This is an implementation of various Unix common tools, as taught on 'Software Tools in Pascal' by Kernighan and Plauger. This is my interpretation of an Erlang implementation.
You need to compile ststd.erl first before trying
any tools as all of them will make heavy use of the
abstract functions for i/o such as getc and putc.
Indentation is made by a code formatter before any commit, if any file is lacking indentation I'm sorry, please notify me or you can make a PR.
There are redundant files.
Some tools can be found on stcN.erl files, where N is
the chapter number. Probably only chapters 1 and 2 will
provide such a monolith, since later on chapter 2 we start
to think about receive parameters and reusing tools with pipe,
so most or all of the programs from late chapter 2 onwards
will be executable escript files.
In those files there is a -compile(export_all) flag that
helps in testing functions of different arities.
Using a function from stcN packages inside repl means
entering the Input yourself on arity 0 functions, or
passing an Input on arity 1 functions.
Escript tools should accept both ststd:getc/1 for receiving data stream through pipes, and ststd:io/2 for files.
- revise tools to see if they're all accepting pipes
- translit still needs to implement
^(all but), and@(escape characters). Shouldn't be difficult but might need another approach other than using maps as data structure, it was a bad idea after all (the authors warned me!). - print (3.6 Multi-stage Processing: Pipelines)
- makecopy (3.7 Creating Files Dinamically)
- archive (3.8 Putting it All Together: archive)
- sorting methods (the entire chapter 4)
