Re : (4) Conky : Postez vos conkyrc ou certaines parties intéressantes
je crois que c'est sh le problème. lance avec bash ou en rendant le script exécutable et en le lançant via :
./test2.sh
OU
bash test2.shPour ton code, le probleme vient du calcul. l'interpreteur ne sait pas calculer des nombres décimaux par défaut. il faut utiliser "bc".

@levi59: merci... ton script marche au poil...maintenant il va falloir représenter ça sur l’écran...

Re : (4) Conky : Postez vos conkyrc ou certaines parties intéressantes
pour la partie lua j'ai jamais fait. Par contre je crois qu'il y a un sujet conky pour lua sur le forum... @ voir.

Re : (4) Conky : Postez vos conkyrc ou certaines parties intéressantes
@levi59: j'ai légèrement adapté ton script en remplaçant FRXX1949 par $1 afin de l’exécuter avec comme paramètre la localisation...ça sera plus pratique pour la suite.
j'ai fait des tests avec 20 valeurs dans le fichier. en prenant des mesures toutes les 4hrs, ca donnerait un historique de 3 jours pour ceux dont la machine tourne en continu...
(je ne sais pas encore combien de valeurs seront nécessaires pour avoir un affichage correct et relevant, toutes les idées sont les bienvenues [relevé toutes les heures, toutes les 4Hrs, 12Hrs, 1xpar jour...])
je me plonge dans le lua pour essayer d'afficher qqch....mais ici aussi un expert serait le bienvenu...
j'ai bidouillé un graphe en juxtaposant 20 colonnes (sur base du script bargraph de wlourf)et ça donne ceci...
bargraphpression.lua
--[[ BARGRAPH WIDGET
v2.1 by wlourf (07 Jan. 2011)
this widget draws a bargraph with different effects
http://u-scripts.blogspot.com/2010/07/bargraph-widget.html
To call the script in a conky, use, before TEXT
lua_load /path/to/the/script/bargraph.lua
lua_draw_hook_pre main_rings
and add one line (blank or not) after TEXT
Parameters are :
3 parameters are mandatory
name - the name of the conky variable to display, for example for {$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"

Bonjour à tous...
Grâce au script bash de levi59 et aux scripts lua de wlourf,

--[[ BARGRAPH WIDGET
v2.1 by wlourf (07 Jan. 2011)
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 v1.42 by Wlourf 07 Feb. 2011
This widget can drawn texts set in the "text_settings" table with some parameters
http://u-scripts.blogspot.com/2010/06/text-widget.html
To call the script in a conky, use, before TEXT
lua_load /path/to/the/script/graph.lua
lua_draw_hook_pre main_graph
and add one line (blank or not) after TEXT
The parameters (all optionals) are :
text - text to display, default = "Conky is good for you"
it can be used with conky variables, i.e. text="my cpu1 is ${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 {{1,0xFFFFFF,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
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 07/06/2010, Original release
v1.1 10/06/2010 Add "orientation" parameter
v1.2 15/06/2010 Add "h_align", "v_align" and "radial" parameters
v1.3 25/06/2010 Add "reflection_alpha", "reflection_length", "reflection_scale",
"skew_x" et "skew_y"
v1.4 07/01/2011 Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"
text is parsed inside the function, not in the array of settings
v1.41 26/01/2011 Correct bug for h_align="c"
v1.42 09/02/2011 Correct bug for orientation="ee"

ce n'est certainement pas la méthode la plus économique en ressources ni en nombre de lignes de code, donc si un expert en lua veut faire quelque chose de moins gourmand, ça serait pas mal...

Re : (4) Conky : Postez vos conkyrc ou certaines parties intéressantes
C'est beau 
J'ai dans l'idée de faire la même chose avec un script qui me récupère es T°, utilisation CPU et RAM un peu dans le genre Mumin mais avec un vrai archivage, il faut peut-être que je me tourne vers ça.
Bravo en tout cas.

Re : (4) Conky : Postez vos conkyrc ou certaines parties intéressantes
Bonjour à tous!
J'essaye d'utiliser le script de shamen456 (#907) avec le script lua associé.
Ceci dit je tombe sur ce message d'erreur:
Conky: llua_do_call: function conky_main execution failed: /home/xavier/.conky/.arcs_blue.lua:402: attempt to perform arithmetic on local 'value' (a nil value)
La ligne correspondante dans le fichier lua est:
local val = value % (max_value + 1)Je n'arrive pas à comprendre le sens de cette ligne ni ce qui déconne...
Est-ce que quelqu'un peut m'aider svp?

