So I want to have 2 input feilds, one editable. I need some script that would turn such shader text input:
#ifdef GL_ES
precision highp float;
#endif
varying vec4 v_color;
void main (void)
{
gl_FragColor = v_color;
}
into such output:
"#ifdef GL_ES\n"
"precision highp float;\n"
"#endif\n"
"\n"
"varying vec4 v_color;\n"
"\n"
"void main (void)\n"
"{\n"
" gl_FragColor = v_color; \n"
"}"
(such output can be turned into openGL shader static char* )
So how to create such simple tool with Javascript?
try regular expressions.
html:
<textarea id="text1">#ifdef GL_ES
precision highp float;
#endif
varying vec4 v_color;
void main (void)
{
gl_FragColor = v_color;
}
</textarea>
<textarea id="text2"></textarea>
javascript:
var text = document.getElementById("text1").value;
text = text.replace(/\n/g, "\\n\"\n\"");
document.getElementById("text2").value = "\""+text+"\\n\"";
