reading from a named pipe in Pharo

by Siemen Baader

Hi, I'd like to use an external tool to edit HTML code and then store and version it in my Pharo image. I'd like to create a named pipe that the external application will save to, and then have Pharo watch for whenever the named pipe is written to and then execute code to handle the data from there. But I can't find any place to register a callback on FileReference and similar classes that will notify Pharo when the named pipe is changed, and when the external editor will read from it. Is there any support for this? I know there are workarounds like polling or reading the file when it is used, but I'd prefer to wire things together directly and avoid duplicating the data if possible. thanks, Siemen

Richard Sargent wrote > a disambiguation page with a lengthy list IMHO this is irrelevant. My proposal included a method comment, which would provide the google-able term, as well as potentially a good enough summary that one wouldn't have to leave the image. The fact that the method belongs to CompiledMethod is the disambiguation. The internet is meaningless and flat compared to the context and structure of a ST image. Richard Sargent wrote > Do not use comments embedded *inside* methods to cover for naming the > method badlyâ¦ Also, if one Googles an acronym How is a harder-to-type thing that the user doesn't understand but is easier to google better than a comment that gives the necessary context right in the image? My ideal image would avoid the need to Google as much as possible, suggesting a comment either way, so nothing lost. There's nothing inherently "bad" about an acronym. For example, no one's been banging down the door to rename "JPEGReadWriter" to "JointPhotographicExpertsGroupReadWriter". In that case, it's because the acronym is so well-known, but what I'm asking whether #ast is a similar candidate for exception because it is so unknown (i.e. compiler domain-specific) that a user is likely to know either the term and the acronym or neither. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

But my stupid question is why it's still called abstract > while it is implemented for concrete language? This is to make the difference between the parse tree (or concrete syntax tree) and the transformation of that parse tree into an abstract syntax tree (where a bunch of syntax tree nodes created by the parsing are removed or made absent... they are not needed to represent the code structure). Hence the abstract: the abstract syntax tree is an abstraction of the parse tree, even if it represent an exhaustive view of a concrete piece of code. https://web.stanford.edu/class/archive/cs/cs143/cs143.1128/lectures/02/Slid…, slide 159 onward. > That, to me, is as opaque as > the acronym for one not acquainted with the domain, and may > buy us little at > the cost of a good amount of extra typing.
