Pub transformer that compiles .asm files to .exe.


I created this for use with my experiment WinDart, to have Dart files in my web directory compiled to MASM Assembly, and then assembled and linked to .exe files.


You will need MASM32 installed, and it to be installed to C:\masm32. Alternatively, you can pass an masm_path in the configuration, and ML and LINK will be run from that directory.

  masm: ^1.0.0-dev needs


This library is a transformer, and supports some options.

- windart
- masm

Supported options:

  • run (bool) - If set to true, then the executable will be run on completion.
  • run_args (List<String>) - Can be included to pass them to resulting executable.
  • ml (Map) - Options to pass to ML. Option values should be strings, or true.
  • link - Same as ml (above), but these will be passed to LINK.
  • masm_path (String) - The path to the MASM installation. Default: "C:\\masm32"


run: false
  c: true
  coff: true
  Cp: true
  LIBPATH: "C:\\masm32\\lib"

Analysis issues and suggestions

Fix dependencies in pubspec.yaml.

Running pub upgrade failed with the following output:

ERR: The current Dart SDK version is 2.1.0.
 Because masm depends on barback >=0.6.2 which requires SDK version >=0.6.2 <2.0.0 or >=2.0.0-dev.17.0 <2.0.0, version solving failed.
