Features

Installation

Search for Spell Right from the extension installer within VSCode or execute below line in the command palette (F1 or Ctrl+Shift+P):

ext install ban.spellright

Spell Right requires spelling back-end which is different for various platforms. Please read carefully the section below on how to provide dictionaries for Spell Right to work properly.

If you have any problem with installation or you see that Spell Right does not work with some type of document please read carefully the lengthy README file below and if nothing seems to be related to the problems you face post an issue here.

Dictionaries

Windows 8+

On Microsoft Windows from version 8 on Spell Right uses system spelling API. Follow system guidelines, like here or here, on how to install additional system spelling dictionaries.

macOS

On macOS Spell Right uses system spelling API.

Linux and Windows 7

On Linux/ and Windows 7 Spell Right uses built in Hunspell spell checker library. To use it a pair of Dictionary (*.dic) and Affixes (*.aff) files with UTF-8 encoding have to be downloaded (remember to download RAW files) e.g. from here (multiple languages), here (Portuguese) or here (French) and placed in Dictionaries subfolder of VSCode's user global configuration directory, located at:

Dictionaries subfolder does not exists there by default and has to be created manually.

In case you run Insiders edition of VSCode then Code part of the path has to be changed to Code - Insiders appropriately.

Spell Right cannot automatically match the dictionary name with system locale settings when using Hunspell dictionaries hence at first run dictionary has to be selected manually (e.g from status bar).

On most Linux distributions system-wide dictionaries can be reused (for now only UTF-8 encoded dictionaries are supported, verify SET line in *.aff file) by soft linking the system folder e.g.:

ln -s /usr/share/hunspell/* ~/.config/Code/Dictionaries

The location may vary among distributions (e.g.: on Fedora Linux it is /usr/share/myspell etc.) It also has been suggested that some flavors of Linux require that the dictionary name should not contain spaces and/or parentheses.

Dictionaries from the folder will be listed in the language selection list and used for spelling documents. Because Hunspell engine is slower in serving suggestions to misspelled words it may be useful to set spellright.suggestionsInHints to false which will speed spelling up and suggestions will still be available in context menu called upon action for the suggestion.

WSL/Remote/GitHub Repositories

While editing WSL/Remote/GitHub files (Remote SSH/Remote-WSL) SpellRight should use host dictionaries so all the above should apply.

User Dictionaries

Spell Right stores words considered as spelled correctly and not existing in the main spelling engine (a.k.a. ignored words) in plaintext dictionary files. All the extension's commands add words to two main files, user and workspace dictionaries, both contained in spellright.dict files, one located in user settings folder and the other in workspace settings folder (.vscode). Besides these there can be any number of *.dict files in workspace settings folder e.g. dictionaries containing specialized vocabularies like medical terms, trademark names etc. User dictionary is always used and workspace dictionaries are used in the context of opened folder. All provided dictionaries are used in conjunction.

Symbols in Source Code Documents

When spelling source code class of document which provides symbol information for the document (e.g. the symbols which are used when Ctrl+Shift+O is pressed to perform GoTo symbol operation) the symbols are used for spelling of the document. It reduces the number of false spelling warnings mostly in comments which provide source code documentation on the usage of these symbols, e.g. variables, function parameters etc.

Use F8 or Shift+F8 to jump to next/previous spelling error.

Changing Language and Turning OFF

Extension has a handy list interface for switching spelling dictionary (language) or turning spelling OFF for currently open document type:

dictionary

It can be reached by clicking on indicator field with an "eye" symbol in status bar:

switch

Alternatively same result can be achieved selecting command SpellRight: Select Dictionary (Language) or SpellRight: Turn OFF for Current Document Type from the command palette (F1/Ctrl+Shift+P).

Status bar indicator also shows when spelling for particular document class has been turned OFF:

switch

Or when it has been forced OFF by In-Document command (spellcheck-off) or rule in .spellignore:

switch

Multiple languages in one document

Language selector allows to select more than one language. Document is then spelled using all of the dictionaries and when a token (word) is considered correct in one of the dictionaries it is considered as spelled correctly. When it is not, then suggestions for all selected languages are shown.

Language can also be switched by using In-Document command spellcheck-language placed within document:

switch

And when at least one language spelled is missing dictionary:

switch

Commands

This extension contributes the following commands:

SpellRight: Select Dictionary (Language)

Pops dictionary selection list. Selecting language also turns spelling ON. The list also allows to turn spelling OFF for currently open document type. Can also be reached by clicking indicator field in status bar.

