errno_converter & signal_converter & http_converter

As simple command line tool to convert error numbers (of C errno.h), signal numbers and HTTP-Status-Codes to human readable strings or back to numbers. This tool makes use of errno, signal and http module of Python 3.8 standard library (Python 3.8 added support for verbose signal descriptions).

Example usage of errno_converter:

$ errno_converter.py
./dev/errno_converter/errno_converter.py [-v] list|<errno-number>|<errno-name>

$ errno_converter.py ENOENT
2

$ errno_converter.py -v ENOENT
  2 - ENOENT         : No such file or directory

$ errno_converter.py 2
ENOENT

$ errno_converter.py -v 2
  2 - ENOENT         : No such file or directory

$ errno_converter.py ENOE
  2 - ENOENT
  8 - ENOEXEC

$ errno_converter.py -v ENOE
No errno matched the input 'ENOE' (module 'errno' has no attribute 'ENOE'). Try to match as re:
  2 - ENOENT         : No such file or directory
  8 - ENOEXEC        : Exec format error

$ errno_converter.py list
  1 - EPERM
  2 - ENOENT
…
130 - EOWNERDEAD
131 - ENOTRECOVERABLE

$ errno_converter.py -v list
  1 - EPERM          : Operation not permitted
  2 - ENOENT         : No such file or directory
…
130 - EOWNERDEAD     : Owner died
131 - ENOTRECOVERABLE: State not recoverable
invalids: {41, 58}

Example usage of signal_converter:

$ signal_converter.py
signal_converter.py [-v] list|<errno-number>|<errno-name>

$ signal_converter.py SIGINT
2

$ signal_converter.py -v SIGINT
  2 - SIGINT         : Interrupt

$ signal_converter.py 2
SIGINT

$ signal_converter.py -v 2
  2 - SIGINT         : Interrupt

$ signal_converter.py SIGIO.*
 29 - SIGIO
  6 - SIGIOT

~$ signal_converter.py -v SIGIO.*
No signal matched the input 'SIGIO.*' (module 'signal' has no attribute 'SIGIO.*'). Try to match as re:
 29 - SIGIO          : I/O possible
  6 - SIGIOT         : Aborted

$ signal_converter.py list
  1 - SIGHUP
  2 - SIGINT
…
 34 - SIGRTMIN
 64 - SIGRTMAX

$ signal_converter.py -v list
  1 - SIGHUP         : Hangup
  2 - SIGINT         : Interrupt
…
 34 - SIGRTMIN       : Real-time signal 0
 64 - SIGRTMAX       : Real-time signal 30
invalids: {16, 32, 33, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63}

Example .bashrc alias:

alias http_converter="python3 ~/errno_converter/http_converter.py"
