Introduction + *vietnamese-intro* +Vim supports Vietnamese language in the following ways: + +- Built-in |vietnamese-keymap|, which allows you to type Vietnamese characters + in |Insert-mode| and |search-commands| using US keyboard layout. +- Localization in Vietnamese. See |vietnamese-l10n| + +=============================================================================== +2. Vietnamese keymaps + *vietnamese-keymap* +To switch between languages you can use your system native keyboard switcher, +or use one of the Vietnamese keymaps included in the Vim distribution, like +below > + :set keymap=vietnamese-telex_utf-8 +< +See |'keymap'| for more information. + +In the latter case, you can type Vietnamese even if you do not have a +Vietnamese input method engine (IME) or you want Vim to be independent from a +system-wide keyboard settings (when |'imdisable'| is set). You can also |:map| +a key to switch between keyboards. + +Vim comes with the following Vietnamese keymaps: +- *vietnamese-telex_utf-8* Telex input method, |UTF-8| encoding. +- *vietnamese-viqr_utf-8* VIQR input method, |UTF-8| encoding. +- *vietnamese-vni_utf-8* VNI input method, |UTF-8| encoding. + + *vietnamese-ime_diff* +Since these keymaps were designed to be minimalistic, they do not support all +features of the corresponding input methods. The differences are described +below: + +- You can only type each character individually, entering the base letter first + and then the diacritics later. For example, to type the word `nến` using + |vietnamese-vni_utf-8|, you must type `ne61n`, not `nen61` or `ne6n1` +- For characters with more than 1 diacritic, you need to type vowel mark before + tone mark. For example, to type `ồ` using |vietnamese-telex_utf-8|, you need + to type `oof`, not `ofo`. +- With |vietnamese-telex_utf-8|, you need to type all uppercase letters to + produce uppercase characters with diacritics. For example, `Ừ` must be typed + as `UWF`. +- With |vietnamese-telex_utf-8|, the escape character `\` from VNI is added, + hence the confusing `ooo` input to type `oo` is removed, which could lead to + ambiguities. For example, to type the word `Đoòng`, you would type + `DDo\ofng`. +- Simple Telex (both v1 and v2), including the `w[]{}` style, is not + supported. +- Removing diacritics using `z` in Telex or `0` in VNI and VIQR is not supported. + +=============================================================================== +3. Localization + *vietnamese-l10n* +Vim |messages| are also available in Vietnamese. If you wish to see messages +in Vietnamese, you can run the command |:language| with an argument being the +name of the Vietnamese locale. For example, > + :language vi_VN +< or > + :language vi_VN.utf-8 +< +Note that the name of the Vietnamese locale may vary depending on your system. +See |mbyte-first| for details. + +=============================================================================== +vim:tw=78:ts=8:noet:ft=help:norl: |
