winprint VS murex

I built a cross platform app to print 'pretty formatted' source code [1]. I didn't want to re-invent the wheel on formatting source code, so looked at all the existing libraries. Originally I figured formatting to HTML, and then building a print-friendly HTML render would work. But this proved super challenging. I tried a dozen HTML engines (including Chromium) but none gave me enough control to render just a single page of the original source file.

Then I noticed Pygments, a Python-based library for pretty formatting source code, has an option to output an ANSI formatted file. I quickly found a bunch of libraries that could render ANSI formatted text to a print canvas.

In the end, I put the original source code file through 'pygmentize -16m -o tempfile.an` (`16m` is the 16M color terminal ANSI formatter) and pipe the `tempfile.an` through a print-optimized renderer to actually print the source code.

ANSI escapes FTW!

This is how murex works too https://github.com/lmorg/murex/blob/master/config/defaults/p...

I agree. I’ve written about this before but this is what murex (1) does. It reimplements some of coreutils where there are benefits in doing so (eg sed, grep etc -like parsing of lists that are in formats other than flat lines of text. Such as JSON arrays)

Mutex does this by having these utilities named slightly different to their POSIX counterparts. So you can use all of the existing CLI tools completely but additionally have a bunch of new stuff too.

Far too many alt shells these days try to replace coreutils and that just creates friction in my opinion.

This is exactly what Murex shell does. It has lots of builtin tools for querying structured data (of varying formats) but also supports POSIX pipes for using existing tools like `jq` et al seamlessly too.

Stable is a problem because a lot of these shells don’t offer any guarantees for breaking changes.

My own shell, https://github.com/lmorg/murex is committed to backwards compatibility but even here, there are occasional changes made that might break backwards compatibility. Though I do push back on such changes as much as possible, to the extent that most of my scripts from 5 years ago still run unmodified.

This is similar to how my shell works. It still just passes bytes around but additionally passes information about how those bytes could be interpreted. A schema if you will. So it works as cleanly with POSIX / GNU / et al tools as it does with fancy JSON, YAML, CSV and other document formats.

It basically sits somewhere between Powershell and Bash: typed pipelines like Powershell but without sacrificing familiarity with all the CLI commands you already use day in and day out.

As an aside, I’m about to drop a massive update in the next few days that will make the shell even more intuitive to use.
