Setup installer

Since: 1.28.3-alpha

One Inno Setup installer for the engine, Graphviz dot, the IDE plugin, ConvRulesEditor, drag-lint-graph and YADF.

drag-lint-setup-<version>.exe installs the whole tool set per user or for all users, registers the IDE plugins only where RAD Studio 13 is installed, and uninstalls only what it wrote.

Details

drag-lint-setup-<version>.exe installs the whole drag-lint tool set in one go: the engine, its rules and parser DLLs, the draglint:// helper, Graphviz dot, the RAD Studio plugin, ConvRulesEditor, drag-lint-graph and YADF. It is an Inno Setup 6 installer; status: experimental until it has passed a clean-machine test.

For the manual, zip-based route see Installation.

What you choose

Who it is for. The first page asks Just for me (the default -- no admin rights, installs under %LOCALAPPDATA%\Programs\drag-lint) or All users (Windows asks for admin rights, installs under Program Files). The IDE plugin registration and the draglint:// links are per user in both modes. Per user means the account that RUNS setup: if Windows asks for a different administrator account, the plugin and links are registered for that account, not yours -- install Just for me from your own account instead.

Components. Everything is ticked in a full install.

Component	What you get
engine, rules and chart scripts	always installed
ConvRulesEditor	the conversion-rules editor
drag-lint-graph	the call-graph tool
Graphviz dot	`dot.exe` and its DLLs -- the charts need it
IDE plugin (32-bit IDE / 64-bit IDE)	the `drag-lint` menu in RAD Studio 13
YADF formatter	`YADF.exe` and `YADFSetup.exe` (its settings editor)
YADF IDE plugin (32-bit IDE / 64-bit IDE)	YADF's RAD Studio menu and Options page

An IDE plugin is offered only for an IDE that is actually installed: on a machine without RAD Studio 13 those lines are greyed out and say why. A BPL loads only in the IDE version it was built for, and this release builds for RAD Studio 13 (37.0) only.

Tasks.

Register draglint:// links (ticked) -- clicking a node in a chart opens that line in the IDE. If links are already registered, setup asks before replacing them.
Register drag-lint as an MCP server (not ticked) -- for Claude Code and VS Code.

What it needs

Windows x64.
No PowerShell. Every chart question is answered by the engine itself; setup neither bundles nor looks for PowerShell and installs no .ps1 file.
RAD Studio must be closed when installing or uninstalling a plugin -- a loaded BPL is locked. Setup refuses with that message rather than half-copying.

What it changes, and what uninstall undoes

Change	Uninstall
files under the install folder	removed
`bin\drag-lint.json` (starter index manifest, no projects)	kept -- after the first run it is your file
one `Known Packages` value per plugin, named by its installed path	that value removed; other packages untouched
plugin setting `HKCU\Software\drag-lint\DelphiPlugin\ExePath`	removed only if it still points at this install
`HKCU\Software\YADF\ExePath`	removed only if it still points at this install
`draglint://` registration	unregistered only if this setup registered it
MCP entries (if ticked)	removed

Setup never overwrites an ExePath that already points at a working engine or YADF elsewhere without asking, and a silent install never overwrites one.

If the same plugin is already registered from another folder (a developer's repository build, say), setup warns: two copies of one package make the IDE refuse to load one of them. A silent install does not ask: it skips that plugin and says so in the setup log.

Updating

Run the newer setup over the old one; it upgrades in place and keeps your settings and drag-lint.json. drag-lint > About > Check for Updates in the IDE tells you when a newer release exists.

If a release changes the extractor version, every index on the machine is re-parsed on its next use -- the release notes say when.

Building the setup

pwsh -File installer\Build-Installer.ps1            # -> installer\Output\drag-lint-setup-<version>.exe
pwsh -File installer\Build-Installer.ps1 -DryRun    # checks only

The version comes from DRAGLINT_VERSION; the build stops if the engine being shipped reports a different one, or if any source file is missing. Sources default to the deployed third_party\dll-win64 / dll-win32, C:\Projects\YADF (Release builds) and the Graphviz 16.1.0 bin folder; each is a parameter. Licences shipped: drag-lint (MIT), tree-sitter and both grammars (MIT), delphi-tree-sitter (MIT), Graphviz (EPL-2.0), YADF.
