[cl-who-devel] CL-WHO:STR behavior and package nicknames.
(cl-who 0.6.0, linux, sbcl 0.9.13) Hi! In the documentation I find the following example: (:table :border (+ 1 2)) => (write-string "<table border='" s) (princ (+ 1 2) s) (write-string "' />" s) However, in my implementation I see the following: CL-USER> (cl-who:with-html-output-to-string (*standard-output*) (:table :border (+ 1 2))) "<table border='(+ 1 2)' />" This makes sense because CONSTANTP returns T for that form in SBCL and NIL in CMUCL. In which case I think I'm supposed to use the STR operator: CL-USER> (cl-who:with-html-output-to-string (*standard-output*) (:table :border (cl-who:str (+ 1 2)))) "<table3 border='3' />" ESC does pretty much the same thing. So does FMT I guess except it doesn't print the border attribute since the format call returns nil, which I think makes sense. Is this the expected behavior? Is there another way of having (:table :border (+ 1 2)) do what I want (output <table border='3' />)? Separately, would you consider adding the nickname "who" (or whatever you like, just shorter than "cl-who") to the package? Thanks, Erik.

This makes sense because CONSTANTP returns T for that form in SBCL and NIL in CMUCL.
Right, I didn't think of that. What I actually /meant/ in this case was that this form should be evaluated and I think because it is CONSTANTP this is one of the few occasions where usage of EVAL is OK. Anyway, I've uploaded a new version which does exactly that.
In which case I think I'm supposed to use the STR operator:
No, STR, ESC, and FMT aren't really meaningful in attribute positions. They are supposed to occur in the body of a tag.
Separately, would you consider adding the nickname "who" (or whatever you like, just shorter than "cl-who") to the package?
Done in 0.6.1. Thanks for the report, Edi.
