create a noop preset

[millermedeiros]

this preset wouldn't make any changes to the input, that way we can implement style changes that are less obtrusive and don't need to reset all the properties (just inherit from the noop preset and override the needed options).

this will only be possible after we add support for -1 to the config options.

PS: issue #1 and #84 are blocking this.

this is still not possible, there are still some calls to _tk.remove and _tk.removeEmpty[InBetween|AdjacentBefore|AdjacentAfter]... which means that passing the code through esformatter will always cause side effects.

lowering the priority for now since there are more important bugs to fix. but I would really like to have a noop preset in the future, since this proves that tool is really configurable. (even tho convention > configuration)

Would creating a default preset with options to set to -1 be a good start here?

It would be nice to have the option to use esformatter from a noop state, and configure it as needed. Hunting down how some of the different rules interact with each other can be tedious.

[millermedeiros]

that wouldn't help.. we are planning to kill all the presets besides the default (convert them into plugins). right now even if all settings are -1 it will still change the code.

[millermedeiros]

I'm not going to work on this.. if you don't want the code to change use a different tool, maybe echo or tee 😜

[bcomnes]

Thats fair given the work involved :)

for future reference:

we have a bunch of calls to limit that passes a number as second argument - these changes will always happen, no matter what settings you pass. Most of the cases are actually things that you want to happen (eg. always enforce a single space after the new keyword), but in some cases they are hardcoded just because we didn't have a name for that option or didn't think anyone would need to configure that...

There is also the indent.sanitize call (which will remove the original indentation) - we always re-indent the whole file, but this should be easy to ignore with a flag...
