act

Describe issue

Check out the following workflow. There are 3 scenarios all of which should work. I'm trying to use a variable with expression to control job execution via if.

But the first one doesn't, where the variable uses an expression, and then there's another expression references it. Interestingly, the 2nd variation does work:

if: ${{ env.VAR == 'foo' }} # ❌
if: ${{ env.VAR }} == 'foo' # ✅

But everything works as expected with plain variables, e.g., VAR: 'foo' vs. VAR: ${{ true && 'foo' || 'bar' }}.

I'm guessing act might be interpreting values "on demand" and this doesn't happen as expected inside a "nested" expression?

Originally created by @iby on GitHub (Jan 12, 2024). Original GitHub issue: https://github.com/nektos/act/issues/2152 ### Bug report info ```plain text act version: 0.2.57 GOOS: darwin GOARCH: arm64 NumCPU: 14 Docker host: DOCKER_HOST environment variable is not set Sockets found: $HOME/.colima/docker.sock Config files: /Users/iby/.actrc: -P ubuntu-latest=catthehacker/ubuntu:act-latest -P ubuntu-22.04=catthehacker/ubuntu:act-22.04 -P ubuntu-20.04=catthehacker/ubuntu:act-20.04 -P ubuntu-18.04=catthehacker/ubuntu:act-18.04 Build info: Go version: go1.21.5 Module path: command-line-arguments Main version: Main path: Main checksum: Build settings: -buildmode: exe -compiler: gc -ldflags: -X main.version=0.2.57 DefaultGODEBUG: panicnil=1 CGO_ENABLED: 1 CGO_CFLAGS: CGO_CPPFLAGS: CGO_CXXFLAGS: CGO_LDFLAGS: GOARCH: arm64 GOOS: darwin ``` ### Command used with act ```sh act ``` ### Describe issue Check out the following workflow. There are 3 scenarios all of which should work. I'm trying to use a variable with expression to control job execution via `if`. But the first one doesn't, where the variable uses an expression, and then there's another expression references it. Interestingly, the 2nd variation does work: ``` if: ${{ env.VAR == 'foo' }} # ❌ if: ${{ env.VAR }} == 'foo' # ✅ ``` But everything works as expected with plain variables, e.g., `VAR: 'foo'` vs. `VAR: ${{ true && 'foo' || 'bar' }}`. I'm guessing `act` might be interpreting values "on demand" and this doesn't happen as expected inside a "nested" expression? ### Link to GitHub repository _No response_ ### Workflow content ```yml on: push: # ❌ VAR expression env: VAR: ${{ true && 'foo' || 'bar' }} jobs: job-1: runs-on: ubuntu-latest steps: - run: echo $VAR job-2: runs-on: ubuntu-latest if: ${{ env.VAR == 'foo' }} steps: - run: echo $VAR # ✅ VAR expression #env: # VAR: ${{ true && 'foo' || 'bar' }} #jobs: # job-1: # runs-on: ubuntu-latest # steps: # - run: echo $VAR # job-2: # runs-on: ubuntu-latest # if: ${{ env.VAR }} == 'foo' # steps: # - run: echo $VAR # ✅ Plain VAR #env: # VAR: 'foo' #jobs: # job-1: # runs-on: ubuntu-latest # steps: # - run: echo $VAR # job-2: # runs-on: ubuntu-latest # if: ${{ env.VAR == 'foo' }} # steps: # - run: echo $VAR ``` ### Relevant log output ```sh WARN ⚠ You are using Apple M-series chip and you have not specified container architecture, you might encounter issues while running act.

All posted workflows in this issue are incorrect and wouldn't work in official GitHub Actions.

env is not available in jobs.*.if, the bad case to check this is not implemented in act.

The second option actually completely incorrectly evaluates to true…

In my opinon that they evaluate to true is correct, because this matches a well known bug in GitHub Actions Job If and act is expected you to help to detect that locally.
If you tell me that GitHub fixed that bug together with a reproducable workflow, then yes act should follow the fix of GitHub Actions.

Hey @ChristopherHX! Thanks for the quick feedback and insights!

Ha! I rely too much on act lately to avoid testing it on GitHub… 🥲

In case anyone else stumbles upon this, see context availability docs.

P.S. env context is available inside jobs.<job_id>.steps.if. I guess a good workaround for jobs.<job_id>.if is to use an earlier job output.

@ChristopherHX on the same note, does act performs any workflow file validation? I was going to suggest using rhysd/actionlint, but looks like it's already in dependencies. But act hasn't failed the workflow file validation when I ran it, like GitHub does, or like actionlint does in their playground which matches GitHub. Would be fantastic to have that behavior out of the box?

rhysd/actionlint, but looks like it's already in dependencies

Expression parsing logic is used by act from actionlint. The rest is still completly independent.

For example act might run workflows, actionlint would complain about if actionlint is right or not depends on the used functionality.

The best linter is the official GitHub Actions Vscode extension, because it uses a ts port of the exact same parser used by the GitHub Actions Service.
It also autocompletes your expressions.

Sorry, but nektos/act is not my own project, e.g. I depend on other peoples approval to do anything here
Lately I'm struggeling to get two reviews in an acceptable time (within 30days) for new features in act, while the old review requirements are still intact. I'm currently avoiding starting new features, bejond these which still await reviews since a couple of months, to avoid investing work in potenteally abandoned features due to missing reviewers
