Vi - Matching Braces, Brackets, or Parentheses

%
This is a simple command for jumping to the matching brace, square bracket, or parentheses. For example, it can take you from the beginning of a function to the end with one key stroke. To delete everything between the pairs of {}, [], or (), issue the command: d% To replace text between pairs of braces, brackets, or parentheses, issue the command: c% You can also use this command to find out if an opening brace has been properly closed.

  • It is often recommended to enclose capital letters in a BibTeX file in braces, so the letters will not be transformed to lower case, when imported from LaTeX. This is an attempt to apply this rule to a BibTeX database file. DO NOT USE sed '...' input.bib > input.bib as it will empty the file! How it works: /^\s*[^@%]/ Apply the search-and-replace rule to lines that start (^) with zero or more white spaces (\s*), followed by any character ([...]) that is *NOT* a "@" or a "%" (^@%). s=<some stuff>=<other stuff>=g Search (s) for some stuff and replace by other stuff. Do that globally (g) for all matches in each processed line. \([A-Z][A-Z]*\)\([^}A-Z]\|},$\) Matches at least one uppercase letter ([A-Z][A-Z]*) followed by a character that is EITHER not "}" and not a capital letter ([^}A-Z]) OR (|) it actually IS a "}", which is followed by "," at the end of the line ($). Putting regular expressions in escaped parentheses (\( and \), respectively) allows to dereference the matched string later. {\1}\2 Replace the matched string by "{", followed by part 1 of the matched string (\1), followed by "}", followed by the second part of the matched string (\2). I tried this with GNU sed, only, version 4.2.1. Show Sample Output

    sed '/^\s*[^@%]/s=\([A-Z][A-Z]*\)\([^}A-Z]\|},$\)={\1}\2=g' literature.bib > output.bib

  • This function counts the opening and closing braces in a string. This is useful if you have eg long boolean expressions with many braces and you simply want to check if you didn't forget to close one. Show Sample Output

    countbraces () { COUNT_OPENING=$(echo $1 | grep -o "(" | wc -l); COUNT_CLOSING=$(echo $1 | grep -o ")" | wc -l); echo Opening: $COUNT_OPENING; echo Closing: $COUNT_CLOSING; }
