Pātai auau

He aha ngā hoa regex e tautokohia ana?

JavaScript (taunoa), PCRE-hāngai, me POSIX. Ka tohua ngā āhuatanga kāore e tautokohia ina huri koe i ngā hoa.

Ka wehe tō aho whakamātau i te pūtirotiro?

Kāo. Kei te taha-kiritaki katoa; kāore mātou e tuku i tō regex, i ō aho whakamātau rānei ki tētahi tūmau, ki te kore koe e kōwhiri ki te whakarite kapua i ō tauira kua tiakina.

Ka taea te whakamārama i tētahi regex kāore i tuhia e koe?

Āe — koinei te mahi a te kaiwhakamārama. Piri i tētahi regex, ka whiwhi i tētahi wāwāhi ā-taahiraa mā te reo māmā.

Ka whiwhi whakamātau kore utu ahau?

Kāo — he taputapu utu tēnei me ngā mahere mai i te $5 ia marama. Ko te Starter he $5/marama, ā, ko te Pro he $15/marama; ka taea te whakakore i ahuareka.

Me pēhea te whakakore?

Mai i tō whārangi pūkete, mā te tuku īmēra rānei ki a mātou. Ka mutu te whakahou e whai ake nei ina whakakorehia.

Kaua e whakapae mēnā ka hāngai te regex.
