APL logo: Difference between revisions

As of {{CURRENTMONTHNAME}} {{CURRENTYEAR}}, APL does not have a logo like many other programming languages do. After a consensus at their September 9th 2021 [[BAA webinar|webinar]], [[BAA]] will head an effort to adopt a universal [[vendor]]-agnostic logo for APL. This article collects draft proposals for the universal APL logo. Feel free to [{{fullurl:{{FULLPAGENAME}}|action=edit&section=1}} add your own].

To leave feedback on or ideas for the existing proposals, see the [[{{TALKPAGENAME}}|Discussion page]].

This is a cube, which is a common APL motif, e.g. used for [[APL2]] (including the book [[Books#APL2_at_a_Glance|APL2 at a glance]]), [[APL*PLUS]] and [[Dyalog APL]]. However, one quarter has been modified to resemble a leaf, thus making the cube into an [[apple]], another common association with APL. The leaf is supposed to hint at the [[Del]] which symbolises [[function]] definition and has been used in application icons for [[APL+]] and [[APLX]]. The green colours come from [[IBM]]'s modern '''Carbon''' design to honour IBM's role APL's history. The lettering spells out "APL" while also hinting at APL's usage of special [[glyphs]]; here <code>⍝⍴⌊</code> which look very close to the forms found in the widespread ''APL385 Unicode'' [[font]].

[[:File:I_like_APL_graphic.jpg|original "I like APL" apple motif]]; the green colour also recognises this original motif. As with some of the other suggestions, the simplicity and single colour means that it would still work well when shrunk to the size of a favicon and could be rendered in black and white without loss of detail.

The [[APL Wiki logo]] encapsulates features of APL, is visually striking and takes an interesting new approach over traditional apple or cube designs. Its use here has already established its independent, community-wide use. It works in a variety of sizes and its simple black and white palette makes it suitable for all media forms. It could be enhanced with the letters A P L either underneath, or within the middle dots of the middle row.
