Is there a better (more modern) tool than lex/flex for generating a tokenizer for C++?

断了今生、忘了曾经 提交于 2019-12-02 17:12:23
I recent added source file parsing to an existing tool that generated output files from complex command line arguments. The command line arguments got to be so complex that we started allowing them to be supplied as a file that was parsed as if it was a very large command line, but the syntax was still awkward. So I added the ability to parse a source file using a more reasonable syntax. I used flex 2.5.4 for windows to generate the tokenizer for this custom source file format, and it worked. But I hated the code. global variables, wierd naming convention, and the c++ code it generated was

How to tokenize a extended macro (local :dir )?

问题 I know my title is confusing in the sense that the tokenize command is specified to a string. I have many folders that contain massive, separated, ill-named Excel files (most of them are scraped from ahe website). It's inconvenient to select them manually so I need to rely on Stata extended macro function local :dir to read them. My code looks as follows: foreach file of local filelist { import excel "`file'", clear sxpose, clear save "`file'.dta", replace } Such code will generate many new

Can a line of Python code know its indentation nesting level?

可紊 提交于 2019-12-02 14:46:05
From something like this: print(get_indentation_level()) print(get_indentation_level()) print(get_indentation_level()) I would like to get something like this: 1 2 3 Can the code read itself in this way? All I want is the output from the more nested parts of the code to be more nested. In the same way that this makes code easier to read, it would make the output easier to read. Of course I could implement this manually, using e.g. .format() , but what I had in mind was a custom print function which would print(i*' ' + string) where i is the indentation level. This would be a quick way to make

How to make the tokinezer detect empty spaces while using strtok()

假装没事ソ 提交于 2019-12-02 13:22:45
I am designing a c++ program, somewhere in the program i need to detect if there is a blank(empty token) next to the token used know eg. if(token1==start) { token2=strtok(NULL," "); if(token2==NULL) {LCCTR=0;} else {LCCTR=atoi(token2);} so in the previous peice token1 is pointing to start , and i want to check if there is anumber next to the start , so I used token2=strtok(NULL," ") to point to the next token but unfortunattly the strtok function cannot detect empty spaces so it gives me an error at run time"INVALID NULL POINTER" how can i fix it or is there another function to use to detect

Converting Readability formula into python function

六眼飞鱼酱① 提交于 2019-12-02 09:54:38
I was given this formula called FRES (Flesch reading-ease test) that is used to measure the readability of a document: My task is to write a python function that returns the FRES of a text. Hence I need to convert this formula into a python function. I have re-implemented my code from a answer I got to show what I have so far and the result it has given me: import nltk import collections nltk.download('punkt') nltk.download('gutenberg') nltk.download('brown') nltk.download('averaged_perceptron_tagger') nltk.download('universal_tagset') import re from itertools import chain from nltk.corpus

Need to know how to parse words by space in c. Also need to know if I am allocating memory correctly?

三世轮回 提交于 2019-12-02 09:03:17
问题 I am writing a program in c that reads in text from a text file then randomly selects words from the file and if the words are greater than or equal to six it appends the words together, removes the spaces, and finally prints the new word. (I am using the redirect on linux "<" to read in the file) Example input: "cheese and crackers" New word should be: cheesecrackers Here is the code: int main (void) { int ch; char *ptrChFromFile; int strSize = 1; int i; int numberOfWords = 1; ptrChFromFile

Token with different interpretations (i.e. keyword and identifier)

十年热恋 提交于 2019-12-02 08:07:09
问题 I am writing a grammar with a lot of case-insensitive keywords in ANTLR4. I collected some example files for the format, that I try to test parse and some use the same tokens which exist as keywords as identifiers in other places. For example there is a CORE keyword, which in other places is used as a ID for a structure from user input. Here some parts of my grammar: fragment A : [aA]; // match either an 'a' or 'A' fragment B : [bB]; fragment C : [cC]; [...] CORE: C O R E ; [...] IDSTRING: [a

Python Tokenization

天大地大妈咪最大 提交于 2019-12-02 05:56:11
I am new with Python and I have a Tokenization assignment The Input is a .txt file with sentences and output is .txt file with Tokens, and When I say Token i mean: simple word, ',' , '!' , '?' , '.' ' " ' I have this function: Input: Elemnt is a word with or without Punctuation, could be word like: Hi or said: or said" StrForCheck : is an array of Punctuation that i want to separate from the words TokenFile: is my output file def CheckIfSEmanExist(Elemnt,StrForCheck, TokenFile): FirstOrLastIsSeman = 0 for seman in StrForCheck: WordSplitOnSeman = Elemnt.split(seman) if len(WordSplitOnSeman) > 1

Elasticsearch custom analyzer with ngram and without word delimiter on hyphens

梦想的初衷 提交于 2019-12-02 05:43:44
问题 I am trying to index strings that contain hyphens but do not contain spaces, periods or any other punctuation. I do not want to split up the words based on hyphens, instead I would like to have the hyphens be part of the indexed text. For example, my 6 text strings would be: magazineplayon magazineofhorses online-magazine best-magazine friend-of-magazines magazineplaygames I would like to be able to search these string for the text containing "play" or for the text starting with "magazine" .
