Universal Code Formatter
A code formatter that formats any code.
Install
With cargo
cargo install ucf
Arch linux
ucf is available in the aur here. With an aur helper like yay, it can be installed with
yay -S ucf
Usage
ucf <file_name>
Caution: ucf modifies the file in place and there is no option to output to stdout at the moment.
ucf --help
prints help.
Inner working
ucf is a simple program. It determines the file extension and calls a predetermined code formatter on the file as listed in the table below with necessary arguments to modify the file in place. The formatter called should be present in the system's PATH.
Currently used formatters
| Formatter called | File Extension |
|---|---|
| black | .py |
| clang-format | .c, .cpp, .cc, .cs, .cxx, .cp, .cs, .h, .hpp, .hxx .java, .json, .m (objective c, not matlab) |
| cmake-format | .cmake |
| gofmt | .go |
| ocamlformat | .ocaml |
| prettier | .css, .gfm, .graphql, .gql, .html, .js, .jsx, .less, .md, .mdx, .prettierrc, .sass, .scss, .svelte, .ts, .vue, .yaml |
| rustfmt | .rs |
| shfmt | .sh, .ebuild |
| stylua | .lua |
| stylish-haskell | .hs |
| taplo | .toml |
| xmllint | .xml |
| zig fmt | .zig |
Editor Integration
vim / neovim
After saving the file, run ucf on the file as a shell command.
:!ucf %
This can be automated in many ways, eg. To bind <F5> to save and format the file, add the following line in init.lua,
vim.keymap.set('n', '<F5>', ':w | :!ucf % <CR><CR>', {noremap=true, silent=true})
Config file
To ignore certain file extensions, add the extensions without the dot in the ignored_extensions array in $XDG_CONFIG_HOME/ucf/config.toml file. ucf formats code overriding the config file if a custom formatter is given.
Todo
- Add option to read folders and run formatter on all files
- Add option to format
SQL - Display proper error messages (bug)
For packagers
If you would like to package ucf for any distro, make sure to add the packages which provide the binaries from the table above as optional dependencies.
