From 137c73f3e42281de67bde8f1c0b16938f5b8aeeb Mon Sep 17 00:00:00 2001 From: Paulo Henrique Silva Date: Wed, 14 Jan 2015 14:33:00 -0200 Subject: Many additions to Excellon parsing/creation. CAUTION: the original code used zero_suppression flags in the opposite sense as Gerber functions. This patch changes it to behave just like Gerber code. * Add metric/inch conversion support * Add settings context variable to to_gerber just like Gerber code. * Add some missing Excellon values. Tests are not entirely updated. --- gerber/excellon_statements.py | 114 +++++++++++++++++++++++++++++++----------- 1 file changed, 86 insertions(+), 28 deletions(-) (limited to 'gerber/excellon_statements.py') diff --git a/gerber/excellon_statements.py b/gerber/excellon_statements.py index feeda44..c4f4015 100644 --- a/gerber/excellon_statements.py +++ b/gerber/excellon_statements.py @@ -28,7 +28,8 @@ __all__ = ['ExcellonTool', 'ToolSelectionStmt', 'CoordinateStmt', 'CommentStmt', 'HeaderBeginStmt', 'HeaderEndStmt', 'RewindStopStmt', 'EndOfProgramStmt', 'UnitStmt', 'IncrementalModeStmt', 'VersionStmt', 'FormatStmt', 'LinkToolStmt', -
