SQLiteStudio
A free, open source, multi-platform SQLite database manager
A free, open-source, multi-platform SQLite database manager written in C++, with use of Qt framework. It's free of charge for everybody, for any purpose (including commercial). It's safe, as anyone can review the source code. The SQL Editor window assists users with SQL syntax hints & highlighting, provides pretty-print code formatter, and marks syntax errors. You can Ctrl+click on the table mentioned in the SQL query to open that table (or index, or trigger, or view). Currently supported encrypted, password-protected SQLite variations are SQLCipher, WxSQLite3, and System.Data.SQLite. You can execute SQL statements that refer to multiple databases within a single query, thanks to a transparent database attaching mechanism built into the SQL Editor of SQLiteStudio. You can implement your own SQL functions (scalar & aggregate) using JavaScript, Python, or Tcl. There is a repository of ready-to-use scripts on the wiki page. -

fmt
Formatting library as an alternative to C stdio and C++ iostreams
{fmt} is an open-source formatting library providing a fast and safe alternative to C stdio and C++ iostreams. The format API is similar in spirit to the C printf family of function but is safer, simpler and several times faster than common standard library implementations. The format string syntax is similar to the one used by str.format in Python. The library is fully type safe, automatic memory management prevents buffer overflow, errors in format strings are reported using exceptions or at compile time. The library produces compact per-call compiled code. The library is highly portable and relies only on a small set of C++11 features, like variadic templates, type traits, rvalue references, decltype, trailing return, types, deleted functions, alias templates. These are available in GCC 4.8, Clang 3.0, MSVC 19.0 (2015) and more recent compiler version. For older compilers use {fmt} version 4.x which is maintained and only requires C++98. -

Prettier Formatter for Visual Studio
Visual Studio Code extension for Prettier
Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary. To ensure that this extension is used over other extensions you may have installed, be sure to set it as the default formatter in your VS Code settings. This setting can be set for all languages or by a specific language. If you want to disable Prettier on a particular language you can either create a .prettierignore file or you can use VS Code's editor.defaultFormatter settings. Additionally, you can disable format on save for specific languages if you don't want them to be automatically formatted. This extension will use prettier from your project's local dependencies (recommended). When the prettier.resolveGlobalModules is set to true the extension can also attempt to resolve global modules. -

StyLua
An opinionated Lua code formatter
An opinionated code formatter for Lua 5.1, 5.2, 5.3, 5.4 and Luau, built using full-moon. StyLua is inspired by the likes of prettier, it parses your Lua codebase, and prints it back out from scratch, enforcing a consistent code style. By default, these are built with all syntax variants enabled (Lua 5.2, 5.3, 5.4 and Luau), to cover all possible codebases. If you would like to format a specific Lua version only, see installing from crates.io. You can use the stylua-action GitHub Action in your CI to install and run StyLua. This action uses the prebuilt GitHub release binaries, instead of running cargo install, for faster CI times. This command will format the foo.lua and bar.lua file, and search down the src directory to format any files within it. StyLua can also read from stdin, by using - as the file name. -

Vim Codefmt
Vim plugin for syntax-aware code formatting
vim-codefmt is a syntax-aware code formatting plugin for Vim that provides a unified interface to many best-in-class formatters across languages. It exposes simple commands to format either a selected range or an entire buffer, and integrates cleanly into everyday editing workflows. The plugin ships with a registry of built-in formatters and a pluggable architecture, allowing other plugins to register additional formatters without friction. Configuration is handled through maktaba and Glaive flags, so you can choose per-filetype tools, pass custom options, or point to specific formatter executables. Autoformat can be enabled via standard Vim autocommands, making it easy to format on filetype or on write while still allowing opt-out on a per-buffer basis. With broad language coverage—from C, C++, Java, Python, and Go to Kotlin, Rust, Swift, Bazel, Markdown, and more—vim-codefmt helps teams maintain consistent style across heterogeneous codebases. -
