Matthias Koefferlein 712237e67b Implemented solution for issue #2145 (default_text_size option for GDS2 writer) 2025-09-08 23:23:05 +02:00
Matthias Koefferlein c437d75a01 [consider merging] Fixing two problems with layer mapping
1. Mapping "[*/*] 100/0:0/0" (for example) created 0/0
   two times when the input contains 100/0 and 0/0. Now
   it is a single layer only
2. The mapping table generated from strings now uses
   layer indexes from a range that should not collide
   with existing layer indexes.

Matthias Koefferlein 0dd6fca51e Implemented a fix for #1794 (giant meta info produces invalid GDS)
This fix solves two problems:
* Too large meta info data
* Too many meta info entries

The first problem is fixed by splitting the strings that serialize
the meta info.

The second problem is fixed by introducing prefixed strings that
indicate the attribute index within the string, not inside
the PROPATTR record.

The solution is backward compatible, although old versions will
not read all meta info and skip entries that exceed the GDS
capacity.

Caveat: the produced GDS files may contain duplicate PROPATTR
keys. This is not strictly illegal, but some third-party processors
may drop such entries.

Issue 1609 (#1613)
* Fixed issue #1609 (Cell.read doesn't read LayoutMetaInfo)

This also includes some more functions:
- Layout#merge_meta_info, Layout#copy_meta_info
- Layout#clear_all_meta_info
- Cell#merge_meta_info, Cell#copy_meta_info

In addition, meta info is merged when importing a layout from
another file (Layout/Import -> Other Layouts into current).

* Meta info support in layout diff (for testing), implemented meta info merge for GDS and OASIS readers with special conflict resolution modes

* Undo support for meta info - this way we do not loose meta info when we delete a cell and undo

Matthias Koefferlein 7bcbd607b7 Meta infos in GDS2 files do not make old KLayout versions fail always
Only these cases are not supported by old versions:
* Layout-object meta info
* Meta info on top cell (renders an empty layout)

Implemented #586 (issues with duplicate cell names) (#605)

check for unique cell names upon *writing* of a layout
file.

Matthias Koefferlein 99d3610a6a Implemented #527 (wildcard layer mapping targets)
commit d77702cd86066f3a97d740a95923fa598c2ff07b
Author: Matthias Koefferlein <matthias@koefferlein.de>
Date:   Sat Mar 28 21:28:39 2020 +0100

    Wildcard expansion feature on layer mapping

    Finished feature, added doc and test.

    The solution is to use placeholder indexes for the
    layer mapping which are substituted by the real
    layers when they are encountered.

Matthias Koefferlein ad03533a7b OASIS tests made robust against hash implementation
The text writer was made "normalizing": it will introduce
a certain element order (string sorting). This way, OASIS
files can be compared against golden data without
changes in the order due to different implementation of
hash containers.
