Detailed Description

Creates meshes from OpenSCAD .csg files.

Understands a subset of OpenSCAD .csg format.

Definition at line 465 of file mesh_CSG.h.

Member Function Documentation

◆ builder()

CSGBuilder& GEO::CSGCompiler::builder ( )

inline

Gets the CSGbuilder.

Returns: a reference to the CSGBuilder

Definition at line 485 of file mesh_CSG.h.

◆ is_modifier()

bool GEO::CSGCompiler::is_modifier ( int toktype ) const

protected

Checks if a token corresponds to an instruction or object modifier.

A modifier is one of '','#','!','*', where '' and '*' discard the subtree, '#' does not change anything and '!' replaces the result with the subtree (re-root). Note: in OpenSCAD, '' and '#' display the subtree as a transparent object.

◆ lookahead_token()

Token GEO::CSGCompiler::lookahead_token ( )

protected

Gets the next token without any side effect.

Parsing position remains at the same token.

◆ next_token()

Token GEO::CSGCompiler::next_token ( )

protected

Gets the next token.

Parsing proceeds to the next token.

◆ next_token_check()

void GEO::CSGCompiler::next_token_check ( char c )

protected

Checks that the next token is a given character.

If the next token is something else than the given character, then parsing stops with an error message.

Parameters

[in] c the character

◆ next_token_internal()

Token GEO::CSGCompiler::next_token_internal ( )

protected

Function to actually get the next token from the stream.

next_token() and lookahead_token() use a 1-token buffer to pretend that one can look at a token in advance without consuming it.

◆ set_verbose()

void GEO::CSGCompiler::set_verbose ( bool x )

inline

Displays (lots of) additional information.

Parameters

[in] x whether additional information should be displayed. Default is off

Definition at line 477 of file mesh_CSG.h.

◆ syntax_error() [1/2]

void GEO::CSGCompiler::syntax_error ( const char * msg )

protected

Throws an exception with an error message.

Parameters

[in] msg the error message to be displayed

◆ syntax_error() [2/2]

void GEO::CSGCompiler::syntax_error	(	const char *	msg,
		const Token &	tok
	)

protected

Throws an exception with an error message.

Parameters

[in]	msg	the error message to be displayed
[in]	tok	the currently parsed token, will be appended to the error message
