conky: Run two LUA scripts from one

loutch · 2016-01-10 10:05:22

Hello

I try to make a lua script who launch 2 or more script .lua but he not work

 


package.path = "/home/loutch/.conky/blanc/?.lua"
require 'baro' 
require 'textwriting'

function conky_main()
     lua_draw_hook_pre main()
     lua_draw_hook_post draw_text()
end

and calling in conky with

lua_load ~/.conky/blanc/barotext.lua
lua_draw_hook_pre main

post main not work too ,to remplace this

lua_load ~/.conky/blanc/baro.lua
lua_draw_hook_pre main

lua_load ~/.conky/blanc/textwriting.lua
lua_draw_hook_post draw_text

any idea what i'am wrong

Moved this here as it's not really a Teo bash script problem.

Sorry I can't help you with lua.

loutch , i think i got it ,i am running conky-all 1.10.6-1 try this:

--paths-must-be->/home/worldchampions/.conky/...
--not--> ~/
function conky_main()
dofile ('/home/manuel/conky-conf/Conky_all_Lua/lua/text.lua')
dofile ('/home/manuel/conky-conf/Conky_all_Lua/lua/equalizer.lua')
dofile ('/home/manuel/conky-conf/Conky_all_Lua/lua/draw_bg.lua')

--call of the two mains functions in the lua files
conky_draw_text()
conky_main_bars()
conky_draw_bg()
end

Cheers........

--[[Background originally by londonali1010 (2009)
    ability to set any size for background mrpeachy 2011
    ability to set variables for bg in conkyrc dk75

  the change is that if you set width and/or height to 0
  then it assumes the width and/or height of the conky window

so:

lua_load ~/Conky/LUA/draw_bg.lua
TEXT
${lua conky_draw_bg 20 0 0 0 0 0x000000 0.4}


${lua conky_draw_bg corner_radius x_position y_position width height color alpha}

covers the whole window and will change if you change the minimum_size setting

--[[ BARGRAPH WIDGET
	v2.1 by wlourf (07 Jan. 2011)
	edited by Caymus
	this widget draws a bargraph with different effects 
	http://u-scripts.blogspot.com/2010/07/bargraph-widget.html
	
To call the script in a conky, use, before TEXT
	lua_load /path/to/the/script/bargraph.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:
x,y		- coordinates of the starting point of the bar, default = middle of the conky window
cap		- end of cap line, ossibles values are r,b,s (for round, butt, square), default="b"
		  http://www.cairographics.org/samples/set_line_cap/
angle	- angle of rotation of the bar in degress, default = 0 (i.e. a vertical bar)
		  set to 90 for an horizontal bar
skew_x	- skew bar around x axis, default = 0
skew_y	- skew bar around y axis, default = 0
blocks  - number of blocks to display for a bar (values >0) , default= 10
height	- height of a block, default=10 pixels
width	- width of a block, default=20 pixels
space	- space between 2 blocks, default=2 pixels
angle_bar	- this angle is used to draw a bar on a circular way (ok, this is no more a bar !) default=0
radius		- for cicular bars, internal radius, default=0
			  with radius, parameter width has no more effect.

Colours below are defined into braces {colour in hexadecimal, alpha}
fg_colour	- colour of a block ON, default= {0x00FF00,1}
bg_colour	- colour of a block OFF, default = {0x00FF00,0.5}
alarm		- threshold, values after this threshold will use alarm_colour colour , default=max
alarm_colour - colour of a block greater than alarm, default=fg_colour
smooth		- (true or false), create a gradient from fg_colour to bg_colour, default=false 
mid_colour	- colours to add to gradient, with this syntax {position into the gradient (0 to1), colour hexa, alpha}
			  for example, this table {{0.25,0xff0000,1},{0.5,0x00ff00,1},{0.75,0x0000ff,1}} will add
			  3 colurs to gradient created by fg_colour and alarm_colour, default=no mid_colour
led_effect	- add LED effects to each block, default=no led_effect
			  if smooth=true, led_effect is not used
			  possibles values : "r","a","e" for radial, parallelel, perdendicular to the bar (just try!)
			  led_effect has to be used with theses colours :
fg_led		- middle colour of a block ON, default = fg_colour
bg_led		- middle colour of a block OFF, default = bg_colour
alarm_led	- middle colour of a block > ALARM,  default = alarm_colour

reflection parameters, not avaimable for circular bars
reflection_alpha    - add a reflection effect (values from 0 to 1) default = 0 = no reflection
                      other values = starting opacity
reflection_scale    - scale of the reflection (default = 1 = height of text)
reflection_length   - length of reflection, define where the opacity will be set to zero
					  calues from 0 to 1, default =1
reflection			- position of reflection, relative to a vertical bar, default="b"
					  possibles values are : "b","t","l","r" for bottom, top, left, right
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 (10 Feb. 2010) original release
v1.1 (13 Feb. 2010) numeric values can be passed instead conky stats with parameters name="", arg = numeric_value	
v1.2 (28 Feb. 2010) just renamed the widget to bargraph
v1.3 (03 Mar. 2010) added parameters radius & angle_bar to draw the bar in a circular way
v2.0 (12 Jul. 2010) rewrite script + add reflection effects and parameters are now set into tables
v2.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"

--[[TEXT WIDGET v1.3 by Wlourf 25/06/2010
This widget can drawn texts set in the "text_settings" table with some parameters
http://u-scripts.blogspot.com/2010/06/text-widget.html

The parameters (all optionals) are :
text        - text to display, default = "Conky is good for you"
			  use conky_parse to display conky value ie text=conly_parse("${cpu cpu1}")
            - coordinates below are relative to top left corner of the conky window
x           - x coordinate of first letter (bottom-left), default = center of conky window
y           - y coordinate of first letter (bottom-left), default = center of conky window
h_align		- horizontal alignement of text relative to point (x,y), default="l"
			  available values are "l": left, "c" : center, "r" : right
v_align		- vertical alignment of text relative to point (x,y), default="b"
			  available values "t" : top, "m" : middle, "b" : bottom
font_name   - name of font to use, default = Free Sans
font_size   - size of font to use, default = 14
italic      - display text in italic (true/false), default=false
oblique     - display text in oblique (true/false), default=false (I don' see the difference with italic!)
bold        - display text in bold (true/false), default=false
angle       - rotation of text in degrees, default = 0 (horizontal)
colour      - table of colours for text, default = plain white {{1,0XFFFF00,1}}
			  this table contains one or more tables with format {P,C,A}
              P=position of gradient (0 = beginning of text, 1= end of text)
              C=hexadecimal colour 
              A=alpha (opacity) of color (0=invisible,1=opacity 100%)
              Examples :
              for a plain color {{1,0x00FF00,0.5}}
              for a gradient with two colours {{0,0x00FF00,0.5},{1,0x000033,1}}
              or {{0.5,0x00FF00,1},{1,0x000033,1}} -with this one, gradient will start in the middle of the text
              for a gradient with three colours {{0,0x00FF00,0.5},{0.5,0x000033,1},{1,0x440033,1}}
			  and so on ...
orientation	- in case of gradient, "orientation" defines the starting point of the gradient, default="ww"
			  there are 8 available starting points : "nw","nn","ne","ee","se","ss","sw","ww"
			  (n for north, w for west ...)
			  theses 8 points are the 4 corners + the 4 middles of text's outline
			  so a gradient "nn" will go from "nn" to "ss" (top to bottom, parallele to text)
			  a gradient "nw" will go from "nw" to "se" (left-top corner to right-bottom corner)
radial		- define a radial gradient (if present at the same time as "orientation", "orientation" will have no effect)
			  this parameter is a table with 6 numbers : {xa,ya,ra,xb,yb,rb}
			  they define two circle for the gradient :
			  xa, ya, xb and yb are relative to x and y values above
reflection_alpha    - add a reflection effect (values from 0 to 1) default = 0 = no reflection
                      other values = starting opacity
reflection_scale    - scale of the reflection (default = 1 = height of text)
reflection_length   - length of reflection, define where the opacity will be set to zero
					  calues from 0 to 1, default =1
skew_x,skew_y    - skew text around x or y axis
			  

