jscc's Issues

link request

I created a gulp plugin for jscc, could you please add a link in doument ?

Use with imports

Hi

I was trying to do something like:

import thing from '../my-thing.js';

//#set _FOO = thing.object[key]

But am getting `thing is not defined in expression "thing.object[key]".
Is it possible to make this work?

Webpack plugin

Thank you for all your hard work. Any chance of a webpack plugin?

Browserify plugin

This is really cool! Any chance for a browserify plugin? I'd like to use jscc within budo during development which uses browserify under the hood.

Error: Invalid regular expression

Single line directives capture the comment ending token as part of the expression.

/* #if process.env.TARGET === 'chrome' */

Error: Invalid regular expression: missing / in expression "process.env.TARGET === 'chrome' */"

For languages such as css that don't have single line comments this means that directions must be two lines.

/* #if process.env.TARGET === 'chrome'
*/

not work with eslint rule: comma-spacing

eslint will insert spacing after // and /*

// #set _DEBUG = 1           // this is a jscc comment

/* #if _DEBUG                // closing this multiline comment */
    // #if process.env.devmode === 'production'
    // #set _DEBUG 0         // the `=` is optional
    // #else                 anything after `#else` or `#endif` is ignored
/* eslint-disable no-console */
console.log('Debug mode on.');
    // #endif
// #endif _DEBUG             '_DEBUG' is ignored

So, jscc could not work.

what about a more complex "if" ?

I have many of the lines below:

//#if _JSCC__BUNDLE_FOO || _JSCC__BUNDLE_ALL
import foo  from './controllers/foo';
//#endif
//#if _JSCC__BUNDLE_BAR || _JSCC__BUNDLE_ALL
import bar  from './controllers/bar';
//#endif
//#if _JSCC__BUNDLE_BAZ || _JSCC__BUNDLE_ALL
import baz  from './controllers/baz';
//#endif

I use Rollup and I want the user to control if each component should or should be loaded individually or simply allow all of them to be bundled. I saw no mention of this in the WIKI.

Also, why is the //#endif needed? can you make so if it is omitted then only the code line directly below the if is taken into account?

Thanks!

Removel of trailing jscc comment is breaking the expression

Two slashes within a literal regex or ES6 TL will break jscc expressions:

//#set _R = /\///
//#set _S = `//`

This is because the parser confuses the slashes in the content with the trailing comment.
