I am trying to setup better go development environment and decided to give vim-go a try (which also resulted in me replacing Vundle with Pathogen, which is much more straightforward). Installing everything was a breeze and I only encountered a problem when I tried to make tagbar work, because tagbar does not work with BSD ctags and requires Exuberant ctags 5.5.

The simplest way how to install exuberant ctags is with brew.

ondra@nb218 ~/Downloads/ctags-5.8
$ brew install ctags
Warning: You are using OS X 10.11.
We do not provide support for this pre-release version.
You may encounter build failures or other breakage.

However brew is still having problems running on 10.11 and many packages fail to build, ctags being on exception. So let’s see how we can deploy ctags into /usr/local without stepping on brew’s toys.

First of all, we need to determine the prefix to use via brew diy:

ondra@nb218 ~/Downloads/ctags-5.8
$ brew diy --name=ctags --version=5.8
--prefix=/usr/local/Cellar/ctags/5.8

Now you can use brew fetch to download the source for ctags or just download it from sourceforge. To get the source using brew, use:

ondra@nb218 ~/Downloads/ctags-5.8
$ brew fetch --build-from-source ctags

Anyhow, when you have the source extracted, run configure && make with the prefix from brew diy:

ondra@nb218 ~/Downloads/ctags-5.8
$ ./configure --prefix=/usr/local/Cellar/ctags/5.8
Exuberant Ctags, version 5.8
Darwin 15.0.0 Darwin Kernel Version 15.0.0: Sun Jul 26 19:48:55 PDT 2015; root:xnu-3247.1.78~15/RELEASE_X86_64 x86_64
checking whether to install link to etags... no

And link ctags via brew using brew link:

ondra@nb218 ~/Downloads/ctags-5.8
$ brew link ctags
Linking /usr/local/Cellar/ctags/5.8... 2 symlinks created

And you are done. When building is fixed for brew under 10.11 simply unlink ctags and use brew install as usual.

Qt Installer Framework is a quite new framework which is currently still in development. The current version contains set of tools and utilities to create installers. The most significant feature is that the framework itself is multiplatform, it supports Windows, Mac OS X and Linux.

Great feature of QT Installer Framework is that it can download the required files from the server. That means it is not required to provide files with the installer. It works with the so called “repositories”. Thanks to this it is also able to update the files without having to download the installer again, because it creates maintenance tool which can update or uninstall the files. However the documentation is not perfect, it is missing a lot of details.

The framework is an open source project. It is built on top of the Qt (it requires static built of Qt).

The framework is really easy to use. For the basic features the user needs to know to work with XML, that is all. For advanced features the knowledge of javascript (QtScript) is required (C++ might be required for the most advanced features).

Usage

Whole installer creation process starts with creating the required folder structure.

Screen Shot 2015-01-28 at 09.16.11

There are two main folders. The config and the packages folder.

Configuration

The config folder contains the installer configuration file (config.xml) and images used in the installer. There are various things that can be configured – Supported Configuration Settings. This is the example what the configuration file could look like:

<?xml version="1.0" encoding="UTF-8"?>
<Installer>
 <Name>YSoft SafeQ Mac Client</Name>
 <Version>4.3.0</Version>
 <Title>YSoft SafeQ Mac Client Installer</Title>
 <Publisher>Y Soft</Publisher>
 <ProductUrl>http://www.ysoft.com</ProductUrl>
 <TargetDir>@HomeDir@/YSoft</TargetDir>
 <AllowSpaceInPath>true</AllowSpaceInPath>
 <InstallerApplicationIcon>ysoft_96</InstallerApplicationIcon>
 <InstallerWindowIcon>ysoft_96_32x32</InstallerWindowIcon>
 <Watermark>modern-wizard.bmp</Watermark>
 <WizardStyle>Aero</WizardStyle>
</Installer>

Packages

The second folder is the package folder. It contains all components that will be installed by the installer. Every component consists of two folders, the data and the meta folder.

The data folder contains all the files that will be installed on the target machine. Installer archives all data to the 7z format and extracts it on installation.

The meta folder contains configuration file(package.xml) for the component and the installation script that will be called when the component is loaded.

This is the example file of component configuration file

<?xml version="1.0" encoding="UTF-8"?>
<Package>
 <DisplayName>CUPS Backend</DisplayName>
 <Description>CUPS Backend</Description>
 <Version>4.3.0</Version>
 <ReleaseDate>2015-01-23</ReleaseDate>
 <Default>true</Default>
 <Script>installscript.js</Script>
 <ForcedInstallation>true</ForcedInstallation>
 <RequiresAdminRights>true</RequiresAdminRights>
</Package>

and here is the full list of possible configuration values – Summary of Package Information File Settings.

The next file is the installation script file (installscript.js). The script is called when the installer is executed and the component is loaded. The script can add new installer wizard pages, prompt user for custom path for the component etc. This is example of a script that extracts component to the /tmp folder and moves it to the Application. Then it adds new item (log out checkbox) to the final page of the installer (the page items or pages have to be designed in Qt designer).

function Component(){
	//Connect signals to functions
	component.loaded.connect(this, componentLoaded);
	installer.finishButtonClicked.connect(this, finishClicked);
}

Component.prototype.createOperationsForArchive = function(archive){
	//Extract and move .app file
	component.addOperation("Extract", archive, "/tmp");
	component.addElevatedOperation("Execute","mv", "/tmp/YSoft\ SafeQ\ Client.app", "/Applications", 
								   "UNDOEXECUTE", "rm", "-rf", "/Applications/YSoft\ SafeQ\ Client.app");
}

componentLoaded = function(){
	//If this is installer load checkbox from .ui file
	if(installer.isInstaller()){
		installer.addWizardPageItem(component, "LogOutCheckBoxForm", QInstaller.InstallationFinished);	
	}
}

finishClicked = function(){
	if(!component.installed)
		return;
	//If the installation was succesful, let the user log out
	if(installer.isInstaller() && installer.status == QInstaller.Success){
		var isLogOutChecked = component.userInterface("LogOutCheckBoxForm").LogOut.checked;
        if (isLogOutChecked) {
			//Todo - logout
		}
	}
}

Here is the documentation for the Component scripting.

The installer is created by executing the Qt Installer tool

binarycreator -c config/config.xml -p packages installer

where -p is path to the packages folder and -c is path to the config.xml file. The last part is the name of the installer. 

This is the look of the final installer on Mac OS X:

Update: add information about IntelliJ Idea 14

Java is no longer part of Mac OS default installation. When you want to start Idea on new Mac OS Yosemite you’ll get this nice message:

yosemite-java6

You have two options. Install legacy Java 6 from Apple or install new Java 8 from Oracle.

IntelliJ Idea 13

In case of Java 8, just open file “/Applications/IntelliJ IDEA 13.app/Contents/Info.plist” and change JVMVersion from 1.6* to 1.8*:

sudo vim "/Applications/IntelliJ IDEA 13.app/Contents/Info.plist"

IntelliJ Idea 14

Open file “/Applications/IntelliJ IDEA 14.app/Contents/Info.plist” and change JVMVersion from 1.6* to 1.8*:

sudo vim "/Applications/IntelliJ IDEA 14.app/Contents/Info.plist"

intellij-jvm-1.8

Click IntelliJ Idea icon and enjoy your IDE.

Sometimes it is necessary to work only with text console.

Git provides rich command line interface, but browsing history is little bit cumbersome.

If you like command line tools and email client mutt then there is awesome tool for you: tig.

tig is text mode interface for git.

Just enter directory with cloned git repo and type:

tig

tig-example

Quick navigation:

  • Enter – show details
  • Tab – switch window pane
  • q – quit
