--[[ 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"

il y a un truc étrange dans ce script, les zones ou le texte est en gris ne sont pas gérées par le conky mais par des rectangle dessinés par le script lua.
Il faudra certainement supprimer l'une des lignes suivante, et modifier la position de certaines après la modification.

    ---------------------- PARAMETERS BEGIN HERE
    local boxes_settings={
    {x=0,y=50,w=200,h=60, corners={ {"circle",10} },colour={ {0,0x1F1F1F,0.5} },operator="atop" } ,
    {x=0,y=195,w=200,h=60, corners={ {"circle",10} },colour={ {0,0x1F1F1F,0.5} },operator="atop" } ,

a mon avis sa ce joura sur les deux dernières certainement comme ceci, mais je suis pas sure.

l'autre partie n'a aucun effet donc je l'ai remise comme à l'origine

en fait l'autre partie semble éclaircir le texte dans certaines zones en ajoutant une sorte de claque, tu devrais donc te retrouver avec une partie des port ouvert en noir et le reste en gris.

d'accord je regarderai donc cela ce soir de plus près

caymus · Le 06/06/2012, à 10:14

Salut,
En fait la 2eme partie du lua, c' est un 2eme script, de wlourf "box" elles affichent bien des rectangles noir transparant.
Ce que je ne comprends pas, c' est que tu parles de conkyrc_5 et de conky_8.lua
à la base c' etait conky_7b si je me rappel bien.
Si les box noir ne s' affichent pas du tout, malgré qu' elles sont biens presentes dans le lua c' est probable que tu aies oublié:

lua_draw_hook_post main_box

dans le conky.
Enfin sinon je voix pas trop car c' est un peu confu, sur ton image, on dirait que tu utilises conky_7a.lua, et dans ton code pasté sur le forum, c' est conky_7b.lua que tu as renomé conky_8.lua

il y a un truc étrange dans ce script, les zones ou le texte est en gris ne sont pas gérées par le conky mais par des rectangle dessinés par le script lua

Bien en fait si tu parles des 1ere lignes d' info, en gris claire, la couleur est bien geré par le conky:

default_color 666666
color1 888888
color2 AAAAAA
color3 DDDDDD
color4 CC3333

${color2}${top name 1}
${color}${top name 2}
par exemple, et ainsi de suite.

en fait les box n'apparaissent pas a couse de cette argument dans le conky

own_window_argb_visual yes

la fenêtre étant gérée en vrais transparence tous ce qui est dedans est transparent (voir invisible), a mon avis le choix de cette solution tient au fais que de xfce la fausse transparence de conky ne fonctionnait pas jusqu’à la version 4.10

caymus · Le 06/06/2012, à 10:28

Ok, un moment tu m' as fais peur je croyais que j' avais merdé dans mes conkyrc, surtout que je les avaient fait à la chaine, mais j ai bien:
#own_window_argb_visual
dans les originaux.
xfce j' avais pas essayé, j' utilises gnome 3, gnome2 et openbox, pour tester.
Toujours bon à savoir pour xfce, merci de l' info

Excuse moi j'avais pas fait attention tu est l'auteur du conky, en fait il est super actif ce forum, il y a plein de créateur, c'est cool.
Une petite question tu n'a s jamais essayé de rendre tes conky évolutif.
Je m'explique, dans le cas de ljere le eth0 ne sert à rien, certainement car il ne ce sert que du Wifi, dans mon cas ce serait le contraire, et je suppose que dans ton cas tous ne sert pas en même temps, du coups ce serais sympa si ton conky n'affichait que ce qui les infos utile à l’utilisateur.
Si tu as besoins d'aide pour modifier le script lua, je suis là, bien que d'autres pourrais le faire aussi

En fait dans lua ce sera un peut plus compliqué que dans le conkyrc, car nous mettons les infos pour l'affichage dans un tableau, donc pas de code à cette endroit ci, mais sa peut se faire, j'en suis persuadé.
Il faut que je retrouve tes conkys et je regarderais ça.

Edit ; il manque un end_if dans ton conky (toutes condition doit être fermée, la tu utilise deux condition imbriqués l'une dans l’autre, tu doit donc fermer les deux)
Une fois corrigé sa donne sa

@ caymus,
voici le script lua modifié

--[[ 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"

Je me suis contenter d'ajouter une variable contenant un test conky dans le tableau, si le test renvoi Ok alors le bloc de donnés du tableau est traité sinon il est simplement ignoré. (attention ce doit être Ok pas ok, OK où oK).

donc conky nous dit que tu n'as pas de sdc ni de sdb, pour les autres répertoires, je suppose qu'ils existent, mais que la partition les contenants n'est pas monté.

Non ils n'existent pas les clés usb ne sont pas branchées. Ça serait ça le problème?
PS: j'ai édité mon message d'avant pour voir les messages quand ça fonctionne.

en théorie non, c'était juste pour limiter les erreurs, et peut être empêcher le conky de planté suite a un trop grand nombre de problèmes.

Tu peut faire une capture de ton conky.

Bon alors dans mon conky j'ai tenté en supprimant petits bouts par petits bouts après TEXt, mais toujours la même erreur, en supprimant l'intégralité après TEXT il veut bien se lancer (bon ya rien par contre ^^)
Ça se peut qu'il y ait un conflit entre 2 choses affichées?

ce bug devrait affecter tous tes conky, mais en effet sa semble venir de là donc patience sa sera réglé avec une prochaine mise a jour de ubuntu.

bonjour j'ai donc commenté
# own_window_argb_visual yes
ce qui donne ce résultat

si j'ai bien compris je dois donc jouer avec le tableau pour avoir quelque chose de correct
