With the prevalence of [[Unicode]], many systems render APL legibly out-of-the-box. However, for a uniform appearance, the font should be designed with APL in mind.<ref>Phil Chastney: ''[http://www.chastney.com/~philip/SImPL/APL_fonts_are_different.pdf APL fonts are different]'' | With the prevalence of [[Unicode]], many systems render APL legibly out-of-the-box.

== Changing font in Dyalog RIDE == | |||
[[Dyalog Ltd]]'s cross-platform RIDE interface, which is the default GUI interface on all non-Windows platforms, does not expose a font setting. However, it is trivial to change font: | |||
* Open ride-base.css[[#loc|*]] | |||
* Find the line that says <syntaxhighlight lang=css inline>src: url('./fonts/Apl385.woff') format('woff'), url('./fonts/Apl385.ttf') format('truetype');</syntaxhighlight> | |||
* Insert <syntaxhighlight lang=css inline>local('font name'),</syntaxhighlight> immediately after <syntaxhighlight lang=css inline>src:</syntaxhighlight>, for example <syntaxhighlight lang=css inline>src: local('SAX2'), url('./fonts/Apl385.woff') format('woff'), url('./fonts/Apl385.ttf') format('truetype');</syntaxhighlight> | |||
* Restart RIDE | |||
<span id=loc>[[#Changing font in Dyalog RIDE|*]]</span> The full path to ride-base.css varies (examples for RIDE 4.4 and Dyalog 18.2): | |||
:* Stand-alone installation: | |||
:** Windows: %LOCALAPPDATA%\Programs\Dyalog\Ride-4.4\resources\app\style\ride-base.css | |||
:** Linux: /opt/ride-4.4/resources/app/style/ride-base.css | |||
:** macOS: /Applications/Ride-4.4.app/resources/app/style/ride-base.css | |||
:* Zero-footprint RIDE (served by the interpreter and normally accessed through a browser): | |||
:** Linux or AIX: /opt/mdyalog/18.2/64/unicode/Contents/Resources/Dyalog/RIDEapp/resources/app/style/ride-base.css | |||
:** macOS: /Applications/Dyalog-18.2.app/Contents/Resources/Dyalog/RIDEapp/resources/app/style/ride-base.css | |||
