2013-04-14completion: small optimizationLibravatar Felipe Contreras1-4/+4
No need to calculate a new $c with a space if we are not going to do anything it with it. There should be no functional changes, except that a word "foo " with no suffixes can't be matched. But $cur cannot have a space at the end anyway. So it's safe. Based on the code from SZEDER Gábor.

2013-04-14completion: inline __gitcomp_1 to its sole callsiteLibravatar Felipe Contreras1-15/+11
There is no point in calling a separate function that is only used in one place. Especially considering that there's no need to call compgen, and we traverse the words ourselves both in __gitcompadd, and __gitcomp_1. Let's squash the functions together, and traverse only once. This improves performance. For N number of words: == 1 == original: 0.002s new: 0.000s == 10 == original: 0.005s new: 0.001s == 100 == original: 0.009s new: 0.006s == 1000 == original: 0.027s new: 0.019s == 10000 == original: 0.163s new: 0.151s == 100000 == original: 1.555s new: 1.497s No functional changes.

2013-04-14completion: get rid of compgenLibravatar Felipe Contreras1-5/+10
The functionality we use from compgen is not much, we can do the same manually, with drastic improvements in speed, especially when dealing with only a few words. This patch also has the sideffect that brekage reported by Jeroen Meijer and SZEDER Gábor gets fixed because we no longer expand the resulting words. Here are some numbers filtering N amount of words: == 1 == original: 0.002s new: 0.000s == 10 == original: 0.002s new: 0.000s == 100 == original: 0.003s new: 0.002s == 1000 == original: 0.012s new: 0.011s == 10000 == original: 0.056s new: 0.066s == 100000 == original: 2.669s new: 0.622s If the results are not narrowed: == 1 == original: 0.002s new: 0.000s == 10 == original: 0.002s new: 0.001s == 100 == original: 0.004s new: 0.004s == 1000 == original: 0.020s new: 0.015s == 10000 == original: 0.101s new: 0.355s == 100000 == original: 2.850s new: 31.941s So, unless 'git checkout <tab>' usually gives you more than 10000 results, you'll get an improvement :) Other possible solutions perform better after 1000 words, but worst if less than that: COMPREPLY=($(awk -v cur="$3" -v pre="$2" -v suf="$4" '$0 ~ cur { print pre$0suf }' <<< "$1" )) COMPREPLY=($(printf -- "$2%s$4\n" $1 | grep "^$2$3")) Signed-off-by: Felipe Contreras <felipe.contreras@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-03-11git-completion.bash: zsh does not implement function redirection correctlyLibravatar Matthieu Moy1-5/+11
A recent change added functions whose entire standard error stream is redirected to /dev/null using a construct that is valid POSIX.1 but is not widely used: funcname () { cd "$1" && run some command "$2" } 2>/dev/null Even though this file is "git-completion.bash", zsh completion support dot-sources it (instead of asking bash to grok it like tcsh completion does), and zsh does not implement this redirection correctly. With zsh, trying to complete an inexistant directory gave this: git add no-such-dir/__git_ls_files_helper:cd:2: no such file or directory: no-such-dir/ Also these functions use "cd" to first go somewhere else before running a command, but the location the caller wants them to go that is given as an argument to them should not be affected by CDPATH variable the users may have set for their interactive session. To fix both of these, wrap the body of the function in a subshell, unset CDPATH at the beginning of the subshell, and redirect the standard error stream of the subshell to /dev/null.

2013-03-04submodule: add 'deinit' commandLibravatar Jens Lehmann1-1/+1
With "git submodule init" the user is able to tell git he cares about one or more submodules and wants to have it populated on the next call to "git submodule update". But currently there is no easy way he could tell git he does not care about a submodule anymore and wants to get rid of his local work tree (except he knows a lot about submodule internals and removes the "submodule.$name.url" setting from .git/config together with the work tree himself). Help those users by providing a 'deinit' command. This removes the whole submodule.<name> section from .git/config (either for the given submodule(s) or for all those which have been initialized if '.' is used) together with their work tree. Fail if the current work tree contains modifications (unless forced), but don't complain when either the work tree is already removed or no settings are found in .git/config. Add tests and link the man pages of "git submodule deinit" and "git rm" to assist the user in deciding whether removing or unregistering the submodule is the right thing to do for him.

