* run prettier * initial sourcemap * improve sourcemap constructor * also support SourceMapConsumer as addMap input * some cleanup and fixes * add lineOffset and 1:1 sourcemaps * add lineOffset and 1:1 sourcemaps * slight sourcemaputil improvement * use babel-generator instead of double generating * add 1:1 sourcemap for untranspiled assets * update offset * fix source paths * Better offset solution * fix sourceContent not being set by babel-generator * fix small offset bug * add sourcemap option and offset when globals are added * add cli option to disable sourcemaps * ts & coffeescript support * fix most tests * All tests (except hmr) fixed + bugfix for ts * fix hmr tests * comment out error throwing in tests * fix windows tests * add sourcemap tests * add comment to why throwing errors is commented out in tests * update with circular fix, now throws on test failures * fix generator for invalid maps * fix tests * fix tiny issues * small performance improvement * rewrite sourcemap handling, less generator constructing overhead and some more improvements * extendSourceMap bugfix * Use babel rawMappings to remove encoding step * small performance fixes * improve linecounter * small performance improvement and bugfix * small improvement * change for source-map 0.7 compatibility, improves performance a lil * switch to official npm release * tiny improvement * only install source-map 0.7 if possible * remove optional 0.7 dep * Minor refactorings * Store precomputed line count as part of source map * Clean up * Last cleanup
