Migrating from another SynEdit ​

Applications written for pyscripter/TurboPack SynEdit only need the new unit names: classes, types and constants are unchanged, so the DFMs keep working.

The naming rule ​

OriginalEthea SynEditExample
SynEdit.pas (main unit)SynEdit.CoreTSynEdit, TCustomSynEdit
SynHighlighterXxxSynEdit.Highlighter.XxxSynEdit.Highlighter.Pas
SynEditXxxSynEdit.XxxSynEdit.Types, SynEdit.Highlighter
SynXxxSynEdit.XxxSynEdit.CompletionProposal, SynEdit.Unicode
dlgXxxSynEdit.dlgXxxSynEdit.dlgSearchText
SynEdit.inc, SynEditJedi.incSynEdit.Defines.inc, SynEdit.Jedi.inc

Exception: SynHighlighterAsm is SynEdit.Highlighter.Assembler (Asm is a reserved word and cannot be a unit name segment in the contains clause of a package).

Two ways to migrate ​

1. The migration script ​

cmd
python Tools\SynEditRename.py migrate <project folder> --apply

Without --apply the script only shows what it would change (dry-run). It updates:

  • the uses clauses and the {$I} directives;
  • the contains and requires clauses of the .dpk files;
  • the DCCReference items of the .dproj files;
  • the names of the runtime packages.

It changes only what is certainly a unit name, and reports (file and line) what must be fixed by hand: qualified references such as SynEditTypes.TBufferCoord, and string literals with old names. In client code SynEdit is often a variable name, so it is never replaced blindly.

Other commands: python Tools\SynEditRename.py list prints the table of the names, python Tools\SynEditRename.py aliases prints the value for the Unit aliases option.

2. Unit aliases ​

In Project Options > Delphi Compiler > Unit aliases paste the output of python Tools\SynEditRename.py aliases: the old names are resolved to the new units without touching the source code.

Behavior changes inherited from upstream ​

After July 2025 pyscripter/SynEdit moved some declarations:

  • the types that were in SynEdit are now in SynEdit.Types;
  • TSynEditorOptionsContainer moved from SynEditOptionsDialog to SynEdit.MiscClasses.

IncPaintLock and DecPaintLock are kept as aliases of BeginUpdate and EndUpdate.

Old and new unit names ​

The complete table is in the file Tools\SynEditRenames.json.
