Bon comme je suis impatient ^^ j'ai activé le dépot precise-backports
Comme c'était la même version du paquet, j'ai été chercher là, et j'ai installé ça: http://packages.ubuntu.com/fr/precise-backports/conky
Et comme ça fonctionnait toujours pas j'ai pris ça: http://packages.ubuntu.com/quantal/conky-all
Et là ça fonctionne
Je sais c'est bancal comme solution mais au moins plus de problème

Merci pour ton aide !

Ce serait pas le rc du conky de gauche ??
C'est que j'aime beaucoup les couleurs des barres d'infos, dans le conky à droite sur l'image

Oups c'est bon, j'avais pas vu que tu venais juste de le poster plus haut.
Merci les gars, voici ce que j'obtiens après légères modifications de dimensionnements et de fond, couleurs etc.
écran 1920x1080. L'ancien et le nouveau conky Le conky_8.lua et conky 19rc disponibles.
L'un travaillant avec l'autre. Le conky19rc utilise le lua du conky_8.lua pour les barres colorées. Donc faire bien attention à l'adressage de chaque élément, pour qu'ils se trouvent correctement. j'ai rajouté aussi le Calendrier, Clémentine et UpTime.
Pour l'ancien conky tout bete ici le fichier

caymus · Le 07/06/2012, à 00:52

@ Didier-T
Un tres grand merci à toi pour avoir modifié le lua, je testerai cela demain, et j' etudierai tes modifications pour comprendre comment cela fonctionne.
Je suis un peu entre 2 chaises pour le moment, je fais un tuto sur un HP dl380 g5 et vmware esxi, xen.
Je reviendrai surement avec des questions sur les lua ^^, car j' ai fini le music player interactif dans conky, pour audacious, mais j' ai encore 2-3 choses à regarder, comme rajouter le bitrate et comprendre pourquoi les boutons ne changent pas de couleur quand on clic dessus, ou seulement une fois sur 20.

@ljere

dans le lua tu peux effacer si tu veux: operator="atop"

par exemple
{x=0,y=529,w=200,h=25, corners={ {"circle",10} },colour={ {0,0x1F1F1F,0.5} },operator="atop" } ,
devient
{x=0,y=529,w=200,h=25, corners={ {"circle",10} },colour={ {0,0x1F1F1F,0.5} } } ,

atop ne sert à rien dans ce cas ci, c' etait un test de ma part et j ai oublié de le retirer, il sert quand par exemple 2 fenetres cairo transparantes, de couleur differente se chevauche, pour donner un effet, la 1ere fenetre est affichée, la 2 eme n' est affichée que sur la partie qui chevauche la 1ere.

CAIRO_OPERATOR_ATOP
This leaves the first object mostly intact, but mixes both objects in the overlapping area. The second object object is not drawn except there.
If you look closely, you will notice that the resulting color in the overlapping area is different from what the OVER operator produces. Any two operators produce different output in the overlapping area!
The output of the ATOP operator is the same for both bounded and unbounded source.
Resulting alpha (aR) Resulting color (xR)
aB xaA + xB·(1−aA)

http://cairographics.org/operators/

@ enebre
pour donner un effet "italique" aux barres j' ai rajouté:
cap="e"
dans le lua
si tu retires cela, tu redresses les barres, au cas ou tu en aurais envie.
Et aussi:
fg_colour={0x00ff00,1}, (couleur de depart)
mid_colour={{0.5,0xffff00,1}} (couleur intermediaire)
alarm_colour={0xff0000,1}, (couleur de fin)
alarm=80, (quand la couleur de fin apparait en %)
smooth=true, (pour faire une transition "douce" entre les 3 couleurs)

pour les couleurs c' est en hexadecimal, tu trouve la valeur hexa avec gimp ou sur un site web de ce genre: http://www.colorschemer.com/online.html