SpellRight: Turn OFF for Current Document Type

Turn spelling OFF for currently open document type.

SpellRight: Open User Dictionary File

Open in editor spellright.dict file from user settings folder.

SpellRight: Open Workspace Dictionary File

Open in editor spellright.dict file from workspace settings folder (.vscode) appropriate for currently open document in (multi root) workspace.

SpellRight: Add Selection to Workspace Dictionary

Add text selected in editor to main workspace dictionary appropriate for currently open document in (multi root) workspace.

SpellRight: Add Selection to User Dictionary

Add text selected in editor to main user dictionary.

SpellRight: Update Configuration

Saves current state of GUI (that is language and map of documents classes spell checked) to appropriate configuration file. Works only if "spellright.configurationUpdate" is set to false.

Settings

This extension contributes the following settings (with default values):

"spellright.language": [ "" ]

Default language (dictionary/country name) used for spelling. Typically in a LANGUAGE (e.g.: "en", "fr", when "spellright.groupDictionaries" is true) or LANGUAGE-COUNTRY format (e.g.: "en-US", "en-GB", "fr-CA", "pl-PL", when "spellright.groupDictionaries" is false). When Hunspell spelling engine is used (e.g. in Windows 7) this setting should be the name of the dictionary file without extension. In case language parameter is not set then language from OS locales is used.

"spellright.statusBarIndicator": true

Enable/disable language & status indicator switch in status bar.

"spellright.suggestionsInHints": true

Enable/disable including suggested corrections in hints. Disabling suggestions significantly speeds checking up. May be useful in case of large, often switched or saved documents.

"spellright.addToSystemDictionary": false

When true words added to user dictionary are stored in system default custom spelling dictionary instead.

"spellright.groupDictionaries": true

Enable/disable grouping of dictionaries by language. Disabling grouping results in displaying dictionaries for all regional variants (e.g. en-US, en-GB, en-CA etc.) as separate entries. When enabled regional dictionaries are displayed as single dictionary under common language name (e.g. "English"). Works only on native Windows & macOS spelling APIs.

"spellright.recheckOnSave": false

Enable/disable re-checking of entire document after file is saved.

"spellright.documentTypes": [ "plaintext", "markdown", "latex" ]

Document types for which spelling will be turned ON by default.

"spellright.ignoreRegExps": []

Regular expressions ignored in spelling. Allows to ignore/consider as spelled correctly generalized expressions. Works on raw document before separating words to spell which allows to ignore larger parts of the document. Regular expressions have to be in double quoted JavaScript regular expression format. That is backslash has to be quoted as well e.g.: "/(\\.?)(gif|png)/g" to ignore file extensions like ".gif" and ".png".

"spellright.ignoreRegExpsByClass": {}

Extends setting of "spellright.ignoreRegExps" per document type. Accepts object of key-multi-value pairs. For example following settings:

"spellright.ignoreRegExpsByClass": {
    "markdown": [ "/&/g", "/ /g" ],
    "cpp": [ "/#include\\s+\\\".+\\\"/g" ],
    "html": [ "/<script>[^]*?</script>/gm" ],
    "latex": [ "/\\\\begin{minted}[^]*?\\\\end{minted}/gm" ]
}

Please mind the fact that both "spellright.ignoreRegExps" and "spellright.ignoreRegExpsByClass" may have serious impact on performance. They are applied on whole document before every, even smallest spell check, has to reapply these filters so they may cost time in complicated expressions.

"spellright.ignoreFiles": [ "**/.gitignore", "**/.spellignore" ]

Set of file patterns to globally, silently exclude files from being spelled. Files described with this setting will not be reported as forced OFF spelling (red indicator in status bar). Patterns defined as for gitignore.

"spellright.notificationClass": "error"

Allows to change class of diagnostic messages produced by Spell Right which changes in turn underline color. Possible values (with corresponding underline color) are: "error" (red), "warning" (green), "information" (green), "hint" (invisible).

"spellright.notificationClassByParser": {}

Extends "spellright.notificationClass" to allow change class of diagnostic messages per parser. For example following settings:

"spellright.notificationClassByParser": {
    "code": "information"
}

will produce "information" class diagnostics for documents spelled with code parser. Possible values on left side of the association are: plain, markdown, code, latex and xml.

