Brute Force id uglifier
id-uglifier is a 2-pass brute force code uglifier.
It works based on the raw assumption that every identifier that ends
with _UG is subject to uglification. It also accepts a table of identifiers to be uglified.
id-uglifier is language agnostic and not only uglifies source code but also
css, html, text and whatever you feed it.
In essence, you provide it a file tree and it will generate and output file tree
where every id that matches a pattern will be replace with ug_NNNN.
At first glance, it might look like that it’s too blind for industrial-strength projects,
but the probability of running into an external library where the ids end with _UG is very low.
And, if such case occurs, id-uglifier allows to define another id suffix.
id-uglifier isn’t built for existing projects, but instead of projects
where the business logic is prepared from inception for id uglification,
the extra prefix will give clues to the developers that
that id will be changed in the final output.
[sudo] npm install -g id-uglifier
id-uglifier [options] input-file-globs
input-file-globs is a list of glob patterns https://www.npmjs.com/package/glob
or if starts with @ it will be read from a file with same rules as -idfile
id-uglifier has a safety mechanism to never overwrite the input
Where the options are:
-in pattern input filename regex pattern -out pattern output filename pattern -e exclude-files this is a glob pattern [https://github.com/isaacs/minimatch] that excludes files from being processed. Use multiple times to exclude multiple patterns or start with @ to retrieve from a file -off disabled the processing -noopt doesn't optimizes output ids by frequency -m|-mapfile name of map to generate with a list in-ids=out-ids if the mapfile ends with .json it will output a json format -idfile input filename with the list of ids, separated by LF or CRLF to be uglified lines starting with # will be discarded -ins|-insuffix input id suffix. default is _UG. use '.' to deactivates the default input suffix -outp|-outprefix output id prefix. default is ug_ -v verbose -version version
id-uglifier -in in-folder -out out-folder -m test/outmap.txt test/in-folder/**
test/in-folder/**, processes the ids,
outputs the to
and writes the id map to
out-folder doesn’t exists, it creates it on the fly
id-uglifier -noopt -in in-folder -out out-folder -ins . -ous ug__ -idfile test/idlist.txt -m test/outmap.json -e '*.css' test/in-folder/**
Same as above but deactivates order id by frequency,
the out map is in .json format,
loads an idlist file to uglify,
the output prefix is ug__ instead of ug_,
excludes all the ‘.css’ files
and disactivates the default input prefix
id-uglifier -noopt -in '\\.(\\w+)$' -out '.out.$1' test/in-folder/**
Writes the output to the same folder but adds .out to the extension
output will be
