Text can be aligned to either left or + right margin or justified to both margins or centered. The + text formatting commands in this plugin are a bit different + from those integrated to Vim. + +Author Teemu Likonen + + + + +Contents + + 1. Quick start |textformat-start| + 2. Commands |textformat-commands| + 3. Default key mappings |textformat-keymap-default| + 4. User key mappings |textformat-keymap-user| + +============================================================================== +1. Quick start *textformat-start* + +The impatient ones are always with us so here is the list of (probably) the +most commonly used key mappings for formatting text: + + al Reformat current paragraph and align lines to the + left. + ar Align lines of current paragraph to the right. + aj Reformat current paragraph and justify it to both + margins. The last line in the paragraph is aligned to + the left. + ac Center lines of current paragraph. + +By default, is the backslash key (\) so by default the mappings are +actually \al, \ar, \aj and \ac. If you have changed the g:mapleader variable +in your .vimrc file may be something else. + +============================================================================== +2. Commands *textformat-commands* + +Let's start with the basic components of this plugin. These are the ex +commands. You probably don't need these very often but they can be handy if +you want to have text formatting and aligning as a part of a macro or function +or something. The "daily tools" are explained later. + +:[range]AlignLeft [indent] *:AlignLeft* + Align to left all the lines in [range] (default is + current line) and truncate all extra whitespace + characters. That is, if there are more than one space + between words they are reduced to just one. If + 'joinspaces' is set then two spaces are inserted after + every sentence ending with character ".", "?" or "!". + + If optional numeric argument [indent] is given then + that is used as the left margin. If [indent] is not + given the indent of the first line in the [range] is + used to define indent for the rest of the lines. There + is one exception: if 'formatoptions' contains "2" then + the second line in the [range] defines the indent for + the rest of the lines. + + Note: This is very similar to |:left| command except + that this also truncates whitespaces and that without + [indent] the first line's indent is used. + + Note: There is a possible unexpected behaviour: If + command is run without [range] (i.e., it's just the + current line) and [indent] is not given then this + command just "aligns" to the current indent position + and truncates whitespaces. You might see nothing + happening if there weren't any extra whitespaces. Use + [indent] (or |:left| command) to align to desired + column. + +:[range]AlignRight [width] *:AlignRight* + Align to right all the lines in [range] (default is + current line) and truncate all extra whitespace + characters (honor 'joinspaces', as in :AlignLeft). + [width] is used as the right margin. If [width] is not + given 'textwidth' option is used instead. If + 'textwidth' is zero then the value of 80 is used. + + Note: This is very similar to |:right| command except + that this also truncates whitespaces. + +:[range]AlignJustify [width] *:AlignJustify* + Left-right justify lines in [range] (default is + current line). This means adjusting spaces between + words so that the lines fit. Unlike the previous + commands this does not use 'joinspaces' option. + Instead, extra spaces are always first added after + sentences ending with ".", "?" or "!". Then to other + available positions. + + The first line in the [range] defines the indent for + the rest of the lines, except if 'formatoptions' + contains "2" then it's the second line. + + Numeric argument [width] is used as the right margin. + If [width] is not given 'textwidth' is used instead. + If 'textwidth' is zero then the value of 80 is used. + + Also see the Discussion below. + +:[range]AlignCenter [width] *:AlignCenter* + Center lines in [range] (default is current line) + horizontally between the first column and [width]. All + extra whitespace characters are truncated but honor + 'joinspaces', just like in :AlignLeft. If [width] is + not given 'textwidth' option is used instead. If + 'textwidth' is zero the value of 80 is used. + + Note: This is very similar to |:center| except that + this also truncates whitespaces. + +Discussion ~ + +All previous commands operate on single lines only. They do not wrap lines nor +do other kind of formatting. If [width] (or 'textwidth') is too narrow for the +line then some characters will go beyond the right margin. This is similar to +Vim's own |:left|, |:right| and |:center| commands. You might first want to +adjust line lengths with other editing commands and then run one of the +previous text-formatting commands. + +Usually when paragraphs are justified the last line of paragraph is aligned to +left. However, :AlignJustify command (see above) does not do this. The purpose +of this command is to do