Custom statement fails to register\be recognized

#1 Post by Pyr0 » Tue Aug 08, 2017 9:34 am

I have a file called 01statements.rpy which includes the following python code:

Code: Select all

init python:
        
    def appendParse(lexer):
        textToAppend = lexer.string();
        return textToAppend
        
    def appendExecute(textToAppend):
        narrator(textToAppend)
        ReadLastEntry()
    
    renpy.register_statement("append", parse = appendParse, execute = appendExecute)
My start label is in the file main.rpy:

Code: Select all

label start:
    append "I am appending this text."
When the append statement is executed, this error is displayed:

Code: Select all

[code]
I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/main.rpy", line 2, in script
    append "I am appending this text."
Exception: Sayer 'append' is not defined.

    who = eval_who(self.who, self.who_fast)
  File "C:\Users\My Name\Desktop\Ren'py\renpy\ast.py", line 509, in eval_who
    raise Exception("Sayer '%s' is not defined." % who.encode("utf-8"))
Exception: Sayer 'append' is not defined.

If I try with a different code:

Code: Select all

label start:
    "hello"
    append "there"


The error becomes:

Code: Select all

I'm sorry, but an uncaught exception occurred.

It seems that my file either gets confused for a say statement or is simply not recognized at all. Even copying and pasting the smartline example directly from the documentation doesn't work, it seems like it recognizes the "line" statement but it still wants the dialogue formatted as a string as usual.

Usually you put this in a "python early:" block, but I tried the example here: https://www.renpy.org/doc/html/cds.html#example
and it doesn't work either, looks like renpy.register_statement isn't working atm.

btw. maybe using "extend" ?

Code: Select all

label start:
    extend "I am appending this text."

Extend is not quite the same thing I need, I've modified the screen so that it includes a viewport and I wanted to make a few custom statements to control its vertical bar (in this case, append makes the bar jump to the bottom so you don't have to scroll yourself).

Anyway, yep, I feared it was a bug with ren'py itself.

I tried it in a 01test.rpy with a python early hide: block and had some failures...

Swapped it to a 000test.rpy and am pretty sure it still failed and then, maybe after a delete persistent or full refresh, it suddenly started working and now works fine... odd

btw, on the initial post... using a very basic version with a renpy.say, it works fine here...

000test.rpy

Code: Select all

python early hide:

    def parse_cds(lex):
        return lex.string()

    def execute_cds(o):
        renpy.say("Nobody", o)

    def predict_cds(p):
        return [ ]

    def lint_cds(o):
        pass

    renpy.register_statement('test_cds',
                              parse=parse_cds,
                              execute=execute_cds,
                              predict=predict_cds,
                              lint=lint_cds)
script.rpy

Code: Select all

label start:
    "start"
    test_cds "arg"
    "end"

I revoke my statement that it isn't working, cause I did the noob mistake and put the python early block in my script.rpy, so yeah it is actually working for me as well
with 6.99.12.4.2187 and latest nightly build....

Using a python early block and it fixed it for me as well. My confusion stemmed from the fact that I thought it said "an early python" block (that is, an init). The "early" modifier for the python statement is also not described at all where it should be. All in all I am just happy to have got it to work, thanks everybody.
