semtab README
semtab is inspired by the tab behavior of HTML forms, allowing a user to
quickly jump between distinct meaningful input controls.
semtab provides keybindings that help developers quickly jump between entire
tokens in whatever programming language they're using, especially in cases
where a naive approach might result in multiple landing points within a token
or where multiple tokens are assigned a single landing point.
Features
Semtab provides two commands:
semtab.previousToken: Mapped to alt-j by defaultsemtab.nextToken: Mapped to alt-k by default
Both commands will jump your cursor to an adjacent token, and in most cases
highlight that token so you can immediately start typing to replace it. Semtab
includes a default list of tokens that it jumps to but doesn't highlight, such
as at the end of parameter lists, so that you can start typing to extend them.
When reaching the end or the beginning of the document, focus will wrap around.
Requirements
Semtab only works with languages that have syntax highlighting provided by a
TextMate grammar in VS Code.
Extension Settings
Semtab provides default values for the following settings:
semTab.relevantScopes: An array of TextMate scopes that your cursor will
land on and highlight in addition to the default scopessemTab.excludeScopes: An array of TextMate scopes that are not considered
useful for your cursor to land on, including things like assignment operators,
in addition to the default exclusionssemTab.zeroWidthLandings: An array of TextMate scopes that are useful to land
on, but which should not be highlighted, in addition to the default landings.
This includes scopes like the end of a function call, so you can extend th
parameter list, but where the closing symbol wouldn't be useful to highlight.
Known Issues
The default list of relevant scopes should have cross-language applicability, but
has been tested primarily for JSON, Typescript, and Python.
Performance could be better when using semtab to move through a large portion of a
file. It works fine for localized moves.
