Qmind 0.0.10

Thu, 03 Jan 2013 21:18:34 +0100

Over the last two weeks I found some time to work on my small Cocoa project Qmind, a mind-mapping app for OS X:

Finally, arrow keys can be used to change the selection. And icons can be inserted. However, the deletion of icons will come in version 0.0.10 + X, where X > 0.

Node.js Static HTTP Server

Sat, 29 Dec 2012 21:15:55 +0100

Since http://qvacua.com consists of only static files, the following node.js static HTTP server comes in handy

HOST = null; // null => localhost
PORT = 8000;

HTTP_STATUS_OK = 200;
HTTP_STATUS_NOT_FOUND = 404;

var http = require("http"),
    url = require("url"),
    path = require("path"),
    fs = require("fs");

function writeNotFound(response) {
    response.writeHead(HTTP_STATUS_NOT_FOUND, {
        "Content-Type": "text/plain"
    });
    response.end("Not Found");
}

function writeBinary(data, response) {
    response.writeHead(HTTP_STATUS_OK);
    response.write(data, "binary");
    response.end();
}

function writeIndexHtml(filename, response) {
    var indexFilename = path.join(filename, 'index.html');

    fs.exists(indexFilename, function (exists) {
        if (!exists) {
            writeNotFound(response);
            return;
        }

        fs.readFile(indexFilename, function (error, data) {
            writeBinary(data, response);
        });

    });
}

var server = http.createServer(function (request, response) {
    var uri = url.parse(request.url).pathname;
    var filename = path.join(process.cwd(), uri);

    fs.stat(filename, function (error, stats) {
        if (error) {
            writeNotFound(response);
            return;
        }

        if (stats.isDirectory()) {
            writeIndexHtml(filename, response);
            return;
        }

        fs.readFile(filename, function (error, data) {
            writeBinary(data, response);
        });
    });
});

server.listen(PORT, HOST);
console.log("Server @ http://" + (HOST || "localhost") + ":" + PORT);

By default index.html will be served when the URL directs to a folder. It does not have error handling whatsoever: sufficient for development.

Mocking Class Method in Objective-C

Fri, 21 Dec 2012 22:04:22 +0100

Once in a while, when testing your Objective-C code, you want or have to mock a class method. Or you want to replace the implementation of a class method. The following code replaces the implementation of originalClassMethod of SomeClass with the implementation of mockClassMethod of MockClass:

Method mockMethod = class_getInstanceMethod([MockClass class], @selector(mockClassMethod));
IMP mockImpl = method_getImplementation(mockMethod);
Method originalMethod = class_getClassMethod([SomeClass class], @selector(originalClassMethod));
IMP originalImpl = method_setImplementation(originalMethod, testImpl);

Don’t forget to import objc/runtime.h.

"Wir werden ihm, diesem unseren Staat, das geben, dessen er bedarf. Seine Autorität, wo immer sie..."

Sun, 02 Dec 2012 10:26:11 +0100

“Wir werden ihm, diesem unseren Staat, das geben, dessen er bedarf. Seine Autorität, wo immer sie gebraucht wird, legitimiert sich allein aus dem Grundgesetz und aus den von den Volksvertretungen beschlossenen Gesetzen. Wir werden unseren Staat weder den Kurzschlüssen der Panik noch den Interessen privilegierter Gruppen ausliefern. Recht und Gesetz beruhen nicht primär auf Justiz und Polizei, so lebensnotwendig beide Institutionen sind und so sehr sie des Verständnisses und der Unterstützung aller Bürger bedürfen. Recht und Gesetz beruhen zuallererst auf der Gerechtigkeit: Schutz der Schwachen, Bändigung der Mächtigen und der übermütigen; sie erfordern einen Staat, der das Notwendige — mit Hilfe klarer Gesetze und einer effektiven Verwaltung — auch gegen die geballten Interessen von Privilegierten durchsetzen kann.”

- Willy Brandt, 12. Oktober 1972

"Chief among these was the stoning to death of adulterers, a punishment which has absolutely no..."

Mon, 26 Nov 2012 21:33:22 +0100

“Chief among these was the stoning to death of adulterers, a punishment which has absolutely no foundation whatsoever in the Quran but which Umar justified by claiming it had originally been part of the Revelation and had somehow been left out of the authorized text. Of course, Umar never explained how it was possible for a verse such as this “accidentally” to have been left out of the Divine Revelation of God, but then again, he didn’t have to.”

Continuous Integration for Cocoa Reloaded

Sun, 25 Nov 2012 16:38:43 +0100

First do the following:

Open the “Manage Schemes…” dialog and check “Shared” for schemes you want to have available for Jenkins. Xcode generates “xcshareddata” folder inside the xcodeproj file.
Open “Build Settings” for the test target and set “Bundle Loader” and “Test Host” to blank by deleting them.
Create a free-style job.

For tests using OCUnit:

Download ocunit2junit and put it somewhere.
Add an “Execute shell” build step and insert the following
xcodebuild -scheme NAME_OF_TEST_SCHEME -configuration Debug clean test | /PATH/TO/ocunit2junit
Add the “Publish JUnit test result report” post-build action with **/test-reports/*.xml

For static analysis using clang-analyzer:

Download clang-analyzer and put it somewhere.
Install “Clang Scan-Build Plugin” for Jenkins
Add an “Execute shell” build step and insert the following
/PATH/TO/scan-build -k -v -v -o clangScanBuildReports xcodebuild -scheme NAME_OF_SOME_SCHEME -configuration Debug clean build
Add the “Publish Clang Scan-Build Results” post-build action
