Find a code sequence
Description
Find a code sequence
Usage
find_sequence(items, sequence, all = FALSE, ignore_whitespace = TRUE)
items_are_equal(items1, items2)
Arguments
items , sequence |
LaTeX2 objects or lists. |
all |
Whether to return all matches, or just the first. |
ignore_whitespace |
Whether to ignore whitespace in comparisons. |
items1 , items2 |
Two LaTeX2 or LaTeX2item objects. |
Details
find_sequence()
will only match sequences that
are entirely contained within a single list in items
.
Thus if prepare_table()
is called on a table, then
find_sequence()
will find sequences in the code before
or after the rows, or entirely within a single cell,
but not crossing alignment markers ("&"
).
Value
find_sequence()
returns a LaTeX2range or list of them where sequence
occurs within items
.
items_are_equal
returns a logical indicator of equality after removing source references.
Examples
find_sequence(parseLatex("a & b & c"), "b & c")
