secretlint should respect megalinter ignored files/folders instead of .gitignore

[schorlton]

Opening this up as a separate issue from #1207 (comment) to keep it on your radar as it really does slow down the megalinter experience dramatically. Thanks again!!!

@schorlton now that .gitignore is automatically sent to secretlint when there is a gitignore + no secretlintignore, what do you think is remaining to do ? ^^

[schorlton]

Hi @nvuillam , thanks for circling back. Ideally secretlint would respect the ignored files in .mega-linter.yml instead of requiring its own secretlintignore? If secretlint needs a file listing files to ignore, perhaps something like writing megalinter's ignored files to a temp file and passing that to secretlint?

[nvuillam]

It would work if we had a .megalinterignore with same format than .gitignore ... maybe someday :) ( I agree that FILTER_REGEX_EXCLUDE is not so nice to use... )

[schorlton]

No worries! I seems like megalinter has a list of files internally that it is ignoring after it parses FILTER_REGEX_EXCLUDE...why not write that list to a tempfile and specify that tempfile to secretlint (or put it in in secretlintignore) if possible?

[nvuillam]

MegaLinter keeps the "not filtered" list of files, but not the filtered ones... maybe it could indeed be possible, but to be honest, it will probably wait for v6 except if a good soul decides to make a PR before ^^