Re : (4) Conky : Postez vos conkyrc ou certaines parties intéressantes
@mutav : c'est bizarre, j'ai jamais eut cette erreur en adaptant le script...
essaie en plaçant ce code sur la ligne juste avant
if value==nil then value=0 endsi j’interprète bien ce qu'il te dit, c'est qu'il essaie de calculer qqch avec value=nil (une valeur texte) au lieu de value=0 (valeur chiffrée)...que les spécialistes en programmation me corrigent si je dis des conneries...
...l'apprentissage par essais et erreurs a ses limites..

Re : (4) Conky : Postez vos conkyrc ou certaines parties intéressantes
remoi sur le baromètre! Je voudrais demander l'aide de ceux qui affichent les donnée de pression pour tester l'utilisation de gnuplot.
C'est la première fois que j'utilise ce logiciel donc je ne suis pas encore super au point mais bon...
J'aimerais que la partie gnuplot soit corrigé au besoin.
Voici la version que je propose (j'ai repris mon ancien script) :
le script se lance avec le code de la ville en argument et créé un fichier log des pressions dans lequel se trouve la date (depuis epoch) et la valeur relevée (-1005 pour mettre l'axe x sur 1005) ainsi qu'un fichier graph.png représentant le graphique des données.
Il suffit alors d'afficher l'image dans conky! 
Confere plus bas! ^^Merci de me donner un retour!

Re : (4) Conky : Postez vos conkyrc ou certaines parties intéressantes
Petite mise à jour du code...
Comme le graphique tiens compte des dates, j'ai modifié le début du script pour qu'il vérifie les dates du fichier log et supprime les valeurs âgées de plus d'une semaine. Ça permet de mieux gérer l'affichage.
Le fonctionnement reste le même que pour la version précédente. (@shamen456 les emplacements des fichiers sont au début du script)
#!/bin/bash
## files
LOG="$HOME/.conky/ListePression.log"
GRAPH="$HOME/.conky/graph.png"
## Vérifier argument
[[ -z $1 ]] && {
echo "Absence d'argument: mettre le code de la ville en argument"; exit 1
}
##Infos générales
DATE=$(date +"%s")
DATE1WEEK=$(date --date="1 week ago" +"%s")
# liste des dates de relevé du fichier log
EPOCH=()
while read
do
EPOCH+=( "$REPLY" )
done< <(awk '{print $1}' "$LOG")
# si le fichier existe et contient des valeurs de plus d'une semaine (première = plus vieille)
#supprimer première valeur
[[ -f $LOG ]] && {
for i in $(seq 0 $(($(wc -l < $LOG)-1)))
do
[[ $DATE1WEEK -gt ${EPOCH[$i]} ]] && sed -i '1d' $LOG || break
done
}
## Récupération de la pression sur weather.com

--[[PIE CHART WIDGET by Wlourf v1.3 07 Jan. 2011
This widget draw a pie chart or a ring in a conky window.
More info on the parameters with pictures on this page :
http://u-scripts.blogspot.com/2010/04/pie-chart-widget.html
To call the script in a conky, use, before TEXT
lua_load /path/to/the/script/piechart.lua
lua_draw_hook_pre main_rings
and add one line (blank or not) after TEXT
Parameters are :
tableV -- table of labels and values {{label,conky_variable,conky_argument,convert to Go-Mo-Ko units (true/false) or unit}, ...}
-- this table is mandatory, others parameters are optionals
-- example :
tableV={
{"cpu 0","cpu","cpu0",100,"%"},
{"cpu 1","cpu","cpu1",100,"%"},
},
-- to know disk space, use this line :
tableV=read_df(false,true),
1st argument : show _media
2nd argument : sort output array
xc -- x center of the pie, default = conky_window.width/2
yc, -- y center of the pie, default = conky_window.height/2
radius_int -- internal radius in pixel, default = conky_window.width/6
radius_ext -- external radius in pixel, default = conky_window.width/4
first_angle -- first angle of the pie (in degrees), default=0
last_angle -- last angle of the pie (in degrees), default=360
type_arc, -- fill the arc in a linear way (ring) or radial way (pie), values l or r, default=l
inverse_l_arc -- inverse arc for rings (true/false), default=false
proportional -- display proportional sectors (true/false); default =false
gradient_effect -- gradient effect (true/false), default=true
line_length -- length for horizontal line (from radius_ext to end of line), default=radius_ext
line_thickness -- thickness of line, default=1
line_space -- vertical space between two lines, default=10 pixels
extend_line -- grow up the line (true/false) if length of text> line_length, default=true
nb_decimals -- number of decimals for numbers, default=1
show_text -- display text (true/false), default=true
font_name -- font, default "Japan"
font_size -- font size, default=12
font_color -- font color (for gradient) or nil (for constant color), default = nil
font_alpha -- font alpha, default=1
txt_offset -- space between text and line, default=1
txt_format -- string for formatting text, possibles values are : default = "&l : &v"
-- &l for label
-- &o for occupied percentage
-- &f for free percentage
-- &v for value
-- &n for free value (non-occupied)
-- &m for max value
-- &p for percentage value of full graph
tablebg -- table of tables of colours for background {colors,alpha}
tablefg -- table of tables of colours for foreground {colors,alpha}
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 10/04/2010 original release
v1.1 15/05/2010 the parameters are in a table (pie_settings), only the values in pie_settings.tableV are mandatory
added an option to draw values like a ring (type_arc="l")
v1.2 26/05/2010 add inverse_l parameter (for type_arc="l")
bug fix : line_length problem
read_df function improved
v1.21 26/06/2010 rename some parameters and write more infos
v1.3 07/01/2011 Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"

