with some modification to my weather script, you can now call data directly from the conkyrc

conkyrc

lua_load ~/lua/forecast.lua
lua_draw_hook_pre weatherdata#starts the lua weather data gathering function, call once at top of conkyrc

TEXT
Current
Conditions: ${lua weather now.con}
Humidity: ${lua weather now.hum} %

${lua weather day1.day}
Conditions: ${lua weather day1.con}
High: ${lua weather day1.hih} F
Low: ${lua weather day1.low} F

${lua weather day2.day}
Conditions: ${lua weather day2.con}
High: ${lua weather day2.hih}
Low: ${lua weather day2.low}

${lua weather day3.day}

Low: ${lua weather day5.low}

${lua weather day10.day}
Conditions: ${lua weather day10.con}
High: ${lua weather day10.hih}
Low: ${lua weather day10.low}

CPU: ${cpu}

it gives you current info with these options
--current info.. use now.option

wch=wind chill
cel=ceiling
hid=heat index
vis=visibility
dpt=dew point
wsp=wind speed (in mph)
wdg=wind direction in degrees
wdi=wind direction NSEW
wgs=wind gusts
hum=humidity
prs=pressure

and forecast info 10 days with these options
--options used dayX.option, where X is 1 to 10 , 1 is todays forcast
day=forecast day and date
con=conditions summary
hih=high temp
low=low temp
sri=sunrise
sst=sunset
mri=moon rise
mst=moon set
uvi=ultraviolet index
hum=humidity
ppt=chance of precipitation

cld=cloud cover
mph=moon phase
wmh=wind speed in mph
wkm=wind speed in km/h
wkt=wind speed in knots
wdg=wind direction in degrees
wdi=wind direction in nesw

the lua script can be found here

you have to killall conky and restart when you make changes in the conkyrc
no weather images or weather font output as yet

you shouldnt have to kill and restart every time you make a change and save the conkyrc

the bits of conkyrc that give me the above output

I am still working on the icons. Before Weather.com charged, intellicast.com was the fee-based TWC feed and they set robots.txt to block parsing images/

I wonder if this is related... let me copy some icons in weathericons and try again.

2 problems with line 380
i put in a variable called daynight which seemed like a good idea at the time, but now i realise it wont work without further modifications so delete "..daynight" from line 380
here

(string.gsub(now.con,"[ %.%/]","")..daynight))())

becomes

(string.gsub(now.con,"[ %.%/]","")))())

you can delete the corresponding brackets too, but that isnt necessary

the other problem is that intellicast uses a lot of varied terms in its conditions summaries
many more than were found in the conkyforecast.py script
so im on the hunt for rogue conditions

Overcast needs to be added to the table wimage, starting on line 311
i put it under Cloudy and gave it the same icon (line 343)

Cloudy=26,
Overcast=26,
MostlyCloudyn=27, -- night

EDIT
i modified the wimage table so that each type of weather has a day version and a night version
and reimplemented a better version of the daynight icon switcher

updated lua script here
http://crunchbanglinux.org/pastebin/1305

if you want to maintain your own table if you come across a new weather type, then enter it twice
like so
(no spaces or periods and i believe you need to be case sensitive
also the script shortens Thunderstorm to T.Storm which would be TStorm in the table)

type=XX,
typen=XX,

and let me know what types and which icons you assigned them if you do smile

mrpeachy, I prefer to continue here on The Dark Side if you will.

The omploder tool is more handy and not as many distractions from questions.

I did PM you my iconset and zip file for all the intellicast icons I could wget.

mrpeachy · 2011-11-16 17:57:10

ive started a thread re my weather script for conky
if anyone tries the scripts and runs into problems or can help me identify intellicast weather types smile
i think im going to stick with translating weather types to icons

I continue to be in absolute amazment mrpeachy at what you are able to cook up. I'm still quite a way (ok, a long way) from getting some of these more elaborate conkys. This is the finished product of what I have been doing with my laptop. (ok, let's be honest....Configuring is NEVER finished smile )The info conky I pretty much wrote from scratch. It's a basic set up, nothing you have not seen on a bunch of different conkys. The weather is from Teo's accuweather script as well as another script from the Arch Linux board that shows the current condition and temp. The date on the bottom right of course I got from Sector11. All I have pretty much done with the weather conky is mess with the fonts and colors to make everything match plus added additional code to the conkyrc to give me the 5th day of weather. The Arch Linux Logo in the center is actually a conky calling to one letter from the OpenLogos font. Tint2 changed up also with the red border to match everything else. Starting to get involved in the OpenBox menu.xml. I have read that it is highly configurable. Need to figure out how to make it Red and White as well. I started a thread in the WM/DE talk forum about how others have configured their menus but it has yet to take off. OpenBox menu thread

All the best everyone and enjoy your weekend!!

