Overview of new features in Calcpad

Hello, guys!

A brief overview of the recent changes in Calcpad was published in our blog.

Also, I started to make a simple macro language for easy SVG drawings of cross sections. It is used for the example from the screenshot in the blog (svg.txt). It includes commands for drawing lines, circles, texts and dimensions. Bellow is the source code of what I have done so far:

#def line$(x1$; y1$; x2$; y2$; style$) = '<line x1="'x1$'" y1="'y1$'" x2="'x2$'" y2="'y2$'" style$/>
#def circle$(x$; y$; style$) = '<circle cx="'x$'" cy="'y$'" r="15" style$/>
#def texth$(x$; y$; s$) = '<text x="'x$'" y="'y$'" text-anchor="middle">s$</text>
#def textv$(x$; y$; s$) = '<text x="'x$'" y="'y$'" text-anchor="middle" transform="rotate(-90,'x$','y$')">s$</text>
#def sec_style$ = style="stroke:black; stroke-width:12; fill:lightyellow"
#def axis_style$ = stroke-dasharray="60,15,10,15" style="stroke:#AAFF88; stroke-width:8"
#def dim_style$ = style="stroke:goldenrod; stroke-width:4; fill:goldenrod"
#def red_style$ = style="stroke:red; stroke-width:6; fill:red"
#def dimh$(x1$; x2$; y$; s$)
	line$(x1$; y$ - 50; x1$; y$ + 50; dim_style$)
	line$(x2$; y$ - 50; x2$; y$ + 50; dim_style$)
	line$(x1$ - 50; y$; x2$ + 50; y$; dim_style$)
	circle$(x2$; y$; dim_style$)
	circle$(x1$; y$; dim_style$)
	texth$((x1$ + x2$)/2; y$ - 30; s$)
#end def
#def dimv$(x$; y1$; y2$; s$)
	line$(x$ - 50; y1$; x$ + 50; y1$; dim_style$)
	line$(x$ - 50; y2$; x$ + 50; y2$; dim_style$)
	line$(x$; y1$ - 50; x$; y2$ + 50; dim_style$)
	circle$(x$; y1$; dim_style$)
	circle$(x$; y2$; dim_style$)
	textv$(x$ - 30; (y1$ + y2$)/2; s$)
#end def

BTW, you may notice that my version is 5.9.3. I have a few more minor bugs to fix and I will release it. I also want to implement some of the recent suggestions: #96 , #110 , etc. before that. :)