à et derniere petite chose, par exemple:
fg_colour={0x00ff00,1},

le 1 en rouge c' est la valeur alpha (la transparence) de 0 a 1 0 totalement transparent, 1 totalement opaque.
exemple: fg_colour={0x00ff00,0.4},

merci c'est parfait

rpj · Le 07/06/2012, à 09:52

Tu peut aussi faire des dégradés (dans un cercle ou un graph par ex):

    bg_colour1={{0,0xa8cdcc,1}},
    fg_colour1={{0,0xd58484,0.7},{0.5,0xd58484,0.5},{1,0xfff667,0.7}}, --[[ couleur mesure min--]]
    fg_colour2={{0,0xe36704,0.7},{0.5,0xe36704,1.0},{1,0xfff667,0.7}}, --[[couleur mesure max--]]
    },

@ Didier

C' est bien cette partie la que tu as ajouter?

 if bars_settings[i].exist==nil then bars_settings[i].exist="" end
            if bars_settings[i].exist~="" then 
                if conky_parse(bars_settings[i].exist)==Ok then
                       draw_multi_bar_graph(bars_settings[i])
                  end

Oubien j' ai loupé d' autres modification du code plus loin dans le script?
En tout cas un grand merci à toi,
PS: si je devais faire la meme chose pour le script "box" que j ai copié dans le meme lua en dessous du 1er script "rings", cela serait la meme methode à appliquer?
Je me doute que oui, mais dans le doute je prefere te demander

local boxes_settings=

donnerait pour la 2eme partie:

 if boxes_settings[i].exist==nil then boxes_settings[i].exist="" end
            if boxes_settings[i].exist~="" then 
                if conky_parse(boxes_settings[i].exist)==Ok then
                       draw_box(boxes_settings[i])
                  end

ici dedans?

if tonumber(conky_parse("$updates"))<5 then return end
    for i in pairs(boxes_settings) do
        draw_box (cr,boxes_settings[i])

Autre question, car je suis nul en progr, le Ok devra etre changer par ok dans le 2eme script pour eviter les conflits oubien cela ne posera pas de problems?

Bonjour caymus,

Il faut faire attention a deux choses :
la première dans lua tous texte non entouré de " est considéré comme une variable.
la seconde comme dans conky tous test doit avoir une fin donc autant de end que de if.

Sinon j'ai l’impression que tu a bien compris les modifications apporté au script (n'oublie pas d'ajouté exist dans le tableau boxes_settings et de fermer chaque ligne par une virgule)

Pour le "Ok" sa n'a pas d'importance, car il s'agit du résultat du test effectué par conky.

Encore une fois meric à toi Didier-T, pour ta disponibilitée et tes conseils avisés.
Quand j aurai fini la modification du 2eme script, je mettrai à jour les conky sur gnome-look.
Sans toi, il ne m' aurait pas ete possible de faire cela dans le lua, car j' etais vraiment loin de la bonne solution.

caymus · Le 08/06/2012, à 15:23

Re Didier,
C' est encore moi, excuse moi de te déranger j ai un truc qui me chiffone, je voudrais tes conseils eclairés la dessus:

box:

function conky_main_box()

    if conky_window==nil then return end

    ---------------------- PARAMETERS BEGIN HERE
    local boxes_settings={
    --FIRST COLUMN
        --default colour and corner

    }


    ---------------------------- PARAMETERS END HERE
    
    local cs=cairo_xlib_surface_create(conky_window.display, conky_window.drawable, conky_window.visual, conky_window.width, conky_window.height)
    local cr=cairo_create(cs)
    
    if tonumber(conky_parse("$updates"))<5 then return end
    for i in pairs(boxes_settings) do
        if boxes_settings[i].exist==nil then boxes_settings[i].exist="" end
        if boxes_settings[i].exist~="" then 
        if conky_parse(boxes_settings[i].exist)=="Ok" then
                       draw_box(boxes_settings[i])
                  end
              else
        draw_box (cr,boxes_settings[i])
    end
    end
    cairo_destroy(cr)
    cairo_surface_destroy(cs)    
end

