Port of apenwarr's redo to Rust

zombiezen/redo

This is a Rust port of Avery Pennarun's redo, which in turn is an implementation of Daniel J. Bernstein's redo build system. It includes parallel builds, improved logging, extensive automated tests, and helpful debugging features.

Installation

1. Download the binary for your platform from the latest release.
2. Unzip the archive.
3. Move the contents of the bin/ directory into a directory in your PATH.

If you use Visual Studio Code, you may be interested in installing the redo extension.

Getting Started

Borrowed from https://redo.readthedocs.io/en/latest/cookbook/hello/

Create a source file:

cat > hello.c <<EOF
#include <stdio.h>

int main() {
    printf("Hello, world!\n");
    return 0;
}
EOF

Create a .do file to tell redo how to compile it:

cat > hello.do <<EOF
# If hello.c changes, this script needs to be
# re-run.
redo-ifchange hello.c

# Compile hello.c into the 'hello' binary.
#
# $3 is the redo variable that represents the
# output filename.  We want to build a file
# called "hello", but if we write that directly,
# then an interruption could result in a
# partially-written file.  Instead, write it to
# $3, and redo will move our output into its
# final location, only if this script completes
# successfully.
#
cc -o $3 hello.c -Wall
EOF

Build and run the program:

redo hello &&
./hello

You can provide a default target by writing an all.do file:

echo 'redo-ifchange hello' > all.do &&
redo &&
./hello

The extensive documentation for Avery Pennarun's redo is relevant for this tool as well, since zombiezen/redo is a straight port.
