TXT2HTML in C language?


Hello,

It is really simple to convert txt to html, since basically it needs to be added <br> at the end of line and also to
make sure that the special chars of html such as '<', '>', tab,... will be converted to be seen with the HTML document.
https://www.w3schools.com/html/html_entities.asp

There is txt2html but it is still a large project, and it does not work always.

Would you know an efficent txt2html which would do the trick relatively simply?

Thank you

Hi Xeratul,

I've never seen a text-to-HTML converter that keeps tabs. Special characters like > and < should work in text2html. However, I did spot this on the txt2html website:

Quote:
txt2html is not a program to convert wordprocessor files or other marked-up document formats.
This page about HTML indenting is an interesting read. The author summarizes that the best way to get tabs/indenting is using CSS. I presume using CSS is beyond the scope of what you're trying to achieve?

Then again I'm not a web developer lol. I'll have another look a bit later. If I find a converter that parses tabs and special characters I'll let you know.

Thank you !!

Perl is not possible, I would be glad to find it in C since it must have been done already in C.
HTML is since some time about 1985 so that must exist, I am sure.

I look for a better efficient alternative to the one here: https://packages.debian.org/search?keywords=txt2html

You're welcome.

Have you seen this thread? jschiwal proposed a solution using sed. Granted it's an ancient thread over a decade old, but it might be worth having a look.

Also if you want an indent/tab, apparently you can use &emsp; to achieve this. For example:

Code:
&emsp;Check out my awesome indented line of text!<br />
I wonder if it's possible to automate replacing tabs with &emsp; instead? Maybe a bash script or something?

The only other alternatives I can find are online-based text-to-HTML converters...but your mileage may vary.

1)) the HTML looks not easy to handle, man, so complicateed with all thsoe &&& and convertions


2)) I must believe that with simple fd and adaption it is much much efficient and better than an heavy bloat using Perl or bash pipes

Code:

///// some cat!! 
#include <fcntl.h>
#include <unistd.h>
static int cat_fd(int fd) 
{
  char buf[4096];
  ssize_t nread;

  while ((nread = read(fd, buf, sizeof buf)) > 0) 
  {
    ssize_t ntotalwritten = 0;
    while (ntotalwritten < nread) {
      ssize_t nwritten = write(STDOUT_FILENO, buf + ntotalwritten, nread - ntotalwritten);
      if (nwritten < 1)
        return -1;
      ntotalwritten += nwritten;
    }
  }

  return nread == 0 ? 0 : -1;
}

static int ncat_static(const char *fname) {
  int fd, success;
  if ((fd = open(fname, O_RDONLY)) == -1)
    return -1;

  success = cat_fd(fd);

  if (close(fd) != 0)
    return -1;

  return success;
}

simple fd will not influence the complexity of the text/html. Also perl is very good at text processing, and also it has a lot of libraries (already available) to handle html pages. Do not need to reinvent the wheel.
I have no idea how bash pipes are related to it?
