    TortoiseSVN

    TortoiseSVN

    PyInstaller

    PyInstaller

    Freeze (package) Python programs into stand-alone executables

    PyInstaller freezes (packages) Python applications into stand-alone executables, under Windows, GNU/Linux, Mac OS X, FreeBSD, Solaris and AIX. PyInstaller’s main advantages over similar tools are that PyInstaller works with Python 3.5 to 3.9, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and use the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You’ll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. As an example, libraries like PyQt, Django or matplotlib are fully supported, without having to handle plugins or external data files manually.

    ConEmu - Handy Console Window

    ConEmu - Handy Console Window

    Local Terminal Emulator

    ConEmu-Maximus5 aims to be handy, comprehensive, fast and reliable terminal window where you may host any console application developed either for WinAPI (cmd, powershell, far) or Unix PTY (cygwin, msys, wsl bash). As Windows console window enhancement (local terminal emulator), it presents multiple consoles and simple GUI applications as one customizable tabbed GUI window with various features. Also, due to deep integration, ConEmu is the best companion for Far Manager, my favorite shell replacement. Disclaimer. ConEmu is not a shell, so it does not provide "shell features" like tab-completion, command history and others. But you can run any shell or remote access client of your choice in ConEmu! Try Clink for bash-style completion in cmd.exe and PSReadLine or PowerTab in powershell.exe. Or just run Bash from your favourite distro. Also, ConEmu does not provide remote access (SSH/Telnet/...) too, just use your remote client (ssh.exe, telnet.exe) instead.

    pl

    Perl One-Liner Magic Wand

    Some tasks are too menial for a dedicated script but still too cumbersome even with the many neat one-liner options of "perl -E". This small script fills the gap: various one-letter commands & magic variables (with meaningful aliases too) and more nifty loop options take Perl programming to the command line. Fully imports List::Util. With no program on the command line, starts a pl Shell. How to "e(cho)" values, including from "@A(RGV)", with single "$q(uote)" & double "$Q(uote)". Same for hard-to-print values: $  pl  'e  "${q}Perl$q",  "$Q@A$Q"'  one-liner $  pl  'e  \"Perl",  \@A,  undef'  one-liner Loop over args, printing each with line ending.  And same, SHOUTING: $  pl  -opl  ''  Perl  one-liner $  pl  -opl  '$_  =  uc'  Perl  one-liner Print up to 3 matching lines, resetting count (and "$.") for each file: $  pl  -rP3  '/Perl.*one.*liner/'  file* Count hits in magic statistics hash "%N(UMBER)": $  pl  -n  '++$N{$1}  while  /(Perl|one|liner)/g'  file*
