this is dictated through the <code class="inline-code">foldmethod</code> variable;
|
||
|
|
for more information for the following methods, see <code class="inline-code">fold-${VALUE}</code> with the <a href="/wiki/editor.neovim.help-system">Neovim help system</a></p><ul><li><p>with <code class="inline-code">manual</code> value, no additional actions are done
|
||
|
|
</p></li><li><p>with <code class="inline-code">marker</code> value, a fold will be created ala-HTML markers
|
||
|
|
</p></li><li><p>with <code class="inline-code">expr</code> value, a fold will be managed through its fold level evaluated from <code class="inline-code">foldexpr</code> function;
|
||
|
|
certain tools like <a href="https://github.com/nvim-treesitter/nvim-treesitter">nvim-treesitter</a> takes advantage of this to arrange the code through its blocks, scope, etc.
