# Installation ## Requirements In its bid for minimalism, Textadept also needs very little to run. In fact, the only thing it needs is [GTK+][] >= 2.18 on Linux systems. GTK is already included in Windows and Mac OSX packages. Textadept also has its own version of Lua. The _experimental_ terminal version of Textadept requires [ncurses][]. This dependency is only necessary if you wish to run Textadept from a terminal. Notes: * The Linux binaries provided require GLib >= 2.28 to support single-instance functionality. You can compile Textadept with earlier versions of GLib down to 2.22. For reference, Ubuntu 11.04, Debian Wheezy, Fedora 15, and openSUSE 11.4 support GLib 2.28 or higher. * For Win32 and Mac OSX, more than 3/4 of the download and unpackaged application sizes are due to GTK+, the cross-platform GUI toolkit Textadept uses. Textadept itself is much smaller. [GTK+]: http://gtk.org [ncurses]: http://invisible-island.net/ncurses/ncurses.html ### Linux Most Linux systems already have GTK+ installed. If not, it is probably available through your package manager. Otherwise, compile and install it from the [GTK+ website][]. Most Linux systems already have ncurses installed. If not, look for it in your package manager, or compile and install it from the [ncurses website][]. For Debian-based distributions like Ubuntu, the package is typically called `libncursesw5`. Note: you should have a version of ncurses compiled with "wide" (multibyte) character support installed.

Select the appropriate package for your platform. You can also download an official set of [language-specific modules][], but this is optional. The list of language modules in the package is contained [here][]. Textadept includes C/C++ and Lua language modules by default. [project page]: http://foicica.com/textadept [language-specific modules]: 7_Modules.html#Language.Specific [here]: http://foicica.com/hg ## Installation Textadept is designed to be as easy as possible to install by any user. You do not need to have administrator privileges. ### Linux Unpack the archive anywhere. If you downloaded the set of language-specific modules, unpack it where you unpacked the Textadept archive. The modules will be contained in `/path/to/textadept_VERSION/modules/`. ### Mac OSX Unpack the archive and move `Textadept.app` to your user or system `Applications` directory like any other Mac OSX application. There is also a `ta` script for launching Textadept from the command line that you can put in your `PATH`, but this is optional. If you downloaded the set of language-specific modules, unpack it, right-click `Textadept.app`, select `Show Package Contents`, navigate to `Contents/Resources/modules`, and copy the unpacked modules there. ### Windows Unpack the archive anywhere. If you downloaded the set of language-specific modules, unpack it where you unpacked the Textadept archive. The modules will be contained in `textadept_VERSION\modules\`. ## Running ### Linux Run Textadept by running `/path/to/textadept_VERSION/textadept` from the terminal. You can also create a symlink to the executable in your `PATH` (e.g. `/usr/bin`) or make a GNOME, KDE, XFCE, etc. button or menu launcher. There is also a `textadeptjit` executable for running Textadept with [LuaJIT][]. Please note there may be [compatibility issues][]. The `textadept` executable is recommended. The `textadept-ncurses` and `textadeptjit-ncurses` executables are versions of Textadept for the terminal. [LuaJIT]: http://luajit.org [compatibility issues]: 11_Scripting.html#LuaJIT #### Problems It is difficult to provide a single binary that runs on all Linux platforms since the versions of software installed vary widely from distribution to distribution. Because the Linux version of Textadept uses the version of GTK+ installed on your system, an error like: `error while loading shared libraries: : cannot open shared object file: No such file or directory` may occur when trying to run the program. The solution is actually quite painless even though it requires recompiling Textadept. See the [compiling][] page for more information. [compiling]: 12_Compiling.html ### Mac OSX Run Textadept by double-clicking `Textadept.app`. `Textadept.app` also contains an executable for running Textadept with [LuaJIT][]. You can enable it by setting a `TEXTADEPTJIT` [environment variable](#Environment.Variables) or using `export TEXTADEPTJIT=1` in the terminal. Please note there may be [compatibility issues][]. The non-LuaJIT executable is recommended. [LuaJIT]: http://luajit.org [compatibility issues]: 11_Scripting.html#LuaJIT #### Environment Variables By default, GUI apps like Textadept do not utilize environment variables such as `PATH` from your shell profile. Therefore, any [modules][] that use programs contained in `PATH` (e.g. the progams in `/usr/local/bin/`) for run and compile commands will not be found. The solution is to follow these [instructions][] to export whichever environment variables you need. At the very least, set `PATH` to be `$PATH`. You will have to logout and log back in for the changes to take effect. [modules]: 7_Modules.html [instructions]: http://developer.apple.com/library/mac/#qa/qa1067/_index.html ### Windows Run Textadept by double-clicking `textadept.exe`. You can also create shortcuts to the executable in your Start Menu, Quick Launch toolbar, Desktop, etc. There is also a `textadeptjit.exe` executable for running Textadept with [LuaJIT][]. Please note there may be [compatibility issues][]. The `textadept.exe` executable is recommended. [LuaJIT]: http://luajit.org [compatibility issues]: 11_Scripting.html#LuaJIT ## Single Instance Textadept is a single-instance application on Linux, BSD, and Mac OSX. This means that after Textadept is opened, running `textadept file.ext` (`ta file.ext` on Mac OSX) from the command line or opening a file with Textadept from a file manager will open `file.ext` in the already open instance of Textadept. You can override this and open the file in a new instance by passing a `-f` or `--force` switch to Textadept: `textadept -f file.ext` (`ta -f file.ext`). When the force switch is not present, files will be opened in the original Textadept instance, regardless of how many instances are open. Single instance is not supported on the Windows and terminal versions of Textadept. ![Linux](images/linux.png)    ![Mac OSX](images/macosx.png)    ![Win32](images/win32.png)