Sector 11 has this in his latest conky

# killall conky && conky -c ~/Conky/Forecast_v5.conky &
# To use #! in a conky use: ${exec echo '#!'}

I have #! Statler on the G60 and need to know how this is used with #!

Use what?

killall works the same..

the second line is how to use the characters #! in a conky

--[[ RINGS with SECTORS widget
    v1.1 by wlourf (07 Jan. 2011)
    this widget draws a ring with differents effects 
    http://u-scripts.blogspot.com/2010/08/rings-sectors-widgets.html
    
To call the script in a conky, use, before TEXT
    lua_load /path/to/the/script/rings.lua
    lua_draw_hook_pre main_rings
and add one line (blank or not) after TEXT


Parameters are :
3 parameters are mandatory
name        - the name of the conky variable to display,
              for example for {$cpu cpu0}, just write name="cpu"
arg            - the argument of the above variable,
              for example for {$cpu cpu0}, just write arg="cpu0"
                arg can be a numerical value if name=""
max            - the maximum value the above variable can reach,
              for example for {$cpu cpu0}, just write max=100
    
Optional parameters:
xc,yc        - coordinates of the center of the ring,
              default = middle of the conky window
radius        - external radius of the ring, in pixels,
              default = quarter of the width of the conky window
thickness    - thickness of the ring, in pixels, default = 10 pixels
start_angle    - starting angle of the ring, in degrees, value can be negative,
              default = 0 degree
end_angle    - ending angle of the ring, in degrees,
              value must be greater than start_angle, default = 360 degrees
sectors        - number of sectors in the ring, default = 10
gap_sectors - gap between two sectors, in pixels, default = 1 pixel
cap            - the way to close a sector, available values are
                "p" for parallel , default value 
                "r" for radial (follow the radius)
inverse_arc    - if set to true, arc will be anticlockwise, default=false
border_size    - size of the border, in pixels, default = 0 pixel i.e. no border
fill_sector    - if set to true, each sector will be completely filled,
              default=false, this parameter is inoperate if sectors=1
background    - if set to false, background will not be drawn, default=true
foreground    - if set to false, foreground will not be drawn, default=true

Colours tables below are defined into braces :
{position in the gradient (0 to 1), colour in hexadecimal, alpha (0 to 1)}
example for a single colour table : 
{{0,0xFFAA00,1}} position parameter doesn't matter
example for a two-colours table : 
{{0,0xFFAA00,1},{1,0x00AA00,1}} or {{0.5,0xFFAA00,1},{1,0x00AA00,1}}
example for a three-colours table : 
{{0,0xFFAA00,1},{0.5,0xFF0000,1},{1,0x00AA00,1}}

bg_colour1    - colour table for background,
              default = {{0,0x00ffff,0.1},{0.5,0x00FFFF,0.5},{1,0x00FFFF,0.1}}
fg_colour1    - colour table for foreground,
              default = {{0,0x00FF00,0.1},{0.5,0x00FF00,1},{1,0x00FF00,0.1}}
bd_colour1    - colour table for border,
              default = {{0,0xFFFF00,0.5},{0.5,0xFFFF00,1},{1,0xFFFF00,0.5}}              

Seconds tables for radials gradients :
bg_colour2    - second colour table for background, default = no second colour
fg_colour2    - second colour table for foreground, default = no second colour
bd_colour2    - second colour table for border, default = no second colour

draw_me     - if set to false, text is not drawn (default = true or 1)
              it can be used with a conky string, if the string returns 1, the text is drawn :
              example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",

v1.0 (08 Aug. 2010) original release
v1.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"
                    text is parsed inside the function, not in the array of settings

86400 is a magic number, I have some conkys that use that as it's

upate_interval

In fact I was just working on one, my remind calendar. After all, a calendar only updates on a daily basis. It's in a window so I close it when I have see my reminders for the date

Gotta look at that code though, thanks for that.
