Coqide 8.5: No Syntax Highlighting on Linux

Coqide 8.5: No syntax highlighting on Linux

I have libgtksourceview3.0-common installed but CoqIDE depends on libgtksourceview2.0-common. Installing the latter fixed it

Coq: a single notation for multiple constructors

You can create a typeclass with the constructors as instances and let the instance resolution mechanism infer the constructor to call for you:

Class A_const (X:Type) : Type :=
  a_const : X -> A.
Instance A_const_c : A_const C := c.
Instance A_const_d : A_const D := d.

Check a_const c1.
Check a_const d2.

By the way, with Coq 8.5, if you really want a notation ' x to result in the exact constructor applied to x, rather than e.g. @a_const C A_const_c c1, then you can use ltac-terms to accomplish that:

Notation "' x" := ltac:(match constr:(a_const x) with
                        | @a_const _ ?f _ =>
                          let unfolded := (eval unfold f in f) in
                          exact (unfolded x)
                        end) (at level 0).
Check 'c1. (* c c1 : A *)
Check 'd2. (* d d2 : A *)

NodeJS Server pdf Document Generation Issue

Was able to solve this issue by adding a single CSS style Rule.

html {
zoom: 0.55;
}

This is most likely required due to the default zoom setting of the html-pdf package. This setting and more can also be configured with options; however, i am unsure if the zoom options can be configured to < 1.
