CS.Coder Block Folding is an extension for the Delphi code editor that folds statement blocks. Delphi folds routines, classes and regions; Block Folding complements that with the blocks inside a routine, so a long method can be read one level at a time. It does not change your source.

Folded blocks show a small box after their first line. The unit in the screenshot is the sample that comes with the repository.

Summary

• Statement blocks. if with its else, for, while, with, try, case, repeat, asm and a standalone begin..end.
• Keyboard. Ctrl+Alt+B folds the block around the cursor and, on the first line of a folded block, opens it. Ctrl+Alt+Shift+B opens every fold of the unit.
• Mouse. − and + signs beside the code fold and open with a click.
• Your choice. Each kind of block, the shortcuts and the text shown on the folded line can be changed in the settings.
• Your source stays as it is. No {$REGION} is inserted and nothing is saved in the file. Folds last while the unit stays open.

Installation

Works with Delphi 11 (32-bit IDE) and Delphi 12 and 13 (32-bit and 64-bit IDE). No compiler and no administrator rights are needed.

1. Download CSCoderBlockFolding-<version>.zip from the Releases page, under Assets. Do not pick "Source code": that one has no installer.
2. Extract the whole zip into a folder of your choice.
3. Close Delphi.
4. Run Install.bat. It installs for the current Windows user in every supported Delphi it finds.
5. Open Delphi. The commands are in the main menu, under CS.Coder > Block Folding.

Updating: run the Install.bat of the newer zip, with Delphi closed. Your settings are kept.

Uninstalling: Uninstall.bat removes the extension and keeps your settings. Uninstall.bat /data also deletes the settings and the diagnostic log.

What's new

0.26.10.12a is the first public version. The notes of every version are on the Releases page.

Good to know

• The mouse signs are drawn when the IDE's own code folding is turned off.
• Routine bodies, classes and regions keep being folded by Delphi itself. A block that contains a {$REGION} is not folded by Block Folding.
• The About window follows the language of Windows. The menu and the settings window are in Portuguese in this version.
• Settings are kept in the Windows registry, one set per Delphi version. A log of what the extension did, for support, stays on your computer in %LOCALAPPDATA%\CSCoder\BlockFolding. The network is not used.

The complete documentation is on the product page (in Portuguese).

Build from source

build-plugin.ps1 -Version 11|12|13 [-Ide64] compiles the package with the command-line compilers of Delphi. Set your Delphi folders at the top of the script. One .dpk, in src/plugin/, serves the three Delphi versions.
