javascript - How can I write a ESLint rule for "linebreak-style", changing depending on Windows or Unix? -

-

as know, linebreaks (new line) used in windows carriage returns (cr) followed line feed (lf) i.e. (crlf) whereas, linux , unix use simple line feed (lf)

now, in case, build server uses supports linux , unix format so, below rule working on build server:

linebreak-style: ["error", "unix"]

but doing development on windows , need update rule on each git pull/git push below,

linebreak-style: ["error", "windows"]

so, there way write generic linebreak-style rule support both environments, linux/unix , windows?

note: using ecmascript6[js], webstorm[ide] development

any solutions/suggestions highly appreciated. thanks!

the eslint configuration file can a regular .js file (ie, not json, full js logic) exports configuration object.

that means change configuration of linebreak-style rule depending on current environment (or other js logic can think of).

for example, use different linebreak-style configuration when node environment 'prod':

module.exports = {     "root": true,     "parseroptions": {         "sourcetype": "module",         "ecmaversion": 6     },     "rules": {         // windows linebreaks when not in production environment         "linebreak-style": ["error", process.env.node_env === 'prod' ? "unix" : "windows"]     } };

example usage:

$ node_env=prod node_modules/.bin/eslint src/test.js  src/test.js   1:25  error  expected linebreaks 'crlf' found 'lf'  linebreak-style   2:30  error  expected linebreaks 'crlf' found 'lf'  linebreak-style   3:36  error  expected linebreaks 'crlf' found 'lf'  linebreak-style   4:26  error  expected linebreaks 'crlf' found 'lf'  linebreak-style   5:17  error  expected linebreaks 'crlf' found 'lf'  linebreak-style   6:50  error  expected linebreaks 'crlf' found 'lf'  linebreak-style   7:62  error  expected linebreaks 'crlf' found 'lf'  linebreak-style   8:21  error  expected linebreaks 'crlf' found 'lf'  linebreak-style  ✖ 8 problems (8 errors, 0 warnings)  $ node_env=dev node_modules/.bin/eslint src/test.js $ # no errors
