env-cmd/CHANGELOG.md

Executes a command using the environment variables in an env file

# Changelog

## 10.1.0

- **Feature**: Added support for expanding vars using the `-x` flag. 
Note: only supports `$var` syntax
- **Feature**: Added support for `--silent` flag that ignores env-cmd errors and missing files and 
only terminates on caught signals
- **Feature**: Added a new `--verbose` flag that prints additional debugging info to `console.info`
- **Upgrade**: Updated dependency `commander` to `v4`
- **Upgrade**: Updated devDependencies `sinon`, `nyc`, and `ts-standard`
- **Fix**: Handle case where the termination signal is the termination code

## 10.0.1

- **Fix**: Fixed bug introduced by strict equal checking for `undefined` when the value was `null`. This
bug caused most executions of `env-cmd` to fail with an error, when in fact no error had occurred.

## 10.0.0

- **BREAKING**: Typescript now targets ES2017
- **Fix**: Default RC files will now properly be searched
- **Change**: Fixed some documentation issues
- **Change**: Use `ts-standard` instead of `eslint` for linting

## 9.0.3

- **Fix**: Use global flag on regex when parsing and preserving newline characters in env values (thanks to MaximTovstashev)

## 9.0.2

- **Fix**: CLI will now exit with non-zero error code when an error is encountered (thanks to blagh)

## 9.0.1

- **BREAKING**: Fixed major bug that required passing `--` in order to pass flags to the command.
Normally I release major breaking changes as major versions, but this was a bug and no documentation
anywhere states using `--` as intended or official behavior.
- **Change**: Fixed some documentation issues
- **Change**: `npm run lint` command now includes calling `tsc` to check for typescript errors

## 9.0.0

- ***BREAKING***: Converted project to Typescript
- ***BREAKING***: Changes to all option flags, see docs for new options
- ***BREAKING***: Dropping support for node v4 and v6
- **Change**: Updated all dependencies
- **Change**: Update package-lock.json file
- **Feature**: Added support for asynchronous .env and .rc files
- **Feature**: Added support for a programmatic API
- **Feature**: Added --use-shell option (thanks to nidkil)
- **Fix**: Keep newline (`\n`) characters intact when parsing env files
- **Change**: Added node v10 and v12 to build automation
- **Change**: Updated Readme file to reflect new options and CLI changes

## 8.0.2

- **Change**: Updated dependencies and packages.json to fix `npm audit` concerns.

## 8.0.1

- **Bug**: Properly propagate child process exit signals and codes to parent process

## 8.0.0

- ***BREAKING***: Stripe out spaces around the `key` and `value` in an env file. In order to include a beginning/ending space in an env var value, you need to surround the value in double or single quotes. `ENV = " Value"`
- **Bug**: Fixed some bugs around how the parent process and spawn processes are killed
- **Change**: Updated a number of core libraries: `cross-spawn`, `coveralls`, `istanbul -> nyc`, `mocha`, `proxyquire`, `sinon`, `standard`

## 7.0.0

- ***BREAKING***: The `.env` file path resolving has been changed to allow for absolute pathing, relative pathing, and `~` home directory pathing. Please
see Readme.md for more info about how the new pathing conventions work.

## 6.0.0

- ***BREAKING***: Fallback to default `.env` file behavior is no longer the default behavior. You must specify `--fallback` option for that behavior now.
- ***BREAKING***: A specific node version has been set in package.json. Current minimum version is `>=4.0.0`. *Note: the implied minimum version
before this release was always `4.0.0`, but now it is explicitly set and could produce warnings by npm if included in projects that utilizes a
node version that is less than `4.0.0`.*
- **Feature**: Added `--fallback` option to allow for falling back to the default `.env` file if the provided `.env` file is not found.
- **Feature**: Added ability to select multiple environments from the `.env-cmdrc` file. The environments override each other like this:
`development,production` where `production` vars override `development` vars if they share the same vars.
- **Bug**: `env-cmd` no longer crashes when it cannot find the provided `.env` file. Instead, it will execute as normal, but without included any custom env vars. *Note: it will still include system and shell vars.*

## 5.1.0

- **Feature**: Added new option `--no-override` that when passed will make it so that the env file
vars will not overwrite already defined env vars on `process.env` or in the shell
- **Updated Dev-Dependencies**: `standard >= 10.0.0`, `sinon >= 2.0.0`

## 5.0.0

- ***BREAKING***: Inline comments are no longer allowed in `.env` files (full line comments are still allowed)
- ***BREAKING***: `.env` file no longer supports the `env var` format (only `env=var` is allowed now)
- ***BREAKING***: Double Quotes are no longer needed when using special symbols (such as `#`) in the value portion of an env var
- **Feature**: if the given env file cannot be found, it will auto default to searching
the execution directory for a file called `.env` and use that as a fallback. See README for why this is
helpful. (special thanks to Alexander Praetorius)

## 4.0.0

- ***BREAKING***: In order to use double quotes as part of the env value, you must now surround those double quotes with an additional set of quotes: So `ENV1="value"` -> `ENV1=""value""` (this only applies to double quotes, single quotes continue to work as normal)
- **Bug**: Fixed bug in the comment stripper function that would remove env values that included a `#`. Now, in order to use a `#` in a env value, you have to surround that env value in double quotes: `ENV="Some#Value"`.
- **Bug**: Fixed a major bug with the `.env-cmdrc` file that would not add system env vars back in after reading the `.env-cmdrc` file. This meant that system vars like `PATH` would not exist when running the command.

## 3.0.0

- **Feature**: Added ability to use an `.env-cmdrc` file to hold multiple configs
- **Feature**: Added ability to pass in a regular `.js` file exporting an object for your env file (special thanks to Jon Scheiding!)
- **Change**: Updated core `cross-spawn` lib to 5.0.1

## 2.2.0

- **Feature**: Added support for .json env files (special thanks to Eric Lanehart!)

## 2.1.0

- **Feature**: Added support for `key value` mapping in env vars file
- **Feature**: Added support for inline comments `ENV=VALUE # inline comment`
- **Change**: Will now ignore invalid lines in env vars file instead of throwing an error
- **Change**: Migrated all the parsing over to regex since the file format is simple enough right
now to support that
- **Bug**: Removed old test cases for the `-e/--env` flags that were not needed anymore

## 2.0.0

- ***BREAKING***: Removed the `-e` and `--env` flags. Now it just expects the first arg to `env-cmd` to be the relative path to the env file: `env-cmd env_file command carg1 carg2`
- **Change:** `ParseEnvFile` is now more properly named `ParseEnvString`
- **Feature:** `ParseEnvString` will ignore comment lines (lines starting with `#`)
- **Feature:** `ParseEnvString` will ignore empty lines in env file
- **Bug:** `ParseEnvString` will extract the last line even if no newline (`\n`) exists on it

## 1.0.1

- Fixed badges
- Added .npmignore
- Added help text to be printed out on certain errors
- Handled uncaught errors nicely

## 1.0.0
