[New] Support `--no-progress` for `nvm install`, close #1079 #1422

  local NODE_OR_IOJS
  if [ "${FLAVOR}" = 'node' ]; then
    NODE_OR_IOJS="${FLAVOR}"
  fi
+  if [ "${NVM_NO_PROGRESS}" = "1" ]; then


For things like this it's best to test if the environment variable is non-zero length:

if [ -n "${NVM_NO_PROGRESS}" ]; then ... fi

Either it exists and has content or doesn't is how I've seen it typically tested in other projects which are bash-based. I tend to like that style of testing more.

    NODE_OR_IOJS="${FLAVOR}"
  fi
+  if [ "${NVM_NO_PROGRESS}" = "1" ]; then
+    PROGRESS_BAR="-s"


Please use:

PROGRESS_BAR="-sS"

-s by itself silences all output (including errors). However, I believe a user would want to know why something failed so -S will still properly surface errors to them. -sS will only output if there's an error.

Related to other feedback I think this should be (adding -sS and excluding -q):

... -e 's/-sS /-nv /' ...

You don't want -q because it will completely disable output including errors. From the wget man page -nv is non-verbose but will still display errors when they occur (akin to -sS).

Might I make a recommendation here as well?

if NVM_NO_PROGRESS="${NVM_NO_PROGRESS:-${noprogress}}" nvm_install_source ...

If you look up Parameter Expansion in the bash man page you'll find that ${VAR:-default} will only take the default value if $VAR is unset. The reason why this is useful is because it allows a user to set NVM_NO_PROGRESS globally as an environment variable on their system which will always disable progress without having to use the nvm --no-progress option. In a CI-like, environment I feel this would be desirable.

Just my two cents on environment variables and using defaults.

@ljharb do you agree with all the change requests from @samrocketman? If so, I can start to update the PR, thanks.

ljharb · 2017-03-17T07:36:50Z

@PeterDaveHello the comments look good; I'm confused why NVM_NO_PROGRESS can't just be "empty" or "nonempty" instead of a "noprogress" string?

@ljharb can you elaborate on the versions of software you're using? Considering what is involved in this PR perhaps versions of:

lsb_release -a
#alternatively instead of lsb_release: head -n1 /etc/issue
uname -rms
bash --version
curl --version
wget --version
sed --version

My mistake, should be fixed now.

This now appears to work in my local testing, thanks.

Is there any way we could test this? Perhaps one test could mock out nvm_download and assert on the presence of --progress-bar vs -sS, and then another test for nvm_download itself?

PeterDaveHello · 2017-03-21T05:22:33Z

I'm not sure what kind of assertion would it looks like, any suggestions?

ljharb · 2017-03-22T07:17:01Z

Take a look at test/fast/Unit tests/nvm_get_checksum and a number of other tests in that folder for inspiration.

ljharb · 2017-06-13T07:37:10Z

@PeterDaveHello it'd be great to get this in soon; have you had a chance to work on these tests?

PeterDaveHello · 2017-06-14T02:22:45Z

@ljharb sorry for the delay, I'd like to, but not sure when can I finish it, no offense, but I also wonder if it's a little bit rush, would that be possible that you can directly finish the tests?

PeterDaveHello · 2017-06-23T08:21:44Z

@ljharb please take a look, test added, not sure if it's good enough, thanks.

    NODE_OR_IOJS="${FLAVOR}"
  fi
+  if [ "${NVM_NO_PROGRESS-}" = "1" ]; then
+    PROGRESS_BAR="-sS"


should this be --silent --show-error, or would that make combining them tricky?

Is there a reason we ever don't want --show-error semantics?

I think it's because we use parameters like -L, -I, -C, so it's to maintain consistency to use a short parameter and maybe I should even use -# instead of --progress-bar?

As long as both forms work on the same systems, I'd prefer the long versions for readability.

Maybe revise this somewhere else? Consistency is important.

Fair. We can stick to the short versions now but please add the long ones in a comment.

I mentioned this before (can't remember where). The long option is not always available in some versions of curl. However, the short option definitely is. For compatibility, I recommend sticking to the short option for this specific feature.

Thanks, in that case let's stick with the short options (but comment the long ones, for clarity)

+  else
+    PROGRESS_BAR="--progress-bar"


where is "PROGRESS_BAR", as defined here, referenced?

You mean the definition?

no - I mean that lines 2017-2021 seem useless since nothing ever uses PROGRESS_BAR in this code path.

I think nvm_download_artifact() will use it

It can't use it unless it's passed or exported.

hmmm ... shell's variable passing is always confusing, it looks working. I pass it anyway ;)

ljharb

I'll try this out locally, then merge.
