Q: Farmer, Wolf, Goat and Cabbage Problem: full decision tree in C

I put a backtracking algorithm around the Farmer, Wolf, Goat and Cabbage problem - to see if there are any interesting branches, besides the (two) 7-step solutions. On first view it seems a dilemma. Then you realize it can be solved (by taking the goat back at step 4). Then you realize: it can al...

Q: Client-server application for logging running processes

My first client-server application. It's a simple Python script that gets a list of running processes from Server_1 and writes it to a datetime-named file on Server_2, every 5 seconds.

I have a question: for a library that is expected to be distributed by composer ... and this can be executed by CLI or by a web environment; It should have separate methods for execution or you would expect it to be the library that determines what environment it is running in.

Edward

@FranciscoNúñez I'm not sure. I think it would depend on what the library does and how it's expected to be used.

Is this something that is compiled to WebAssembly?

performance php object-oriented security

Edward

I'm not a PHP expert, but it looks like the theme is applied in the web environment but not via CLI. Is that correct?

Are there other differences?

Might it be possible to pass in a variable indicating the desired context?

Der Kommissar

@FranciscoNúñez The problem here is that you want the script to dynamically choose it, when the normal reality is to build three scripts: 1) the core functionality that abstracts the concepts (and in your case, returns things like comment: <comment text>); 2) the web-wrapper which digests the core output and formats it for web; 3) the CLI-wrapper which digests the core output and formats it for the CLI.

Francisco Núñez

I am making improvements to the highlighting and one of the points; is that it can be used both by CLI and by a browser ... but I don't know what is more convenient if doing it separately; then I have an output() method; and another output_cli() or implement a single output() method and within this determine if it is cli with php_sapi_name() === 'cli'

Edward

2:47 PM

Maybe output(cli) and output(browser)?

Leave it up to the user to specify the context instead of having the library attempt to determine it.

I think that would also simplify testing.

Der Kommissar

Really it should be $outputToFormat = runMyCustomVarDump(); cli_output($outputToFormat);

Edward

Yes, that's better.

Der Kommissar

Also if you were on my team and I saw ini_set I would be working with you to remove all that.

@DerKommissar thanks, I don't know how to remove it ... XD

Der Kommissar

If you're already going through the work of determining the environment just have it call the proper method internally

Edward

As a user of the library, I think I would prefer to have full control.

Francisco Núñez

@DerKommissar I'm looking for the easiest way to do it for novice XD programmers ...

@Edward ok

Edward

There's no technical reason one should not be able to emit HTML from the command line. I might, for instance, redirect it to a file.

Der Kommissar

You can eliminate the ini_set by emitting full HTML instead of relying on the auto-PHP HTML, which you should do anyway because technically PHP INI stuff is an outside dependency you have no true control over.

Of course you can't do that if you're using var_dump, so you'd have to do it yourself.

This is Stack Overflow and not Code Review. You should post your question over there.
