# isexe
|
||||
|
||||
Minimal module to check if a file is executable, and a normal file.
|
||||
|
||||
Uses `fs.stat` and tests against the `PATHEXT` environment variable on
|
||||
Windows.
|
||||
|
||||
## USAGE
|
||||
|
||||
```js
|
||||
import { isexe, sync } from 'isexe'
|
||||
// or require() works too
|
||||
// const { isexe } = require('isexe')
|
||||
isexe('some-file-name').then(isExe => {
|
||||
if (isExe) {
|
||||
console.error('this thing can be run')
|
||||
} else {
|
||||
console.error('cannot be run')
|
||||
}
|
||||
}, (err) => {
|
||||
console.error('probably file doesnt exist or something')
|
||||
})
|
||||
|
||||
// same thing but synchronous, throws errors
|
||||
isExe = sync('some-file-name')
|
||||
|
||||
// treat errors as just "not executable"
|
||||
const isExe = await isexe('maybe-missing-file', { ignoreErrors: true })
|
||||
const isExe = sync('maybe-missing-file', { ignoreErrors: true })
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
### `isexe(path, [options]) => Promise<boolean>`
|
||||
|
||||
Check if the path is executable.
|
||||
|
||||
Will raise whatever errors may be raised by `fs.stat`, unless
|
||||
`options.ignoreErrors` is set to true.
|
||||
|
||||
### `sync(path, [options]) => boolean`
|
||||
|
||||
Same as `isexe` but returns the value and throws any errors raised.
|
||||
|
||||
## Platform Specific Implementations
|
||||
|
||||
If for some reason you want to use the implementation for a
|
||||
specific platform, you can do that.
|
||||
|
||||
```js
|
||||
import { win32, posix } from 'isexe'
|
||||
win32.isexe(...)
|
||||
win32.sync(...)
|
||||
// etc
|
||||
|
||||
// or:
|
||||
import { isexe, sync } from 'isexe/posix'
|
||||
```
|
||||
|
||||
The default exported implementation will be chosen based on
|
||||
`process.platform`.
|
||||
|
||||
### Options
|
||||
|
||||
```ts
|
||||
import type IsexeOptions from 'isexe'
|
||||
```
|
||||
|
||||
* `ignoreErrors` Treat all errors as "no, this is not
|
||||
executable", but don't raise them.
|
||||
* `uid` Number to use as the user id on posix
|
||||
* `gid` Number to use as the group id on posix
|
||||
* `pathExt` List of path extensions to use instead of `PATHEXT`
|
||||
environment variable on Windows.
