Ignore one "misspelling" in Vim - vim

Is there a way to tell Vim not to highlight a word once? For example, in "the password is abc123", I don't want to add abc123 to the wordlist, but still wouldn't like the big red rectangle around it.
Clarification: I'm looking for a command that makes the spell checker ignore the current word (or last misspelling).

Without having the word stored somewhere, it's hard (not to say impossible) to ignore it always.
But, if you are looking to ignore the word really once, that is only for a moment, you can add it to the internal list with the zG command.
*zG*
zG Like "zg" but add the word to the internal word list
|internal-wordlist|.
*internal-wordlist*
The internal word list is used for all buffers where 'spell' is set. It is
not stored, it is lost when you exit Vim. It is also cleared when 'encoding'
is set.

When your cursor is positioned on a word that is highlighted as misspelled you can add it to your wordlist by pressing zg. Vim allows you to load more than one wordlist at a time, which makes it possible to have (for example) a global wordlist, and a project specific wordlist.
By default, when you run zg it will add the current word to the first spellfile it finds in your runtime path for the current encoding. In my case, that turns out to be ~/.vim/spell/en.utf-8.add when I'm working with UTF-8 encoding. Try running the following commands:
:setlocal spellfile+=~/.vim/spell/en.utf-8.add
:setlocal spellfile+=oneoff.utf-8.add
That will set you up so that zg (or 1zg) adds the current word to your default spellfile. But running 2zg would add the current word to a file called oneoff.utf-8.add, in the same directory as the file that you are working on. If the file doesn't exist, Vim will try to create it for you.
When you open the file again in the future, you will have to run the same two commands to make Vim check the oneoff.utf-8.add spellfile. Unfortunately, Vim does not allow you to set the spellfile option in a modeline, so if you want to run these commands automatically when the file opens, you would have to find some other way. This question includes a few ideas on how you might proceed.

How to force vim spellchecker to ignore lowercase/uppercase errors

I found here and here how to force Vim spell checker to ignore words with capital letters from being check. But my case is quite opposite. I want to ignore words that in corrected form include capital letters.
So in sentence:
europe was chozen best
only word chozen is the wrong one.
How to achieve that?
Thanks for any hint.
This answer was posted first by Rich on vi&vim stackexchange:
I don't think that Vim has a setting for this. One workaround is to
create a new spellfile that contains everything in your current spell
file(s) but with lowercase letters only:
Create a new buffer containing everything from the spell file(s) currently in use:
:spelldump
Delete lines that don't contain any upper-case characters. This isn't strictly necessary, but there's no point keeping duplicate
entries for lower-case words:
:v/\u/d
Convert the entire file to lower-case, ignoring lines that contain the locations of the spell files:
:v/^#/norm gu$
Save the file:
:w ~/.vim/spell/lowercase.utf-8.add
Start using this file in addition to the standard files in Vim's $VIMRUNTIME directory. Note that Vim uses a default 'spellfile'
value internally if the setting is empty, so if you already have any
existing spell files, you will need to ensure that they are included
in this setting (which accepts a comma-delimited list):
:set spellfile=~/.vim/spell/lowercase.utf-8.add
Note that if you set this option in a running instance of Vim, it
doesn't seem to take effect for spell-checking until you interact with
it (by, e.g. using the zg command.)
The above doesn't affect the way that Vim detects lower-case words at
the start of a sentence as spelled incorrectly. You can disable this
with the 'spellcapcheck' option:
:set spellcapcheck=

Spellchecking in Vim - tell Vim that this is okey

Yes, that title is the best I could come up with :-)
I have a text, and when activating spellchecking naturally a lot of words come out highlighted. Like emails, adresses, names and so on. How to tell Vim that some word is okey, without adding it to the wordlist.
Meaning, just, while editing this document I don't want to see my name highlighted.
Try: zG
:help internal-wordlist
From http://vimdoc.sourceforge.net/htmldoc/spell.html
zg Add word under the cursor as a good word to the first
name in 'spellfile'. A count may precede the command
to indicate the entry in 'spellfile' to be used. A
count of two uses the second entry.
In Visual mode the selected characters are added as a
word (including white space!).
When the cursor is on text that is marked as badly
spelled then the marked text is used.
Otherwise the word under the cursor, separated by
non-word characters, is used.
If the word is explicitly marked as bad word in
another spell file the result is unpredictable.
I have my Vim config in a git repository, which is useful for several things; For example, you could alias your vim to a small script that invokes Vim normally, but after Vim finishes checks if the ~/.vim/spell directory has any modifications and if so, asks you if you want to keep or discard them. If you want to keep them, it could automatically commit everything in spell and otherwise reset everything in there. So you usually wont be bothered by that script unless you actually do use the spellchecker.
The only drawback would be that you couldn't both make persistent and volatile additions to the dictionary in one session.

