Exewrapper - run program in a configurable context

Runs an arbitrary child process and waits for its termination, while delegating the standard input, output and error to the child.

How to install

1. Install Rust - https://www.rust-lang.org/tools/install
2. Run CARGO_NET_GIT_FETCH_WITH_CLI=true cargo install --git https://git.wilem.eu/exewrapper.git

How to use

The wrapper will look for a config file at self path plus .conf at the end. For example, the wrapper is at C:\Users\ivan\bin\ashcmd.exe. The config file will be looked for at C:\Users\ivan\bin\ashcmd.exe.conf.

Full config contents with examples:

bin = 'C:\Users\ivan\bin\busybox.exe'
args = ["ash", "-c"]
rust_args = false
rust_args_as_one = false
debug = false

[env]
HOME = 'C:\Users\ivan'

Everything but bin is optional.

• rust_args_as_one = true will concatenate all exewrapper’s arguments with a space and provide it as a single argument to the child process. For example, with the config above, running ashcmd.exe echo 'hello world' will run

  • C:\Users\ivan\bin\busybox.exe
  • ash
  • -c
  • echo 'hello world'

  With cli_args_as_one = false it would’ve been

  • …
  • -c
  • echo
  • 'hello
  • world'

• rust_args = false disables Rust’s stdlib handling of the command line on Windows and bypasses the command line as is, as a single argument. This leaves the command line intact, whereas the Rust’s stdlib processing removes double quotes and does more stuff.

• [env] section allows setting / overriding environment variables for the child process.
