webpack-sources
Contains multiple classes which represent a Source
. A Source
can be asked for source code, size, source map and hash.
Source
Source
Base class for all sources.
Public methods
All methods should be considered as expensive as they may need to do computations.
source
source
Returns the represented source code as string.
size
size
Returns the size in chars of the represented source code.
map
map
Returns the SourceMap of the represented source code as JSON. May return null
if no SourceMap is available.
The options
object can contain the following keys:
columns: Boolean
(defaulttrue
): If set to false the implementation may omit mappings for columns.module: Boolean
(defaulttrue
): If set to false the implementation may omit inner mappings for modules.
sourceAndMap
sourceAndMap
Returns both, source code (like Source.prototype.source()
and SourceMap (like Source.prototype.map()
). This method could have better performance than calling source()
and map()
separately.
See map()
for options
.
updateHash
updateHash
Updates the provided Hash
object with the content of the represented source code. (Hash
is an object with an update
method, which is called with string values)
node
(optional)
node
(optional)This is an optional method. It may be null
if not implemented.
Returns a SourceNode
(see source-map library) for the represented source code.
See map()
for options
.
listNode
(optional)
listNode
(optional)This is an optional method. It may be null
if not implemented.
Returns a SourceListMap
(see source-list-map library) for the represented source code.
See map()
for options
.
RawSource
RawSource
Represents source code without SourceMap.
OriginalSource
OriginalSource
Represents source code, which is a copy of the original file.
sourceCode
: The source code.name
: The filename of the original source code.
OriginalSource tries to create column mappings if requested, by splitting the source code at typical statement borders (;
, {
, }
).
SourceMapSource
SourceMapSource
Represents source code with SourceMap, optionally having an additional SourceMap for the original source.
sourceCode
: The source code.name
: The filename of the original source code.sourceMap
: The SourceMap for the source code.originalSource
: The source code of the original file. Can be omitted if thesourceMap
already contains the original source code.innerSourceMap
: The SourceMap for theoriginalSource
/name
.removeOriginalSource
: Removes the source code forname
from the final map, keeping only the deeper mappings for that file.
The SourceMapSource
supports "identity" mappings for the innerSourceMap
. When original source matches generated source for a mapping it's assumed to be mapped char by char allowing to keep finer mappings from sourceMap
.
LineToLineMappedSource
LineToLineMappedSource
Represents source code, which is mapped line by line to the original file.
sourceCode
: The source code.name
: The filename of the original source code.originalSource
: The original source code.
CachedSource
CachedSource
Decorates a Source
and caches returned results of map
, source
, size
and sourceAndMap
in memory. Every other operation is delegated to the wrapped Source
.
PrefixSource
PrefixSource
Prefix every line of the decorated Source
with a provided string.
ConcatSource
ConcatSource
Concatenate multiple Source
s or strings to a single source.
Public methods
add
add
Adds an item to the source.
ReplaceSource
ReplaceSource
Decorates a Source
with replacements and insertions of source code.
The ReplaceSource
supports "identity" mappings for child source. When original source matches generated source for a mapping it's assumed to be mapped char by char allowing to split mappings at replacements/insertions.
Public methods
replace
replace
Replaces chars from start
(0-indexed, inclusive) to end
(0-indexed, inclusive) with replacement
.
Locations represents locations in the original source and are not influenced by other replacements or insertions.
insert
insert
Inserts the insertion
before char pos
(0-indexed).
Location represents location in the original source and is not influenced by other replacements or insertions.
original
original
Get decorated Source
.
