Previously the code was assuming the windows were placed at 0,0. This might not
be the case and the window X and Y values should be used when trying to
position items relative to a window.
This change needs to be applied to all other scripts otherwise mutiple screen
setups may have unaligned elements. Updates scripts should be tested using
multi-head test systems or the x11 test renderer.
Enables scripts to display test by converting it into an image. This can then
be shown using a sprite. Function takes a string and the value of the three
colors (red green blue).
new_image = Image.Text("text we want", 1.0, 0.0, 0.0); // gives red text image
The callback is called before the final sprite refresh and quit. This allows
the theme to tidy up the screen before handing over to the X fade and the
destop manager.
Removes the spinfinity function as it used an ugly ../ path to get the images
and assumed that spinfinity was installed.
Removes some elements which were only inserted for testing.
Two functions set the color of either the bottom or the top of the screen. If
the two colors are equal a solid colour draw is used. The color is supplied by
three floats specitying red green and blue elements.
The example script now can show a spinfinity or a fade_in behaviour. This is
just to see how easy it is to implement current plugins. In the case of fade_in
it is around 23 lines of script code
Matches the use in C as "for (first, condition, last)" where first is executed
once, last is executed at the end of each iteration (even when continue is
executed) and condition is tested at the start of every cycle.
The scripts can now attach themselves to the following callbacks: refresh,
boot_progress, root_mounted, keyboard_input, update_status, display_normal,
display_password and display_question.
Treats "/*" and "*/" as block comment markers. Block comments may be nested.
There is a bug where if a comment or a string is not terminated before the end
of a file, the scanner deadlocks. Need to add a way or reporting scanner
errors to the parser.
These are currently hard coded to '//' and '#'. The code is there to return
them to the caller but currently they are thrown away.
Should add a skip_comments option and allow customisable markers.
An image rotate operation creates a new image with the same dimensions but with
the contents rotated by an angle around the centre of the image. Also added a
script object to float function to allow this.
Allows execution of unary operations: Pre/postfix inc/decrement, logical
negation and unary plus/minus.
The writebacks of increment/decrements happen during the execution of the
expression, unlike C where they are executed after the line if executed. This
is the case simply because it is simpler to execute this way.
This is an initial support for the scripted plugin. There are _many_ FIXMEs
and the whole code is reather unstable. The formatting is completely incorrect
and will be changed soon. There are scripts which are converted using a perl
to an C embeddable string.
