Miscellaneous utilities

Usage

drop_items(items, which)

select_items(items, which)

drop_whitespace(items)

trim_whitespace(items)

include_whitespace(items, which)

split_chars(item, split = "")

new_block(...)

new_env(name, ...)

Arguments

items	A LaTeX2 object or list of items, or a LaTeX2item which is a list.
which	A LaTeX2range object describing which items to operate on, or a vector of indices into items.
item	A non-list LaTeX2item.
split	Where to split the characters.
...	Items to be passed to latex2().
name	The desired environment name.

Value

drop_items() returns the list of items with specific items removed.

select_items() returns the list of subsetted items.

drop_whitespace() returns the items with whitespace (blanks, tabs, newlines) removed.

trim_whitespace() returns the items with leading and trailing whitespace (blanks, tabs, newlines) removed.

include_whitespace() returns which with following whitespace (blanks, tabs, newlines) included.

split_chars() returns a LaTeX2 list containing the result of calling strsplit on the text of the item.

new_block() returns a BLOCK item containing the items.

new_env() returns an environment item containing the other items.

Note

drop_whitespace() will drop the whitespace that separates text items, so deparsing will merge them into a single item.

See Also

drop_whitespace() does not act recursively; use reduce_whitespace for that.

Examples

parsed <- parseLatex("Hello")
unclass(parsed)
unclass(split_chars(parsed[[1]]))
new_block(parseLatex("abc"))
new_env("itemize", parseLatex("\\item An item"))
