Syntax Highlighting, Deteksi Tipe File, dan Indentasi untuk Scala di Vim

Default vim di Arch Linux tidak menyertakan file-file scala.vim untuk syntax, ftdetect, dan indent. Berikut ini adalah langkah-langkah yang saya lakukan untuk meng-enable penggunaan Scala di Vim.

Buat Directory

[bpdp@bpdp-arch ~]$ mkdir .vim
[bpdp@bpdp-arch ~]$ cd .vim
[bpdp@bpdp-arch .vim]$ mkdir ftdetect
[bpdp@bpdp-arch .vim]$ mkdir indent
[bpdp@bpdp-arch .vim]$ mkdir syntax
[bpdp@bpdp-arch .vim]$ ls -la
total 20
drwxr-xr-x  5 bpdp users 4096 2009-09-17 06:27 .
drwx------ 95 bpdp users 4096 2009-09-17 06:26 ..
drwxr-xr-x  2 bpdp users 4096 2009-09-17 06:23 ftdetect
drwxr-xr-x  2 bpdp users 4096 2009-09-17 06:27 indent
drwxr-xr-x  2 bpdp users 4096 2009-09-17 06:26 syntax
[bpdp@bpdp-arch .vim]$ 

Mengambil file-file yang diperlukan

File-file tersebut berada di trunk svn berikut: https://lampsvn.epfl.ch/trac/scala/browser/scala-tool-support/trunk/src/vim dan bisa diambil via web melalui trac. Disini saya menggunakan wget untuk langsung mengambil file-file tersebut:

syntax

[bpdp@bpdp-arch syntax]$ cd ../ftdetect/[bpdp@bpdp-arch ftdetect]$ wget https://lampsvn.epfl.ch/trac/scala/export/18712/scala-tool-support/trunk/src/vim/ftdetect/scala.vim

indent

[bpdp@bpdp-arch ftdetect]$ cd ../indent/
[bpdp@bpdp-arch indent]$ wget https://lampsvn.epfl.ch/trac/scala/export/18712/scala-tool-support/trunk/src/vim/indent/scala.vim

[bpdp@bpdp-arch indent]$

Proses di atas akan menghasilkan file-file berikut ini:

[bpdp@bpdp-arch .vim]$ ls -laR

[bpdp@bpdp-arch .vim]$ 

Setelah itu vim/gvim bisa digunakan untuk mengedit file source code Scala. Berikut ini adalah contoh screenshot:

Pada vim, tampilannya adalah sebagai berikut:
