pascalh / astview Goto Github PK

Currently the AstState contains three fields for internal program state, gtk gui types and program options. The gtk types don't really belong here, since they are an implementation detail for the gtk-implementation.

Task: Remove the gtk types from this type and make them accessible via a Reader monad. This will most probably lead to a larger refactoring.

Please let me know if you need more info on the problem.

Since reparsing is manually binded to ctrl+p, the keyboard shortcut is not displayed in the respective menu item, although it should be shown there.

bnfc-meta provides an easy way of defining parsers. Unfortunately it doesn't provide support for source locations (yet). Hence, this task is only about proving an example parser on how to use bnfc with astview. Probably just use the javalette example language.

For now it might make sense to just ignore the syntax highlighting for the generated language (and maybe add it later on in a separate task).

To update the dependencies #17 (gtk doesn't seem to be supported much) and improve decoupling of program state and gtk #11, I decided to give a rewrite of astview using gi-gtk-declarative a try.

• Use stack to build on travis
• Make astview compile with ghc-8.*
• Remove the travis build with older versions of ghc

I am working on the Haskell Refactorer at https://github.com/alanz/HaRe, and would like to have a way to examine the AST (RenamedSource) and token stream, while working on it.

I made a basic attempt at https://github.com/alanz/HaRe/tree/ghc-api/hareview but got stuck on versions of glade/gtk etc.

Would this be possible without too much effort now that you seem to have come back to this again?

Test (for each supported language) whether

• the parser can parse source files
• source location extraction (from the parsed and transformed abstract syntax tree) works

As haskell-src-extswill be discontinued, astview needs to change to a different lib. ghc-lib-parser seems to be its replacement

Add support for other languages, which are shipped with lts-7-24

Ideas:

• graphviz dot files
• json

Master builds against lts-7.24 which is already a year old. Bump dependencies to build with a newer LTS version (opt for LTS 12.5)
