codespell - detect spelling mistakes in source code


codespell [OPTIONS] [file1 file2 ... fileN]


codespell is designed to find and fix common misspellings in text files. It is designed primarily for checking misspelled words in source code, but it can be used with other files as well.

usage: codespell [-h] [--version] [-d] [-c] [-w] [-D DICTIONARY]

[--builtin BUILTIN-LIST] [--ignore-regex IGNORE_REGEX] [-I FILE] [-L WORDS] [--uri-ignore-words-list WORDS] [-r REGEX] [--uri-regex URI_REGEX] [-s] [--count] [-S SKIP] [-x FILE] [-i INTERACTIVE] [-q QUIET_LEVEL] [-e] [-f] [-H] [-A LINES] [-B LINES] [-C LINES] [--config CONFIG] [files ...]

positional arguments:

files or directories to check

optional arguments:

-h, --help
show this help message and exit
show program's version number and exit
-d, --disable-colors
disable colors, even when printing to terminal (always set for Windows)
-c, --enable-colors
enable colors, even when not printing to terminal
-w, --write-changes
write changes in place if possible
custom dictionary file that contains spelling corrections. If this flag is not specified or equals "-" then the default dictionary is used. This option can be specified multiple times.
--builtin BUILTIN-LIST
comma-separated list of builtin dictionaries to include (when "-D -" or no "-D" is passed). Current options are: - 'clear' for unambiguous errors - 'rare' for rare but valid words - 'informal' for making informal words more formal - 'usage' for replacing phrasing with recommended
- 'code' for words common to code and/or mathematics
that might be typos
- 'names' for valid proper names that might be typos - 'en-GB_to_en-US' for corrections from en-GB to en-US The default is 'clear,rare'.
--ignore-regex IGNORE_REGEX
regular expression which is used to find patterns to ignore by treating as whitespace. When writing regular expressions, consider ensuring there are boundary nonword chars, e.g., "\bmatch\b". Defaults to empty/disabled.
-I FILE, --ignore-words FILE
file that contains words which will be ignored by codespell. File must contain 1 word per line. Words are case sensitive based on how they are written in the dictionary file
-L WORDS, --ignore-words-list WORDS
comma separated list of words to be ignored by codespell. Words are case sensitive based on how they are written in the dictionary file
--uri-ignore-words-list WORDS
comma separated list of words to be ignored by codespell in URIs and emails only. Words are case sensitive based on how they are written in the dictionary file. If set to "*", all misspelling in URIs and emails will be ignored.
-r REGEX, --regex REGEX
regular expression which is used to find words. By default any alphanumeric character, the underscore, the hyphen, and the apostrophe is used to build words. This option cannot be specified together with --writechanges.
--uri-regex URI_REGEX
regular expression which is used to find URIs and emails. A default expression is provided.
-s, --summary
print summary of fixes
print the number of errors as the last line of stderr
-S SKIP, --skip SKIP
comma-separated list of files to skip. It accepts globs as well. E.g.: if you want codespell to skip .eps and .txt files, you'd give "*.eps,*.txt" to this option.
-x FILE, --exclude-file FILE
FILE with lines that should not be checked for errors or changed
set interactive mode when writing changes: - 0: no interactivity. - 1: ask for confirmation. - 2: ask user to choose one fix when more than one is
- 3: both 1 and 2
-q QUIET_LEVEL, --quiet-level QUIET_LEVEL
bitmask that allows suppressing messages: - 0: print all messages. - 1: disable warnings about wrong encoding. - 2: disable warnings about binary files. - 4: omit warnings about automatic fixes that were
disabled in the dictionary.
- 8: don't print anything for non-automatic fixes. - 16: don't print the list of fixed files. As usual with bitmasks, these levels can be combined; e.g. use 3 for levels 1+2, 7 for 1+2+4, 23 for 1+2+4+16, etc. The default mask is 2.
-e, --hard-encoding-detection
use chardet to detect the encoding of each file. This can slow down codespell, but is more reliable in detecting encodings other than utf-8, iso8859-1, and ascii.
-f, --check-filenames
check file names as well
-H, --check-hidden
check hidden files and directories (those starting with ".") as well.
-A LINES, --after-context LINES
print LINES of trailing context
-B LINES, --before-context LINES
print LINES of leading context
-C LINES, --context LINES
print LINES of surrounding context
--config CONFIG
path to config file.