exactly what was asked for: left-right justify +a range of lines. The general-purpose justification tools is aj which +reformats the paragraph (like |gw|), justifies lines and aligns the last line +to left. + +Why do these commands truncate whitespaces? Well, this is a text-formatting +tool and in plain text paragraphs any extra spaces are considered +a "typographical flaw." These formatting commands can be used to fix +whitespace errors in plain text. Another reason is that left-right justify +commands need to add extra spaces to make lines fit. If you later want to +reformat such previously justified paragraph and align it to left, for +example, it's convenient that the tool automatically handles this and removes +extra spaces. If you want to align text without truncating whitespaces use +Vim's own align commands: |:left|, |:right| and |:center|. + +============================================================================== +3. Default key mappings *textformat-keymap-default* + +By default this plugin provides a couple of key mappings for convenient text +formatting. If some of the mappings have already been defined by user (or are +taken by some other plugin) then some of the following mappings may not be +automatically available. See the next section of this manual for information +on how to change the default mappings. + +There are key mappings available for normal mode and visual mode. As usual, + is the backslash key by default but it can be changed with +g:mapleader variable. Consult the Vim manual for more information on . + +Normal mode (current paragraph) ~ + +al Left-align current paragraph, truncate all whitespace + characters (but honor 'joinspaces', as in :AlignLeft) + and reformat the paragraph so that it fits to + 'textwidth'. The first line in the paragraph defines + the indent for the rest of the lines, except if + 'formatoptions' contains "2" then it's the second + line. + +ar Right-align current paragraph (use 'textwidth') and + truncate all whitespace characters (but honor + 'joinspaces', as in :AlignLeft). This does not + reformat lines because with right-aligned text user + usually wants to decide exactly what goes to what + line. + +aj Left-right justify. Truncate all whitespace characters + (but honor 'joinspaces', as in :AlignLeft), reformat + the paragraph so that it fits to 'textwidth' and + finally left-right justify lines. Extra spaces may be + added between words so that lines fill the text area. + Paragraph's last line is aligned to left. The first + line in the paragraph defines the indent for the rest + of the lines, except if 'formatoptions' contains "2" + then it's the second line. + +ac Center lines of current paragraph horizontally between + the first column and 'textwidth'. All whitespace + characters are truncated, except if 'joinspaces' is + set then an extra space is added after full sentences + (see :AlignLeft). This does not reformat the + paragraph. With centered text user usually wants to + decide exactly what goes to what line. Reformatting + would destroy it. + +Visual mode (range of lines) ~ + +{Visual}al Left-align {Visual} lines. +{Visual}ar Right-align {Visual} lines. +{Visual}aj Left-right justify {Visual} lines. +{Visual}ac Center {Visual} lines. + +Visual mode mappings do not wrap lines nor otherwise reformat text. They work +line-by-line, just like their command line equivalents: :AlignLeft, +:AlignRight, :AlignJustify and :AlignCenter. + +============================================================================== +4. User key mappings *textformat-keymap-user* + +The key mappings can be configured freely by user. This plugin uses the +default ones only if they are free and not mapped to some other things. We try +to be non-intrusive because this is a general-purpose tool which is likely +loaded automatically when Vim starts. + +Here's an example of lines you could put in your .vimrc file: > + + nmap Quick_Align_Paragraph_Left + nmap Quick_Align_Paragraph_Right + nmap Quick_Align_Paragraph_Justify + nmap Quick_Align_Paragraph_Center + + vmap Align_Range_Left + vmap Align_Range_Right + vmap Align_Range_Justify + vmap Align_Range_Center + +That is, |:nmap| command defines mappings for normal mode and |:vmap| for +visual mode. Function keys from to are used in this example. The +rest of the line is a code word for this plugin; they tell Vim what to do. +I think the code words are pretty much self-descriptive. + +Don't use |:nnoremap| and |:vnoremap| commands here; they don't work because +the right-hand side (...) must be remappable. See Vim's manual for more +information about mapping commands. + +Happy formatting! + +============================================================================== +vim: ft=help tw=78 ts=8 norl diff --git a/.vim/plugin/textformat.vim b/.vim/plugin/textformat.vim new file mode 100644 index 0000000..3ebdc61 --- /dev/null +++ b/.vim/plugin/textformat.vim @@ -0,0 +1,68 @@ +" Text formatter plugin for Vim text editor +" +" This plugin provides commands and key mappings to quickly align and format +" text.
