+# loose-envify
+
+[![Build Status](https://travis-ci.org/zertosh/loose-envify.svg?branch=master)](https://travis-ci.org/zertosh/loose-envify)
+
+Fast (and loose) selective `process.env` replacer using [js-tokens](https://github.com/lydell/js-tokens) instead of an AST. Works just like [envify](https://github.com/hughsk/envify) but much faster.
+
+## Gotchas
+
+* Doesn't handle broken syntax.
+* Doesn't look inside embedded expressions in template strings.
+  - **this won't work:**
+  ```js
+  console.log(`the current env is ${process.env.NODE_ENV}`);
+  ```
+* Doesn't replace oddly-spaced or oddly-commented expressions.
+  - **this won't work:**
+  ```js
+  console.log(process./*won't*/env./*work*/NODE_ENV);
+  ```
+
+## Usage/Options
+
+loose-envify has the exact same interface as [envify](https://github.com/hughsk/envify), including the CLI.
+
+## Benchmark

+
+  $ for i in {1..5}; do node bench/bench.js 'envify'; done

+### Version 1.0.3 (2016-03-27) ###
+
+- Improved: Made the regex ever so slightly smaller.
+- Updated: The readme.
+
+
+### Version 1.0.2 (2015-10-18) ###
+
+- Improved: Limited npm package contents for a smaller download. Thanks to
+  @zertosh!
+
+
+### Version 1.0.1 (2015-06-20) ###
+
+- Fixed: Declared an undeclared variable.
+
+
+### Version 1.0.0 (2015-02-26) ###
+
+- Changed: Merged the 'operator' and 'punctuation' types into 'punctuator'. That
+  type is now equivalent to the Punctuator token in the ECMAScript
+  specification. (Backwards-incompatible change.)
+- Fixed: A `-` followed by a number is now correctly matched as a punctuator
+  followed by a number. It used to be matched as just a number, but there is no
+  such thing as negative number literals. (Possibly backwards-incompatible
+  change.)
+
+
+### Version 0.4.1 (2015-02-21) ###
+
+- Added: Support for the regex `u` flag.
+
+
+### Version 0.4.0 (2015-02-21) ###
+
+- Improved: `jsTokens.matchToToken` performance.
+- Added: Support for octal and binary number literals.
+- Added: Support for template strings.
+
+
+### Version 0.3.1 (2015-01-06) ###
+
+- Fixed: Support for unicode spaces. They used to be allowed in names (which is
+  very confusing), and some unicode newlines were wrongly allowed in strings and
+  regexes.
+
+
+### Version 0.3.0 (2014-12-19) ###
+
+- Changed: The `jsTokens.names` array has been replaced with the
+  `jsTokens.matchToToken` function. The capturing groups of `jsTokens` are no
+  longer part of the public API; instead use said function. See this [gist] for
+  an example. (Backwards-incompatible change.)
+- Changed: The empty string is now considered an “invalid” token, instead an
+  “empty” token (its own group). (Backwards-incompatible change.)
+- Removed: component support. (Backwards-incompatible change.)
+
+[gist]: https://gist.github.com/lydell/be49dbf80c382c473004
+
+
+### Version 0.2.0 (2014-06-19) ###
+
+- Changed: Match ES6 function arrows (`=>`) as an operator, instead of its own
+  category (“functionArrow”), for simplicity. (Backwards-incompatible change.)
+- Added: ES6 splats (`...`) are now matched as an operator (instead of three
+  punctuations). (Backwards-incompatible change.)
+
+
+### Version 0.1.0 (2014-03-08) ###