Needs conky 1.8.0

You can make a package and launch the conky_draw_bg function from there, something like this:

launcher2.lua

--paths-must-be->/home/worldchampions/.conky/...
--not--> ~/
package.path = '/home/manuel/conky-conf/Conky_all_Lua/?.lua'
require 'draw_bg'
require 'text'
require 'time'
require 'equalizer'

function conky_main()    
    conky_draw_bg(10, 30, 5, 241, 80, 0x000000, 0.4)
    conky_draw_bg(10, 30, 90, 241, 95, 0x000000, 0.4)
end

and from launcher2 delete the line

lua_draw_hook_post = 'draw_bg 20 0 0 0 0 0x000000 0.4',

manuel-909 · 2018-02-06 21:56:02

Thank you indian for your reply..
I will try the launcher... :-)
Did you now how to fix the draw_bg error?

manuel-909 · 2018-02-06 22:29:52

indian i try the launcher code with no luck it won't run the conkyrc..
any ideas?

Indian · 2018-02-07 11:07:28

Do you have all the lua scripts in this folder /home/manuel/conky-conf/Conky_all_Lua/ ?
Have you deleted line lua_draw_hook_post = 'draw_bg 20 0 0 0 0 0x000000 0.4', from the conkyrc file?
How do you launch conky?

I have modified the launcher to get the time script working

end

And in the conkyrc the i have also modified the first line in conky.text

${color3}${offset 10}${font Justice:size=22:Bold}${lua Hour_Main}${lua Minute_Main}

And i get something similar to the example1 image you have posted.

It works, using conky_draw_bg(10, 30, 5, 241, 80, 0x000000, 0.4) get background one size,
and using lua_draw_hook_post = 'draw_bg 20 0 0 0 0 0x000000 0.4', inside conky backround change with the text size..
Thank you indian..

^That's really cool, especially that weather and moon panel!

^ @Indian, @manuel-909

Okay, very nice! An excellent job.
Thus we have in Conky1.10 with "the help" of the Lua-Script
draw_bg.lua again the "round corners" and a background to be modified accordingly. Right? ]:D

Sector11 would say now, which one of you puts this in a sticky here in the forum, so that everyone gets something out of it? Because the theme of this thread does not express it...

My personal opinion is (without diminishing your work!), also in the future the user will have his trouble with the syntax of version 1.10. There's no way around it!

You guys are tops! O:)

i find a conky conf really nice have a loadall.lua that work's nice you have to make a foler for what you wan't to run.....

autostart-All.sh

#!/bin/sh
# You can use this script to create an autostart,it will cd into the theme folder before executing conky
# Conkies can be started individually through terminal from their directory (conky -c conky.conf or cd /path/to/theme/ && conky -c conky.conf)

killall conky

        # Making sure theme-dir is working-dir
        cd "$(dirname "$0")"

# start system conky
 sh conky-system-lua-V3/autostart.sh
    sleep 1
# start clock conky
 sh conky-clock-lua-V1/autostart.sh
sleep 1
# start  cores conky
 sh conky-cores-lua/autostart.sh
sleep 1
# start  vnstat conky
 sh conky-vnstat-lua/autostart.sh
sleep 10
# start  vnstat conky
 sh conky-weather-lua/autostart.sh


exit

autostart.sh

    #killall conky

        # Making sure theme-dir is working-dir
        cd "$(dirname "$0")"

    ( set -x; setsid conky -c cores.conf )

exit
