typos-wIf there is any ambiguity (multiple possible corrections),typoswill just report it to the user and move on.False-positivesSometimes, what looks like a typo is intentional, like with people's names, acronyms, or localized content.To mark a word or an identifier (grouping of words) as valid, add it your_typos.tomlby declaring itself as the valid spelling:[default]extend-ignore-identifiers-re=[# *sigh* this just isn't worth the cost of fixing"AttributeID.*Supress.*",][default.extend-identifiers]# *sigh* this just isn't worth the cost of fixingAttributeIDSupressMenu="AttributeIDSupressMenu"[default.extend-words]# Don't correct the surname "Teh"teh="teh"For cases like localized content, you can disable spell checking of file contents while still checking the file name:[type.po]extend-glob=["*.po"]check-file=false(runtypos --type-listto see configured file types)If you need some more flexibility, you can completely exclude some files from consideration:[files]extend-exclude=["localized/*.po"]IntegrationsGitHub Actionspre-commit🐊Putout ProcessorVisual Studio Codetypos-lsp (Language Server Protocol server)Customtyposprovides several building blocks for custom native integrations-reads fromstdin,--write-changeswill be written tostdout--diffto provide a diff--format jsonto get jsonlines with exit code 0 on no errors, code 2 on typos, anything else is an error.Examples:# Read file from stdin, write corrected version to stdouttypos---write-changes# Creates a diff of what would changetyposdir/file--diff# Fully programmatic controltyposdir/file--formatjsonDebuggingYou can see what the effective config looks like by runningtypos--dump-config-You can then see how typos is processing your project withtypos--files

The[files]table controls how we walk files.
If you are usingfiles.extend-exclude,
are you running into#593?
If you are usingfiles.ignore-vcs = true,
is the file in your.gitignorebut git tracks it anyways?
Prefer allowing the file explicitly (see#909).Does the identifier show up intypos --identifersor the word show up intypos --words?If not, it might be subject to one of typos' heuristics for
detecting non-words (like hashes) or
unambiguous words (like words after a\escape).If it is showing up, likelytyposdoesn't know about it yet.typosmaintains a list of known typo corrections to keep the false positive
count low so it can safely run unassisted.This is in contrast to most spell checking UIs people use where there is a
known list of valid words.  In this case, the spell checker tries to guess your
intent by finding the closest-looking word.  It then has a gauge for when a
word isn't close enough and assumes you know best.  The user has the
opportunity to verify these corrections and explicitly allow or reject them.For more on the trade offs of these approaches, seeDesign.To correct it locally, see also ourFalse Positives documentation.To contribute your correction, seeContribute
