<div dir="ltr"><br><div style>Hi All,</div><div style><br></div><div style> I'm not sure if I should put this on this mailing list or as an Issue on the new Github site (where I could claim "First!" : )</div>
<div style><br></div><div style>How many of you have seen this error at some point during your time using cl-pdf:</div><div style><br></div><div style> "Error: Font Helvetica not Found" </div><div style><br></div>
<div style>As you probably know, one of the things which can cause this is when cl-pdf is being loaded from a compiled fasl which is not in the location of the source codebase, and the source codebase is no longer available at the location where it was during compiling.</div>
<div style><br></div><div style>So my basic question is: does anyone have suggestions what to do about *cl-pdf-base-directory* and *cl-typesetting-base-directory* so that a fasl or built runtime can be used without the depending on the original absolute pathname to afm/ directory, etc. still existing as they were during compilation? As it is currently, the full hardcoded pathname of the *cl-pdf-base-directory* and *cl-typesetting-base-directory* are baked into a compiled fasl. I understand this used to work from *load-truename* instead of *compile-file-truename*, and the hardcoding of compile-time source location was introduced as a "fix" for the fact that ASDF started using output-translations which resulted in the fasl being loaded not being in the source location. But this "fix" still assumes that the sources are always going to be available in their original location every time a fasl is loaded, which I consider to be a fragile assumption. <br>
</div><div style><br></div><div style>For me, the ideal solution would be: </div><div style><br></div><div style> 1. First of all, don't have any compile-time or load-time dependencies on these variables at all. As it is now, only chart.lisp in cl-pdf appears to depend on *afm-files-directories* -- couldn't this stuff be deferred to runtime? For cl-typesetting I'm not sure what are the dependencies at compile and load time, but I speculate that they are few. </div>
<div style><br></div><div style> 2. Provide an "initialize!" function for use at runtime startup, which is supposed to establish base directory locations for afm/ directory etc. </div><div style><br></div><div style>
<br></div><div style>Then it would be (as it rightfully should be) the responsibility of any runtime application which is using cl-pdf to set the *-base-directory* variables and call the initialize! function as part of its "restart" function, much the same way as many applications normally have to initialize themselves at startup to find the location of outside resources (e.g. webserver applications have to be set with the location of static files for publishing, etc). </div>
<div style><br></div><div style>Before I go any deeper into this direction I just wanted to get any feedback that current users have about this issue. And let me know if it should be opened as an Issue on the github project or stay on this mailing list. </div>
<div style><br></div><div style>Best Regards</div><div style><br></div><div style> Dave</div><div style><br></div><div style>P.S. Are there plans to bring cl-typesetting to github as well, side-by-side with cl-pdf? </div>
