In this article, we'll first describe user settings as these are your personal settings for customizing VS Code. Later we'll cover Workspace settings, which will be specific to the project you're working on.
When you open the Settings editor, you can search and discover the settings you are looking for. When you search using the search bar, it not only shows and highlights the settings matching your criteria, but also filter out those which are not matching. This makes finding settings quick and easy.
As an example, let's hide the Activity Bar from VS Code. You might want to hide the Activity Bar to give the editor a little more room, or if you prefer to open views via the View menu or Command Palette.
You can now check and uncheck the Workbench > Activity Bar: Visible setting to hide and unhide the Activity Bar. Notice that when you have changed the setting value to be different than the default value, you see a blue line to the left.
The Settings editor search bar has several filters to make it easier to manage your settings. To the right of the search bar is a filter button with a funnel icon that provides options to easily add a filter to the search bar.
To check which settings you have configured, there is a @modified filter in the search bar. A setting shows up under this filter if its value differs from the default value, or if its value is explicitly set in the respective settings JSON file.
While you can reset settings individually via the Settings editor Reset Setting command, you can reset all changed settings by opening settings.json and deleting the entries between the braces . Be careful since there is no way to recover your previous setting values.
Note: A VS Code "workspace" is usually just your project root folder. Workspace settings as well as debugging and task configurations are stored at the root in a .vscode folder. You can also have more than one root folder in a VS Code workspace through a feature called Multi-root workspaces. You can learn more in the What is a VS Code "workspace"? article.
All features of the Settings editor such as settings groups, search, and filtering behave the same for Workspace settings. Not all User settings are available as Workspace settings. For example, application-wide settings related to updates and security can not be overridden by Workspace settings.
One way to customize language-specific settings is by opening the Settings editor, pressing on the filter button, and selecting the language option to add a language filter. Alternatively, one can directly type a language filter of the form @lang:languageId into the search widget. The settings that show up will be configurable for that specific language, and will show the setting value specific to that language, if applicable.
When you modify a setting while there is a language filter in place, the setting is configured in the given scope for that language.For example, when modifying the user-scope diffEditor.codeLens setting while there is a @lang:css filter in the search widget, the Settings editor saves the new value to the CSS-specific section of the user settings file.
If you have a file open and you want to customize the editor for this file type, select the Language Mode in the Status Bar to the bottom-right of the VS Code window. This opens the Language Mode picker with an option Configure 'language_name' language based settings. Selecting this opens your user settings.json with the language entry where you can add applicable settings.
Language-specific editor settings always override non-language-specific editor settings, even if the non-language-specific settinghas a narrower scope. For example, language-specific user settings override non-language-specific workspace settings.
You can scope language-specific settings to the workspace by placing them in the workspace settings just like other settings. If you have settings defined for the same language in both user and workspace scopes, then they are merged by giving precedence to the ones defined in the workspace.
You can use IntelliSense in settings.json to help you find language-specific settings. All editor settings and some non-editor settings are supported. Some languages have default language-specific settings already set, which you can review in defaultSettings.json by running the Preferences: Open Default Settings command.
You can configure language specific editor settings for multiple languages at once. The following example shows how you can customize settings for javascript and typescript languages together in your settings.json file:
Values with primitive types and Array types are overridden, meaning a configured value in a scope that takes precedence over another scope is used instead of the value in the other scope. But, values with Object types are merged.
If there are conflicting values, such as editor.selectionBackground in the example above, the usual override behavior occurs, with workspace values taking precedence over user values, and language-specific values taking precedence over non-language-specific values.
If you are using multiple language-specific settings, be aware that language-specific settings are merged and precedence is set based on the full language string (for example "[typescript][javascript]") and not the individual language IDs (typescript and javascript). This means that for example, a "[typescript][javascript]" workspace setting will not override a "[javascript]" user setting.
Some settings allow you to specify an executable that VS Code will run to perform certain operations. For example, you can choose which shell the Integrated Terminal should use. For enhanced security, such settings can only be defined in user settings and not at workspace scope.
You can share your user settings across your VS Code instances with the Settings Sync feature. This feature lets you share settings, keyboard shortcuts, and installed extensions across your VS Code installs on various machines. You can enable Settings Sync via the Backup and Sync Settings command on the right of the Settings editor or on the Accounts Activity Bar context menu.
In general, VS Code extensions store their settings in your user or workspaces settings files and they are available through the Settings editor UI (Preferences: Open Settings (UI) command) or via IntelliSense in your settings.json file (Preferences: Open User Settings (JSON) command). Searching by the extension name (for example gitlens or python) can help filter down settings to just those contributed by an extension.
Given that, for example, dictionaries, can be out of sync across nodes, mutations that pull values from them are disallowed on replicated tables by default. Enabling this setting allows this behavior, making it the user's responsibility to ensure that the data used is in sync across all nodes.
If true constant nondeterministic functions (e.g. function now()) are executed on initiator and replaced to literals in UPDATE and DELETE queries. It helps to keep data in sync on replicas while executing mutations with constant nondeterministic functions. Default value: false.
Although SET distributed_product_mode=global can change the queries behavior for the distributed tables, it's not suitable for local tables or tables from external resources. Here is when the prefer_global_in_and_join setting comes into play.
Another use case of prefer_global_in_and_join is accessing tables created by external engines. This setting helps to reduce the number of calls to external sources while joining such tables: only one call per query.
If force_index_by_date=1, ClickHouse checks whether the query has a date key condition that can be used for restricting data ranges. If there is no suitable condition, it throws an exception. However, it does not check whether the condition reduces the amount of data to read. For example, the condition Date != ' 2000-01-01 ' is acceptable even when it matches all the data in the table (i.e., running the query requires a full scan). For more information about ranges of data in MergeTree tables, see MergeTree.
If force_primary_key=1, ClickHouse checks to see if the query has a primary key condition that can be used for restricting data ranges. If there is no suitable condition, it throws an exception. However, it does not check whether the condition reduces the amount of data to read. For more information about data ranges in MergeTree tables, see MergeTree.
The http_make_head_request setting allows the execution of a HEAD request while reading data from HTTP to retrieve information about the file to be read, such as its size. Since it's enabled by default, it may be desirable to disable this setting in cases where the server does not support HEAD requests.
Enables or disables the insertion of default values instead of NULL into columns with not nullable data type.If column type is not nullable and this setting is disabled, then inserting NULL causes an exception. If column type is nullable, then NULL values are inserted as is, regardless of this setting.
When using the partial_merge algorithm, ClickHouse sorts the data and dumps it to the disk. The partial_merge algorithm in ClickHouse differs slightly from the classic realization. First, ClickHouse sorts the right table by joining keys in blocks and creates a min-max index for sorted blocks. Then it sorts parts of the left table by the join key and joins them over the right table. The min-max index is also used to skip unneeded right table blocks.
The direct algorithm performs a lookup in the right table using rows from the left table as keys. It's supported only by special storage such as Dictionary or EmbeddedRocksDB and only the LEFT and INNER JOINs.
Changes the way the GROUP BY clause treats the types of aggregation keys.When the ROLLUP, CUBE, or GROUPING SETS specifiers are used, some aggregation keys may not be used to produce some result rows.Columns for these keys are filled with either default value or NULL in corresponding rows depending on this setting.
