Happy New Year to all dear fellow OpenSCADists! To enjoy our journey of
OpenSCAD in the new 2016 to come, allow me to present a present: an OpenSCAD
syntax lexer for the editor  SynWrite http://www.uvviewsoft.com/synwrite/
.

It's a lexer intended to deal with large and/or complicated scad files.
Users will be able to divide large code into sections, in-function sections
and in-module sections, all are blocks that can be folded and easily
navigated through the syntax tree panel.

The lexer already being incorporated into the SynWrite library, so you can
get right to it once the SynWrite is installed. Couple of screenshots :

1. The synwrite_syntax_demo.scad domonstrating all the features of the
lexer:

To load it to your SynWrite, just go to [Options]/ [Add-ons Manager] /
[Install]

To use it, select it in the status bar on the bottom of editor.

The demonstrating file, synwrite_syntax_demo.scad, can be downloaded from

sounds and looks pretty good. I'm a notepad++ person and I find the openSCAD
support very good.

How does it compare - anyone know ?

@Neon22, I'm a Notepad++ person, too, being using it for as long as I can
remember.

Ever since I started learning OpenScad, I tried to make it work several
times but has no luck. Later on I found people seem to have done it, so I
picked up and tried those (including yours). What I found is that npp only
provides some commonly used features and I've tried and failed to add stuff
that I want. For example, the different sections type of blocks that I
described in this threads. The flexibility of syntax customization is far
beyond that of SynWrite.

Another consideration is the auto-completion and function parameter hint.
People WERE using Npp for that, but it seems that new version of npp doesn't
allow it anymore.

I am also eyeing at the several other customizations that I mentioned. It
gives me an impression that we can do a lot more to fit out needs.

It doesn't mean that npp is not good tool for OpenSCAD. I think it is still
good for many. But to deal with large and complicated files, which I often
have, npp is just not enough.

Hello,

Tnx runsun for the lexer.
It seems to exist a problem with some rules because some modules do not
appear in the tree list.
A construct like this:

module foo() color("SlateGray") render(convexity=2) // or other any
"operator" before the curly bracket
{
...
}

doesn't appear in the tree list.

Btw, is there a reason for the boolean operators to have the same style as
operators like translation and rotation?
I already defined a new style for the boolean by editing directly the file
Lexlib.lxl for my own use. Made some other minor changes to suit my taste
also.

@ jpmendes,

1. The lexer wasn't designed to handle the coding style as module xx()
   <operations> {...}.  The <operations> could be a lot of different things
   with undetermined length. It'd be too complicated to consider that (note
   that comparing to other lexers comes with SynWrite, this lexer is already on
   the "very complicated" side).

So at this moment the best bet is to rewrite it to module xx() {
<operations> ... }

2. boolean shouldn't have the same style as operations. See below:

http://forum.openscad.org/file/n15485/160104_osc_lexer_demo.png

It's likely that something was changed during your modification. I
personally never edit Lexlib.lxl directly but going:

[Options]/[Customize lexer]   --- modify the current lexer
or 
[Options]/[Customize lexer library]   --- pick a lexer from a list 

You can go [Customize lexer library], pick a lexer, make a copy using the
icon on the menu. This will give you a new lexer like "OpenSCAD (copy)". You
then edit it, hit [Apply] on the button to see if it fits your need, or add
your own code to the example panel of "OpenSCAD (copy)" .

Ok, understood.
However when I mentioned the boolean operations I meant /intersection,
difference / and /union/, that have the same style as non boolean
/translation, rotation/ etc
My personal modification was to put/ intersection difference and union/ bold
italic,  creating:

   item
    DisplayName = 's_id_openscad_builtin_boolean'
    Font.Charset = DEFAULT_CHARSET
    Font.Color = clTeal
    Font.Height = -13
    Font.Name = 'Courier New'
    Font.Style = [fsBold, fsItalic]
  end

and

   item
    DisplayName = 'r_id_openscad_builtin_boolean'
    StyleName = 's_id_openscad_builtin_boolean'
    BlockType = btTagDetect
    ConditionList = <
      item
        TagList.Strings = (
          'difference'
          'intersection'
          'union')
        TokenTypes = 4
      end>
    HighlightPos = cpAny
    IgnoreAsParent = False
  end
