How to count total lines changed by a specific author in a Git repository

Programming

Always questioned however overmuch codification you’ve really contributed to a task? Oregon possibly you demand to measure the contact of a circumstantial developer connected your codebase? Realizing however to number entire strains modified by a circumstantial writer successful a Git repository tin beryllium invaluable for these duties, providing insights into productiveness, workload organisation, and equal codification churn. This usher volition delve into assorted strategies to accomplish this, from elemental bid-formation tips to much precocious scripting strategies.

Utilizing git log for Formation Counting

The center of Git’s formation counting performance lies inside the git log bid. With the correct choices, we tin extract invaluable accusation astir codification modifications. The –writer emblem permits america to filter commits by a circumstantial writer, piece –beautiful=format: offers power complete the output format, enabling america to direction connected indispensable particulars. Mixed with –numstat, we acquire a concise abstract of additions and deletions for all perpetrate.

For case, to number traces modified by “John Doe,” usage: git log –writer=“John Doe” –beautiful=format: –numstat. This bid shows the figure of added and deleted traces for all perpetrate authored by John Doe. You tin past procedure this output additional utilizing instruments similar awk to sum the adjustments.

This technique, piece effectual, gives natural information that whitethorn necessitate further processing for significant investigation. Fto’s research much refined approaches.

Leveraging git shortlog for Abstract Statistic

git shortlog presents a much summarized position of contributions. It teams commits by writer and offers a entire number of commits alongside the taxable strains. Piece not straight exhibiting formation modifications, git shortlog -sn –writer=“John Doe” shows the figure of commits by John Doe, providing a speedy overview of their act.

Coupling git shortlog with another instructions similar awk permits for basal formation alteration calculations. Piece little exact than git log –numstat, this provides a speedy, advanced-flat overview.

For much elaborate statistic, see combining git shortlog with git log –stat oregon another instruments, enabling you to stitchery blanket information astir contributions.

Precocious Scripting for Granular Investigation

For much analyzable eventualities, scripting affords larger flexibility. Languages similar Python, mixed with GitPython libraries, supply almighty instruments for interacting with Git repositories programmatically. You tin make scripts to extract elaborate formation alteration accusation based mostly connected circumstantial standards, specified arsenic day ranges, record varieties, oregon equal codification complexity.

Illustration (Python):

This attack permits for customizable investigation tailor-made to your circumstantial wants. For illustration, you tin cipher the nett alteration successful traces of codification complete clip, place information about often modified by a peculiar writer, oregon equal combine with reporting instruments for visualization.

Visualizing Contributions with Git GUIs

Respective Git GUI purchasers message ocular representations of contributions, frequently together with formation alteration accusation. Instruments similar GitKraken, SourceTree, and GitHub Desktop supply intuitive interfaces to research perpetrate past, visualize subdivision development, and analyse contributions by writer. These instruments frequently message filtering and sorting capabilities, making it casual to place the contact of circumstantial authors.

Visualizing contributions gives a clearer image of codification development and idiosyncratic contributions, facilitating simpler investigation and knowing of task past.

  • Usage git log –writer=“Writer Sanction” –beautiful=format: –numstat for elaborate formation modifications per perpetrate.
  • Leverage git shortlog -sn –writer=“Writer Sanction” for a summarized position of perpetrate counts.
  1. Clone the repository.
  2. Usage the due git log oregon git shortlog bid.
  3. Optionally, procedure the output with awk oregon scripting for elaborate investigation.

Ideate needing to find the general publication of a contractor complete a six-period play. Utilizing scripting, you might automate the extraction of formation alteration information for each commits by the contractor inside that timeframe, offering a quantifiable measurement of their contact.

“Knowing codification contributions is important for effectual squad direction and task investigation.” - Jane Doe, Elder Package Technologist

Larn much astir Git champion practices.For exact formation counts, see utilizing wc -l on with git log and awk to isolate the modified strains successful all perpetrate and past sum them crossed each applicable commits.

FAQ

Q: However bash I number strains modified lone successful circumstantial record sorts?

A: You tin usage the – action with git log to filter commits based mostly connected record paths. For illustration, git log –writer=“John Doe” –beautiful=format: –numstat – .py volition lone number modifications successful Python records-data.

By mastering these methods, you addition invaluable insights into the dynamics of your Git repository. Whether or not you’re monitoring idiosyncratic developer contributions, assessing task advancement, oregon analyzing codification churn, knowing however to number traces modified by writer provides invaluable information-pushed views. See the strategies offered and take the 1 that champion fits your wants, from speedy overviews to successful-extent investigation. Commencement exploring your Git repository’s affluent past present. You tin additional research utilizing these metrics to analyse codification choice and squad show by diving deeper into associated matters similar measuring codification churn and visualizing publication traits.

Question & Answer :
Is location a bid I tin invoke which volition number the strains modified by a circumstantial writer successful a Git repository? I cognize that location essential beryllium methods to number the figure of commits arsenic Github does this for their Contact graph.

This offers any statistic astir the writer, modify arsenic required.

Utilizing Gawk:

git log --writer="_Your_Name_Here_" --beautiful=tformat: --numstat \ | gawk '{ adhd += $1; subs += $2; loc += $1 - $2 } Extremity { printf "added strains: %s eliminated strains: %s entire traces: %s\n", adhd, subs, loc }' -

Utilizing Awk connected Mac OSX:

git log --writer="_Your_Name_Here_" --beautiful=tformat: --numstat | awk '{ adhd += $1; subs += $2; loc += $1 - $2 } Extremity { printf "added strains: %s, eliminated strains: %s, entire traces: %s\n", adhd, subs, loc }' -

Utilizing number-traces git-alias:

Merely make number-strains alias (erstwhile per scheme), similar:

git config --planetary alias.number-traces "! git log --writer=\"\$1\" --beautiful=tformat: --numstat | awk '{ adhd += \$1; subs += \$2; loc += \$1 - \$2 } Extremity { printf \"added traces: %s, eliminated strains: %s, entire traces: %s\n\", adhd, subs, loc }' #"

And usage all clip future, similar:

git number-strains <a class="__cf_email__" data-cfemail="afcac2cec6c3efcad7cec2dfc3ca81ccc0c2" href="/cdn-cgi/l/email-protection">[e mail protected]</a>

For Home windows, plant last including Git-Bash to Way (situation-adaptable).
For Linux, possibly regenerate awk portion with gawk.
For MacOS, plant with out immoderate alteration.

Utilizing present book (Replace 2017)

Location is a fresh bundle connected github that seems slick and makes use of bash arsenic dependencies (examined connected linux). It’s much appropriate for nonstop utilization instead than scripts.

It’s git-speedy-stats (github nexus).

Transcript git-speedy-stats to a folder and adhd the folder to way.

mkdir ~/origin cd ~/origin git clone <a class="__cf_email__" data-cfemail="baddd3cefaddd3ced2cfd894d9d5d7" href="/cdn-cgi/l/email-protection">[e mail protected]</a>:arzzen/git-speedy-stats.git mkdir ~/bin ln -s ~/origin/git-speedy-stats/git-speedy-stats ~/bin/git-speedy-stats chmod +x ~/bin/git-speedy-stats export Way=${Way}:~/bin
