim's syntax highlighting better, but on the other hand +I liked Emacs' keybindings/modelessness better as well. I ended up +going with Emacs mostly because of Vim's moded editing. + +For years the thought of Vim's moded editing gave me nightmares. I +never really realised the best thing about Vim. Even when a post +appears on Stack Overflow about grokking Vim. I was already so blinded +by the idea that Emacs was the superior editor for me that I failed to +register the information. It took a long time, but eventually I opened +up to the possibility of such moded editing. By now I was stuck with +Emacs because I just couldn't give up its customizability or +extensibility. Also, I've grown to love Lisp, and specifically Emacs +Lisp, so to go from that to Vimscript wouldn't be quite ideal. + +Eventually I decided I really did want to try it. Thankfully Emacs has +a package for that: Evil, the Extensible Vi Layer for Emacs. There is +one other problem, though: I use the Colemak keyboard layout. The +usual `hjkl` keys are more like `hynu`, with the up key at the bottom +of the keyboard, down at the top and left and right diagonally from +eachother. Again Emacs has a package for that, `colemak-evil`. It +rebinds some of the keys so that Evil will work with the Colemak +keyboard layout. It is based on that the creator of the Colemak layout +used to use in Vim. It's a bit aggressive, so I customized it to be a +little less so, mostly removing rebindigs from the motion and emacs +state maps. + +The real power is in the composability of the commands. In Emacs you +have commands like `forward-kill-word`, `forward-kill-sexp` and +`forward-kill-char`. In Vim you have the `delete` operation, which can +be combined with, for example, the `forward-word` motion, or the +`next-line` or `forward-char` motion. I probably have the names wrong, +but hopefully they convey the meaning of what they do. This is what it +is all about, or at least from what I've learned to use so far. Of +course the powerful ed-like editing features called forth through the +Vim `ex` mode, such as `%s/find/replace`. Lastly, of course, the fact +that a lot of editing can be done in normal mode helps in preventing +Emacs-pinky. + +I haven't yet been able to work with the extensible part, but some of +the modules that exist for evil speak volumes of it. + +If you are interested in increasing your productivity, or you like to +experiment with new things, you might really want to try it. It may +not completely be Vim, but it's still completely Emacs. If you use the +colemak-evil package as well you'll also notice that in the insert +state all your regular Emacs keys work normally, which is a great +combination of the two editors. So far I feel that Vim is great for +editing existing code and text, but Emacs still feels better when +writing a lot of new code or text. + + + +
