[I7] Extending maximun words for read

Authoring Inform 7
1

Hi!
I found that MAX_BUFFER_WORDS set the limit count of words that the Gmachine could receive.
I need to extend that limit (now in 20 til, says 50) not for parse-process but for the “say” command (for use it in multiplayer context).

I put
MAX_BUFFER_WORDS = 50

but, in tests, when I write a long text-command I get this git fail:

[** Programming error: tried to read from –>65 in the array “parse”>

It seems that there is a relation between MAX_BUFFER_WORDS and PARSE_BUFFER_LEN.
Any help?

Thanx.

According to my notes, PARSE_BUFFER_LEN should be (MAX_BUFFER_WORDS*3)+1.

3

Is it possible to just define the constant that way? I know the C preprocessor collapses arithmetic like that in macros, but I don’t know if Inform 6 does.

4

It does. Probably that’s what should have been done.

many thanx Zarf.

I did the fixes and works fine!

-) instead of “Variables and Arrays” in “Glulx.i6t”.[/spoiler]

but, there is another ‘obstacle’: my WIP use the “change the text of the player’s command to…” (SetPlayersCommand sub in IndexedText.i6t) after change the player (that makes sense in multiplayer context) .
The case is that SetPlayersCommand truncates the buffer in 118 max chars, and then the player “tell something long-verbose-text…” command produces a truncated text. I disabled that limit and it seems work fine.

Is there any side effect?

I don’t know why SetPlayersCommand uses a hardwired limit. You shouldn’t remove the limit entirely, but it should be based on the array size, which for Glulx is (INPUT_BUFFER_LEN-WORDSIZE)-1.

Also be sure that you change the “120” farther down the function to the same length limit. (Filling the buffer with spaces shouldn’t be necessary, but as long as the function does it, it should do it sensibly.)

ok, thank you very much!