Pourquoi ici je dois mettre 2 end en dessous de draw_box si non j' ai une erreur nil

alors que ici:

rings:

    if conky_window==nil then return end

    local cs=cairo_xlib_surface_create(conky_window.display,
        conky_window.drawable, 
        conky_window.visual, conky_window.width, conky_window.height)
    local cr=cairo_create(cs)

    if tonumber(conky_parse('${updates}'))>3 then
        for i in pairs(rings_settings) do
        if rings_settings[i].exist==nil then rings_settings[i].exist="" end
        if rings_settings[i].exist~="" then 
        if conky_parse(rings_settings[i].exist)=="Ok" then
                       draw_ring(rings_settings[i])
                  end
              else


            draw_ring(cr,rings_settings[i])
        end
        end
        end

    cairo_destroy(cr)

end

Je dois en mettre 3 en dessous de draw_ring
J arrive pas à compter

Didier-T · Le 08/06/2012, à 16:49

@ caymus,
Pour rendre ton code plus lisible et éviter les erreurs, je te propose de faire ceci.

quand tu commence une boucle ou un test tous ce que tu met a l'intérieur tu y ajoute une tabulation.

Par Exemple :

if "test"
  if "test2"
    action si Ok
  else
    action si pas Ok
  end
else
  action si pas Ok
end

Comme sa ton code te parle visuellement

enebre · Le 08/06/2012, à 17:51

http://blacknegative.com/ +-la 7ème page "SANOFI"
Si ce style de page pouvait être adaptée dans lua en mode dynamique ce serait waouh !
les rings suivent la souris, c'est ouf ça !

Dès que ça bouge, ça évolue... donc pourvu que ça puisse bouger. Car alors viendra la révolution du système. "et le Tube !" Nous sommes sur une wave içi, ça surf et ça roxxe. Je ne sais pas pour vous mais pour moi rien que de participer à votre forum, je la sent qui monte... la vague. Ceux qui ont fait du surf, body-surf, voile, vole-à-voile, savent bien ce que je veux dire. Il me semble que l'avenir de la commande-interface-homme-machine passera par cette voie. Car le clic de l'icône ne me semble pas assez élaboré pour rejoindre la nécessaire complexité de l'interface, capable de satisfaire longtemps les besoins de l'esprit humain, dans sa relation avec cette machine... qui mérite mieux que le clic et l'icône. Et comme l'écran semble s'orienter pour être un support transparent... Nous sommes ici au delà de l'icône et du clic, ou comment dire .. déjà ..+.. à l'intérieur de la machine. Un peu plus avancé sur l'onde. Non j'ai rien fumé, la moquette est intacte.

comme tu peut le constater c'est bien plus simple comme sa pour voir a qui appartient le end

Re Didier-T,

Le script marche tres bien pour les "Bars" script, J' ai pas encore essayé pour les "Boxs" script, et pour les "Rings" script je bute sur une erreur:

--[[ RINGS with SECTORS widget
    v1.1 by wlourf (07 Jan. 2011)
    edited by Caymus
    add new function by Didier-T
    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
v1.2 (09 Jun. 2012) Add exist parameter, tanks to "Didier-T"

ligne 434:if t.draw_me == true then t.draw_me = nil end
ligne 435:if t.draw_me ~= nil and conky_parse(tostring(t.draw_me)) ~= "1" then return end

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",

Je ne vois pas trop quoi faire non plus sur ce coup la.

PS:J ai mis ton pseudo dans les scripts car c' est toi qui as tout fait pour finir , si cela ne te dérange pas bien sur? Si non je le retirai.

@ caymus,
Ton soucis vient de la ligne n°284, il manque la variable cr à ton appelle à draw_ring

Voici la ligne corrigée

draw_ring(cr,rings_settings[i])

Pour la présence de mon pseudo, pas de soucis sa ne me dérange pas.
Par contre ce serait intéressant d'indiquer le nom du forum.

--[[ RINGS with SECTORS widget
    v1.1 by wlourf (07 Jan. 2011)
    edited by Caymus
    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
