How to add Go support to Geany

I am trying to make syntax hightlighting and building options work for Geany, any advice?

I just noticed this page: http://go-lang.cat-v.org/text-editors/geany/

Seems like they've got everything you need right there.

Look in $GOROOT/misc and http://go-lang.cat-v.org/text-editors/ for syntax files from other editors to get an idea.

Barring that, start with C or C++ and add/substract things like <code>go</code>, <code><-</code>, <code>func</code>, etc.

Here is the Geany formatting Instructions posted by Steve Horsley to golang-nuts:

1. In Geany, goto Tools->Configuration Files->filetype_extensions.conf and add in the following new heading:

   Go=*.go;
   

2. Copy the C definition filetypes.c to filedefs/filetypes.Go.conf:

   cp /usr/share/geany/filetypes.c ~/.config/geany/filedefs/filetypes.Go.conf
   

3. Edit filetypes.Go.conf and change the setting and keywords sections to this:

   [settings]
   # default extension used when saving files
   extension=go
   lexer_filetype=C
   
   [keywords]
   # all items must be in one line
   primary=break case chan const continue default defer else fallthrough for func go goto if import interface map package range return select struct switch type var
   secondary=byte int int8 int16 int32 int64 uint uint8 uint16 uint32 uint64 float32 float64 complex64 complex128 uintptr string
   

Have you defined the Go filetype in ~/.config/geany/filetype_extensions.conf ?

[Extensions]
...
Go=*.go
...

if the conf file doesn't yet exist, copy it from /usr/share/geany and add that line under 'Extensions' (or look for it under Tools > Configuration Files).

I made a Python script that automates the directions in the link provided by Jaybill McCarthy.

import shutil, re, os

HOME = os.environ['HOME']

shutil.copy('/usr/share/geany/filetype_extensions.conf', HOME +'/.config/geany/')
with open(HOME + '/.config/geany/filetype_extensions.conf', 'r') as f:
    fileData = f.read()
fileData = re.sub(r'Haskell=.*;', r'Go=*.go;\nHaskell=*.hs;*.lhs;', fileData)
fileData = re.compile('(\[Groups\][^\[]Programming=.*?$)', re.DOTALL|re.MULTILINE).sub(r'Go;', fileData)
with open(HOME + '/.config/geany/filetype_extensions.conf', 'w') as f:
    f.write(fileData)


textSettings = """[settings]
extension=go
lexer_filetype=C
comment_single=//
comment_open=/*
comment_close=*/
comment_use_indent=true
"""
textKeywords = """[keywords]
primary=break case chan const continue default defer else fallthrough for func go goto if import interface map package range return select struct switch type var
secondary=byte int int8 int16 int32 int64 uint uint8 uint16 uint32 uint64 float32 float64 complex64 complex128 uintptr string"""

shutil.copy('/usr/share/geany/filetypes.c', HOME + '/.config/geany/filedefs/filetypes.Go.conf')
with open(HOME + '/.config/geany/filedefs/filetypes.Go.conf', 'r') as f:
    fileData = f.read()
fileData = re.compile(r'\[settings\].*?^\[', re.DOTALL|re.MULTILINE).sub('%s\n\n[' %textSettings, fileData)
fileData = re.compile(r'\[keywords\].*?^\[', re.DOTALL|re.MULTILINE).sub('%s\n\n[' %textKeywords, fileData)
with open(HOME + '/.config/geany/filedefs/filetypes.Go.conf', 'w') as f:
    f.write(fileData)

print "Complete!"

I'm not sure if this means I am lazy, or the other way around... o.O.
