how to install DLangIDE on Debian Wheezy

how to install DLangIDE on Debian Wheezy:

 - get the source from here: or

git clone
cd dlangide
dub run

This will fail with

Derelict: cannot load freetype shared library: Failed to load symbol FT_Gzip_Uncompress from shared library


2015-02-23 16:16:06.462 E No font files found!!!
2015-02-23 16:16:06.463 E Currently, only hardcoded font paths implemented.
2015-02-23 16:16:06.463 E Probably you can modify sdlapp.d to add some fonts for your system.


Failed to load symbol SDL_HasAVX from shared library


SDL_CreateWindow failed - cannot create OpenGL window: No OpenGL support in video driver

No worries, will fix them next.

 - set the LD_LIBRARY_PATH to include /usr/local/lib if it does not include it already

export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH

 - install freetype from sources (configure, make, sudo make install) from here

 - install libxext-dev (required by SDL)

apt-get install libxext-dev

 - install libsdl2-dev from wheezy-backports: don't need it since we'll install from sources, but lots of other dependencies will be installed

apt-get -t wheezy-backports install libsdl2-dev

 - install SDL2 from sources (configure, make, sudo make install) from here

 - install ttf-dejavu ttf-dejavu-core ttf-dejavu-extra

apt-get install ttf-dejavu ttf-dejavu-core ttf-dejavu-extra

 - update dependencies

dub upgrade --force-remove

 - edit a file in DLangUI:

find the source for DLangUI in ~/.dub/packages/ and edit the file src/dlangui/platforms/sdl/sdlapp.d :

find the line "ft.registerFonts("/usr/share/fonts/dejavu/");" and add after it this line:


return to the folder with the sources for DLangIDE and run

dub build --force

and then

dub run



and you should get the main window to open

Did not get further today, will update this post if I get into more snags.

To get autocompletion install dcd from .

format json with Gedit and Perl

How to prettify/format/indent json with Gedit and Perl:

install JSON::XS
go to Plugins and enable "External tool"

go to Tools -> Manage External Tools -> add new (the button in the bottom on the left if no icons are shown)
add a name, for example "Format JSON with Perl"
replace the contents of the text area on the right with

#!/usr/bin/env perl 

use strict;
use JSON::XS;
local $/ = undef;
my $content = <STDIN>;

my $j = JSON::XS->new->utf8->pretty(1);
my $output = $j->encode($j->decode($content));

print $output;

open your file, then Tools -> External Tools -> "Format JSON with Perl"

you can also set a shortcut in the Manage External Tools window
