--[[ RINGS with SECTORS widget
    v1.0 by wlourf (08.08.2010)
    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

--[[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 {{1,0xFFFFFF,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
              

Needs conky 1.8.0

Bon pour changer les couleurs, à part du rechercher/remplacer + modif de l' image d'arrière plan, ça risque d'être un peu long :-D

Bon du coup j'ai réussi à modifier un peu les script de texte courbé, seulement le rendu n'est pas au rendez-vous, ça ne me plait pas trop. Je garderai donc cette version :


Quand il me restera un peu de temps libre, je ferai une même version mais avec les bleus officiels de Fedora

Comme prévu, la dernière mise à jour de ce conky. Au taf, ça donne ça avec le wallpaper de F14 (mais sous F12...)

La petite nouveauté, j'ai rajouté deux variables (gap_conky_x et y) pour spécifier le décalage de la fenêtre conky (histoire que, si vous voulez décaler votre conky, vous ayez que deux variables à changer. C'est mieux que se retaper toutes les coordonnées pour tous les éléments).

J'ai également changé de police pour la typo LCD : DS-Digital (dispo sur DaFont). Ce qui fait juste StyleBats et DS-Digital à installer.

Pour ceux qui veulent approfondir les scripts originaux, faites un tour sur le site du développer du script, y a pleins d'exemples (je viens même de découvrir l'histoire des bordures d'anneaux :-P )

J'ai commencé un conky avec le logo Ubuntu, mais je manque cruellement d'inspiration... Donc ça va très probablement passer à la trappe... 🙂