In Vim, how to keep characters concealed even when cursor enters that line

I may have a unique situation here. I want gVim (gui version, in Linux) to keep concealed characters concealed no matter what, even when the cursor is on that line or that character gets selected. (It should be as close to if the characters never existed as possible.) Currently the concealed characters show themselves when the cursor enters that line, which causes text to jump around when scrolling and when selecting text.
We are using gView (read-only gVim) to view logs, so as to take advantage of its robust syntax highlighting. Problem is, these logs contain lots of escape characters and TTY color codes, that make reading difficult. (^[33mSomeText^[0m)
I'm using this line to hide them:
syntax match Ignore /\%o33\[[0-9]\{0,5}m/ conceal
Since the files are viewed by non-vim-experts, it looks glitchy and broken when the text un-conceals itself. (And also looks glitchy and broken if the color codes are present, and also looks glitchy and broken if the color codes are blacked-out to become invisible, but still show when selected and appear after copy/paste.)
This should be fine because these files are opened read-only in gview, with an extra set nomodifiable making it even more difficult to save the file. While it's possible to edit and attempt to save the logs, doing so is considered both an invalid thing to do, and a harmless thing to do, and requires enough Vim skills that if someone manages to edit a file they know what they're doing. The problem with being able to edit a line with concealed text does not apply.
If 'conceal' can't be configured to keep hidden text hidden no matter what, an acceptable alternative would be to replace the TTY color codes with whitespace when the file gets opened. But, this has to be done in read-only mode, and we can't have gview throwing up a save dialog on closing the window because the file has been modified by its .vimrc.
Note: I am in full control of the .vim script file sourced when these are read, but cannot control the existence of the TTY color codes or the code that opens the log files in gview. (i.e. I can't pass it through sed or anything like that.) The ideal solution is anything that can transparently nuke the color codes from within a .vimrc, but I'll hear any suggestions. The 'conceal' feature is just my most promising lead.
So, any ideas how to permanently get rid of these on file view without dialogs popping up on close?
:help conceal
When the "conceal" argument is given, the item is marked as concealable.
Whether or not it is actually concealed depends on the value of the
'conceallevel' option. The 'concealcursor' option is used to decide whether
concealable items in the current line are displayed unconcealed to be able to
edit the line.
:help concealcursor
Sets the modes in which text in the cursor line can also be concealed.
When the current mode is listed then concealing happens just like in
other lines.
n Normal mode
v Visual mode
i Insert mode
c Command line editing, for 'incsearch'
'v' applies to all lines in the Visual area, not only the cursor.
A useful value is "nc". This is used in help files. So long as you
are moving around text is concealed, but when starting to insert text
or selecting a Visual area the concealed text is displayed, so that
you can see what you are doing.
Keep in mind that the cursor position is not always where it's
displayed. E.g., when moving vertically it may change column.
Also, :help conceallevel
Determine how text with the "conceal" syntax attribute |:syn-conceal|
is shown:
Value Effect ~
0 Text is shown normally
1 Each block of concealed text is replaced with one
character. If the syntax item does not have a custom
replacement character defined (see |:syn-cchar|) the
character defined in 'listchars' is used (default is a
space).
It is highlighted with the "Conceal" highlight group.
2 Concealed text is completely hidden unless it has a
custom replacement character defined (see
|:syn-cchar|).
3 Concealed text is completely hidden.
Only one command is needed: set concealcursor=n
I might have a better idea—you can pass it through sed (using %!sed) or really do a bunch of other :substitute commands—whatever edits you need to get rid of the color codes.
When you’re done, make sure to set nomodified—this forces vim to think there haven’t been any changes!

VIM: Respect only current code block

I have started working on a huge PHP application that has thousands of lines of code in each file, with lots of huge if blocks, classes, and functions all existing in the same file. I'm not the only dev working on it, so I cannot refactor!
I have tried using the Tags List plugin but it does not really help. Is there any way to have VIM respect only a particular code block, and ignore the rest of the file? I am hoping for some or all of these features:
Enable line numbering only for the current code block, starting from 1 at the line containing the opening {, and showing no numbering for lines preceding it or after the closing }.
Searching with / would be restricted only to the block in question.
I am thinking along the lines of selecting the current block and editing it in a new buffer when enabling the mode, then replacing the existing block with the edited block when exiting the mode. However, I am having trouble actually implementing this feature. My current version is this:
map <F7> <Esc>mO<C-V>aBy:new<Return>p:set nu<Return>:set ft=php<Return>ggi<?php<Return><Esc>
map <F8> <Esc>ggdd<C-V>aBx:bp<Return>`O<C-V>aBp
However, this has several issues, such as the inability to perform incremental saves.
I would be very surprised if Vim allows the kind of line numbering you ask for.
This plugin (and 1 or 2 similar ones IIRC) allows you to visually select a region of your current file, work on it in another buffer and put everything back in its place in the original file on :w.
Even if it's not the solution you are wanting, I think the following can help you to solve your problem.
You can use phpfolding plugin, which folds by PHP syntax (functions, classes, methods, PhpDoc...)
You can then select a fold by pressing v$ over the closed fold and execute whatever you want with :whatever. For example, :s/this/self/g to substitute all this for self in the fold. When you press :, vim will automatically add '<,'> to denote following command it's only for the visually selected text.

Separate Vim spellfile for custom words

I just started using the spell checking feature in vim. According to the documentation, zg adds the current word to the first spellfile.
Is it recommended to create an own, empty spellfile, so that the English one doesn't get littered? If so: How do I create an empty spell list? An empty appropriately named file yields "E757: This does not look like a spell file".
Using your own additional spell files is both the recommended and default way of doing custom spelling. In Vim you have a 'root' spell file based on the current language and encoding, and an optional quantity of 'additional' spell files.
The easiest way to create an additional spell file (if you haven't already) is simply to add or remove a word using zg or zw - If 'spellfile' is empty, an new additional spell file will be created in the first writeable directory in 'runtimepath'.
The naming of spell files can be a bit tricky. Firstly, Vim takes a text file containing a list of words and converts it into a binary file which is a lot quicker to work with internally. The reason you're getting an error E757 is that Vim is attempting to load the binary spell file, but it's not finding the marker text at the start of the file, so it's bailing out.
To create your own spell files the filename needs to be in the format "mySpellFile.en.utf-8.add" where spelllang=en and encoding=utf-8.
