[![Travis CI](https://travis-ci.org/jdidion/subby.svg?branch=master)](https://travis-ci.org/jdidion/subby)
[![Code Coverage](https://codecov.io/gh/jdidion/subby/branch/master/graph/badge.svg)](https://codecov.io/gh/jdidion/subby)

Subby is a small Python library with the goal of simplifying the use of subprocesses. Subby is similar to [delegator.py](https://github.com/amitt001/delegator.py), but it adds a few additional features and excludes others (e.g. no `pexpect` support).

## Requirements

The only requirement is python 3.6+. There are no other 3rd-party runtime dependencies. The `pytest` and `coverage` packages are required for testing.

## Installation

`pip install subby`

## Usage

Subby's primary interface is the `run` function. It takes a list of commands and executes them. If there is are multiple commands, they are chained (i.e., piped) together.

```python
import subby

# We can pass input to the stdin of the command as bytes
input_str = "foo\nbar"

# The following three commands are equivalent; each returns a
# `Processes` object that can be used to inspect and control
# the process(es).
p1 = subby.run([["grep foo", "wc -l"]], stdin=input_str)
p2 = subby.run(("grep foo", "wc -l"), stdin=input_str)
p3 = subby.run("grep foo | wc -l", stdin=input_str)

# The `done` property tells us whether the processes have finished
assert p1.done and p2.done and p3.done

# The `output` property provides the output of the command
assert p1.output == p2.output == p3.output == "1"
```

### Raw mode

By default, text I/O is used for stdin/stdout/stderr. You can instead use raw I/O (bytes) by passing `mode=bytes`.

```python
import subby

assert b"1" == subby.run(
    "grep foo | wc -l", stdin="foo\nbar", mode=bytes
).output
```

### Non-blocking processes

By default, the `run` function blocks until the processes are finshed running. This behavior can be changed by passing `block=False`, in which case, the caller is responsible for checking the status and/or calling the `Processes.block()` method manually.

```python
import subby
import time

p = subby.run("sleep 10", block=False)
for i in range(5):
    if p.done:
        break
    else:
        time.sleep(1)
else:
    # A timeout can be used to kill the process if it doesn't
    # complete in a certain amount of time. By default, block()
    # raises an error if the return code is non-zero.
    p.block(timeout=10, raise_on_error=False)
    
    # The process can also be killed manually.
    p.kill()

# The `Processes.ok` property is True if the processes have
# finished and the return code is 0.
if not p.ok:
    # The `Processes.output` and `Processes.error` properties
    # provide access to the process stdout and stderr.
    print(f"The command failed: stderr={p.error}")
```

### Convenience methods

There are also some convenience methods to improve the ergonomics for common scenarios.

* `subby.cmd`: Run a single command. Equivalent to calling `subby.run([cmd], ...)`, where `cmd` is a string (with no '|') or list of strings.
* `subby.sub`: Equivalent to calling `subby.run` with `mode=str` and `block=True` and returning the `output` attribute (stdout) of the resulting `Processes` object.

```python
import subby

assert subby.cmd("grep foo", stdin="foo\nbar").output == "foo"
assert subby.cmd(["grep", "foo"], stdin="foo\nbar").output == "foo"

assert subby.sub("grep foo | wc -l", stdin="foo\nbar") == "1"
```

### stdin/stdout/stderr

Subby supports several different types of arguments for stdin, stdout, and stderr:

* A file: specified as a `pathlib.Path`; for stdin, the content is read from the file, whereas for stdout/stderr the content is written to the file (and is thus not available via the `output`/`error` properties).
* A bytes string: for stdin, the bytes are written to a temporary file, which is passed to the process stdin.
* One of the values provided by the `StdType` enumeration:
    * PIPE: for stdout/stderr, `subprocess.PIPE` is used, giving the caller direct access to the process stdout/stderr streams.
    * BUFFER: for stdout/stderr, a temporary file is used, and the contents are made available via the `output`/`error` properties after the process completes.
    * SYS: stdin/stdout/stderr is passed through from the main process (i.e. the `sys.stdin/sys.stdout/sys.stderr` streams).

By default, the stderr streams of all processes in a chain are captured (you can disable this by passing `capture_stderr=False` to `run()`).

```python
import subby
p = subby.run("echo -n hi | tee /dev/stderr | tee /dev/stderr")
assert p.output == b"hi"
assert p.get_all_stderr() == [b"", b"hi", b"hi"]
```

### Logging

By default, all executed commands are logged (with loglevel INFO). You can disable this behavior by passing `echo=False` to `run()`.

```python
import subby
subby.run("touch foo")  # Echoes "touch foo" to the log with level INFO
subby.run("login -p mypassword", echo=False)  # Does not echo mypassword
```

### Return codes

By default, Subby treats a return code of `0` as success and all other return codes as failure. In some cases, this is not the desired behavior. A well-known example is `grep`, which has a returncode of `1` when no lines are matched. To ignore additional return codes, set the `allowed_return_codes` keyword argument to `run()`.

```python
import subby
subby.run("echo foo | grep bar")  # Raises CalledProcessError
subby.run("echo foo | grep bar", allowed_return_codes=(0, 1))
```
## Contributing

Subby is considered to be largely feature-complete, but if you find a bug or have a suggestion for improvement, please submit an issue (or even better, a pull request).

## Acknowledgements

Subby was inspired by [delegator.py](https://github.com/amitt001/delegator.py).

Subby was originally written as part of the [dxpy.sugar](https://github.com/dnanexus/dx-toolkit/tree/SCI-1321_dx_sugar/src/python/dxpy/sugar) package, but because it is (hopefully) useful more generally, it is being made available as a separate package.
