My Translator in ArchLinux+Awesome(2)

###Prefix 3 days ago I wrote a simple translator on my ArchLinux which could pop-up a notification window when I query a word. But when I use it at company it failed. Becaus the firewall has banned the communication to Google’s API. Thus I have to write another version of translator, which could get the result from the local database. ###Preparation python-stardict is a great library for querying word from stardict’s dictionary, you can get it via:

	$ git clone https://github.com/pysuxing/python-stardict.git

Also you have to download stardict’s dictionary from http://abloz.com/huzheng/stardict-dic/, you can choose whatever you like dictionary, then uncompress it into your python-stardict located directory. ###Coding Open stardict.py with your favorite editor, adding a function at the end of the file. The code snippet is listed as following:

def my_read_dict_info():
    """
    """
    my_ifo_file = "/home/Trusty/code/python/python-stardict/stardict-langdao-ec-gb-2.4.2/langdao-ec-gb.ifo"
    my_idx_file = "/home/Trusty/code/python/python-stardict/stardict-langdao-ec-gb-2.4.2/langdao-ec-gb.idx"
    my_dict_file = "/home/Trusty/code/python/python-stardict/stardict-langdao-ec-gb-2.4.2/langdao-ec-gb.dict.dz"
    #########Uncomment them for other dictionaries ######
    #my_dict_file = "stardict-dictd_www.dict.org_gcide-2.4.2/dictd_www.dict.org_gcide.dict.dz"
    #my_idx_file = "stardict-dictd_www.dict.org_gcide-2.4.2/dictd_www.dict.org_gcide.idx"
    #my_ifo_file = "stardict-dictd_www.dict.org_gcide-2.4.2/dictd_www.dict.org_gcide.ifo"

    #my_idx_file = "stardict-longman-2.4.2/longman.idx"
    #my_dict_file = "stardict-longman-2.4.2/longman.dict.dz"
    my_ifo_reader = IfoFileReader(my_ifo_file)
    my_idx_reader = IdxFileReader(my_idx_file)
    my_dict_reader = DictFileReader(my_dict_file, my_ifo_reader, my_idx_reader, True)
    cmdargs = str(sys.argv) ## args
    result = my_dict_reader.get_dict_by_word(str(sys.argv[1]))  ## Using args[1] for querying
    print result[0].values()[0]		## output result in terminal
    result_str = "\'<span color=\"green\" size=\"14000\">"+result[0].values()[0]+"</span>\'"	## Build the command line for notify-send
    #print result_str
    call(["notify-send", str(sys.argv[1]), result_str])		## Call notify-send to print on screen, last for 5 seconds
    #call(["echo", commandstr])
    #output = subprocess.check_output(["echo", commandstr])
    #p1 = subprocess.Popen(['echo','-e', commandstr], stdout=subprocess.PIPE)
    #p1 = subprocess.Popen(['printf', commandstr], stdout=subprocess.PIPE)
    #p2 = subprocess.Popen(['awesome-client', '-'], stdin=p1.stdout, stdout=subprocess.PIPE)
    #p1.stdout.close()
    #output = p2.communicate()[0]
    #print "*****"
    #print output

# read_ifo_file("stardict-cedict-gb-2.4.2/cedict-gb.ifo")
# read_idx_file("stardict-cedict-gb-2.4.2/cedict-gb.idx")
# read_dict_info()
my_read_dict_info()

Clean code:

    my_ifo_file = "/home/Trusty/code/python/python-stardict/stardict-langdao-ec-gb-2.4.2/langdao-ec-gb.ifo"

my_read_dict_info()

###Configuration You can add an alias into your ~/.bashrc

	alias mydict='python2 /home/Trusty/code/python/python-stardict/stardict.py'

Or you can add an executable file named /bin/mydic which contains:

#!/bin/bash
python2 /home/Trusty/code/python/python-stardict/stardict.py $@

###Result See the following images for result:

The query result will vanished in 5 seconds. ###TBD

• How to automatically record every query?
• How to replace the python-stardict with my own library(Written in C, much more fast?)?
• How to automatically judge english/chinese, or other languages?
• Considering Error Handling.

