@ -14,18 +14,32 @@ Define/conditional compilation related commands:
This command will add 'gflag' to the global define list. This will have a similar effect as using the /D switch on the command line (only the define only becomes effective after the !define command).
\c !define VERSION 1.2
\S1{undef} !undef
\c gflag
Removes an item from the global define list. Note that $\{SYMBOL\} where SYMBOL is undefined will be translated to "$\{SYMBOL\}".
\c !define SOMETHING
\c !undef SOMETHING
\S1{ifdef} !ifdef
\c gflag [bcheck [gflag [...]]]
This command, when paired with an !endif command, will tell the compiler whether or not to compile the lines in between the two lines. If gflag is globally defined (using !define or the /D switch), then the contained lines will be compiled. Otherwise, they will be skipped. 'bcheck' can be specified as & (boolean and) or | (boolean or) along with more gflags -- precedence is simple, left to right.
\c !define SOMETHING
\c !ifdef SOMETHING
\c !echo "SOMETHING is defined"
\c !endif
\c !undef SOMETHING
\c !ifdef SOMETHING
\c !echo "SOMETHING is defined" # will never be printed
\c !endif

This command, when paired with an !endif command, will tell the compiler whether or not to compile the lines in between the two lines. If the macro gflag exists, then the contained lines will be compiled. Otherwise, they will be skipped. 'bcheck' can be specified as & (boolean and) or | (boolean or) along with more gflags -- precedence is simple, left to right.
\c !macro SomeMacro

This command allows to easily insert different code when different defines or macros are set. You can create blocks like !ifdef/!else/!endif, !ifdef/!else ifdef/!else/!endif etc.
\c !ifdef VERSION
\c OutFile installer-${VERSION}.exe
\c !else
\c OutFile installer.exe
\c !endif
\S1{endif} !endif
This command closes a block started with !ifdef, !ifndef, !ifmacrodef or !ifmacrondef.
@ -60,12 +86,24 @@ This command closes a block started with !ifdef, !ifndef, !ifmacrodef or !ifmacr
Inserts the contents of a macro that was created with !macro. If the macro was created with parameters, then you must pass as many parameters to the macro as it requires.
\c !macro Print text
\c DetailPrint "${text}"
\c !macroend
\c !insertmacro Print "some text"
\c !insertmacro Print "some more text"
\S1{macro} !macro
\c macro_name [parameter][...]
Creates a macro named 'macro_name'. All lines between the !macro and the !macroend will be saved. To insert the macro later on, use !insertmacro. !macro definitions can have one or more parameters defined. The parameters may be accessed the same way a !define would (e.g. $\{PARMNAME\}) from inside the macro.
\c !macro SomeMacro parm1 parm2 parm3
\c DetailPrint "${parm1}"
\c MessageBox MB_OK "${parm2}"
\c File "${parm3}"
\c !macroend
\S1{macroend} !macroend
Ends a macro that was started with !macro.
