reducing usage of set/variable

Post by ComputerTech »

Anyway possible to not use variable soo many times, maybe like this.

Code: Select all

foreach {foo bar moo} [split $args] {break}
For this code

Code: Select all

namespace eval CT-IP {

############################
#  Start of configuration  #
#--------------------------#

##########################
# Trigger
##
variable trig "!ip"

##########################
# API 
##
variable api "2bbd882cec5fa5f26d53fe6049a21343"


##########################
# Flags
##
# n = Owner
# m = Master
# o = Op
# h = Halfop
# v = Voice
# f = Friend
# - = Everyone
##
variable flag "-|-"


##########################
# Output
##
# M = Message
# N = Notice
# N = Nick
# C = Channel
##
variable outp "MC"

 
############################
#   End of configuration   #
#--------------------------#

###############################################################################

variable author "ComputerTech"
variable version "v0.1"
variable name "CT-IP"

package require http
package require json

bind PUB $flag $trig [namespace current]::IP:proc

proc putout {text} {
	variable outp
	upvar 1 nick nick chan chan
	switch -- [string index $outp 0] {
		"M" {variable action "PRIVMSG"}
		"N" {variable action "NOTICE"}
	}
	switch -- [string index $outp 1] {
		"N" {variable target $nick}
		"C" {variable target $chan}
	}
	putserv "${action} ${target} :$text"
}

proc IP:proc {nick host hand chan text} {
 variable api
 variable url "http://api.ipstack.com/"
 variable params [::http::formatQuery q [lindex $text 0] $api]
 variable data [http::data [http::geturl "$url?$params" -timeout 10000]]
      variable data2 [::json::json2dict $data]
      http::cleanup $data2
  variable ip [dict get $data2 "ip"]
  variable hostname [dict get $data2 "hostname"]
  variable type [dict get $data2 "type"]
  variable continent [dict get $data2 "continent_name"]
  variable country [dict get $data2 "country_name"]
  variable region [dict get $data2 "region_name"]
  variable city [dict get $data2 "city"]
  variable latitude [dict get $data2 "latitude"]
  variable longitude [dict get $data2 "longitude"]
  variable location [dict get $data2 "location"]
  variable language [dict get $location "languages"] 
  variable name [dict get $language "name"]
putout "\002IP\002: $ip | \002Hostname\002: $hostname | \002Type\002: $type"
putout "\002Continent\002: $continent | \002Country\002: $country | \002Region\002: $region"
putout "\002City\002: $city | \002Latitude\002: $latitude | \002Longitude\002 $longitude |\002Language\002 $name"
  }
putlog "$name $version by $author Loaded!"
}
Imo it looks messy with multiple usage of variable or set
thanks in advanced :P

You don't want to name all the variables in the dict ?

Code: Select all

foreach varname [dict keys $data2] {
   set ip($varname) [dict get $data2 $varname]
}
And after, use $ip(ip), $ip(hostname), ...

He said

Code: Select all

set ip($varname) [dict get $data2 $varname]
and you used:

Code: Select all

variable ip($varname) [dict get $data2 $varname]
To make it less confusing I would replace varname with key, since that's what you are looping over the keys from that dictionary.
Once the game is over, the king and the pawn go back in the same box.

Still don't understand why it generates a error in Partyline.

Code: Select all

Most likely cos you are doing a cleanup on $data2, instead of $data.. anyway your variables confuses me so I made it from scratch.

Code: Select all

proc IP:proc {nick host hand chan text} {
	variable api
	if {[scan $text {%s} ip] < 1} return
	set url "http://api.ipstack.com/$ip?access_key=$api&hostname=1"
	catch {set http [::http::geturl $url -timeout 6000]} error
	set data [::http::data $http]
	set dict [::json::json2dict $data]
	::http::cleanup $http
	foreach key [dict keys $dict] {
		set result($key) [dict get $dict $key]
	}
	putout "$result(ip)"
}
Once the game is over, the king and the pawn go back in the same box.
