    TortoiseSVN

    TortoiseSVN

    An Apache SVN client, right where you need it most

    TortoiseSVN is a Subversion (SVN) client, implemented as a windows shell extension. Which means it's available right where you need it: in the Windows file explorer. It's intuitive and easy to use, since it doesn't require the Subversion command line client to run. Simply the coolest Interface to (Sub)Version Control!

    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.

    EDITEL

    EDITEL is a screen editor/code generator for GnuCOBOL programmers

    One of the hardest things to do when coding with COBOL is translating a screen design into code. The process may take hours, not to say days. In my old BLIS-COBOL, COBOL 74 and COBOL 80 /85 days (and those last 2 had the SCREEN SECTION which helped a lot !), I recall spending a significant amount of time dedicated to that activity. Time that could be used for more productive activities like coding and resolving bugs, for instance. Having said that, I developed a Screen Editor (similar to a Screen Painter, as some tools may call it) which allows the user to create screen layouts (which includes the use of colors) with delimited fields and respective input masks, and finally generate the SCREEN SECTION code that reflects that layout. All of it automatically - no code needed. The idea came from a program I used to use named EDITEL. I have adapted the concept (it was originally built for BLIS COBOL systems) and created a version that does this for GnuCOBOL and Microfocus COBOL. Enjoy !
