A gawk script to convert smart quotes
======
@@ -16,175 +17,96 @@ You can use different methods to convert quotes. Greg Pittman wrote a [Python sc
To start, I wrote a simple gawk function to evaluate a single character. If that character is a quote, the function determines if it should output a plain quote or a smart quote. The function looks at the previous character; if the previous character is a space, the function outputs a left smart quote. Otherwise, the function outputs a right smart quote. The script does the same for single quotes.
```
function smartquote (char, prevchar) {
-
# print smart quotes depending on the previous character
-
# otherwise just print the character as-is
-
-
if (prevchar ~ /\s/) {
-
# prev char is a space
-
if (char == "'") {
-
printf("‘");
-
}
-
else if (char == "\"") {
-
printf("“");
-
}
-
else {
-
printf("%c", char);
-
}
-
}
-
else {
-
# prev char is not a space
-
if (char == "'") {
-
printf("’");
-
}
-
else if (char == "\"") {
-
printf("”");
-
}
-
else {
-
printf("%c", char);
-
}
-
}
-
}
-
```
With that function, the body of the gawk script processes the HTML input file character by character. The script prints all text verbatim when inside an HTML tag (for example, ``. Outside any HTML tags, the script uses the `smartquote()` function to print text. The `smartquote()` function does the work of evaluating when to print plain quotes or smart quotes.
```
function smartquote (char, prevchar) {
-
...
-
}
-
-
BEGIN {htmltag = 0}
-
-
{
-
# for each line, scan one letter at a time:
-
-
linelen = length($0);
-
-
prev = "\n";
-
-
for (i = 1; i <= linelen; i++) {
-
char = substr($0, i, 1);
-
-
if (char == "<") {
-
htmltag = 1;
-
}
-
-
if (htmltag == 1) {
-
printf("%c", char);
-
}
-
else {
-
smartquote(char, prev);
-
prev = char;
-
}
-
-
if (char == ">") {
-
htmltag = 0;
-
}
-
}
-
-
# add trailing newline at end of each line
-
printf ("\n");
-
}
-
```
Here's an example:
```
gawk -f quotes.awk test.html > test2.html
