editorconfig-tools
This tool-set is for validating or fixing code that doesn't adhere to settings defined in .editorconfig
. It also is able to infer settings from existing code and generate an .editorconfig
file that matches all the files that are passed to it. See the EditorConfig Project for details about the .editorconfig
file.
CLI
The CLI is (currently) the only way of using editorconfig-tools. The following sections detail the 3 subcommands that editorconfig-tools provides.
infer
Infer .editorconfig
settings from one or more files and generate an .editorconfig
file that matches all the files that are passed to it.
Here's an example using the files from this project. It is assumed that you have globstar enabled in your shell. While editorconfig-tools itself doesn't require it, these examples do use it to pass whole directories of files to editorconfig-tools.
$ editorconfig-tools infer ./* ./lib/**/* ./test/**/*
[*]
end_of_line = lf
indent_style = space
indent_size = 2
insert_final_newline = true
max_line_length = 80
trim_trailing_whitespace = true
[{./test/fixtures/end-of-line/file}]
end_of_line = crlf
[{./Makefile,./test/fixtures/indent-char-tab/file}]
indent_style: tab
[{./test/fixtures/insert-final-newline-false/file}]
insert_final_newline = false
As you can see, a set of rules has been generated that matches all of the files that we passed in. If we were making an .editorconfig
file for a project that doesn't already have one, we might want to write this out to a file:
$ editorconfig-tools infer ./* ./lib/**/* ./test/**/* > .editorconfig
We would still probably want to add root = true
to the file (if this is saved at the root of the project), but editorconfig-tools has done most of the work required to make an .editorconfig
file.
check
Check (validate) that file(s) adhere to .editorconfig
settings and return a non-zero exit code if errors are encountered (making it suitable for running as a test). For example, if we added some trailing whitespace to our readme, this would be the result:
$ editorconfig-tools check README.md
README.md failed trim_trailing_whitespace on line 46: found setting 'false', should be 'true'
fix
Fix formatting errors that disobey .editorconfig
settings. This will modify your files without warning, so you should ensure that your project is under version control before running it.
For example, if we write a file with 4-space indentation, and then run the fix command (using the settings of this particular project) we will get back a 2-space indented file:
$ echo -e 'line one\n line two' > example-file
$ editorconfig-tools fix ./example-file
$ cat example-file
line one
line two