Things to be done in these days

There are following things to be done in recent days:

• Using a local dictionary for refering the words [Currently Done]
• SNMP on different equipments [Currently Done]
• Try installing and using FreeBSD/NetBSD [Currently Done]
• Using python to do image manipulation
• Using Python and other software to generate the big alubum pictures which contains different small pictures
• How to compare images using Linux scripts
• How to create a local search engine on my personal web server. [Currently Done]
• werc installation

This is an H1

Install SNMPD in OpenWRT

###Install snmpd

	$ opkg update && opkg install snmpd

The configuration file is /etc/config/snmpd, the configure file could be finetuned. while the file /etc/init.d/snmpd script will make snmpd program to load another cutom config
snmpd is too big for embedded system, so we use mini-snmpd for openwrt. ###Install mini-snmpd

	$ opkg update && opkg install mini-snmpd

The configuration file is located at /etc/config/mini_snmpd, edit this file,for enable the default configration from option enable 0 to option enable 1, this will make mini_snmpd start for default.
###Use cacti Server Monitor to view the result In Ubuntu, type:

	$ apt-get install cacti cacti-spine

After the installation, you should visiti http://Your_ip_address/cacti for loging, the username and password are “admin” by default, but you will be asked to change it after the first login.
Go to “Device” click add at the right top, this will ask you to add an equipment for monitoring.
Fill in the ip address and select the type to “Generic SNMP-enabled Host”, then add some additional notes if necessary.
You can use following command to get the snmpd status:

	[Trusty@XXXyyy ~]$ snmpwalk -c public -v 2c 10.0.0.1:161

snmp on Raspberry PI

I want to use snmp for administrating my raspberry PI, for example, its disk usage, cpu usage, and etc. following is the how-to of setting up the monitoring environment.
###Preparation

	$ apt-get upate && apt-get upgrade
	$ apt-get install apache2 php5 mysql-client mysql-server
You will be prompted to set a password for mysql root user.
	$ apt-get install php5-mysql php5-snmp rrdtool snmp snmpd

My Translator in ArchLinux+Awesome

###BackGround My requirement is quite simple: I read many english content based website everyday, this means I always encounter many unkown words. My solution is use a translatio software or directly refer them in translate.google.com. But all of these ways were time-consuming process: you have to switch to other software, or you have to open new tabs in your web brower. So do we have a more sufficient way for doing these steps? I used a whole morning of my saturday and finished this procedure.
###Preparation You have to install google translator for CLI in ArchLinux’s yaourt, you can choose git version or standard version , I choose git version:

	$ yaourt -S google-translate-cli-git

After the installation, you can refer to http://www.soimort.org/google-translate-cli/ for more detailed usage for this tool. For example:

	[Trusty@DashArch ~]$ trs {=zh} "Hello, world"
	你好，世界

###Using Notification under awesome Yes we can use “notify-send” to directly display something on the screen, but notify-send is not convinient for us to control its behavior,

	notify-send $title $result --icon=dialog-information

So we will use awesome’s own notification module, name naughty. But first we have to add a new globle variable in rc.lua which under your own configuration directory, mine is under:

[Trusty@DashArch ~]$ cat /home/Trusty/.config/awesome/rc.lua | more
-- Standard awesome library
-- Notification library
local naughty = require("naughty")
naughty1 = require("naughty")

If we directly using rc.lua’s local variable “naughty”, awesome will complaint it cannot find the variable thus cannot display notification.
The method for displaying notification via naughty is as: echo ‘naughty1.notify({title = “testing”, text = “naughty”})’ | awesome-client - Notice naughty1 is the newly added variable in our configuration file.
###Our own bash script

#!/bin/bash
# check parameters
EXPECTED_ARGS=1
if [ $# -lt $EXPECTED_ARGS ]
then
	echo "Usage: `basename $0` Your_Tranlate_Word"
	notify-send "null" "null" --icon=dialog-information
	exit -1
fi
title=$@
declare -a result1
result1=`trs {=zh} "$@"`
result=""
for var in ${result1[@]};do
	result=$result' '$var
done
echo "naughty1.notify({title = \"$title\", text = \"$result\", timeout = 5, height = 100, font = \"Verdana 20\", bg = \"BB68D9\", timeout=5})" | awesome-client -

###Result The script is called via:
when you are browsing the webpage, if you encounter the words, simply press mod4+r, it will call the ‘run’ window, input mytrans.sh “Your words” then you will get the notification window at the top right of your monitor. This window will last for 5 seconds, then vanished. the image is like following:

Finally we can enjoy the non-blocking thinking reading now.
