Some utils related to Pass Tracking for Qml.
@author Mathieu Barbin
This module defines some utils for branching compilers working on QmlAst with
the pass tracking system developed in passlib, in [PassHandler] and [PassTracker]
In particular, it defines, given a [QmlAst.code] extractor some :
+ [printers]
+ [trackers]
Any language should implement a module named [LangTracker], [LangCheck], etc...
@see "passlib/" for a global overview of the Pass System
(** {6 Utils} *)
val contains_tracker : QmlAst.expr -> bool
(** {6 Printers} *)
(** Regroup some of common printer of the module [Printer] in one list .
The ignored argument is for an optimal branching with PassHandler.
+ code
+ declaration
+ size
TODO: some more flexibility in passhandler options so that we can export
in this list douzen of specific printers without risking that they will
all be printed with a --print-all.
val printers : ('env -> QmlAst.annotmap * (QmlTypes.gamma * QmlTypes.gamma) * QmlAst.code) -> 'opt -> (PassHandler.printer_id * 'env PassHandler.printer) list
module Printer :
Regular ast printer:
print the full code using the Pretty Printer of the language
and insering multiple new lines so that meld can better do
the correspondancy between values.
val code : QmlAst.code PassHandler.printer
Regular ast size printer:
print the size of the code using opatrack conventions.
Used by passtracker hudson.
val size : QmlAst.code PassHandler.printer
Outputs only the toplevel values without the bodies, like :
type toto
dbval ...
Usefull to have a global overview of the code, and tracking
inserted/removed toplevel values by a pass.
val declaration : QmlAst.code PassHandler.printer
Print only the code_elt which contains at least one tracked expression
val tracked : QmlAst.code PassHandler.printer
(** {6 Trackers} *)
(** Regroup all the trackers of the module [Tracker] in one list .
The ignored argument is for an optimal branching with PassHandler.*)
val trackers : ('env -> QmlAst.code) -> 'opt -> (PassHandler.tracker_id * 'env PassHandler.tracker) list
module Tracker :
A tracker for (`tracker Tracker.t) directives
val directive : QmlAst.code PassHandler.tracker
A tracker for top level definitions
val val_ : QmlAst.code PassHandler.tracker