2013-01-24t9902: protect test from stray build artifactsLibravatar Junio C Hamano1-1/+10
When you have random build artifacts in your build directory, left behind by running "make" while on another branch, the "git help -a" command run by __git_list_all_commands in the completion script that is being tested does not have a way to know that they are not part of the subcommands this build will ship. Such extra subcommands may come from the user's $PATH. They will interfere with the tests that expect a certain prefix to uniquely expand to a known completion. Instrument the completion script and give it a way for us to tell what (subset of) subcommands we are going to ship. Also add a test to "git --help <prefix><TAB>" expansion. It needs to show not just commands but some selected documentation pages. Based on an idea by Jeff King. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Some users or projects prefer different algorithms over others, e.g. patience over myers or similar. However, specifying appropriate argument every time diff is to be used is impractical. Moreover, creating an alias doesn't play nicely with other tools based on diff (git-show for instance). Hence, a configuration variable which is able to set specific algorithm is needed. For now, these four values are accepted: 'myers' (which has the same effect as not setting the config variable at all), 'minimal', 'patience' and 'histogram'.

2013-01-11git-completion.bash: add support for path completionLibravatar Manlio Perillo1-15/+240
The git-completion.bash script did not implemented full, git aware, support to complete paths, for git commands that operate on files within the current working directory or the index. As an example: git add <TAB> will suggest all files in the current working directory, including ignored files and files that have not been modified. Support path completion, for git commands where the non-option arguments always refer to paths within the current working directory or the index, as follows: * the path completion for the "git rm" and "git ls-files" commands will suggest all cached files. * the path completion for the "git add" command will suggest all untracked and modified files. Ignored files are excluded. * the path completion for the "git clean" command will suggest all untracked files. Ignored files are excluded. * the path completion for the "git mv" command will suggest all cached files when expanding the first argument, and all untracked and cached files for subsequent arguments. In the latter case, empty directories are included and ignored files are excluded. * the path completion for the "git commit" command will suggest all files that have been modified from the HEAD, if HEAD exists, otherwise it will suggest all cached files. For all affected commands, completion will always stop at directory boundary. Only standard ignored files are excluded, using the --exclude-standard option of the ls-files command. When using a recent Bash version, Git path completion will be the same as builtin file completion, e.g. git add contrib/ will suggest relative file names.

2012-11-24Completion must sort before using uniqLibravatar Marc Khouzam1-1/+1
The user can be presented with invalid completion results when trying to complete a 'git checkout' command. This can happen when using a branch name prefix that matches multiple remote branches. For example, if available branches are: master remotes/GitHub/maint remotes/GitHub/master remotes/origin/maint remotes/origin/master When performing completion on 'git checkout ma' the user will be given the choices: maint master However, 'git checkout maint' will fail in this case, although completion previously said 'maint' was valid. Furthermore, when performing completion on 'git checkout mai', no choices will be suggested. So, the user is first told that the branch name 'maint' is valid, but when trying to complete 'mai' into 'maint', that completion is no longer valid. The completion results should never propose 'maint' as a valid branch name, since 'git checkout' will refuse it. The reason for this bug is that the uniq program only works with sorted input. The man page states "uniq prints the unique lines in a sorted file". When __git_refs uses the guess heuristic employed by checkout for tracking branches it wants to consider remote branches but only if the branch name is unique. To do that, it calls 'uniq -u'. However the input given to 'uniq -u' is not sorted. Therefore, in the above example, when dealing with 'git checkout ma', "__git_refs '' 1" will find the following list: master maint master maint master which, when passed to 'uniq -u' will remain the same. Therefore 'maint' will be wrongly suggested as a valid option. When dealing with 'git checkout mai', the list will be: maint maint which happens to be sorted and will be emptied by 'uniq -u', properly ignoring 'maint'. A solution for preventing the completion script from suggesting such invalid branch names is to first call 'sort' and then 'uniq -u'.

2012-11-19completion: start moving to the new zsh completionLibravatar Felipe Contreras1-43/+61
Zsh's bash completion emulation is buggy, not properly maintained, and we have some workarounds in place for different bugs that appeared in various versions. Since I'm the only one that has worked on that code lately[1], it might make snese to use the code I wrote specifically for git. The advantages are: 1) Less workarounds * No need to hack __get_comp_words_by_ref * No need to hack IFS or words 2) Improved features * 'git show master' now properly adds a space at the end (IFS bug) * 'git checkout --conflict=' now properly returns the sub-items (missing feature) 3) Consolidated code * It's all now in a single chunk, and it's basically the same as git-completion.zsh Since there's some interest in moving the zsh-specific code out of this script, lets go ahead and warn the users that they should be using git-completion.zsh.

As reported by Jeroen Meijer[1]; the current code doesn't deal properly with items (tags, branches, etc.) that have ${} in them because they get expaned by bash while using compgen. A simple solution is to quote the items so they get expanded properly (\$\{\}). In order to achieve that I took bash-completion's quote() function, which is rather simple, and renamed it to __git_quote() as per Jeff King's suggestion. Solves the original problem for me.
