* Some notes on the syntax of this file, making it possible to use todoo-mode.el:
|
|
|
|
- Items start with "* "
|
|
- Sub-items start with "- "
|
|
- It should be noted somewhere in the item, who has reported the item
|
|
Suggestion: Add "[who]" at the beginning of the item title
|
|
(then one can use "assign item" in todoo-mode)
|
|
- Each item should have a priority
|
|
Suggestion: Add "URGENT", "IMPORTANT" or "WISH" at the beginning of
|
|
the item title
|
|
- Sort the items in priority order
|
|
(todoo-mode can move an item up or down)
|

* [peb] URGENT: Error messages for syntax errors
|
|
|
|
When a syntax error is reported, it should be noted which file it
|
|
is. Otherwise it is impossible to know where the error is
|
|
(if one uses the -s flag):
|
|
|
|
> i -s Domain/MP3/Domain_MP_Semantics.gf
|
|
syntax error at line 33 before ve , Proposition ,
|
|
|
|
There's no problem with other kinds of errors:
|
|
|
|
> i -s Domain/MP3/Domain_MP_Semantics.gf
|
|
checking module Godis_Semantics
|
|
Happened in linearization of userMove :
|
|
product expected instead of {
|
|
pl : Str
|
|
}
|
|
|
|
|
|
* [peb] IMPORTANT: Add the -path of a module to daughter modules
|
|
|
|
Then the main module does not have to know where all grandchildren are:
|
|
|
|
file A.gf:
|
|
abstract A = B ** {...}
|
|
|
|
file B.gf:
|
|
--# -path=./resource
|
|
abstract B = Lang ** {...}
|
|
|
|
I.e.: the file A.gf should not need to know that B.gf uses the
|
|
resource library.
|
|
|
|
|
|
* [peb] IMPORTANT: incomplete concrete and interfaces
|
|
|
|
- The following works in GF:
|
|
|
|
incomplete concrete TestDI of TestA = open (C=TestCI) in {
|
|
lincat A = TestCI.A ** {p : Str};
|
|
lin f = TestCI.f ** {p = "f"};
|
|
g = TestCI.g ** {p = "g"};
|
|
}
|
|
|
|
> i -src TestDE.gf
|
|
|
|
- BUT, if we exchange "TestCI" for "C" we get an error:
|
|
|
|
incomplete concrete TestDI of TestA = open (C=TestCI) in {
|
|
lincat A = C.A ** {p : Str};
|
|
lin f = C.f ** {p = "f"};
|
|
g = C.g ** {p = "g"};
|
|
}
|
|
|
|
> i -src TestDE.gf
|
|

|
|
fun f, g : A;
|
|
}
|

|
|

|
|
oper hello = "hello";
|

}

|

|
|
}
|
|
|
|
concrete TestCE of TestA = TestCI with (TestBI = TestBE);
|
|
|
|
incomplete concrete TestCI of TestA = open TestBI in {
|
|
lincat A = {s : Str};
|
|

|
}

* [peb] IMPORTANT: Set GF_LIb-PATH within GF
|
|
|
|
> sf libpath=~/GF/lib
|
|
|
|
|
|
* [peb] IMPORTANT: Set the starting category with "sf"
|
|
|
|
> sf startcat=X
|
|
|
|
|
|
* [peb] IMPORTANT: import-flags
|
|
|
|
- There are some inconsistencies when importing grammars:
|
|
|
|
1. when doing "pg -printer=cfg", one must have used "i -conversion=finite",
|
|
since "pg" doesn't care about the flags that are set in the grammar file
|
|
|
|
2. when doing "pm -printer=cfgm", one must have set the flag
|
|
"conversion=finite" within the grammar file, since "pm" doesn't
|
|
care about the flags to the import command
|
|
|
|
(I guess it's me (peb) who should fix this, but I don't know where
|
|
the different flags reside...)
|
|
|
|
- Also, it must be decided in what cases flags can override other flags:
|
|
|
|
a) in the grammar file, e.g. "flags conversion=finite;"
|
|
b) on the command line, e.g. "> sf conversion=finite"
|
|
c) as argument to a command, e.g. "> i -conversion=finite file.gf"
|
|
|
|
- A related issue is to decide the scope of flags:
|
|
|
|
Some flags are (or should be) local to the module
|
|
(e.g. -coding and -path)
|
|
Other flags override daughter flags for daughter modules
|
|
(e.g. -startcat and -conversion)
|
|
|
|
* [bringert] IMPORTANT: get right startcat flag when printing CFGM
|
|
GF.CFGM.PrintCFGrammar.prCanonAsCFGM currently only gets the startcat
|
|
flag from the top-level concrete module. This might be easier
|
|
to fix if the multi grammar printers had access to more than just
|
|
the CanonGrammar.
|
|
|
|
* [peb] WISH: generalizing incomplete concrete
|
|
|
|
I want to be able to open an incomplete concrete module
|
|
inside another incomplete conrete.
|
|
Then I can instantiate both incompletes at the same time.
|
|
|
|
* [peb] WISH: _tmpi, _tmpo
|
|
|
|
The files _tmpi and _tmpo are never removed when quitting GF.
|
|
Further suggestion: put them in /tmp or similar.
|
|
|
|
peb: när man använder "|" till ett systemanrop, t.ex:
|
|
pg | ! sort
|
|
så skapas filerna _tmpi och _tmpo. Men de tas aldrig bort.
|
|
|
|
peb: Ännu bättre: ta bort filerna efteråt.
|
|
|
|
aarne: Sant: när GF quittas (om detta inte sker onormalt).
|
|
Eller när kommandot har kört färdigt (om det terminerar).
|
|
|
|
peb: Bäst(?): skapa filerna i /tmp eller liknande.
|
|
|
|
aarne: Ibland får man skrivrättighetsproblem - och det är
|
|
inte kul om man måste ange en tmp-path. Och olika
|
|
användare och gf-processer måste ha unika filnamn.
|
|
Och vet inte hur det funkar på windows...
|
|
|
|
aarne: Ett till alternativ skulle vara att använda handles
|
|
utan några tmp-filer alls. Men jag har inte hunnit
|
|
ta reda på hur det går till.
|
|
|
|
björn: Lite slumpmässiga tankar:
|
|
+ man kan använda System.Directory.getTemporaryDirectory, så slipper man iaf bry sig om olika plattformsproblem.
|
|
+ sen kan man använda System.IO.openTempFile för att skapa en temporär fil. Den tas dock inte bort när programmet avslutas, så det får man fixa själv.
|
|
+ System.Posix.Temp.mkstemp gör nåt liknande, men dokumentationen är dålig.
|
|
+ biblioteket HsShellScript har lite funktioner för sånt här, se
|

* [peb] WISH: Hierarchic modules
|
|
|
|
Suggestion by peb:
|
|
The module A.B.C is located in the file A/B/C.gf
|
|
|
|
Main advantage: you no longer need to state "--# -path=..." in
|
|
modules
|
|
|
|
- How can this be combined with several modules inside one file?