--[[ BARGRAPH WIDGET
v2.1 by wlourf (07 Jan. 2011)
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"

--[[PIE CHART WIDGET by Wlourf v1.3 07 Jan. 2011
This widget draw a pie chart or a ring in a conky window.
More info on the parameters with pictures on this page :
http://u-scripts.blogspot.com/2010/04/pie-chart-widget.html
To call the script in a conky, use, before TEXT
lua_load /path/to/the/script/piechart.lua
lua_draw_hook_pre main_rings
and add one line (blank or not) after TEXT
Parameters are :
tableV -- table of labels and values {{label,conky_variable,conky_argument,convert to Go-Mo-Ko units (true/false) or unit}, ...}
-- this table is mandatory, others parameters are optionals
-- example :
tableV={
{"cpu 0","cpu","cpu0",100,"%"},
{"cpu 1","cpu","cpu1",100,"%"},
},
-- to know disk space, use this line :
tableV=read_df(false,true),
1st argument : show _media
2nd argument : sort output array
xc -- x center of the pie, default = conky_window.width/2
yc, -- y center of the pie, default = conky_window.height/2
radius_int -- internal radius in pixel, default = conky_window.width/6
radius_ext -- external radius in pixel, default = conky_window.width/4
first_angle -- first angle of the pie (in degrees), default=0
last_angle -- last angle of the pie (in degrees), default=360
type_arc, -- fill the arc in a linear way (ring) or radial way (pie), values l or r, default=l
inverse_l_arc -- inverse arc for rings (true/false), default=false
proportional -- display proportional sectors (true/false); default =false
gradient_effect -- gradient effect (true/false), default=true
line_length -- length for horizontal line (from radius_ext to end of line), default=radius_ext
line_thickness -- thickness of line, default=1
line_space -- vertical space between two lines, default=10 pixels
extend_line -- grow up the line (true/false) if length of text> line_length, default=true
nb_decimals -- number of decimals for numbers, default=1
show_text -- display text (true/false), default=true
font_name -- font, default "Japan"
font_size -- font size, default=12
font_color -- font color (for gradient) or nil (for constant color), default = nil
font_alpha -- font alpha, default=1
txt_offset -- space between text and line, default=1
txt_format -- string for formatting text, possibles values are : default = "&l : &v"
-- &l for label
-- &o for occupied percentage
-- &f for free percentage
-- &v for value
-- &n for free value (non-occupied)
-- &m for max value
-- &p for percentage value of full graph
tablebg -- table of tables of colours for background {colors,alpha}
tablefg -- table of tables of colours for foreground {colors,alpha}
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 10/04/2010 original release
v1.1 15/05/2010 the parameters are in a table (pie_settings), only the values in pie_settings.tableV are mandatory
added an option to draw values like a ring (type_arc="l")
v1.2 26/05/2010 add inverse_l parameter (for type_arc="l")
bug fix : line_length problem
read_df function improved
v1.21 26/06/2010 rename some parameters and write more infos
v1.3 07/01/2011 Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"
