gulp-splice v1.0.0
gulp-splice
Splices one file into another in a gulp pipeline.
Install
> npm install gulp-spliceUsage
The inner file is spliced into the outer file by replacing the first occurancy of the key in the outer file with the contents of the inner file:
outer.txt
This is outer file content.
<#key#>
This is outer file content.inner.txt
This is inner file content.var splice = require('gulp-splice');
gulp.src(['inner.txt','outer.txt']).pipe(splice('<#key#>'))outer.txt
This is outer file content.
This is inner file content.
This is outer file content.In the above, both files entered through the pipe. But you can also specify inner or outer files that do not enter through the pipe:
gulp.src('outer.txt').pipe(splice({key:'<#key#>', inner:'inner.txt'}))
gulp.src('inner.txt').pipe(splice({key:'<#key#>', outer:'outer.txt'}))
gulp.src().pipe(splice({key:'<#key#>', inner:'inner.txt', outer:'outer.txt' }))And all three produce the same result as the original:
outer.txt
This is outer file content.
This is inner file content.
This is outer file content.You can also send more than two files in through the pipe:
gulp.src('*.txt').pipe(splice('<#key#>'))In the absence of inner and outer options all non-outer files are concatinated to form a single inner file and spliced into the outer file, which is the first file that contains the key:
outer.txt
This is outer file content.
This is non-outer file 1 content.
This is non-outer file 2 content.
This is non-outer file 3 content.
...
This is outer file content.Adding an inner option disables the concatination of non-outer files, and all other files not involved in the splice are passed through:
gulp.src('*.txt').pipe(splice({key: '<#key#>', inner:'file1.txt'))outer.txt
This is outer file content.
This is file 1 content.
This is outer file content.file2.txt
...file3.txt
......API
splice('key')
splice(options)options.key : string
The key is a string that identifies the insertion point in the outer file. Only the first occurance in the outer file is replaced with the contents of the inner file.
options.outer : string
If the outer option is present, the outer file is the file specified by the option. If the file arrives down the pipe it is plucked from the file stream, otherwise it is opened from the file system. If the outer option is absent, the outer file is the first file arriving down the pipe that contains the key.
options.inner : string
If the inner option is present, the inner file is the file specified by the option. If the file arrives down the pipe it is plucked from the file stream, otherwise it is opened from the file system. If the inner option is absent, all non-outer files ariving down the pipe are concatinated to form the inner file.
Example
Here's an example that inlines HTML view templates into the bottom of the index.html:
index.html
<html>
<body>
<h1>Main</h1>
##views##
</body>
</html>partial-A.html
<h1>View A</h1>partial-B.html
<h1>View B</h1>partial-C.html
<h1>View C</h1>gulp.src('*.html')
.pipe(htmlmin())
.pipe(splice('##views##'))
.dest('dist/')dist/index.html
<html><body><h1>Main</h1><h1>View A</h1><h1>View B</h1><h1>View C</h1></body></html>Test