+Overview [![Build Status](https://travis-ci.org/lydell/js-tokens.png?branch=master)](https://travis-ci.org/lydell/js-tokens)
+========
+
+A regex that tokenizes JavaScript.
+
+```js
+var jsTokens = require("js-tokens")
+
+var jsString = "var foo=opts.foo;\n..."
+
+jsString.match(jsTokens)
+// ["var", " ", "foo", "=", "opts", ".", "foo", ";", "\n", ...]
+```
+
+
+Installation
+============
+
+`npm install js-tokens`
+
+```js
+var jsTokens = require("js-tokens")
+```
+
+
+Usage
+=====
+
+### `jsTokens` ###
+
+A regex with the `g` flag that matches JavaScript tokens.
+
+The regex _always_ matches, even invalid JavaScript and the empty string.
+
+The next match is always directly after the previous.
+
+### `var token = jsTokens.matchToToken(match)` ###
+
+Takes a `match` returned by `jsTokens.exec(string)`, and returns a `{type:
+String, value: String}` object. The following types are available:
+
+- string
+- comment
+- regex
+- number
+- name
+- punctuator
+- whitespace
+- invalid
+
+Multi-line comments and strings also have a `closed` property indicating if the
+token was closed or not (see below).
+
+Comments and strings both come in several flavors. To distinguish them, check if
+the token starts with `//`, `/*`, `'`, `"` or `` ` ``.
+
+Names are ECMAScript IdentifierNames, that is, including both identifiers and
+keywords. You may use [is-keyword-js] to tell them apart.
+
+Whitespace includes both line terminators and other whitespace.
+
+For example usage, please see this [gist].
+
+[is-keyword-js]: https://github.com/crissdev/is-keyword-js
+[gist]: https://gist.github.com/lydell/be49dbf80c382c473004
+
+
+ECMAScript support
+==================
+
+The intention is to always support the latest stable ECMAScript version.
+
+If adding support for a newer version requires changes, a new version with a
+major verion bump will be released.
+
+Currently, [ECMAScript 2015] is supported.
+
+[ECMAScript 2015]: http://www.ecma-international.org/ecma-262/6.0/index.html
+
+
+Invalid code handling
+=====================
+
+Unterminated strings are still matched as strings. JavaScript strings cannot
+contain (unescaped) newlines, so unterminated strings simply end at the end of
+the line. Unterminated template strings can contain unescaped newlines, though,
+so they go on to the end of input.
+
+Unterminated multi-line comments are also still matched as comments. They
+simply go on to the end of the input.
+
+Unterminated regex literals are likely matched as division and whatever is
+inside the regex.
+
+Invalid ASCII characters have their own capturing group.
+
+Invalid non-ASCII characters are treated as names, to simplify the matching of
+names (except unicode spaces which are treated as whitespace).
+
+Regex literals may contain invalid regex syntax. They are still matched as
+regex literals. They may also contain repeated regex flags, to keep the regex
+simple.
+
+Strings may contain invalid escape sequences.
+
+
+Limitations
+===========
+
+Tokenizing JavaScript using regexes—in fact, _one single regex_—won’t be
+perfect. But that’s not the point either.
+
+You may compare jsTokens with [esprima] by using `esprima-compare.js`.
+See `npm run esprima-compare`!
+
+[esprima]: http://esprima.org/
+
+### Template string interpolation ###
+
+Template strings are matched as single tokens, from the starting `` ` `` to the
+ending `` ` ``, including interpolations (whose tokens are not matched
+individually).
+
+Matching template string interpolations requires recursive balancing of `{` and
+`}`—something that JavaScript regexes cannot do. Only one level of nesting is
+supported.
+
+### Division and regex literals collision ###
+
+Consider this example:
+
+```js
+var g = 9.82
+var number = bar / 2/g
+
+var regex = / 2/g
+```
+
+A human can easily understand that in the `number` line we’re dealing with
+division, and in the `regex` line we’re dealing with a regex literal. How come?
+Because humans can look at the whole code to put the `/` characters in context.
+A JavaScript regex cannot. It only sees forwards.
+
+When the `jsTokens` regex scans throught the above, it will see the following
+at the end of both the `number` and `regex` rows:
+
+```js
+/ 2/g
+```
+
+It is then impossible to know if that is a regex literal, or part of an
+expression dealing with division.
+
+Here is a similar case:
+
+```js
+foo /= 2/g
+foo(/= 2/g)
+```
+
+The first line divides the `foo` variable with `2/g`. The second line calls the
+`foo` function with the regex literal `/= 2/g`. Again, since `jsTokens` only
+sees forwards, it cannot tell the two cases apart.
+
+There are some cases where we _can_ tell division and regex literals apart,
+though.
+
+First off, we have the simple cases where there’s only one slash in the line:
+
+```js
+var foo = 2/g
+foo /= 2
+```
+
+Regex literals cannot contain newlines, so the above cases are correctly
+identified as division. Things are only problematic when there are more than
+one non-comment slash in a single line.
+
+Secondly, not every character is a valid regex flag.
+
+```js
+var number = bar / 2/e
+```
+
+The above example is also correctly identified as division, because `e` is not a
+valid regex flag. I initially wanted to future-proof by allowing `[a-zA-Z]*`
+(any letter) as flags, but it is not worth it since it increases the amount of
+ambigous cases. So only the standard `g`, `m`, `i`, `y` and `u` flags are
+allowed. This means that the above example will be identified as division as
+long as you don’t rename the `e` variable to some permutation of `gmiyu` 1 to 5
+characters long.
+
+Lastly, we can look _forward_ for information.
+
+- If the token following what looks like a regex literal is not valid after a
+  regex literal, but is valid in a division expression, then the regex literal
+  is treated as division instead. For example, a flagless regex cannot be
+  followed by a string, number or name, but all of those three can be the
+  denominator of a division.
+- Generally, if what looks like a regex literal is followed by an operator, the
+  regex literal is treated as division instead. This is because regexes are
+  seldomly used with operators (such as `+`, `*`, `&&` and `==`), but division
+  could likely be part of such an expression.
+
+Please consult the regex source and the test cases for precise information on
+when regex or division is matched (should you need to know). In short, you
+could sum it up as:
+
+If the end of a statement looks like a regex literal (even if it isn’t), it
+will be treated as one. Otherwise it should work as expected (if you write sane
+code).
