Funide

The funide IDE and editor tooling for the Fun programming language.

This repository holds only the IDE layer: the Delphi/VCL desktop editor and the Fun TextMate grammar. The Fun language itself (interpreter, parser, runtime library, regex) is not duplicated here; it is compiled from the neighbouring fun project, which is released separately.

---

Contents

• src/ide/ — the IDE units: the main window and debugger glue (ide.pas/ide.dfm), the Fun/Regex/FD syntax highlighters (funsyntax.pas, regexsyntax.pas, fdsyntax.pas), and resources.
• src/prj/ide/ — the Delphi project (funide.dpr, funide.res) and the Windows build scripts.
• syntaxes/fun.tmLanguage.yaml — the Fun TextMate grammar (scopeName: source.fun) used for syntax highlighting. It is derived from the Fun implementation's lexer (src/parse/bnf/lex.l), grammar (src/parse/bnf/yacc.y) and keyword table (src/parse/id.inc).

Relationship to the fun project

funide does not contain a copy of the Fun language. funide.dpr and ide.pas link directly against the fun sources:

• funide.dpr references the Fun regex engine with relative unit paths:

  ide  in '..\..\ide\ide.pas'          // this repository
  pcrd in '..\..\regex\pcre\pcrd.pas'  // the `fun` project
  pcre in '..\..\regex\pcre\pcre.pas'  // the `fun` project

• ide.pas uses the Fun units by name:

  uses fun, base, core, host, parse, pcre, ui, io;

Those relative paths and unit names resolve only when the IDE layer sits inside the fun source tree. The build scripts therefore merge this repository's src/ide and src/prj/ide into the fun checkout before compiling:

funide/src/ide      ->  <FUN_ROOT>\src\ide
funide/src/prj/ide  ->  <FUN_ROOT>\src\prj\ide

The Fun units (src/core, src/lib, src/parse, src/regex, src/3rd, src/utils) come from <FUN_ROOT> unchanged; the compiler unit search path (-U) is filled from it. This keeps the Fun implementation in exactly one place while the IDE stays in this repository.

Thus, at build time, the tree looks like:

<FUN_ROOT>/                          # a checked-out `fun` project
├── src/
│   ├── core/  lib/  lib/ui/  parse/  regex/  regex/pcre/  utils/  3rd/   # from `fun`
│   ├── ide/                          # copied from funide/src/ide
│   └── prj/
│       ├── fun/                      # from `fun`
│       └── ide/                      # copied from funide/src/prj/ide
└── fun/                              # distribution folder; funide.exe is written here

The copied files appear as untracked files in the fun checkout. That is expected; the IDE sources are maintained here, not there.

Building

funide.exe is a 32-bit Windows VCL application built with Delphi.

Prerequisites

Item	Notes
A fun checkout	The language sources funide compiles against. Set FUN_ROOT to it.
Delphi 2006 or 2009	DELPHI2006 / DELPHI2009 are used by make-2006.bat / make-2009.bat. The 2006 build is ANSI; the 2009 build is Unicode.
SynEdit	The editor component. Point SYNCEDIT at the folder containing SynEdit.inc and the SynEdit*.pas sources.
VirtualTrees	The tree view component. Point VST at the folder containing VirtualTrees.pas.
PCRE 8 (8-bit)	Required for the Fun regex engine. Build it as described in the fun project's README (src/regex/pcre/make.bat).

SynEdit and VirtualTrees are third-party components and are not vendored here.

Toolchain configuration

All machine-specific paths live in one file, src/prj/ide/setenv.bat, which mirrors fun/src/prj/fun/setenv.bat. Edit it once, or pre-set the variables in your shell:

Variable	Meaning	Default
FUN_ROOT	Root of the fun checkout	..\..\..\..\fun (a sibling of this repository)
DELPHI2006	Delphi 2006 install root	D:\Borland\Delphi2006
DELPHI2009	Delphi 2009 install root	D:\Borland\Delphi2009
SYNCEDIT	SynEdit source folder	D:\Delphi\SynEdit\Source
VST	VirtualTrees source folder	D:\Delphi\VirtualTreeviewV5.5.3\Source

Every if not defined guard lets a value you set beforehand win.

Build steps

cd src\prj\ide
make-2009.bat            # or: make-2006.bat

make-2009.bat:

1. loads the toolchain from setenv.bat;
2. runs sync-ide.bat to copy src/ide and src/prj/ide into FUN_ROOT;
3. runs dcc32 funide.dpr with the Fun unit search path and the IDE defines.

The resulting funide.exe is written to <FUN_ROOT>\fun, next to fun.exe. Extra dcc32 switches are passed through, e.g. make-2009.bat -B.

Target	Script	Toolchain
Windows 32-bit	src/prj/ide/make-2006.bat	Delphi 2006
Windows 32-bit	src/prj/ide/make-2009.bat	Delphi 2009

The IDE is Windows/VCL only, so there is no Linux or Free Pascal target.

Syntax highlighting grammar

syntaxes/fun.tmLanguage.yaml is the upstream source that GitHub Linguist vendors (as a git submodule) to provide syntax highlighting for .fun files:

• vendor/grammars/fun submodule points at this repository
• grammars.yml: vendor/grammars/fun: [source.fun]
• languages.yml: the Fun entry's tm_scope is source.fun
