My problem boils down to that the sequence gulp.src('…').replace('…','…').php2html().htmlmin().gulp.dest('…') is not executing the php2html. No error, but on action either. A control message (console.log) at the beginning of my routine will issue, indicating that the watch fired and called correctly. I attached a question I posted to ChatGpt that describes exactly what I want to do with gulp (but it's answers were of no help).
Here comes my gulpfile, help welcome, please!
// gulpfile.js is in a subdirectory. go to directiory, that is ./ throughout the script:
process.chdir('..');
const gulp = require('gulp'),
htmlmin = require('gulp-htmlmin'),
php2html = require('gulp-php2html'),
replace = require('gulp-replace'),
langs = ['en', 'es', 'ga', 'de']
htmlmin_options = {
// nothing special. scipping these for brevity
},
php2html_options = {
verbose: true,
haltOnError: true,
bin: 'C:/Program Files/php/php.exe'
}
;
function changeLang(lang, cb) {
const isDefaultLang = lang === 'en',
destPath = isDefaultLang ? '../' : `../${lang}/`,
replace_options = { replace: '$curLang="en"',
with: `$curLang="${lang}"` }
;
console.log(`in changeLang2 for ${lang}`);
gulp
.src('./index.php')
.pipe(replace(replace_options.replace,replace_options.with))
.pipe(gulp.dest(destPath));
cb();
}
function php2htmlMinDel(lang, cb) { // not working
const isDefaultLang = lang === 'en',
watchFile = isDefaultLang ? '../index.php' : `../${lang}/index.php`
;
console.log(`in php2htmlMinDel2 for ${lang}`);
gulp
.src(watchFile)
//.pipe(gulp.dest('test/.')); // TEST: Ok, yes, the file stream is ready and complete.
.pipe(php2html(php2html_options))
.pipe(htmlmin(htmlmin_options))
.pipe(gulp.dest('.'));
cb();
}
// TEST: both tasks in one routine: (not working. ChatGpt says reason is that replace is syncronous while php2html is async)
// This is what I would really like to run.
function singleLangChangeLang(lang, cb) {
const isDefaultLang = lang === 'en',
destPath = isDefaultLang ? '../' : `../${lang}/`,
replace_options = { replace: '$curLang="en"',
with: `$curLang="${lang}"` }
;
console.log(`in singleLangChangeLang for ${lang}`);
gulp
.src('./index.php')
.pipe(replace(replace_options.replace,replace_options.with))
.pipe(php2html(php2html_options))
.pipe(htmlmin(htmlmin_options))
.pipe(gulp.dest(destPath));
cb();
}
// TEST: interesting: only htmlmin without php2html: works.
// this is the same construct as with 'php2htmlMinDel' and it works.
// So the problem is not program flow or parameters, but it's with php2html.
function onlyHtmlMinimize(lang, cb) {
// testfile test/test.html:
// <body>
// <!-- comment and cr/lf will be removed. String $curLang="es" to be altered. -->
// <?=$curLang="en";?>
// </body>
const watchFile = 'test/test.html'
replace_options = { replace: '$curLang="en"',
with: `$curLang="${lang}"` }
;
console.log(`in onlyHtmlMinimize for ${lang}`);
gulp
.src(`${watchFile}`)
.pipe(replace(replace_options.replace,replace_options.with))
//.pipe(php2html(php2html_options))
.pipe(htmlmin(htmlmin_options))
.pipe(gulp.dest('test/changed/.'));
cb();
}
// HERE COME ALL THE TASKS AND TESTS:
gulp.task('watch', function (done) {
// 1. lang/lang_strs_….json SINGLE language file change:
// This is split in two parts:
// 1.) changeLang: take ./index.php and replace the language string. Write new index.php to ${lang} directory.
// 2.) Watch ${lang} directories for new/changed index.php file, php2html convert it, minimize it, write back to same directory as index.html
// Reason: replace() followed by php2html() in same task doesn't work, because former is a synchrounos task while latter is asysc (thats what ChatGpt says)
langs.forEach(lang => {
gulp.watch( [`./lang/lang_strs_${lang}.json`] ,
gulp.series(
changeLang.bind(null, lang), // ok
php2htmlMinDel.bind(null, lang) // doing nothing
));
});
// 2.) On ./*.PHP change: do the langTask for ALL languages:
gulp.watch( ['*.php'] , gulp.series(
langs.map(lang => changeLang.bind(null, lang)), // ok. produces .php with changed string
langs.map(lang => php2htmlMinDel.bind(null, lang)) // Not working: doesn't produce .html
));
// TEST: do the above in one routine: (change globs to try)
gulp.watch( ['*.phpXXX'] , gulp.series(
langs.map(lang => singleLangChangeLang.bind(null, lang))
));
// TEST: does php2html work at all? => Yes, working ok.
gulp.watch('test/test.php', function php2HtmlTest () {
return gulp
.src('test/test.php')
.pipe(php2html(php2html_options))
.pipe(gulp.dest('test/.'));
});
// TEST: with same construct like php2htmlMinDel, onlyHtmlMinimize works:
// (to try, manually create test/test.html)
gulp.watch('test/test.html', gulp.series(
onlyHtmlMinimize.bind(null, 'xx')
));
done();
});
