JADE - generate-keywords.cc

[AIR]

I originally used BASH with the 'ack' program to generate the Keywords.txt and Prototypes.txt files for Jade.

Problem was that 'ack' is a 3rd party program which isn't typically installed on Linux/macOS machines (I don't even know if there's a version for Windows, to be honest).

I rewrote the script using Python, but while it typically comes pre-installed on Linux/macOS, it definitely is not pre-installed on Windows.

Rather than require the installation on OS's that don't have Python installed, I decided to re-write the generate-keywords using Jade itself.

Here is what it looks like, feedback is encouraged!!!

Code: C

1. #include "jade.h"

16. SUB jadeKeywordProto(STRING srcFile,STRING query, STRARRAY& sarray) BEGIN
17.     REGQUERY term(query);
18.     STRING src(LOADFILE$(srcFile));
19.     std::sregex_token_iterator it(src.begin(), src.end(), term,2);
20.  
21.     WHILE ( it != std::sregex_token_iterator() ) BEGIN
22.         IF ( NOT it->str().empty() && it->str() != " "  ) THEN
23.             sarray.push_back(it->str());
24.         ENDIF
25.         it++;
26.     WEND
27. END
28.  
29.  
30. MAIN
31.     STRARRAY KEYWORDS,PROTOTYPES;
32.  
33.     jadeKeywordProto("runtime.inc", "(FUNCTION|SUB) (.+\\)) BEGIN", PROTOTYPES);
34.     jadeKeywordProto("header.inc", "(#define\\s+|typedef .+ )(\\w+\\$|\\w+)", KEYWORDS);
35.     jadeKeywordProto("runtime.inc", "(FUNCTION .+ |SUB|SUB )(\\w+|\\w+\\$) \\(.+ BEGIN", KEYWORDS);
36.  
37.     OUTFILE keyFile("KEYWORDS.txt");
38.     FOR (VAR item IN KEYWORDS) BEGIN
39.         keyFile << item << std::endl;
40.     END
41.  
42.     OUTFILE protoFile("PROTOTYPES.txt");
43.     FOR (VAR item IN PROTOTYPES) BEGIN
44.         protoFile << item << std::endl;
45.     END    
46.  
47. ENDMAIN
48.  
49.  

Keep in mind that this is C++; I didn't use DIM, etc because it's redundant with my Jade implementation, and just clutters things up.

feedback is encouraged!!!

I would like to see JADE hide variable typing altogether. (like SB)

While on the SB topic, have you thought about using SB to generate your JADE keywords?

[AIR]

For example?

No, that's an additional dependency, which I'm trying to avoid.  Otherwise, I would have just stayed with Bash/Ack or Python.

But you're more than welcome to give it a try in SB, if you like.

Because JADE is not using a Parser/Lexer like SB is (JADE uses the c++ preprocessor for a lot of stuff), doing it like you ask isn't possible.

Doesn't mean I can't duplicate what your output is, though, with only a single explicit declaration (for the array):

Code: C

1. #include "jade.h"
2.  
3.  
4. MAIN
5.     VAR a=1;
6.     VAR b="2";
7.     ARRAY<double>c(1000001, .3);
8.  
9.     PRINT(a+VAL(b));
10.     PRINT(a,b);
11.     PRINT(c[1000000]);
12. END
