Unable to compile "Hello World" program from README about eo

[volodya-lombrozo]

@yegor256 @maxonfjvipon Could you take a look, please?

[github-actions]

@volodya-lombrozo thanks for the report, here is a feedback:

Problems

• The bug report requires a more detailed and precise title. For example, the title 'Unable to compile "Hello World" program from README' better describes the specific problem.
• The report does not include information regarding the system where the bug was recreated. Such information is fundamental for debugging and resolving the issue.
• The report fails to state whether the bug occurs consistently or intermittently. This detail is crucial for tracking and rectifying the bug.

I would recommend adding a "Steps to Reproduce" section to make the bug easier for developers to replicate.

Please fix the bug report in order it to get resolved faster.

@volodya-lombrozo should be:

# Comment here.
[args] > app
  QQ.io.stdout > @
    "Hello, world!\n"

[volodya-lombrozo]

@maxonfjvipon Where is the difference? Why do I need to add # Comment here.?

[maxonfjvipon]

@volodya-lombrozo comments are mandatory in front of top level abstract objects

[volodya-lombrozo]

@maxonfjvipon btw, it didn't help:

cat app.eo 
# Comment here.
[args] > app
  QQ.io.stdout > @
    "Hello, world!\n"

Output:

@volodya-lombrozo it helps, but there's other error, please try to use --parser=0.38.4 --home-tag=0.38.4 flags

[volodya-lombrozo]

@volodya-lombrozo comments are mandatory in front of top level abstract objects

omg... Why?
Maybe we should update README file then? What do you think?

[maxonfjvipon]

@volodya-lombrozo yes, we should, we have a ticket for it

[volodya-lombrozo]

@maxonfjvipon from this #921 :

The severity level should be warning.

Why this feature prevents the build then?

[maxonfjvipon]

@volodya-lombrozo after this we made a mandatory comment a part of EO grammar, so if you miss comment - it can't be parsed

[volodya-lombrozo]

@maxonfjvipon as for this:

@volodya-lombrozo it helps, but there's other error, please try to use --parser=0.38.4 --home-tag=0.38.4 flags

It helped, but gave the following output with many errors:

@volodya-lombrozo yes, it's a known problem, it'll be resolved when whole eo-runtime is well documented