"spellright.spellContext": "body comments strings"

Allows to enable (present in string) or disable (absent in string) spelling of syntactic parts of the documents. Currently supported are:

"spellright.spellContextByClass": {}

Same as "spellright.spellContext" but per document type. Accepts object of key-value pairs. For example following settings:

"spellright.spellContextByClass": {
    "latex": "body",
    "cpp": "comments",
    "python": "strings"
}

"spellright.languageContext": {}

Allows to decide on which language is used to spell syntactical parts of the documents. For example following settings:

"spellright.languageContext": {
    "strings": [ "en-US" ],
    "comments": [ "en-GB" ]
}

will spell strings in American English and comments in British English of course if the "spellright.groupDictionaries" flag is set to false.

Configuration item "spellright.languageContext" is more important than "spellright.language" but less important than In-Document commands.

"spellright.languageContextByClass": {}

Same as "spellright.languageContext" but per document type. For example following settings:

"spellright.languageContextByClass": {
    "latex": {
        "body": [ "fr" ],
        "comments": [ "en" ]
    }
}

will spell body of latex documents in French and comments in English.

Configuration item "spellright.languageContextByClass" is more important than "spellright.language" and "spellright.languageContext" but less important than In-Document commands.

"spellright.configurationUpdate": true

If set to true then each operation on the GUI (change of language, turning spelling OFF for particular document type) is automatically saved in appropriate configuration settings (workspace if workspace is open and user if not). Setting to false requires using of "spellright.configurationUpdate" command to save the changes performed in GUI.

"spellright.configurationScope": "workspace"

Allows to decide which configuration gets updated when "spellright.configurationUpdate" is set to true. Possible values are user and workspace.

"spellright.latexSpellParameters": (see below for default value)

Defines LaTeX commands that should have both mandatory ([]) and optional ({}) parameters spelled. Other commands are removed from spelling. Default value:

"spellright.latexSpellParameters": [
    "author",
    "title",
    "date",
    "chapter",
    "section\\*?",
    "subsection\\*?",
    "subsubsection\\*?",
    "part",
    "paragraph",
    "subparagraph",
    "text(rm|sf|tt|md|bf|up|it|sl|sc|normal)",
    "underline",
    "emph",
    "item",
    "footnote(text)?",
    "caption(of)?",
    "multicolumn",
    "href",
    "hyperref",
    "begin\\{frame\\}"
]

"spellright.parserByClass": {}

Allows to assign or override generic parser for particular document class. For example following settings:

"spellright.parserByClass": {
    "perl": {
        "parser": "code"
    }
}

assigns parser of generic type code (Source Code Parser) to perl (Perl) document class. Possible values are:

"spellright.useDocumentSymbolsInCode": true

If set to true Spell Right will use document symbols (variable, function names etc.) when spelling source code documents. Significantly reduces number of misspelled words in doc-strings and in comments whenever a symbol used in code is used and the symbol does not disassemble to properly spelled parts using CamelCase, snake_case etc. separation.

In-Document Commands

Beside global settings following commands can be embedded inside spelled parts of the document (e.g.: comments, strings etc.):

spellcheck-language "CODE" ["CODE"]* (alternative syntax: spellcheck: language "CODE" ["CODE"]* and !TEX spellcheck = "CODE", but with only one language code in comment areas of latex document class only)

Forces switching spelling language for the following part of the document or until next spellcheck-language "CODE" command. CODE is language code according to used spellcheck background service, typically in a LANGUAGE or LANGUAGE-COUNTRY format (e.g.: "en", "fr", "en-US", "en-GB", "fr-CA", "pl-PL" etc.) If CODE is empty switches back to default spelling language.

In-Document commands for switching spelling language have highest priority over "spellright.languageContextByClass" and "spellright.languageContext" and "spellright.language" configuration items.

spellcheck&#x2d;off (alternative syntax: spellcheck: off)

Forces spelling OFF for the entire document despite global settings.

spellcheck&#x2d;on (alternative syntax: spellcheck: on)

Forces spelling ON for the entire document despite global settings. Has higher priority than turning spelling off with both In-Document spellcheck&#x2d;off command and .spellignore patterns.

Ignore file

.spellignore file located in workspace root directory, appropriate to currently open file in (multi root) workspace, can be used to disable spelling for files described by gitignore syntax file patterns.

Unknown document type

Spell Right must have an idea of the document structure in order to be able to spell it. Most document types have parts that do not need to be spelled (e.g. code blocks in Markdown, commands in LaTeX documents etc.) When an unregistered document type is encountered then Spell Right proposes a list of generic parsers to choose from:

dictionary

Select appropriate class to be able to spell the document. If spellright.configurationUpdate is set to true assignment will be written to the configuration settings either user or workspace according to the value of spellright.configurationScope setting.
