00:19 <postmodern> is there an example of using Process.run and reading stdout of the process? having trouble using it with `output:` and `IO::Memory.new`

00:19 <postmodern> also is there a way to do full streaming I/O from the process. I don't want to read the entire stdout once the process has exited, but read it as output is received.

01:33 <FromGitter> <Blacksmoke16> postmodern: read std while the process is running, or to STDOUT, or to some other io?

01:34 <FromGitter> <Blacksmoke16> because if you the block version of `.run`, you can have access to it while its running, or when using the non block version can set `output: :inherit` to use IO of parent process (stdout), or to an `IO` instance

01:35 <FromGitter> <Blacksmoke16> ah based on your 2nd line, sounds like you want the block version

02:44 <postmodern> i kind of wish Process had a .popen method that made this task easier to do in one method call

02:52 <FromGitter> <Blacksmoke16> Got an example of what you want to do?

02:58 <postmodern> `Process.run(command) { |process| process.stdout.each_line { |line| ... } }`

02:58 <postmodern> er `Process.popen(command) { |process| process.stdout.each_line { |line| ... } }`

02:59 <postmodern> it would be nice if the stdout IO object would be created for you instead of being passed in as an argument

03:04 <FromGitter> <Blacksmoke16> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=621452c88db2b95f0a33fac1]

03:05 <FromGitter> <Blacksmoke16> https://crystal-lang.org/api/Process/Stdio.html, notice how it can also be a https://crystal-lang.org/api/Process/Redirect.html

03:32 <postmodern> ah `output: :pipe` is what i want, thanks

03:32 <postmodern> i still think a `.popen` method that simply sets `output: :pipe`, etc, would be helpful since `popen` is a pretty common function

04:24 <FromGitter> <moe:busyloop.net> i think it's mostly a matter of improving the docs (more examples). i've used `Process` fairly extensively and until now had no idea you could do the above either 🤷‍♂️

06:28 <postmodern> hmm is there no `IO#read : String` method? These specs I'm porting to Crystal use it to verify the IO stream from the Process.run command

06:51 <FromGitter> <moe:busyloop.net> there is `read_string`
