# InnoSetup cmdlinerunner

[cmdlinerunner](cmdlinerunner.c) — a helper DLL used to run external command-line programs from the installer, capture live console output, and get the exit code.

Example project: https://github.com/espressif/idf-installer/tree/main/src/InnoSetup

Example of usage:

```pascal

{ ------------------------------ Helper functions from libcmdlinerunner.dll ------------------------------ }

function ProcStart(cmdline, workdir: string): Longword;

  external 'proc_start@files:cmdlinerunner.dll cdecl';

function ProcGetExitCode(inst: Longword): DWORD;

  external 'proc_get_exit_code@files:cmdlinerunner.dll cdecl';

function ProcGetOutput(inst: Longword; dest: PAnsiChar; sz: DWORD): DWORD;

  external 'proc_get_output@files:cmdlinerunner.dll cdecl';

var

      SetLength(LogTextAnsi, 4096);

      Res := ProcGetOutput(Handle, LogTextAnsi, 4096)

      if Res > 0 then

      begin

        SetLength(LogTextAnsi, Res);

## Build

* Build cmdlinerunner DLL.

  - On Windows, it is possible to build using Visual Studio, with CMake support installed

    ```

    mkdir build

    cd build

    cmake -DCMAKE_BUILD_TYPE=Release ..

    cmake --build .  --config Release

    ```

    This will produce `Release/cmdlinerunner.dll`

  - On Linux/Mac, install mingw-w64 toolchain (`i686-w64-mingw32-gcc`). Then build the DLL using CMake:

    ```

    mkdir -p build

    cd build

    cmake -DCMAKE_TOOLCHAIN_FILE=../toolchain-i686-w64-mingw32.cmake -DCMAKE_BUILD_TYPE=Release ..

    cmake --build .

    ```

    This will produce `cmdlinerunner.dll` in the build directory.
