    <p>I use <code>vim</code> (installed on <code>cygwin</code>) to write <code>c++</code> programs but it does not highlight some <code>c++</code> keywords such as <code>new</code>, <code>delete</code>, <code>public</code>, <code>friend</code>, <code>try</code>, but highlight others such as <code>namespace</code>, <code>int</code>, <code>const</code>, <code>operator</code>, <code>true</code>, <code>class</code>, <code>include</code>. It also not change color of operators.</p> <p>I never changed its syntax file. What's wrong with it? Thanks a lot. </p> <p>I use a customized color scheme; when I change it to <code>desert</code> color scheme, highlighting has no problem, but I need to use that color scheme and can't change it to something else.</p> <p>I want it show program as the following picture(I used this color scheme with notepad++ in the picture):</p> <p><img src="https://i.stack.imgur.com/qGIb9.png" alt="example of correctly colored one"></p> <p>but now it's as the following picture: <img src="https://i.stack.imgur.com/anaCh.png" alt="not correctly colored one"></p> <p>the <code>colorscheme</code> is here:</p> <pre><code>"Tomorrow Night Bright - Full Colour and 256 Colour " http://chriskempson.com " " Hex colour conversion functions borrowed from the theme "Desert256"" " Default GUI Colours let s:foreground = "eaeaea" let s:background = "000000" let s:selection = "424242" let s:line = "2a2a2a" let s:comment = "969896" let s:red = "d54e53" let s:orange = "e78c45" let s:yellow = "e7c547" let s:green = "b9ca4a" let s:aqua = "70c0b1" let s:blue = "7aa6da" let s:purple = "c397d8" let s:window = "4d5057" set background=dark hi clear syntax reset let g:colors_name = "Tomorrow-Night-Bright" if has("gui_running") || &amp;t_Co == 88 || &amp;t_Co == 256 " Returns an approximate grey index for the given grey level fun &lt;SID&gt;grey_number(x) if &amp;t_Co == 88 if a:x &lt; 23 return 0 elseif a:x &lt; 69 return 1 elseif a:x &lt; 103 return 2 elseif a:x &lt; 127 return 3 elseif a:x &lt; 150 return 4 elseif a:x &lt; 173 return 5 elseif a:x &lt; 196 return 6 elseif a:x &lt; 219 return 7 elseif a:x &lt; 243 return 8 else return 9 endif else if a:x &lt; 14 return 0 else let l:n = (a:x - 8) / 10 let l:m = (a:x - 8) % 10 if l:m &lt; 5 return l:n else return l:n + 1 endif endif endif endfun " Returns the actual grey level represented by the grey index fun &lt;SID&gt;grey_level(n) if &amp;t_Co == 88 if a:n == 0 return 0 elseif a:n == 1 return 46 elseif a:n == 2 return 92 elseif a:n == 3 return 115 elseif a:n == 4 return 139 elseif a:n == 5 return 162 elseif a:n == 6 return 185 elseif a:n == 7 return 208 elseif a:n == 8 return 231 else return 255 endif else if a:n == 0 return 0 else return 8 + (a:n * 10) endif endif endfun " Returns the palette index for the given grey index fun &lt;SID&gt;grey_colour(n) if &amp;t_Co == 88 if a:n == 0 return 16 elseif a:n == 9 return 79 else return 79 + a:n endif else if a:n == 0 return 16 elseif a:n == 25 return 231 else return 231 + a:n endif endif endfun " Returns an approximate colour index for the given colour level fun &lt;SID&gt;rgb_number(x) if &amp;t_Co == 88 if a:x &lt; 69 return 0 elseif a:x &lt; 172 return 1 elseif a:x &lt; 230 return 2 else return 3 endif else if a:x &lt; 75 return 0 else let l:n = (a:x - 55) / 40 let l:m = (a:x - 55) % 40 if l:m &lt; 20 return l:n else return l:n + 1 endif endif endif endfun " Returns the actual colour level for the given colour index fun &lt;SID&gt;rgb_level(n) if &amp;t_Co == 88 if a:n == 0 return 0 elseif a:n == 1 return 139 elseif a:n == 2 return 205 else return 255 endif else if a:n == 0 return 0 else return 55 + (a:n * 40) endif endif endfun " Returns the palette index for the given R/G/B colour indices fun &lt;SID&gt;rgb_colour(x, y, z) if &amp;t_Co == 88 return 16 + (a:x * 16) + (a:y * 4) + a:z else return 16 + (a:x * 36) + (a:y * 6) + a:z endif endfun " Returns the palette index to approximate the given R/G/B colour levels fun &lt;SID&gt;colour(r, g, b) " Get the closest grey let l:gx = &lt;SID&gt;grey_number(a:r) let l:gy = &lt;SID&gt;grey_number(a:g) let l:gz = &lt;SID&gt;grey_number(a:b) " Get the closest colour let l:x = &lt;SID&gt;rgb_number(a:r) let l:y = &lt;SID&gt;rgb_number(a:g) let l:z = &lt;SID&gt;rgb_number(a:b) if l:gx == l:gy &amp;&amp; l:gy == l:gz " There are two possibilities let l:dgr = &lt;SID&gt;grey_level(l:gx) - a:r let l:dgg = &lt;SID&gt;grey_level(l:gy) - a:g let l:dgb = &lt;SID&gt;grey_level(l:gz) - a:b let l:dgrey = (l:dgr * l:dgr) + (l:dgg * l:dgg) + (l:dgb * l:dgb) let l:dr = &lt;SID&gt;rgb_level(l:gx) - a:r let l:dg = &lt;SID&gt;rgb_level(l:gy) - a:g let l:db = &lt;SID&gt;rgb_level(l:gz) - a:b let l:drgb = (l:dr * l:dr) + (l:dg * l:dg) + (l:db * l:db) if l:dgrey &lt; l:drgb " Use the grey return &lt;SID&gt;grey_colour(l:gx) else " Use the colour return &lt;SID&gt;rgb_colour(l:x, l:y, l:z) endif else " Only one possibility return &lt;SID&gt;rgb_colour(l:x, l:y, l:z) endif endfun " Returns the palette index to approximate the 'rrggbb' hex string fun &lt;SID&gt;rgb(rgb) let l:r = ("0x" . strpart(a:rgb, 0, 2)) + 0 let l:g = ("0x" . strpart(a:rgb, 2, 2)) + 0 let l:b = ("0x" . strpart(a:rgb, 4, 2)) + 0 return &lt;SID&gt;colour(l:r, l:g, l:b) endfun " Sets the highlighting for the given group fun &lt;SID&gt;X(group, fg, bg, attr) if a:fg != "" exec "hi " . a:group .

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
