IDE Macros in paths and filenames

│ Deutsch (de) │ English (en) │ español (es) │ français (fr) │ português (pt) │ русский (ru) │

Macros are used in the following format. Replacing the macro-name part with one of the macros listed below.

$(macro-name)

For example: This Unit Output directory format is often used for Lazarus Packages:

lib/$(TargetCPU)-$(TargetOS)

under a x86 Linux 32-bit system that would equate to: lib/i386-linux
under a x86 Linux 64-bit system that would equate to: lib/x86_64-linux

There are also some macro functions that use the following format:

$macro_name(parameters)

For example

$Ext(unit1.pas)

will give .pas.

General Purpose

• Col - current column in source editor
• Row - current row in source editor (screen, can differ to byte position due to tabs and UTF-8)
• CurToken - current token at the cursor in the source editor
• EdFile - current filename in the source editor
• Params - run parameters of the current project
• Prompt - ask the user for a value. This is an interactive macro.
• RunCmdLine - the command to launch the project
• Save - save current file in source editor
• SaveAll - save all
• TargetCmdLine - the project executable plus run parameters

Filename Parts

• Ext(filename) - macro function for ExtractFileExt
• MakeDir(filename) - macro function for AppendPathDelim
• MakeFile(filename) - macro function for ChompPathDelim
• MakeExe(filename) - change file extension to .exe under Windows, nothing under Linux, BSD, OS X
• MakeLib(filename) - change file extension to .dll under Windows, under Linux/BSD change to lowercase libname.so, under OS X to libname.so (since 0.9.29)
• Name(filename) - macro function for ExtractFileName
• NameOnly(filename) - macro function for ExtractFileNameOnly
• Path(filename) - macro function for ExtractFilePath

Paths and Parts

• Env(name) - macro function for environment variables given to the IDE (not project nor debugger) (see GetEnvironmentVariableUTF8) (since 0.9.27)
• CompPath - compiler path set in the environment options
• ConfDir - directory where the IDE stores its config files
• ExeExt - executable file extension for the operation system, independent of project's target OS. To get the extension for the current project target OS use $MakeExe().
• FPCSrcDir - FPC source directory set in environment options
• FPCVer - FPC version (since 0.9.25). For example '2.2.2'. This version is fetched from the compiler $(CompPath), which path is set in the environment options.
• LanguageID - IDE language, for example en for english, de for german
• LanguageName - IDE language name, the translated name of the current language. For instance: Deutsch for german.
• LazarusDir - Lazarus source directory set in environment options
• LCLWidgetType - LCL widgetset of the current project
• ProjFile - the full filename of the main source of the current project (.lpr)
• ProjPath - the project directory (the directory of the .lpi file)
• TargetFile - the output file of the current project (e.g. the executable or the library)
• TestDir - Test directory set in the environment options
• SrcOS - 'unix' for linux, darwin, bsd. 'win' for win32, win64, wince
• TargetCPU - Target CPU of the current project
• TargetOS - Target OS of the current project
• Make - path to the make utility (gmake under BSD) (since 0.9.29)
• ProjIncPath - include path of project directory
• ProjOutDir - path of project output directory (e.g. where the .ppu files are created) (since 0.9.27)
• ProjPublishDir - publishing directory of the current project
• ProjSrcPath - source path of project directory
• ProjUnitPath - unit path of project directory
• Project(param) - macro function for various values:
  • Project(UnitPath) - unit path of project directory
  • Project(SrcPath) - source path of project directory
  • Project(IncPath) - include path of project directory
  • Project(InfoFile) - filename of the project information file (.lpi) (since r15287, 0.9.25)
  • Project(OutputDir) - directory where the project's ppu files are created (since 0.9.27)
• Package macros - these can be used in the fields of a package. For example in the search paths of a package. To use them elsewhere give a package name as parameter.
  • PkgDir() - macro function for the directory (location of the .lpk) of a package ID given as parameter
  • PkgIncPath(id) - macro function for the include path of a package ID given as parameter
  • PkgOutDir(id) - macro function for the output directory of a package (e.g. where the ppu files are created)
  • PkgSrcPath(id) - macro function for the source path (unit path + src path) of a package ID given as parameter
  • PkgUnitPath(id) - macro function for the unit path of a package ID given as parameter
• IDEBuildOptions - the extra options of the 'Configure Build Lazarus' dialog (since 0.9.29)
• PrimaryConfigPath - the directory of the IDE's configuration files (since 0.9.31)
• SecondaryConfigPath - the directory of the IDE's configuration templates (since 0.9.31)
• FallbackOutputRoot - the directory where the IDE puts ppu files if the output directory of a package is not writable. Default: $(PrimaryConfigPath)/lib. Since 0.9.31.
