Algo
A Typst library for writing algorithms. On Typst v0.6.0+ you can import the algo
package:
#import "@preview/algo:0.3.3": algo, i, d, comment, code
Otherwise, add the algo.typ
file to your project and import it as normal:
#import "algo.typ": algo, i, d, comment, code
Use the algo
function for writing pseudocode and the code
function for writing code blocks with line numbers. Check out the examples below for a quick overview. See the usage section to read about all the options each function has.
Examples
Here's a basic use of algo
:
#algo(
title: "Fib",
parameters: ("n",)
)[
if $n < 0$:#i\ // use #i to indent the following lines
return null#d\ // use #d to dedent the following lines
if $n = 0$ or $n = 1$:#i #comment[you can also]\
return $n$#d #comment[add comments!]\
return #smallcaps("Fib")$(n-1) +$ #smallcaps("Fib")$(n-2)$
]
Here's a use of algo
without a title, parameters, line numbers, or syntax highlighting:
#algo(
line-numbers: false,
strong-keywords: false
)[
if $n < 0$:#i\
return null#d\
if $n = 0$ or $n = 1$:#i\
return $n$#d\
\
let $x <- 0$\
let $y <- 1$\
for $i <- 2$ to $n-1$:#i #comment[so dynamic!]\
let $z <- x+y$\
$x <- y$\
$y <- z$#d\
\
return $x+y$
]
And here's algo
with more styling options:
#algo(
title: [ // note that title and parameters
#set text(size: 15pt) // can be content
#emph(smallcaps("Fib"))
],
parameters: ([#math.italic("n")],),
comment-prefix: [#sym.triangle.stroked.r ],
comment-styles: (fill: rgb(100%, 0%, 0%)),
indent-size: 15pt,
indent-guides: 1pt + gray,
row-gutter: 5pt,
column-gutter: 5pt,
inset: 5pt,
stroke: 2pt + black,
fill: none,
)[
if $n < 0$:#i\
return null#d\
if $n = 0$ or $n = 1$:#i\
return $n$#d\
\
let $x <- 0$\
let $y <- 1$\
for $i <- 2$ to $n-1$:#i #comment[so dynamic!]\
let $z <- x+y$\
$x <- y$\
$y <- z$#d\
\
return $x+y$
]
Here's a basic use of code
:
#code()[
```py
def fib(n):
if n < 0:
return None
if n == 0 or n == 1: # this comment is
return n # normal raw text
return fib(n-1) + fib(n-2)
```
]
And here's code
with some styling options:
#code(
indent-guides: 1pt + gray,
row-gutter: 5pt,
column-gutter: 5pt,
inset: 5pt,
stroke: 2pt + black,
fill: none,
)[
```py
def fib(n):
if n < 0:
return None
if n == 0 or n == 1: # this comment is
return n # normal raw text
return fib(n-1) + fib(n-2)
```
]

)
Parameters:
-
body
:content
— Main algorithm content. -
header
:content
— Algorithm header. If specified,title
andparameters
are ignored. -
title
:string
orcontent
— Algorithm title. Ignored ifheader
is specified. -
Parameters
:array
— List of algorithm parameters. Elements can bestring
orcontent
values.string
values will automatically be displayed in math mode. Ignored ifheader
is specified. -
line-numbers
:boolean
— Whether to display line numbers. -
strong-keywords
:boolean
— Whether to strongly emphasize keywords. -
keywords
:array
— List of terms to receive strong emphasis. Elements must bestring
values. Ignored ifstrong-keywords
isfalse
.The default list of keywords is stored in
_algo-default-keywords
. This list contains the following terms:("if", "else", "then", "while", "for", "repeat", "do", "until", ":", "end", "and", "or", "not", "in", "to", "down", "let", "return", "goto")
Note that for each of the above terms,
_algo-default-keywords
also contains the uppercase form of the term (e.g. "for" and "For"). -

i
and d
For use in an algo
body. #i
indents all following lines and #d
dedents all following lines.
comment
For use in an algo
body. Adds a comment to the line in which it's placed.
comment(
body,
inline: false
)
Parameters:
-
body
:content
— Comment content. -
inline
:boolean
— If true, the comment is displayed in place rather than on the right side.NOTE: inline comments will respect both
main-text-styles
andcomment-styles
, preferringcomment-styles
when the two conflict.NOTE: to make inline comments insensitive to
strong-keywords
, strong emphasis is disabled within them. This can be circumvented via thetext
function:#comment(inline: true)[#text(weight: 700)[...]]
no-emph
For use in an algo
body. Prevents the passed content from being strongly emphasized. If a word appears in your algorithm both as a keyword and as normal text, you may escape the non-keyword usages via this function.
no-emph(
body
)
Parameters:
-
body
:content
— Content to display without emphasis.

Makes a code block element.
