I wonder why it didn't allow me specify something like "<font face="courier new, courier, monaco, monospace, sans-serif">^[TRUE|FALSE]$</font>" or "<font face="courier new, courier, monaco, monospace, sans-serif">^TRUE|FALSE$</font>" to validate a boolean value but "^[A-Z]{4,5}$".</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">However, I don't know if it's possible to define some well-known regex flags in code like "<font face="courier new, courier, monaco, monospace, sans-serif">[:INTEGER:]</font>" for "<font face="courier new, courier, monaco, monospace, sans-serif">^[0-9]+$</font>", "<font face="courier new, courier, monaco, monospace, sans-serif">[:DOUBLE:]</font>" for "<font face="courier new, courier, monaco, monospace, sans-serif">^[0-9]+[.][0-9]+$</font>" or "<font face="courier new, courier, monaco, monospace, sans-serif">[:BOOLEAN:]</font>" for "<font face="courier new, courier, monaco, monospace, sans-serif">^[TRUE|FALSE]$<span><font style="background-color: inherit;" face="Helvetica Neue, Helvetica, Arial, sans-serif">" or "</font>^</span>[tT|fF]$</font>". I understand that leaving it open is more flexible and it's ok, but perhaps adding these flags can be easier to use. I don't know, what do you think ?</div><div dir="ltr" data-setdir="false"><br></div><div><br></div><div><br></div><div class="ydp409447ffsignature" dir="ltr" data-setdir="false"><font style="font-weight:bold;color:rgb(0, 96, 191);font-family:verdana, helvetica, sans-serif;" size="2">MSc.
